TY - JOUR T1 - A feasibility study on Pd/Mg application in historically contaminated sediments and PCB spiked substrates AN - 21065682; 11186767 AB - A vast majority of literature on bimetals deals with aqueous contaminants, very little being on organics strongly adsorbed on sediments and hence very challenging to remediate. Having previously reported materials, mechanistic and parametric aspects of PCB dechlorination with Pd/Mg bimetals, here we evaluate their ability to dechlorinate (i) PCBs spiked in clean clays and sediments and (ii) historically contaminated aged sediments (Waukegan Harbor, WHS). It was determined that while water, as a medium, dechlorinated low surface area clays it was ineffective with high surface area clays and sediments. Dechlorination was governed by desorption of PCBs, hence addition of 10-25% ethanol improved dechlorination performance. Triton X-100, a surfactant, effectively desorbed PCBs from WHS but their dechlorination was not observed. Investigating possible causes, we found that while (i) Pd /Mg completely dechlorinated multi-component commercial PCB mixtures (i.e. complex PCB distribution in WHS did not limit Pd/Mg effectiveness) and (ii) active components in extraction media did not inhibit dechlorination, sulfide in WHS was poisoning Pd, compromising its activity.

We sampled sediments, adult chironomids, terrestrial insects, riparian spiders (Tetragnathidae, Araneidae, and Mecynogea lemniscata), and upland spiders (Araneidae) along a sediment contamination gradient. Stable isotopes ( delta super(13)C, delta super(15)N) indicated that riparian spiders primarily consumed aquatic insects whereas upland spiders consumed terrestrial insects. PCBs in chironomids (mean 1240 ng/g among sites) were 2 orders of magnitude higher than terrestrial insects (15.2 ng/g), similar to differences between riparian (820-2012 ng/g) and upland spiders (30 ng/g). Riparian spider PCBs were positively correlated with sediment concentrations for all taxa (r super(2) = 0.44-0.87). We calculated spider-based wildlife values (WVs, the minimum spider PCB concentrations causing physiologically significant doses in consumers) to assess exposure risks for arachnivorous birds. Spider concentrations exceeded WVs for most birds at heavily contaminated sites and were 14-fold higher for the most sensitive species (chickadee nestlings, Poecile spp.). Spiders are abundant and ubiquitous in riparian habitats, where they depend on aquatic insect prey. These traits, along with the high degree of spatial correlation between spider and sediment concentrations we observed, suggest that they are model indicator species for monitoring contaminated sediment sites and assessing risks associated with contaminant flux into terrestrial ecosystems.

However, in our companion study (Ahlborn et al., 2009), continuous exposure to 85ppm sodium arsenic (from gestational day 8 to postnatal day 365) did not result in increased tumor incidence, but rather in a significant reduction (0% tumor incidence). The purpose of the present study was to examine the gene expression responses that may lead to the apparent protective effect of continuous arsenic exposure. Genes in many functional categories including cellular growth and proliferation, gene expression, cell death, oxidative stress, protein ubiquitination, and mitochondrial dysfunction were altered by continuous arsenic treatment. Many of these genes are known to be involved in liver cancer. One such gene associated with rodent hepatocarcinogenesis, Scd1, encodes stearoyl-CoA desaturase and was down-regulated by continuous arsenic treatment. An overlap between the genes in our study affected by continuous arsenic exposure and those from the literature affected by long-term caloric restriction suggests that reduction in the spontaneous tumor incidence under both conditions may involve similar gene pathways such as fatty acid metabolism, apoptosis, and stress response.

In general, environmental assessors are interested in empirical methodologies that can be applied to a broad range of environmental media (e.g., soils, sediments, etc.) and situations. To date, no unified guidance has been adopted, and site investigations usually involve a tiered process with multiple analyses. We propose a multivariate analysis methodology utilizing discriminant analysis with clustered chemical concentrations as a novel application to environmental site assessments that determine, in relative order of magnitude, contaminated chemicals. Finite mixture models are presented as a means to assess latent chemical clusters with some basis in statistical inference. The methodology is illustrated with a typical localized data set containing total metal and metalloid (i.e., chemical) concentrations, extracted from bulk soil collected from reference and site-related locations, obtained from a former military installation in the southeast United Sates. The illustration is particularly applicable because site-related soils inherently possessed higher background chemical levels than reference soils, which biased conventional analyses. However, contrasting chemical compositions were inferred within site-related samples illustrating the versatility of the proposed methodology. Using these results along with known information regarding the history of contamination at the site, a qualitative and quantitative assessment of contaminated chemicals was made. Results are intended for illustration purposes only and are discussed within the context of environmental site assessment.

13268484 AB - We use a regional-scale, three-dimensional atmospheric model to evaluate U.S. air quality effects that would result from replacing HFC-134a in automobile air conditioners in the U.S. with HFO-1234yf. Although HFO-1234yf produces tropospheric ozone, the incremental amount is small, averaging less than 0.01% of total ozone formed during the simulation. We show that this production of ozone could be compensated for by a modest improvement in air conditioner efficiency. Atmospheric decomposition of HFO-1234yf produces trifluoroacetic acid (TFA), which is subject to wet and dry deposition. Deposition and concentrations of TFA are spatially variable due to HFO-1234yf's short atmospheric lifetime, with more localized peaks and less global transport when compared to HFC-134a. Over the 2.5 month simulation, deposition of TFA in the continental U.S. from mobile air conditioners averages 0.24 kg km-2, substantially higher than previous estimates from all sources of current hydrofluorocarbons. Automobile air conditioning HFO-1234yf emissions are predicted to produce concentrations of TFA in Eastern U.S. rainfall at least double the values currently observed from all sources, natural and man-made. Our model predicts peak concentrations in rainfall of 1264 ng L-1, a level that is 80X lower than the lowest level considered safe for the most sensitive aquatic organisms.

13268482 AB - We apply a concept derived from food web ecology to large-scale spatial patterns of material supply within and between watersheds and coasts by generalizing the definition 'resource shed' to source areas for materials supplied to a receptor (e.g., a point location) over a specified time interval. Independent hydrologic and hydrodynamic models, coupled with a particle tracking model, were used to delimit resource shed total spatial extent and relative contributory importance for selected receptors in Lake Erie (North America) over varying time intervals. One resource shed was extended into the Maumee River watershed (OH) by integrating the lake and hydrologic models. Model validation was achieved through comparison with data from the 2005 International Field Years on Lake Erie (IFYLE) study. Resource shed size, orientation, and internal structure varied with receptor location, in-lake circulation, terrestrial precipitation, time interval, and season. River plume extent and interaction were illustrated, and model integration revealed the relative contributory importance of subwatershed catchments to an off-shore receptor.

While nutrients, canopy cover, and sediment fines contribute to these impairments, these stressors are often defined, at least in part, by their impacts on periphyton. Path analysis can extend these assessments to impacts on invertebrates and fish by characterizing the direct and indirect relationships among variables along defined model pathways. With data from headwater tributaries in the Little Miami River, Ohio, we tested models of the impacts of nutrients [total nitrogen (TN), total phosphorus (TP), and the nitrogen to phosphorus (N/P) ratio], the percentage of (%) open canopy, and the % sand and fines on three periphyton metrics [periphytic ash-free dry mass (AFDM), the percent abundance of cyanobacteria (% cyanobacteria), and the percent abundance of Chlorophyta (% Chlorophyta)] and, in turn, on selected invertebrate or fish metrics. Our objective was to develop and evaluate a statistical model that assesses the direct and indirect impacts of excess nutrients on macroinvertebrate and fish in these streams and demonstrate how this approach might be applicable elsewhere. The results suggest indirect pathways for the influences of nutrients, canopy cover, and fine bedded sediments on invertebrates or fish that are mediated by their influences on periphyton. This is in addition to any direct impacts of these stressors on the invertebrate and fish metrics. In most models, all three periphyton metrics increased with % open canopy. Periphytic AFDM increased with TN, while % cyanobacteria decreased. The % cyanobacteria also decreased with % sand and fines, but % Chlorophyta increased. The metrics, percent abundance of (%) three most dominant (macroinvertebrate) taxa, % Trichoptera, and % herbivorous fish all increased with periphytic AFDM, while % climbers, % swimmers, and %Lepomis cyanellus Rafinesque decreased. Lepomis cyanellus is an indicator species, because it is generally common in these streams and relatively tolerant to various common environmental stressors. The % three most dominant macroinvertebrate taxa increased while % Hydropsychidae (Trichoptera) and %L. cyanellus decreased with % cyanobacteria. The % Trichoptera and %L. cyanellus increased with % Chlorophyta. Some macroinvertebrate metrics, such as the % burrowers and number of burrower taxa, did not have any statistically significant relationships with the periphyton metrics but did exhibit a direct pathway with % sand and fines. These analyses illustrate how path analysis can be used to estimate the relationships among the variables in a conceptual model, modify the model, assess the relative importance of different paths, and explore responses resulting from stressors with interacting and indirect impacts.

The recent emergence and reemergence of infectious diseases appears to be driven by globalization and ecological disruption. We propose that habitat destruction and biodiversity loss associated with biotic homogenization can increase the incidence and distribution of infectious diseases affecting humans. The clearest connection between biotic homogenization and infectious disease is the spread of nonindigenous vectors and pathogens. The loss of predators and hosts that dilute pathogen transmission can also increase the incidence of vectorborne illnesses. Other mechanisms include enhanced abiotic conditions for pathogens and vectors and higher host-pathogen encounter rates. Improved understanding of these causal mechanisms can inform decisionmaking on biodiversity conservation as an effective way to protect human health.

Two burning waste dump sites in Mexico were sampled using high-volume samplers mounted to a mobile sampling boom. Concurrent measurements of CO and CO2 allowed determination of emission factors via the carbon balance method. PCDD/F emission factors averaged 823 ng toxic equivalency (TEQ)/kg Cburned (N = 8, 68% relative standard deviation, RSD), a value at least five times higher than those from previous tests with domestic waste burned in barrels and approximately 2000 times higher than those from stacks of modern municipal waste combustors. These emission factors appear to be related to combustion quality, as conditions conducive to smoldering combustion, rather than flaming combustion, resulted in higher emission factors. Emissions of 40 PBDE congeners, likely originating from brominated flame retardants, averaged 724 *mg/kg Cburned (RSD = 96%) and had congener patterns similar to those of reported atmospheric sampling. Emissions of PBDDs/Fs were similar in magnitude to their chlorinated counterparts, averaging 470 ng TEQ/kg Cburned (RSD = 105%), and may originate as reaction products of PBDE combustion or as thermally desorbed impurities from the PBDE flame retardant.

Cesium and cobalt chloride salts were used as surrogates for cesium-137 and cobalt-60. Studies were conducted in biofilm annular reactors containing heavily corroded iron surfaces formed under shear and constantly submerged in drinking water. Cesium was not detected on the corroded iron surface after equilibration with 10 and 100mgL super(-1) solutions of cesium chloride, but cobalt was detected on corroded iron coupons at both initial concentrations. The amount of adhered cobalt decreased over the next six weeks, but was still present when monitoring stopped. X-ray absorption near-edge spectroscopy (XANES) showed that adhered cobalt was in the III oxidation state. The adsorbed cobalt was strongly resistant to decontamination by various physicochemical methods. Simulated flushing, use of free chlorine and dilute ammonia were found to be ineffective whereas use of aggressive methods like 14.5M ammonia and 0.36M sulfuric acid removed 37 and 92% of the sorbed cobalt, respectively.

Model simulations were conducted with and without the NO2a- chemistry. The largest impact of the NO2a- chemistry in the eastern U.S. occurred in the northeast and in the western U.S. occurred in Los Angeles. While the single largest daily maximum 8-h ozone (O3) increased by 9aappbv in eastern U.S. and 6aappbv in western U.S., increases on most days were much lower. No appreciable change in model performance statistics for surface-level O3 predictions relative to measurements is noted between simulations with and without the NO2a- chemistry.

These species and the ecological services they provide are important to the peoples surrounding the North Atlantic (i.e. the Atlantic Ocean north of the equator). super()There are several different legal and/or regulatory tools available to ensure that cold-water corals in the North Atlantic are protected along with the ecological services they provide. Through such tools, many protected areas have been designated or are under consideration in the North Atlantic to protect cold-water coral habitats. Although the designation and labeling varies, e.g. National Marine Conservation Area (Canada), Special Area of Conservation (European Union), or Habitat Area of Particular Concern (USA), all of these designations aim to provide protection into the future to vulnerable habitats like cold-water corals.

Two types of temporal behaviors, a periodic structure and nugget effect, plus one or two temporal structures, were identified and interpreted. These correspond to characteristics of karst systems, such as the catchment area, percent of conduit flow, and general degree of karst development. Springs were grouped into three categories based on their ranges (e.g., residence time) obtained by variogram analysis. The first group of springs include those that present the same temporal behaviour in variograms of discharge and EC. These springs are characterized by generally constant EC with increasing discharge suggesting the existence of a large underground reservoir. The second group of springs are those with varying temporal periodic behavior in variograms of discharge and EC. Positive correlation between discharge and EC values is the main characteristic of these springs and is interpreted to result from a piston-flow system in poorly developed karst aquifers. The third group of springs includes those that exhibit different temporal behaviors when compared with the periodic and non-periodic variograms. This group exhibits a negative correlation in scatterplots of discharge versus EC values suggesting a well-developed solution-conduit system that facilitates rapid response of the karst system to precipitation events. This study's results document the role of variogram analysis in delineating temporal structures of spring behaviors by means of time series of discharge and EC. Variogram analysis can be considered as a valuable tool for hydrogeological investigations in karstic terranes.

AN - 734269022; 19814653 AB - The Homeland Security Presidential Directive #8 (HSPD-8) for National Emergency Preparedness was issued to " establish policies to strengthen the preparedness of the United States to prevent and respond to threatened or actual domestic terrorist attacks, major disasters, and other emergencies by requiring a national domestic all- hazards preparedness goal. "In response to HSPD-8 and HSPD-22 (classified) on Domestic Chemical Defense, the US Environmental Protection Agency (US EPA) National Homeland Security Research Center (NHSRC) is developing health-based Provisional Advisory Levels (PALs) for priority chemicals (including chemical warfare agents, pesticides, and toxic industrial chemicals) in air and drinking water. PALs are temporary values that will neither be promulgated, nor be formally issued as regulatory guidance. They are intended to be used at the discretion of risk managers in emergency situations. The PAL Program provides advisory exposure levels for chemical agents to assist in emergency planning and response decision-making, and to aid in making informed risk management decisions for evacuation, temporary re-entry into affected areas, and resumed-use of infrastructure, such as water resources. These risk management decisions may be made at the federal, state, and local levels. Three exposure levels (PAL 1, PAL 2, and PAL 3), distinguished by severity of toxic effects, are developed for 24-hour, 30-day, 90-day, and 2-year durations for potential exposure to drinking water and ambient air by the general public. Developed PALs are evaluated both by a US EPA working group, and an external multidisciplinary panel to ensure scientific credibility and wide acceptance. In this Special Issue publication, we present background information on the PAL program, the methodology used in deriving PALs, and the technical support documents for the derivation of PALs for acrylonitrile, hydrogen sulfide, and phosgene.

AN - 734197201; 19841129 AB - The skin is an organ that is highly sensitive to chronic arsenic (As) exposure. Skin lesions such as hyperkeratoses (HKs) are common early manifestations of arsenicosis in humans. HKs can be precursor lesions of nonmelanoma skin cancers (NMSCs), but the driving forces behind their formation and how they may ultimately progress to NMSCs are unknown. The goal of this study was to examine the global gene expression profiles of As-related HKs in an effort to better understand gene expression changes that are potentially associated with early stages of As carcinogenesis. HK biopsies were removed from individuals living in an arsenicosis-endemic region in Inner Mongolia who had been exposed to high As levels in their drinking water for >20 years. Gene expression profiling was performed on RNA isolated from 7 individuals in this group and from 4 lesion-free skin samples from healthy individuals. Consistent with the pathological characteristics of the HK lesions, major functional categories and known canonical pathways represented by altered transcripts include those involved in development, differentiation, apoptosis, proliferation, and stress response. The results of this study may help define a signature profile of gene expression changes associated with long-term As exposure in the skin.

AN - 734161746; 19692099 AB - As defined by the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), a surface washing agent (SWA) is a product that removes oil from solid surfaces, such as beaches, rocks, and concrete, through a detergency mechanism and that does not involve dispersing or solubilizing the oil into the water column. Commercial products require testing to qualify for listing on the NCP Product Schedule. Such testing is conducted both for toxicity and effectiveness. Protocols currently exist for bioremediation agents and dispersants, but not SWAs. The US Environmental Protection Agency (EPA) is developing a laboratory testing protocol to evaluate the effectiveness of SWAs in removing crude oil from a solid substrate. This paper summarizes some of the defining research supporting this new protocol. Multiple variables were tested to determine their effect on SWA performance. The protocol was most sensitive to SWA-to-oil ratio and rotational speed of mixing. Less sensitive variables were contact time, mixing time, and SWA concentration when total applied mass of active product was constant. EPA recommendations for the testing protocol will be made following round robin testing.

AN - 734139729; 19382823 AB - The combined excretion of active pharmaceutical ingredients (APIs) via urine and feces is considered the primary route by which APIs from human pharmaceuticals enter the environment. Disposal of unwanted, leftover medications by flushing into sewers has been considered a secondary route-one that does not contribute substantially to overall environmental loadings. The present study presents the first comprehensive examination of secondary routes of API release to the environment and for direct but unintentional human exposure. These include bathing, washing, and laundering, all of which release APIs remaining on the skin from the use of high-content dermal applications or from excretion to the skin via sweating, and disposal of unused and partially used high-content devices. Also discussed are the health hazards associated with: partially used devices, medication disposal practices of consumers, and interpersonal dermal transfer of API residues. Understanding these secondary routes is important from the perspective of pollution prevention, because actions can be designed more easily for reducing the environmental impact of APIs compared with the route of direct excretion (via urine and feces), for reducing the incidence of unintentional and purposeful poisonings of humans and pets, and for improving the quality and cost-effectiveness of health care. Overall, unintentional exposure to APIs for humans via these routes is possibly more important than exposure to trace residues recycled from the environment in drinking water or foods.

Hydrous manganese oxides (HMO) are seen to coat rocks further downstream during some seasons. Synoptic spatial sampling was used to assess the fate and transport of Cu, Fe, Mn, and Zn during different years and hydrological seasons. Visual-MINTEQ was used to compare observed and model-calculated percentage particulate Cu and Zn as influenced by sorption to both HFO and HMO and aqueous complexation with dissolved organic carbon (DOC). Over distance, Cu and Fe were transported predominantly in the particulate phase, Mn in the dissolved phase, and Zn was intermediate in its distribution, with generally about 50% being in each phase. Under higher flows, a larger fraction of the total metals was present in the dissolved phase, along with a lower total suspended sediment (TSS) concentration. This is consistent with the source of TSS being predominantly in-stream precipitation of metals, which might be kinetically limited under higher flows. Modeling results most closely represented observed percentage particulate Cu under lower flows; a strong seasonal trend was not evident for Zn. Model over-predictions of percentage particulate Cu suggest non-equilibrium with sorbent phases or that something in addition to DOC was keeping a portion of the Cu in solution; under-predictions for Zn suggest an additional sorbent. Differences between observed and modeled particulate varied significantly between sites and seasons; ranging from 1 to 54% for Cu and 1 to 34% for Zn overall.

AN - 733785181; 19740040 AB - To explain the underlying causes of apparently stochastic disease, current research is focusing on systems biology approaches wherein individual genetic makeup and specific 'gene-environment' interactions are considered. This is an extraordinarily complex task because both the environmental exposure profiles and the specific genetic susceptibilities presumably have large variance components. In this article, the focus is on the initial steps along the path to disease outcome namely environmental uptake, biologically available dose, and preclinical effect. The general approach is to articulate a conceptual model and identify biomarker measurements that could populate the model with hard data. Between-subject variance components from different exposure studies are used to estimate the source and magnitude of the variability of biomarker measurements. The intent is to determine the relative effects of different biological media (breath or blood), environmental compounds and their metabolites, different concentration levels, and levels of environmental exposure control. Examples are drawn from three distinct exposure biomarker studies performed by the US Environmental Protection Agency that studied aliphatic and aromatic hydrocarbons, trichloroethylene and methyl tertiary butyl ether. All results are based on empirical biomarker measurements of breath and blood from human subjects; biological specimens were collected under appropriate Institutional Review Board protocols with informed consent of the subjects. The ultimate goal of this work is to develop a framework for eventually assessing the total susceptibility ranges along the toxicological pathway from exposure to effect. The investigation showed that exposures are a greater contributor to biomarker variance than are internal biological parameters.

AN - 733591434; 19943641 AB - High levels (microg/g lw) of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) were measured in peregrine falcon eggs from California (n = 90 eggs from 52 birds, 38 nest sites, collected 1986-2007, SigmaPBDEs median = 4.53, range = 0.08-53.1). Over the past 22 years, PBDE levels more than tripled each decade in the eggs, whereas PCB levels had no significant changes. PBDE levels were highest in eggs from major California cities ("Big Cities"), whereas PCBs showed no difference across the regions. For PBDEs, Big City eggs had markedly different patterns from Coastal eggs: BDE-209 and the higher brominated PBDEs (hexa-nona) were dominant congeners in Big City eggs, while BDE-47 and -99 were dominant in Coastal eggs. In many of the birds that gave multiple eggs over time ("time series"), PBDE patterns changed over time: the high proportions of BDE-209 and higher brominated PBDEs (short half-lives) in young birds contrasted with increasingly higher proportions of BDE-153 (long half-life) and other lower brominated PBDEs as the birds aged. These data are consistent with metabolic debromination of BDE-209 (t(1/2) = 1-2 weeks) to the lower brominated PBDEs, with accumulation over time of BDE-153 (t(1/2) = 3-4 years). In contrast, PCB patterns showed no differences by locations, and did not change over time. Diet (prey birds) may explain the urban PBDE pattern, as the patterns in urban pigeons and peregrines were similar, with high proportions of BDE-209 and the higher-brominated PBDEs. Also, our prey data (feathers from peregrine nests) showed urban peregrines having a higher proportion (>2 fold) of granivorous/opportunistic birds (e.g., "introduced feral" pigeons, mourning doves, starlings) in their diet than coastal peregrines. In summary, these data indicate that BDE-209 exits consumer products as an environmental contaminant to be taken up by wildlife (particularly in urban locations), and undergoes metabolic debromination to the banned lower-brominated PBDEs. High levels of the higher-brominated PBDE congeners, especially in urban locations, permitted accurate measures of relative proportions of homologues in each of the hexa-nona congener classes. Using the major hexa-nona homologues in each of these classes, we propose a pathway for the stepwise, metabolic debromination of BDE-209.

Real-time instrumentation was used to obtain highly resolved time-series concentration profiles for a number of air pollutants. The B-TRAPPED field study was conducted in the residential Sunset Park neighborhood of Brooklyn, NY, USA, in May 2005. The neighborhood contained the Gowanus Expressway (Interstate 278), a major arterial road (4 super(th) Avenue), and residential side streets running perpendicular to the Gowanus Expressway and 4 super(th) Avenue. Synchronized measurements were obtained inside a test house, just outside the test house facade, and along the urban residential street canyon on which the house was located. A trailer containing Federal Reference Method (FRM) and real-time monitors was located next to the Gowanus Expressway to assess the source. Ultrafine particulate matter (PM), PM sub(2.5), nitrogen oxides (NO sub(x)), sulfur dioxide (SO sub(2)), carbon monoxide (CO), carbon dioxide (CO sub(2)), temperature, relative humidity, and wind speed and direction were monitored. Different sampling schemes were devised to focus on dispersion along the street canyon or infiltration into the test house. Results were obtained for ultrafine PM, PM sub(2.5), criteria gases, and wind conditions from sampling schemes focused on street canyon dispersion and infiltration. For comparison, the ultrafine PM and PM sub(2.5) results were compared with an existing data set from the Los Angeles area, and the criteria gas data were compared with measurements from a Vancouver epidemiologic study. Measured ultrafine PM and PM sub(2.5) concentration levels along the residential urban street canyon and at the test house facade in Sunset Park were demonstrated to be comparable to traffic levels at an arterial road and slightly higher than those in a residential area of Los Angeles. Indoor ultrafine PM levels were roughly 3-10 times lower than outdoor levels, depending on the monitor location. CO, NO sub(2), and SO sub(2) levels were shown to be similar to values that produced increased risk of chronic obstructive pulmonary disease hospitalizations in the Vancouver studies.

Densely populated areas may also be targeted for intentional releases of biological or chemical agents because an urban release could result in higher morbidity and mortality from the attack. Since people tend to spend the majority of their time indoors, it is paramount to explore the relationships between outdoor and indoor air quality and, specifically, the time scales that characterize transport of airborne contaminants from outdoors to indoors. In the Brooklyn Traffic Real-Time Ambient Pollutant Penetration and Environmental Dispersion (B-TRAPPED) study, a three-story row house with a flat face and roof and multiple rooms was used to investigate outdoor-to-indoor contaminant time scales. The building was located in the Sunset Park neighborhood of Brooklyn, NY, USA, in the vicinity of a major expressway and a heavily trafficked arterial road. It was found that the building shell has a profound impact on the indoor concentrations. A strong hourly periodicity (see Eisner et al., this issue, DOI: 10.1039/b907132f) in concentration outside the building during the morning "rush hour" was used as evidence to suggest that indoor contaminants originated from outdoor air penetration. Although the indoor concentrations followed a similar pattern, indoor concentrations were found to be more persistent than outdoor concentrations. Stronger persistency is used here to describe the tendency of the indoor concentration to continue to rise even if the outdoor concentration has started to drop, or vice versa. This may be an important factor in assessing negative health risks to inhabitants or first responders. A cross-correlation technique was employed to study the correlation between outdoor and indoor time series. In the high-density housing residential building used in the study, it was found that a long lag time exists (11 min) before indoor and outdoor concentrations reach maximal correlation.

In particular, it addresses selenium (Se) as a bioindicator of susceptibility to harmful effects of Hg exposures and evaluates how Se moderates the toxic effects of Hg in a variety of test animals, emphasizing the importance of these potential effects in fish. A major conclusion of this review is that Hg toxicity risks to animal life cannot be accurately assessed without considering the moderating effects of Se. Therefore, Se:Hg molar ratios and their mathematical inverse are important factors that need to be considered when assessing risks from Hg exposures because exposures are related directly to toxicity outcome. In addition, actual measurement of both beneficial nutrients (e.g., Se, omega-3 fatty acids) and contaminants (e.g., Hg, polychlorinated biphenyls [PCB]) in fish tissue, rather than gross associations between the amounts of fish tissue consumed and changes in child IQ, motor skills, and verbal skill scores, has been recommended by human health effects researchers. This integrated approach will improve accuracy and reliability of environmental risk assessments for fish and fish consumers.

The Environmental Monitoring and Assessment Program (EMAP) is designed to assess the status and trends of ecological resources at different scales. High-resolution remote sensing provides unique capabilities in detecting a variety of features and indicators of environmental health and condition. LIDAR is an airborne scanning laser system that provides data on topography, channel dimensions (width, depth), slope, channel complexity (residual pools, volume, morphometric complexity, hydraulic roughness), riparian vegetation (height and density), dimensions of riparian zone, anthropogenic alterations and disturbances, and channel and riparian interaction. Hyperspectral aerial imagery offers the advantage of high spectral and spatial resolution allowing for the detection and identification of riparian vegetation and natural and anthropogenic features at a resolution not possible with satellite imagery. When combined, or fused, these technologies comprise a powerful geospatial data set for assessing and monitoring lentic and lotic environmental characteristics and condition.

Pollutant dispersion AN - 21274967; 11810530 AB - This article is the second in a two-paper series presenting results from wind tunnel and computational fluid dynamics (CFD) simulations of flow and dispersion in an idealized model urban neighborhood. Pollutant dispersion results are presented and discussed for a model neighborhood that was characterized by regular city blocks of three-story row houses with a single 12-story tower located at the downwind edge of one of these blocks. The tower had three significant effects on pollutant dispersion in the surrounding street canyons: drawing the plume laterally towards the tower, greatly enhancing the vertical dispersion of the plume in the wake of the tower, and significantly decreasing the residence time of pollutants in the wake of the tower. In the wind tunnel, tracer gas released in the avenue lee of the tower, but several blocks away laterally, was pulled towards the tower and lifted in the wake of the tower. The same lateral movement of the pollutant was seen in the next avenue, which was approximately 2.5 tower heights downwind of the tower. The tower also served to ventilate the street canyon directly in its wake more rapidly than the surrounding areas. This was evidenced by CFD simulations of concentration decay where the residence time of pollutants lee of the 12-story tower was found to be less than half the residence time behind a neighboring three-story building. This same phenomenon of rapid vertical dispersion lee of a tower among an array of smaller buildings was also demonstrated in a separate set of wind tunnel experiments using an array of cubical blocks. A similar decrease in the residence time was observed when the height of one block was increased.

Experiments were performed in a street canyon perpendicular to a highway in Brooklyn, NY, USA. Real-time ultrafine PM samplers were positioned on either side of an intersection at multiple locations along a street to collect time-series number concentration data. Meteorology equipment was positioned within the street canyon and at an upstream background site to measure wind speed and direction. Time-series analysis was performed on the PM data to compute a transport velocity along the direction of the street for the cases where background winds were parallel and perpendicular to the street. The data were analyzed for sampler pairs located (1) on opposite sides of the intersection and (2) on the same block. The time-series analysis demonstrated along-street transport, including across the intersection when background winds were parallel to the street canyon and there was minimal transport and no communication across the intersection when background winds were perpendicular to the street canyon. Low but significant values of the cross-correlation function (CCF) underscore the turbulent nature of plume transport along the street canyon. The low correlations suggest that flow switching around corners or traffic-induced turbulence at the intersection may have aided dilution of the PM plume from the highway. This observation supports similar findings in the literature. Furthermore, the time-series analysis methodology applied in this study is introduced as a technique for studying spatiotemporal variation in the urban microscale environment.

In the portion of the study described here, synchronized wind velocity and azimuth as well as particulate matter (PM) concentrations at multiple locations along 33rd Street were used to determine the feasibility of using traffic emissions in a complex urban topography as a sole tracer for studying urban contaminant transport. We demonstrate in this paper that it is possible to link downwind concentrations of contaminants in an urban street canyon to the vehicular traffic cycle using Eigen-frequency analysis. In addition, multivariable circular histograms are used to establish directional frequency maxima for wind velocity and contaminant concentration.

Using continuous real-time total number concentration time-series data measured simultaneously at multiple outdoor and indoor locations, the infiltration time was estimated for various indoor sites by using the cross-correlation analysis method. The effects of meteorological variables on infiltration times were also characterized at given locations. In particular, infiltration time was examined as a function of outdoor mean rooftop wind speed. Outdoor and indoor temperature and relative humidity were also investigated in relation to infiltration times. Our results showed that outdoor wind speed was the dominant meteorological parameter affecting the infiltration rate, but no correlation was found with temperature. The outdoor-indoor PM concentration ratio was found to be significantly different for the first and second floors of the test building. Finally, we determined the effectiveness of a protective shelter-in-place area inside the building by calculating infiltration times into the area. We found that the shelter-in-place area offered some protection against the infiltrating particles because of increased attenuation of the outdoor concentration.

The urban PM transport, dispersion, and infiltration processes were described mathematically in a theoretical model that was constructed to develop the experimental objectives of the B-TRAPPED study. In the study, simultaneous and continuous time-series PM concentration and meteorological data collected at multiple outdoor and indoor monitoring locations were used to characterize both temporal and spatial patterns of the PM concentration movements within microscale distances (<500 m) from the highway. Objectives of the study included (1) characterizing the temporal and spatial PM concentration fluctuation and distribution patterns in the urban street canyon; (2) investigating the effects of urban structures such as a tall building or an intersection on the transport and dispersion of PM; (3) studying the influence of meteorological variables on the transport, dispersion, and infiltration processes; (4) characterizing the relationships between the building parameters and the infiltration mechanisms; (5) establishing a cause-and-effect relationship between outdoor-released PM and indoor PM concentrations and identifying the dominant mechanisms involved in the infiltration process; (6) evaluating the effectiveness of a shelter-in-place area for protection against outdoor-released PM pollutants; and (7) understanding the predominant airflow and pollutant dispersion patterns within the neighborhood using wind tunnel and CFD simulations. The 10 papers in this first set of papers presenting the results from the B-TRAPPED study address these objectives. This paper describes the theoretical background and models representing the interrelated processes of transport, dispersion, and infiltration. The theoretical solution for the relationship between the time-dependent indoor PM concentration and the initial PM concentration at the outdoor source was obtained. The theoretical models and solutions helped us to identify important parameters in the processes of transport, dispersion, and infiltration. The B-TRAPPED study field experiments were then designed to investigate these parameters in the hope of better understanding urban PM pollutant behaviors.

Flow characteristics AN - 21256238; 11810529 AB - Wind tunnel experiments were performed to examine the effect of a tall tower on the flow around an otherwise uniform array of buildings. Additionally, preliminary CFD simulations were run to visualize the flow with more resolution. The model used in both the wind tunnel and CFD studies was designed to simulate an area of Brooklyn, NY, USA, where blocks of residential row houses form a neighborhood bordering a major urban highway. This area was the site of a field study that, along with the work reported here, had the goal of improving the understanding of airflow and dispersion patterns within urban microenvironments. Results reveal that a tall tower has a dramatic effect on the flow in the street canyons in the neighboring blocks, enhancing the exchange between the street canyon flow and the freestream flow aloft. In particular, vertical motion down the windward side and up the leeward side of the tower resulted in strong flows in the lateral street canyons and increased winds in the street canyons in the immediate vicinity of the tower. These phenomena were visible in both the wind tunnel and CFD results, although some minor differences in the flow fields were noted.

Various patterns of spatial and temporal changes in the street canyon PM concentrations were investigated using time-series data of real-time PM concentrations measured during multiple monitoring periods. Concurrent time-series data of local street canyon wind conditions and wind data from the John F. Kennedy (JFK) International Airport National Weather Service (NWS) were used to characterize the effects of various wind conditions on the behavior of street canyon PM concentrations. Our results suggest that wind direction may strongly influence time-averaged mean PM concentration distribution patterns in near-highway urban street canyons. The rooftop-level wind speeds were found to be strongly correlated with the PM concentration fluctuation intensities hi the middle sections of the street blocks. The ambient turbulence generated by shifting local wind directions (angles) showed a good correlation with the PM concentration fluctuation intensities along the entire distance of the first and second street blocks only when the wind angle standard deviations were larger than 30 degrees. Within-canyon turbulent shearing, caused by fluctuating local street canyon wind speeds, showed no correlation with PM concentration fluctuation intensities. The time-averaged mean PM concentration distribution along the longitudinal distances of the street blocks when wind direction was mostly constantly parallel to the street was found to be similar to the distribution pattern for the entire monitoring period when wind direction fluctuated wildly. Finally, we showed that two different PM concentration metrics--time-averaged mean concentration and number of concentration peaks above a certain threshold level--can possibly lead to different assessments of spatial concentration distribution patterns.

This study investigated in utero and/or pre-weaning undernutrition effects on reproductive maturation and senescence in the Sprague-Dawley rat as well as potential intergenerational effects. Pregnant rats were given food ad libitum or at 50% of normal dietary intake throughout pregnancy. Their offspring (control or IUGR) were cross-fostered to control dams with litter sizes of 8 or 16 pups (control and undernourished). Offspring body weights were reduced and onset of male puberty slightly delayed in animals from large postnatal litters. Similar body weight effects were observed in females but there was no difference in the age of vaginal opening. Female reproductive senescence as measured by onset of estrus acyclicity occurred at a younger age in IUGR-8-pup and Control-16-pup groups compared to Control-8-pup or IUGR-16-pup groups. Females were bred to control males and no evidence of adverse reproductive effects was found in any F2 groups. The offspring of the F1 generation did not show an intergenerational effect as documented in humans.

Although methods for estimating detection probabilities are available, many analyses use raw counts and do not correct for detectability. We use a removal model of detection within an N-mixture approach to estimate abundance trends corrected for imperfect detection. We compare the corrected trend estimates to those estimated from raw counts for 16 species using 15 years of monitoring data on three national forests in the western Great Lakes, USA. We also tested the effects of overdispersion by modeling both counts and removal mixtures under three statistical distributions: Poisson, zero-inflated Poisson, and negative binomial. For most species, the removal model produced estimates of detection probability that conformed to expectations. For many species, but not all, estimates of trends were similar regardless of statistical distribution or method of analysis. Within a given combination of likelihood (counts vs. mixtures) and statistical distribution, trends usually differed by both stand type and national forest, with species showing declines in some stand types and increases in others. For three species, Brown Creeper, Yellow-rumped Warbler, and Black-throated Green Warbler, temporal patterns in detectability resulted in substantial differences in estimated trends under the removal mixtures compared to the analysis of raw counts. Overall, we found that the zero-inflated Poisson was the best distribution for our data, although the Poisson or negative binomial performed better for a few species. The similarity in estimated trends that we observed among counts and removal mixtures was probably a result of both experimental design and sampling effort. First, the study was originally designed to avoid confounding observer effects with habitats or time. Second, our time series is relatively long and our sample sizes within years are large.

The magnitudes of the flux estimates were in the range of published results from other micrometeorological mercury fluxes taken above a tall canopy and larger than estimates from flux chambers. The magnitude and direction of the flux were not static during the growing season. There was a significant trend (p < 0.001), from net deposition of TGM in early summer to net evasion in the late summer and early fall before complete senescence. A growing season atmosphere-canopy total mercury (TGM) compensation point during unstable daytime conditions was estimated at background ambient concentrations (1.41 ng m super(-) super(3)). The trend in the seasonal net TGM flux indicates that long term dry deposition monitoring is needed to accurately estimate mercury loading over a forest ecosystem.

One hundred simulations were conducted with fine resolutions and observational constraints, to reproduce spatial and temporal features of observed PM concentrations and to understand the formation mechanism of the episode. Simulated PM concentrations consist of secondary inorganic components, mainly ammonium nitrate, and total carbon in areas with elevated concentrations in the accumulation mode, and consist of mainly dust and sea salt in the coarse mode. Simulated oxidants and nitrate were significantly elevated over the valley, and the latter showed much less amplitude than the former. Simulated PM concentrations were evaluated with observations systematically with spatially and temporally paired method, a more restrictive multivariate method (NMFROC), and a more flexible ''gradient evaluation'' method. The paired evaluation shows that high correlation coefficient (R=} .8) and low fractional error (FE=} .1) could be achieved at stations with elevated 24-h concentration of PM in the accumulation mode in some simulations. The NMFROC method was used to extract useful information from seemingly failed simulations. A ''gradient evaluation'' method is introduced here to extract additional information from simulations. We found that emission reductions of NO sub(x) and AVOC showed similar effects on percentage basis in different areas, and both are more effective than reducing NH sub(3) for abating elevated concentrations of accumulation mode PM in California Central Valley during the winter episode.

Hypoxia is one of the key water quality issues addressed as a result of the above Agreement. This paper summarizes the protection goals and specific criteria intended to achieve those goals for addressing hypoxia. The criteria take into account the variety of Bay habitats and the tendency towards low dissolved oxygen in some areas of the Bay. Stressful dissolved oxygen conditions were characterized for a diverse array of living resources of the Chesapeake Bay by different aquatic habitats: migratory fish spawning and nursery, shallow-water, open-water, deep-water, and deep-channel. The dissolved oxygen criteria derived for each of these habitats are intended to protect against adverse effects on survival, growth, reproduction and behavior. The criteria accommodate both spatial and temporal aspects of low oxygen events, and have been adopted into the Chesapeake Bay states - Maryland, Virginia, and Delaware - and the District of Columbia's water quality standards regulations.

Linking Excess Nutrients, Light, and Fine Bedded Sediments to Impacts on Faunal Assemblages in Headwater Agricultural Streams. Journal of the American Water Resources Association (JAWRA) 45(6):1475-1492. Abstract: Biological impairments in streams are typically defined by regulatory agencies in terms of altered invertebrate or fish assemblages. While nutrients, canopy cover, and sediment fines contribute to these impairments, these stressors are often defined, at least in part, by their impacts on periphyton. Path analysis can extend these assessments to impacts on invertebrates and fish by characterizing the direct and indirect relationships among variables along defined model pathways. With data from headwater tributaries in the Little Miami River, Ohio, we tested models of the impacts of nutrients [total nitrogen (TN), total phosphorus (TP), and the nitrogen to phosphorus (N/P) ratio], the percentage of (%) open canopy, and the % sand and fines on three periphyton metrics [periphytic ash-free dry mass (AFDM), the percent abundance of cyanobacteria (% cyanobacteria), and the percent abundance of Chlorophyta (% Chlorophyta)] and, in turn, on selected invertebrate or fish metrics. Our objective was to develop and evaluate a statistical model that assesses the direct and indirect impacts of excess nutrients on macroinvertebrate and fish in these streams and demonstrate how this approach might be applicable elsewhere. The results suggest indirect pathways for the influences of nutrients, canopy cover, and fine bedded sediments on invertebrates or fish that are mediated by their influences on periphyton. This is in addition to any direct impacts of these stressors on the invertebrate and fish metrics. In most models, all three periphyton metrics increased with % open canopy. Periphytic AFDM increased with TN, while % cyanobacteria decreased. The % cyanobacteria also decreased with % sand and fines, but % Chlorophyta increased. The metrics, percent abundance of (%) three most dominant (macroinvertebrate) taxa, % Trichoptera, and % herbivorous fish all increased with periphytic AFDM, while % climbers, % swimmers, and %Lepomis cyanellus Rafinesque decreased. Lepomis cyanellus is an indicator species, because it is generally common in these streams and relatively tolerant to various common environmental stressors. The % three most dominant macroinvertebrate taxa increased while % Hydropsychidae (Trichoptera) and %L. cyanellus decreased with % cyanobacteria. The % Trichoptera and %L. cyanellus increased with % Chlorophyta. Some macroinvertebrate metrics, such as the % burrowers and number of burrower taxa, did not have any statistically significant relationships with the periphyton metrics but did exhibit a direct pathway with % sand and fines. These analyses illustrate how path analysis can be used to estimate the relationships among the variables in a conceptual model, modify the model, assess the relative importance of different paths, and explore responses resulting from stressors with interacting and indirect impacts.

However, projected climatic changes render this assumption invalid. Here, we summarize general principles for management adaptations that have emerged from a major literature review. These general principles cover many topics including: (1) how to assess climate impacts to ecosystem processes that are key to management goals; (2) using management practices to support ecosystem resilience; (3) converting barriers that may inhibit management responses into opportunities for successful implementation; and (4) promoting flexible decision making that takes into account challenges of scale and thresholds. To date, the literature on management adaptations to climate change has mostly focused on strategies for bolstering the resilience of ecosystems to persist in their current states. Yet in the longer term, it is anticipated that climate change will push certain ecosystems and species beyond their capacity to recover. When managing to support resilience becomes infeasible, adaptation may require more than simply changing management practices-it may require changing management goals and managing transitions to new ecosystem states. After transitions have occurred, management will again support resilience-this time for a new ecosystem state. Thus, successful management of natural resources in the context of climate change will require recognition on the part of managers and decisions makers of the need to cycle between 'managing for resilience' and 'managing for change.'

This study explores the possibility of using single rodent acute toxicity values to predict chemical toxicity to a diversity of wildlife species and estimate hazard levels from modeled species sensitivity distributions (SSD). Interspecies correlation estimation (ICE) models predict toxicity values for untested species using the sensitivity relationship between measured toxicity values of two species. Predicted toxicity values can subsequently populate SSD for application in ecological risk assessments. Laboratory mouse and rat toxicity values were used to estimate toxicity to wildlife and the predicted values then were used to derive SSD hazard dose levels. Toxicity values were predicted within fivefold of measured toxicity values for 78% of ICE models using laboratory rat or mouse toxicity as a surrogate value. Hazard dose levels (HD5) were within fivefold of measured estimates for 72% of SSD developed using laboratory rodent ICE models. Rodents were most often in the least sensitive quartile of species sensitivity distributions, and therefore toxicity values alone may not adequately represent the toxicity to many species of concern without appropriate safety or assessment factors. Laboratory rodent toxicity data offer an additional source of information that can be used to predict hazard levels for wildlife species, and thus offer a starting point for both health and ecological risk assessment.

AN - 66634150; 19660485 AB - We have developed a comprehensive, Bayesian, PBPK model-based analysis of the population toxicokinetics of trichloroethylene (TCE) and its metabolites in mice, rats, and humans, considering a wider range of physiological, chemical, in vitro, and in vivo data than any previously published analysis of TCE. The toxicokinetics of the "population average," its population variability, and their uncertainties are characterized in an approach that strives to be maximally transparent and objective. Estimates of experimental variability and uncertainty were also included in this analysis. The experimental database was expanded to include virtually all available in vivo toxicokinetic data, which permitted, in rats and humans, the specification of separate datasets for model calibration and evaluation. The total combination of these approaches and PBPK analysis provides substantial support for the model predictions. In addition, we feel confident that the approach employed also yields an accurate characterization of the uncertainty in metabolic pathways for which available data were sparse or relatively indirect, such as GSH conjugation and respiratory tract metabolism. Key conclusions from the model predictions include the following: (1) as expected, TCE is substantially metabolized, primarily by oxidation at doses below saturation; (2) GSH conjugation and subsequent bioactivation in humans appear to be 10- to 100-fold greater than previously estimated; and (3) mice had the greatest rate of respiratory tract oxidative metabolism as compared to rats and humans. In a situation such as TCE in which there is large database of studies coupled with complex toxicokinetics, the Bayesian approach provides a systematic method of simultaneously estimating model parameters and characterizing their uncertainty and variability. However, care needs to be taken in its implementation to ensure biological consistency, transparency, and objectivity.

We analysed 86 faecal samples of 53 gliders from 11 locations and obtained 97 observations of 10 gliders feeding at two locations. Pollen of Eucalyptus/Corymbia was present in 70% and Melaleuca in 20% of faecal samples. Indicators of sap feeding were present in 44% of samples and seeds were present in 14% of samples. Invertebrates, mostly moth larvae, were present in 54% of samples. Observations of gliders feeding revealed that the main food types were invertebrates (36% of observations), nectar and pollen (27% of observations) and sap (26% of observations) of five tree species. Differences in the use of the major food types revealed by the two methods of diet analysis partly reflect site-based differences. Qualitatively, the diet was similar to that described in southern Australia, with confirmation that sap may be important at some locations. Our results reveal the contribution that different tree species make to the diet, which should be used to guide habitat restoration for the squirrel glider in this fragmented landscape.

One potential alternative is 2,3,3,3-tetrafluoropropene (HFC-1234yf, also known as HFO-1234yf). We have developed a spatially and temporally resolved inventory of likely future HFC refrigerant emissions from the U.S. vehicle fleet in 2017, considering regular, irregular, servicing, and end-of-life leakages. We estimate the annual leak rate emissions for each leakage category for a projected 2017 U.S. vehicle fleet by state, and spatially apportion these leaks to a 36 km square grid over the continental United States. This projected inventory is a necessary first step in analyzing for potential atmospheric and ecosystem effects, such as ozone and trifluoroacetic acid production, that might result from widespread replacement of HFC-134a with HFC-1234yf.

This information is critical for deciphering the sources and biogeochemical pathways of organic carbon, and thus vital to the understanding of carbon cycling and budgets. Waters of the West Florida Shelf are heavily influenced by many river systems on Florida's Gulf Coast that, to the first order, control CDOM distributions on the shelf. Three storm events during 2004 and 2005 (Hurricane Charley, Hurricane Wilma, and a Winter Storm) profoundly altered the typical distribution of CDOM fluorescence and absorption properties on the Southern West Florida Shelf. Seasonal surveys revealed that changes in the underwater light field as a result of major hurricanes and resuspension events are linked closely with a number of factors prior to a storm's passing such as the presence of persistent blooms, rainfall and discharge. Additionally, storm track and wind direction were found to play a significant role in CDOM signatures. JF - Journal of Geophysical Research. G.

11176669 AB - A fast, rigorous method was developed to maximize the extraction efficacy for ten perfluorocarboxylic acids and perfluorooctanesulfonate from waste-water-treatment sludge and to quantitate using liquid chromatography, tandem-mass spectrometry (LC/MS/MS). First, organic solvents were tested for extraction efficiency, including acetonitrile (ACN), methanol (MeOH), isopropanol (IPA), tetrahydrofuran (THF), and 50/50 ACN/MeOH (v/v). Among the extractants tested, 50/50 ACN/MeOH yielded the best results for our combined criteria of extraction efficacy and solvent-handling convenience. Second, chemical pretreatment prior to solvent extraction was tested with sodium hydroxide (NaOH), potassium hydroxide (KOH), hydrochloric acid (HCl), and potassium persulfate (K sub(2)S sub(2)O sub(8)). Pretreatment with NaOH and HCl effectively recovered additional PFCs from the sludge, but KOH and K sub(2)S sub(2)O sub(8) digestion were less effective than no pretreatment. Third, cleanup methods were investigated with solid-phase extraction using HLB (hydrophilic-lipophilic balanced) and WAX (weak-anion exchange) stationary phases, and with ion-pairing. The HLB stationary phase yielded a slight edge over the other two cleanup strategies in terms of recoverable PFCs and chromatographic separation. Finally, the appropriateness of isotopically labeled PFCs for quantitating unlabeled PFCs using isotopic dilution in complex sludge extracts was evaluated by comparison to results obtained with the standard-addition method. A National Institute of Standards and Technology (NIST) domestic sludge (CRM 2781) was analyzed using our finalized method and compared with previously reported results.

To characterize gene expression profiles predictive of MMA(III) exposure and mode of action of carcinogenesis, skin and papilloma RNA was isolated from K6/ODC mice administered 0, 10, 50, and 100 ppm MMA(III) in their drinking water for 26 weeks. Following RNA processing, the resulting cRNA samples were hybridized to Affymetrix Mouse Genome 430A 2.0 GeneChips registered . Micoarray data were normalized using MAS 5.0 software, and statistically significant genes were determined using a regularized t-test. Significant changes in bZIP transcription factors, MAP kinase signaling, chromatin remodeling, and lipid metabolism gene transcripts were observed following MMA(III) exposure as determined using the Database for Annotation, Visualization and Integrated Discovery 2.1 (DAVID) (Dennis et al., Genome Biol 2003; 4(5):P3). MMA(III) also caused dose-dependent changes in multiple Rho guanine nucleotide triphosphatase (GTPase) and cell cycle related genes as determined by linear regression analyses.

The watershed receives large non-point-source organic waste inputs, mostly from poultry and beef production, with lesser quantities from the rapidly growing human population. The organic wastes from animal agriculture are deposited on nearby pastures and the human wastes are mostly treated with septic systems. We selected the headwater catchments to fall along a gradient of organic waste inputs, and hypothesized that stream dissolved organic matter (DOM) concentrations would increase along this gradient. We used a set of readily obtainable landscape indicators (land use categories, soil carbon content, and soil clay content), factor scores derived from a principal components analysis (PCA) of the landscape indicators, and organic waste input estimates to develop simple empirical models that describe our measured DOM concentrations and elemental ratios (C:N, C:P, and N:P). The models show positive correlations of stream DOC, DON, and DOP concentrations with pasture land cover, and with estimated organic waste inputs, lending support to our hypothesis. Over the entire measurement period, buffer land cover better described mean DOC and DON concentrations [maximum adjusted R super(2) (AdjR super(2)) of 0.86 and 0.90, respectively] whereas the best models for mean DOP concentration and elemental ratios were comprised of both watershed and buffer scale indicators or PCA factor scores (maximum AdjR super(2) ranged from 0.54 to 0.64). Organic waste estimates were also useful DOM descriptors (maximum AdjR super(2) ranged from 0.23 to 0.55), although they were less effective than the landscape indicators. Landscape indicators and organic waste estimates were useful descriptors of DOC concentration variation (maximum AdjR super(2) ranged from 0.22 to 0.77) after grouping the observations by season. Watershed scale indicators were better descriptors during most of the seasons. We conclude that landscape indicators and organic waste input estimates are useful descriptors of DOM concentrations and elemental ratios in watersheds dominated by non-point-source organic matter inputs.

These OTs, principally mono- and di-substituted species of butyltins and methyltins, are a potential health concern because they belong to a broad class of compounds that may be immune, nervous, and reproductive system toxicants. In this article, we develop probability distributions of U.S. population exposures to mixtures of OTs encountered in drinking water transported by PVC pipes. We employed a family of mathematical models to estimate OT leaching rates from PVC pipe as a function of both surface area and time. We then integrated the distribution of estimated leaching rates into an exposure model that estimated the probability distribution of OT concentrations in tap waters and the resulting potential human OT exposures via tap water consumption. Our study results suggest that human OT exposures through tap water consumption are likely to be considerably lower than the World Health Organization (WHO) `safe' long-term concentration in drinking water (150 ug/L) for dibutyltin (DBT)-the most toxic of the OT considered in this article. The 90th percentile average daily dose (ADD) estimate of 0.034 = 2.92 x 10-4 ug/kg day is approximately 120 times lower than the WHO-based ADD for DBT (4.2 ug/kg day).

The empirical study summarised in this article set out to establish whether shortcomings in the planning, management and communication of research commissioned by governmental ministries and agencies are contributing to this ineffectiveness, and to identify how problem areas can be addressed. Specific issues addressed are the planning and management of research, communication of research results to end-users, the roles of interpreters and intermediaries, engagement with stakeholders, and the evaluation of research uptake and impact.

Present water quality guidelines, based on culturable FIB, prevent same day water quality determination, whereas results from qPCR-based approaches are available within several hours. Epidemiological studies at Publicly-Owned Treatment Works (POTW)-impacted freshwater beaches have also indicated correlations between qPCR determined Enterococcus densities and swimming-related illness rates. Similar qPCR assays are now available for several other accepted or emerging FIB groups. This study provides an initial assessment of qPCR estimated Enterococcus, Bacteroidales, E. coli and Clostridium spp. densities in marine water and sand samples collected over one summer from two POTW-impacted recreational beaches. Relative target sequence densities of these organisms in the samples did not correspond with their relative estimated cell densities. These observations were attributable to differences in target sequences recovered from the calibrator cells of the different types of organisms. Comparative cycle threshold (CT) qPCR analyses of whole cell calibrator samples provide a simple and standardizable approach for estimating both total cell and target sequence densities of different types of FIB in water. Cell density estimates obtained by this approach are subject to uncertainty due to potential variability in absolute numbers of target sequences in the target organisms under different physiological or environmental conditions, but still may allow for informative comparisons with the target sequence estimates.

This paper summarizes the results of a pilot-scale study conducted at the U.S. Environmental Protection Agency's (EPA) Test & Evaluation (T&E) Facility in Cincinnati on two ceramic filtration cartridges with pore sizes of 0.05 and 0.01 mu m to evaluate their ability to remove turbidity and microbiological contaminants such as bacteria [Bacillus subtilis ( approximately 1.0 mu m) and Escherichia coli ( approximately 1.4 mu m)], Cryptosporidium oocysts (4-6 mu m), polystyrene latex (PSL) beads (2.85 mu m) (a surrogate for Cryptosporidium), and MS2 bacteriophage ( approximately 0.02 mu m) (a surrogate for enteric viruses). The results demonstrated that the relatively tighter 0.01- mu m cartridge performed better than the 0.05- mu m cartridge in removing all the biological contaminants and surrogates. For turbidity removal, the 0.01- mu m cartridge performed slightly better than the 0.05- mu m cartridge; however, the permeate rate in the 0.01- mu m cartridge reduced rapidly at higher feed water turbidity levels indicating that a tighter membrane should only be used with adequate pretreatment or at a low feed water turbidity to prolong membrane life. Microbiological monitoring was identified as a more sensitive indirect integrity monitoring method than turbidity and particle count monitoring to ensure effective treatment of water by ceramic filtration. Both PSL beads and B. subtilis showed potential as effective surrogates for Cryptosporidium, with B. subtilis showing higher degree of conservatism.

AN - 734112187; 19710361 AB - Atrazine (ATR) has recently been shown to activate the hypothalamic-pituitary-adrenal (HPA) axis in rodents. The current study investigated the effect of ATR and two of its chlorinated metabolites, desisopropylatrazine (DIA) and diamino-s-chlorotriazine (DACT), on the HPA axis in the Long-Evans female rat. A single oral gavage administration of 75 mg/kg ATR or 60.2 mg/kg DIA (a dose equimolar to the applied ATR dose) during the morning of proestrus resulted in significant, acute increases in circulating adrenocorticotropic hormone (ACTH), corticosterone, and progesterone. Oral doses of ATR or DIA were given daily over the course of the 4-day ovarian cycle starting on the day of vaginal estrus, resulted in a similar, dose-responsive activation of the HPA axis. The increase in ACTH, corticosterone, and progesterone by these compounds was of a similar magnitude to that produced by 5-min restraint stress. Single or multiple oral exposures to DACT, on the other hand, did not significantly alter pituitary-adrenal hormone release. These results were observed despite plasma levels of DACT being higher than any other metabolite at the time of hormone measurement. Overall, circulating metabolite concentrations following equimolar dosing were much higher than those observed after ATR administration. Additional studies indicated that the activation of the HPA axis by oral exposure to ATR and DIA was not due simply to the stimulation of gastrointestinal afferents. Similar responses were observed in rats which received an oral dose of ATR following bilateral subdiaphramatic vagotomy and following intravenous administration of DIA in jugular vein catheterized animals. We conclude that ATR and the metabolite DIA significantly activate the HPA axis following oral exposure in the female rat. Activation of this endocrine axis by these chlorotriazines could contribute to the induced changes of female reproductive function reported previously.

AN - 734112163; 19690231 AB - Previously, we reported that atrazine (ATR) alters steroidogenesis in male Wistar rats resulting in elevated serum corticosterone (CORT), progesterone, and estrogens. The increase in CORT indicated that this chlorotriazine herbicide may alter the hypothalamic-pituitary-adrenal axis. This study characterizes the temporal changes in adrenocorticotropic hormone (ACTH), CORT, and P4 in male Wistar rats following a single dose of ATR (0, 5, 50, 100, and 200 mg/kg), simazine (SIM; 188 mg/kg), propazine (PRO; 213 mg/kg), or primary metabolites, deisopropylatrazine (DIA; 4, 10, 40, 80, and 160 mg/kg), deethylatrazine (DEA; 173 mg/kg), and diamino-s-chlorotriazine (DACT; 3.37, 33.7, 67.5, and 135 mg/kg). The maximum dose for each chemical was the molar equivalent of ATR (200 mg/kg). Significant increases in plasma ACTH were observed within 15 min, following exposure to ATR, SIM, PRO, DIA, or DEA. Dose-dependent elevations in CORT and progesterone were also observed at 15 and 30 min post-dosing with these compounds indicating an activation of adrenal steroidogenesis. Measurement of the plasma concentrations of the parent compounds and metabolites confirmed that ATR, SIM, and PRO are rapidly metabolized to DACT. Although DACT had only minimal effects on ACTH and steroid release, dosing with this metabolite resulted in plasma DACT concentrations that were 60-fold greater than that observed following an equimolar dose of ATR and eightfold greater than equimolar doses of DIA or DEA, indicating that DACT is not likely the primary inducer of ACTH release. Thus, the rapid release of ACTH and subsequent activation of adrenal steroidogenesis following a single exposure to ATR, SIM, PRO, DIA, or DEA may reflect chlorotriazine-induced changes at the level of the brain and/or pituitary.

AN - 734080564; 19797001 AB - Polar volatile organic compounds (PVOCs) such as aldehydes and alcohols are byproducts of normal human metabolism and thus are found in blood and exhaled breath. Perturbation of the normal patterns of such metabolites may reflect exposures to environmental stressors, disease state, and human activity. Presented herein is a specific methodology for assaying PVOC biomarkers in exhaled breath condensate (EBC) samples with application to a series of samples from a controlled chamber exposure to dilute diesel exhaust (DE) or to purified air. The collection/analysis method is based on condensation of normal (at rest) exhaled breaths for 10 min (resulting in 1-2 ml of liquid) with subsequent analyte adsorption onto Tenax cartridges followed by thermal desorption and analysis by gas chromatography/mass spectrometry (GC/MS). Analytical data have linearity of response (R(2)>0.98) across a range of 0-160 ng/ml with a detection limit ranging from 0.2 to 7 ng/ml depending on the compound. Statistical analyses of the results of the controlled exposure study indicate that metabolism, as reflected in simple breath-borne oxygenated species, is not affected by exposure to ambient airborne levels of DE. Linear mixed-effects models showed that PVOC biomarker levels are affected by gender and vary significantly among nominally healthy subjects. Differences among PVOCs analyzed in clinic air, purified chamber air, and chamber air containing dilute DE confirm that most of the compounds are likely of endogenous origin as the exogenous exposure levels did not perturb the EBC measurements.

AN - 733812405; 20049117 AB - Epidemiologic studies have reported an association between proximity to highway traffic and increased cardiopulmonary illnesses. We investigated the effect of size-fractionated particulate matter (PM), obtained at different distances from a highway, on acute cardiopulmonary toxicity in mice. We collected PM for 2 weeks in July-August 2006 using a three-stage (ultrafine, < 0.1 microm; fine, 0.1-2.5 microm; coarse, 2.5-10 microm) high-volume impactor at distances of 20 m [near road (NR)] and 275 m [far road (FR)] from an interstate highway in Raleigh, North Carolina. Samples were extracted in methanol, dried, diluted in saline, and then analyzed for chemical constituents. Female CD-1 mice received either 25 or 100 microg of each size fraction via oropharyngeal aspiration. At 4 and 18 hr postexposure, mice were assessed for pulmonary responsiveness to inhaled methacholine, biomarkers of lung injury and inflammation; ex vivo cardiac pathophysiology was assessed at 18 hr only. Overall chemical composition between NR and FR PM was similar, although NR samples comprised larger amounts of PM, endotoxin, and certain metals than did the FR samples. Each PM size fraction showed differences in ratios of major chemical classes. Both NR and FR coarse PM produced significant pulmonary inflammation irrespective of distance, whereas both NR and FR ultrafine PM induced cardiac ischemia-reperfusion injury. On a comparative mass basis, the coarse and ultrafine PM affected the lung and heart, respectively. We observed no significant differences in the overall toxicity end points and chemical makeup between the NR and FR PM. The results suggest that PM of different size-specific chemistry might be associated with different toxicologic mechanisms in cardiac and pulmonary tissues.

AN - 733811956; 20049115 AB - Diverse environmental contaminants, including the plasticizer di(2-ethylhexyl)phthalate (DEHP), are hepatocarcinogenic peroxisome proliferators in rodents. Peroxisome proliferator-activated receptor-alpha (PPAR-alpha) activation and its sequelae have been proposed to constitute a mode of action (MOA) for hepatocarcinogenesis by such agents as a sole causative factor. Further, based on a hypothesized lower sensitivity of humans to this MOA, prior reviews have concluded that rodent hepatocarcinogenesis by PPAR-alpha agonists is irrelevant to human carcinogenic risk. Herein, we review recent studies that experimentally challenge the PPAR-alpha activation MOA hypothesis, providing evidence that DEHP is hepatocarcinogenic in PPAR-alpha-null mice and that the MOA but not hepatocarcinogenesis is evoked by PPAR-alpha activation in a transgenic mouse model. We further examine whether relative potency for PPAR-alpha activation or other steps in the MOA correlates with tumorigenic potency. In addition, for most PPAR-alpha agonists of environmental concern, available data are insufficient to characterize relative human sensitivity to this rodent MOA or to induction of hepatocarcinogenesis. Our review and analyses raise questions about the hypothesized PPAR-alpha activation MOA as a sole explanation for rodent hepatocarcinogenesis by PPAR-alpha agonists and therefore its utility as a primary basis for assessing human carcinogenic risk from the diverse compounds that activate PPAR-alpha. These findings have broad implications for how MOA hypotheses are developed, tested, and applied in human health risk assessment. We discuss alternatives to the current approaches to these key aspects of mechanistic data evaluation.

TY - JOUR T1 - The design and field implementation of the Detroit Exposure and Aerosol Research Study. AN - 733785527; 18941480 AB - The US Environmental Protection Agency recently conducted the Detroit Exposure and Aerosol Research Study (DEARS). The study began in 2004 and involved community, residential, and personal-based measurements of air pollutants targeting 120 participants and their residences. The primary goal of the study was to evaluate and describe the relationship between air toxics, particulate matter (PM), PM constituents, and PM from specific sources measured at a central site monitor with those from the residential and personal locations. The impact of regional, local (point and mobile), and personal sources on pollutant concentrations and the role of physical and human factors that might influence these concentrations were investigated. A combination of active and passive sampling methodologies were employed in the collection of PM mass, criteria gases, semivolatile organics, and volatile organic compound air pollutants among others. Monitoring was conducted in six selected neighborhoods along with one community site using a repeated measure design. Households from each of the selected communities were monitored for 5 consecutive days in the winter and again in the summer. Household, participant and a variety of other surveys were utilized to better understand human and household factors that might affect the impact of ambient-based pollution sources upon personal and residential locations. A randomized recruitment strategy was successful in enrolling nearly 140 participants over the course of the study.

AN - 733600971; 19924974 AB - While breeding tree swallows (Tachycineta bicolor) have been used as biomonitors for freshwater sites, we report the first use of this species to assess contaminant bioaccumulation from estuarine breeding grounds into these aerial insectivores. Eggs and nestlings were collected from nest boxes in a polychlorinated biphenyl (PCB) contaminated estuary, the New Bedford Harbor Superfund site (NBH, Massachusetts, USA), and a reference salt marsh, Fox Hill (FH, Jamestown, Rhode Island, USA). Sediments, eggs, and nestlings were compared on a ng g(-1) wet weight basis for total PCBs and DDE (1,1-bis-(4-chlorophenyl)-2,2-dichloroethene), metabolite of DDT (1,1,1-trichloro-2,2-bis-(p-chlorophenyl)ethane). NBH samples contained high concentrations of PCBs compared to FH for sediment (36,500 and 0.2), eggs (11,200 and 323), and nestlings (16,800 and 26). PCB homologue patterns linked tree swallow contamination to NBH sediment. NBH samples were also contaminated with DDE compared to FH for sediment (207 and 0.9) and nestlings (235 and 30) but not for eggs (526 and 488), suggesting both NBH and nonbreeding ground sources for DDE. The relationships between sediment and tree swallow egg and nestling PCBs were similar to those reported for freshwater sites. Like some highly contaminated freshwater sites, NBH PCB bioaccumulation had little apparent effect on reproductive success.

AN - 67682711; 19775685 AB - A rigorous solid phase extraction/liquid chromatography/tandem mass spectrometry method for the measurement of 10 perfluorinated compounds (PFCs) in fish fillets is described and applied to fillets of bluegill sunfish (Lepomis macrochirus) collected from selected areas of Minnesota and North Carolina. The 4 PFC analytes routinely detected in bluegill fillets were perfluorooctane sulfonate (PFOS), perfluorodecanoic acid (C10), perfluoroundecanoic acid (C11), and perflurododecanoic acid (C12). Measures of method accuracy and precision for these compounds showed that calculated concentrations of PFCs in spiked samples differed by less than 20% from their theoretical values and that the %RSD for repeated measurements was less than 20%. Minnesota samples were collected from areas of the Mississippi River near historical PFC sources, from the St. Croix River as a background site, and from Lake Calhoun, which has no documented PFC sources. PFOS was the most prevalent PFC found in the Minnesota samples, with median concentrations of 47.0-102 ng/g at locations along the Mississippi River, 2.08 ng/g in the St. Croix River, and 275 ng/g in Lake Calhoun. North Carolina samples were collected from two rivers with no known historical PFC sources. PFOS was the predominant analyte in fish taken from the Haw and Deep Rivers, with median concentrations of 30.3 and 62.2 ng/g, respectively. Concentrations of C10, C11, and C12 in NC samples were among the highest reported in the literature, with respective median values of 9.08, 23.9, and 6.60 ng/g in fish from the Haw River and 2.90, 9.15, and 3.46 ng/g in fish from the Deep River. These results suggest that PFC contamination in freshwater fish may not be limited to areas with known historical PFC inputs.

AN - 67676649; 19709749 AB - This paper presents an innovative, quantitative assessment of pollution avoidance attributable to environmental regulation enforced through integrated licensing, using Ireland's pharmaceutical-manufacturing sector as a case study. Emissions data reported by pharmaceutical installations were aggregated into a pollution trend using an Environmental Emissions Index (EEI) based on Lifecycle Assessment methodologies. Complete sectoral emissions data from 2001 to 2007 were extrapolated back to 1995, based on available data. Production volume data were used to derive a sectoral production index, and determine 'no-improvement' emission trends, whilst questionnaire responses from 20 industry representatives were used to quantify the contribution of integrated licensing to emission avoidance relative to these trends. Between 2001 and 2007, there was a 40% absolute reduction in direct pollution from 27 core installations, and 45% pollution avoidance relative to hypothetical 'no-improvement' pollution. It was estimated that environmental regulation avoided 20% of 'no-improvement' pollution, in addition to 25% avoidance under business-as-usual. For specific emissions, avoidance ranged from 14% and 30 kt a(-1) for CO(2) to 88% and 598 t a(-1) for SO(x). Between 1995 and 2007, there was a 59% absolute reduction in direct pollution, and 76% pollution avoidance. Pollution avoidance was dominated by reductions in emissions of VOCs, SO(x) and NO(x) to air, and emissions of heavy metals to water. Pollution avoidance of 35% was attributed to integrated licensing, ranging from between 8% and 2.9 t a(-1) for phosphorus emissions to water to 49% and 3143 t a(-1) for SO(x) emissions to air. Environmental regulation enforced through integrated licensing has been the major driver of substantial pollution avoidance achieved by Ireland's pharmaceutical sector - through emission limit values associated with Best Available Techniques, emissions monitoring and reporting requirements, and performance targets specified in environmental management plans. This compliant sector offers a positive, but not necessarily typical, case study of IPPC effectiveness.

AN - 67675624; 19656569 AB - Human exposure to ambient ozone (O(3)) has been linked to a variety of adverse health effects. The ozone level at a location is contributed by local production, regional transport, and background ozone. This study combines detailed emission inventory, air quality modeling, and census data to investigate the source-receptor relationships between nitrogen oxides (NO(x)) emissions and population exposure to ambient O(3) in 48 states over the continental United States. By removing NO(x) emissions from each state one at a time, we calculate the change in O(3) exposures by examining the difference between the base and the sensitivity simulations. Based on the 49 simulations, we construct state-level and census region-level source-receptor matrices describing the relationships among these states/regions. We find that, for 43 receptor states, cumulative NO(x) emissions from upwind states contribute more to O(3) exposures than the state's own emissions. In-state emissions are responsible for less than 15% of O(3) exposures in 90% of U.S. states. A state's NO(x) emissions can influence 2 to 40 downwind states by at least a 0.1 ppbv change in population-averaged O(3) exposure. The results suggest that the U.S. generally needs a regional strategy to effectively reduce O(3) exposures. But the current regional emission control program in the U.S. is a cap-and-trade program that assumes the marginal damage of every ton of NO(x) is equal. In this study, the average O(3) exposures caused by one ton of NO(x) emissions ranges from -2.0 to 2.3 ppm-people-hours depending on the state. The actual damage caused by one ton of NO(x) emissions varies considerably over space.

12510384 AB - Cryptosporidium is an important waterborne protozoan parasite that can cause severe diarrhea and death in the immunocompromised. The current methods used to monitor for Cryptosporidium oocysts in water are the microscopy-based USEPA methods 1622 and 1623. These methods assess total levels of oocysts in source waters, but do not determine oocyst viability or genotype. Recently, propidium monoazide (PMA) has been used in conjunction with molecular diagnostic tools to identify species and assess the viability of bacteria. The goal of this study was the development of a Cryptosporidium PMA-PCR (CryptoPMA-PCR) assay that includes PMA treatment prior to PCR analysis in order to prevent the amplification of DNA from dead oocysts. The results demonstrated that PMA penetrates only dead oocysts and blocks amplification of their DNA. The CryptoPMA-PCR assay can also specifically detect live oocysts within a mixed population of live and dead oocysts. More importantly, live oocysts, not dead oocysts, were detected in raw waste or surface water samples spiked with Cryptosporidium oocysts. This proof-of-concept study is the first to demonstrate the use of PMA for pre-PCR treatment of Cryptosporidium oocysts.

This BMP, designated Richmond Creek #5 (RC-5), is owned and operated by the New York City Department of Environmental Protection's as part of the Bluebelt program. During monitoring performed in 2003 and 2004, RC-5 was monitored for several water quality parameters including suspended solids (SS), chemical oxygen demand (COD), and phosphorous. Calculated SS loads demonstrated a 61% removal which is in line with the anticipated removals of 55%-57%, however, COD was not being removed from RC-5. Due to visible accumulation of sediment in the forebay and leaves throughout the BMP, maintenance activity was performed in the spring of 2005, to remove the sediment and organic matter (leaves) by vactor truck and physical labor. About four truck loads of sediment and leaf litter, estimated at 35 m super(3) (46 cubic yards), was removed from the site. Monitoring during the fall of 2005 measured the effects of this maintenance activity. The effluent concentrations of COD were significantly less and less variable after maintenance, and calculated influent and effluent COD loading indicated removals. The reduction in COD effluent coincided with drops in effluent phosphorous levels. Effluent SS concentrations were not significantly altered, implying RC-5 still had capacity to remove sediments before maintenance occurred. Indications are that the maintenance activity significantly reduced the COD effluent and may help communities manage phosphorous loadings.

In this paper we conduct a series of numerical simulation experiments to investigate the quantitative significance of climate response uncertainty for economic assessments of climate change. First we characterize climate uncertainty by constructing two probability density functions-a Bayesian model-averaged and a Bayesian updated version-based on a combination of uncertainty ranges for climate sensitivity reported in the scientific literature. Next we estimate the willingness to pay of a representative agent for a range of emissions reduction policies using two simplified economic models. Our results illustrate the potential for large risk premiums in benefits estimates as suggested by the recent theoretical work on climate response uncertainty, and they show that the size and even the sign of the risk premium may depend crucially on how the posterior distribution describing the overall climate sensitivity uncertainty is constructed and on the specific shape of the damage function.

Sodium hypochlorite (bleach) is routinely used in hospitals and health care facilities for surface sterilization; however, the modes of action of bleach on M. bovis BCG and how this organism develops resistance to sodium hypochlorite have not been elucidated. In this study, we performed a global toxicogenomic analysis of the M. bovis response to 2.5mM sodium hypochlorite after 10 and 20min. M. bovis BCG growth was monitored by measuring the quantity of ATP in picomoles produced over a short exposure time (10-60min) to sodium hypochlorite. This study revealed significant regulation of oxidative stress response genes of M. bovis BCG, such as oxidoreductase, peroxidase, heat shock proteins and lipid transport, and metabolism genes. We interpreted this response as a potentially more lethal interplay between fatty acid metabolism, sulfur metabolism, and oxidative stress. Our results also suggest that sodium hypochlorite repressed transcription of genes involved in cell wall synthesis of M. bovis. This study shows that the treatment of M. bovis BCG with bleach inhibits the biosynthesis of outer cell wall mycolic acids and also induces oxidative damage.

We use samples of Carcinus maenas collected over time and space to investigate the genetic patterns underlying the species' initial establishment and spread, and discuss our findings in the context of the species' life history characteristics and demography.Location The central west coast of North America, encompassing California, Oregon, and Washington (USA) and British Columbia (Canada).Methods We collected 1040 total samples from 21 sites representing the major episodes of population establishment and expansion along the west coast of North America. Microsatellite markers were used to assess genetic diversity and structure at different time points in the species' spread, to investigate connectivity between embayments and to estimate both short-term effective population sizes and the number of original founders. Assignment testing was performed to determine the likely source of the introduction.Results Carcinus maenas in western North America likely derived from a single introduction of a small number of founders to San Francisco Bay, CA from the east coast of North America. Throughout its western North American range, the species experiences periodic migration between embayments, resulting in a minor loss of genetic diversity in more recently established populations versus the populations in the area of initial establishment.Main conclusions Low genetic diversity has not precluded the ability of C. maenas to successfully establish and spread on the west coast of North America. An efficient oceanographic transport mechanism combined with highly conducive life history traits are likely the major drivers of C. maenas spread. Evidence for a single introduction underscores the potential utility of early detection and eradication of high-risk invasive species.

These methods were used in the analyses of wastewater samples to investigate their feasibility as alternatives to current fecal indicator bacteria culture methods for predicting the efficiency of viral pathogen removal by standard treatment processes. PMA treatment was effective in preventing qPCR detection of target sequences from non-viable cells. Concentrates of small volume, secondary-treated wastewater samples, collected from a publicly owned treatment works (POTW) under normal operating conditions, had little influence on this effectiveness. Higher levels of total suspended solids, such as those associated with normal primary treatment and all treatment stages during storm flow events, appeared to interfere with PMA effectiveness under the sample preparation conditions employed. During normal operating conditions at three different POTWs, greater reductions were observed in PMA-qPCR detectable target sequences of both Enterococcus and Bacteroidales than in total qPCR detectable sequences. These reductions were not as great as those observed for cultivable fecal indicator bacteria in response to wastewater disinfection. Reductions of PMA-qPCR as well as total qPCR detectable target sequences from enterococci and, to a lesser extent, Bacteroidales correlated well with reductions in infectious viruses during both normal and storm flow operating conditions and therefore may have predictive value in determining the efficiency at which these pathogens are removed.

[Wise LD, Beck SL, Beltrame D, Beyer BK, Chahoud I, Clark RL, Clark R, Druga AM, Fueston MH, Guittin P, Henwood SM, Kimmel CA, Lindstrom P, Palmer AK, Petrere JA, Solomon HM, Yasuda M, York RG. Terminology of developmental abnormalities in common laboratory mammals (version 1). Teratology 1997; 55:249-92] incorporates improvements and enhancements to both content and organization of the terminology, to enable greater flexibility in its application, while maintaining a consistent approach to the description of findings. The revisions are the result of an international collaboration among interested organizations, advised by individual experts and the outcomes of several workshops. The terminology remains organized into tables under the broad categories of external, visceral, and skeletal observations, following the manner in which data are typically collected and recorded in developmental toxicity studies. This arrangement of the tables, as well as other information provided in appendices, is intended to facilitate the process of specimen evaluation at the laboratory bench level. Only the commonly used laboratory mammals (i.e., rats, mice, rabbits) are addressed in the current terminology tables. The inclusion of other species that are used in developmental toxicity testing, such as primates, is considered outside the scope of the present update. Similarly, categorization of findings as, for example, ''malformation'' or ''variation'' remains unaddressed, in accordance with the overall principle that the focus of this document is descriptive terminology and not diagnosis /interpretation. The skeletal terms have been augmented to accommodate cartilage findings.

Water samples were analyzed for Enterococcus densities by quantitative polymerase chain reaction (qPCR) and membrane filtration (MF). This paper investigates the ability of regression models to accurately predict Enterococcus densities above or below a threshold value, using environmental data on a beach-by-beach basis for both methods. The ability to create statistical models for real-time water quality analysis would allow beach managers to make more accurate decisions regarding beach safety. Results from linear regression models indicate that environmental factors explain more of the variability in Enterococcus densities measured by MF than Enterococcus densities measured by qPCR. Results also show that models for both methods did not perform well at predicting occurrences in which water quality levels exceeded a threshold.

In response to the potential impact of the storm on air quality and to assess the exposures to toxic air pollutants of public health concern, the United States Environmental Protection Agency conducted passive monitoring of air toxics for three months, starting in late October 2005 through early February 2006, at up to 18 sites in the New Orleans area affected by Hurricane Katrina. The overall results of the passive ambient monitoring are summarized with the concentrations for the twenty-nine observed volatile organic chemicals, which include benzene, toluene, ethylbenzene, and xylenes, and the measured concentrations are compared with available health-based screening levels. The results of passive monitoring are also compared with those of the collocated canister sampling at one of the sites. The overall results showed that the outdoor levels of atmospheric volatile organic chemcals in the post-Katrina New Orleans area were very low and far below the available screening levels. The results also confirm the effectiveness of passive monitoring in a large geographical area where conventional methods are not feasible, electrical power is not available, and the need for sampling is urgent, as in the aftermath of natural disasters and other catastrophes.

Cross comparison studies in Racine, WI, USA evaluated QPCR against agar-based (US EPA Method 1600) and defined substrate (IDEXX Colilert-18 super(()R)) methods for the detection and quantification of Escherichia coli and enterococci in a variety of aqueous environments (wastewater, stormwater, and surface water). Regulatory outcomes were also compared based on choice of indicator and method. Positive correlation was seen between QPCR cell equivalents and viable cells through the wastewater treatment process and in all surface water samples (river or freshwater bathing beach) but not in direct stormwater discharge. For surface water samples, correlation improved with the application of a site-specific corrective factor, with regulatory action correctly predicted 98% of the time at bathing beaches. This study suggests the potential utility of QPCR for certain water quality monitoring applications.

Of the 95 water bodies surveyed, 85 had oxygen levels sufficient to support aquatic life. This corresponds to a surface area of 3125km super(2) or 99.4% of the total area assessed. Ten water bodies, representing a surface area of 20.2km super(2), were deficient in oxygen but still capable of supporting most aquatic life. No evidence of hypoxia (<2.0mg/l O sub(2)) or anoxia (<0.2mg/l O sub(2)) was found. Dissolved oxygen conditions in a number of estuaries continue to improve, probably due to improved municipal waste water treatment. The implementation of measures contained in both the Nitrates and Urban Waste Water Treatment Directives, together with those of the Water Framework Directive, should ensure areas of oxygen deficiency are eliminated from Irish waters.

Thirty-minute samples were collected at eight locations, ranging from approximately 10-100 m perpendicular from the roadway. The highest concentrations of VOCs were generally measured closest to the roadway, and concentrations decreased exponentially with increasing distance from the roadway. The highest mean concentration for individual VOCs were for ethylene (3.10 ppbv) (mean concentration at x = 13 m), propane (2.27 ppbv), ethane (1.91 ppbv), isopentane (1.54 ppbv), toluene (0.95 ppbv), and n-butane (0.89 ppbv). Concentrations at the nearest roadway location (x = 13 m) were generally between 2.0 and 1.5 times those from the farthest roadway location (x = 92 m). The data were apportioned into four source categories using the EPA Chemical Mass Balance Model (CMB8.2): motor vehicle exhaust, compressed natural gas, propane gas, and evaporative gasoline. The majority of the VOCs resulted from motor vehicle exhaust (67 +/- 12%) (% of total VOC at x = 13 m +/- S.D.).

Ten irrigation offtakes at six farms were monitored over a period of two years during the rehabilitation process. Full rehabilitation consisted of improved inlet structures, flow metering, elimination of water leaks, laser levelling of paddocks, and construction of re-use systems to recycle excess surface irrigation runoff. Partial rehabilitation consisted of the same improvements with the exception of the re-use system. The mean water use per watering of 0.61+/-0.08Ml/ha for the fully rehabilitated farm was approximately one third of that for non-rehabilitated farms (1.89+/-0.15Ml/ha) and two thirds of that for partially rehabilitated farms (0.99+ /-0.07Ml/ha). These differences were statistically significant at the 95% confidence level. A large improvement in efficiency of water use was achieved by upgraded water delivery infrastructure and laser levelling of paddocks. Considerable improvement in water use efficiency was also gained, however, only by installation of re-use systems. It is expected that the overall rehabilitation of irrigation infrastructure will result in a significant reduction of water extracted from the river for flood irrigation in this region. Further longer term monitoring is required to confirm this.

We investigated linkages between landscapes and assemblages in 31 wadeable Piedmont streams in the Etowah River basin in northern Georgia (USA). Our objectives were to identify the indicators of macroinvertebrate and fish integrity from a large set of best land cover (n=45), geomorphology (n=115), and water quality (n=12) variables, and to evaluate the potential for variables measured with minimal cost and effort to effectively predict biotic integrity. Macroinvertebrate descriptors were better predicted by land cover whereas fish descriptors were better predicted by geomorphology. Water quality variables demonstrated moderate levels of predictive power for biotic descriptors. Macroinvertebrate descriptors were best predicted by urban cover (-), conductivity (-), fines in riffles (-), and local relief (+). Fish descriptors were best predicted by embeddedness (-), turbidity (-), slope (+), and forest cover (+). We used multiple linear regression modeling to predict descriptors using three independent variable sets that varied in difficulty of data collection. ''Full'' models included a full range of geomorphic, water quality and landscape variables regardless of the intensity of data collection efforts. ''Reduced'' models included GIS-derived variables describing catchment morphometry and land use as well as variables easily collected in the field with minimal cost and effort. ''Simple'' models only included GIS-derived variables. Full models explained 63-81% of the variation among descriptors, indicating strong relationships between landscape properties and biotic assemblages across our sites. Reduced and simple models were weaker, explaining 48-79% and 42-79%, respectively, of the variance among descriptors. Considering the difference in predictive power among these model sets, we recommend a tiered approach to variable selection and model development depending upon management goals. GIS variables are simple and inexpensive to collect, and a GIS-based modeling approach would be appropriate for goals such as site screening (e.g., identification of reference streams). As management goals become more complex (e.g., long-term monitoring programs), additional, easily collected field variables (e.g., embeddedness) should be included. Finally, labor-intensive variables (e.g., nutrients and fines in sediments) could be added to meet complex management goals such as restoration of impaired streams or mechanistic studies of land use effects on stream ecosystems.

To determine if benthic diatoms could be used as a multi-season biological indicator of wetland condition in isolated forested wetlands of Florida, USA, 11 wetlands were sampled twice during a 5-month period, once when dry, then again when hydrated. Sites sampled when dry had significantly higher diatom taxa richness at genus and species levels. Non-metric multidimensional scaling and multiple response permutation process analyses resulted in no obvious or significant wet/dry grouping of species or genus level abundance data. Five of seven diatom metrics of the Florida Wetland Condition Index (FWCI) for depressional forested wetlands were significantly linearly correlated (p<0.05), while only one of seven metrics (a dissolved oxygen indicator) had a significantly different mean in paired t-test analyses. The final FWCI was significantly correlated (Pearson's r=0.85, p<0.001) between wet and dry sites, and no difference was found in mean FWCI score between wet and dry sites (t=-1.98, p=0.076), suggesting that with additional research, benthic diatoms may be used to monitor and assess wetland condition regardless of season or site hydrologic conditions.

Global climate change is likely to impact plants and animals, as well as microorganisms. The World Health Organization, U.S. Environmental Protection Agency, U.S. Department of Agriculture, U.S. Department of Health and Human Services, and the Intergovernmental Panel on Climate Change cite increased allergic reactions due to climate change as a growing concern. Monitoring of indoor and ambient particulate matter (PM) and the characterization of the content for biological aerosol concentrations has not been extensively performed. Samples from urban and rural North Carolina (NC), and Denver (CO), were collected and analyzed as the goal of this research. A study of PM sub(1) sub(0) (<10 km in aerodynamic diameter) and PM sub(2) sub(.) sub(5) (<2.5 km in aerodynamic diameter) fractions of ambient bioaerosols was undertaken for a six month period to evaluate the potential for long-term concentrations. These airborne bioaerosols can induce irritational, allergic, infectious, and chemical responses in exposed individuals. Three separate sites were monitored, samples were collected and analyzed for mass and biological content (endotoxins, (1,3)-b-d-glucan and protein). Concentrations of these bioaerosols were reported as a function of PM size fraction, mass and volume of air sampled. The results indicated that higher concentrations of biologicals were present in PM sub(1) sub(0) than were present in PM sub(2) sub(.) sub(5), except when near-roadway conditions existed. This study provides the characterization of ambient bioaerosol concentrations in a variety of areas and conditions.

The modeled domain possesses local-scale velocities, reaction rates and transverse dispersion coefficients that are functions of an underlying heterogeneity variate representing one or more controlling biophysical attributes, for example, reactive surface area (submerged plant) density. Reaction rate coefficients are treated as related to local velocities in an inverse square fashion via their mutual dependence upon the variate. The study focuses on the solution for the steady-state case with constant inlet concentration. Results compare well with exact solutions developed for laterally-bounded systems in which the heterogeneity is represented explicitly. Employing the bicontinuum analogue of a second-order model, an expression for an effective longitudinal dispersion coefficient as a function of travel distance is developed using the method of moments. The result provides insights into the behavior of concentration as transverse mixing drives the system asymptotically toward Fickian longitudinal dispersion. The model may represent an improvement over other approaches for characterizing treatment wetland performance because it accounts for evolving shear flow dispersion, and because parameters are few in number, physically based, and invariant with mean velocity.

When simulating barrier performance, numerous isotherm expressions are available for relating aqueous and sorbed concentrations. However, isotherm selection is non-trivial because alternative expressions may yield comparable fits to experimental data. Additionally, concentration data collected for parameter fitting is often outside the range of concentrations relevant to simulating barrier performance. This incompatibility necessitates extrapolation of isotherm behavior during simulation-optimization. Consequently, equally plausible isotherms may predict significantly different barrier performance. Numerical experiments involving organic contaminants were performed to examine the influence of isotherm selection and extrapolation on optimal barrier design. Ten isotherms were calibrated to existing experimental data and evaluated using information-theoretic selection criteria. When incorporated into simulation-optimization, extrapolation effects were clearly evident and optimal designs varied according to the chosen isotherm. To ensure robust barrier design in the presence of such variability, a simple methodology is proposed that utilizes a piecewise-minimum isotherm concept. By favoring plausible isotherms that predict the least amount of sorption, the methodology encourages conservative barrier design while respecting available data.

In this study, the impact of three photochemical mechanisms (CB4, CB05, SAPRC-99) on the Eta-Community Multiscale Air Quality (CMAQ) model's forecast performance for O sub(3), and its related precursors has been assessed over the eastern United States with the observations obtained by aircraft (NOAA P-3 and NASA DC-8) flights, ship and two surface networks (AIRNow and AIRMAP) during the 2004 International Consortium for Atmospheric Research on Transport and Transformation (ICARTT) study. The results at the AIRNow surface sites show that for the observed O sub(3) greater than or equal to 75 ppb, CB05 has the best performance with the normalized mean bias (NMB) of 3.9%, followed by CB4 (NMB=− 5.7%) and SAPRC-99 (NMB=10.6%), whereas CB4 has the best performance with the least overestimation for the observed O sub(3)<75 ppb. On the basis of comparisons with aircraft P-3 measurements, there were consistent overestimations of O sub(3), NO sub(z), PAN and NO sub(y) and consistent underestimations of CO, HNO sub(3), NO sub(2), NO, SO sub(2) and terpenes for all three mechanisms although the NMB values for each species and mechanisms were different. The results of aircraft DC-8 show that CB05 predicts the H sub(2)O sub(2) mixing ratios most closely to the observations (NMB=10.8%), whereas CB4 and SAPRC-99 overestimated (NMB=74.7%) and underestimated (NMB=− 25.5%) H sub(2)O sub(2) significantly, respectively. For different air mass flows over the Gulf of Maine on the basis of the ship data, the three mechanisms have relatively better performance for O sub(3), isoprene and SO sub(2) for the clean marine or continental flows but relatively better performance for CO, NO sub(2) and NO for southwest/west offshore flows. The results of the O sub(3)-NO sub(z) slope over the ocean indicate that SAPRC-99 has the highest upper limits of the ozone production efficiency ( epsilon sub(N)) (5.8), followed by CB05 (4.5) and CB4 (4.0) although they are much lower than that inferred from the observation (11.8), being consistent with the fact that on average, SAPRC-99 produces the highest O sub(3), followed by CB05 and CB4, across all O sub(3) mixing ratio ranges.

13301128 AB - Few quantitative structure-activity relationship (QSAR) studies have successfully modeled large, diverse rodent toxicity end points. In this study, a comprehensive data set of 7385 compounds with their most conservative lethal dose (LD50) values has been compiled. A combinatorial QSAR approach has been employed to develop robust and predictive models of acute toxicity in rats caused by oral exposure to chemicals. To enable fair comparison between the predictive power of models generated in this study versus a commercial toxicity predictor, TOPKAT (Toxicity Prediction by Komputer Assisted Technology), a modeling subset of the entire data set was selected that included all 3472 compounds used in TOPKAT's training set. The remaining 3913 compounds, which were not present in the TOPKAT training set, were used as the external validation set. QSAR models of five different types were developed for the modeling set. The prediction accuracy for the external validation set was estimated by determination coefficient R2 of linear regression between actual and predicted LD50 values. The use of the applicability domain threshold implemented in most models generally improved the external prediction accuracy but expectedly led to the decrease in chemical space coverage; depending on the applicability domain threshold, R2 ranged from 0.24 to 0.70. Ultimately, several consensus models were developed by averaging the predicted LD50 for every compound using all five models. The consensus models afforded higher prediction accuracy for the external validation data set with the higher coverage as compared to individual constituent models. The validated consensus LD50 models developed in this study can be used as reliable computational predictors of in vivo acute toxicity.

11087721 AB - The current study evaluates Pd/Mg performance for 2-chlorobiphenyl (2-CB) dechlorination in the presence of naturally abundant anions such as sulfate, chloride, nitrate, hydroxide and carbonates and organic solvents that are used for ex-situ PCB extraction or may accompany PCB contamination. While studies abound on the effect of these species on corrosion rates of pure Mg, literature on the behavior of Mg galvanically coupled with Pd remains limited making their investigation necessary. We also provide insights on the effect of initial PCB concentration and system pH on 2-CB dechlorination rates. Among anions studied, especially interesting results were noted for nitrate, bicarbonate and the sodium salt of humic acid. NO sub(3) super(-) underwent reduction to NH sub(4) super(+) thereby competing for electrons and consequently lowering 2-CB dechlorination rate. HCO sub(3) super(-) significantly enhanced 2-CB dechlorination rates by serving as a proton donor. Humic acid also showed faster dechlorination rates, probably by acting as an electron shuttle to the PCB. Only OH super(-) produced significant impairment Pd/Mg reactivity systems. While ethanol and acetone both led to reduced dechlorination rates through reduced hydrogen production and increased affinity of 2-CB for the liquid phase, acetone lowered rates further by undergoing reduction to 2-propanol. 2-CB dechlorination at high solvent concentrations and in the presence of common anions highlights robustness of Pd/Mg systems and suggests they will fare comparably to their bench-scale performance in presence of interferences expected in natural systems.

AN - 734143604; 19921915 AB - Biomonitoring is a valuable tool for identifying exposures to chemicals that pose potential harm to human health. However, to date there has been little published on ways to evaluate the relative public health significance of biomonitoring data for different chemicals and even less on cumulative assessment of multiple chemicals. The objectives of our study are to develop a methodology for a health risk interpretation of biomonitoring data and to apply it using NHANES 1999-2002 body burden data fororganophosphorus (OP) pesticides. OP pesticides present a particularly challenging case given the nonspecificity of manymetabolites monitored through NHANES. We back-calculate OP pesticide exposures from urinary metabolite data and compare cumulative dose estimates with available toxicity information for a common mechanism of action (brain cholinesterase inhibition) using data from U.S. EPA. Our results suggest that approximately 40% of children in the United States may have had insufficient margins of exposure (MOEs) for neurological impacts from cumulative exposures to OP pesticides (MOE less than 1000). Limitations include uncertainty related to assumptions about likely precursor pesticide compounds of the urinary metabolites, sources of exposure, and intraindividual and temporal variability.

AN - 734142977; 19921888 AB - Secondary organic carbon (SOC) concentrations in steady-state aerosol were measured in a series of alpha-pinene/NOx and one series of beta-caryophyllene/NOx irradiation experiments. The acidity of the inorganic seed aerosol was varied while the hydrocarbon and NOx concentrations were held constant in each series of experiments. Measurements were made for acidity levels and SOC concentrations much closer to ambient levels than had been previously achieved for alpha-pinene, while there are no previous measurements for SOC increases due to acidity for beta-caryophyllene. The observed enhancement in SOC concentration linearly increases with the measured hydrogen ion concentration in air for each system. For the conditions of these studies, SOC increased by 0.04% per nmol H+ m(-3) for alpha-pinene under two conditions where the organic carbon concentration differed by a factor of 5. For alpha-pinene, this level of response to acidic aerosol was a factor of 8 lower than was reported by Surratt et al. for similar series of experiments for SOC from the photooxidation of isoprene/NOx mixtures. By contrast, SOC from beta-caryophyllene showed an increase of 0.22% per nmol H+ m(-3), roughly two-thirds of the response in the isoprene system. Mass fractions for SOC particle-phase tracers for alpha-pinene decreased slightly with increasing aerosol acidity, although remaining within previously stated uncertainties. Below 200 nmol H+ m(-3), the mass fraction of beta-caryophyllenic acid, the only identified tracer for beta-caryophyllene SOC, was constant although beta-caryophyllenic acid showed a substantial decrease for acidities greater than 400 nmol H+ m(-3).

AN - 734054050; 19647287 AB - Scientific reports concerning chemical and microbiological contaminant levels of rainwater runoff from rooftop collection in both urban and rural areas are reviewed. This alternative source of water has been documented to often contain substantial amounts of contaminants. Studies describing levels of heavy metal contamination specific to runoff from rooftop catchment areas containing exposed metal surfaces are discussed. Depending upon the intended use, scientific evidence is also accumulating that various treatments and disinfections will be required prior to release of roof-runoff water either into surface waters or for more direct consumer usage. For microbial contamination, current proposed standards and guidelines regarding this type of water source are shown to vary widely worldwide. Scientific literature reveals a lack of clarity regarding water quality guidelines and health related standards for certain types of rooftop runoff. Studies suggests that rainwater collection systems which are properly designed, maintained, and treated may provide a valuable supplement to existing water supplies by reducing demand on community water supplies/infrastructure costs, enhancing effective management of storm water runoff, and increasing restoration of underground reservoirs through controlled infiltration.

Water is injected by using a syringe into a high-temperature carbon reactor and converted into H2 and CO, which are separated by gas chromatography (GC) and carried by helium to the isotope ratio mass spectrometer for hydrogen and oxygen isotope analysis. A series of experiments was conducted to evaluate several issues such as sample size, temperature and memory effects. The 2H and 18O values in multiple water standards changed consistently as the reactor temperature increased from 1150 to 1480DGC. The 18O in water can be measured at a lower temperature (e.g. 1150DGC) although the precision was relatively poor at temperatures <1300DGC. Memory effects exist for 2H and 18O between two waters, and can be reduced (to <1%) with proper measures. The injection of different amounts of water may affect the isotope ratio results. For example, in contrast to small injections (100 nL or less) from small syringes (e.g. 1.2 mL), large injections (1 mL or more) from larger syringes (e.g. 10 mL) with dilution produced asymmetric peaks and shifts of isotope ratios, e.g. 4 for 2H and 0.4 for 18O, probably resulting from isotope fractionation during dilution via the ConFlo interface. This method can be used to analyze nanoliter samples of water (e.g. 30 nL) with good precision of 0.5 for 2H and 0.1 for 18O.

Co-located with the Libby vermiculite deposit is a deposit of amphibole asbestos ("Libby Amphibole" or "LA") which is composed of a number of related mineral types, most commonly winchite and richterite, but also tremolite, actinolite, and magnesioriebeckite. Open-pit mining, milling, and processing operations at the Libby Mine resulted in the release of vermiculite and LA to the environment, which, coupled with multiple environmental transport pathways, has resulted in extensive non-occupational inhalation exposure to LA among the residents of Libby via a number of exposure pathways. Adverse health effects have been reported in Libby residents having no occupational exposure to LA-contaminated vermiculite. General non-occupational exposure pathways potentially contributing to the cumulative exposure of Libby residents include 1) disturbance of gross product or waste material, 2) outdoor ambient air, 3) outdoor air associated with the disturbance of contaminated soils or other contaminated media, and 4) indoor air. Early actions implemented by the US Environmental Protection Agency (EPA) targeted the removal of gross vermiculite product and waste materials, resulting in the elimination or significant reduction of related exposures. Subsequent EPA exposure pathway investigations have focused on quantification of remaining LA levels in outdoor ambient air, and, using activity-based sampling methods, quantification of LA levels in indoor air and outdoor air associated with the disturbance of contaminated soils. Data analysis reveals variable exposure levels associated with season and intensity of disturbance. Cumulative exposures vary depending on exposure parameters, but outdoor air associated with disturbance of contaminated soils consistently represents a major exposure pathway for Libby residents.

The slide contains elevated concentrations of chrysotile asbestos and this material is being deposited into Swift Creek and the Sumas River. Approximately 150,000 cubic yards of material moves into the creek annually and this is expected to continue for the next 400-600 years. Over the past several decades, portions of Swift Creek were dredged to prevent flooding of roads and adjacent agricultural land. During this time, dredged materials were removed by private interests and landowners for use as fill material in construction projects, road bed material, and other purposes. EPA used the draft Framework for Investigation of Asbestos-Contaminated Superfund Sites to support the investigation approach used at the site. Based on initial sampling of the dredged materials by PLM and opportunistic sampling of personnel in the field, EPA proceeded to activity-based sampling in the vicinity of Swift Creek. Based on these results, EPA restricted the practice of removing dredged materials as has been done in the past because of concerns about exposures to asbestos in this material. Flooding in January 2009 resulted in large quantities of sediment to be deposited onto upland areas, including residential properties and farm land. This flooding occurred not just in Swift Creek but further downstream in the Sumas River. Sampling of this upland soil (maximum of 33%), bank sediment (maximum of 23%), and surface water (maximum of 879 MFL) in May 2009 indicated chrysotile concentrations that were much higher than anticipated. This talk will focus on the framework for EPA's site investigation efforts, the recent sampling results, and planned next steps for this extremely complex situation. EPA is working cooperatively with the local residents, Whatcom County, and other stakeholders to look for creative solutions to managing the large volume of asbestos-laden material that flows into this system annually.

Global climate models suggest that in the future Puerto Rico and other small islands in the Caribbean will experience changes in rainfall seasonality. It is anticipated that water demands during low-rainfall periods may not be met, and an overall increase in river discharge due to greater amounts of rainfall during wet periods will cause increased damage from flooding and landslides. Land derived sources of sediment and nutrients carried to the marine environment by streams may also increase significantly. Changes in stream flow due to climate change may have profound effects on the downstream production of ecosystem services provided by the marine environment. Global climate models cannot predict the site specific changes in rainfall. However, site specific rainfall data is precisely what is needed in order to assess the potential localized impacts of increased stream flow on reefs and other benthic communities providing essential ecosystem services to island populations. The Bryson Macrophysical Climate Model (MCM) was used to model average monthly temperature, rainfall and its seasonality, and river and sediment discharge for nine USGS gauging stations in Puerto Rico for the past 14,000 years. Temperature and rainfall was calibrated to NOAA HCDN 1961-1990 climate normals. River and sediment discharge was calibrated to USGS gauging station data downloaded from their website. We provide an example from one of our modeled river basins, of how site specific climate scenarios may be developed from MCM output. Hydrologic models such as SWAT, SEDMOD/RUSLE, or AnnAGNPS use daily rainfall data as model input. We chose the wettest and driest years (highest and lowest rainfall years) from the MCM results for the Guanajibo River near Hormigueros. As these data are monthly averages, we used the ratio of average daily rainfall to total monthly rainfall for the 30 year climate normals to derive daily rainfall datasets for use in hydrologic models. Stream and sediment discharge for the basin was modeled using modern rainfall data and compared to model runs using the derived rainfall data (wet and dry scenarios).

Nevertheless, little information is available regarding the effects of low-dose irradiations protracted over time. We used oligomicroarrays to identify the genes that are transcriptionally regulated by persistent exposure to extremely low doses of ionizing radiation in 28 exposed professionals (mean cumulative effective dose plus or minus SD, 19 plus or minus 38 mSv) compared with a matched sample of nonexposed subjects. We identified 256 modulated genes from peripheral blood mononuclear cells profiles, and the main biological processes we found were DNA packaging and mitochondrial electron transport NADH to ubiquinone. Next we investigated whether a different pattern existed when only 22 exposed subjects with accumulated doses >2.5 mSv, a threshold corresponding to the natural background radiation in Italy per year, and mean equal to 25 plus or minus 41 mSv were used. In addition to DNA packaging and NADH dehydrogenase function, the analysis of the higher-exposed subgroup revealed a significant modulation of ion homeostasis and programmed cell death as well. The changes in gene expression that we found suggest different mechanisms from those involved in high-dose studies that may help to define new biomarkers of radiation exposure for accumulated doses below 25 mSv.

Overall ecosystems could often survive by migrating inland, if adjacent lands remained vacant. On the basis of 131 state and local land use plans, we estimate that almost 60% of the land below 1 m along the US Atlantic coast is expected to be developed and thus unavailable for the inland migration of wetlands. Less than 10% of the land below 1 m has been set aside for conservation. Environmental regulators routinely grant permits for shore protection structures (which block wetland migration) on the basis of a federal finding that these structures have no cumulative environmental impact. Our results suggest that shore protection does have a cumulative impact.

Groundwater flows from seeps to pooled springs at 0.010) among other treatment methods for trapped excess air during groundwater infiltration. Calculated mean recharge air temperatures (MRAT) range from 3.9 + or - 1.0 degrees C to 12.4 + or - 0.6 degrees C. About 17% of the NGT's indicate some past air temperatures to be warmer during the Holocene than present climate trends in the region. Apparent ages of recharge events that equilibrated with these surface air temperatures were calculated from cosmogenic (super 39) Ar, (super 14) C, and fissiogenic (super 85) Kr, (super 3) H, and its progeny (super 3) H- (super 3) He. The multi-tracer ages of these springs record recharge events from 5 + or - 3 yr BP ( (super 85) Kr) to 8510 + or - 420 yr BP ( (super 14) C). Fourier transform time-series modeling supports at least two pronounced regional warming trends with significant centennial-scale variability during the Holocene. Where decadal variability can be discerned among the NGT proxies, its past millennium variability exceeds that observed from the most recent half-century of weather instrument records within subalpine areas of the Olympic Peninsula.

In general, groundwaters from unconsolidated deposits and sedimentary rocks had lower average radon levels (ranging from 223 to 284 pCi/L) than metamorphic and igneous rocks (ranging from 268 to 5,820 pCi/L), which is consistent with similar investigations that have found the highest radon levels in groundwater originated from crystalline-rock aquifers which typically contain relatively high amounts of uranium (PA DEP, 2008; DeSimone, 2009). The MCL of 300 pCi/L and proposed alternative MCL of 4,000 pCi/L for states or water systems that implement a multimedia mitigation plan for radon are used as guidelines to evaluate human health risks of radon in source water supplies. The majority of groundwater samples from unconsolidated deposits contained radon levels below 300 pCi/L (66%); conversely, water samples with radon levels below 300 pCi/L were primarily from unconsolidated deposits (57%). Samples exceeding 300 pCi/L were found in each lithology group, with the exception of low/med/high grade metamorphic rock basalt (with only one sample). Of 47 groundwater samples, only four samples exceeded 4,000 pCi/L, all originating from igneous and metamorphic rocks. Overall, the statistical analysis indicates that the final predictive model correlates with radon levels greater than 900 pCi/L with a R (super 2) value of 98%. At lower radon levels, there is greater scattering about the reference line indicating a decreased predictability of radon in groundwater supplies used for drinking water. Based on GIS mapping, there is only limited spatial correlation within EPA Region III indicating insufficient data to accurately contour radon levels across the region (most likely due to the limited number of sites and relatively large scale). However, there is a relationship between predicted indoor air screening levels and radon levels in groundwater. More specifically, radon levels in source water > or = 4,000 pCi/L are strongly related to predicted indoor air screening levels >4 pCi/L and subsequently geologic faulting in the region.

Meadow complexes occur in mountain drainages and consist of discrete parcels of land up to several hectares in area that are characterized by high water tables and that primarily support willows, wetland grasses and sedges. Although these meadow complexes make up less than 1% of the landscape by area, they play a very important role ecologically in terms of the numbers of endemic and migratory species that rely on them. Because meadow complexes are both sparse and ecologically valuable, it is important for land managers to understand the natural controls on their distribution for proper land management. Meadows exist only in locations where the groundwater table remains close to the surface throughout the summer. Water can be supplied to wet meadows from several sources occurring either singularly or in combination. Water sources may include: (1) bedrock-source groundwater springs that derive their recharge within the drainage basin, (2) bedrock-source regional scale groundwater springs that transfer water from one watershed to another, and (3) alluvial-fill-source water moving down valley through the valley-fill sediments. Although groundwater discharge and high water tables are essential for meadows, groundwater discharge alone is insufficient to form and sustain a meadow. Meadows also require circumstances in the geologic, geomorphic, and sedimentologic architecture of the site that causes the down-valley flux of groundwater to be detained so that groundwater levels rise to the surface. Constrictions most commonly occur where bedrock valleys narrow and alluvium from tributary valleys accumulate in the axial valley. In many cases, these side valleys produce well-defined alluvial fans that prograde into or across the axial valley. This setting leads to a complex stratigraphic package, including fine-grained materials, that create the conditions necessary to detain groundwater and promote shallow groundwater tables.

Our research area was to determine if road salts in the surface and ground waters were detrimental to the stream channel restoration. The upstream reach (UP), above the Baltimore I-695 Beltway, was restored in 1998/99, with post-restoration monitoring. The downstream reach (DOWN) was restored in 2004/05 with pre- and post-restoration monitoring. Stream gauges and piezometers were installed in the stream channel and floodplain along multiple transects in both reaches. Statistical analysis identified significant differences in salinity (EC), the road salt related chemistry (Na & Cl), and secondary soil related salt chemistry (Ca, Mg & SO (sub 4) ) between UP and the greater concentrations in the DOWN surface water. Ground water at the UP and DOWN sites also differed; the DOWN wells all had significantly greater salt concentrations than the corresponding depths in the UP wells The DOWN ground water salts were significantly greater in the right bank (RB) than the left bank (LB) for Na, Cl, Ca and SO (sub 4) concentrations but Mg concentrations were greater in the LB. During wetter periods (e.g. during road salt application) associated research on the pre-restoration water levels had a toward the stream gradient, but during drought, the RB reversed gradient. The RB cation chemical composition was dominated by Na and was more variable than the Ca dominated LB. Groundwater quality differed after the restoration. Restoration restructured the DOWN-LB, Na significantly decreased in the wells after restoration but there were significant increasing Na trends. Significant increasing trends also occurred for Cl in these LB wells. Whether the current increasing trends will return to and stabilize at the pre-restoration concentrations is unknown. If the increasing trend in the surface water salinity is indicative, then well water trends are also expected to persist. Salt concentrations are not at levels likely to be detrimental to the stabilizing vegetation. Storm event precipitation induced EC spikes indicated pulsed, elevated salt levels that may affect aquatic biota.

These data were combined to characterize a contamination plume that impacts groundwater underlying a residential area. The residential area is located in a stream valley filled with complex unconsolidated glacial, glaciofluvial, and fluvial deposits up to 100 feet thick which are underlain by bedrock. During the Remedial Investigation (RI) at a U.S. Environmental Protection Agency (EPA) Superfund site in New York, groundwater quality data were collected by EPA and other agencies at the site over a period of five years. The data, collected under separate phases of work, were combined to characterize changes in groundwater contamination. The RI data collected in 2007 were combined with data collected from 2003 through 2008 by other agencies to characterize long-term plume behavior. To determine the trends in the concentrations at different locations within the plume, the data were graphed and mapped. Data from a group of wells perpendicular to the direction of groundwater flow were evaluated to characterize plume migration. Trichloroethene (TCE) and 1,1,1-trichloroethane (1,1,1-TCA) were used to define the plume. In the summer of 2007, the plumes of TCE and 1,1,1-TCA contaminated groundwater in the unconsolidated valley deposits were, respectively, about 8,200 and 8,700 feet long. The plume geometry is primarily controlled by small, discontinuous preferential flow paths in the unconsolidated deposits, which are not easily located and sampled using conventional monitoring wells. To assess future risk to groundwater users, long-term trends in concentrations were analyzed using residential well sample data. The characterization of long-term contaminant changes showed that: 1) concentrations of TCE and 1,1,1-TCE in the core of the plume have steadily dropped over time from 250 micrograms per liter (mu g/L) to 90 mu g/L; 2) the highest concentrations are dispersing or diffusing and are not being detected downgradient; and 3) concentrations of TCE are beginning to be detected above the maximum contaminant level at some locations at the distal end of the plume, indicating the movement of TCE in groundwater.

AN - 734165497; 19953395 AB - Dioxins and dioxin-like compounds are primary examples of persistent organic pollutants that induce toxicity in both wildlife and humans. Over the past 200 years these compounds have been almost exclusively generated by human activity and have left a string of disasters in the wake of their accidental release. Most recently, the contamination of the Irish pork supply with dioxins resulted in an international recall of all Irish pork products. Epidemiologic data on human and ecological dioxin exposures have revealed a common pattern of biological response among vertebrate species, which is mediated through activation of the Aryl hydrocarbon Receptor (AhR). These AhR-mediated effects include profound consequences on the vertebrate individual exposed in early life with respect to myriad developmental endpoints including neurologic, immunologic, and reproductive parameters. Humans appear to be susceptible to these effects in a manner similar to that of the laboratory and wildlife species, which have demonstrated such outcomes. Furthermore, epidemiologic data suggest that there is little or no margin of exposure for humans with respect to these developmental effects. Given these concerns, prudent public health policy should include the continued reduction of exposures. JF - Journal of environmental science and health.

AN - 734062933; 19545189 AB - Hazardous site management in the United States includes remediation of contaminated environmental media and restoration of injured natural resources. Site remediation decisions are informed by ecological risk assessment (ERA), whereas restoration and compensation decisions are informed by the natural resource damage assessment (NRDA) process. Despite similarities in many of their data needs and the advantages of more closely linking their analyses, ERA and NRDA have been conducted largely independently of one another. This is the 4th in a series of papers reporting the results of a recent workshop that explored how ERA and NRDA data needs and assessment processes could be more closely linked. Our objective is to evaluate the technical underpinnings of recentmethods used to translate natural resource injuries into ecological service losses and to propose ways to enhance the usefulness of data obtained in ERAs to the NRDA process. Three aspects are addressed: 1) improving the linkage among ERA assessment endpoints and ecological services evaluated in the NRDA process, 2) enhancing ERA data collection and interpretation approaches to improve translation of ERA measurements in damage assessments, and 3) highlighting methods that can be used to aggregate service losses across contaminants and across natural resources. We propose that ERA and NRDA both would benefit by focusing ecological assessment endpoints on the ecosystem services that correspond most directly to restoration and damage compensation decisions, and we encourage development of generic ecosystem service assessment endpoints for application in hazardous site investigations. To facilitate their use in NRDA, ERA measurements should focus on natural resource species that affect the flow of ecosystem services most directly, should encompass levels of biological organization above organisms, and should be made with the use of experimental designs that support description of responses to contaminants as continuous (as opposed to discrete) variables. Application of a data quality objective process, involving input from ERA and NRDA practitioners and site decision makers alike, can facilitate identification of data collection and analysis approaches that will benefit both assessment processes. Because of their demonstrated relationships to a number of important ecosystem services, we recommend that measures of biodiversity be targeted as key measurement endpoints in ERA to support the translation between risk and service losses. Building from case studies of recent successes, suggestions are offered for aggregating service losses at sites involving combinations of chemicals and multiple natural resource groups. Recognizing that ERA and NRDA are conducted for different purposes, we conclude that their values to environmental decision making can be enhanced by more closely linking their data collection and analysis activities.

AN - 734057414; 19775192 AB - Mandated efforts to assess chemicals for their potential to bioaccumulate within the environment are increasingly moving into the realm of data inadequacy. Consequently, there is an increasing reliance on predictive tools to complete regulatory requirements in a timely and cost-effective manner. The kinetic processes of absorption, distribution, metabolism, and elimination (ADME) determine the extent to which chemicals accumulate in fish and other biota. Current mathematical models of bioaccumulation implicitly or explicitly consider these ADME processes, but there is a lack of data needed to specify critical model input parameters. This is particularly true for compounds that are metabolized, exhibit restricted diffusion across biological membranes, or do not partition simply to tissue lipid. Here we discuss the potential of in vitro test systems to provide needed data for bioaccumulation modeling efforts. Recent studies demonstrate the utility of these systems and provide a "proof of concept" for the prediction models. Computational methods that predict ADME processes from an evaluation of chemical structure are also described. Most regulatory agencies perform bioaccumulation assessments using a weight-of-evidence approach. A strategy is presented for incorporating predictive methods into this approach. To implement this strategy it is important to understand the "domain of applicability" of both in vitro and structure-based approaches, and the context in which they are applied.

AN - 734057385; 19552498 AB - Environmental persistence is an important property that can enhance the potential of a chemical substance to exert adverse effects and be transported to remote environments. The persistence of organic compounds is governed by the rates at which they are removed by biological and chemical processes, such as biodegradation, hydrolysis, atmospheric oxidation, and photolysis. The persistence workgroup in a recent Society of Environmental Toxicology and Chemistry (SETAC) Pellston workshop (Pensacola, FL, USA, January 2008) focused on evaluating persistence of organic compounds in environmental media (air, water, soil, sediment) in terms of their single-medium degradation half-lives. The primary aim was to provide guidance to authors and reviewers of chemical dossiers for persistent organic pollutants (POPs) and persistent, bioaccumulative, and toxic substances (PBTs) proposed for action. A second objective was to provide a summary of the current state of the science with respect to POP fate assessment. Assessing the persistence of chemical substances in the environment is not straightforward. A common misconception is that, like many chemical properties, environmental persistence is an inherent property of the substance and can be readily measured. In fact, rates of degradation of a substance in the environment are determined by a combination of substance-specific properties and environmental conditions. This article addresses how persistence can be evaluated based on an assortment of supporting information. Special attention is given to several critical issues, including transformation products, nonextractable residues, and treatment of uncertainty and conflicting data as part of a weight-of-evidence assessment.

AN - 734047268; 19602574 AB - High visibility efforts in toxicity testing and computational toxicology including the recent National Research Council of the National Academies (NRC) report, Toxicity Testing in the 21st Century: A Vision and Strategy (NRC, 2007a), raise important research questions and opportunities for the field of exposure science. The authors of the National Academies report (NRC, 2007a) emphasize that population-based data and human exposure information are required at each step of their vision for toxicity testing and that these data will continue to play a critical role in both guiding development and use of the toxicity information. In fact, state-of-the-art exposure science is essential for translation of toxicity data to assess potential for risk to individuals and populations and to inform public health decisions. As we move forward to implement the NRC vision, a transformational change in exposure science is required. Application of a fresh perspective and novel techniques to capture critical determinants at biologically motivated resolution for translation from controlled in vitro systems to the open multifactorial system of real-world human-environment interaction will be critical. Development of an exposure ontology and knowledge base will facilitate extension of network analysis to the individual and population for translating toxicity information and assessing health risk. Such a sea change in exposure science is required to incorporate consideration of lifestage, genetic susceptibility, and interaction of nonchemical stressors for holistic assessment of risk factors associated with complex environmental disease. A new generation of scientific tools has emerged to rapidly measure signals from cells, tissues, and organisms following exposure to chemicals. Investment in 21st century exposure science is now required to fully realize the potential of the NRC vision for toxicity testing.

AN - 734046189; 19567883 AB - High costs, long test times, and societal concerns related to animal use have required the development of in vitro assays for the rapid and cost-effective toxicological evaluation and characterization of compounds in both the pharmaceutical and environmental arenas. Although the pharmaceutical industry has developed very effective, high-throughput in vitro assays for determining the therapeutic potential of compounds, the application of this approach to toxicological screening has been limited. A primary reason for this is that while drug candidate screens are directed to a specific target/mechanism, xenobiotics can cause toxicity through any of a myriad of undefined interactions with cellular components and processes. Given that it is not practical to design assays that can interrogate each potential toxicological target, an integrative approach is required if there is to be a rapid and low-cost toxicological evaluation of chemicals. Cellular stress response pathways offer a viable solution to the creation of a set of integrative assays as there is a limited and hence manageable set (a small ensemble of 10 or less) of major cellular stress response pathways through which cells mount a homoeostatic response to toxicants and which also participate in cell fate/death decisions. Further, over the past decades, these pathways have been well characterized at a molecular level thereby enabling the development of high-throughput cell-based assays using the components of the pathways. Utilization of the set of cellular stress response pathway-based assays as indicators of toxic interactions of chemicals with basic cellular machinery will potentially permit the clustering of chemicals based on biological response profiles of common mode of action (MOA) and also the inference of the specific MOA of a toxicant. This article reviews the biochemical characteristics of the stress response pathways, their common architecture that enables rapid activation during stress, their participation in cell fate decisions, the essential nature of these pathways to the organism, and the biochemical basis of their cross-talk that permits an assay ensemble screening approach. Subsequent sections describe how the stress pathway ensemble assay approach could be applied to screening potentially toxic compounds and discuss how this approach may be used to derive toxicant MOA from the biological activity profiles that the ensemble strategy provides. The article concludes with a review of the application of the stress assay concept to noninvasive in vivo assessments of chemical toxicants.

A dramatic increase in RAC reactivity with Pd doping at as low as 0.01% suggests its critical role for accelerating hydrodechlorination of PCBs. Characteristic adsorption and dechlorination behavior and ensuing decomposition pathways of 13 selected PCB congeners are discussed with their surface interactions with RAC. Important findings include (i) inherent dechlorination susceptibility of chlorines in para > meta > ortho position, regardless of independent or competitive conditions as well as substrate effects, (ii) favorable reduction of more toxic coplanar PCB congeners, (iii) preferential electrophilic attack to chlorines in a less substituted phenyl ring and an isolated chlorine, regardless of the steric or inductive effect as a dominant limiting factor for the dechlorination of ortho or meta PCBs, respectively, (iv) prominent dechlorination inhibition for higher ortho congeners but negligible inhibition for higher meta congeners, and (v) eventual complete dechlorination of higher PCB congeners to biphenyl.

AN - 67650680; 19694782 AB - Anthropogenic nitrogen (N) enrichment of ecosystems, mainly from fuel combustion and fertilizer application, alters biogeochemical cycling of ecosystems in a way that leads to altered flux of biogenic greenhouse gases (GHGs). Our meta-analysis of 313 observations across 109 studies evaluated the effect of N addition on the flux of three major GHGs: CO(2), CH(4) and N(2)O. The objective was to quantitatively synthesize data from agricultural and non-agricultural terrestrial ecosystems across the globe and examine whether factors, such as ecosystem type, N addition level and chemical form of N addition influence the direction and magnitude of GHG fluxes. Results indicate that N addition increased ecosystem carbon content of forests by 6%, marginally increased soil organic carbon of agricultural systems by 2%, but had no significant effect on net ecosystem CO(2) exchange for non-forest natural ecosystems. Across all ecosystems, N addition increased CH(4) emission by 97%, reduced CH(4) uptake by 38% and increased N(2)O emission by 216%. The net effect of N on the global GHG budget is calculated and this topic is reviewed. Most often N addition is considered to increase forest C sequestration without consideration of N stimulation of GHG production in other ecosystems. However, our study indicated that although N addition increased the global terrestrial C sink, the CO(2) reduction could be largely offset (53-76%) by N stimulation of global CH(4) and N(2)O emission from multiple ecosystems.

In natural environments, inorganic ligands can compete with organic ligands for surface sites on (oxyhydr)oxides which may influence dissolution rates. Published research of this interaction and its effect on the dissolution of (oxyhydr)oxides is rare. The objective of the present study was to examine the extent to which silica, as a naturally occurring competitive ligand added in the form of silicic acid, impacts the oxalate-promoted dissolution of the common soil Fe (oxyhydr)oxide goethite. Sorbed silica reduced the oxalate-promoted dissolution rate of goethite at all surface coverages investigated. As initial silica solution concentrations increased from 0.50 mM to 5.0 mM, relatively little change in the dissolution rate was observed. Fourier-transform infrared (FTIR) spectra indicated that, as silica-surface coverages increased, the silica underwent polymerization on the goethite surface. Initially, silicate was associated with surface functional groups, but as polymerization occurred some of the silica appeared to desorb from the goethite surface without being released into the bulk solution, suggesting that silica polymers formed discrete islands or surface clusters that grew away from the goethite surface rather than expanding epitaxially across the surface. Minimal changes were observed in the quantity of reactive goethite surface, which is responsible for the observed dissolution rates, as silica-surface coverages increased.

These quantities were derived from data generated in the mid-1990s. Studies conducted in the 2000s were gathered in an attempt to update the estimates generated by the Reassessment. While these studies suggest declines in the average background dose and body burden, a precise quantification of this decline, much less a conclusion that a decline has indeed occurred, cannot be made because of the inconsistency of study design and data sources, and the treatment of non-detects in the generation of congener average concentrations. The average background intake of the Reassessment was 61.0pgTEQ/day, and using more current data, the average background intake was 40.6pgTEQ/day. The average body burden from the surveys in the mid-1990s was 22.9pgTEQ/g lipid weight (pg /glwt). More recent blood concentration data, from NHANES 2001/2, suggest an adult average at 21.7pg/g TEQ lwt. These TEQ values include the 17 dioxin and furan congeners and 3 coplanar PCBs, and were generated substituting ND=1/2DL or ND=DL/sq rt (2). Results are provided for ND=0 and analyses conducted to evaluate the impacts of this substitution. A more detailed examination of beef and pork data from similarly designed national statistical surveys show that declines in pork are statistically significant while the beef concentrations appeared to have remained constant between the time periods.

With industrial activity and population expected to increase for the rest of the century, large increases in greenhouse gas emissions are projected, with substantial global additional warming predicted. This paper examines forces driving CO(2) emissions, a concise sector-by-sector summary of mitigation options, and research and development (R&D) priorities. To constrain warming to below approximately 2.5 C in 2100, the recent annual 3% CO(2) emission growth rate needs to transform rapidly to an annual decrease rate of from 1 to 3% for decades. Furthermore, the current generation of energy generation and end-use technologies are capable of achieving less than half of the emission reduction needed for such a major mitigation program. New technologies will have to be developed and deployed at a rapid rate, especially for the key power generation and transportation sectors. Current energj technology research, development, demonstration, and deployment (RDD&D) programs fall far short of what is required.

Complex cell systems, such as the Biologically Multiplexed Activity Profiling (BioMAP) primary, human, cell-based disease models, leverage cellular regulatory networks to detect and distinguish chemicals with a broad range of target mechanisms and biological processes relevant to human toxicity. Here the authors use the BioMAP human cell systems to characterize effects relevant to human tissue and inflammatory disease biology following exposure to the 320 environmental chemicals in the Environmental Protection Agency's (EPA's) ToxCast phase I library. The ToxCast chemicals were assayed at 4 concentrations in 8 BioMAP cell systems, with a total of 87 assay endpoints resulting in more than 100,000 data points. Within the context of the BioMAP database, ToxCast compounds could be classified based on their ability to cause overt cytotoxicity in primary human cell types or according to toxicity mechanism class derived from comparisons to activity profiles of BioMAP reference compounds. ToxCast chemicals with similarity to inducers of mitochondrial dysfunction, cAMP elevators, inhibitors of tubulin function, inducers of endoplasmic reticulum stress, or NF Kappa B pathway inhibitors were identified based on this BioMAP analysis. This data set is being combined with additional ToxCast data sets for development of predictive toxicity models at the EPA.

We describe zinc uptake and release by respiratory epithelial cells and test the postulate that Zn super(2+) transport interacts with iron homeostasis in these same cells. Zn super(2+) uptake after 4 and 8h of exposure to zinc sulfate was concentration- and time-dependent. A majority of Zn super(2+) release occurred in the 4h immediately following cell exposure to ZnSO sub(4). Regarding metal importers, mRNA for Zip1 and Zip2 showed no change after respiratory epithelial cell exposure to zinc while mRNA for divalent metal transporter (DMT)1 increased. Western blot assay for DMT1 protein supported an elevated expression of this transport protein following zinc exposure. RT-PCR confirmed mRNA for the metal exporters ZnT1 and ZnT4 with the former increasing after ZnSO sub(4). Cell concentrations of ferritin increased with zinc exposure while oxidative stress, measured as lipid peroxides, was decreased supporting an anti-oxidant function for Zn super(2+). Increased DMT1 expression, following pre-incubations of respiratory epithelial cells with TNF-a, IFN-g, and endotoxin, was associated with significantly decreased intracellular zinc transport. Finally, incubations of respiratory epithelial cells with both zinc sulfate and ferric ammonium citrate resulted in elevated intracellular concentrations of both metals. We conclude that exposure to zinc increases iron uptake by respiratory epithelial cells. Elevations in cell iron can possibly affect an increased expression of DMT1 and ferritin which function to diminish oxidative stress. Comparable to other metal exposures, changes in iron homeostasis may contribute to the biological effects of zinc in specific cells and tissues.

Anthropogenic influences, such as seasonal water diversion for municipal supplies, can increase this variability further. This study evaluates the seasonal and spatial variation of metal loads from estimated natural flows in a typical Rocky Mountain watershed impacted by historic hardrock mining and municipal water diversions: the Upper Tenmile Creek Watershed near Helena, Montana. Restoration of natural flows is being considered as part of broader watershed restoration measures, and an understanding of the variation in loads resulting from these flows is needed for restoration planning and design. Estimates of tributary and metal point and nonpoint source natural flows to the creek were used with representative total metals (cadmium, copper, lead, and zinc) concentration data for model input and to evaluate the variation of input loads. These loads were evaluated at key locations in the watershed for two seasons: spring snowmelt high flow in June and summer low flow in August. The Water Quality Analysis Simulation Program was used to model the resulting variation of total and dissolved metal loads with distance along the mainstem for the two seasons. Results show that total metal loads to the creek vary among input locations by up to >9,700-fold in June and up to >740-fold in August for copper. Several tributaries have the greatest loads during both seasons, although adits often exhibit the highest concentrations. For all locations, average input loads are up to 46 times higher in June for copper. Total and dissolved metal loads generally increase with distance along the mainstem and vary by up to >320-fold in August and up to >118-fold in June for zinc. Along the mainstem, average total loads are up to 68 times higher in June for lead. Many watershed and biogeochemical processes contribute to this variation, including variability in estimated natural flows, partitioning of metals between the dissolved and particulate phases, and attenuation in the hyporheic zone. Dissolved phases constitute a large proportion of the total metals and follow patterns very similar to those for total loads along the mainstem, especially for cadmium and zinc. Seasonal load differences are greatest for copper and lead because of greater sorption to solids and particulate loads during high flow associated with increased erosion and transport of solids.

Natural attenuation (i.e., sequestration) of As may, under appropriate geochemical conditions, serve to limit human exposure to As. The effectiveness of As sequestration by sorption, co-precipitation, and/or precipitation can be strongly influenced by redox conditions, which can control the solubility of sorbent phases and the stability of As-containing solids. The redox transformation of As between the +III and +V oxidation states can also affect the extent of As sorption. The effect of amendment with synthetic manganese (Mn) oxide birnessite (nominally MnO sub(2)) on As sequestration in a sediment suspension was examined in the absence and presence of iron (Fe) added as Fe(II). In the absence of Fe(II), the extent of As(III) oxidation to As(V) increased with increasing birnessite amendment, but As sequestration was not increased. In the presence of Fe(II), however, As sequestration did increase with increasing birnessite amendment. Concurrently, Fe(II) was also sequestered, and the Fe(III) content of the solid phase was observed to increase, suggesting that the oxidative precipitation of an Fe(III) oxyhydroxide phase plays an important role in As sequestration. These results suggest that amendment with Mn(III, IV) oxides could be an effective way to augment natural attenuation of As in cases where As-contaminated groundwater also contains elevated concentrations of Fe(II).

Concentrations of eight PFAs were determined in three species of fish (mullet, shad, and rockfish) and three species of marine invertebrates (blue crab, oyster, and mussel) from Lake Shihwa, Korea. This is an area in which relatively great concentrations of PFAs in water and in adjacent industrial effluents have been reported. PFOS was the dominant PFA in marine organisms and most PFOS concentrations were greater than the sum of all other PFAs. The mean concentrations of PFOS were 8.110 and 3.610ng/g, wet weight in liver and blood of fish, respectively. Perfluorocarboxylic acids (PFCAs) were also found in fish, but their concentrations were 10-fold less than those for PFOS. Of the PFCAs measured in fish, concentrations of the longer-chain perfluoroundecanoic acid (PFUnA) were the greatest. Concentrations of PFOS in soft tissues of blue crabs decreased as a function of distance from the shore where inputs from the industrialized areas are discharged into Lake Shihwa. PFOS was the only PFA detectable in mussels and oysters with a mean of 0.5c0.2 and 1.1c0.3ng/g, wet weight, respectively. Concentrations of PFUnA were positively correlated with perfluorodecanoic acid (PFDA) in both the liver and blood of fish, which suggests a common source of these two PFCAs in this area. Hazard quotients developed for fish species were all less than 1.0 for fish collected in Lake Shihwa.

The stream is devoid of fish primarily because of high metal concentrations in the water (e.g., copper and zinc) and has large amounts of settled iron oxyhydroxide solids that coat the streambed. The NFCC is part of the Central City/Clear Creek Superfund site, and remediation plans are being implemented that include treatment of three of the main point-source inputs and cleanup of some tailings and waste rock piles. This article examines dissolved (0.45-m filterable) concentrations of cadmium, copper, and zinc following several potential remediation scenarios, simulated using a reactive transport model (WASP4/META4). Results from modeling indicate that for cadmium, remediation of the primary point-source adit discharges should be sufficient to achieve acute and chronic water-quality standards under both high- and low-flow conditions. To achieve standards for copper and zinc, however, the modeling scenarios suggest that it may be necessary to treat or remove contaminated streambed sediments in downstream reaches, as well as identify and treat nonpoint sources of metals. Recommendations for improvements to the model for metal transport in acid-mine drainage impacted streams are made. These recommendations are being implemented by the U.S. Environmental Protection Agency.

Convective-scale weather warnings are unique in the NWS, having little reliance on direct numerical forecast guidance. Because increasing severe thunderstorm, tornado, and flash-flood warning lead times are a key NOAA strategic mission goal designed to reduce the loss of life, injury, and economic costs of these high-impact weather phenomena, a new warning paradigm is needed in which numerical model forecasts play a larger role in convective-scale warnings. This new paradigm shifts the warning process from warn on detection to warn on forecast, and it has the potential to dramatically increase warning lead times. A warn-on-forecast system is envisioned as a probabilistic convective-scale ensemble analysis and forecast system that assimilates in-storm observations into a high-resolution convection-resolving model ensemble. The building blocks needed for such a system are presently available, and initial research results clearly illustrate the value of radar observations to the production of accurate analyses of convective weather systems and improved forecasts. Although a number of scientific and cultural challenges still need to be overcome, the potential benefits are significant. A probabilistic convective-scale warn-on-forecast system is a vision worth pursuing.

Reserve site selection models use numerical optimization techniques to select sites for a network of nature reserves for protecting biodiversity. In this paper, we develop a population viability analysis (PVA) model for salmon and incorporate it into an RSS framework for prioritizing conservation activities in upstream watersheds. We use spawner return data for three closely related salmon stocks in the upper Columbia River basin and estimates of the economic costs of watershed protection from NOAA to illustrate the framework. We compare the relative cost-effectiveness of five alternative watershed prioritization methods, based on various combinations of biological and economic information. Prioritization based on biological benefit-economic cost comparisons and accounting for spatial interdependencies among watersheds substantially outperforms other more heuristic methods. When using this best-performing prioritization method, spending 10% of the cost of protecting all upstream watersheds yields 79% of the biological benefits (increase in stock persistence) from protecting all watersheds, compared to between 20% and 64% for the alternative methods. We also find that prioritization based on either costs or benefits alone can lead to severe reductions in cost-effectiveness.

There are now over 170 Federal laws that regulate environmental activities which may affect wildlife. Two important laws are the Pittman-Robertson Act enacted in 1937 that authorizes a tax for wildlife management and the Fish and Wildlife Coordination Act passed in 1958 whose primary purpose is conservation of fish and wildlife, both of which continue to provide significant funding for wildlife management. Modern environmental regulations began by passage of the National Environmental Policy Act in 1969, followed by the Clean Water Act, Superfund, and other laws to regulate pesticides and toxics and clean up contaminated sites. International conventions regulate sale, use and disposal of toxics and ocean dumping. These laws and conventions should protect wildlife from unintended consequences of global industrialization.

Standardizing data for toxicological models may be necessary to reduce extraneous variation and to ensure models reflect intrinsic relationships. However, the extent to which data standardization is necessary remains unclear, particularly when data transformations are used in model development. An extensive acute toxicity database was compiled for aquatic species to comprehensively assess the variation associated with acute toxicity test type (e.g., flow-through, static), reporting concentrations as nominal or measured, and organism life stage. Three approaches were used to assess the influence of these factors on log-transformed acute toxicity: toxicity ratios, log-linear models of factor groups, and comparison of interspecies correlation estimation (ICE) models developed using either standardized test types or reported concentration type. In general, median ratios were generally less than 2.0, the slopes of log-linear models were approximately one for well-represented comparisons, and ICE models developed using data from standardized test types or reported concentrations did not differ substantially. These results indicate that standardizing test data by acute test type, reported concentration type, or life stage may not be critical for developing ecotoxicological models using large datasets of log-transformed values.

An emphasis is placed on the avoidance of land-use conflict issues and, hence, on the prioritization of waste/residue utilization before dedicated energy crops are grown. It is concluded that up to 5.3% of the 2010 demand for biofuels can be met from the utilization of feasible quantities of wastes and residues in near-term biorefining technologies and that 5% of the 2020 petrol and diesel demand can be met via processing a similar quantity of waste in advanced biorefining processes based on consolidated bioprocessing micro-organisms and syngas-reforming catalysts. The remaining biofuel requirements for 2020 can be met by processing energy crops. Between 1.4% and 15.9% of the agricultural area of Ireland is required for the production of these crops, depending on the particular feedstock and technology employed. The production of a high-yielding Miscanthus crop that is harvested directly after senescence will place the minimum requirement on Irish land.

S. certified non-catalytic wood stove and a zero-clearance fireplace burning Quercus rubra L. (northern red oak) and Pseudotsuga menziesii (Douglas fir) cordwood each at two different moisture levels were determined. Emission testing was performed using both time-integrated and continuous instrumentation for total particle mass, particle number, particle size distribution, and fixed combustion gases using an atmospheric wind tunnel, full-flow laboratory dilution tunnel, and dilution stack sampler with a comparison made between the three dilution systems and two sampling filter types. The total mass emission factors (EFs) for all dilution systems and filter media are extremely variable ranging from <1 to ~55 g kg super(-) super(1) of dry wood depending on the combination of appliance type, wood species and moisture content, filter medium, and dilution system. For Teflon filter sampling of stove emissions in the wind tunnel, the total mass EFs varied from arrow up to 8 g kg super(-) super(1) of dry fuel depending on wood type whereas the equivalent fireplace emissions burning wet oak averaged 11 g kg super(-) super(1). A substantial number of ultrafine particles in the accumulation size range were also observed during all tests as determined by an Electrical Low Pressure Impactor (ELPI) and Scanning Mobility Particle Sizer. The PM-2.5 (particles approximately equal to 2.5 mu m in aerodynamic diameter) fractions determined from the ELPI electrometer data ranged from 93 to 98% (mass) depending on appliance type as reported previously by Hays et al.

A wind tunnel experiment modeling 12 different configurations was performed to study the flow fields and the concentration distributions resulting from emissions from a simulated six-lane highway. All of the configurations examined here reduced the downwind ground-level concentrations relative to that for a flat, unobstructed roadway; however, the degree to which the concentrations were reduced varied widely depending on the particular situation. Ground-level concentration data from the cases considered in this research indicate that a constant entrainment velocity can be used over the region beginning downwind of any initial disturbance to the flow resulting from the roadway configuration (e.g., a recirculation region behind a noise barrier) and extending at least to the end of our measurements. For example, for the case of a single noise barrier on the downwind side of the road, this region extends from approximately four barrier heights downwind of the roadway to 40 barrier heights. It was also found that the virtual origin concept is useful in describing the initial mixing created by the particular roadway configuration. To effectively model the influence of the roadway configuration on the dispersion, a combination of a virtual origin and an entrainment velocity may be effective. The magnitude of the virtual origin shift appears to depend on the particular roadway configuration, while the entrainment velocity appears to be a function of the friction velocity and the roadway geometry.

Macroinvertebrate communities are highly variable and complex and respond to a diverse series of environmental conditions. The purpose of this study was to examine the relative importance of environmental variables in explaining macroinvertebrate abundance. A total of 45 sub-alpine lakes were sampled for macroinvertebrates in the shallow sublittoral. Environmental variables were grouped into four types: (1) aquatic physical and chemical parameters, (2) littoral and riparian habitat, (3) lake morphometric parameters and (4) sediment chemical characteristics. Nonparametric multiplicative regression (NPMR) was used to model the abundance of individual macroinvertebrate taxa. Significant models were produced for nine out of the 24 taxa examined. Sediment characteristics were the group most frequently included in models and also the factors to which taxa abundance was the most sensitive. Aquatic physical and chemical variables were the next group most frequently included in models although chlorophyll a was not included in any of the models and total phosphorus in only one. This indicates that many taxa may not show a direct easily interpretable response to eutrophication pressure. Lake morphometric factors were included in several of the models although the sensitivity of macroinvertebrate abundance tended to be lower than for sediment and aquatic physical and chemical factors. Habitat factors were only included in three models although riparian vegetation was found to have a significant influence on the abundance of Ephemera danica indicating that ecotone integrity is likely to play a role in its ecology. Overall, the models tended to be specific for species with limited commonality across taxa. Models produced by NPMR indicate that the response of macroinvertebrates to environmental variables can be successfully described but further research is required focussing in more detail on the response of key taxa to relevant environmental parameters and anthropogenic pressures.

Worldwide, policy responses to climate change are increasing the attractiveness of investment in regrowth protection or facilitation which with strategic planning could also deliver substantial dividends for biodiversity conservation. This study compares the performance of two commonly used indicators of biodiversity conservation priority, irreplaceability and complementarity, as tools to support planning for iterative investment to protect natural regrowth of Brigalow, an endangered ecological community in subtropical eastern Australia. Brigalow covered more than seven million hectares prior to clearing, it now persists 'intact' on less than a tenth of that area but there are significant areas of regrowth. Data on Brigalow regrowth derived from mapping and remote sensing identify 10,555 patches covering 280,000 hectares in total. Two different classifications are used to represent Brigalow biodiversity: a land-type classification of 16 'regional ecosystems' mapped at 1:100,000 scale, and a landscape-scale classification of 40 biogeographic subregions that discriminate relatively uniform landscapes at about 1:500,000 scale. Conservation targets are expressed as the extent of regrowth needed to increase the extent of intact or 'remnant' areas of each biodiversity feature to either 5% or 10% of its former extent. In each case, irreplaceability and complementarity are positively correlated, and either metric type could be used to identify relatively large sets of high-priority patches. However, regional-scale restoration is likely to involve iterative investment and therefore to require discrimination of relatively small sets of patches of the highest priority for biodiversity conservation. Irreplaceability is not an ideal measure of biodiversity value when planning such iterative processes, simply because irreplaceability is uninformative for ranking 'high-value' patches; they all have the highest possible score. This study demonstrates the importance of considering quite fundamental points when choosing metrics for conservation planning, such as the frequency distribution of values they produce. Where planning aims to identify quite small sets of very high value features metrics that are most variable among the highest value patches, like the one used for complementarity in this study, will be more useful than metrics that are strongly bounded at higher values.

The method presented here uses a clustering approach to look beyond the extant urban area at multiple scales. The result is a single, synoptic multi-scale map of urban influence that should be useful in urban, regional and environmental planning efforts.

Chlorhexidine diacetate (CHX) is a biguanide disinfectant used for bacterial control in the hospital and agricultural and domestic environments. A better understanding of the mechanism of action of CHX and the resulting response elicited by P. aeruginosa to CHX will facilitate its effective utilization for P. aeruginosa control in these environments. This study presents, for the first time, the transcriptomic response of P. aeruginosa to 0.008 mM CHX after 10 and 60 min. Our results reveal that, after both treatment times, membrane transport, oxidative phosphorylation, and electron transport genes were downregulated. After 10 min, DNA repair was downregulated and the oprH gene that blocks the self-promoted uptake of antimicrobials was upregulated. After 60 min, outer membrane protein, flagellum, pilus, oxidative phosphorylation, and electron transport genes were downregulated. The mexC and mexD genes of the MexCD-OprJ multidrug efflux pump were significantly upregulated after both treatment times. The results of this study improve our understanding of the mode of action of CHX on P. aeruginosa and provide insights into the mechanism of action of other biguanide disinfectants which can be used for the development of more efficient disinfectants.

We show, for the first time, how spatial models based on PAHs intercepted by lichens can be used for fingerprinting multisource atmospheric pollution in a regional area. Urban-industrial areas showed the highest atmospheric deposition of PAHs followed by urban > industrial > agricultural > forest. Multivariate analysis of lichen data showed, for the first time, a clear distinction between various sources of PAHs in the same area: urban are dominated by 4-ring PAHs, forest by 3-ring PAHs, and industrial by 5- and 6-ring PAHs or by 2-ring PAHs (petrogenic or pyrogenic, respectively). Heavy metals were also used for supporting the fingerprinting of PAH sources, reinforcing the industrial origin of 5- and 6-ring PAHs and revealing their particular nature. The spatial structure of the models for different PAHs seems to be dependent on the following factors: size and hydrophilic character of different PAHs, type of emission sources (point or nonpoint), and dispersion associated with particulates of different sizes.

Because of their unique properties, nanotubes can impose potentially toxic effects, particularly if they have been modified to express functionally reactive chemical groups on their surface. The present study was designed to evaluate whether acid functionalization (AF) enhanced the cardiopulmonary toxicity of single-walled carbon nanotubes (SWCNT) as well as control carbon black particles. Mice were exposed by oropharyngeal aspiration to 10 or 40 kg of saline-suspended single-walled carbon nanotubes (SWCNTs), acid-functionalized SWCNTs (AF-SWCNTs), ultrafine carbon black (UFCB), AF-UFCB, or 2 kg LPS. 24 hours later, pulmonary inflammatory responses and cardiac effects were assessed by bronchoalveolar lavage and isolated cardiac perfusion respectively, and compared to saline or LPS-instilled animals. Additional mice were assessed for histological changes in lung and heart. Instillation of 40 kg of AF-SWCNTs, UFCB and AF-UFCB increased percentage of pulmonary neutrophils. No significant effects were observed at the lower particle concentration. Sporadic clumps of particles from each treatment group were observed in the small airways and interstitial areas of the lungs according to particle dose. Patches of cellular infiltration and edema in both the small airways and in the interstitium were also observed in the high dose group. Isolated perfused hearts from mice exposed to 40 kg of AF-SWCNTs had significantly lower cardiac functional recovery, greater infarct size, and higher coronary flow rate than other particle-exposed animals and controls, and also exhibited signs of focal cardiac myofiber degeneration. No particles were detected in heart tissue under light microscopy. This study indicates that while acid functionalization increases the pulmonary toxicity of both UFCB and SWCNTs, this treatment caused cardiac effects only with the AF-carbon nanotubes. Further experiments are needed to understand the physico-chemical processes involved in this phenomenon.

Little is known, however, about their potential to adversely impact fish and other aquatic life. In this study we examined the kinetics and effects of dichloroacetic acid (DCA) in rainbow trout. Branchial uptake was measured in fish confined to respirometer-metabolism chambers. Branchial uptake efficiency was sub()) and t sub(1) sub(/) sub(2). Qualitatively similar results were obtained in low dose fish, although the magnitude of the pre-treatment effect (62.5-fold) was reduced. Renal and branchial clearance contributed little (combined, <3% of CL sub(B)) to the elimination of DCA. Biliary elimination of DCA was also negligible. The steady-state volume of distribution (V sub(S) sub(S)) did not vary among treatment groups and was consistent with results of the tissue distribution study. DCA had no apparent effects on respiratory physiology or acid-base balance; however, the concentration of blood lactate declined progressively during continuous waterborne exposures. A transient effect on blood lactate was also observed in bolus injection experiments. The results of this study suggest that clearance of DCA is due almost entirely to metabolism. The pathway responsible for this activity exhibits characteristics in common with those of mammalian glutathione S-transferase zeta (GSTz), including non-linear kinetics and apparent suicide inactivation by DCA. Observed effects on blood lactate are probably due to the inhibition of pyruvate dehydrogenase kinase in aerobic tissues and may require the participation of a monocarboxylase transport protein to move DCA across cell membranes.

Experiments were conducted using a smog chamber operated in a steady-state mode permitting measurements of moderately low aerosol levels. GC-MS analysis was conducted to measure methyl butenediols in the gas phase and polyols in the aerosol phase. Analyses were made to obtain several bulk aerosol parameters from the reaction including values for the organic mass to organic carbon ratio, the effective enthalpy of vaporization ( Delta H sub(vap) super(eff)), organic peroxide fraction, and the aerosol yield. The gas phase analysis showed the presence of methacrolein, methyl vinyl ketone, and four isomers of the methyl butenediols. These gas-phase compounds may serve as precursors for one or more of several compounds detected in the aerosol phase including 2-methylglyceric acid, three 2-methyl alkenetriols, and two 2-methyl tetrols. In contrast to most previous studies, the 2-methyl tetrols (and the 2-methyl alkenetriols) were found to form in the absence of acidic sulfate aerosol. However, reaction conditions did not favor the production of HO sub(2) radicals, thus allowing RO sub(2)+RO sub(2) reactions to proceed more readily than if higher HO sub(2) levels had been generated. SOA/SOC (i.e. OM/OC) was found to average 1.9 in the absence of NO sub(x). The effective enthalpy of vaporization was measured as 38.6 kJ mol super(− 1), consistent with values used previously in modeling studies. The yields in this work (using an independent technique than used previously) are lower than those of Kroll et al. (2006) for similar aerosol masses. SOC yields reported in this work range from 0.5-1.4% for carbon masses between 17 and 49 mu gC m super(− 3).

Although there is a need to understand the chronic and sublethal impacts of contaminants, it is common to conduct only short-term lethality tests in evaluations of marine sediments. Chronic toxicity methods for marine sediments have been developed but the efficacy of these methods is less documented. In this evaluation of marine sediments collected from the New York/New Jersey (NY/NJ) Harbor, three 10-d acute toxicity test methods (Ampelisca abdita, Leptocheirus plumulosus, Americamysis bahia) and three chronic and sublethal test methods (28-d L. plumulosus, 20- and 28-d Neanthes arenaceodentata) were applied by three testing laboratories. Although the N. arenaceodentata and A. bahia tests did not indicate significant toxicity for the sediments tested in this study, these methods have been reported useful in evaluating other sediments. The 10-d A. abdita, 10-d L. plumulosus and 28-d L. plumulosus tests were comparable between laboratories, indicating 29-43%, 29%, and 43-71% of the tested sediments as potentially toxic. The 28-d L. plumulosus method was the only chronic toxicity test that responded to the test sediments in this study. The 28-d L. plumulosus endpoint magnitudes were related to sediment chemistry and the sublethal endpoints were reduced as much or more than acute lethality endpoints. However, intra-treatment sublethal endpoint variability was greater, compromising detection of statistical significance. In this study, the chronic L. plumulosus test method was less consistent among laboratories relative to acute test methods, identifying potential for toxicity in a similar number (or slightly more) NY/NJ Harbor sediments.

Increased atmospheric carbon dioxide concentration acts as a fertilizer for plant growth. The fertilizing effects of carbon dioxide, as well as increased temperatures from climate change, increase pollen production and the allergen content of pollen grains. In addition, higher temperatures are changing the timing and duration of the pollen season. As regional climates change, plants can move into new areas and changes in atmospheric circulation can blow pollen- and spore-containing dust to new areas, thus introducing people to allergens to which they have not been exposed previously. Climate change also influences the concentrations of airborne pollutants, which alone, and in conjunction with aeroallergens, can exacerbate asthma or other respiratory illnesses. The few epidemiological analyses of meteorological factors, aeroallergens, and allergic diseases demonstrate the pathways through which climate can exert its influence on aeroallergens and allergic diseases. In addition to the need for more research, there is the imperative to take preventive and adaptive actions to address the onset and exacerbation of allergic diseases associated with climate variability and change.

AN - 734193057; 20002907 AB - This update (Version 2) of the Terminology of Developmental Abnormalities in Common Laboratory Mammals (Version 1) incorporates improvements and enhancements to both content and organization of the terminology to enable greater flexibility in its application, while maintaining a consistent approach to the description of findings. The revisions are the result of an international collaboration among interested organizations, advised by individual experts and the outcomes of several workshops. The terminology remains organized into tables under the broad categories of external, visceral, and skeletal observations, following the manner in which data are typically collected and recorded in developmental toxicity studies. This arrangement of the tables, as well as other information provided in appendices, is intended to facilitate the process of specimen evaluation at the laboratory bench level. Only the commonly used laboratory mammals (i.e. rats, mice, rabbits) are addressed in the current terminology tables. The inclusion of other species that are used in developmental toxicity testing, such as primates, is considered outside the scope of the present update. Similarly, categorization of findings as, for example, 'malformation' or 'variation' remains unaddressed, in accordance with the overall principle that the focus of this document is descriptive terminology and not diagnosis or interpretation. The skeletal terms have been augmented to accommodate cartilage findings.

AN - 734151021; 19374475 AB - High (maximum of 4.1 ppm lipid weight) levels of BDE-209 and other higher brominated diphenyl ethers (BDEs) found in California, USA, peregrine falcon (Falco peregrinus) eggs (n = 95) provided an opportunity to examine homolog profiles of nona-, octa-, and hepta-BDEs as possible evidence for biological debromination of BDE-209. We found two congeners in eggs, an unidentified hepta-BDE (BDE-heptaUNK) and BDE-202 (octa-BDE) that are not present in commercial mixtures. In addition, BDE-208 (nona-BDE) was present at much higher (10-fold) proportions in eggs than in commercial mixtures. To examine whether these unusual homolog patterns arose from assimilation of environmentally degraded BDE commercial mixtures, we compared nona-hepta-BDE homolog profiles of peregrine falcon eggs with those of weathered BDEs present in various abiotic matrices (sludge, sediment, and dusts). We found the profiles differed significantly: BDE-207 was the major nona-BDE in eggs, whereas BDE-206 was the major nona-BDE in abiotic matrices. Thus, the evidence for the biological debromination of BDE-209 in peregrine falcons is twofold: Eggs have two congeners (BDE-202 and -heptaUNK) that are not reported for any commercial mixtures nor in the abiotic matrices examined thus far, and eggs have higher-brominated BDE homolog patterns that are different from those found in commercial mixtures or environmental matrices.

AN - 734149964; 19413364 AB - Even though herbicide drift can affect plant reproduction, current plant testing protocols emphasize effects on vegetative growth. In this study, we determined whether a short-growing season plant can indicate potential effects of herbicides on seed production. Pea (Pisum sativum cv. Dakota) plants were grown in mineral soil in pots under greenhouse conditions. Plants were treated with a variety of herbicides (dicamba, clopyralid, glufosinate, glyphosate, 2-methyl-4-chlorophenoxyacetic acid, primisulfuron, or sulfometuron) at below standard field application rates applied at a vegetative stage of growth (approximately 14 d after emergence) or at flowering (approximately 20 d after emergence). Pea seed production was greatly reduced by sulfometuron at the minimum concentration used (0.001 x field application rate), with an effective concentration producing a 25% reduction in seed dry weight of 0.00007 x field application rate. Primisulfuron and glyphosate had a 25% reduction in seed dry weight for seed dry weight of 0.0035 and 0.0096 x field application rate, respectively. Clopyralid and dicamba reduced pea seed dry weight at a 25% reduction in seed dry weight of approximately 0.07 x field application rate. Glufosinate only reduced pea seed weight in one experiment, with a 25% reduction in seed dry weight of 0.07 and 0.008 x field application rate at vegetative growth and flowering stages, respectively. Pea seed dry weight was not affected by 2-methyl-4-chlorophenoxyacetic acid. Plant developmental stage had no consistent effect on herbicide responses. Reduced seed production occurred with some herbicides (especially acetolactate synthase inhibitors), which caused little or no reduction in plant height or shoot biomass and little visible injury. Thus, pea may be a model species to indicate seed reproductive responses to herbicides, with seed production obtained by extending plant growth for usually only 7 d longer than the period usually used in the vegetative vigor test.

AN - 734052879; 19715353 AB - There is a paucity of relevant experimental information available for the evaluation of the potential health and environmental effects of many man made chemicals. Knowledge of the potential pathways for activity provides a rational basis for the extrapolations inherent in the preliminary evaluation of risk and the establishment of priorities for obtaining missing data for environmental chemicals. The differential step in many mechanisms of toxicity may be generalized as the interaction between a small molecule (a potential toxicant) and one or more macromolecular targets. An approach based on computation of the interaction between a potential molecular toxicant and a library of macromolecular targets of toxicity has been proposed for preliminary chemical screening. In the current study, the interaction between a series of environmentally relevant chemicals and models of the rat estrogen receptors (ER) was computed and the results compared to an experimental data set of their relative binding affinities. The experimental data set consists of 281 chemicals, selected from the U.S. EPA's Toxic Substances Control Act (TSCA) inventory, that were initially screened using the rat uterine cytosolic ER-competitive binding assay. Secondary analysis, using Lineweaver-Burk plots and slope replots, was applied to confirm that only 15 of these test chemicals were true competitive inhibitors of ER binding with experimental inhibition constants (K(i)) less than 100 microM. Two different rapid computational docking methods have been applied. Each provides a score that is a surrogate for the strength of the interaction between each ligand-receptor pair. Using the score that indicates the strongest interaction for each pair, without consideration of the geometry of binding between the toxicant and the target, all of the active molecules were discovered in the first 16% of the chemicals. When a filter is applied on the basis of the geometry of a simplified pharmacophore for binding to the ER, the results are improved, and all of the active molecules were discovered in the first 8% of the chemicals. In order to obtain no false negatives in the model that includes the pharmacophore filter, only 8 molecules are false positives. These results indicate that molecular docking algorithms that were designed to find the chemicals that act most strongly at a receptor (and therefore are potential pharmaceuticals) can efficiently separate weakly active chemicals from a library of primarily inactive chemicals. The advantage of using a pharmacophore filter suggests that the development of filters of this type for other receptors will prove valuable.

Kinetically stable fullerene aggregates were formed using this procedure that ranged in intensity-averaged hydrodynamic diameter (Dh) from 193 +/- 2 nm (95% C.L.) for aqu/C60 to 259 +/- 6 nm for aqu/PCBO. Measured zeta potentials (zeta) were < -50 mV, and the isoelectric points (p) were < 1.0 for all of the aqu/fullerenes. Time-resolved dynamic light scattering (TRDLS) was used to measure aqu/fullerene Dh change with time and as a function of background solution ionic strength. The critical coagulation concentration (CCC) values for the aqu/PCB-R fullerenes were significantly higher than that of aqu/C60, indicating that the phenyl alkyl ester moieties of the equ/PCB-R fullerenes were impeding the aggregation process.

AN - 734051453; 19764260 AB - Sediment toxicity identification and evaluation (TIE) methods are relatively simple laboratory methods designed to identify specific toxicants or classes of toxicants in sediments; however, the question of whether the same toxicant identified in the laboratory is causing effects in the field remains unanswered. The objective of our study was to determine if laboratory TIE methods accurately reflect field effects. A TIE performed on sediments collected from the Elizabeth River (ER) in Virginia identified polycyclic aromatic hydrocarbons (PAHs) as the major toxicants. Several lines of evidence indicated PAHs were the major toxic agents in the field, including elevated PAH concentrations in ER sediments, comet assay results from in situ caged Merceneria merceneria, and chemical analyses of exposed M. merceneria, which indicated high PAH concentrations in the bivalve tissue. Our final evidence was the response from test organisms exposed to ER sediment extracts and then ultraviolet (UV) radiation. UV radiation caused a toxic diagnostic response unique to PAHs. The aggregation of these various lines of evidence supports the conclusion that PAHs were the likely cause of effects in laboratory- and field-exposed organisms, and that laboratory-based TIE findings reflect causes of field impairment JF - Environmental science & technology AU - Ho, Kay T AU - Gielazyn, Michel L AU - Pelletier, Marguerite C AU - Burgess, Robert M AU - Cantwell, Mark C AU - Perron, Monique M AU - Serbst, Jonathan R AU - Johnson, Roxanne L AD - Atlantic Ecology Division, U.S. Environmental Protection Agency, Narragansett, Rhode Island 02882, USA. ho.kay@epa.gov Y1 - 2009/09/01/ PY - 2009 DA - 2009 Sep 01 SP - 6857 EP - 6863 VL - 43 IS - 17 SN - 0013-936X, 0013-936X KW - Polycyclic Aromatic Hydrocarbons KW - 0 KW - Water Pollutants, Chemical KW - Index Medicus KW - Animals KW - Ultraviolet Rays KW - Virginia KW - Reproducibility of Results KW - Mercenaria -- metabolism KW - Laboratories KW - Mercenaria -- drug effects KW - Rivers -- chemistry KW - Polycyclic Aromatic Hydrocarbons -- toxicity KW - Polycyclic Aromatic Hydrocarbons -- pharmacokinetics KW - Water Pollutants, Chemical -- toxicity KW - Toxicity Tests -- methods KW - Environmental Monitoring -- standards KW - Water Pollutants, Chemical -- pharmacokinetics KW - Environmental Monitoring -- methods KW - Toxicity Tests -- standards UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/734051453?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Atoxline&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Environmental+science+%26+technology&rft.atitle=Do+toxicity+identification+and+evaluation+laboratory-based+methods+reflect+causes+of+field+impairment%3F&rft.au=Ho%2C+Kay+T%3BGielazyn%2C+Michel+L%3BPelletier%2C+Marguerite+C%3BBurgess%2C+Robert+M%3BCantwell%2C+Mark+C%3BPerron%2C+Monique+M%3BSerbst%2C+Jonathan+R%3BJohnson%2C+Roxanne+L&rft.aulast=Ho&rft.aufirst=Kay&rft.date=2009-09-01&rft.volume=43&rft.issue=17&rft.spage=6857&rft.isbn=&rft.btitle=&rft.title=Environmental+science+%26+technology&rft.issn=0013936X&rft_id=info:doi/ LA - English DB - ProQuest Environmental Science Collection N1 - Date completed - 2009-11-23 N1 - Date created - 2009-09-21 N1 - Date revised - 2017-01-13 N1 - Last updated - 2017-01-18 ER - TY - JOUR T1 - The inhibition of Pb(IV) oxide formation in chlorinated water by orthophosphate. AN - 734051353; 19764227 AB - Historically, understanding lead solubility and its control in drinking water has been based on Pb(II) chemistry. Unfortunately, there is very little information available regarding the nature of Pb(IV) oxides in finished drinking water and water distribution systems, and the conditions under which they persist. The objective of this research was to explore the impact of orthophosphate on the realistic pathways that lead to the formation of Pb(IV) oxides in chlorinated water. The results of XRD and XANES analysis showed that, in the absence of orthophosphate (DIC = 10 mg C/L, 24 degrees C, pH 7.75-8.1, 3 mg Cl2/L goal), Pb(IV) oxides formed with time following a transformation from the Pb(II) mineral hydrocerussite. Under the same experimental conditions, orthophosphate dosing inhibited the formation of Pb(IV) oxides. The Pb(II) mineral hydroxypyromorphite, Pb5(PO4)3OH, was the only mineral phase identified during the entire study of over 600 days, although the presence of some chloropyromorphite, Pb5(PO4)3Cl, could not be ruled out The conclusions were further supported by SEM, TEM, and XANES analysis of lead colloids, and lead precipitation experiments conducted in the absence of free chlorine. The findings provide an important explanation for the absence of Pb(IV) oxides in some water systems that have used, or currently use, orthophosphate for corrosion control when otherwise, based on disinfection practices and water quality, its presence would be anticipated, as well as why the conversion from free chlorine to chloramines was not observed to increase lead release.

AN - 733669444; 19764226 AB - Fluorotelomer polymers are used in a broad array of products in modern societies worldwide and, if they degrade at significant rates, potentially are a significant source of perfluorooctanoic acid (PFOA) and related compounds to the environment To evaluate this possibility, we incubated an acrylate-linked fluorotelomer polymer in soil microcosms and monitored the microcosms for possible fluorotelomer (FT) and perfluorinated-compound (PFC) degradation products using GC/MS and LC/MS/MS. This polymer scavenged FTs and PFCs aggressively necessitating development of a multistep extraction using two solvents. Aged microcosms accumulated more FTs and PFCs than were present in the fresh polymer indicating polymer degradation with a half-life of about 870-1400 years for our coarse-grained test polymer. Modeling indicates that more-finely grained polymers in soils might have half-lives of about 10-17 years assuming degradation is surface-mediated. In our polymer-soil microcosms, PFOA evidently was lost with a half-life as short as 130 days, possibly by polymer-catalyzed degradation. These results suggest that fluoratelomer-polymer degradation is a significant source of PFOA and other fluorinated compounds to the environment.

Where landholders are unfamiliar with conservation tender processes and the supply of environmental services, they may find it very difficult to construct bids in this way. Bid values may be influenced by other factors, such as concerns about 'winner's curse,' a desire to capture economic rent, and premiums for risk and uncertainty factors. Sealed, single round auctions may exacerbate information gaps and uncertainty factors because of the limited information flows compared to traditional market exchanges and open, ascending auctions. In this paper, the cost efficiencies of a multiple bidding round auction for landholder management actions are explored with the use of field experiments and a conservation auction. The case study application is improved grazing management in a rangeland area of Australia, where landholders are unfamiliar with supplying environmental services or conservation auctions. Results suggest that multiple round auctions may be associated with efficiency gains, particularly in initial rounds. // ABSTRACT IN FRENCH: Les enchères pour la conservation sont généralement des enchères au premier prix, à un tour, discriminatoires et par offre écrite. Elles reposent sur l'hypothèque que les offres des propriétaires fonciers refléteront leur «valeur privée». Lorsque les propriétaires fonciers ne sont pas familiers avec les processus d'enchères pour la conservation et la prestation de services environnementaux, ils peuvent éprouver de la difficulté à attribuer une valeur à leur offre. Cette valeur peut-être influencée par d'autres facteurs, tels que la crainte de la «malédiction du vainqueur», le désir de réaliser une rente économique, les primes de risque et les facteurs d'incertitude. Les enchères scellées à un tour peuvent aggraver le manque d'information et les facteurs d'incertitude étant donné que les enchérisseurs disposent de peu d'information comparativement aux enchères ascendantes ouvertes traditionnelles. Dans le présent article, nous avons examiné, à l'aide d'expériences sur le terrain et d'enchères pour la conservation, l'efficacité-coût d'une enchère à tours multiples pour des mesures de gestion de la part de propriétaires fonciers. L'exercice visait à améliorer la gestion des pâturages d'un parcours naturel en Australie, où les propriétaires fonciers ne sont pas familiers avec la prestation de services environnementaux ni avec les enchères pour la conservation. Les résultats autorisent à penser que les enchères à tours multiples pourraient offrir des gains d'efficience, particulièrement durant les premiers tours.

When final, the rule would compel most large sources of greenhouse gases (GHGs) to report their emissions to EPA as well as fossil fuel suppliers and vehicle engine manufacturers to report their fuel sales and engine emissions rates, respectively. We suggest a number of improvements to the rule that would enhance compatibility with expected future climate legislation and enable a broader range of policies and analysis: (1) lower the threshold for reporting to a level more consistent with expected future legislation, (2) require reporting of electricity use along with direct emissions, (3) require reporting of emissions per unit output for a small number of selected sectors, (4) include a system of identifying corporate ownership of reporting facilities, and (5) identify a path toward coverage for sectors that were left out of the proposal due to underdeveloped reporting protocols.

We examined the pattern and magnitude of urban-rural variation in anencephaly, spina bifida without anencephaly, and encephalocele in Texas in relation with urban-rural residence for the period 1999-2003. There was no evidence that urban-rural residence was associated with changes in the rate of anencephaly or spina bifida without anencephaly in unadjusted or adjusted analyses. In contrast, rates of encephalocele were statistically significantly higher in areas classified as suburban or more rural compared to urban areas using four different urban-rural residence indicators.

Rapid mapping of contaminant distributions is necessary to assess exposure risks and to plan remediation. Powdered aspirin or caffeine was dispersed across a concrete driveway using the exhaust port of a shop vacuum cleaner. Water-soaked, cotton-swab, wipe samples were collected to map the dispersant distribution. An autosampler/direct analysis in real time (DART [IonSense, Saugus, MA])/time-of-flight mass spectrometer was used to acquire an ion chromatogram for the most abundant ion. A semi-quantitation map for several levels of caffeine was plotted to demonstrate the feasibility of applying this technology to contaminated sites.

The analysis described in this article explores the use of the ecosystem model AQUATOX to investigate impairment thresholds keyed to biological indexes that can be simulated. The indexes selected for this exercise include percentage cyanobacterial biomass of sestonic algae, and benthic chlorophyll a. The calibrated model was used to analyze responses of these indexes to concurrent reductions in phosphorus, nitrogen, and suspended sediment in an enriched upper Midwestern river. Results suggest that the indexes would respond strongly to changes in phosphorus and suspended sediment, and less strongly to changes in nitrogen concentration. Using simulated concurrent reductions in all three water quality constituents, a total phosphorus concentration of 0.1mg/l was identified as a threshold concentration, and therefore a hypothetical water quality criterion, for prevention of both excessive periphyton growth and sestonic cyanobacterial blooms. This kind of analysis is suggested as a way to evaluate multiple contrasting impacts of hypothetical nutrient and sediment reductions and to define nutrient criteria or target concentrations that balance multiple management objectives concurrently.

Both methods were first verified with mixtures of heat-killed (nonviable) and non-heat-killed (viable) cells before a series of batch disinfection experiments with stationary-phase cultures (batch grown for 7 days) at pH 8.0, 25C, and 5, 10, and 20 mg Cl2/liter monochloramine. Two data sets were generated based on the viability method used, either (i) LD or (ii) PMA-qPCR. These two data sets were used to estimate kinetic parameters for the delayed Chick-Watson disinfection model through a Bayesian analysis implemented in WinBUGS. This analysis provided parameter estimates of 490 mg Cl2-min/liter for the lag coefficient (b) and 1.6 x 10-3 to 4.0 x 10-3 liter/mg Cl2-min for the Chick-Watson disinfection rate constant (k). While estimates of b were similar for both data sets, the LD data set resulted in a greater k estimate than that obtained with the PMA-qPCR data set, implying that the PMA-qPCR viability measure was more conservative than LD. For N. europaea, the lag phase was not previously reported for culture-independent methods and may have implications for nitrification in drinking water distribution systems. This is the first published application of a PMA-qPCR method for disinfection kinetic model parameter estimation as well as its application to N. europaea or monochloramine. Ultimately, this PMA-qPCR method will allow evaluation of monochloramine disinfection kinetics for mixed-culture bacteria in drinking water distribution systems.

However, there is little information on goose fecal microbial communities, and such data are important for the development of host-specific source-tracking methods. To address this issue, 16S rRNA gene clone libraries for Canada goose fecal samples from Ontario, Canada, and Ohio were analyzed. Analyses of fecal clones from Ontario (447) and Ohio (302) showed that goose fecal communities are dominated by the classes Clostridia (represented by 33.7% of clones) and Bacilli (38.1% of clones) and the phylum Bacteroidetes (10.1% of clones). Sequences not previously found in other avian fecal communities were used to develop host-specific assays. Fecal DNA extracts from sewage plants (10 samples) and different species of birds (11 samples) and mammals (18 samples) were used to test for host specificity. Of all the assays tested, one assay showed specificity for Canada goose fecal DNA. The PCR assay was positive for Canada goose fecal DNA extracts collected from three locations in North America (Ohio, Oregon, and Ontario, Canada). Additionally, of 48 DNA extracts from Lake Ontario waters presumed to be impacted by waterfowl feces, 19 tested positive by the assay, although 10 were positive only after a nested PCR approach was used. Due to the level of host specificity and the presence of signals in environmental waters, the assay is proposed as a part of the toolbox to detect Canada goose contamination in waterfowl-contaminated waters.

We report the development of quantitative PCR assays for quantification of two recently described human-specific genetic markers targeting Bacteroidales-like cell surface-associated genes. Each assay exhibited a range of quantification from 10 to 1 x 106 copies of target DNA. For each assay, internal amplification controls were developed to detect the presence or absence of amplification inhibitors. The assays predominantly detected human fecal specimens and exhibited specificity levels greater than 97% when tested against 265 fecal DNA extracts from 22 different animal species. The abundance of each human-specific genetic marker in primary effluent wastewater samples collected from 20 geographically distinct locations was measured and compared to quantities estimated by real-time PCR assays specific for rRNA gene sequences from total Bacteroidales and enterococcal fecal microorganisms. Assay performances combined with the prevalence of DNA targets in sewage samples provide experimental evidence supporting the potential application of these quantitative methods for monitoring fecal pollution in ambient environmental waters.

The assays were tested against 222 fecal DNA extracts derived from target and nontarget animal hosts and against 34 groundwater and 15 surface water samples from five different sites. We also investigated the phylogenetic diversity of 1,340 Bacteroidales 16S rRNA gene sequences derived from swine feces, swine waste lagoons, swine manure pits, and waters adjacent to swine operations. Most swine fecal samples were positive for the host-specific Prevotella-based PCR assays (80 to 87%), while fewer were positive with the methanogen-targeted PCR assay (53%). Similarly, the Prevotella markers were detected more frequently than the methanogen-targeted assay markers in waters historically impacted with swine fecal contamination. However, the PF163 PCR assay cross-reacted with 23% of nontarget fecal DNA extracts, although Bayesian statistics suggested that it yielded the highest probability of detecting pig fecal contamination in a given water sample. Phylogenetic analyses revealed previously unknown swine-associated clades comprised of clones from geographically diverse swine sources and from water samples adjacent to swine operations that are not targeted by the Prevotella assays. While deeper sequencing coverage might be necessary to better understand the molecular diversity of fecal Bacteroidales species, results of sequence analyses supported the presence of swine fecal pollution in the studied watersheds. Overall, due to nontarget cross amplification and poor geographic stability of currently available host-specific PCR assays, development of additional assays is necessary to accurately detect sources of swine fecal pollution.

Both the Agency for Toxic Substances and Disease Registry (ATSDR) and the United States Environmental Protection Agency (US EPA) recognize how public health may be improved by including a holistic approach to redevelopment that includes community health monitoring activities. Health monitoring goes beyond testing blood samples to address potentially toxic exposures and can be implemented to assess overall community health status throughout the course of community revitalization efforts. Examples of health monitoring activities include asthma or blood lead level screening, reviewing health statistics, environmental testing, and evaluation of community-specific health concerns. While health monitoring is encouraged as an activity within US EPA Brownfields funding, the number of communities that implement health monitoring programs is low. To encourage more communities to implement health monitoring activities, with or without Brownfields funding, this paper describes several projects by health agencies and communities to represent best practice examples. To facilitate more community health monitoring projects, the ATSDR has created and continues to create tools and resources to assist brownfield and land-reuse communities. In addition, the ATSDR and the US EPA are working together to build internal as well as community capacity to monitor community health through redevelopment activities.

This paper examines how each of these factors influences the magnitude of the $/ton estimate. We employ a reduced-form air quality model to predict changes in ambient PM sub(2.5) resulting from an array of emission control scenarios affecting 12 different combinations of sources emitting carbonaceous particles, NO sub( x ), SO sub( x ), NH sub(3), and volatile organic compounds. We perform this modeling for each of nine urban areas and one nationwide area. Upon modeling the air quality change, we then divide the total monetized health benefits by the PM sub(2.5) precursor emission reductions to generate $/ton metrics. The resulting $/ton estimates exhibit the greatest variability across certain precursors and sources such as area source SO sub( x ), point source SO sub( x ), and mobile source NH sub(3). Certain $/ton estimates, including mobile source NO sub( x ), exhibit significant variability across urban areas. Reductions in carbonaceous particles generate the largest $/ton across all locations.

We parameterized these models using existing survival estimates and data from long-term monitoring of loon productivity and abundance. Our models include deterministic, 2-stage, density-independent matrix models, yielding population growth-rate estimates (l) of 0.99 and 1.01 for intensively studied populations in our Wisconsin, USA, and New Hampshire, USA, study areas, respectively. Perturbation analysis of these models indicated that estimated growth rate is extremely sensitive to adult survival, as expected for this long-lived species. Also, we examined 20 years of count data for the 2 areas and evaluated support for a set of count-based models of population growth. We detected no temporal trend in Wisconsin, which would be consistent with fluctuation around an average equilibrium state but could also result from data limitations. For New Hampshire, the model set included varying formulations of density dependence and partitioning of stochasticity that were enabled by the annual sampling resolution. The best model for New Hampshire included density regulation of population growth and, along with the demographic analyses for both areas, provided insight into the possible importance of breeding habitat availability and the abundance of nonbreeding adults. Based on these results, we recommend that conservation organizations include nonbreeder abundance in common loon monitoring efforts and that additional emphasis be placed on identifying and managing human influences on adult loon survival.

The soil respiration rates significantly increased along a gradient of increasing watershed nitrogen (N) loads (S. alterniflora, R2 = 0.95, P = 0.0008; S. patens, R2 = 0.70, P = 0.02). As the soil respiration increased, the percent carbon (C) and N in the soil surface layer decreased in the S. alterniflora, suggesting that in part, the increased soil respiration rates are contributing to the increased turnover of labile organic matter. In contrast, there were no apparent relationships between the soil respiration rates in the high marsh and the soil C and N contents of the surface layer. However, there was a broad-scale pattern and significant inverse relationship between the high marsh soil respiration rates and the landscape belowground biomass of S. patens. As more and more salt marsh systems are subjected to increasing nutrient loads, decomposition rates of soil organic matter may increase in marsh soils leading to higher turnover rates of C and N.

With a mean concentration of 179 ng/g wet wt., whole lake trout total mercury (Hg sub(T)) concentrations ranged between 27.6 and 348 ng/g wet wt. For combined sites, 1-4 yrs, 5-6 yrs, 7-11 yrs, and 12-15 yrs lake trout mean Hg sub(T) concentrations were 73.7, 130, 212, and 280 ng/g, respectively. Forage fish species alewife (Alosa pseudoharengus), bloater (Coregonus hoyi), slimy sculpin (Cottus cognatus), deepwater sculpin (Myoxocephalus thompsoni), and rainbow smelt (Osmerus mordax) had mean Hg sub(T) concentrations of 63.8, 55.3, 36.7, 51.4, and 35.2 ng/g wet wt., respectively. With the exception of alewife, bloater, and slimy sculpin, all fish species contained approximately 100% methyl mercury (MeHg). Field bioaccumulation factors (BAF) were consistent with a Lake Michigan food chain that is more efficient at transferring MeHg to higher trophic levels than some inland lakes. This and other studies of lake trout from Lake Michigan document decreasing Hg sub(T) concentrations in lake trout from 1971 to 1985 and constant or increasing concentrations between 1985 and 2000. These observations were supported by a similar trend in Lake Michigan Hg sediment fluxes. To our knowledge, this is the most intense two year study of mercury in fish for any Great Lake or other large fresh water system and is one of the most complete studies of mercury cycling in the Lake Michigan food chain.

Results from 383 rat and 368 rabbit prenatal studies on 387 chemicals, mostly pesticides, were entered into the U.S. Environmental Protection Agency's (EPA) Toxicity Reference Database (ToxRefDB) using harmonized terminology. An initial assessment of these data was performed with the goal of profiling environmental chemicals based on maternal and fetal endpoints for anchoring in vitro data provided in the EPA's ToxCast(TM) research program. Using 30 years worth of standard prenatal studies, maternal and fetal effects were culled from the database and analyzed by target-description fields and lowest effect levels (LELs). Focusing on inter-species comparison, the complexity of fetal target organ response to maternal dosing with environmental chemicals during the period of major organogenesis revealed hierarchical relationships. Of 283 chemicals tested in both species, 53 chemicals (18.7%) had LELs on development (dLEL) that were either specific, with no maternal toxicity (mLEL), or sensitive (dLEL 150 m). The LOPC tow surveys were extensive and spatially covered much of Lake Superior (> 1300 km of towing). The LOPC was field calibrated to Lake Superior zooplankton samples collected across the years of 2004 to 2006. The volume-weighted lake- wide zooplankton biomass determined by traditional net tows to 100-m sample depth was 20.1 (+/- 7.8 SD n = 52) mg dry-weight m super(- 3). The estimates varied by depth zones within the lake, where nearshore (0-30 m) estimates were highest and highly variable. Net sites for the LOPC field calibration were removed to allow for LOPC validation with independent nets; the resulting net-based estimate 20.0 (+/- 9.3 SD n = 38) mg dry-weight m super(- 3) and LOPC lake-wide estimate 19.1 (+/- 3.3 SD) mg dry-weight m super(- 3) agreed well. Consistency across survey methods for lake-wide estimates suggested that LOPC survey data provides a comparable assessment tool to traditional nets for collecting zooplankton biomass data. We briefly compare our results with some observed historical patterns. Onshore-offshore trends in zooplankton biomass concentrations were similar to the last major lake-wide survey in 1973. The LOPC provided high resolution data on zooplankton biomass distribution. Using simultaneously collected in situ sensor data, the LOPC zooplankton biomass distributions over horizontal and vertical space can be modeled as a function of temperature and fluorescence.

Sources of exposure described include cigarettes and other forms of smoked tobacco, secondhand (environmental) tobacco smoke, several forms of smokeless tobacco, and nicotine from nicotine replacement therapy. Exposure is immense and worldwide, most of it due to smoking, but in some parts of the world and in some populations, smoking is exceeded by smokeless tobacco use. Nicotine and carbon monoxide exposure are of large concern, but cigarette smoke contains over 4000 chemical constituents and additives including known carcinogens, toxic heavy metals, and many chemicals untested for developmental toxicity. The impact of tobacco on human development will be reviewed. Fertility, conception, survival of the conceptus, most phases and aspects of development studied to date, as well as postnatal survival and health are adversely impacted by maternal tobacco use or exposure. Effects in surviving offspring are probably life-long, and are still being elucidated. It is hoped that this review will serve to keep a focus on the critical and continuing problem of tobacco use impacting human development.

Our objective was to determine the utility of satellite remote sensing to accurately detect isolated wetlands. Image segmentation and object-oriented analysis were applied to Landsat-7 imagery from January and October 2000 to map isolated wetlands in the St. Johns River Water Management District of Alachua County, Florida. Accuracy for individual isolated wetlands was determined based on the intersection of reference and remotely sensed polygons. The January data yielded producer and user accuracies of 88% and 89%, respectively, for isolated wetlands larger than 0.5 acres (0.20 ha). Producer and user accuracies increased to 97% and 95%, respectively, for isolated wetlands larger than 2 acres (0.81 ha). Recently, the Federal Geographic Data Committee recommended that all U.S. wetlands 0.5 acres (0.20 ha) or larger should be mapped using 1-m aerial photography with an accuracy of 98%. That accuracy was nearly achieved in this study using a spatial resolution that is 900 times coarser. Satellite remote sensing provides an accurate, relatively inexpensive, and timely means for classifying isolated depressional wetlands on a regional or national basis.

Since the original publication, several international groups have provided public comment on conducting the test. The extended one-generation reproductive toxicity test is now under consideration as a potential test guideline. The protocol uses a flexible approach that is markedly different from the current multigenerational guidelines. It encourages the use of toxicokinetics when setting the doses, evaluates more than one rat per sex per litter in the F1 offspring and does not necessarily require mating of the F1 to produce an F2 (F1 mating may be triggered by the presence of effects in the P0 and developing F1 rats). A number of additional reproductive endpoints, and the neurotoxicity and immunotoxicity cohorts are included. The ACSA protocol was developed with the goal of assuring that the methods are scientifically appropriate and the toxicological endpoints and exposure durations are relevant for risk assessment. Compared to existing testing strategies, the proposed approach uses substantially fewer animals, provides additional information on the neonate, juvenile and pubertal animal, and includes an estimation of human exposure potential for making decisions about the extent of testing required. In this paper, the evolution of the protocol since the 2006 publication is discussed. These changes reflect the collective input of a U.S. expert panel of government and industrial scientist convened in 2007 and discussions of an OECD expert group held in Paris, France (October, 2008).

Our objectives were to quantify the relationships among summer habitat conditions, coho salmon density, and coho salmon parr abundance and weight across an extensive stream network over 3 years. We used hierarchical linear models to assess the factors influencing coho salmon weight and abundance at the levels of individual fish (fork length and parasite burden), habitat unit (surface area, cover, and density), reach (temperature and density) and stream (total nitrogen, soluble reactive phosphorus, and discharge). Habitat-unit-level surface area and stream-level minimum discharge were important predictors of both the abundance and weight of coho salmon parr. An area discharge interaction term was also important in models of weight and reflected network-level patterns of the highest abundances and highest parr condition in the middle portions of the basin. In these locations, streamflow, habitat area, and temperature were moderate compared with the warmer, higher-discharge downstream reaches and cooler, lower-discharge (or even intermittent) upstream reaches. We conclude that in the study basin coho salmon parr weight was limited by habitat unit density and minimum summer discharge in the headwaters and abundance was limited primarily by space (pool area) in the headwaters and warm summer temperatures in the lower portions of the basin.

Two types of market structure are considered: perfect competition and Cournot oligopoly. We find that output, abatement costs and the number of firms are higher under credit trading. Allowing trade between permit-trading and credit-trading sectors may increase welfare. With perfect competition, permit trading always leads to higher welfare than credit trading. With imperfect competition, credit trading may outperform permit trading. Environmental policy can lead to exit, but also to entry of firms. Entry and exit have a profound impact on the performance of the schemes, especially under imperfect competition. We find that it may be impossible to implement certain levels of total industry emissions. Under credit trading several levels of the relative standard can achieve the same total level of emissions.

Sites were located across three levels of livestock grazing intensity and three levels of selective logging intensity within the most extensive habitat type, Corymbia citriodora-dominant forest. We recorded a high rate of incidence and large numbers of the hyper-aggressive noisy miner Manorina melanocephala (Passeriformes: Meliphagidae) at the majority of our survey sites, a phenomenon rarely reported in non-cleared landscapes. As shown by numerous studies in fragmented landscapes, the distribution of this species in our study had a substantial negative effect upon the distribution of small passerine species. Noisy miners exerted the strongest influence upon small passerine abundance, and masked any forest management effects. However, key habitat features important for small passerines were identified, including a relatively high density of large trees and stems in the midstorey. Selective logging appeared to exert a minimal effect upon noisy miner abundance, whereas grazing intensity had a profound, positive influence. Noisy miners were most abundant in intensively grazed forest with minimal midstorey and a low volume of coarse woody debris. Higher road density in the forest landscape also corresponded with increased numbers of noisy miners. Reduction in grazing pressure in Brigalow Belt forests has the potential to benefit small passerine assemblages across large areas through moderating noisy miner abundance. The strong relationship between noisy miners and small passerines suggests that noisy miner abundance could act as an easily measured indicator of forest condition, potentially contributing to monitoring of forest management outcomes.

After 1-, 2- and 3-h incubation at 37C, mRNA was extracted from the cells and gene expression of two host genes, c-jun and c-fos, quantified. Aeromonas isolates which were pathogenic in the neonatal mouse model demonstrated up-regulation of c-jun and c-fos compared to avirulent isolates.Conclusions: Human cell culture results showed that c-jun and c-fos were predictive of Aeromonas virulence.Significance and Impact of the Study: An Aeromonas relative virulence scale is proposed for use in the testing of Aeromonas drinking water isolates.

Indeed, their presence suggests that the metabolism of ingested arsenic is more complex than previously thought. Recent reports have shown that thiolated arsenicals can be produced by the anaerobic microflora of the mouse cecum, suggesting that metabolism prior to systemic absorption may be a significant determinant of the pattern and extent of exposure to various arsenic-containing species. Here, we examined the metabolism of super(3) super(4)S labeled dimethylthioarsinic acid ( super(3) super(4)S-DMTA super(V)) by the anaerobic microflora of the mouse cecum using HPLC-ICP-MS and HPLC-ESI-MS/MS to monitor for the presence of various oxo- and thioarsenicals. The use of isotopically enriched super(3) super(4)S-DMTA super(V) made it possible to differentiate among potential metabolic pathways for production of the trimethylarsine sulfide (TMAS super(V)). Upon in vitro incubation in an assay containing anaerobic microflora of mouse cecum, super(3) super(4)S-DMTA super(V) underwent several transformations. Labile super(3) super(4)S was exchanged with more abundant super(3) super(2)S to produce super(3) super(2)S-DMTA super(V), a thiol group was added to yield DMDTA super(V), and a methyl group was added to yield super(3) super(4)S-TMAS super(V). Because incubation of super(3) super(4)S-DMTA super(V) resulted in the formation of super(3) super(4)S-TMAS super(V), the pathway for its formation must preserve the arsenic-sulfur bond. The alternative metabolic pathway postulated for formation of TMAS super(V) from dimethylarsinic acid (DMA super(V)) would proceed via a dimethylarsinous acid (DMA super(I) super(I) super(I)) intermediate and would necessitate the loss of super(3) super(4)S label. Structural confirmation of the metabolic product was achieved using HPLC-ESI-MS/MS. The data presented support the direct methylation of DMTA super(V) to TMAS super(V). Additionally, the detection of isotopically pure super(3) super(4)S-TMAS super(V) raises questions about the sulfur exchange properties of TMAS super(V) in the cecum material. Therefore, super(3) super(4)S-TMAS super(V) was incubated and the exchange was monitored with respect to time. The data suggest that the As-S bond associated with TMAS super(V) is less labile than the As-S bond associated with DMTA super(V).

We studied the result of a natural disaster when one-third of a forested nature preserve was destroyed by an F3 tornado. Populations of two abundant species of small mammals, Peromyscus maniculatus and P. leucopus, were monitored in both disturbed and undisturbed habitats. We used an X-ray technique to measure developmental instability as indicated by fluctuating asymmetry (FA) in cranial and skeletal features of live animals. FA in femur length was higher in disturbed habitat for P. leucopus but was higher in undisturbed habitat for P. maniculatus. This difference in developmental instability mirrors differences in habitat preference between these species: P. leucopus prefers forest habitat and P. maniculatus prefers open, herbaceous habitat. These results were not explained by either food availability or body condition, both of which were higher in the disturbed habitat suggesting higher quality for this habitat.

In addition to human influences on the quality of surface water, a cattle grazing is a widespread and persistent ecological stressor in the Western United States. Cattle may affect surface water quality directly by depositing nutrients and bacteria, and indirectly by damaging stream banks or removing vegetation cover, which may lead to increased sediment loads. This study used the State of Oregon surface water data to determine the likelihood of animal pathogen presence using enterococci and analyzed the spatial distribution and relationship of biotic (enterococci) and abiotic (nitrogen and phosphorous) surface water constituents to landscape metrics and others (e.g. human use, percent riparian cover, natural covers, grazing, etc.). We used a grazing potential index (GPI) based on proximity to water, land ownership and forage availability. Mean and variability of GPI, forage availability, stream density and length, and landscape metrics were related to enterococci and many forms of nitrogen and phosphorous in standard and logistic regression models. The GPI did not have a significant role in the models, but forage related variables had significant contribution. Urban land use within stream reach was the main driving factor when exceeding the threshold (.35cfu/100ml), agriculture was the driving force in elevating enterococci in sites where enterococci concentration was <35cfu/100ml. Landscape metrics related to amount of agriculture, wetlands and urban all contributed to increasing nutrients in surface water but at different scales. The probability of having sites with concentrations of enterococci above the threshold was much lower in areas of natural land cover and much higher in areas with higher urban land use within 60m of stream. A 1% increase in natural land cover was associated with a 12% decrease in the predicted odds of having a site exceeding the threshold. Opposite to natural land cover, a one unit change in each of manmade barren and urban land use led to an increase of the likelihood of exceeding the threshold by 73%, and 11%, respectively. Change in urban land use had a higher influence on the likelihood of a site exceeding the threshold than that of natural land cover.

Altered expression of AS3MT in cultured human cells controls arsenic methylation phenotypes, suggesting a critical role in arsenic metabolism. Because methylated arsenicals mediate some toxic or carcinogenic effects linked to inorganic arsenic exposure, studies of the fate and effects of arsenicals in mice which cannot methylate arsenic could be instructive. This study compared retention and distribution of arsenic in As3mt knockout mice and in wild-type C57BL/6 mice in which expression of the As3mt gene is normal. Male and female mice of either genotype received an oral dose of 0.5 mg of arsenic as arsenate per kg containing [73As]-arsenate. Mice were radioassayed for up to 96 h after dosing; tissues were collected at 2 and 24 h after dosing. At 2 and 24 h after dosing, livers of As3mt knockouts contained a greater proportion of inorganic and monomethylated arsenic than did livers of C57BL/6 mice. A similar predominance of inorganic and monomethylated arsenic was found in the urine of As3mt knockouts. At 24 h after dosing, As3mt knockouts retained significantly higher percentages of arsenic dose in liver, kidneys, urinary bladder, lungs, heart, and carcass than did C57BL/6 mice. Whole body clearance of [73As] in As3mt knockouts was substantially slower than in C57BL/6 mice. At 24 h after dosing, As3mt knockouts retained about 50% and C57BL/6 mice about 6% of the dose. After 96 h, As3mt knockouts retained about 20% and C57BL/6 mice retained less than 2% of the dose. These data confirm a central role for As3mt in the metabolism of inorganic arsenic and indicate that phenotypes for arsenic retention and distribution are markedly affected by the null genotype for arsenic methylation, indicating a close linkage between the metabolism and retention of arsenicals.

Data were collected on 7 cruises from 2005 to 2007, and spatially-averaged estimates of phytoplankton and light variables were calculated for the study area using Voronoi polygon normalization. Shelf-wide phytoplankton production ranged from 0.47 to 1.75mg Cm super(-) super(2)d super(-) super(1) across the 7 cruises. Shelf-wide average light attenuation (k sub(d)) ranged from 0.19-1.01m super(-) super(1) and strongly covaried with freshwater discharge from the Mississippi and Atchafalaya Rivers (R super(2)=0.67). Interestingly, we observed that the euphotic zone (as defined by the 1% light depth) extended well below the pycnocline and to the bottom across much of the shelf. Shelf-wide average chlorophyll a (chl a) concentrations ranged from 1.4 to 5.9mgm super(-) super(3) and, similar to k sub(d), covaried with river discharge (R super(2)=0.83). Also, chl a concentrations were significantly higher in plume versus non-plume regions of the shelf. When integrated through the water-column, shelf-wide average chl a ranged from 26.3 to 47.6mgm super(-) super(2), but did not covary with river discharge, nor were plume versus non-plume averages statistically different. The high integrated chl a in the non-plume waters resulted from frequent sub-pycnocline chl a maxima. Phytoplankton production rates were highest in the vicinity of the Mississippi River bird's foot delta, but as with integrated chl a were not statistically different in plume versus non-plume waters across the rest of the shelf. Based on the vertical distribution of light and chl a, a substantial fraction of phytoplankton production occurred below the pycnocline, averaging from 25% to 50% among cruises. These results suggest that freshwater and nutrient inputs regulate shelf-wide k sub(d) and, consequently, the vertical distribution of primary production. The substantial below-pycnocline primary production we observed has not been previously quantified for this region, but has important implications about the formation and persistence of hypoxia on the Louisiana continental shelf.

AN - 67396769; 19539801 AB - Mutagen X (MX) is a chlorinated furanone that accounts for more of the mutagenic activity of drinking water than any other disinfection by-product. It is one of the most potent base-substitution mutagens in the Salmonella (Ames) mutagenicity assay, producing primarily GC to TA mutations in TA100. MX does not produce stable DNA adducts in cellular or acellular DNA. However, theoretical calculations predict that it might induce abasic sites, which it does in supercoiled plasmid DNA but not in rodents. To investigate the ability of MX to induce abasic sites in cellular DNA, we used an aldehydic site assay to detect abasic sites in DNA from Salmonella TA100 cells treated for 1.5 h with MX. At 0, 2.3, and 4.6 microM, MX induced mutant frequencies (revertants/10(6) survivors) and percent survivals of 2 (100%), 14.9 (111%), and 59.3 (45%), respectively. The frequencies of abasic sites (sites/10(5) nucleotides) for the control and two concentrations were 5.9, 6.2, and 9.7, respectively, with the frequency at the highest concentration being significant (P<0.001). These results provide some evidence for the ability of MX to induce abasic sites in cellular DNA. However, the lack of a dose response makes it unclear whether this DNA damage underlies the mutagenic activity of MX.

10238275 AB - Epidemiological studies suggest that chronic exposure to inorganic arsenic is associated with cancer of the skin, urinary bladder and lung as well as the kidney and liver. Previous experimental studies have demonstrated increased incidence of liver, lung, ovary, and uterine tumors in mice exposed to 85ppm (8mg/kg) inorganic arsenic during gestation. To further characterize age susceptibility to arsenic carcinogenesis we administered 85ppm inorganic arsenic in drinking water to C3H mice during gestation, prior to pubescence and post-pubescence to compare proliferative lesion and tumor outcomes over a one-year exposure period. Inorganic arsenic significantly increased the incidence of hyperplasia in urinary bladder (48%) and oviduct (36%) in female mice exposed prior to pubescence (beginning on postnatal day 21 and extending through one year) compared to control mice (19 and 5%, respectively). Arsenic also increased the incidence of hyperplasia in urinary bladder (28%) of female mice continuously exposed to arsenic (beginning on gestation day 8 and extending though one year) compared to gestation only exposed mice (0%). In contrast, inorganic arsenic significantly decreased the incidence of tumors in liver (0%) and adrenal glands (0%) of male mice continuously exposed from gestation through one year, as compared to levels in control (30 and 65%, respectively) and gestation only (33 and 55%, respectively) exposed mice. Together, these results suggest that continuous inorganic arsenic exposure at 85ppm from gestation through one year increases the incidence and severity of urogenital proliferative lesions in female mice and decreases the incidence of liver and adrenal tumors in male mice. The paradoxical nature of these effects may be related to altered lipid metabolism, the effective dose in each target organ, and/or the shorter one-year observational period.

AN - 734017606; 19639652 AB - It is well known that a variety of teratogens induce neural tube defects in animals; however, less is known about proteins that play a role in protecting embryos from teratogen-induced neural tube defects. Previously, our laboratory has shown that embryos overexpressing the 70-Da heat shock proteins (HSPs) Hspa1a and Hspa1b were partially protected from the deleterious effects of exposure to hyperthermia in vitro. In the present studies, we have used a transgenic mouse in which both of the stress-inducible HSPs Hspa1a and Hspa1b were deleted by homologous recombination. Time-mated Hspa1a/a1b(-/-) (KO) and wildtype (WT) mice were exposed to hyperthermia in vivo on gestational day 8.5. Results show that 52% of the gestational day 15 fetuses from KO litters were exencephalic, whereas only 20% of WT fetuses were affected. In addition, 6% of treated KO fetuses also exhibited eye defects (microphthalmia and anopthalmia), defects not observed in WT fetuses exposed to hyperthermia. Lysotracker red staining and caspase-3 enzyme activity were examined within 10 hours after exposure to hyperthermia, and significantly greater levels of apoptosis and enzyme activity were observed in the KO embryos compared with WT embryos. These results show that embryos lacking the Hspa1a and Hspa1b genes are significantly more sensitive to hyperthermia-induced neural tube and eye defects, and this increased sensitivity is correlated with increased amounts of apoptosis. Thus, these results also suggest that Hspa1a and Hspa1b play an important role in protecting embryos from hyperthermia-induced congenital defects, possibly by reducing hyperthermia-induced apoptosis.

AN - 67665089; 19772717 AB - Chlorine has been widely used to kill disease-causing microbes in drinking water. During the disinfection process, organic and inorganic material in source waters can combine with chlorine and certain other chemical disinfectants to form disinfection by-products. The kind of disinfectant used can produce different types and levels of disinfectant byproducts in the drinking water, such as trihalomethanes and haloacetic acids (5HAAs). Currently, USEPA Method 552 utilizes a methyl tert-butyl ether extraction and diazomethane derivatization of HAAs and phenolic disinfectant by-products, and a gas chromatograph equipped with a capillary column to perform the separation of methyl-haloacetates and anisoles. To detect, gas chromatography and electron capture detector are used. This article demonstrates a simple method using direct injection ion chromatography hyphenated with mass spectrometry for the analysis of 5HAAs.

AN - 67639199; 19731678 AB - This paper presents the first National Emissions Inventory (NEI) of fine particulate matter (PM2.5) that includes the full suite of PM2.5 trace elements (atomic number > 10) measured at ambient monitoring sites across the U.S. PM2.5 emissions in the NEI were organized and aggregated into a set of 84 source categories for which chemical speciation profiles are available (e.g., Unpaved Road Dust Agricultural Soil, Wildfires). Emission estimates for ten metals classified as Hazardous Air Pollutants (HAP) were refined using data from a recent HAP NEI. All emissions were spatially gridded, and U.S. emissions maps for dozens of trace elements (e.g., Fe, Ti) are presented for the first time. Nationally, the trace elements emitted in the highest quantities are silicon (3.8 x 10(5) ton/yr), aluminum (1.4 x 10(5) ton/yr), and calcium (1.3 x 10(5) ton/yr). Our chemical characterization of the PM2.5 inventory shows that most of the previously unspeciated emissions are comprised of crustal elements, potassium, sodium, chlorine, and metal-bound oxygen. This work also reveals that the largest PM2.5 sources lacking specific speciation data are off-road diesel-powered mobile equipment, road construction dust, marine vessels, gasoline-powered boats, and railroad locomotives.

AN - 67629557; 19708059 AB - This update (Version 2) of the Terminology of Developmental Abnormalities in Common Laboratory Mammals (Version 1) by Wise et al. (1997) incorporates improvements and enhancements to both content and organization of the terminology, to enable greater flexibility in its application, while maintaining a consistent approach to the description of findings. The revisions are the result of an international collaboration among interested organizations, advised by individual experts and the outcomes of several workshops. The terminology remains organized into tables under the broad categories of external, visceral, and skeletal observations, following the manner in which data are typically collected and recorded in developmental toxicity studies. This arrangement of the tables, as well as other information provided in appendices, is intended to facilitate the process of specimen evaluation at the laboratory bench level. Only the commonly used laboratory mammals (i.e., rats, mice, rabbits) are addressed in the current terminology tables. The inclusion of other species that are used in developmental toxicity testing, such as primates, is considered outside the scope of the present update. Similarly, categorization of findings as, for example, "malformation" or "variation" remains unaddressed, in accordance with the overall principle that the focus of this document is descriptive terminology and not diagnosis/interpretation. The skeletal terms have been augmented to accommodate cartilage findings. Copyright (c) 2009 Wiley-Liss, Inc. JF - Birth defects research.

AN - 67614113; 19422270 AB - As part of a research effort examining system-wide responses of the hypothalamic-pituitary-gonadal (HPG) axis in fish to endocrine-active chemicals (EACs) with different modes of action, zebrafish (Danio rerio) were exposed to 25 or 100 microg/L of the aromatase inhibitor fadrozole for 24, 48, or 96 h. Global transcriptional response in brain and ovarian tissue of fish exposed to 25 microg/L of fadrozole was compared to that in control fish using a commercially available, 22,000-gene oligonucleotide microarray. Transcripts altered in brain were functionally linked to differentiation, development, DNA replication, and cell cycle. Additionally, multiple genes associated with the one-carbon pool by folate pathway (KEGG 00670) were significantly up-regulated. Transcripts altered in ovary were functionally linked to cell-cell adhesion, extracellular matrix, vasculogenesis, and development. Promoter motif analysis identified GATA-binding factor 2, Ikaros 2, alcohol dehydrogenase gene regulator 1, myoblast-determining factor, and several heat shock factors as being associated with coexpressed gene clusters that were differentially expressed following exposure to fadrozole. Based on the transcriptional changes observed, it was hypothesized that fadrozole elicits neurodegenerative stress in brain tissue and that fish cope with this stress through proliferation of radial glial cells. Additionally, it was hypothesized that changes of gene expression in the ovary of fadrozole-exposed zebrafish reflect disruption of oocyte maturation and ovulation because of impaired vitellogenesis. These hypotheses and others derived from the microarray results provide a foundation for future studies aimed at understanding responses of the HPG axis to EACs and other chemical stressors.

AN - 67532243; 19452204 AB - Common decision support tools and a growing body of knowledge about ecological recovery can help inform and guide large state and federal restoration programs affecting thousands of impaired waters. Under the federal Clean Water Act (CWA), waters not meeting state Water Quality Standards due to impairment by pollutants are placed on the CWA Section 303(d) list, scheduled for Total Maximum Daily Load (TMDL) development, and ultimately restored. Tens of thousands of 303(d)-listed waters, many with completed TMDLs, represent a restoration workload of many years. State TMDL scheduling and implementation decisions influence the choice of waters and the sequence of restoration. Strategies that compare these waters' recovery potential could optimize the gain of ecological resources by restoring promising sites earlier. We explored ways for states to use recovery potential in restoration priority setting with landscape analysis methods, geographic data, and impaired waters monitoring data. From the literature and practice we identified measurable, recovery-relevant ecological, stressor, and social context metrics and developed a restorability screening approach adaptable to widely different environments and program goals. In this paper we describe the indicators, the methodology, and three statewide, recovery-based targeting and prioritization projects. We also call for refining the scientific basis for estimating recovery potential.

AN - 67499192; 19460944 AB - Class III alcohol dehydrogenase (ADH3), also termed formaldehyde dehydrogenase or S-nitrosoglutathione reductase, plays a critical role in the enzymatic oxidation of formaldehyde and reduction of nitrosothiols that regulate bronchial tone. Considering reported associations between formaldehyde vapor exposure and childhood asthma risk, and thus potential involvement of ADH3, we reviewed the ontogeny, distribution, and regulation of mammalian ADH3. Recent studies indicate that multiple biological and chemical stimuli influence expression and activity of ADH3, including the feedback regulation of nitrosothiol metabolism. The levels of ADH3 correlate with, and potentially influence, bronchial tone; however, data gaps remain with respect to the expression of ADH3 during postnatal and early childhood development. Consideration of ADH3 function relative to the respiratory effects of formaldehyde, as well as to other chemical and biological exposures that might act in an additive or synergistic manner with formaldehyde, might be critical to gain better insight into the association between formaldehyde exposure and childhood asthma.

AN - 67479534; 19482887 AB - In the rat, some phthalates alter sexual differentiation at relatively low dosage levels by altering fetal Leydig cell development and hormone synthesis, thereby inducing abnormalities of the testis, gubernacular ligaments, epididymis, and other androgen-dependent tissues. In order to define the dose-response relationship between di(2-ethylhexyl) phthalate (DEHP) and the Phthalate Syndrome of reproductive alterations in F1 male rats, Sprague-Dawley (SD) rat dams were dosed by gavage from gestational day 8 to day 17 of lactation with 0, 11, 33, 100, or 300 mg/kg/day DEHP (71-93 males per dose from 12 to 14 litters per dose). Some of the male offspring continued to be exposed to DEHP via gavage from 18 days of age to necropsy at 63-65 days of age (PUB cohort; 16-20/dose). Remaining males were not exposed after postnatal day 17 (in utero-lactational [IUL] cohort) and were necropsied after reaching full maturity. Anogenital distance, sperm counts and reproductive organ weights were reduced in F1 males in the 300 mg/kg/day group and they displayed retained nipples. In the IUL cohort, seminal vesicle weight also was reduced at 100 mg/kg/day. In contrast, serum testosterone and estradiol levels were unaffected in either the PUB or IUL cohorts at necropsy. A significant percentage of F1 males displayed one or more Phthalate Syndrome lesions at 11 mg/kg/day DEHP and above. We were able to detect effects in the lower dose groups only because we examined all the males in each litter rather than only one male per litter. Power calculations demonstrate how using multiple males versus one male/litter enhances the detection of the effects of DEHP. The results at 11 mg/kg/day confirm those reported from a National Toxicology Program multigenerational study which reported no observed adverse effect levels-lowest observed adverse effect levels of 5 and 10 mg/kg/day DEHP, respectively, via the diet.

AN - 67478332; 19423681 AB - The mode of action for the reproductive toxicity of some triazole antifungals has been characterized as an increase in serum testosterone and hepatic response, and reduced insemination and fertility indices. In order to refine our mechanistic understanding of these potential modes of action, gene expression profiling was conducted on liver and testis from male Wistar Han IGS rats exposed to myclobutanil (500, 2000 ppm), propiconazole (500, 2500 ppm), or triadimefon (500, 1800 ppm) from gestation day six to postnatal day 92. Gene expression profiles indicated that all three triazoles significantly perturbed the fatty acid, steroid, and xenobiotic metabolism pathways in the male rat liver. In addition, triadimefon modulated expression of genes in the liver from the sterol biosynthesis pathway. Although expression of individual genes were affected, there were no common pathways modulated by all three triazoles in the testis. The pathways identified in the liver included numerous genes involved in phase I-III metabolism (Aldh1a1, Cyp1a1, Cyp2b2, Cyp3a1, Cyp3a2, Slco1a4, Udpgtr2), fatty acid metabolism (Cyp4a10, Pcx, Ppap2b), and steroid metabolism (Ugt1a1, Ugt2a1) for which expression was altered by the triazoles. These differentially expressed genes form part of a network involving lipid, sterol, and steroid homeostatic pathways regulated by the constitutive androstane (CAR), pregnane X (PXR), peroxisome proliferator-activated alpha, and other nuclear receptors in liver. These relatively high dose and long-term exposures to triazole antifungals appeared to perturb fatty acid and steroid metabolism in the male rat liver predominantly through the CAR and PXR signaling pathways. These toxicogenomic effects describe a plausible series of key events contributing to the disruption in steroid homeostasis and reproductive toxicity of select triazole antifungals.

AN - 67391942; 19467697 AB - Passive ambient air sampling for nitrogen dioxide (NO(2)) and volatile organic compounds (VOCs) was conducted at 25 school and two compliance sites in Detroit and Dearborn, Michigan, USA during the summer of 2005. Geographic Information System (GIS) data were calculated at each of 116 schools. The 25 selected schools were monitored to assess and model intra-urban gradients of air pollutants to evaluate impact of traffic and urban emissions on pollutant levels. Schools were chosen to be statistically representative of urban land use variables such as distance to major roadways, traffic intensity around the schools, distance to nearest point sources, population density, and distance to nearest border crossing. Two approaches were used to investigate spatial variability. First, Kruskal-Wallis analyses and pairwise comparisons on data from the schools examined coarse spatial differences based on city section and distance from heavily trafficked roads. Secondly, spatial variation on a finer scale and as a response to multiple factors was evaluated through land use regression (LUR) models via multiple linear regression. For weeklong exposures, VOCs did not exhibit spatial variability by city section or distance from major roads; NO(2) was significantly elevated in a section dominated by traffic and industrial influence versus a residential section. Somewhat in contrast to coarse spatial analyses, LUR results revealed spatial gradients in NO(2) and selected VOCs across the area. The process used to select spatially representative sites for air sampling and the results of coarse and fine spatial variability of air pollutants provide insights that may guide future air quality studies in assessing intra-urban gradients.

Tonkin and Larson (2002) and Brochu and Marcotte (2003) describe a mapping-based method for estimating the capture zone of pumped wells, developed by combining universal kriging (kriging with a trend) with analytical expressions that describe the response of the potentiometric surface to certain applied stresses. This Methods Note describes (a) expansions to the technique described by Tonkin and Larson (2002); (b) the concept of the capture frequency map (CFM), a technique that combines information from multiple capture zone maps into a single depiction of capture; (c) the development of a graphical user interface to facilitate the use of the methods described; and (d) the integration of these programs within the MapWindow geographic information system environment.

Model solids were used in this study to evaluate different solutions designed to extract arsenic from relatively labile solid phases. Sequential and single-step extractions were conducted to evaluate the selectivity of these extraction solutions for differentiating arsenic associated with iron (hydr)oxides and iron sulfides. Extraction phases were categorized as 1) MgCl (sub 2) -extractable, 2) phosphate-extractable, 3) ascorbate-extractable, and 4) HCl-extractable when the procedure is applied in sequence. Arsenic, iron, and sulfur concentrations were compared between the single-step and sequential extractions. Additionally, phosphate extractions were conducted at three pH values for comparison purposes. Application of the extraction protocol to orpiment of varying crystallinity and crystalline arsenopyrite indicated that these phases have limited solubility in the extractant solutions. Extraction with ascorbate at circumneutral pH appears to target dissolution of poorly crystalline iron (hydr)oxides and is largely selective for extracting arsenic associated with this phase. Tests of the ascorbate extraction solution on sediment samples previously characterized for mineralogy and solid phase arsenic speciation by X-ray absorption spectroscopy reveal the utility of ascorbate for differentiating arsenic associated with poorly crystalline iron (hydr)oxides and iron sulfides. Results from tests in which samples were dried by different approaches or were subjected to air exposure prior to or during extraction demonstrate the importance of sample handling on the outcome of extraction protocols.

A comparison of telephone, mail, and in-person treatments in contingent valuation surveys AN - 37201251; 3899961 AB - The choice of survey mode in contingent valuation research has long been debated in the literature. However, there is limited evidence as to how mode impacts behavior. Using an identical survey administered with telephone, mail, and in-person interviews, this is the first research to examine mode effects using all three commonly employed modes in contingent valuation research. Results show that there is some evidence of social desirability bias in the telephone survey. In addition, the role of income in the decision-making process is an important consideration.

We applied a previously developed index of urbanization to a sample of 10 watersheds selected at random from a set of 30 watersheds whose boundaries lay within the borders of Rhode Island, USA. The index of urbanization in our sample watersheds ranged over more than an order of magnitude and increased with increasing amount of urban land use in the watersheds (r super(2)=0.51, F=8.22, P=0.02). The density of isolated wetlands in the watersheds averaged 1.93c0.21 wetlands km super(-2) and comprised 38.2c1.77% of all wetlands. Isolated wetlands were smaller than those connected to other waters (non-isolated), and accounted for 6.01-16.5% of the total wetland area in the watersheds. The area of isolated wetlands as a percent of all wetland area significantly increased with increasing watershed urbanization (r super(2)=0.62, F=12.9, P=0.007). Isolated wetlands were predominantly deciduous forested wetlands, and urban land cover in the 50m buffer surrounding isolated wetlands was significantly higher than in the 50m surrounding non-isolated wetlands. The proportion of urban land cover was greater in a 150 than a 50m buffer surrounding the wetlands. Our results suggest that an increase in the index of urbanization of 50 will result in 7% of the watershed's wetlands being lost from federal protection. These findings indicate that the process of urbanization, along with accompanying habitat fragmentation, may result in an increase in the vulnerability of wetlands to loss and degradation and therefore has implications for the management and conservation of geographically isolated wetlands.

However, the goal with any approach is to determine the minimum level of effort necessary to reach some specific level of confidence in the assessment. In the Ohio River, condition is estimated and reported primarily at the level of pools defined by lock and dam structures. The goal of this study was to determine the minimum level of sampling effort required to adequately characterize pools in the Ohio River for the purpose of bioassessment. We followed two approaches to estimating required sampling effort using fish assemblage data from a long-term intensive survey across a number of Ohio River pools. First, we estimated the number of samples beyond which variation in the multimetric Ohio River Fish Index (ORFIn) leveled off. Then, we determined the number of samples necessary to collect approximately 90% of the fish species observed across all samples collected within the pool. For both approaches, approximately 15 samples were adequate to reduce variation in IBI scores to acceptable levels and to capture 90% of observed species in a pool. The results of this evaluation provide a basis not only for the Ohio River Valley Water Sanitation Commission (ORSANCO) but also states and other basin commissions to develop sampling designs for bioassessment that ensure adequate sampling of all assessment units.

To address some of these challenges, the National Research Council (NRC) developed a new vision for toxicity testing. Although the report focused only on toxicity testing, it recognized that exposure science will play a crucial role in a new risk-based framework. Objective In this commentary we expand on the important role of exposure science in a fully integrated system for risk assessment. We also elaborate on the exposure research needed to achieve this vision. Discussion Exposure science, when applied in an integrated systems approach for risk assessment, can be used to inform and prioritize toxicity testing, describe risks, and verify the outcomes of testing. Exposure research in several areas will be needed to achieve the NRC vision. For example, models are needed to screen chemicals based on exposure. Exposure, dosearesponse, and biological pathway models must be developed and linked. Advanced computational approaches are required for dose reconstruction. Monitoring methods are needed that easily measure exposure, internal dose, susceptibility, and biological outcome. Finally, population monitoring studies are needed to interpret toxicity test results in terms of real-world risk. Conclusion This commentary is a call for the exposure community to step up to the challenge by developing a predictive science with the knowledge and tools for moving into the 21st century.

The sampling campaigns were performed at two U.S. Department of Energy (DOE) demonstration sites where brominated PAC was being injected for control of mercury emissions. The results of the sampling campaigns showed that injection of the brominated PAC upstream of the electrostatic precipitator (ESP) did not increase the emissions of total and Toxic EQuivalent (TEQ) chlorinated and brominated dioxin compounds. Rather, the data suggested the sorbent may capture these compounds and reduce their concentration in the flue gas stream. This effect, when seen, was small, and independent of the type of plant emission controls, temperature at the point of injection, or fuel-chlorine content. The addition of the brominated PAC sorbent resulted in slight increases the total content of chlorinated dioxins and furan in the particulate matter (ash) collected in the ESP, but did not increase its overall toxicity.

Gypsum wallboard (porous) and glass slide (non-porous) building materials were used. Two fungi organisms, two bacteria organisms and two levels of relative humidity (RH) were tested. Increased humidity and non-porous surface exposure were found to increase the biocidal capability of high levels of ozone. The results of this study indicate that even at relatively high concentrations of ozone, it is difficult to get significant reductions of microorganisms on surfaces, especially on porous materials.

Accordingly, the treatments (three replicates each) differed in base flow between events and in the rise to, fall from, and duration of peak flow during simulated storm hydrographs, which were triggered by real rain events occurring outside over a 96-day period from summer to fall, 2005. Incident irradiance, initial substrate quality, and water quality were similar between treatments. Sampling was designed to study the interactions among the treatment flow dynamics, sediment transport processes, streambed nutrients, and biotic structure and function. What appeared most important to the overall structure and function of the mesocosm ecosystems beyond those changes resulting from natural seasonality were (1) the initial mass of fines that infiltrated into the gravel bed, which had a persistent effect on nitrogen biogeochemistry and (2) the subsequent fine sediment accumulation rate, which was unexpectedly similar between treatments, and affected the structure of the macroinvertebrate community equally as the experiment progressed. Invertebrate taxa preferring soft beds dominated when the gravel was comprised of 5-10% fines. The dominant invertebrate algal grazer had vacated the channels when fines exceeded 15%, but this effect could not be separated from what appeared to be a seasonal decline in insect densities over the course of the study. Neither hydrograph treatment allowed for scour or other potential for flushing of fines. This demonstrated the potential importance of interactions between hydrology and fine sediment loading dynamics on stream ecosystems in the absence of flows that would act to mobilize gravel beds.

In this paper, we assess (1) how the spatial distribution of NO sub(3)-N concentrations varies across a dense network of nonnested catchments and (2) how relationships between multiple landscape factors [within whole catchments and hydrologically sensitive areas (HSAs) of the catchments] and stream NO sub(3)-N are expressed under a variety of annual conditions. Stream NO sub(3)-N data were collected during two synoptic sampling events across >55 tributaries and two synoptic sampling periods with >11 tributaries during summer low flow periods. Sample tributaries drain mixed land cover watersheds ranging in size from 0.150 to 312 km super(2) and outlet directly to Cayuga Lake, New York. Changes in NO sub(3)-N concentration ratios between each sampling event suggest a high degree of spatial heterogeneity in catchment response across the Cayuga Lake Watershed, ranging from 0.230 to 61.4. Variations in NO sub(3)-N concentrations within each of the large synoptic sampling events were also high, ranging from 0.040 to 8.7 mg NO sub(3)-N/l (March) and 0.090 to 15.5 mg NO sub(3)-N/l (October). Although Pearson correlation coefficients suggest that this variability is related to multiple landscape factors during all four sampling events, partial correlations suggest percentage of row crops in the catchments as the only similar factor in March and October and catchment area as the only factor during summer low flows. Further, the strength of the relationships is typically lower in the HSAs of catchment. Advancing current understanding of such variations and relationships to landscape factors across multiple catchments - and under a variety of biogeochemical and hydrological conditions - is important, as (1) nitrate continues to be employed as an indicator of regional aquatic ecosystem health and services and (2) a unified framework approach for understanding individual catchment processes is a rapidly evolving focus for catchment-based science and management.

Using gridded output of atmospheric deposition from the Community Multiscale Air Quality (CMAQ) model, the Watershed Deposition Tool (WDT) calculates average per unit area and total deposition to selected watersheds and subwatersheds. CMAQ estimates the wet and dry deposition for all of its gaseous and particulate chemical species, including ozone, sulfur species, nitrogen species, secondary organic aerosols, and hazardous air pollutants at grid scale sizes ranging from 4 to 36 km. An overview of the CMAQ model is provided. The somewhat specialized format of the CMAQ files is not easily imported into standard spatial analysis tools. The WDT provides a graphical user interface that allows users to visualize CMAQ gridded data and perform further analyses on selected watersheds or simply convert CMAQ gridded data to a shapefile for use in other programs. Shapefiles for the 8-digit (cataloging unit) hydrologic unit code polygons for the United States are provided with the WDT; however, other user-supplied closed polygons may be used. An example application of the WDT for assessing the contributions of different source categories to deposition estimates, the contributions of wet and dry deposition to total deposition, and the potential reductions in total nitrogen deposition to the Albemarle-Pamlico basin stemming from future air emissions reductions is used to illustrate the WDT capabilities.

We calculate the seasonal and annual spatial variations of contemporary inorganic atmospheric N deposition loading to multi-scale watersheds across New York State using numerous monitoring datasets of precipitation and ambient atmospheric N concentrations. Our models build upon and refine previous efforts estimating the spatial distribution of N deposition. Estimates of total inorganic wet deposition (NH4-N + NO3-N) across New York ranged from 4.7 to 10.5kg ha-1 yr-1 under contemporary conditions (averaged 2002-2004), and both seasonal and annual predicted rates of inorganic N deposition (NH4-N, NO3-N, and total) fit relatively well with that of observed measurements. Our results suggest that 'hot spots' of N deposition are, for the most part, spatially distributed according to geographic positions (i.e., relative location from sources and the Great Lakes system) and elevation. We also detect seasonal variations in deposition, showing that total wet atmospheric inorganic N deposition inputs to watersheds (extracted from the four-digit HUC calculations) are highest during the spring (mean = 2.4kg ha-1, stddev = 0.29) and lowest during the winter months (mean = 1.4kg ha-1, stddev = 0.23). Results also suggest that wet NO3- consistently comprises a slightly higher proportion of wet N deposition than wet NH4+ throughout watersheds of New York, ranging from 2.5 to 6.1kg NO3-N ha-1 yr-1 compared to NH4+, which ranges from 2.2 to 4.4kg NH4-N ha-1 yr-1.

We designed a pilot study using 30 samples selected among samples with high and low PCB concentrations to evaluate the feasibility of measuring OH-PCBs in the larger study population. GC-ECD and GC-NCI/MS were used to determine PCBs and OH-PCBs as methyl derivatives, respectively. Maternal serum levels of sub(1) sub(1)PCBs and sub(8)OH-PCB metabolites varied from 0.74 to 7.99 ng/mL wet wt. with a median of 3.05 ng/mL, and from 0.12 to 0.98 ng/mL wet wt. with a median of 0.39 ng/mL, respectively. Average concentrations of sub(8)OH-PCB metabolites in the high PCB group were significantly higher than those in the low PCB group (p<0.05). The levels of OH-PCB metabolites were dependent on PCB levels (r=0.58, p<0.05) but approximately an order of magnitude lower (p<0.05). The average ratio of sub(8)OH-PCBs to sub(1) sub(1)PCBs was 0.14+/-0.08. The primary metabolite was 4-OH-CB187 followed by 4-OH-CB107. Both of these metabolites interfere with the thyroid system in in vitro, animal, and human studies.

The exact characteristics that give certain foods allergenic potential are unclear, but must include both the potential to sensitize (induce IgE) as well as the capacity to avoid induction of oral tolerance (specific inhibition of IgE production). EPA has developed two complementary mouse models; one which distinguishes allergenic from non-allergenic food extracts using oral sensitization with adjuvant (cholera toxin) and another which further distinguishes highly potent allergens following oral administration without adjuvant based on the development (or not) of tolerance. For the foods tested thus far (roasted or raw peanut, Brazil nut, egg white, turkey, and spinach), the ability to sensitize and/or tolerize in these models are consistent with observed allergenicity as well as persistence and severity among allergens. Additionally, in vitro pepsin-resistance analysis of these food extracts suggests an association between sensitization capacity and proteins which are stable to gastric digestion. A subcutaneous exposure model did not distinguish allergenic from non-allergenic foods and does not appear useful for assessing potential allergenicity.

Contaminant analyses included several metals, the hydrophobic organic chemicals (HOCs) polychlorinated biphenyls, several chlorinated pesticides, and polycyclic aromatic hydrocarbons. When compared to estuarine sediments globally, the Ukrainian sediments were found to be moderately contaminated. However, several metals, especially mercury, were often shown to be elevated in the tissues of the Ukrainian organisms in comparison to organisms from other estuarine locations. Sediment quality guidelines indicate some of the estuarine sediments could be sufficiently contaminated to cause adverse toxicological effects. This investigation represents the first extensive study of HOC and metal baseline concentrations and distributions in Ukrainian estuaries and seeks to characterize exposures to aquatic organisms living in these systems.

Global biogenic emissions of isoprene (600 Tg yr super(− 1)) are sufficiently large that the formation of SOA in even small yields results in substantial production of atmospheric particulate matter, likely having implications for air quality and climate. Here we present a review of field measurements, experimental work, and modeling studies aimed at understanding the mechanisms, yield, and atmospheric importance of isoprene-derived SOA. SOA yields depend on a number of factors, including organic aerosol loading (M sub(o)), NO sub(x) level (RO sub(2) chemistry), and, because of the importance of multigenerational chemistry, the degree of oxidation. These dependences are not always included in SOA modules used in atmospheric transport models, and instead most yield parameterizations rely on a single set of chamber experiments (carried out over a limited range of conditions); this may lead to very different estimates of the atmospheric importance of isoprene SOA. New yield parameterizations, based on all available laboratory data (M sub(o)=0-50 kg m super(− 3)), are presented here, so that SOA formation may be computed as a function of M sub(o), NO sub(x) level, and temperature. Current research needs and future research directions are identified.

AN - 67611197; 19708389 AB - Mechanistic and stereoselective based in vitro metabolism assays were utlilized to gain insight into the toxic mode of action of the 1,2,4-triazole fungicide, triadimefon, with black fly (Diptera: Simuliidae) larvae. Based on results from enzyme inhibitor studies, the metabolism of triadimefon in black fly larvae microsomes was found to occur predominantly via an oxidative P450-mediated pathway; triadimenol was formed via the stereoselective reduction of the prochiral carbonyl group of triadimefon. The relatively minor contribution of carbonyl reduction suggests that triadimefon may inhibit ecdysone 20-monooxygenase and disrupt insect molting hormone biosynthesis. 48-h LC50 tests for triadimefon and triadimenol with black fly larvae yielded median values (with 95% confidence intervals) of 6.1 (5.8-6.4) and 22.3 (20.3-24.1) mg/L respectively. The exposure of black fly larvae to sublethal concentrations of triadimefon resulted in increased microsomal P450 activity and affected the microsomal rates of both triadimefon depletion and triadimenol formation. In contrast to trout, black fly larvae produced a higher fraction of the more toxic triadimenol stereoisomers, which may explain in part why triadimefon exhibited a significantly greater toxicity with black fly larvae than trout. These results illustrate that while LC50 tests conducted with commercial triadimenol would presumably expose each organism to the same relative abundance of the four triadimenol stereoisomers, LC50 tests with triadimefon ultimately expose each organism to a unique set of triadimenol stereoisomers depending upon the organism's stereoselective metabolism.

We developed downstream hydraulic geometry relationships for bankfull channel width w as a function of drainage area A, w=a A super(b), (DHG sub(w) sub(A)) for nine aggregate ecoregions comprising the conterminous United States using 1588 sites from the U.S. Environmental Protection Agency's National Wadeable Streams Assessment (WSA), including 1152 sites from a randomized probability survey sample. Sampled stream reaches ranged from 1 to 75 m in bankfull width and 1 to 10,000 km super(2) in drainage area. The DHG sub(w) sub(A) exponent b, which expresses the rate at which bankfull stream width scales with drainage area, fell into three distinct clusters ranging from 0.22 to 0.38. Width increases more rapidly with basin area in the humid Eastern Highlands (encompassing the Northern and Southern Appalachians and the Ozark Mountains) and the Upper Midwest (Great Lakes region) than for the West (both mountainous and xeric areas), the southeastern Coastal Plain, and the Northern Plains (the Dakotas and Montana). Stream width increases least rapidly with basin area in the Temperate Plains (cornbelt) and Southern Plains (Great Prairies) in the heartland. The coefficient of determination (r super(2)) was least in the noncoastal plains (0.36-0.41) and greatest in the Appalachians and Upper Midwest (0.68-0.77). DHG sub(w) sub(A) equations differed between streams with dominantly fine bed material (silt/sand) and those with dominantly coarse bed material (gravel/cobble/boulder) in six of the nine analysis regions. Where DHG sub(w) sub(A) equations varied by sediment size, fine-bedded streams were consistently narrower than coarse-bedded streams. Within the Western Mountains ecoregion, where there were sufficient sites to develop DHG sub(w) sub(A) relationships at a finer spatial scale, a and b ranged from 1.23 to 3.79 and 0.23 to 0.40, respectively, with r super(2)>0.50 for 10 of 13 subregions (range: 0.36 to 0.92). Enhanced DHG equations incorporating additional data for three landscape variables that can be derived from GIS-mean annual precipitation, elevation, and mean reach slope-significantly improved equation fit and predictive value in several regions, most notably the Western Mountains and the Temperate Plains. Channel width was also related to human disturbance. We examined the influence of human disturbance on channel width using several indices of local and basinwide disturbance. Contrary to our expectations, the data suggest that the dominant response of channel width to human disturbance in the United States is a reduction in bankfull width in streams with greater disturbance, particularly in the Western Mountains (where population density, road density, agricultural land use, and local riparian disturbance were all negatively related to channel width) and in the Appalachians and New England (where urban and agricultural land cover and riparian disturbance were all negatively associated with channel width).

AN - 67371344; 19497578 AB - This article describes the development of an analytical method for the determination of fluorotelomer alcohols (FTOHs) in soil. The sensitive and selective determination of the telomer alcohols was performed by extraction with methyl tert-butyl ether (MTBE) and analysis of the extract using gas chromatography with detection and quantification by mass spectrometry operated in the positive chemical ionization mode. The protonated molecular ion, [M+H](+) and a fragment ion (loss of HF+H(2)O) m/z 38 less than the molecular ion were monitored to identify tentatively FTOHs in MTBE extracts of contaminated soils. The FTOHs were confirmed by treatment of the extract with a silylation reagent and observing the disappearance of the FTOH response and the appearance of peaks attributable to the [M+H](+) ions of the trimethylsilyl derivatives. Mass-labeled FTOHs were used as recovery and matrix internal standards. Recovery experiments on soils shown to be free of endogenous FTOHs at instrument detection limits (IDL) of 16 fg/microL for 6:2 FTOH, 10 fg/microL for 8:2 FTOH and 14 fg/microL for 10:2 FTOH yielded a limit of quantitation (LOQ) of 190, 100, and 160 fg/microL for 6:2 FTOH, 8:2 FTOH, and 10:2 FTOH, respectively when 3 g samples of soil were extracted with 1 mL MTBE. The levels of the 6:2 FTOH, 8:2 FTOH, and 10:2 FTOH in five soils contaminated with FTOHs by exposure to the laboratory atmosphere during air drying were determined. In these air-dried soils, concentrations of FTOHs ranged from non-detectable to 3600 fg/microL (0.6 ng/g) of the 6:2 FTOH in the extract of a commercial topsoil.

The exposure assessment modeled stabilization, storage, and consumer preparation such as reheating and hot-holding. The model predicted that assuming a 10- or 100-fold increase from the assumed 1-log (maximal allowable) growth of C. perfringens results in a 1.2- or 1.6-fold increase of C. perfringens-caused illnesses, respectively, at the median of the uncertainty distribution. Improper retail and consumer refrigeration accounted for approximately 90% of the 79,000 C. perfringens illnesses predicted by the model at 1-log growth during stabilization. Improper hot-holding accounted for 8% of predicted illnesses, although model limitations imply that this is an underestimate. Stabilization accounted for less than 1% of illnesses. Efforts to reduce illnesses from C. perfringens in ready-to-eat and partially cooked meat and poultry products should focus on retail and consumer storage and preparation methods.

Five Time Depth Recorders (TDRs) were deployed on turtles returning to the sea following either an unsuccessful or a successful nesting attempt. Because the fringing reef immediately adjacent to Raine Island slopes precipitously to meet the sea floor at depths of 200-300 m (Aus Chart 836), this cay presents an ideal location to investigate the dive behaviour of C. mydas in a deep-water inter-nesting habitat.

AN - 67561459; 19215187 AB - Analyses of observational data can provide insights into relationships between environmental conditions and biological responses across a broader range of natural conditions than experimental studies, potentially complementing insights gained from experiments. However, observational data must be analyzed carefully to minimize the likelihood that confounding variables bias observed relationships. Propensity scores provide a robust approach for controlling for the effects of measured confounding variables when analyzing observational data. Here, we use propensity scores to estimate changes in mean invertebrate taxon richness in streams that have experienced insecticide concentrations that exceed aquatic life use benchmark concentrations. A simple comparison of richness in sites exposed to elevated insecticides with those that were not exposed suggests that exposed sites had on average 6.8 fewer taxa compared to unexposed sites. The presence of potential confounding variables makes it difficult to assert a causal relationship from this simple comparison. After controlling for confounding factors using propensity scores, the difference in richness between exposed and unexposed sites was reduced to 4.1 taxa, a difference that was still statistically significant. Because the propensity score analysis controlled for the effects of a wide variety of possible confounding variables, we infer that the change in richness observed in the propensity score analysis was likely caused by insecticide exposure.

AN - 67412674; 19484287 AB - Water quality was assessed following Hurricane Katrina in the affected waters of Alabama, Mississippi, and Louisiana. Post-landfall water quality was compared to pre-hurricane conditions using indicators assessed by EPA's National Coastal Assessment program and additional indicators of contaminants in water and pathogens. Water quality data collected after Hurricane Katrina suggest that the coastal waters affected by the storm exhibited higher salinity and concentrations of chlorophyll a, dissolved inorganic phosphorus, and total suspended solids following the storm compared to the previous 5-year averages. Higher bottom dissolved oxygen concentrations and light attenuation were also observed. Contaminant concentrations measured in the water column were very low or undetectable, as were the presence of pathogens. Overall water quality did not significantly differ from water quality assessed in the five years preceding the storm. Statistical analyses indicate that use of a probabilistic survey design is appropriate for making pre-storm and post storm comparisons for water quality condition on an areal basis.

AN - 67390344; 19363143 AB - Multigeneration reproduction studies are used to characterize parental and offspring systemic toxicity, as well as reproductive toxicity of pesticides, industrial chemicals and pharmaceuticals. Results from 329 multigeneration studies on 316 chemicals have been digitized into standardized and structured toxicity data within the Toxicity Reference Database (ToxRefDB). An initial assessment of data quality and consistency was performed prior to profiling these environmental chemicals based on reproductive toxicity and associated toxicity endpoints. The pattern of toxicity across 75 effects for all 316 chemicals provided sets of chemicals with similar in vivo toxicity for future predictive modeling. Comparative analysis across the 329 studies identified chemicals with sensitive reproductive effects, based on comparisons to chronic and subchronic toxicity studies, as did the cross-generational comparisons within the multigeneration study. The general pattern of toxicity across all chemicals and the more focused comparative analyses identified 19 parental, offspring and reproductive effects with a high enough incidence to serve as targets for predictive modeling that will eventually serve as a chemical prioritization tool spanning reproductive toxicities. These toxicity endpoints included specific reproductive performance indices, male and female reproductive organ pathologies, offspring viability, growth and maturation, and parental systemic toxicities. Capturing this reproductive toxicity data in ToxRefDB supports ongoing retrospective analyses, test guideline revisions, and computational toxicology research.

AN - 67389176; 19363144 AB - Conazoles are fungicides used to control fungal growth in environmental settings and to treat humans with fungal infections. Mouse hepatotumorigenic conazoles display many of the same hepatic toxicologic responses as the mouse liver carcinogen phenobarbital (PB): constitutive androstane receptor (CAR) activation, hypertrophy, Cyp2b induction, and increased cell proliferation. The goal of this study was to apply transcriptional analyses to hepatic tissues from mice exposed to PB, propiconazole (Pro) or triadimefon (Tri) at tumorigenic exposure levels to reveal similarities and differences in response among these treatments. Mice were administered diets containing PB (850 ppm), Pro (2500 ppm), or Tri (1800 ppm) for 4 and 30 days. Targeted transcriptomic analyses were conducted at the gene level examining differentially expressed genes (DEGs), and subsets of DEGs: cell cycle genes, and transcription factors. Analyses were also conducted on function, pathway and network levels examining Ingenuity Pathway Analysis Tox Lists and Canonical Pathways, and Gene-Go MetaCore dynamic networks and their central hubs. Genes expressed by PB or the two conazoles were also compared with those genes associated with human hepatocellular cancer. The results from these analyses indicated greater differences between PB and the two conazoles than similarities. Significant commonalities between the two conazole treatments were also noted. We posit that the transcriptional profiles of tissues exposed to toxic chemicals inherently contain their mechanisms of toxicity. We conclude that although PB and these 2 conazoles induce mouse liver tumors and exhibit similar toxicological responses, their transcriptional profiles are significantly different and thus their mechanisms of tumorigenic action are likely to differ.

AN - 67387312; 19407338 AB - Electrocardiography (ECG) is one of the standard technologies used to monitor and assess cardiac function, and provide insight into the mechanisms driving myocardial pathology. Increased understanding of the effects of cardiovascular disease on rat ECG may help make ECG assessments in rat toxicology studies routine, thus facilitating continuous measurement of functional decrements associated with cardiotoxicant exposure. These studies seek to test the hypothesis that hypertensive rats are more susceptible to the short-term cardiotoxic effects of doxorubicin (DOX) when compared with normotensive rats with respect to continuously measured ECG endpoints. Male Wistar-Kyoto (WKY) and spontaneously hypertensive (SH) rats surgically implanted with radiotelemeters were treated once a week for three weeks with either vehicle, 1.25 (low), 2.5 (medium), or 5 (high) mg/kg DOX (i.p.). ECG, heart rate (HR), and core body temperature (T(co)) were continuously monitored during the 1-week baseline and throughout the experimental period until rats were sacrificed 24 h after the third injection. DOX prevented normal body weight gain in both strains and significantly decreased diurnal HR and T(co) of high DOX SH rats. In the ECG, SH rats had prolonged baseline PR intervals and QT(c) when compared with WKY rats. All DOX-treated WKY rats subsequently developed PR interval prolongation; however only those treated with high DOX had increased QT(c). DOX caused an increase in ST interval in SH rats, and resulted in ECG morphology changes. The number of arrhythmias due to DOX was increased in both strains. In conclusion, ECG analysis can reveal underlying cardiovascular disease as a risk factor in the heart's response to toxicant-induced injury in the rat; and be a valuable tool to evaluate baseline vulnerability and assess cardiotoxicity.

AN - 67387276; 19363142 AB - Food allergy is a potential risk associated with use of transgenic proteins in crops. Currently, safety assessment involves consideration of the source of the introduced protein, in silico amino acid sequence homology comparisons to known allergens, physicochemical properties, protein abundance in the crop, and, when appropriate, specific immunoglobulin E binding studies. Recently conducted research presented at an International Life Sciences Institute/Health and Environmental Sciences Institute-hosted workshop adds to the scientific foundation for safety assessment of transgenic proteins in five areas: structure/activity, serum screening, animal models, quantitative proteomics, and basic mechanisms. A web-based tool is now available that integrates a database of allergenic proteins with a variety of computational tools which could be used to improve our ability to predict allergenicity based on structural analysis. A comprehensive strategy and model protocols have been developed for conducting meaningful serum screening, an extremely challenging process. Several animal models using oral sensitization with adjuvant and one dermal sensitization model have been developed and appear to distinguish allergenic from non-allergenic food extracts. Data presented using a mouse model suggest that pepsin resistance is indicative of allergenicity. Certain questions remain to be addressed before considering animal model validation. Gel-free mass spectrometry is a viable alternative to more labor-intensive approaches to quantitative proteomics. Proteomic data presented on four nontransgenic varieties of soy suggested that if known allergen expression in genetically modified crops falls within the range of natural variability among commercial varieties, there appears to be no need to test further. Finally, basic research continues to elucidate the etiology of food allergy.

AN - 67355128; 19394595 AB - As a result of the California heat wave in July 2006, county coroners reported that the high temperatures during that period caused approximately 147 deaths. However, heat wave-related deaths are likely to be underreported due to a lack of a clear case definition and the multi-factorial nature of heat-related mortality. Public health policy suggests a need for a careful assessment of mortality following a heat wave. In addition, it is useful to provide a comparison of the mortality impact per degree change during heat waves versus high temperatures observed during non-heat wave periods. Daily data were collected for mortality, weather and ozone in seven California counties impacted by the July 2006 heat wave. The association between apparent temperature and daily mortality was assessed using a Poisson regression model and combined across counties in a meta-analysis. These results were then used to estimate the increases in the number of deaths during the heat wave. Our analysis indicated that during the July heat wave, there was a 9% (95% CI = 1.6, 16.3) increase in daily mortality per 10 degrees Fahrenheit (F) change in apparent temperature for all counties combined. This estimate is almost 3 times larger than the effect estimated for the full warm season of May-September, during the non-heat wave years. Our estimates also determined that actual mortality during the July 2006 heat wave was 2-3 times greater than the coroner estimates. This multi-county analysis provides additional evidence that the attributable risk of mortality following a heat wave may be underestimated by examining only direct heat-related deaths. In addition, we have found that the mortality effect per degrees F is several times higher than that reported during non-heat wave periods.

AN - 67329251; 19409404 AB - The triazole antifungals myclobutanil, propiconazole and triadimefon cause varying degrees of hepatic toxicity and disrupt steroid hormone homeostasis in rodent in vivo models. To identify biological pathways consistently modulated across multiple timepoints and various study designs, gene expression profiling was conducted on rat livers from three separate studies with triazole treatment groups ranging from 6 h after a single oral gavage exposure, to prenatal to adult exposures via feed. To explore conservation of responses across species, gene expression from the rat liver studies were compared to in vitro data from rat and human primary hepatocytes exposed to the triazoles. Toxicogenomic data on triazoles from 33 different treatment groups and 135 samples (microarrays) identified thousands of probe sets and dozens of pathways differentially expressed across time, dose, and species--many of these were common to all three triazoles, or conserved between rodents and humans. Common and conserved pathways included androgen and estrogen metabolism, xenobiotic metabolism signaling through CAR and PXR, and CYP mediated metabolism. Differentially expressed genes included the Phase I xenobiotic, fatty acid, sterol and steroid metabolism genes Cyp2b2 and CYP2B6, Cyp3a1 and CYP3A4, and Cyp4a22 and CYP4A11; Phase II conjugation enzyme genes Ugt1a1 and UGT1A1; and Phase III ABC transporter genes Abcb1 and ABCB1. Gene expression changes caused by all three triazoles in liver and hepatocytes were concentrated in biological pathways regulating lipid, sterol and steroid homeostasis, identifying a potential common mode of action conserved between rodents and humans. Modulation of hepatic sterol and steroid metabolism is a plausible mode of action for changes in serum testosterone and adverse reproductive outcomes observed in rat studies, and may be relevant to human risk assessment.

AN - 67311541; 19306903 AB - In accordance with most toxicity guidelines, developmental studies typically utilize repeated exposures, usually throughout gestation or during organogenesis in particular. However, it is known that developmental toxicity may occur in response to single exposures, especially during specific windows of susceptibility. An overview of the available literature gave sufficient evidence that for many agents, the same endpoints observed in repeated dose, multiple-day studies were also observed in single-day exposures, thus indicating the relevance of developmental toxicity to health assessments of acute exposures. Further, results of benchmark dose modeling of developmental endpoints indicated that for embryo lethality, single-day exposures required a two- to fourfold higher dose than the multiple-day exposures to produce the same level of response. For fused sternebrae, exposures on specific days produced equivalent levels of response at doses that were more similar to those utilized in the repeated exposures. Appreciable differences in biological half-life (and corresponding dose metrics) as well as specific windows of susceptibility may partially explain the observed multiple- vs. single-day exposure dose-response relationships. Our results highlight the need of a more thorough evaluation of outcomes from repeated dose developmental toxicity studies in regards to their importance to chronic and acute risk assessments.

AN - 67243897; 19442844 AB - Goals of reducing fecal contamination in recreational, drinking, shellfishing and other waters and accurately assessing risk from exposure can best be attained if tools to distinguish between sources of pollution are available. The male-specific RNA coliphage (FRNA) genogroups display a trend of source specificity. Reverse transcription-PCR (RT-PCR) can be effectively used for genotyping if specific primer sets are designed to be capable of identifying all members within each genogroup. In this study genogroup-specific primer sets were designed using a minimum of 5 to a maximum of 10 complete phage genome sequences from strains in each genogroup. With these primers and employing a heat-release procedure that eliminated the need for RNA purification an RT-PCR method for genotype identification of FRNA phages was developed. The four genogroup-specific primer sets generated discrete PCR amplicon sizes from a variety of environmental FRNA phage strains. Limits of detection, cross-reactivity and/or non-specific binding to strains from other genogroups were evaluated.

The results of surface geophysical surveys acquired in 1996, 2003, and 2007 document changes in geophysical signatures associated with removing hydrocarbon mass in the contaminated zone. Initial investigations in 1996 showed that relative to background, the contaminated area was characterized by higher bulk electrical conductivity, positive SP anomaly, and attenuated GPR reflections. Repeated surveys in 2003 and 2007 over the contaminated area showed that in 2007, the bulk electrical conductivityhad reverted to near-background conditions, the positive SP anomaly became more negative, and the zone of attenuated GPR reflections showed increased signal strength. Removal of hydrocarbon mass in the vadose zone over the plume by a soil vapor-extraction system installed in 2001 was primarily responsible for the changing geophysical responses. Although chemical data from groundwater showed a 3-m-thick conductive plume in 2007, the plume was not imaged by electrical resistivity. Forward modeling suggests that apparent bulk electrical conductivity of the saturated zone plume has to be three to five times higher than background values to be imaged by electrical resistivity. We suggest that removing hydrocarbon-contaminant-mass reduction by natural or engineered bioremediation can be imaged effectively by temporal geophysical surveys.

Sediments maintained under controlled dissolved oxygen (DO) conditions showed elevated concentrations of Mo when exposed to low DO concentrations. Mo accumulation was linearly related to time of exposure in treatments below 2.8mg O sub(2)/L, with less or no accumulation at higher concentrations. Rates of accumulation were independent of DO concentration below 2.8mg/L. Accumulation occurred at DO concentrations higher than those limiting accumulation in field settings, with rates in the lowest treatments similar to those in sediments of deep basins with restricted circulation and low DO concentrations.

Model testing and validation AN - 21257859; 11715701 AB - We tested a previously described model to assess the wildlife habitat value of New England salt marshes by comparing modeled habitat values and scores with bird abundance and species richness at sixteen salt marshes in Narragansett Bay, Rhode Island USA. As a group, wildlife habitat value assessment scores for the marshes ranged from 307-509, or 31-67% of the maximum attainable score. We recorded 6 species of wading birds (Ardeidae; herons, egrets, and bitterns) at the sites during biweekly survey. Species richness (r super(2)=0.24, F=4.53, p=0.05) and abundance (r super(2)=0.26, F=5.00, p=0.04) of wading birds significantly increased with increasing assessment score. We optimized our assessment model for wading birds by using Akaike information criteria (AIC) to compare a series of models comprised of specific components and categories of our model that best reflect their habitat use. The model incorporating pre-classification, wading bird habitat categories, and natural land surrounding the sites was substantially supported by AIC analysis as the best model. The abundance of wading birds significantly increased with increasing assessment scores generated with the optimized model (r super(2)=0.48, F=12.5, p=0.003), demonstrating that optimizing models can be helpful in improving the accuracy of the assessment for a given species or species assemblage. In addition to validating the assessment model, our results show that in spite of their urban setting our study marshes provide substantial wildlife habitat value. This suggests that even small wetlands in highly urbanized coastal settings can provide important wildlife habitat value if key habitat attributes (e.g., natural buffers, habitat heterogeneity) are present.

Identification and proper interpretation of these relationships are required for accurate assessment of risk to public health. Objectives We review the role of TH in nervous system development and specific outcomes in adults, the impact of xenobiotics on thyroid signaling, the relationship between adverse outcomes of thyroid disruption and upstream causal biomarkers, and the societal implications of perturbations in thyroid signaling by xenobiotic chemicals. Data sources We drew on an extensive body of epidemiologic, toxicologic, and mechanistic studies. Data synthesis THs are critical for normal nervous system development, and decreased maternal TH levels are associated with adverse neuropsychological development in children. In adult humans, increased thyroid-stimulating hormone is associated with increased blood pressure and poorer blood lipid profiles, both risk factors for cardiovascular disease and death. These effects of thyroid suppression are observed even within the anormala range for the population. Environmental chemicals may affect thyroid homeostasis by a number of mechanisms, and multiple chemicals have been identified that interfere with thyroid function by each of the identified mechanisms. Conclusions Individuals are potentially vulnerable to adverse effects as a consequence of exposure to thyroid-disrupting chemicals. Any degree of thyroid disruption that affects TH levels on a population basis should be considered a biomarker of adverse outcomes, which may have important societal outcomes.

The current study utilized a participant-based approach to collect indoor and outdoor air monitoring data from 92 asthmatic and nonasthmatic children (9-13 years old) enrolled in two concurrent health studies in Detroit, Michigan (Mechanistic Indicators of Childhood Asthma and Detroit Children's Health Study) conducted by the US Environmental Protection Agency (EPA). Passive samplers were shipped to participating households and deployed by parents of study participants to collect indoor and outdoor measurements of nitrogen dioxide (NO sub(2)), volatile organic compounds (VOCs), and polycyclic aromatic hydrocarbons (PAHs) including naphthalene. Half of the households deployed VOC and NO sub(2) samplers for 7 days; the other half deployed PAH and NO sub(2) samplers for 2 days and additional PAH samplers for 1 day. Approximately 88% of the households that received air sampling kits completed the air monitoring. Compliance was significantly higher among participants asked to deploy all samplers for 7 days (85%) compared with participants asked to deploy some samplers for 2 days and others for 1 day (56%). The 7-day homes were also more likely to provide usable data (96%) compared with the 1- and 2-day homes (73%). Compliance and providing usable data did not vary between parents of asthmatic versus nonasthmatic study participants and were not reduced among households deploying duplicate samplers. These results suggest that participant-based sampling may be a feasible and cost-effective alternative to traditional exposure assessment approaches that can be applied in future epidemiological and community-based health studies.Journal of Exposure Science and Environmental Epidemiology (2009) 19, 492-501; doi:10.1038/jes.2008.39; published online 9 July 2008 JF - Journal of Exposure Science and Environmental Epidemiology AU - Johnson, Markey AU - Hudgens, Edward AU - Williams, Ronald AU - Andrews, Gina AU - Neas, Lucas AU - Gallagher, Jane AU - Oezkaynak, Haluk AD - [1] aUS Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina, USA [2] bUS Environmental Protection Agency, National Exposure Research Laboratory, Research Triangle Park, North Carolina, USA Y1 - 2009/07// PY - 2009 DA - Jul 2009 SP - 492 EP - 501 PB - Nature Publishing Group, The Macmillan Building London N1 9XW UK VL - 19 IS - 5 SN - 1559-0631, 1559-0631 KW - Pollution Abstracts; Health & Safety Science Abstracts; Toxicology Abstracts KW - Air pollution KW - Air sampling KW - Asthma KW - Children KW - Community involvement KW - Compliance KW - Data processing KW - EPA KW - Economics KW - Epidemiology KW - Households KW - Naphthalene KW - Nitrogen dioxide KW - Pollution effects KW - Pollution monitoring KW - Polycyclic aromatic hydrocarbons KW - Respiratory diseases KW - Samplers KW - Sampling KW - Volatile organic compounds KW - polycyclic aromatic hydrocarbons KW - volatile organic compounds KW - USA, Michigan, Detroit KW - P 0000:AIR POLLUTION KW - H 12000:Epidemiology and Public Health KW - X 24350:Industrial Chemicals UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/20933671?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Atoxicologyabstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.atitle=A+participant-based+approach+to+indoor%2Foutdoor+air+monitoring+in+community+health+studies&rft.au=Johnson%2C+Markey%3BHudgens%2C+Edward%3BWilliams%2C+Ronald%3BAndrews%2C+Gina%3BNeas%2C+Lucas%3BGallagher%2C+Jane%3BOezkaynak%2C+Haluk&rft.aulast=Johnson&rft.aufirst=Markey&rft.date=2009-07-01&rft.volume=19&rft.issue=5&rft.spage=492&rft.isbn=&rft.btitle=&rft.title=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.issn=15590631&rft_id=info:doi/10.1038%2Fjes.2008.39 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2009-10-01 N1 - Last updated - 2012-10-19 N1 - SubjectsTermNotLitGenreText - Nitrogen dioxide; Air pollution; Polycyclic aromatic hydrocarbons; Data processing; Epidemiology; volatile organic compounds; Naphthalene; Asthma; Sampling; Children; Samplers; Pollution monitoring; Community involvement; Compliance; Pollution effects; Respiratory diseases; EPA; Households; Economics; Air sampling; polycyclic aromatic hydrocarbons; Volatile organic compounds; USA, Michigan, Detroit DO - http://dx.doi.org/10.1038/jes.2008.39 ER - TY - JOUR T1 - Multiple regression models for hindcasting and forecasting midsummer hypoxia in the Gulf of Mexico AN - 20877804; 10136874 AB - A new suite of multiple regression models was developed that describes relationships between the area of bottom water hypoxia along the northern Gulf of Mexico and Mississippi-Atchafalaya River nitrate concentration, total phosphorus (TP) concentration, and discharge. Model input variables were derived from two load estimation methods, the adjusted maximum likelihood estimation (AMLE) and the composite (COMP) method, developed by the U.S. Geological Survey. Variability in midsummer hypoxic area was described by models that incorporated May discharge, May nitrate, and February TP concentrations or their spring (discharge and nitrate) and winter (TP) averages. The regression models predicted the observed hypoxic area within c30%, yet model residuals showed an increasing trend with time. An additional model variable, Epoch, which allowed post-1993 observations to have a different intercept than earlier observations, suggested that hypoxic area has been 6450 km super(2) greater per unit discharge and nutrients since 1993. Model forecasts predicted that a dual 45% reduction in nitrate and TP concentration would likely reduce hypoxic area to approximately 5000 km super(2), the coastal goal established by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force. However, the COMP load estimation method, which is more accurate than the AMLE method, resulted in a smaller predicted hypoxia response to any given nutrient reduction than models based on the AMLE method. Monte Carlo simulations predicted that five years after an instantaneous 50% nitrate reduction or dual 45% nitrate and TP reduction it would be possible to resolve a significant reduction in hypoxic area. However, if nutrient reduction targets were achieved gradually (e.g., over 10 years), much more than a decade would be required before a significant downward trend in both nutrient concentrations and hypoxic area could be resolved against the large background of interannual variability. The multiple regression models and statistical approaches applied provide improved capabilities for evaluating dual nutrient management strategies to address Gulf hypoxia and a clearer perspective on the strengths and limitations of approaching the problem using regression models.

Phaeocystis antarctica often occurs in colonial form, but also as solitary cells, and the two forms have distinct ecological roles. A comparison of the growth characteristics of solitary and colonial forms of Phaeocystis sp. is essential to understanding the differential impact each has on biogeochemical and ecological processes, and to allow parameterization of each form in numerical models. We measured the biomass and photosynthetic responses of two size fractions (>20 and <20 km), representing colonies and solitary cells, at locations dominated by P. antarctica to assess the relative photosynthetic potential of the two forms. While the relative contribution of each form to total P. antarctica biomass differed among years, there were no significant differences between maximum photosynthetic rates of colonial and solitary forms within years. Substantial interannual variations in biomass and maximum photosynthetic rates normalized to chlorophyll a (PmB) and initial light-limited rates of photosynthesis (a) were observed among years for the colonial fractions; however, interannual variations in maximum rates of photosynthesis or a of solitary cells were not observed. A laboratory experiment with P. antarctica, together with field data, showed that growth stage of colonies strongly affected the maximum photosynthetic rates. Under nutrient-replete conditions and exponential growth, colonial cells had higher maximum photosynthetic rates than solitary cells, but as growth rate declined and senescence began, the solitary cells' rates became greater. This may be a reason for the high abundance of colonies that is often found in the Ross Sea during austral spring. Our results suggest that photosynthetic rates may influence the composition of the morphotypes of Phaeocystis, but do not appear to be the sole factor in regulating this critical biological variable.

Current practice of estimating cell division (birth) rate alpha by the formula LI(t) = 1 - exp(-2α ; t) suggests that the use of labeling index (LI) as a cell proliferation indicator may incur loss of valuable information inherited in the data that are used to calculate the index. Information about cell death has become increasingly important for understanding a disease processes, and for developing a biologically based dose-response model for environmental health risk assessments. Simple stochastic and deterministic models are proposed for estimating both birth and death rates simultaneously from labeling data.

In this study, the effects of GAC particle size (>2 mm to <0.35 mm) and acid pre- treatment of GAC on Fenton-driven oxidation of methyl-tert-butyl ether (MTBE)-spent GAC were evaluated. Iron (Fe) was amended to the GAC using two methods: (1) untreated - where GAC was amended with a concentrated solution of ferrous sulfate and (2) acid pre-treatment - where GAC was amended with acid followed by sequential applications of a dilute ferrous sulfate solution. Subsequently, MTBE was amended to the GAC, followed by oxidative treatments with H[sub]2O[sub]2. H[sub]2O[sub]2 reaction and MTBE oxidation were inversely correlated with GAC particle size and were attributed to shorter intraparticle diffusion transport distances for both H[sub]2O[sub]2 and MTBE. Image analysis of the GAC cross-sections (i.e., prepared thin sections) revealed that the Fe amended to the GAC extended to the center of the GAC particles. Fe accumulated at higher levels on the periphery of the untreated GAC but Fe dispersal was more uniform in the acid pre-treated GAC. In the acid pre-treated GAC, conditions for MTBE oxidation were favorable and greater levels of MTBE oxidation were measured for all particle size fractions tested. Modeling and critical analysis of H[sub]2O[sub]2 diffusive transport and reaction indicated limited H[sub]2O[sub]2 penetration into large GAC particles which contributed to a decline in MTBE removal. Residual MTBE remaining on the GAC limited the quantity of MTBE that could be re-adsorbed, but no reduction in MTBE sorption capacity resulted from oxidative treatments.

We used multivariate analysis to identify reference strata (reaches for which a single reference expectation was appropriate) on each river. Strata included the Upper Missouri, Lower Missouri, impounded Upper Mississippi, unimpounded Upper Mississippi, and the Ohio River. We created a multimetric stressor gradient for each stratum using a suite of site- and landscape-scale metrics. Site-scale metrics included water chemistry, aquatic and riparian habitat, and human disturbance metrics. Landscape-scale metrics included land use, land cover, and proximity to human disturbance. The gradient was scaled from 0 (least stressed) to 1 (most stressed). Multimetric indices of condition based on fish assemblages for the Lower Missouri and Upper Mississippi River were responsive to stressor gradients based on 18-24 abiotic stressor metrics. Ohio River fish assemblages were responsive to a hand-picked three-metric gradient. We used the y-intercept of quantile regression to predict the fish index value for a stressor gradient value of 0 (the fish index value at a site with the lowest mean stressor gradient score in the reference stratum) which we designated as least-disturbed condition for the fish index for that stratum. We trisected the difference between predicted least-disturbed condition (ceiling value) and a floor value set at the 5th percentile of the sample to create thresholds for three condition classes: least-disturbed, intermediate, and most-disturbed. Based on the derived condition class thresholds for the fish index, 10% (by length) of the Lower Missouri was in least-disturbed condition, compared to 14% of the Ohio River and 19% of the impounded Upper Mississippi River. The index of condition exhibited longitudinal variation that was associated with the location of major urban areas along each river. We conclude that empirical modeling based on an abiotic stressor gradient can provide an alternative approach for deriving internal reference expectations for great rivers with few, if any, minimally disturbed sites.

AN - 20259122; 8880777 AB - Recent court cases have questioned whether all headwater streams, particularly those that are not perennial, fall within the protective boundaries of the Clean Water Act. Rapid field-based indicators of hydrologic permanence are critically needed for jurisdictional determinations. The study objective was to determine whether characteristics of bryophyte assemblages in forested headwater streams can be useful indicators of hydrologic permanence. We sampled bryophytes from the channel thalweg at 113 sites across 10 forests in the U.S. which varied in hydrologic permanence. Hydrologic permanence was based on hydrologic status during spring (wet season) and late summer (dry season) visits. Perennial sites had flow (surface or visibly interstitial) during both spring and summer visits. Intermittent sites flowed during spring but were either dry or had surface water limited to isolated pools in summer. Ephemeral sites did not have flow during either visit. The species composition significantly differed between ephemeral and perennial stream reaches. The species composition of intermittent streams overlapped with both ephemeral and perennial streams. Three species and six families were identified as indicators of particular permanence classes. Liverworts occurred more frequently at perennial than at intermittent or ephemeral sites. Bryophytes with cushion and turf growth forms were common to ephemeral sites, whereas mat and weft forms were more common to perennial sites. Acrocarpous mosses were more frequent at ephemeral than at perennial sites. The frequencies of bryophyte-moisture associations (derived from the literature) across the three permanence categories were significantly different. Species associated with dry habitats were more frequently encountered at ephemeral than perennial sites, whereas species associated with wet habitats were more frequent at perennial than ephemeral sites. Species richness varied among forests and permanence classes. Ephemeral sites tended to have higher species richness than perennial sites; however, this pattern did not hold for all forests. Bryophytes should be included among the tools for jurisdictional determinations, much like vascular plants are used to help delineate wetlands. Growth forms and higher level taxonomy of bryophytes (i.e., phyla) can be particularly useful for making jurisdictional determinations because of their ability to discriminate ephemeral from intermittent and perennial reaches and they are measures that can be rapidly trained and routinely used by agencies making such determinations.

More information is needed on interactive CO sub(2) and O sub(3) effects on roots, particularly fine-root life span, a critical demographic parameter and determinant of soil C and N pools and cycling rates. We conducted a study in which ponderosa pine (Pinus ponderosa) seedlings were exposed to two levels of CO sub(2) and O sub(3) in sun-lit controlled-environment mesocosms for 3years. Minirhizotrons were used to monitor individual fine roots in three soil horizons every 28days. Proportional hazards regression was used to analyze effects of CO sub(2), O sub(3), diameter, depth, and season of root initiation on fine-root survivorship. More fine roots were produced in the elevated CO sub(2) treatment than in ambient CO sub(2). Elevated CO sub(2), increasing root diameter, and increasing root depth all significantly increased fine-root survivorship and median life span. Life span was slightly, but not significantly, lower in elevated O sub(3), and increased O sub(3) did not reduce the effect of elevated CO sub(2). Median life spans varied from 140 to 448days depending on the season of root initiation. These results indicate the potential for elevated CO sub(2) to increase the number of fine roots and their residence time in the soil, which is also affected by root diameter, root depth, and phenology.

In this review, we focus on environmental cleanup and provide a background and overview of current practice; research findings; societal issues; potential environment, health, and safety implications; and future directions for nanoremediation. We do not present an exhaustive review of chemistry/engineering methods of the technology but rather an introduction and summary of the applications of nanotechnology in remediation. We also discuss nanoscale zerovalent iron in detail. We searched the Web of Science for research studies and accessed recent publicly available reports from the U.S. Environmental Protection Agency and other agencies and organizations that addressed the applications and implications associated with nanoremediation techniques. We also conducted personal interviews with practitioners about specific site remediations. We aggregated information from 45 sites, a representative portion of the total projects under way, to show nanomaterials used, types of pollutants addressed, and organizations responsible for each site. Nanoremediation has the potential not only to reduce the overall costs of cleaning up large-scale contaminated sites but also to reduce cleanup time, eliminate the need for treatment and disposal of contaminated soil, and reduce some contaminant concentrations to near zero-all in situ. Proper evaluation of nanoremediation, particularly full-scale ecosystem-wide studies, needs to be conducted to prevent any potential adverse environmental impacts.

AN - 67487471; 19603637 AB - The U.S. Department of Housing and Urban Development in collaboration with the United States Environmental Protection Agency conducted a survey measuring lead, allergens, and insecticides in a randomly selected nationally representative sample of residential homes. Multistage sampling with clustering was used to select the 1131 homes of which a subset of 500 randomly selected homes included the collection of hard surface floor wipes. Samples were collected by trained field technicians between June 2005 and March 2006 using isopropanol wetted wipes. Samples were analyzed for a suite of 24 compounds which included insecticides in the organochlorine, organophosphate, pyrethroid and phenylpyrazole classes, and the insecticide synergist piperonyl butoxide. The most commonly detected were permethrin (89%), chlorpyrifos (78%), chlordane (64%), piperonyl butoxide (52%), cypermethrin (46%), and fipronil (40%). Mean and geometric mean (GM) concentrations varied widely among compounds, but were highest for trans-permethrin (mean 2.22 ng/cm2 and GM 0.14 ng/ cm2) and cypermethrin (mean 2.9 ng/cm2 and GM 0.03 ng/ cm2). Results show that most floors in occupied homes in the U.S. have measurable levels of insecticides that may serve as sources of exposure to occupants.

AN - 67140128; 19081184 AB - Herein, we show an important transformation of Pb(II) to Pb(IV) in chlorinated water under laboratory conditions. The study results will give an insight toward understanding how corrosion by-products on lead materials found in drinking water distribution systems develop and breakdown with time. The experiments were conducted to elucidate the morphology of lead (IV) oxide mineral transformation from hydrocerussite and its relationship to color change over a period of time. Scanning electron microscopy and transmission electron microscopy were used to describe the surface morphology, shape and size of lead solids. X-ray diffraction (XRD) analysis was performed to determine the mineral structure of lead solids. Solids analysis results were compared over a 14-day period of time to define changes in the crystal structure and morphology of lead solids. XRD analysis results of freshly synthesized lead solids showed that hydrocerussite, [Pb(3)(CO(3))(2)(OH)(2)], was the only lead mineral present. After 14 days, a mixture of cerussite (PbCO(3)) and alpha-PbO(2) and beta-PbO(2) was present. Lead precipitates, i.e. hydrocerussite changed color from white to reddish brown confirming a transformation of the lead phase with time. This was correlated to a change in morphology from flower shaped crystals to hexagonal bars and submicron particles.

AN - 67139998; 19059706 AB - Sorption of polychlorinated biphenyls (PCBs) to sediment is a key process in determining their mobility, bioavailability, and chemical decomposition in aquatic environments. In order to examine the validity of currently used interpretation approaches for PCBs sorption, comparative results on 2-chlorobiphenyl sorption to carbonaceous components in sediments (activated carbon, carbon black, coal, soot, graphite, flyash, wood) were macroscopically correlated with the structural, morphological, crystallographic, and compositional properties of the carbonaceous components. Since the Freundlich sorption constant, K(F) (Lkg(-1)) spanned several orders of magnitude, ranging from logK(F) of 6.13-5.27 for activated carbon, 5.04 for carbon black, 3.83 for coal to 3.08 for wood, organic carbon partitioning approach should be more specifically categorized, considering the various forms, nature and origins of organic carbon in sediment. Sorption rate constants and fraction parameters, which were numerically defined from empirical kinetic model with fast and slow sorption fractions, were closely related to the physicochemical properties of the carbonaceous components. Sorption interpretation approaches with a specific property and viewpoint, such as organic carbon partitioning, soot carbon distribution, or surface area correlation, did not properly explain the overall results on sorption capacity, fast and slow sorption kinetics, and partitioning coefficient. It is also important to emphasize the heterogeneous nature of sediment and the difficulties of encompassing the partitioning among its carbonaceous components.

(eelgrass) following experimental shoot removal AN - 20603120; 9311670 AB - The recovery of eelgrass (Zosteramarina) from physical disturbances is understudied and no attention has been given to the likely differences in damage recovery rates between the continuous lower intertidal perennial meadows and higher intertidal eelgrass patches. In the present study, 4 m super(2) plots were treated by removing all eelgrass shoots and followed over a 3 year period until they attained control (untreated) plot shoot densities. The number and types of shoots (vegetative, reproductive, and seedling) were counted semi-monthly with comparisons made between experimental and control plots. In the second year of the study additional plots were denuded and sown with Z.marina seeds to evaluate the importance of seedlings in the recovery process. Our results suggest that recovery in both low and high intertidal plots was due exclusively to rhizome growth from adjacent perennial eelgrass. This recovery began immediately within the permanent eelgrass meadow and was complete within 24 months. Denuded transition zone patches took almost twice as long to recover to control densities. Natural seedling production appeared to play no part in recovery. When larger numbers of seeds were planted into denuded plots in the winter, only a small portion of them produced seedlings in the spring and none appear to survive through the summer. These experimental eelgrass recovery rates were similar to recovery rates determined from aerial photographs of an eelgrass meadow damaged by a boat grounding near the study site. We suggest that transition zone perennial patches are more vulnerable to natural and anthropogenic disturbance events than lower intertidal eelgrass meadows.

13267759 AB - For up to 1 billion people worldwide, insufficient dietary intake of selenium (Se) is a serious health constraint. Cereals are the dominant Se source for those on low protein diets, as typified by the global malnourished population. With crop Se content constrained largely by underlying geology, regional soil Se variations are often mirrored by their locally grown staples. Despite this, the Se concentrations of much of the world's rice, the mainstay of so many, is poorly characterized, for both total Se content and Se speciation. In this study, 1092 samples of market sourced polished rice were obtained. The sampled rice encompassed dominant rice producing and exporting countries. Rice from the U.S. and India were found to be the most enriched, while mean average levels were lowest in Egyptian rice: 32-fold less than their North American equivalents. By weighting country averages by contribution to either global production or export, modeled baseline values for both were produced. Based on a daily rice consumption of 300 g day-1, around 75% of the grains from the production and export pools would fail to provide 70% of daily recommended Se intakes. Furthermore, Se localization and speciation characterization using X-ray fluorescence (*m-XRF) and X-ray absorption near edge structure (*m-XANES) techniques were investigated in a Se-rich sample. The results revealed that the large majority of Se in the endosperm was present in organic forms.

While pristine anatase TiO2 nanoparticles (ANTNPs) were completely immobile, the presence of CMC significantly enhanced their mobility. The magnitude of the surface charge exhibited by the CMC-coated anatase TiO2 nanoparticles (CMC-ANTNPs) significantly exceeded that of the uncoated ANTNPs, thereby leading to a negative surface charge over the pH range investigated (2-10). The mobility of CMC-ANTNPs was retarded by the presence of amorphous Fe and Al hydroxide, Na+ (30 mM), and Ca2+ (30 mM). Removal of CMC-ANTNPs was more significant in the presence of either Ca2+ or Fe-hydroxide. More retardation and incomplete breakthrough of the CMC-ANTNPs was observed in the mineral-coated sands. This is possibly due to an order of magnitude increase in the surface area of mineral-coated sands compared with the clean quartz sand grains and the potential for chelation between CMC bound to ANTNPs and Fe and Al hydroxides. Chemical-colloidal interactions such as chemicomplexation and ligand exchange were the most important factor controlling mobility of CMC-ANTNPs in mineral-coated sands.

Here, a consolidated description of histology evaluation practices, core diagnostic criteria and severity grading schemes for the AMA, an atlas of the normal architecture of amphibian thyroid glands over the course of metamorphosis, and the core diagnostic criteria with examples of severity grades is provided. Core diagnostic criteria include thyroid gland hypertrophy/atrophy, follicular cell hypertrophy, and follicular cell hyperplasia. The severity grading scheme is semiquantitative and employs a four-grade approach describing ranges of variation within assigned ordinal classes: not remarkable, mild, moderate, and severe. The purpose of this severity grading approach is to provide an efficient, semi-objective tool for comparing changes (compound-related effects) among animals, treatment groups, and studies. Proposed descriptions of lesions for scoring the four core criteria are also given.

Particularly when a finite number of quantitative metrics is used to characterize the system, the values of the metrics among the states can exhibit increasing and decreasing trends at the same time, creating difficulty in clearly preferring one to the other. Sometimes, unequal weighting factors are ascribed to metrics to show the relative importance of the metrics, further complicating the comparison. It has been deemed desirable to consolidate all the usable metrics into one aggregate metric to make this comparison easier. Such an attempt is provided here by expressing the aggregate metric as the geometric mean of the ratios of the individual metrics for pair-wise comparisons. This computation was applied to previously reported evaluations of processes with a finite number of metrics.

AN - 67512754; 19455576 AB - In developmental and reproductive toxicity studies, drinking water is a common means of delivering the test agent. Reduced consumption of toxicant-containing water raises questions about indirect effects of reduced maternal fluid consumption resulting from unpalatability, versus direct effects of the test compound. Issues to consider include: objective assessment of dehydration and thirst, the relative contributions of innate and learned behaviors to drinking behavior and flavor preference, and the objective assessment of physiologic stress. Not only do lab animals under ad lib conditions consume more water than the minimum required to maintain fluid balance, animals faced with water restriction have substantial physiologic capacity for protection of metabolic processes. Measures of blood biochemistry can provide quantifiable, objective indications of fluid balance, but changes in these parameters could result from other causes such as effects of a test toxicant. Consummatory behaviors in response to perceived need are highly influenced by learning. Hence, the drinking behavior, water intake, and flavor acceptance/preference of animals used in toxicology experiments could be subject to learning experiences with the test compound. Physiological symptoms of stress produced by water deprivation may be distinguishable from the symptoms associated with other generalized stressors, such as food deprivation, but doing so may be beyond the scope of most developmental or reproductive toxicity studies. Use of concurrent controls, paired to test groups for water consumption, could help distinguish between the direct effects of a test toxicant as opposed to effects of reduced water consumption alone. 2009 Wiley-Liss, Inc.

AN - 67469717; 19590675 AB - Traditional hazards such as poor sanitation currently account for most of Africa's environmentally related disease burden. However, with rapid development absent appropriate safeguards for environment and health, modern environmental health hazards (MEHHs) may emerge as critical contributors to the continent's disease burden. We review recent evidence of human exposure to and health effects from MEHHs, and their occurrence in environmental media and consumer products. Our purpose is to highlight the growing significance of these hazards as African countries experience urbanization, industrial growth, and development. We reviewed published epidemiologic, exposure, and environmental studies of chemical agents such as heavy metals and pesticides. The body of evidence demonstrates ongoing environmental releases of MEHHs and human exposures sometimes at toxicologically relevant levels. Several sources of MEHHs in environmental media have been identified, including natural resource mining and processing and automobile exhaust. Biomonitoring studies provided direct evidence of human exposure to metals such as mercury and lead and pesticides such as p,p'-dichlorodiphenyltrichloroethane (DDT) and organophosphates. Land and water resource pollution and industrial air toxics are areas of significant data gaps, notwithstanding the presence of several emitting sources. Unmitigated MEHH releases and human exposure have implications for Africa's disease burden. For Africans encumbered by conditions such as malnutrition that impair resilience to toxicologic challenges, the burden may be higher. A shift in public health policy toward accommodating the emerging diversity in Africa's environmental health issues is necessary to successfully alleviate the burden of avoidable ill health and premature death for all its communities now and in the future.

AN - 67440915; 19569342 AB - Reactive activated carbon (RAC) impregnated with palladized iron has been developed to effectively treat polychlorinated biphenyls (PCBs) in the environment by coupling adsorption and dechlorination of PCBs. In this study, we addressed the dechlorination reactivity and capacity of RAC toward aqueous 2-chlorobiphenyl (2-ClBP), and its aging and longevity under various oxidizing environments. RAC containing 14.4% Fe and 0.68% Pd used in this study could adsorb 122.6 mg 2-ClBP/g RAC, and dechlorinate 56.5 mg 2-ClBP/g RAC which corresponds to 12% (yield) of its estimated dechlorination capacity. Due to Fe0 oxidation to form oxide passivating layers, Fe2O3/Fe3O4 (oxide-water interface) and FeOOH/FeO (oxide-metal interface), RAC reactivity decreased progressively over aging under N2 < H2O + N2 < H2O + 02 conditions. Considering nanoscale Fe/Pd corrosion chemistry, the decline was quite slow at only 5.6%, 19.5%, and 32.5% over one year, respectively. Dissolved oxygen played a crucial role in enhancing 2-ClBP adsorption but inhibiting its dechlorination. The reactivity change could be explained with the properties of the aged RAC including surface area, Fe0 content and Fe species. During the aging and oxidation, the RAC showed limited dissolution of Fe and Pd. Finally, implementation issues regarding application of RAC system to contaminated sites are discussed.

AN - 67280863; 19332651 AB - A publicly available toxicogenomics capability for supporting predictive toxicology and meta-analysis depends on availability of gene expression data for chemical treatment scenarios, the ability to locate and aggregate such information by chemical, and broad data coverage within chemical, genomics, and toxicological information domains. This capability also depends on common genomics standards, protocol description, and functional linkages of diverse public Internet data resources. We present a survey of public genomics resources from these vantage points and conclude that, despite progress in many areas, the current state of the majority of public microarray databases is inadequate for supporting these objectives, particularly with regard to chemical indexing. To begin to address these inadequacies, we focus chemical annotation efforts on experimental content contained in the two primary public genomic resources: ArrayExpress and Gene Expression Omnibus. Automated scripts and extensive manual review were employed to transform free-text experiment descriptions into a standardized, chemically indexed inventory of experiments in both resources. These files, which include top-level summary annotations, allow for identification of current chemical-associated experimental content, as well as chemical-exposure-related (or "Treatment") content of greatest potential value to toxicogenomics investigation. With these chemical-index files, it is possible for the first time to assess the breadth and overlap of chemical study space represented in these databases, and to begin to assess the sufficiency of data with shared protocols for chemical similarity inferences. Chemical indexing of public genomics databases is a first important step toward integrating chemical, toxicological and genomics data into predictive toxicology.

AN - 67265466; 19339666 AB - Meta- and reanalyses of the available data for the neurobehavioral effects of acute inhalation exposure to toluene were reported by Benignus et al. The present study was designed to test the generality of the toluene results in as many other solvents as possible by further meta- and reanalyses. Sufficient data for meta-analyses were found for only four solvents; toluene, trichloroethylene, perchloroethylene, and 1,1,1-trichloroethane. The results for these solvents showed that rats were less affected by each of the solvents when they were tested in highly motivating situations, for example, rewarded for rapid or correct responding or escape from electrical shock, compared with less motivating circumstances. The four solvents did not differ significantly in potency on any outcome measure when dose was expressed as molar brain concentration. When tested in tasks with low-motivational contingencies, the dose-effect curves of humans (reaction times) and rats (electrophysiological responses to visual stimuli) were not significantly different. However, on an exploratory follow-up analysis, humans were less sensitive than rats. No human data were found to test whether species differed under strong motivation. Dose-equivalence curves were derived for extrapolating to human effects from rat data.

AN - 67260864; 19234105 AB - Exposure to ambient ultrafine particles has been associated with cardiopulmonary toxicity and mortality. Adverse effects specifically linked to ultrafine particles include loss of sympathovagal balance and altered hemostasis. To characterize the effects of acute exposure to ambient ultrafine particles in young healthy humans. Nineteen healthy nonsmoking male and female subjects between the ages of 18 and 35 were exposed to filtered air or to an atmosphere in which captured ultrafine (<0.16 microm) particles were concentrated by a factor of up to 20-fold over ambient levels with the use of particle concentrators fitted with size-selective outlets (ultrafine concentrated ambient particles [UFCAPs]). Subjects underwent bronchoalveolar lavage 18 hours after each exposure. Cardiovascular endpoints measured included pulmonary function, clinical chemistry, and hematological parameters, as well as heart rate variability and repolarization indices. Exposure to UFCAPs was statistically associated with an increase in frequency domain markers of heart rate variability, specifically indicative of elevated vagal input to the heart. Consistent with this finding were increases in the variance associated with the duration of the QT interval. In addition, UFCAP exposure resulted in a significant increase in blood levels of the fibrin degradation product D-dimer as well as a modest elevation in the inflammatory chemokine IL-8 recovered in the lavage fluid. These findings show mild inflammatory and prothrombic responses and are suggestive of alterations in cardiac repolarization induced by UFCAP inhalation.

To use conventional water quality sensors for the purpose, we have explored a real-time event adaptive detection, identification and warning (READiw) methodology and examined it using pilot-scale pipe flow experiments of 11 chemical and biological contaminants each at three concentration levels. The tested contaminants include pesticide and herbicides (aldicarb, glyphosate and dicamba), alkaloids (nicotine and colchicine), E. coli in terrific broth, biological growth media (nutrient broth, terrific broth, tryptic soy broth), and inorganic chemical compounds (mercuric chloride and potassium ferricyanide). First, through adaptive transformation of the sensor outputs, contaminant signals were enhanced and background noise was reduced in time-series plots leading to detection and identification of all simulated contamination events. The improved sensor detection threshold was 0.1% of the background for pH and oxidation-reduction potential (ORP), 0.9% for free chlorine, 1.6% for total chlorine, and 0.9% for chloride. Second, the relative changes calculated from adaptively transformed residual chlorine measurements were quantitatively related to contaminant-chlorine reactivity in drinking water. We have shown that based on these kinetic and chemical differences, the tested contaminants were distinguishable in forensic discrimination diagrams made of adaptively transformed sensor measurements.

The ecological and economic consequences of this development strategy will affect over 100million people and change the organization of the Chinese landscape. In this study, we examined the agricultural development of Shunde, a small city in Guangdong Province, over the period 1978 until 2000. Our analysis of the ecological and economic dynamics of the agricultural system revealed the dominant role of labor in the intensification of agricultural production, even though the use of fuels, fertilizers and machines also increased during this time. The Shunde agricultural system was examined from both biophysical or donor-based and human utility or receiver-based perspectives, using emergy and economic methods, respectively. After 22years of urbanization, the Shunde agricultural system was still able to fill 96% of the local demand for agricultural products using only 6% of its total yield compared to using 14% of the total yield in 1978. Aquaculture developed quickly during the study period as grain production decreased. In 2000, the production of fish, pork, and vegetables accounted for 92% of the total emergy output of the system; however, the emergy buying power of the money received in exchange was lower than the emergy contained in the products exported. The excess emergy exported is the basis for a high quality diet delivered to city dwellers at a relatively low price. In the 1980s, the productivity of both land and labor increased; but after 1992 the productivity of labor decreased, causing the efficiency of the whole agricultural system to decrease. We recommend that processing plants be established for the main agricultural products of Shunde to decrease the emergy loss in trading and to increase employment. The effect of including monetized ecosystem services in the balance between the emergy delivered to the markets in agricultural products and the emergy buying power of the money received was to decrease the emergy gained by the Shunde agricultural system.

Recently, there has been growing interest in utilizing HIA methods at local scales, in the context of Environmental Public Health Tracking and in other settings. This paper investigates the data and analytical challenges to estimating the incidence of health effects associated with changes in air pollution concentrations at the local scale, focusing on ozone and fine particulate matter. Although it could be argued that the local-scale HIA is simply a more geographically discrete version of the national-scale assessment and, therefore, has similar challenges, in practice, many key inputs in national-scale assessments are assumed to be spatially uniform or vary only at coarse geographic resolution. For a national-scale assessment, this assumption may not contribute appreciable bias, but the bias could be significant for any individual location. Thus, local-scale assessments require more geographically resolved air quality data, concentration-response (C-R) functions, and baseline incidence rates than are often used. However, comprehensive local data may not be available, may be incomplete, or may be time-intensive and resource-intensive to develop, especially for C-R functions for which small-scale epidemiological studies will often be underpowered. Given this context, this paper considers how best to develop credible local-scale HIAs, identifying factors that contribute to variability across geographic areas, study designs, and time periods. This paper also describes which key sources of analytical uncertainty change as the scope shifts from the national to the local scale. These challenges notwithstanding, the paper concludes that a well-designed local-scale HIA, following key principles and recommendations, can be both informative and defensible.

Mines often occur in mountain environments with fractured bedrock aquifers that serve as pathways for metals transport to streams. This study evaluates impacts from current and potential future groundwater metal (Cd, Cu, and Zn) loads from fractures underlying the Gilt Edge Mine, South Dakota, on concentrations in Strawberry Creek using existing flow and water quality data and simple mixing/dilution mass balance models. Results showed that metal loads from bedrock fractures to the creek currently contribute <1% of total loads. Even if background water quality is achieved upstream in Strawberry Creek, fracture metal loads would be <5%. Fracture loads could increase substantially and cause stream water quality standards exceedances once groundwater with elevated metals concentrations in the aquifer matrix migrates to the fractures and discharges to the stream. Potential future metal loads from an upstream fracture would contribute a small proportion of the total load relative to current loads in the stream. Cd has the highest stream concentrations relative to standards. Even if all stream water was treated to remove 90% of the Cd, the standard would still not be achieved. At a fracture farther downstream, the Cd standard can only be met if the upstream water is treated achieving a 90% reduction in Cd concentrations and the median stream flow is maintained.

This paper reports that ozone-enhance V sub(2)O sub(5)/TiO sub(2) catalyzed oxidation is a stable and effective process to remove methanol and TRS compounds in the presence of moisture that has composition similar to the effluent stream coming out of a pulp mill blow tank. The effect of moisture on the oxidation of CH sub(3)OH, MT and DMS was studied using V sub(2)O sub(5)/TiO sub(2) as a catalyst at different feed compositions (C sub(methanol): 1000 and 7500 ppm; C sub(DMS): 250 and 1000 ppm; and C sub(MT): 250 and 1000 ppm) and gas hourly space velocities (37,000-150,000 h super(-1)) at 250 [degree]C and O sub(3)-to-substrate mole ratio of 2.1. Conversions of methanol and TRS compounds were high and the main products were CO sub(2), CO and SO sub(2) with small amounts of partial oxidation products. Increasing the relative humidity of the gas stream from zero to 18,000 ppm reduced the conversion of methanol, whereas the conversion of TRS compounds was not affected, although the selectivity for partial oxidation products of TRS compounds decreased. High moisture levels have inhibition effect on the reactions because of competitive adsorption of methanol and water on to the same sites. The increase in the complete oxidation of TRS products could be due to forming hydroxyl ion radicals in presence of ozone and water molecules. Possible reaction mechanisms have been proposed for the complete oxidation of methanol and TRS compounds with ozone based on the product distribution.

Physiologically-based pharmacokinetic (PBPK) modeling can assist in understanding resulting internal doses of CCl sub(4) after exposure, but the pharmacokinetic parameters describing the metabolism of CCl sub(4) are not well characterized. The goal of this study was to provide insights into how to more accurately estimate these values in rats using PBPK modeling and data from previous studies. Three different PBPK models were constructed to describe CCl sub(4) exposure in rats via inhalation, oral ingestion, and venous injection. Each of these models was compared to data, and sensitivity analysis was performed for each model to determine whether the available data could be used to accurately determine the metabolic parameters of interest. These parameter sensitivities were so low that optimization to the available data yielded physiologically unrealistic results. Model sensitivities were analyzed for different doses and routes of exposure in order to find experimental conditions that would allow for greater identifiability of the metabolic parameters. Data were simulated from these models at optimal conditions with varying levels of noise from a normal distribution. Optimizations were then performed to confirm that the original values could be obtained. The experiments developed are left as suggestions for investigators who wish to further pursue estimating these metabolic parameters.

To investigate this effect, we developed a multiscale modeling framework for blue crab (Callinectes sapidus) in the northern Gulf of Mexico. Areal coverage of shoreline land cover and SAV for Mobile Bay, Alabama, were combined with information from small-scale biological studies and long-term, large-scale commercial fishery data to model the potential effects of marginal habitat losses on the blue crab fishery. We applied stochastic variation in annual recruitment to the fishery to estimate probabilities for sustainable harvests under scenarios of habitat loss. The simulations suggested that, accumulated over large areas, relatively small local losses of estuarine marsh edge and SAV habitats could have long-term negative effects on the sustainability of the fishery. Spatially extensive models are required to investigate the cumulative ecological effects of many local environmental changes. The requisite scaling adds uncertainty and reduces precision, but if model parameters are accurate at each scale, accurate predictions of long-term outcomes and probabilities are possible.

Over specific spatial-temporal scale ranges, complex systems can configure in a variety of regimes, each defined by a characteristic set of self-organized structures and processes. A system may remain within a regime or dramatically shift to another regime. Understanding the drivers of regime shifts has provided critical insight into system structure and resilience. Although analyses of regime shifts have tended to focus on the system level, new evidence suggests that the same system behaviors operate within scales. In essence, complex systems exhibit multiple dynamic regimes nested within the larger system, each of which operates at a particular scale. Discrete size classes observed in variables in complex systems are evidence of these multiple regimes within complex systems, and the discontinuities between size classes indicate changes in scale.

The mean of model-predicted site-specific values for sites within each region was found generally to overestimate the corresponding model-predicted regional wet ion deposition. On an annual basis across four regions in the eastern US, these overestimates of regional wet ion deposition were typically between 5 and 25% and may be more exaggerated for individual seasons. Corresponding overestimates of regional precipitation were typically <5%, but may be more exaggerated for individual seasons. Period-to-period relative changes determined from the mean of site-based model-predicted wet deposition for the current regional ensembles of sites generally estimated larger beneficial effects of pollutant emissions reductions in comparison to changes based on model-predicted regional wet deposition. On an annual basis site-based relative changes were generally biased low compared to regional relative changes: differences were typically <7%, but they may also be more exaggerated for individual seasons. Spatial heterogeneities of the wet ion deposition fields with respect to the sparse monitoring site locations prevented the monitoring sites considered in the current study from providing regionally representative results. Monitoring site locations considered in the current study over-represent the geographical areas subject to both high emissions and high wet ion deposition and under-represent the geographical areas subject to low emissions and low wet deposition. Since the current case studies consider only those eastern US site locations that have supported concurrent wet and dry deposition monitoring, similar errors may be expected for dry and total deposition using results from the same monitoring site locations. Current case study results illustrate the approximate range of potential errors and suggest caution when inferring regional acid deposition from a network of sparse monitoring sites.

The contributions are computed using the following steps: 1) Evaluate dispersion model estimates with 10-min averaged NO data measured at 7 m and 17 m from the edge of the road during a field study conducted in August, 2006; this step determines the uncertainty in model estimates. 2) Use dispersion model estimates and their uncertainties, determined in step 1, to construct pseudo-observations. 3) Fit pseudo-observations to actual observations of VOC concentrations measured during five periods of the field study. This provides estimates of the contributions of traffic emissions to the VOC concentrations at the receptors located from 10 m to 100 m from the road. In addition, it provides estimates of emission factors and background concentrations of the VOCs, which are supported by independent estimates from motor vehicle emissions models and regional air quality measurements. The results presented in the paper demonstrate the suitability of the formulation in AERMOD for estimating concentrations associated with mobile source emissions near roadways. This paper also presents an evaluation of the key emissions and dispersion modeling inputs necessary for conducting assessments of local-scale impacts from traffic emissions.

For the organic farmer, they offer very attractive and environmentally-benign pest control options in IPM strategies. The U.S. pesticide registration process is rigorous and complex; it involves comprehensive review and assessment of science and economic data or information to support federal pre-market approval and periodic evaluations of labeled uses for manufacturers, distributors and users in the agricultural, industrial, structural, municipal, commercial, residential and recreational sectors. The Office of Pesticide Programs in the U.S. Environmental Protection Agency uses the standard tiered risk assessment paradigm of analyzing hazards and exposures to assess pesticidal risks to human health and to the environment. Within this tiered structure, potential risks are determined first from estimates of acute hazard and limited exposures under worst-case scenarios. Studies at the lower tiers are essentially screening tests--simple in design, but broad in scope. Higher tier testing may encompass field testing and sub-chronic or repeated dose exposures. A risk assessment is developed from a synthesis of results from tiered testing, intended uses and the open literature to fulfill data requirements addressing the primary disciplines of product characterization (i.e., microbial product analysis or biochemical product chemistry) and manufacturing, mammalian health and ecological or environmental effects. The presentation will provide an overview of a risk assessment and the registration process for biopesticides, based on over 30 years of regulatory experience.

We used tree ring growth patterns and stable isotopes to understand long-term physiological responses to fertilization using a controlled fertilization experiment begun in 1964 in Washington State (USA), in which three levels of nitrogen fertilizer were applied: 157, 314, and 471 kg/ha. Basal area increment (BAI) increased more than fourfold in the highest treatment to twofold in the lowest, and a significant increase in BAI was observed for 20 years. Latewood super(13)C sharply decreased by 1.4ppt after fertilization and was significantly lower than controls for four years, but no differences existed between fertilization levels, and the effect disappeared after four years, indicating that intrinsic water use efficiency (A/g sub(s)) increased in response to fertilization. Earlywood super(13)C showed similar trends but was more variable. Latewood d super(18)O increased significantly above controls by 62ppt in all treatments, but the duration differed with treatment level, with the effect being longer for higher levels of fertilization and lasting as long as nine years after fertilization. Because source water and relative humidity were the same between experimental plots, we interpreted the d super(18)O increase with treatment as a decrease in leaf-level transpiration. Earlywood d super(18)O did not show any treatment effects. Because the Pacific Northwest has a mediterranean climate with dry summers, we speculated that fertilization caused a substantial increase in leaf area, causing the trees to transpire themselves into drought stress during the late summer. We estimate from the d super(18)O data that stomatal conductance (g sub(s)) was reduced by 630%. Using the super(13)C data to estimate assimilation rates (A), A during the late season was also reduced by 20-30%. If leaf-level A decreased, but BAI increased, we estimated that leaf area on those trees must have increased by fourfold with the highest level of treatment within this stand. This increase in leaf area resulting from fertilization caused a hydraulic imbalance within the trees that lasted as long as nine years after treatment at the highest levels of fertilization.

Scharold, T.R. Angradi, T.D. Corry, E.W. Schwieger and J.R. Kelly. 2009. Trophic status of three large Missouri River reservoirs. Lake Reserv. Manage. 25:176-190. Probability-based surveys conducted between 2001-2004 characterized the three large reservoirs of the Missouri River--Lake Oahe, Lake Sakakawea, and Fort Peck Lake--as mesotrophic to eutrophic, phosphorus (P) limited, and generally supporting cold water habitat (bottom waters 5 mg/L) in midsummer. Riverine zones were shallower, warmer, more eutrophic, and had lower DO and higher suspended matter concentrations than lacustrine zones. Similar, although more variable, differences were found between bays and open-water areas. Between sampling years, water levels decreased in each reservoir. In the first year of sampling, area-weighted mean reservoir trophic status index based on chlorophyll (TSIchl) was about 37 in all three reservoirs. Sixty percent of Oahe and Sakakawea and 40% of Fort Peck had TSIchl> 50. Trophic status index based on Secchi depth (TSISD) averaged about 50 in each reservoir across years. Because mean TSIchl< TSISD, light attenuation was considered to be silt, not algae, dominated. Trophic status index based on total P (TSITP) and the ratio of N:P concentrations indicated that the reservoirs were very P limited. Mean bottom temperature and DO concentration in Oahe were unchanged between years at about 19°C and 7.5 mg/L, respectively. Bottom temperatures in Sakakawea increased (from 15°C to 21°C) and DO concentration decreased (from 7.3 mg/L to 6.0 mg/L) with lower water levels. In Fort Peck, bottom temperature remained about 18°C, but DO concentration fell from 7.23 mg/L to 4.96 mg/L. Results show that surveys successfully characterized important environmental conditions throughout these large reservoirs.

The solution which is developed for the case of a single point source can be generalized to represent analogous situations with any number of separate point sources. A limiting case of special interest has a line source of constant concentration spanning the domain's upstream boundary. The work has relevance for improving understanding of reactive transport within various kinds of advection-dominated natural or engineered environments including rivers and streams, and bioreactors such as treatment wetlands. Simulations are used to examine quantitatively the impact that transverse dispersion (deviations from purely stochastic-convective flow) can have on mean concentration decline in the direction of flow. Results support the contention that transverse mixing serves to enhance the overall rate of reaction in such systems.

Its widespread environmental distribution, presence in human blood, and adverse effects in animal toxicity studies have triggered attention to its potential adverse effects to humans. PFOA is not metabolized and exhibits dramatically different serum/plasma half-lives across species. Estimated half-lives for humans, monkeys, mice, and female rats are 3-5 years, 20-30 days, 12-20 days, and 2-4h, respectively. Developmental toxicity is one of the most sensitive adverse effects associated with PFOA exposure in rodents, but its interpretation for risk assessment is currently hampered by the lack of understanding of the inter-species pharmacokinetics of PFOA. To address this uncertainty, a biologically supported dynamic model was developed whereby a two-compartment system linked via placental blood flow described gestation and milk production linked a lactating dam to a growing pup litter compartment. Postnatal serum levels of PFOA for 129S1/SvImJ mice at doses of 1mg/kg or less were reasonably simulated while prenatal and postnatal measurements for CD-1 mice at doses of 1mg/kg or greater were simulated via the addition of a biologically based saturable renal resorption description. Our results suggest that at low doses a linear model may suffice for describing the pharmacokinetics of PFOA while a more complex model may be needed at higher doses. Although mice may appear more sensitive based on administered dose of PFOA, the internal dose metrics estimated in this analysis indicate that they may be equal or less sensitive than rats.

They are activators of peroxisome proliferator-activated receptor-alpha (PPARa) and exhibit hepatocarcinogenic potential in rats. PFOS and PFOA are also developmental toxicants in rodents and PFOS has been shown to induce pulmonary deficits in rat offspring. Pregnant CD-1 mice were dosed with 0, 5, or 10mg/kg PFOS from gestation days 1-17. Transcript profiling was conducted on the fetal liver and lung. Results were contrasted to data derived from a previous PFOA study. PFOS-dependent changes were primarily related to activation of PPARa. No remarkable differences were found between PFOS and PFOA. Given that PPARa signaling is required for neonatal mortality in PFOA-treated mice but not those exposed to PFOS, the neonatal mortality observed for PFOS may reflect functional deficits related to the physical properties of the chemical rather than to transcript alterations.

Both are environmentally persistent and found in the serum of wildlife and humans. PFOS and PFOA are developmentally toxic in laboratory rodents. Exposure to these chemicals in utero delays development and reduces postnatal survival and growth. Exposure to PFOS on the last 4 days of gestation in the rat is sufficient to reduce neonatal survival. PFOS and PFOA are weak agonists of peroxisome proliferator activated receptor-alpha (PPARa). The reduced postnatal survival of neonatal mice exposed to PFOA was recently shown to depend on expression of PPARa. This study used PPARa knockout (KO) and 129S1/SvlmJ wild type (WT) mice to determine if PPARa expression is required for the developmental toxicity of PFOS. After mating overnight, the next day was designated gestation day (GD) 0. WT females were weighed and dosed orally from GD15 to 18 with 0.5% Tween-20, 4.5, 6.5, 8.5, or 10.5mg PFOS/kg/day. KO females were dosed with 0.5% Tween-20, 8.5 or 10.5mg PFOS/kg/day. Dams and pups were observed daily and pups were weighed on postnatal day (PND) 1 and PND15. Eye opening was recorded from PND12 to 15. Dams and pups were killed on PND15, body and liver weights recorded, and serum collected. PFOS did not affect maternal weight gain or body or liver weights of the dams on PND15. Neonatal survival (PND1-15) was significantly reduced by PFOS in both WT and KO litters at all doses. WT and KO pup birth weight and weight gain from PND1 to 15 were not significantly affected by PFOS exposure. Relative liver weight of WT and KO pups was significantly increased by the 10.5mg/kg dose. Eye opening of PFOS-exposed pups was slightly delayed in WT and KO on PND13 or 14, respectively. Because results in WT and KO were comparable, it is concluded that PFOS-induced neonatal lethality and delayed eye opening are not dependent on activation of PPARa.

However, the relationships between timing or route of exposure, and consequences in the MG have not been characterized. To address the effects of these variables on the onset and persistence of MG effects in female offspring, timed pregnant CD-1 dams received PFOA by oral gavage over various gestational durations. Cross-fostering studies identified the 5mg/kg dose, under either lactational- or intrauterine-only exposures, to delay MG development as early as postnatal day (PND) 1, persisting beyond PND 63. Intrauterine exposure during the final days of pregnancy caused adverse MG developmental effects similar to that of extended gestational exposures. These studies confirm a window of MG sensitivity in late fetal and early neonatal life, and demonstrate developmental PFOA exposure results in early and persistent MG effects, suggesting permanent consequences.

Methods development for the analysis of tissues and fluids from pregnant and lactating mice and their pups AN - 20558018; 9266550 AB - The number of studies involving the analysis of perfluorooctanoic acid (PFOA) has increased recently because PFOA is routinely detected in human blood samples from around the world. Recent studies with mice have shown that dosing pregnant dams with PFOA during gestation gives rise to a dose-dependent mortality in the litters, a reduction in neonatal body weight for the surviving pups, and subsequent deficits in mammary gland development when compared to control animals. The actual body burdens of PFOA in dams and pups associated with these endpoints have not been determined, in part due to a lack of robust analytical methods for these matrices. The goal of the current study was to develop reliable methods with acceptable performance characteristics for the analysis of PFOA in several matrices relevant to pregnant mouse studies. Dam and pup serum, amniotic fluid, urine, milk, mammary tissue, and whole mouse pups were isolated for method development and analysis. The resulting method provided excellent accuracy (92.1-111%) and reproducibility (relative standard deviation 4.3-21%) making them very useful for future studies. These methods were then applied to dosed animal fluids and tissues in order to conduct a thorough evaluation of the pharmacokinetics in utero. Resulting tissue specific measurements of PFOA in serum, amniotic fluid, urine, milk, mammary tissue, and whole pup homogenate will be used to more completely describe the dose-response relationships for the most sensitive health outcomes and inform pharmacokinetic models that are being developed and evaluated.

These receptors regulate important physiological processes that impact lipid homeostasis, inflammation, adipogenesis, reproduction, wound healing, and carcinogenesis. These nuclear receptors have important roles in reproduction and development and their expression may influence the responses of an embryo exposed to PPAR agonists. PPARs are relevant to the study of the biological effects of the perfluorinated alkyl acids as these compounds, including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), activate PPARa. Exposure of the rodent to PFOA or PFOS during gestation results in neonatal deaths, developmental delay and growth deficits. Studies in PPARa knockout mice demonstrate that the developmental effects of PFOA, but not PFOS, depend on expression of PPARa. This review provides an overview of PPARa, b, and g protein and mRNA expression during mouse, rat, and human development. The review presents the results from many published studies and the information is organized by organ system and collated to show patterns of expression at comparable developmental stages for human, mouse, and rat. The features of the PPAR nuclear receptor family are introduced and what is known or inferred about their roles in development is discussed relative to insights from genetically modified mice and studies in the adult.

Here, we evaluate changes in protein and gene expression through two-dimensional difference gel electrophoresis (2D-DIGE) and Affymetrix arrays to identify potential modes of action involved in potassium bromate carcinogenicity. Male rats were exposed to potassium bromate in drinking water at concentrations of 0, 1, 20 and 400ppm for two weeks. Differential expression of glycolytic proteins including enolase 1 (Eno1), triosephosphate isomerase 1 (Tpi1) and glyceraldehyde-3-phosphate dehydrogenase (Gapdh) suggests that bromate toxicity is associated with changes in energy consumption and utilization in renal cells involving up-regulation of glycolytic processes that may be the result of altered mitochondrial function. Several alterations in glycolysis and mitochondrial gene transcripts were also observed to be consistent with this mode of action. These studies provide insight into early events in renal cell physiology altered by bromate exposure. gel electrophoresis JF - Food and Chemical Toxicology AU - Ahlborn, G J AU - Delker, DA AU - Roop, B C AU - Geter AU - Allen, J W AU - DeAngelo, AB AU - Winnik, WM AD - National Health and Environmental Effects Research Laboratory, Environmental Carcinogenesis Division, B143-06, 109 T.W.

Part 2: Disposition of PFOA in tissues and fluids from pregnant and lactating mice and their pups AN - 20556862; 9266614 AB - Previous studies in mice with multiple gestational exposures to perfluorooctanoic acid (PFOA) demonstrate numerous dose dependent growth and developmental effects which appeared to worsen if offspring exposed in utero nursed from PFOA-exposed dams. To evaluate the disposition of PFOA in the pregnant and lactating dam and her offspring, time-pregnant CD-1 mice received a single 0, 0.1, 1, or 5mg PFOA/kg BW dose (n=25/dose group) by gavage on gestation day 17. Maternal and pup fluids and tissues were collected over time. Pups exhibited significantly higher serum PFOA concentrations than their respective dams, and their body burden increased after birth until at least postnatal day 8, regardless of dose. The distribution of milk:serum PFOA varied by dose and time, but was typically in excess of 0.20. These data suggest that milk is a substantial PFOA exposure route in mice and should be considered in risk assessment modeling designs for this compound.

In mouse and rat liver these compounds elicit transcriptional and phenotypic effects similar to peroxisome proliferator chemicals (PPC) that work through the nuclear receptor peroxisome proliferator-activated receptor alpha (PPARa). Recent studies indicate that along with PPARa other nuclear receptors are required for transcriptional changes in the mouse liver after PFOA exposure including the constitutive activated receptor (CAR) and pregnane X receptor (PXR) that regulate xenobiotic metabolizing enzymes (XME). To determine the potential role of CAR/PXR in mediating effects of PFAAs in rat liver, we performed a meta-analysis of transcript profiles from published studies in which rats were exposed to PFOA or PFOS. We compared the profiles to those produced by exposure to prototypical activators of CAR, (phenobarbital (PB)), PXR (pregnenolone 16 alpha-carbonitrile (PCN)), or PPARa (WY-14,643 (WY)). As expected, PFOA and PFOS elicited transcript profile signatures that included many known PPARa target genes. Numerous XME genes were also altered by PFOA and PFOS but not WY. These genes exhibited expression changes shared with PB or PCN. Reexamination of the transcript profiles from the livers of chicken or fish exposed to PFAAs indicated that PPARa, CAR, and PXR orthologs were not activated. Our results indicate that PFAAs under these experimental conditions activate PPARa, CAR, and PXR in rats but not chicken and fish. Lastly, we discuss evidence that human populations with greater CAR expression have lower body burdens of PFAAs.

The objective of this research was to determine whether effective fresh water dispersants can be designed in case this technology is ever considered for use in fresh water environments. Previous studies on the chemical dispersion of crude oil in fresh water neither identified the dispersants that were investigated nor described the chemistry of the surfactants used. This information is necessary for developing a more fundamental understanding of chemical dispersion of crude oil at low salinity. Therefore, we evaluated the relationship between surfactant chemistry and dispersion effectiveness. We found that dispersants can be designed to drive an oil slick into the freshwater column with the same efficiency as in salt water as long as the hydrophilic-lipophilic balance is optimum.

Current methodologies focus first on identifying genotoxicants under the premise that agents capable of directly damaging DNA are most likely to be carcinogenic to humans. Emphasis on the distinction between genotoxic and non-genotoxic carcinogens is also motivated by assumed implications for the dose-response curve; it is purported that genotoxicants would lack a threshold in the low dose region, in contrast to non-genotoxic agents. However, for the vast majority of carcinogens, little if any empirical data exist to clarify the nature of the cancer dose-response relationship at low doses in the exposed human population. Recent advances in scientific understanding of cancer biology-and increased appreciation of the multiple impacts of carcinogens on this disease process-support the view that environmental chemicals can act through multiple toxicity pathways, modes and/or mechanisms of action to induce cancer and other adverse health outcomes. Moreover, the relationship between dose and a particular outcome in an individual could take multiple forms depending on genetic background, target tissue, internal dose and other factors besides mechanisms or modes of action; inter-individual variability and susceptibility in response are, in turn, key determinants of the population dose-response curve. New bioanalytical approaches (e.g., transcriptomics, proteomics, and metabolomics) applied in human, animal and in vitro studies could better characterize a wider array of hazard traits and improve the ability to predict the potential carcinogenicity of chemicals.

Daily samples (24-h) were collected at two locations, one approximately 10 m and the other 275 m perpendicular from the road. Concentrations of OC were similar between near (mean = 7.6 kg m super(-) super(3)) and far (8.0 kg m super(-) super(3)) locations, but concentrations of most organic species at the near site were between 1.5 and 2 times higher than those at the far site.

The conventional method first uses trypsin to detach cells from their growth surface. This inevitably changes the profile of cellular metabolites since the detachment of cells from the extracellular matrix alters their physiology. This conventional method also includes time consuming wash/centrifuge steps after trypsinization, but prior to quenching cell activity. During this time, a considerable portion of intracellular metabolites are lost, rendering the conventional method less than ideal for application to metabolomics. We report here a novel sample preparation method for metabolomics applications using adherent mammalian cells, which eliminates the time consumption and physiological stress of the trypsinization and wash/centrifuge steps. This new method was evaluated in the study of metabolic changes caused by 17 alpha -ethynylestradiol (EE2) in estrogen receptor (ER)-positive MCF-7 and ER-negative MDA-MB-231 human breast cancer cell lines using NMR spectroscopy. The results demonstrated that our direct cell quenching method is rapid, effective, and exhibits greater metabolite retention, providing an increase of approximately a factor of 50 compared to the conventional method.

9165990 AB - The numerous buildings that became contaminated with Bacillus anthracis (the bacterium causing the disease anthrax) in 2001, and more recent B. anthracis - related events, point to the need to have effective decontamination technologies for buildings contaminated with biological threat agents. The U.S. Government developed a portable chlorine dioxide (ClO sub(2)) generation system to decontaminate buildings contaminated with B. anthracis spores, and this so-called mobile decontamination trailer (MDT) prototype was tested through a series of three field trials. The first test of the MDT was conducted at Fort McClellan in Anniston, AL. during October 2004. Four test attempts occurred over two weekends; however, a number of system problems resulted in termination of the activity prior to any ClO sub(2) introduction into the test building. After making several design enhancements and equipment changes, the MDT was subjected to a second test. During this test, extensive leak checks were made using argon and nitrogen in lieu of chlorine gas; each subsystem was checked for functionality, and the MDT was operated for 24h. This second test demonstrated the MDT flow and control systems functioned satisfactorily, and thus it was decided to proceed to a third, more challenging field trial. In the last field test, ClO sub(2) was generated and routed directly to the scrubber in a 12-h continuous run. Measurement of ClO sub(2) levels at the generator outlet showed that the desired production rate was not achieved. Additionally, only one of the two scrubbers performed adequately with regard to maintaining ClO sub(2) emissions below the limit.

AN - 67221165; 19393156 AB - Determination of an individual's aggregate dietary ingestion of pesticides entails analysis of a difficult sample matrix. Permethrin-specific molecularly imprinted polymer (MIP) solid-phase extraction cartridges were developed for use as a sample preparation technique for a composite food matrix. Vortexing with acetonitrile and centrifugation were found to provide optimal extraction of the permethrin isomers from the composite foods. The acetonitrile (with 1% acetic acid) was mostly evaporated and the analytes reconstituted in 90:10 water/acetonitrile in preparation for molecularly imprinted solid-phase extraction. Permethrin elution was accomplished with acetonitrile and sample extracts were analyzed by isotope dilution gas chromatography-ion trap mass spectrometry. Quantitation of product ions provided definitive identification of the pesticide isomers. The final method parameters were tested with fortified composite food samples of varying fat content (1%, 5%, and 10%) and recoveries ranged from 99.3% to 126%. Vegetable samples with incurred pesticide levels were also analyzed with the given method and recoveries were acceptable (81.0-95.7%). Method detection limits were demonstrated in the low ppb range. Finally, the applicability of the MIP stationary phase to extract other pyrethroids, specifically cyfluthrin and cypermethrin, was also investigated. JF - Journal of chromatography.

PFOA is found in the sera and tissues of wildlife and humans throughout the world, but is especially high in the sera of children compared to adults. These studies in CD-1 mice aim to determine the latent health effects of PFOA following: (1) an in utero exposure, (2) an in utero exposure followed by ovariectomy (ovx), or (3) exposure as an adult. Mice were exposed to 0, 0.01, 0.1, 0.3, 1, 3, or 5 mg PFOA/kg BW for 17 days of pregnancy or as young adults. Body weight was reduced in the highest doses on postnatal day (PND) 1 and at weaning. However, the lowest exposures (0.01-0.3 mg/kg) significantly increased body weight, and serum insulin and leptin (0.01-0.1 mg/kg) in mid-life after developmental exposure. PFOA exposure combined with ovx caused no additional increase in mid-life body weight. At 18 months of age, the effects of in utero PFOA exposure on body weight were no longer detected. White adipose tissue and spleen weights were decreased at high doses of PFOA in intact developmentally exposed mice, and spleen weight was reduced in PFOA-exposed ovx mice. Brown adipose tissue weight was significantly increased in both ovx and intact mice at high PFOA doses. Liver weight was unaffected in late life by these exposure paradigms. Finally, there was no effect of adult exposure to PFOA on body weight. These studies demonstrate an important window of exposure for low-dose effects of PFOA on body weight gain, as well as leptin and insulin concentrations in mid-life, at a lowest observed effect level of 0.01 mg PFOA/kg BW. The mode of action of these effects and its relevance to human health remain to be explored.

During July-September 2006, an intensive study was undertaken to discern the degree of local source influence. Source-receptor relationships were explored by establishing a set of wet deposition sites in and around Steubenville, Ohio. For the three month period of study, volume-weighted mean Hg concentrations observed at the eight sites ranged from 10.2 to 22.3 ng L-1, but this range increased drastically on an event basis with a maximum concentration of 89.4 ng L-1 and a minimum concentration of 4.1 ng L-1. A subset of events was explored in depth, and the degree of variability in Hg concentrations between sites was linked to the degree of local source enhancement. Samples collected at sites less than 1 km from coal-fired utility stacks (near-field) exhibited up to 72% enhancement in Hg concentrations over regionally representative samples on an event basis. Air mass transport and precipitating cell histories were traced in order to evaluate relationships between local point sources and receptor sites. It was found that the interaction of several dynamic atmospheric parameters combined to favor local Hg concentration enhancement over the more regional contribution. When significant meteorological factors (wind speed at time of maximum rain rate, wind speed 24 h prior to precipitation, mixing height, and observed ceiling) were explored, it was estimated that during summertime precipitation, 42% of Hg concentration in near-field samples could be attributed to the adjacent coal-fired utility source.

AN - 67406491; 19544908 AB - The ability of selenium (Se) to moderate mercury (Hg) toxicity is well established in the literature. Mercury exposures that might otherwise produce toxic effects are counteracted by Se, particularly when Se:Hg molar ratios approach or exceed 1. We analyzed whole body Se and Hg concentrations in 468 fish representing 40 species from 137 sites across 12 western U.S. states. The fish samples were evaluated relative to a published wildlife protective Hg threshold (0.1 sg Hg x g(-1) wet wt.), the currenttissue based methylmercury (MeHg) water quality criterion (WQC) for the protection of humans (0.3 microg Hg x g(-1) wet wt) and to presumed protections against Hg toxicity when Se:Hg molar ratios are >1. A large proportion (56%) of our total fish sample exceeded the wildlife Hg threshold, whereas a smaller, but significant proportion (12%), exceeded the MeHg WQC. However, 97.5% of the total fish sample contained more Se than Hg (molar ratio >1) leaving only 2.5% with Se: Hg ratios <1. All but one of the fish with Se:Hg <1, were of the genus Ptychochelius (pikeminnow). Scientific literature on Se counteracting Hg toxicity and our finding that 97.5% of the freshwater fish in our survey have sufficient Se to potentially protect them and their consumers against Hg toxicity suggests that Se in fish tissue (Se:Hg molar ratio) must be considered when assessing the potential toxic effects of Hg.

The objective of this work was to develop a more physiologically and environmentally relevant model of air pollutant deposition on cultures of human primary airway epithelial cells. We hypothesize that the toxicology of inhaled particulate matter depends strongly on both the particulate dispersion state and the mode of delivery to cells. Our exposure system employs a combination of unipolar charging and electrostatic force to deposit particles directly from the air onto cells grown at an air-liquid interface in a heated, humidified exposure chamber. Normal human bronchial epithelial cells exposed to concentrated, coarse ambient particulate matter in this system expressed increased levels of inflammatory biomarkers at 1 h following exposure and relative to controls exposed to particle-free air. More importantly, these effects are seen at particulate loadings that are 1-2 orders of magnitude lower than levels applied using traditional in vitro systems.

Higher total mercury (THg) in environmental compartments (surface water, soil, flocculent detrital material (floc), and periphyton) generally occurred in the northern and central Everglades, but higher THg in water and periphyton in the Everglades National Park was an exception. Multiple biogeochemical characteristics, such as surface water dissolved organic matter (DOCSW), pH, chloride, and compositional properties of solid compartments (soil and floc), were identified to be important factors controlling THg distribution. Methylmercury (MeHg) was also higher in the northern Everglades for water, soil, and floc, but not for periphyton. Higher mosquitofish THg and bioaccumulation factor were observed in the central and southern Everglades, partially in accordance with periphyton MeHg distribution, but not in the 'hot spot' areas of water, soil, or floc MeHg. The discrepancy in mercury bioaccumulation and mercury distribution in environmental compartments suggests that in addition to MeHg production, biogeochemical controls that make MeHg available to aquatic organisms, such as DOCSW and compositional properties of soil and floc, are important in mercury bioaccumulation.

It is described in detail with an example of its application to SO2 data from East St. Louis, IL. The model uses nonparametric kernel smoothing methods to apportion the observed average concentration of a pollutant to sectors defined by ranges of wind direction and speed. Formulas are given for the uncertainty of all of the important components of the model, and these are found to give nearly the same uncertainties as blocked bootstrap estimates of uncertainty. The model was applied to data for the first quarter (January, February, and March) of 2003, 2004, and 2005. The results for East St. Louis show that almost 50% of the average SO2 concentration can be apportioned to two 30 wide wind sectors containing a zinc smelter and a brewery; a nearby steel mill did not appear to have a significant impact on SO2 during this period.

However, MOA-based testing seldom has been used for assessing the ecological risk of chemicals. This is in part because past regulatory mandates have focused more on adverse effects of chemicals (reductions in survival, growth or reproduction) than the pathways through which these effects are elicited. A recent departure from this involves endocrine-disrupting chemicals (EDCs), where there is a need to understand both MOA and adverse outcomes. To achieve this understanding, advances in predictive approaches are required whereby mechanistic changes caused by chemicals at the molecular level can be translated into apical responses meaningful to ecological risk assessment. In this paper we provide an overview and illustrative results from a large, integrated project that assesses the effects of EDCs on two small fish models, the fathead minnow (Pimephales promelas) and zebrafish (Danio rerio). For this work a systems-based approach is being used to delineate toxicity pathways for 12 model EDCs with different known or hypothesized toxic MOA. The studies employ a combination of state-of-the-art genomic (transcriptomic, proteomic, metabolomic), bioinformatic and modeling approaches, in conjunction with whole animal testing, to develop response linkages across biological levels of organization. This understanding forms the basis for predictive approaches for species, endpoint and chemical extrapolation. Although our project is focused specifically on EDCs in fish, we believe that the basic conceptual approach has utility for systematically assessing exposure and effects of chemicals with other MOA across a variety of biological systems.

As demonstrated, alterations to the colon flora of mice pretreated with streptomycin allowed transient colonization by bacterial species normally excluded by host competition. A novel procedure is described for determining the colonization abilities of Aeromonas isolates under these conditions. The colonization rates of A. salmonicida, A. encheleia, and A. allosaccharophila were either negative or occurred randomly at low levels with respect to concentrations of the dosage consumed by the animals. In contrast, A. hydrophila, A. veronii biovar sobria, and A. caviae exhibited relatively high rates of mouse colon tissue colonization.

AN - 839682700; 14073208 AB - Dauphin Island is a segmented, microtidal barrier island, located in the northern Gulf of Mexico, approximately 8.0 km offshore from southwestern Alabama (United States). It was first mapped by Spanish explorers in 1519 but was not settled until 1699 after being claimed as a French possession. In 1707, the French officially named it Isle Dauphine. Maps of the island from this French colonial period reveal a different morphology than subsequent maps. The first American maps of Dauphin Island and Mobile Bay show two small islands (i.e., Pelican and Sand islands) offshore from the southeastern end of Dauphin Island. Passing storms have moved and reshaped both of these delta margin islands around the south-southwestern periphery of the submerged Mobile Bay ebb-tidal delta. Only in the past 25 years have the two islands combined to slowly move in a northwesterly arc toward Dauphin Island.

This paper reports mean and percentile estimates of the distributions of daily average per capita water ingestion for a number of age range groups. The age ranges, based on guidance from the US EPA's Risk Assessment Forum, are narrow for younger ages when development is rapid and wider for older ages when the rate of development decreases. Estimates are based on data from the United States Department of Agriculture's (USDA's) 1994-1996 and 1998 Continuing Survey of Food Intake by Individuals (CSFII). Water ingestion estimates include water ingested directly as a beverage and water added to foods and beverages during preparation at home or in local establishments. Water occurring naturally in foods or added by manufacturers to commercial products (beverage or food) is not included. Estimates are reported in milliliters (ml/person/day) and milliliters per kilogram of body weight (ml/kg/day). As a by-product of constructing estimates in terms of body weight of respondents, distributions of self-reported body weights based on the CSFII were estimated and are also reported here.Journal of Exposure Science and Environmental Epidemiology (2009) 19, 396-404; doi:10.1038/jes.2008.29; published online 14 May 2008 JF - Journal of Exposure Science and Environmental Epidemiology AU - Kahn, Henry D AU - Stralka, Kathleen AD - aOffice of Research and Development, National Center for Environmental Assessment, US EPA, Washington, District of Columbia, USA Y1 - 2009/05// PY - 2009 DA - May 2009 SP - 396 EP - 404 PB - Nature Publishing Group, The Macmillan Building London N1 9XW UK VL - 19 IS - 4 SN - 1559-0631, 1559-0631 KW - Toxicology Abstracts; Pollution Abstracts; Risk Abstracts KW - Risk assessment KW - Agriculture KW - age groups KW - Age KW - Beverages KW - Data processing KW - Byproducts KW - agriculture KW - Ingestion KW - EPA KW - USA KW - Body weight KW - Pollutants KW - Epidemiology KW - Food intake KW - Geriatrics KW - human populations KW - body weight KW - Internet KW - R2 23060:Medical and environmental health KW - P 6000:TOXICOLOGY AND HEALTH KW - X 24300:Methods UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/754885177?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ariskabstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.atitle=Estimated+daily+average+per+capita+water+ingestion+by+child+and+adult+age+categories+based+on+USDA%27s+1994-1996+and+1998+continuing+survey+of+food+intakes+by+individuals&rft.au=Kahn%2C+Henry+D%3BStralka%2C+Kathleen&rft.aulast=Kahn&rft.aufirst=Henry&rft.date=2009-05-01&rft.volume=19&rft.issue=4&rft.spage=396&rft.isbn=&rft.btitle=&rft.title=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.issn=15590631&rft_id=info:doi/10.1038%2Fjes.2008.29 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2010-09-01 N1 - Last updated - 2014-04-17 N1 - SubjectsTermNotLitGenreText - Agriculture; Risk assessment; Age; Data processing; Beverages; Epidemiology; Pollutants; Body weight; Food intake; Geriatrics; Internet; EPA; age groups; Byproducts; agriculture; human populations; Ingestion; body weight; USA DO - http://dx.doi.org/10.1038/jes.2008.29 ER - TY - JOUR T1 - Development and validation of a Daphnia magna four-day survival and growth test method. AN - 67543913; 19067494 AB - Zooplankton are an important part of the aquatic ecology of all lakes and streams. As a result, numerous methods have been developed to assess the quality of waterbodies using various zooplankton species. Included in these is the freshwater species Daphnia magna. Current test methods using D. magna involve acute lethality test methods ranging from 24 to 96 h in duration and chronic test methods with durations of 21 to 28 d. Whereas the current acute and chronic test methods are useful, a need exists for a shorter-duration test method that will provide a chronic or subchronic endpoint with this, species. In the present study, a 4-d, static-renewal survival and growth test was developed for use with D. magna. The test results were compared to performance criteria and results from 7-d survival and reproduction tests with Ceriodaphnia dubia to determine the level of comparability between the two methods. Results from the 4-d D. magna survival and growth test method indicated that this method will produce consistent results with various reference toxicant materials and provide data that are both reproducible and useful for detecting potential toxicity in aquatic environments.

AN - 67466419; 19583158 AB - A current re-engineering of the United States routine ambient monitoring networks intended to improve the balance in addressing both regulatory and scientific objectives is addressed in this paper. Key attributes of these network modifications include the addition of collocated instruments to produce multiple pollutant characterizations across a range of representative urban and rural locations in a new network referred to as the National Core Monitoring Network (NCore). The NCore parameters include carbon monoxide (CO), sulfur dioxide (SO2), reactive nitrogen (NOy), ozone (O3), and ammonia (NH3) gases and the major fine particulate matter (PM2.5) aerosol components (ions, elemental and organic carbon fractions, and trace metals). The addition of trace gas instruments, deployed at existing chemical speciation sites and designed to capture concentrations well below levels of national air quality standards, is intended to support both long-term epidemiological studies and regional-scale air quality model evaluation. In addition to designing the multiple pollutant NCore network, steps were taken to assess the current networks on the basis of spatial coverage and redundancy criteria, and mechanisms were developed to facilitate incorporation of continuously operating particulate matter instruments.

AN - 67464017; 19583154 AB - Lime treatment has been used in contaminated sediment management activities for many purposes such as dewatering, improvement of physical properties, and reducing contaminant mobility. Exothermic volatilization of volatile organic compounds from lime-treated sediment is well known, but potential aerosolization of bioaerosol components has not been evaluated. A physical model of a contaminated sediment treatment and airborne transport process and an experimental protocol were developed to identify specific bioaerosol components (bacteria, fungi, cell structural components, and particles) that may be aerosolized and transported. Key reaction variables (amount of lime addition, rate of lime addition, mixing energy supplied) that may affect the aerosolization of bioaerosol components were evaluated. Lime treatment of a sediment contaminated with heavy metals, petroleum-based organics, and microorganisms increased the sediment pH and solids content. Lime treatment reduced the number of water-extractable bacteria and fungi in the sediment from approximately 10(6) colony-forming units (CFU) x mL(-1) to less than the detection limit of 10(3) CFU x mL(-1). This reduction was seen immediately for bacteria and within 21 days for fungi. Lime treatment immediately reduced the amount of endotoxin in the sediment, but the effects of lime treatment on beta-D-glucan could not be determined. The temperature of the treated sediment was linearly related to the amount of lime added within the range of 0-25%. Bacteria were aerosolized during the treatment trials, but there was no culturable evidence of aerosolization of fungi, most likely because of either their particular growth stage or relatively larger particle size that reduced their aerosolization potential and their collection into the impingers. Nonbiological particles, endotoxin, and beta-D-glucan were not detected in air samples during the treatment trials. The amount of lime added to the reaction beaker and the relative amount of mixing energy supplied to the reaction significantly affected the aerosolization ratio of bacteria (amount of aerosolized bacteria divided by the amount of bacteria in untreated sediment) from the reaction beaker. The rate of lime addition did not significantly affect the aerosolization ratio of bacteria. The aerosolization results suggest that exposure to bacteria is possible with sediment treatment activities, but the hazard level could not be determined because speciation of the aerosolized bacteria for pathogen identification was not performed, and health and safety standards and criteria for bioaerosol components have not been developed. Quantitative scaling analysis and whether the system represents actual environmental conditions were not studied.

AN - 67463872; 19583162 AB - Knowledge of the emission rate and release characteristics is necessary for estimating pollutant fate and transport. Because emission measurements at a facility's fence line are generally not readily available, environmental agencies in many countries are using emission factors (EFs) to indicate the quantity of certain pollutants released into the atmosphere from operations such as welding. The amount of fumes and metals generated from a welding process is dependent on many parameters, such as electrode composition, voltage, and current. Because test reports on fume generation provide different levels of detail, a common approach was used to give a test report a quality rating on the basis of several highly subjective criteria; however, weighted average EFs generated in this way are not meant to reflect data precision or to be used for a refined risk analysis. The 95% upper confidence limit (UCL) of the unknown population mean was used in this study to account for the uncertainty in the EF test data. Several parametric UCLs were computed and compared for multiple welding EFs associated with several mild, stainless, and alloy steels. Also, several nonparametric statistical methods, including several bootstrap procedures, were used to compute 95% UCLs. For the nonparametric methods, a distribution for calculating the mean, standard deviation, and other statistical parameters for a dataset does not need to be assumed. There were instances when the sample size was small and instances when EFs for an electrode/process combination were not found. Those two points are addressed in this paper. Finally, this paper is an attempt to deal with the uncertainty in the value of a mean EF for an electrode/process combination that is based on test data from several laboratories. Welding EFs developed with a defined level of confidence may be used as input parameters for risk assessment.

AN - 67301027; 19479009 AB - Our objective was to examine experimental and epidemiologic studies pertaining to immune-related, and specifically autoimmune-related, effects of trichloroethylene (TCE). We performed a literature search of PubMed and reviewed bibliographies in identified articles. We then systematically reviewed immune-related data, focusing on clinical and immunologic features and mechanistic studies. Studies conducted in MRL+/+ lupus mice report an accelerated autoimmune response in relation to exposure to TCE or some metabolites. Effects have been reported after 4 weeks of exposure to TCE at doses as low as 0.1 mg/kg/day in drinking water and have included increased antinuclear antibodies and interferon-gamma (IFN-gamma) and decreased secretion of interleukin-4 (IL-4), consistent with an inflammatory response. Autoimmune hepatitis, inflammatory skin lesions, and alopecia have been found after exposures of 32-48 weeks. Recent mechanistic experiments in mice examined oxidative stress and, specifically, effects on lipid-peroxidation-derived aldehydes in TCE-induced autoimmune disease. Two studies in humans reported an increase in IL-2 or IFN-gamma and a decrease in IL-4 in relation to occupational or environmental TCE exposure. Occupational exposure to TCE has also been associated with a severe, generalized hypersensitivity skin disorder accompanied by systemic effects, including hepatitis. In three case-control studies of scleroderma with a measure of occupational TCE exposure, the combined odds ratio was 2.5 [95% confidence interval (CI), 1.1-5.4] in men and 1.2 (95% CI, 0.58-2.6) in women. The consistency among the studies and the concordance between the studies in mice and humans support an etiologic role of TCE in autoimmune disease. Multisite collaborations and studies of preclinical immune markers are needed to further develop this field of research.

AN - 67130132; 18712500 AB - A life table response experiment (LTRE) was used to quantify the population-level effects of continuous, multigeneration cadmium exposure on two strains of the freshwater gastropod, Biomphalaria glabrata: the parasite-resistant BS90 and parasite-susceptible NMRI strains. Snails were exposed to waterborne cadmium for three consecutive generations. Survival, growth, and reproduction were measured empirically and incorporated into a stage-based, deterministic population model. Cadmium significantly affected hatching success, time to maturity, and juvenile and adult survival in both strains. There were significant effects of generation on fecundity, hatching success, time to maturity and juvenile survival in NMRI, and time to maturity and adult survival in BS90. Cadmium significantly affected the population growth rate, lambda, in BS90. Cadmium, generation, and the cadmium x generation interaction had significant effects on lambda in NMRI. At the high cadmium exposure, lambda for NMRI showed a decrease from generation 1 to generation 2, followed by an increase from generation 2 to generation 3. The lambda value in high-cadmium BS90 steadily decreased over the three generations, while NMRI at this same concentration was similar to the controls. The results indicate that strain-specific differences in response to multigeneration cadmium exposure are evident in B. glabrata. Moreover, effects seen in the first generation are not necessarily indicative of effects in subsequent generations. Changes in lambda over the course of the three-generation exposure suggest that acclimation and/or adaptation to cadmium may have occurred, particularly in NMRI at the high cadmium exposure level.

AN - 67104864; 18926592 AB - Malignant pleural mesothelioma is an aggressive cancer. Chemotherapy with cisplatin and pemetrexed can improve overall survival but has a toxic profile. Substitution of cisplatin with carboplatin may avoid some potential side-effects. Therefore, we undertook a retrospective review to assess the effectiveness and tolerability of carboplatin and pemetrexed in patients with malignant pleural mesothelioma in clinical practice. Patients with malignant pleural mesothelioma who had been treated with carboplatin and pemetrexed were retrospectively identified from pharmacy databases. The endpoints were disease control rate, time to treatment failure, clinical improvement rate and overall survival. We also evaluated any significant haematological and non-haematological toxicities. A total of 49 patients were identified. Of 45 evaluable cases, the disease control rate was achieved in 34 patients (69%, 95% CI 55-82, intention to treat analysis). The clinical response rate was achieved in 34 out of 49 patients (69%, 95% CI 55-82). The median time to treatment failure was 4.6 months (95% CI 3.4-5.8) and median overall survival was 14 months (95% CI 9.5-18.5). Grade 3/4 haematological toxicities were observed in 7 patients (14.3%). Grade 3/4 non-haematological toxicities were seen in 12 patients (24.5%). No toxic deaths were recorded. The combination of carboplatin and pemetrexed may be a viable option in the treatment of malignant pleural mesothelioma.

AN - 67089039; 19250655 AB - An air quality study was performed outside a cluster of schools in the East Harlem neighborhood of New York City. PM(2.5) and black carbon concentrations were monitored using real-time equipment with a one-minute averaging interval. Monitoring was performed at 1:45-3:30 PM during school days over the period October 31-November 17, 2006. The designated time period was chosen to capture vehicle emissions during end-of-day dismissals from the schools. During the monitoring period, minute-by-minute volume counts of idling and passing school buses, diesel trucks, and automobiles were obtained. These data were transcribed into time series of number of diesel vehicles idling, number of gasoline automobiles idling, number of diesel vehicles passing, and number of automobiles passing along the block adjacent to the school cluster. Multivariate regression models of the log-transform of PM(2.5) and black carbon (BC) concentrations in the East Harlem street canyon were developed using the observation data and data from the New York State Department of Environmental Conservation on meteorology and background PM(2.5). Analysis of variance was used to test the contribution of each covariate to variability in the log-transformed concentrations as a means to judge the relative contribution of each covariate. The models demonstrated that variability in background PM(2.5) contributes 80.9% of the variability in log[PM(2.5)] and 81.5% of the variability in log[BC]. Local traffic sources were demonstrated to contribute 5.8% of the variability in log[BC] and only 0.43% of the variability in log[PM(2.5)]. Diesel idling and passing were both significant contributors to variability in log[BC], while diesel passing was a significant contributor to log[PM(2.5)]. Automobile idling and passing did not contribute significant levels of variability to either concentration. The remainder of variability in each model was explained by temperature, along-canyon wind, and cross-canyon wind, which were all significant in the models.

The model is defined in the Cartesian coordinate system, and its electromagnetic properties might vary in the x- and z-directions, but not in the y-direction. Wave propagation in the x- and z-directions is simulated with the finite-difference method, and wave propagation in the y-direction is simulated with an analytic function. The absorbing boundaries on the finite-difference grid are perfectly matched layers that have been modified to make them compatible with the hybrid method. The accuracy of these numerical Green's functions is assessed by comparing them with independently calculated Green's functions. For a homogeneous model, the magnitude errors range from -4.16% through 0.44%, and the phase errors range from -0.06% through 4.86%. For a layered model, the magnitude errors range from -2.60% through 2.06%, and the phase errors range from -0.49% through 2.73%. These numerical Green's functions might be used for forward modeling and full waveform inversion.

Similar to the injection of hazardous wastes, before injection of CO (sub 2) , operators of geologic sequestration projects may need to demonstrate nonendangerment of groundwater resources during the lifetime of the project. Future requirements related to CO (sub 2) accounting and transfer credits may require operators to evaluate and quantify any surface releases. Subsurface fluid flow computational models have been advocated as an integral tool in predicting and tracking the migration of CO (sub 2) or mobilized constituents. Modeling the injection and sequestration of CO (sub 2) poses unique challenges, such as the need to properly characterize CO (sub 2) transport properties across a large range of temperatures and pressures, and the need to couple multiphase flow, reactive transport, and geomechanical processes. In addition, the volumes of CO (sub 2) that may be injected are largely unprecedented, and an appropriate amount of site characterization across the potentially impacted area will be difficult. In the last several years, there have been several research studies specifically modeling the problem of subsurface injection of CO (sub 2) . Existing studies demonstrate the use of modeling in project design, site characterization, assessments of leakage, and site monitoring. Particularly informative components of existing modeling studies include parameter sensitivity analyses, evaluation of numerical artifacts, code comparison, and demonstrations of model calibration to site monitoring data.

Agricultural soils are often a source but can also be a sink of CO (sub 2) . Regional and larger scale estimates of GHG emissions are usually obtained using IPCC emission factor methodology, which is associated with high uncertainty. To more realistically represent GHG emissions we used the DAYCENT biogeochemical model for non-rice major crop types (corn, wheat, soybean). IPCC methodology estimates N losses from croplands based solely on N inputs. In contrast, DAYCENT accounts for soil class, daily weather, historical vegetation cover, and land management practices such as crop type, fertilizer additions, and cultivation events. Global datasets of weather, soils, native vegetation, and cropping fractions were mapped to a 1.9 degrees X1.9 degrees resolution. Non-spatial data (e.g., rates and dates of fertilizer applications) were assumed to be identical within crop types across regions. We compared model generated baseline GHG emissions and N losses for irrigated and rainfed cropping with land management alternatives intended to mitigate GHG emissions. Reduced fertilizer resulted in lower N losses, but crop yields were reduced by a similar proportion. Use of nitrification inhibitors and split fertilizer applications both led to increased ( nearly equal 6%) crop yields but the inhibitor led to a larger reduction in N losses ( nearly equal 10%). No-till cultivation, which led to C storage, combined with nitrification inhibitors, resulted in reduced GHG emissions of nearly equal 50% and increased crop yields of nearly equal 7%.

Applying the Environmental Emissions Index to quantify environmental performance trends from routinely reported data AN - 37162769; 3877646 AB - Reported emissions data were collated for 35 pharmaceutical-manufacturing installations and 18 power stations holding IPPC licences in Ireland. Consistent and essentially complete sectoral emissions time-series were generated, covering 2002-2006 for the pharmaceutical sector, and 2001-2006 for the electricity-generating sector. Applying the Environmental Emissions Index (EEI) to reported emissions indicated environmental performance improvements of 35 and 30%, respectively, for these two sectors. However, considerable uncertainty was attributed to reporting of heavy metals, NO"x and NMVOC emissions at the installation level, and overall NMVOC emissions from the pharmaceutical sector appeared to be considerably under-reported. The fixed average toxicity factor applied to NMVOC emissions in the EEI may deviate from potential temporal changes in the NMVOC compound mix. Overall, reporting uncertainties were found to have a greater impact on EEI outputs than assumptions made in the EEI model, and including an estimate of total sectoral NMVOC emissions reduced the pharmaceutical sector's environmental performance improvement to 24%. The EEI facilitates the comparison and visualisation of reported emissions, integrating them into environmental performance trends. It should optimise interpretation of abundant, detailed, and underutilised 'bottom-up' emissions data generated by IPPC installations. For Ireland's pharmaceutical sector, these data are considerably more comprehensive than EPER data.

Devising a quantitative science-based and policy-weighted Environmental Emissions Index AN - 37162472; 3877645 AB - This paper describes the derivation of an Environmental Emissions Index (EEI) intended to quantify the environmental performance of Integrated Pollution Prevention and Control (IPPC) installations and sectors. Characterisation and normalisation methods used in lifecycle analyses were applied to 20 routinely reported emissions parameters, pertaining to six environmental impact categories. Distance to policy targets for relevant emissions were used to weight impact categories, and link the EEI to policy priorities. Ireland and the EU15 were considered as scales of context. The European Pollutant Emission Register was a convenient source of normalisation data, but restricted the context of the EEI to industrial emissions, and distorted outputs. Using national and EU15 total loading estimates for normalisation resulted in an EEI that better reflected the relative contribution of reported emissions towards overall environmental pressures. Using Ireland's pharmaceutical sector as a case study indicated that weighting factors, and the toxicity range of NMVOC emissions, were the largest sources of EEI uncertainty. Through the integration of inventory data, scientific characterisation, and policy targets, the EEI translates reported emissions data from IPPC installations and sectors into a benchmark of environmental performance. It may be regarded as an evolving tool of potential utility to regulators and policy makers.

The opportunity to restore ecosystems through this market rather than establish plantations is demonstrated by an Australian case study. In the state of Queensland there are vast areas that have been cleared relatively recently and could be restored to ecosystems with high resilience and important biodiversity values with appropriate management. In order to foster opportunities for carbon accumulation through ecosystem recovery spatially explicit information on sequestration rates, management recommendations, and clear definitions of ancillary biodiversity benefits need to be defined.

This study was carried out to respond to current concerns and challenges in SR-AOTs, including (i) need of heterogeneous activation of sulfate salts using transition metal oxides, (ii) nanoscaling of the metal oxide catalysts for high catalytic activity and promising properties with respect to leaching, and (iii) easy removal and recovery of the catalytic materials after their applications for water and wastewater treatments. In this study, we report a novel approach of using Fe-Co mixed oxide nanocatalysts for the heterogeneous activation of peroxymonosulfate (PMS) to generate SRs targeting the decomposition of 2,4-dichlorophenol, and especially focus on some synthesis parameters such as calcination temperature, Fe/Co contents, and TiO2 support. The physicochemical properties of the catalysts were investigated using porosimetry, XRD, HR-TEM, H2-TPR, and XPS. Ferromagnetic CoFe2O4 composites formed by thermal oxidation of a mixed phase of Fe and Co exhibited significant implications for the efficient and environmentally friendly activation of PMS, including (i) the cobalt species in CoFe2O4 are of Co(II), unlike Co3O4 showing some detrimental effects of Co(III) on the PMS activation, (ii) CoFe2O4 possesses suppressed Co leaching properties due to strong Fe-Co interactions (i.e. Fe-Co linkages), and (iii) Fe-Co catalysts in form of CoFe2O4 are easier to recover due to the unique ferromagnetic nature of CoFe2O4. In addition, the presence of Fe was found to be beneficial for enriching hydroxyl group content on the Fe-Co catalyst surface, which is believed to facilitate the formation of Co(II)-OH complexes that are vital for heterogeneous PMS activation.

To address this issue, the U.S. Environmental Protection Agency (EPA) and other organizations are developing chemical screening and prioritization programs. As part of these efforts, it is important to catalog, from widely dispersed sources, the toxicology information that is available. The main objective of this analysis is to define a list of environmental chemicals that are candidates for the U.S. EPA screening and prioritization process, and to catalog the available toxicology information. Data sources: We are developing ACToR (Aggregated Computational Toxicology Resource), which combines information for hundreds of thousands of chemicals from > 200 public sources, including the U.S. EPA, National Institutes of Health, Food and Drug Administration, corresponding agencies in Canada, Europe, and Japan, and academic sources. Data extraction: ACToR contains chemical structure information; physical-chemical properties; in vitro assay data; tabular in vivo data; summary toxicology calls (e.g., a statement that a chemical is considered to be a human carcinogen); and links to online toxicology summaries. Here, we use data from ACToR to assess the toxicity data landscape for environmental chemicals. Data synthesis: We show results for a set of 9,912 environmental chemicals being considered for analysis as part of the U.S. EPA ToxCast screening and prioritization program. These include high- and medium-production-volume chemicals, pesticide active and inert ingredients, and drinking water contaminants. Conclusions: Approximately two-thirds of these chemicals have at least limited toxicity summaries available. About one-quarter have been assessed in at least one highly curated toxicology evaluation database such as the U.S. EPA Toxicology Reference Database, U.S. EPA Integrated Risk Information System, and the National Toxicology Program.

The purpose of this paper is to describe EMAP-GRE using examples based on data collected in 2004-2006 with emphasis on an approach to determining reference conditions. EMAP-GRE includes the Upper Mississippi River, the Missouri River, and the Ohio River. Indicators include biotic assemblages (fish, macroinvertebrates, plankton, algae), water chemistry, and aquatic and riparian physical habitat. Reference strata (river reaches for which a single reference expectation is appropriate) were determined by ordination of the fish assemblage and examination of spatial variation in environmental variables. Least disturbed condition of fish assemblages for reference strata was determined by empirical modeling in which we related fish assemblage metrics to a multimetric stressor gradient. We inferred least disturbed condition from the y-intercept, the predicted condition when stress was least. Thresholds for dividing the resource into management-relevant condition classes for biotic indicators were derived using predicted least disturbed condition to set the upper bound on the least disturbed condition class. Also discussed are the outputs of EMAP-GRE, including the assessment document, multimetric indices of condition, and unbiased data supporting state and tribal Clean Water Act reporting, adaptive management, and river restoration.

Contributing basin area explained the majority of spatial variation (R super(2) = 0.57-0.63) in coho salmon overwinter survival (range = 0.02-0.63), with highest survival rates observed in smaller headwater and intermittent streams. Other habitat attributes, including proportional pool area, percent exposed bedrock substrate, percent broadleaf canopy cover, and adult salmon carcass density, were relatively poor predictors of survival. Indices of individual fish condition, including fall parr fork length, condition factor, and parasite infestation rates, were also relatively uninformative in coho salmon overwinter survival models. Coho salmon smolt length was primarily a function of length at the time of fall tagging, but stream type, contributing basin area (positive effect), thermal history (positive effect), and black spot infestation (i.e., trematode metacercariae; negative effect) were also important. The consistent, broad spatial gradients in overwinter survival observed in this study can help guide efforts designed to enhance coho salmon production in coastal streams and suggest that habitat protection, restoration, and enhancement strategies will be best guided by a whole-basin context.

Predictive climatic models have been extensively investigated to quantify the impacts. Palaeoclmatic investigations, on the other hand, show unequivocal and strong periodicity of climate variations in proxy evidence. Yet how to use the periodicity in future hydroclimatic timing and forecasting has received less attention. This paper examines the periodicity in Pleistocene-Holocene glacial-interglacial events and in modern precipitation records, and discusses a way in which the periodicity is used for hydroclimatic predictions. The analysis, based on published CO2, T (d2H) and d18O proxy data of polar ice cores and deep oceanic benthic fossils, shows a periodicity in a ~100, ~40 or 25 kyear duration consistent with Milankovitch orbital regulations during the glacial-interglacial periods. On a fine time scale, millennium and multi-decadal periodicity is observed in high-resolution proxy variations of Greenland ice cores and in instrumental precipitation records of the contiguous USA. A basic periodicity of decadal and multi-decadal changes in ~20 and ~10-15 year duration is apparent in wavelet frequency analysis of both ice core proxy and precipitation data. While the kyear-scale periodicity is found of global prevalence, the millennium and decadal variations vary in space and are region-specific. Based on these findings, a generalized time-downscaling hierarchy of periodicity is proposed as a potential approach for timing and forecasting future hydroclimatic conditions at a resolution relevant to the water resources engineering and management.

PM inhalation causes several adverse changes in cardiac function that are reflected in the electrocardiogram (ECG), including altered cardiac rhythm, myocardial ischemia, and reduced heart rate variability (HRV). The sensitivity and reliability of ECG-derived parameters as indicators of the cardiovascular toxicity of PM in rats are unclear. Objective: We hypothesized that spontaneously hypertensive (SH) rats are more susceptible to the development of PM-induced arrhythmia, altered ECG morphology, and reduced HRV than are Wistar Kyoto (WKY) rats, a related strain with normal blood pressure. Methods: We exposed rats once by nose-only inhalation for 4 hr to residual oil fly ash (ROFA), an emission source particle rich in transition metals, or to air and then sacrificed them 1 or 48 hr later. Results: ROFA-exposed SH rats developed nonconducted P-wave arrhythmias but no changes in ECG morphology or HRV. We found no ECG effects in ROFA-exposed WKY rats. ROFA-exposed SH rats also had greater pulmonary injury, neutrophil infiltration, and serum C-reactive protein than did ROFA-exposed WKY rats. Conclusions: These results suggest that cardiac arrhythmias may be an early sensitive indicator of the propensity for PM inhalation to modify cardiovascular function.

To explore the prospect of using a screen in an in vivo exposure scenario, we applied a commercially available multianalyte profile (MAP) of 58 serum biomarkers to rats exposed acutely to two anticholinesterase insecticides, chlorpyrifos (CHP) and carbaryl (CAR). Male, Long-Evans rats were dosed orally with 30mg/kg CHP, 75mg/kg CAR or the corn oil vehicle. Doses were selected based on their equivalent physiological effects (hypothermia and reduced motor activity). The animals were terminated 24h or 7 days after dosing. Serum was collected and analyzed for 58 biomarkers consisting primarily of cytokines, chemokines, and a few hormones. There were changes in six analytes (four up, two down) following CHP and eight analytes (five up, three down) following CAR at 24h. There were significant changes in only two biomarkers when measured 7 days after dosing with CHP. Overall, the MAP detected a broad spectrum of unique effects for CHP and CAR. It is concluded that the MAP is a useful tool to screen for in vivo effects of environmental toxicants and its use could lead to the discovery of novel mechanisms of action.

Three regional-scale atmospheric mercury models were tested: the Community Multiscale Air Quality (CMAQ) model, the Regional Modeling System for Aerosols and Deposition (REMSAD), and the Trace Element Analysis Model (TEAM). These models were each employed using three sets of lateral boundary conditions to test their sensitivity to intercontinental transport of mercury. The same meteorological and pollutant emission data were used in each simulation. Observations of wet deposition were obtained from the National Atmospheric Deposition Program' s Mercury Deposition Network. The regional models can explain 50 - 70% of the site-to-site variance in annual mercury wet deposition. CMAQ was found to have slightly superior agreement with observations of annual mercury deposition flux in terms of the mean value for all monitoring sites, but REMSAD showed the best correlation when measured by the coefficient of determination (2). With the exception of one CMAQ simulation, all of the models tended to simulate more wet deposition of mercury than was observed. TEAM exceeded the observed average annual wet deposition by 50% or more in all three of its simulations. CMAQ and REMSAD were better able to reproduce the observed seasonal distribution of mercury wet deposition than was TEAM, but TEAM showed the highest correlation for weekly wet deposition samples. An analysis of model accuracy at each observation site showed no obvious geographic patterns for correlation, bias, or error. Adjusting simulated mercury deposition on the basis of the difference between observed and simulated precipitation data improved the correlation and error scores for all of the models.

Neurological effects and other adverse health effects may also result from exposure during infancy, childhood, and adulthood. Although manufacture and use of PCBs were banned in the US in 1977, exposure to PCBs is a continuing concern due to the widespread distribution of these compounds in the environment and their persistence. The National Health and Nutrition Examination Survey provides PCB body burden measurements representative of the US population for the years 1999-2002. Interpretation of these data is challenging due to the large number of PCB congeners reported. We examined 6 PCB body burden metrics to identify an approach for summarizing the NHANES data and for characterizing changes over time in potential risks to children's health. We focused on women of childbearing age, defined here as 16-39 years, because in utero exposures have been associated with neurodevelopmental effects, and used only the 2001-2002 data because of higher detection rates. The 6 metrics, each consisting of different combinations of the 9 most frequently detected congeners, were as follows: total PCBs (all 9 congeners); highly chlorinated PCBs (2 congeners); dioxin-like PCBs (3 congeners, weighted by toxic equivalency factors); non-dioxin-like PCBs (6 congeners); a 4-congener metric (PCBs 118, 138, 153, and 180); and PCB-153 alone. The PCB metrics were generally highly correlated with each other. There was a strong association of PCB body burdens with age for all metrics. Median body burdens of Mexican American women were lower than those of non-Hispanic White and non-Hispanic Black women for 5 of the 6 metrics, and there were no significant differences in body burdens between the latter two groups. Body burdens of women with incomes above poverty level were greater than those for lower-income women at the median and 95th percentiles, but the differences were not statistically significant for any metric. We conclude that the 4-congener and total PCBs metrics are the most promising approaches for tracking changes in body burdens over time and for comparing body burdens of different subgroups in NHANES.

Increases in liver weight (hepatomegaly) have been reported to occur quickly in rodents after TCE exposure, with liver tumor induction reported in mice after long-term exposure. An integrated dataset for gavage and inhalation TCE exposure and oral data for exposure to two of its oxidative metabolites (TCA and DCA) was used, in combination with an updated and more accurate physiologically-based pharmacokinetic (PBPK) model, to examine the question as to whether the presence of TCA in the liver is responsible for TCE-induced hepatomegaly in mice. The updated PBPK model was used to help discern the quantitative contribution of metabolites to this effect. The update of the model was based on a detailed evaluation of predictions from previously published models and additional preliminary analyses based on gas uptake inhalation data in mice. The parameters of the updated model were calibrated using Bayesian methods with an expanded pharmacokinetic database consisting of oral, inhalation, and iv studies of TCE administration as well as studies of TCE metabolites in mice. The dose-response relationships for hepatomegaly derived from the multi-study database showed that the proportionality of dose to response for TCE- and DCA-induced hepatomegaly is not observed for administered doses of TCA in the studied range. The updated PBPK model was used to make a quantitative comparison of internal dose of metabolized and administered TCA. While the internal dose of TCA predicted by modeling of TCE exposure (i.e., mg TCA/kg-d) showed a linear relationship with hepatomegaly, the slope of the relationship was much greater than that for directly administered TCA. Thus, the degree of hepatomegaly induced per unit of TCA produced through TCE oxidation is greater than that expected per unit of TCA administered directly, which is inconsistent with the hypothesis that TCA alone accounts for TCE-induced hepatomegaly. In addition, TCE-induced hepatomegaly showed a much more consistent relationship with PBPK model predictions of total oxidative metabolism than with predictions of TCE area-under-the-curve in blood, consistent with toxicity being induced by oxidative metabolites rather than the parent compound. Therefore, these results strongly suggest that oxidative metabolites in addition to TCA are necessary contributors to TCE-induced liver weight changes in mice.

This evaluation focuses primarily on discrete forecasts for the maximum 8-h O sub(3) concentrations covering the 4-month period, June through September, 2007, using measurements obtained from EPA's AIRNow network. Results indicate that the 2007 NAQFC performed as well or better than previous configurations, despite the expansion of the forecast domain into the western half of the nation that is dominated by complex terrain. The mean, domain-wide, season-long correlation was 0.70. When examined over time, the domain-wide correlations exhibit a fairly consistent nature, with values exceeding 0.60 (0.70) over 90% (55%) of the days. The NAQFC systematically over-predicted the 8-h O sub(3) concentrations, continuing a trend established by earlier NAQFC configurations, though to a lesser degree. The summer-long mean forecast value of 53.2ppb was 4.2ppb higher than the observed value, resulting in a domain-wide Normalized Mean Bias (NMB) of 8.7%. Most of the over-prediction is associated with observed concentrations less than 50ppb. In fact the model tends to under-predict when concentrations exceed 70ppb. As with the bias, the error associated with the latest configuration was also lower. The summer-long Root Mean Square Error of 13.0ppb (Normalized Mean Error (NME)=20.4%) represented marked improvements over earlier forecasts. Examination of the spatial distribution of both the NMB and NME reveals that the NAQFC was generally within 25% for the NME and 25% for the NMB over a majority of the domain. Several areas of poorer performance, where the NMB and NME often exceed 25% and in some cases 50%, were noted. These areas include southern California, where the NAQFC tended to under-predict concentrations (especially on weekends) and the southeast Atlantic and Gulf coasts regions, where the model over-predicted. Subsequent analysis revealed that the incorrect temporal allocation of precursor emissions was likely the source of the under-prediction in southern California, while inaccurate simulation of PBL heights likely contributed to the over-prediction in the coastal regions.

Since wood is continually lost from streams, predicting the future input of wood to streams from riparian forests is crucial to assessing or managing stream ecosystems. Unfortunately, regional monitoring protocols have no established capacity to provide this information. The goal of this research is to propose one or more methods that could meet this need. This goal is pursued by using stream wood delivery models to aid in the design of a monitoring method. Two questions are asked. First, does simpler data change model predictions of future contributions of wood from riparian ecosystems to the stream? The answers to this first question enable monitoring design to be tailored to details affecting estimates of future stream condition. These answers are important, because more detailed data is typically more costly. Second, which metrics, if any, correlate well with model predictions? If such metrics can be identified, then these measures can serve as effective indicators of ecosystem function directly, without using ecosystem models. These questions were addressed by collecting highly detailed field observations of riparian forests from 109 forested riparian sites in the Coast Range, Willamette Valley, and western Cascades of northwestern Oregon. Detailed and simplified versions of these data were used in models that forecast the potential of riparian forests to provide wood to the stream. Model predictions with less detailed data typically provided answers different than did predictions made with more detailed data. Thus, ecosystem assessments requiring these types of model predictions would benefit from more detailed data. In contrast, riparian metrics easily observed in the field (e.g. number of basal area of trees) or derived from remotely sensed imagery (e.g. number or height of canopy trees) were well correlated with model predictions of potential stream wood recruitment. When direct model predictions or model scenario analyses are not required, these metrics can serve as effective indicators of the potential of riparian forests to provide wood to the future stream network.

We perform a statistical analysis of 21 years of ozone and temperature observations across the rural eastern U.S. The climate penalty factor is defined as the slope of the ozone/temperature relationship. For two precursor emission regimes, before and after 2002, the climate penalty factor was consistent across the distribution of ozone observations. Prior to 2002, ozone increased by an average of 3.2 ppbv/ degree C. After 2002, power plant NO sub(x) emissions were reduced by 43%, ozone levels fell 10%, and the climate penalty factor dropped to 2.2 ppbv/ degree C. NO sub(x) controls are effective for reducing photochemical smog and might lessen the severity of projected climate change penalties. Air quality models should be evaluated against these observations, and the climate penalty factor metric may be useful for evaluating the response of ozone to climate change.

Polyfluoroalkyl phosphoric acids (PAPs) are fluorinated surfactants used in human food contact paper products. PAPs can migrate into food and food simulants, and their bioavailability and biotransformation into PFCAs has been demonstrated using a rat model. To characterize human exposure to PAP materials, we analyzed pooled human sera samples collected in 2004 and 2005 (n = 10) and 2008 (n = 10) from the midwestern United States for the 4:2 through 10:2 PAP diesters (diPAPs). The 2004 and 2005 sera samples contained 4.5 *mg/L total diPAPs, with the 6:2 diPAP dominating the congener profile at 1.9 c 0.4 *mg/L. DiPAP concentrations observed in the 2004 and 2005 human sera samples were similar to those of the C8 to C11 PFCAs (0.13 c 0.01 to 4.2 c 0.3 *mg/L) monitored in the same samples. 6:2 diPAP was also consistently observed in the 2008 human sera samples at a mean concentration of 0.63 c 0.13 *mg/L. As diPAPs have been shown to degrade to PFCAs in vivo, our observation of diPAPs in human sera may be a direct connection between the legacy of human PFCA contamination and PAPs commercial applications. Wastewater treatment plant (WWTP) sludge and paper fibers were analyzed for diPAPs as a proxy for human use and potential exposure to diPAPs. DiPAPs were observed in WWTP sludge at concentrations ranging from 47 c 22 to 200 c 130 ng/g, a range similar to perfluorooctane sulfonic acid (PFOS) (100 c 70 ng/g) and greater than the C8 to C11 PFCAs (1.6 c 0.6 to 0.17 c 0.10 ng/g) observed in the same samples. DiPAPs were observed in paper fiber extracts at concentrations ranging from 34 c 30 to 2200 c 400 ng/g. The high diPAP concentrations in WWTP sludge suggest PAP materials may be prevalent in our daily lives.

9083248 AB - In utero exposure to linuron, an urea-based herbicide, results in a pattern of malformations of androgen-dependent tissues in adult male rat offspring resembling that produced by some phthalate esters which are known to decrease fetal testosterone production. This study investigated the impact of in utero linuron treatment on fetal testis gene expression and testosterone production. Timed-pregnant Sprague Dawley rats were administered corn oil vehicle, 12.5, 25, 50 or 75mg linuron/day/kg orally from GD13 to 18. Ex vivo testosterone (T) production was significantly decreased at 50 and 75mg/kg when analyzed on a per litter basis. Unlike the phthalate esters, linuron treatment did not affect insl3, cyp17a, cyp11a or StAR mRNA expression. Control GD18 fetal testes were then incubated with increasing concentrations of linuron (1-300 mu M) to evaluate if linuron inhibited T production in vitro. T production was significantly reduced at 30 mu M and above. Progesterone production was not affected in any of the studies indicating that linuron directly inhibited testosterone production in the absence of cytotoxicity. These results indicate the malformations induced by linuron and phthalate esters in male offspring are similar because both reduce fetal T levels during the critical period of sex differentiation but suggest that the mechanisms differ.

Geochemical modeling and solid phase studies. AN - 67053893; 19167132 AB - Arsenic uptake processes were evaluated in a zerovalent iron reactive barrier installed at a lead smelting facility using geochemical modeling, solid-phase analysis, and X-ray absorption spectroscopy techniques. Aqueous speciation of arsenic is expected to play a key role in directing arsenic uptake processes. Geochemical modeling reveals contrasting pH-dependencies for As(III) and As(V) precipitation. At the moderately alkaline pH conditions typically encountered in zerovalent iron reactive barriers, As(III) is unlikely to precipitate as an oxide or a sulfide phase. Conversely, increasing pH is expected to drive precipitation of metal arsenates including ferrous arsenate. Bacterially mediated sulfate reduction plays an important role in field installations of granular iron. Neoformed iron sulfides provide surfaces for adsorption of oxyanion and thioarsenic species of As(III) and As(V) and are expected to provide enhanced arsenic removal capacity. X-ray absorption near edge structure (XANES) spectra indicate that arsenic is sequestered in the solid phase as both As(III) and As(V) in coordination environments with O and S. Arsenic removal in the PRB probably results from several pathways, including adsorption to iron oxide and iron sulfide surfaces, and possible precipitation of ferrous arsenate. Corrosion of granular iron appears to result in some As(III) oxidation to As(V) as the proportion of As(V) to As(III) in the solid phase is greater compared to influent groundwater. As(0) was not detected in the PRB materials. These results are broadly comparable to laboratory based studies of arsenic removal by zerovalent iron, but additional complexity is revealed in the field environment, which is largely due to the influence of subsurface microbiota.

Hydrogeochemical studies. AN - 67051637; 19167133 AB - Developments and improvements of remedial technologies are needed to effectively manage arsenic contamination in groundwater at hazardous waste sites. In June 2005, a 9.1 m long, 14 m deep, and 1.8 to 2.4 m wide (in the direction of groundwater flow) pilot-scale permeable reactive barrier (PRB) was installed at a former lead smelting facility, located near Helena, Montana (USA). The reactive barrier was designed to treat groundwater contaminated with moderately high concentrations of both As(III) and As(V). The reactive barrier was installed over a 3-day period using bio-polymer slurry methods and modified excavating equipment for deep trenching. The reactive medium was composed entirely of granular iron which was selected based on long-term laboratory column experiments. A monitoring network of approximately 40 groundwater sampling points was installed in July 2005. Monitoring results indicate arsenic concentrations >25 mg L(-1) in wells located hydraulically upgradient of the PRB. Of 80 groundwater samples collected from the pilot-PRB, 11 samples exceeded 0.50 mg As L(-1); 62 samples had concentrations of arsenic at or below 0.50 mg L(-1); and, 24 samples were at or below the maximum contaminant level (MCL) for arsenic of 0.01 mg L(-1). After 2 years of operation, monitoring points located within 1 m of the downgradient edge of the PRB showed significant decreases in arsenic concentrations at depth intervals impacted by the emplaced zerovalent iron. This study indicates that zerovalent iron can be effectively used to treat groundwater contaminated with arsenic given appropriate groundwater geochemistry and hydrology. The study also further demonstrates the shortcomings of hanging-wall designs. Detailed subsurface characterization data that capture geochemical and hydrogeologic variability, including a flux-based analysis, are needed for successful applications of PRB technology for arsenic remediation.

To expand their non-native ranges, these invasive taxa must contend with the geographically and ecologically discontinuous nature of estuarine habitats, in many cases without the benefit of highly dispersive larval phases. In addition, their population dynamics may reflect contributions from both sexual and asexual reproduction. Here we use genetic methods to explore the population structure of Nematostella vectensis, a dispersal-limited salt marsh anemone, along the Pacific coast of North America. Analysis of 9 highly polymorphic microsatellite loci reveals that asexual reproduction is critical to both maintenance of local population density and regional population expansion. While high levels of genetic differentiation among populations (F sub(ST) > 0.3) reflect general restrictions to natural dispersal, the observation of 2 clones distributed across multiple, widely separated sampling sites indicates that long distance dispersal of adult anemones is a major contributor to the spread of N. vectensis. We argue that anthropogenic transport represents the most likely mechanism driving this spread, although rafting may offer an alternative explanation for the observed distribution.

AN - 733222766; 19496694 AB - Epidemiology studies have reported associations between increased mortality and morbidity with exposure to particulate air pollution, particularly within individuals with preexisting cardiovascular disease (CVD). Clinical and toxicological studies have provided evidence that exposure to ambient air particulate matter (PM) impacts CVD by increasing plaque size. It is unclear whether PM-induced increased plaque size is associated with molecular disease progression. This study examines molecular profiles within plaques recovered from ApoE(-/-) mice exposed to concentrated ambient air particles (CAPs) to determine whether pulmonary deposition of PM contributes to molecular alterations leading to vascular disease progression. Laser capture microdissection was used to recover atherosclerotic plaques from ApoE(-/-) male mice exposed daily for 5 mo to filtered air or CAPs. Alterations in mRNA expression was assessed in microdissected plaques of CAPs-exposed and air controls using the Affymetrix microarray platform. Bioinformatic analysis indicated alterations in 611 genes: 395 genes downregulated and 216 genes upregulated. Gene ontology revealed CAPs-induced changes to inflammation, proliferation, cell cycle, hematological system, and cardiovascular pathways. Quantitative reverse-transcription polymerase chain reaction (qRT-PCR) verified microarray data also revealing gene expression alterations undetected by the microarray analysis, i.e., decreased expression of alpha-actin for smooth muscle cells, and increased expression of the macrophage marker Cd68 and of beta-actin. Comparison of CAPs-induced gene expression profiles demonstrated consistency with previously published gene expression profiles in the ApoE(-/-) mouse model and humans associated with plaque progression. These results indicate that exposure to fine PM induces molecular alterations associated with vascular disease progression and provides insight into potential biological pathways responsible for this effect.

AN - 67614659; 19714882 AB - Propiconazole, a widely used fungicide, is hepatotoxic and hepatotumorigenic in mice. Previous genomic analysis of liver tissues from propiconazole-treated mice identified genes and pathways involved in oxidative stress, suggesting that oxidative stress may play a role in propiconazole-induced toxicity. To understand the contribution of oxidative stress on toxicity at the protein level, we developed an integrated approach for the systematic measurement of protein oxidation in the livers from propiconazole-treated mice. Liver protein carbonylation increased significantly after treatment with propiconazole, demonstrating propiconazole-associated induction of oxidative stress. Utilizing two-dimensional gel electrophoresis (2-DE), immunoblotting, and mass spectrometry, we identified 17 carbonylated proteins that were altered with varying intensities by propiconazole treatment. The potential effects of protein carbonylation on protein functions and cellular activities in the liver of propiconazole-treated mice were further investigated. A significant negative correlation between protein carbonylation and cytochrome c reductase activity was found. We conclude that glycolysis, mitochondrial respiratory chain, ATP production, amino acid metabolism, CO2 hydration, cellular antioxidant defense and detoxification system, and tetrahydrobiopterin pathways are affected by oxygen radicals in the livers of propiconazole-treated mice. This study suggests a mode of propiconazole-induced toxicity in mouse liver which primarily involves oxidative damage to cellular proteins.

AN - 67252739; 19452883 AB - The fate of organophosphorus (OP) pesticides in the presence of aqueous chlorine was investigated under simulated drinking water treatment conditions. Intrinsic rate coefficients were found for the reaction of hypochlorous acid (k(HOCl,OP)) and hypochlorite ion (k(OCl,OP) for several OP pesticides. The reaction of hypochlorous acid (HOCl) with each OP pesticide was relatively rapid near neutral pH, k(HOCl,OP) = 0.86 - 3.56 x 10(6) M(-1)h(-1). HOCI reacts at the thiophosphate (P = S) moiety of the OP pesticide resulting in the formation of the corresponding oxon (P=0), which is more toxic than the parent pesticide. Hypochlorite ion (OCl-) was found not to oxidize OP pesticides but act like a nucleophile accelerating hydrolysis, k(OCl,OP) = 37.3-15910 M(-1)h(-1). Both the k(HOCl,OP) and the k(OCl,OP) were found to correlate well with molecular descriptors within each subgroup of the OP pesticide class. A model was developed to predict the transformation of OP pesticides in the presence of aqueous chlorine. With hydrolysis rate coefficients, the transformation of OP pesticides under drinking water treatment conditions was found to be adequately predicted. The structure-activity relationships and model developed here could be used by risk assessors to determine exposure to OP pesticides and their transformation products in potable water.

AN - 67225560; 19440503 AB - Several chemicals in the environment have the potential to inhibit aromatase, an enzyme critical to estrogen synthesis. The objective of this study was to provide a detailed characterization of molecular and biochemical responses of female fathead minnows to a model aromatase inhibitor, fadrozole (FAD). Fish were exposed via water to 0, 3, or 30 microg FAD/L for 8 days and then held in clean water for 8 days, with samples collected at four time points during each 8-day period. We quantified ex vivo steroid production, plasma steroids, and plasma vitellogenin (Vtg) concentrations and analyzed relative transcript abundance of 10 key regulatory genes in ovaries and 3 in pituitary tissue by real-time polymerase chain reaction. Ex vivo 17beta-estradiol (E2) production and plasma E2 and Vtg concentrations were significantly reduced after a single day of exposure to 3 microg or 30 microg FAD/L. However, plasma E2 concentrations recovered by the eighth day of exposure in the 3-microg/L group and within 1 day of cessation of exposure in the 30-microg/L group, indicating concentration- and time-dependent physiologic compensation and recovery. Concentration-dependent increases in transcripts coding for aromatase (A isoform), cytochrome P450 side-chain cleavage, steroidogenic acute regulatory protein, and follicle-stimulating hormone receptor all coincided with increased E2 production and recovery of plasma E2 concentrations. Results of this research highlight the need to consider compensation/adaptation and recovery when developing and interpreting short-term bioassays or biomarkers or when trying to predict the effects of chemical exposures based on mode of action.

AN - 67202834; 19418820 AB - Population-based human exposure models predict the distribution of personal exposures to pollutants of outdoor origin using a variety of inputs, including air pollution concentrations; human activity patterns, such as the amount of time spent outdoors versus indoors, commuting, walking, and indoors at home; microenvironmental infiltration rates; and pollutant removal rates in indoor environments. Typically, exposure models rely upon ambient air concentration inputs from a sparse network of monitoring stations. Here we present a unique methodology for combining multiple types of air quality models (the Community Multi-Scale Air Quality [CMAQ] chemical transport model added to the AERMOD dispersion model) and linking the resulting hourly concentrations to population exposure models (the Hazardous Air Pollutant Exposure Model [HAPEM] or the Stochastic Human Exposure and Dose Simulation [SHEDS] model) to enhance estimates of air pollution exposures that vary temporally (annual and seasonal) and spatially (at census-block-group resolution) in an urban area. The results indicate that there is a strong spatial gradient in the predicted mean exposure concentrations near roadways and industrial facilities that can vary by almost a factor of 2 across the urban area studied. At the high end of the exposure distribution (95th percentile), exposures are higher in the central district than in the suburbs. This is mostly due to the importance of personal mobility factors whereby individuals living in the central area often move between microenvironments with high concentrations, as opposed to individuals residing at the outskirts of the city. Also, our results indicate 20-30% differences due to commuting patterns and almost a factor of 2 difference because of near-roadway effects. These differences are smaller for the median exposures, indicating the highly variable nature of the reflected ambient concentrations. In conjunction with local data on emission sources, microenvironmental factors, and behavioral and socioeconomic characteristics, the combined source-to-exposure modeling methodology presented in this paper can improve the assessment of exposures in future community air pollution health studies.

AN - 67162560; 19391686 AB - Management strategies for controlling anthropogenic mercury emissions require understanding how ecosystems will respond to changes in atmospheric mercury deposition. Process-based mathematical models are valuable tools for informing such decisions, because measurement data often are sparse and cannot be extrapolated to investigate the environmental impacts of different policy options. Here, we bring together previously developed and evaluated modeling frameworks for watersheds, water bodies, and food web bioaccumulation of mercury. We use these models to investigate the timescales required for mercury levels in predatory fish to change in response to altered mercury inputs. We model declines in water, sediment, and fish mercury concentrations across five ecosystems spanning a range of physical and biological conditions, including a farm pond, a seepage lake, a stratified lake, a drainage lake, and a coastal plain river. Results illustrate that temporal lags are longest for watershed-dominated systems (like the coastal plain river) and shortest for shallow water bodies (like the seepage lake) that receive most of their mercury from deposition directly to the water surface. All ecosystems showed responses in two phases: A relatively rapid initial decline in mercury concentrations (20-60% of steady-state values) over one to three decades, followed by a slower descent lasting for decades to centuries. Response times are variable across ecosystem types and are highly affected by sediment burial rates and active layer depths in systems not dominated by watershed inputs. Additional research concerning watershed processes driving mercury dynamics and empirical data regarding sediment dynamics in freshwater bodies are critical for improving the predictive capability of process-based mercury models used to inform regulatory decisions.

AN - 67086609; 19126624 AB - In tungsten refining and manufacturing processes, a series of tungsten oxides are typically formed as intermediates in the production of tungsten powder. The present study was conducted to characterize airborne tungsten-containing fiber dimensions, elemental composition and concentrations in the US tungsten refining and manufacturing industry. During the course of normal employee work activities, seven personal breathing zone and 62 area air samples were collected and analyzed using National Institute for Occupational Safety and Health (NIOSH) fiber sampling and counting methods to determine dimensions, composition and airborne concentrations of fibers. Mixed models were used to identify relationships between potential determinants and airborne fiber concentrations. Results from transmission electron microscopy analyses indicated that airborne fibers with length >0.5 microm, diameter >0.01 microm and aspect ratios > or =3:1 were present on 35 of the 69 air samples collected. Overall, the airborne fibers detected had a geometric mean length approximately 3 microm and diameter approximately 0.3 microm. Ninety-seven percent of the airborne fibers identified were in the thoracic fraction (i.e. aerodynamic diameter 5 microm, diameter or = 5:1), airborne fiber concentrations ranged from below the limit of detection to 0.085 fibers cm(-3), with calcining being associated with the highest airborne concentrations. The mixed model procedure indicated that process temperature had a marginally significant relationship to airborne fiber concentration. This finding was expected since heated processes such as calcining created the highest airborne fiber concentrations. The finding of airborne tungsten-containing fibers in this occupational setting needs to be confirmed in similar settings and demonstrates the need to obtain information on the durability and associated health effects of these fibers.

AN - 67028413; 18850244 AB - The Hydrogeomorphic (HGM) functional assessment method is predicated on the ability of hydrogeomorphic wetland classification and visual assessment of alteration to provide reference standards against which functions in individual wetlands can be evaluated. The effectiveness of this approach was tested by measuring nitrogen cycling functions in forested wetlands in an urbanized region in New Jersey, USA. Fourteen sites represented three HGM classes and were characterized as "least disturbed reference" or "non-reference" based on initial visual assessment. Water table levels and in situ rates of net nitrogen mineralization, net nitrification, and denitrification were measured over one year in each site. Hydrological alterations, resulting in consistently low or flashy water table levels, were not correlated with a priori designations as reference and non-reference. Although the flat-riverine wetland class had lower net nitrification and higher denitrification rates than riverine or mineral flat wetland classes, this difference was attributable to the lack of hydrologically-altered wetlands in the flat-riverine class, and thus more consistently wet conditions. Within all HGM classes, a classification based on the long-term hydrological record that separated sites with "normal," saturated hydrology from those with "altered," drier hydrology, clearly distinguished sites with different nitrogen cycling function. Based on these findings, current practices for designating reference standard sites to judge wetland functions, at least in urbanized regions, are ineffective and potentially misleading. At least one year of hydrological monitoring data is suggested to classify wetlands into groups that have different nutrient cycling functions, particularly in urban landscapes.

AN - 66999513; 19081631 AB - The occurrence of trace levels of prescription and over-the-counter pharmaceuticals in the environment began to receive concerted attention nearly two decades ago. The public's growing awareness and concern over the presence of these chemicals, especially in drinking water, has served to catalyze considerable discussion and debate regarding the best practices for disposal of unused or unwanted medications. In the United States, the first federal guidance for consumers was issued in 2007. It recommends discarding unused pharmaceuticals to household trash, after taking precautions to mix the pharmaceuticals with an inert substance and conceal the contents from view. Providing the consumer with additional options for conscientious disposal are various community, city, and state collection events, ongoing programs, and government-funded pilot projects. These strategies include the opportunity to mail or bring unused medications to various collection points, such as pharmacies, for eventual destruction. All of these approaches to medication disposal play roles in reducing the introduction of pharmaceuticals to the environment.

AN - 66943654; 19150735 AB - Bioaccumulation of endocrine disruptors in marine mammals positioned at the top of the food chain is of toxicological concern. Livers from four pups and ten adult harbor seals (Phoca vitulina) stranded in San Francisco Bay (SFB) and the Gulf of Maine (GOM) were analyzed for polychlorinated biphenyls (PCBs) and their hydroxylated metabolites (OH-PCBs). We used GC-ECD and GC-NCI/MS to investigate the presence of 28 PCBs and 8 OH-PCB metabolites, respectively. Sigma(28)PCB concentrations (di- to octa-CBs) ranged from 1.81 to 35.9 microg/g lipid with a median of 6.53 for the seal pups and 2.31 to 249 microg/g lipid with a median of 28.9 for the adult seals. Sigma(8)OH-PCB concentrations (penta- to hepta-OH-PCBs) ranged from 0.02 to 0.69 microg/g lipid with a median of 0.04 for the adult seals, i.e., at much lower concentrations than those for PCBs. Ratios of OH-PCBs to PCBs (0.24% on average) were comparable to those in beluga whale, but were lower than ratios in human livers. The OH-PCB profiles were slightly different between SFB and GOM seal livers, although similar PCB congener patterns were observed. Generally, 4-OH-CB107 was found predominantly in seal livers and was the only OH-PCB detectable in most of seal pup livers. This study provides information on OH-PCBs in seals, adding to the scarce exposure data for these chemicals.

As a result, the sediments themselves can become a source of contamination. At sufficient levels, contaminated sediments can cause benthic impairments and toxicity to marine organisms. Among the wide range of contaminants, nonionic organic contaminants (NOCs) are a primary cause of toxicity in marine sediments. Toxicity identification evaluations (TIEs) are used to characterize and identify chemicals causing toxicity in effluents, interstitial waters, and whole sediments using whole-organism endpoints. Phase I whole-sediment TIE methods for NOCs exist, but the development of phase II TIE methods for NOCs is a current research challenge. In the present study, the use of reverse polyethylene samplers (RePES) for phase II methods is examined. Various RePES designs were evaluated in an experimental design study with NOC chemical solutions. Based on equilibration time and proximity of measured NOC water concentrations in the reconstituted system to theoretical concentrations, a nontriolein design with loading of chemical solutions on the inside of the polyethylene tubing was chosen as most effective. A partitioning study demonstrated NOCs partitioned between the RePES and water as well as between the water and air, as expected using this nontriolein RePES design. Finally, a sediment toxicity study comparing the nontriolein RePES to contaminant-spiked sediments was conducted. The nontriolein RePES design was capable of successfully recreating the toxicity and water concentrations observed with the intact sediments.

In this study, an inexpensive electropositive cartridge filter, the NanoCeram filter, was evaluated for its ability to concentrate enteroviruses and noroviruses from large volumes of water. Seeded viruses were concentrated using the adsorption-elution procedure. The mean percent retention of seeded polioviruses by NanoCeram filters was 84%. To optimize the elution procedure, six protocols, each comprising two successive elutions with various lengths of filter immersion, were evaluated. The highest virus recovery (77%) was obtained by immersing the filters in beef extract for 1 minute during the first elution and for 15 min during the second elution. The recovery efficiencies of poliovirus, coxsackievirus B5, and echovirus 7 from 100-liter samples of seeded tap water were 54%, 27%, and 32%, respectively. There was no significant difference in virus recovery from tap water with a pH range of 6 to 9.5 and a water flow rate range of 5.5 liters/min to 20 liters/min. Finally, poliovirus and Norwalk virus recoveries by NanoCeram filters were compared to those by 1MDS filters, using tap water and Ohio River water. Poliovirus and Norwalk virus recoveries by NanoCeram filters from tap and river water were similar to or higher than those by the 1MDS filters. These data suggest that NanoCeram filters can be used as an inexpensive alternative to 1MDS filters for routine viral monitoring of water.

Solar radiation dosimetry within multiple coral reef areas of South Florida was assessed using remote sensed, modeled, and measured values during a minor bleaching event during August 2005. Coral reefs in the Dry Tortugas and Upper Keys had similar diffuse downwelling attenuation coefficients (Kd, m super(-1)), whereas Kd values were significantly greater in the Middle and Lower Keys. Mean 1% attenuation depths varied by reef region for ultraviolet B (UVB; 9.7 to 20m), ultraviolet A (UVA; 22 to 40m) and visible (27 to 43m) solar radiation. Solar irradiances determined from remote sensed data were significantly correlated with measured values, but were generally overestimated at the depth of corals. Solar irradiances modeled using an atmospheric radiative transfer model parameterized with site specific approximations of cloud cover showed close agreement with measured values. Estimated daily doses (W h/m super(2)) of UVB (0.01-19), UVA (2-360) and visible (29-1,653) solar radiation varied with coral depth (2 to 24m) and meteorological conditions. These results indicate large variation in solar radiation dosimetry within coral reefs that may be estimated with reasonable accuracy using regional Kd measurements and radiative transfer modeling.

Established testing methods and the short life cycle of the sheepshead minnow, Cyprinodon variegatus, make this species particularly suitable for use in identifying potential impacts of contaminants in estuarine and marine environments. This study describes the refinement of life-cycle exposure methods that increased the reliability of reproduction in sheepshead minnows and reduced the time to maturation for larvae and juvenile fishes. A test of three spawning chamber designs, three sex ratios, and two photoperiods identified conditions that reduced the coefficient of variation in egg production from>100% to as little as 32%. The most reliable results were produced with groups of three female and two male fishes (all of similar size) when they were placed in a rectangular chamber and acclimated for 12days. A test water temperature of 26.5c2C and a 14L:10D photoperiod resulted in fish producing a mean of 74 embryos per female per day, with a coefficient of variation of 31.8%. Egg fertility exceeded 90%, with a hatch rate of 95% for normal embryos (.80% yolk) and a hatch rate of,45% for embryos containing,77% yolk. The length of time to grow larvae to spawning adult fish was reduced to~60days posthatch by feeding them flake food twice daily to satiation for 15min, and it was observed that size (.2.7cm standard length) was critical for spawning readiness. Adult fish were prepared for the spawning assessment by adding frozen brine shrimp to their diet.

The purpose of the on-site survey was to help the National Park Service better understand the visitors of GSD; it was not intended for a travel cost model. Variables such as travel cost and income were estimated based on respondents' Zip Codes. Following approaches found in the literature, a negative binomial model corrected for truncation and endogenous stratification fit the data the best. We estimate a recreational benefit of U.S. $89/visitor/year or U.S. $54/visitor/24-h recreational day (in 2002 U.S. $). Based on the approach presented here, there are other data sets for national parks, preserves, and battlefields where travel cost models could be estimated and used to support National Park Service management decisions.

We present results that suggest a trade-off between nest crypticity and thermoregulation of eggs based on selection of nest materials by piping plovers (Charadrius melodus), a ground-nesting bird that constructs simple, pebble-lined nests highly vulnerable to predators and exposed to temperature extremes. Piping plovers selected pebbles that were whiter and appeared closer in color to eggs than randomly available pebbles, suggesting a crypsis function. However, nests that were more contrasting in color to surrounding substrates were at greater risk of predation, suggesting an alternate strategy driving selection of white rocks. Near-infrared reflectance of nest pebbles was higher than randomly available pebbles, indicating a direct physical mechanism for heat control through pebble selection. Artificial nests constructed of randomly available pebbles heated more quickly and conferred heat to model eggs, causing eggs to heat more rapidly than in nests constructed from piping plover nest pebbles. Thermal models and field data indicated that temperatures inside nests may remain up to 2-6C cooler than surrounding substrates. Thermal models indicated that nests heat especially rapidly if not incubated, suggesting that nest construction behavior may serve to keep eggs cooler during the unattended laying period. Thus, pebble selection suggests a potential trade-off between maximizing heat reflectance to improve egg microclimate and minimizing conspicuous contrast of nests with the surrounding substrate to conceal eggs from predators. Nest construction behavior that employs light-colored, thermally reflective materials may represent an evolutionary response by birds and other egg-laying organisms to egg predation and heat stress.

In every test, the results of each operator have been compared with the scores of a group of experts. For quality evaluation, we have used accuracy and precision to define the percentage error for identification of taxa and counts of pollen grains. Cohen's K has been estimated for the analysis of reliability. This work suggests a method to set up an intercalibration test for airborne pollen monitoring and to introduce the suitableness of measurement quality objectives (MQOs). The results show the important role of operators' training and the need for standards in pollen monitoring quality evaluation.

We examined the nitrogen sources to Yaquina Estuary (Oregon, USA) as well as the relationships between physical forcing and gross oceanic input of nutrients and phytoplankton. The ocean is the dominant source of dissolved inorganic nitrogen (DIN) and phosphate to the lower portion of Yaquina Bay during the dry season (May through October). During this time interval, high levels of dissolved inorganic nitrogen (primarily in the form of nitrate) and phosphate entering the estuary lag upwelling favorable winds by 2 days. The nitrate and phosphate levels entering the bay associated with coastal upwelling are correlated with the wind stress integrated over times scales of 4-6 days. In addition, there is a significant import of chlorophyll a to the bay from the coastal ocean region, particularly during July and August. Variations in flood-tide chlorophyll a lag upwelling favorable winds by 6 days, suggesting that it takes this amount of time for phytoplankton to utilize the recently upwelled nitrogen and be transported across the shelf into the estuary. Variations in water properties determined by ocean conditions propagate approximately 11-13 km into the estuary. Comparison of nitrogen sources to Yaquina Bay shows that the ocean is the dominant source during the dry season (May to October) and the river is the dominant source during the wet season with watershed nitrogen inputs primarily associated with nitrogen fixation on forest lands.

The contactor was successfully acclimated with indigenous microorganisms. Influent temperatures varied from 1.4 to 30 super(o)C. The objectives of the study were to investigate the effects of temperature on perchlorate removal, nitrate removal, nitrite formation, dissolved oxygen consumption, sulfide production, and nutrient acetate consumption. The results confirmed that consistent biological perchlorate removal to 2kg/L is feasible at temperatures above 10 super(o)C. Effluent concentrations of perchlorate, nitrate, and dissolved oxygen varied inversely with temperature, while sulfide varied positively with temperature. Under the conditions that prevailed during this study, 10 super(o)C was a threshold temperature below which microbial activity, including perchlorate reduction, decreased dramatically.

However, direct estimation of seasonal fecundity is difficult, especially with multi-brooded birds, and models representing the renesting and quitting processes are usually required. To explore the consequences of modeling decisions on inference about avian seasonal fecundity, we generalize previous Markov chain (MC) models of avian nest success to formulate two different MC models of avian seasonal fecundity that represent two different ways to model renesting decisions and breeding cessation. We parameterize both Markov chains (regular and absorbing) for two species (Eastern Meadowlark, Sturnella magna, and Dickcissel, Spiza americana) and compare the results using mean-square error of the estimated number of successful broods per breeding female. We also provide formulae for estimating the expected variation in female breeding success. The absorbing MC performed better for both species, although the regular MC performed almost as well when the duration of the breeding season was estimated by taking the 95th percentile of a negative binomial distribution fit to the observed durations among all females. In their simplest form the models contain very few parameters (four or five) and should also prove useful as a foundation for more complex models of avian seasonal fecundity and demography.

A chemically-activated luciferase gene expression cell bioassay system (CALUX) and an antibody-based method enzyme immunoassay (EIA) were used to detect the dioxin-like response of several polybrominated, polychlorinated, and polybrominated/chlorinated dibenzo-p-dioxins/furans (PBDDs/Fs, PCDDs/Fs, and PBCDDs/Fs, respectively). It has been suggested that the biological activity of the brominated and mixed bromo/chloro compounds is similar to their chlorinated analogues (measured by binding to the Ah receptor). PBDD/F, PCDD/F, and PBCDD/F laboratory standards exhibited biological activity ranging over three orders of magnitude. The highest relative potency (REP) values from CALUX analysis, when compared to 2,3,7,8-TCDD, were 2,3,7,8-TBDD at 0.99 (+/-0.07), 1,2,3,7,8-PeCDD at 0.69, and 2-Br-3,7,8-TriCDD at 0.72 (+/-0.02). Cross-reactivities were calculated using EIA for several PBDDs/Fs and PBCDDs. The highest percent cross-reactivity was found for 2,3,7,8-TBDD at 138 (+/-34%), and 2,3,7-TriBDD at 84 (+/-36%).

LRBS (super *) is the log of the ratio of bed surface geometric mean particle diameter (D (sub gm) ) to critical diameter (D (super *) (sub cbf) ) at bankfull flow, based on a modified Shield's criterion for incipient motion. We used a formulation of LRBS (super *) that explicitly accounts for reductions in bed shear stress that result from channel form roughness due to pools and wood. LRBS (super *) ranged from -1.9 to +0.5 in streams within the lower quartile of human riparian and basin disturbance, and was substantially lower (-4.2 to -1.1) in streams within the upper quartile of human disturbance. Modeling results suggest that the expected range of LRBS (super *) in streams without human disturbances in this region might be generally between -0.7 and +0.5 in either sedimentary or volcanic lithology. However, streams draining relatively soft, erodible sedimentary lithology showed greater reductions in LRBS (super *) associated with disturbance than did those having harder, more resistant volcanic (basalt) lithology with similar levels of basin and riparian disturbance. At any given level of disturbance, smaller streams had lower LRBS (super *) than those with larger drainages. In sedimentary lithology (sandstone and siltstone), high-gradient streams had higher LRBS (super *) than did low-gradient streams of the same size and level of human disturbance. High gradient streams in volcanic lithology, in contrast, had lower LRBS (super *) than low-gradient streams of similar size and disturbance. Correlations between D (sub gm) and land disturbance were stronger than those observed between D (super *) (sub cbf) and land disturbance. This pattern suggests that land use has augmented sediment supplies and increased streambed fine sediments in the most disturbed streams. However, we also show evidence that some of the apparent reductions in LRBS (super *) , particularly in steep streams draining small volcanic drainages, may have resulted in part from anthropogenic increases in bed shear stress. The synoptic survey methods and designs we use appear adequate to evaluate regional patterns in bed stability and sedimentation and their general relationship to human disturbances. More precise field measurements of channel slope, cross-section geometry, and bed surface particle size would be required to use LRBS (super *) in applications requiring a higher degree of accuracy and precision, such as site-specific assessments at individual streams.

Animals were introduced into defaunated sediment and allowed to burrow for four months at mildly hypoxic (2 mg l super(-) super(1)) and normoxic (7 mg l super(-) super(1)) dissolved oxygen (DO) levels. Sediment redox profiles were measured 10 times during the course of the experiment. At the end of the experiment, the sediment was imaged using computer-aided tomography to quantify burrow volume and location. For the three species, burrow volume remained constant over DO treatments, but amphipod and clam burrows were shallower in hypoxic treatments compared with normoxic treatments. Redox profile discontinuity (RPD) depth was shallower in hypoxic treatments compared with normoxic treatments for experiments without animals, indicating that water column oxygen concentration alone influences diffusion of oxygen into the sediment. Worms, but neither clams nor amphipods, increased the RPD depth relative to no-animal controls in both hypoxic and normoxic treatments, but the effect was greater in normoxic conditions. These results suggest that although hypoxia can reduce burrowing depth, infauna can still increase the depth to which oxygen penetrates the sediment, but not to the same degree as they would under normoxic conditions.

Gas chromatography/mass spectrometry was used to confirm numerous airborne contaminants obtained from the analysis of semipermeable membrane devices deployed inside of 52 homes situated along the border between Arizona and Mexico. We also describe nontarget analytes in the organochlorine pesticide fractions of 12 of these homes; this fraction is also the most likely to contain the broadest scope of bioconcentratable chemicals accumulated from the indoor air. Approximately 400 individual components were identified, ranging from pesticides to a wide array of hydrocarbons, fragrances such as the musk xylenes, flavors relating to spices, aldehydes, alcohols, esters and phthalate esters, and other miscellaneous types of chemicals. The results presented in this study demonstrate unequivocally that the mixture of airborne chemicals present indoors is far more complex than previously demonstrated.

AN - 67048205; 19292459 AB - Analysis of an individual's total daily food intake may be used to determine aggregate dietary ingestion of given compounds. However, the resulting composite sample represents a complex mixture, and measurement of such can often prove to be difficult. In this work, an analytical scheme was developed for the determination of 12 select pyrethroid pesticides in dietary samples. In the first phase of the study, several cleanup steps were investigated for their effectiveness in removing interferences in samples with a range of fat content (1-10%). Food samples were homogenized in the laboratory, and preparatory techniques were evaluated through recoveries from fortified samples. The selected final procedure consisted of a lyophilization step prior to sample extraction. A sequential 2-fold cleanup procedure of the extract included diatomaceous earth for removal of lipid components followed with a combination of deactivated alumina and C(18) for the simultaneous removal of polar and nonpolar interferences. Recoveries from fortified composite diet samples (10 microg kg(-1)) ranged from 50.2 to 147%. In the second phase of this work, three instrumental techniques [gas chromatography-microelectron capture detection (GC-microECD), GC-quadrupole mass spectrometry (GC-quadrupole-MS), and GC-ion trap-MS/MS] were compared for greatest sensitivity. GC-quadrupole-MS operated in selective ion monitoring (SIM) mode proved to be most sensitive, yielding method detection limits of approximately 1 microg kg(-1). The developed extraction/instrumental scheme was applied to samples collected in an exposure measurement field study. The samples were fortified and analyte recoveries were acceptable (75.9-125%); however, compounds coextracted from the food matrix prevented quantitation of four of the pyrethroid analytes in two of the samples considered.

AN - 67143657; 19368200 AB - A 30-month performance evaluation of a pilot permeable reactive barrier (PRB) consisting of a mixture of leaf compost, zerovalent iron (ZVI), limestone, and pea gravel was conducted at a former phosphate fertilizer manufacturing facility in Charleston, SC. The PRB is designed to remove heavy metals and arsenic from groundwater by promoting microbially mediated sulfate reduction and sulfide-mineral precipitation and arsenic and heavy metal sorption. Performance monitoring showed effective treatment of As, Pb, Cd, Zn, and Ni from concentrations as high as 206 mg L(-1), 2.02 mg L(-1), 0.324 mg L(-1), 1060 mg L(-1), and 2.12 mg L(-1), respectively, entering the PRB, to average concentrations of <0.03 mg L(-1), < 0.003 mg L(-1), < 0.001 mg L(-1), < 0.23 mg L(-1), and <0.003 mg L(-1), respectively, within the PRB. Both As(III) and As(V) were effectively removed from solution with X-ray absorption near edge structure (XANES) analysis of core samples indicating the presence of As(V) in oxygen-bound form and As(III) in both oxygen- and sulfur-bound forms. XANES solid phase sulfur analysis indicated decreases in the peak amplitude of intermediate oxidized sulfur species and sulfate components with increasing distance and depth within the PRB.

AN - 67139270; 19368161 AB - The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE) projects represents roughly 14% of U.S. nonhydro renewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity generated for these energy recovery options. In addition, sensitivity analysis is conducted on key inputs (e.g., efficiency of the WTE plant landfill gas management schedules, oxidation rate, and waste composition) to quantify the variability in the resultant life-cycle emissions estimates. While methane from landfills results from the anaerobic breakdown of biogenic materials, the energy derived from WTE results from the combustion of both biogenic and fossil materials. The greenhouse gas emissions for WTE ranges from 0.4 to 1.5 MTCO2e/MWh, whereas the most agressive LFGTE scenerio results in 2.3 MTCO2e/MWh. WTE also produces lower NO(x) emissions than LFGTE, whereas SO(x) emissions depend on the specific configurations of WTE and LFGTE.

14898825 AB - This article describes a statistical analysis of small water systems' turbidity data within the framework of a logic model for the USEPA's Performance-Based Training (PBT) program. The logic model shows the theoretical linkages between optimization training for small system operators; operator application of optimization techniques; improvements in plant filtration performance; and public health protection. The analysis comprised two phases. For the first phase, the authors used Bayesian analysis of turbidity data to test the statistical significance of changes in finished water quality resulting from training for small water system operators. For the second phase, the authors estimated the potential health benefits resulting from measured improvements in filtration performance. Considering only the improved removal of the pathogen Cryptosporidium, the expected annual health benefit of PBT is about ten fewer cases of infection per thousand persons served (within a 95% credible interval 0 to 18 fewer infections), though there may be benefits associated with the removal of other pathogens. The article also describes factors contributing to uncertainty in the estimated potential health benefits. The proposed two-phase approach supports the USEPA's development of drinking water program indicators which are meaningful, measurable, broadly applicable and change-sensitive.

The model was validated using data from a high-dose experiment in humans where doses and resulting concentrations of perchlorate in blood and urine were well documented. Specifically, data were available for individuals who had been dosed at 0.5, 0.1, and 0.02mg/kg/day for 14 consecutive days, significantly higher than the average background dose, which is estimated to be less than 0.0001mg/kg/day. The average measured urine concentration in the high-dose regime during the experiment was 15.4mg/l compared with an average prediction of 17.3mg/l. In the medium-dose regime, the average measured was 3.0mg/l compared with 4.1mg/l predicted, and in the low-dose regime, the average measured was 0.53mg/l compared with 0.68mg/l predicted. For blood, the analogous results include 0.51mg/l measured compared with 0.54mg/l predicted in the high-dose regime and 0.12mg/l measured versus 0.11mg/l predicted in the medium-dose regime. The model was then used to study background exposures to perchlorate. A national sampling of perchlorate in urine showed a median concentration of 0.0035mg/l, and this was used to back-calculate a dose of 0.000064mg/kg/day. This finding was independently verified with the modeling structure of this study, as use of that back-calculated dose of 0.000064mg/kg/day resulted in predictions of urine concentration with an average virtually identical at 0.0033mg/l. An examination of literature data on the possible pathways of exposure suggests that the consumption of foods, rather than ingestion of water, dominates background exposures. Daily variation in urine concentration was studied with the model, and it was found that concentrations in the morning hours were lower than concentrations in the afternoon and evening hours, corresponding to the time when most exposure was assumed to occur.Journal of Exposure Science and Environmental Epidemiology (2009) 19, 260-273; doi:10.1038/jes.2008.8; published online 16 April 2008 JF - Journal of Exposure Science and Environmental Epidemiology AU - Lorber, Matthew AD - aOffice of Research and Development, United States Environmental Protection Agency, 1200 Pennsylvania Ave, Washington, District of Columbia 20460, USA Y1 - 2009/03// PY - 2009 DA - Mar 2009 SP - 260 EP - 273 PB - Nature Publishing Group, The Macmillan Building London N1 9XW UK VL - 19 IS - 3 SN - 1559-0631, 1559-0631 KW - Toxicology Abstracts KW - Data processing KW - Ingestion KW - perchlorate KW - Pharmacokinetics KW - Models KW - Blood KW - Food consumption KW - Epidemiology KW - Urine KW - Perchloric acid KW - Sampling KW - Internet KW - X 24300:Methods UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/754883712?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Atoxicologyabstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.atitle=Use+of+a+simple+pharmacokinetic+model+to+characterize+exposure+to+perchlorate&rft.au=Lorber%2C+Matthew&rft.aulast=Lorber&rft.aufirst=Matthew&rft.date=2009-03-01&rft.volume=19&rft.issue=3&rft.spage=260&rft.isbn=&rft.btitle=&rft.title=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.issn=15590631&rft_id=info:doi/10.1038%2Fjes.2008.8 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2010-09-01 N1 - Last updated - 2015-03-31 N1 - SubjectsTermNotLitGenreText - Food consumption; Blood; Data processing; Epidemiology; Urine; Sampling; Perchloric acid; Internet; Pharmacokinetics; Models; Ingestion; perchlorate DO - http://dx.doi.org/10.1038/jes.2008.8 ER - TY - JOUR T1 - 4.7 Biological modeling as a method for data evaluation and integration in toxicology AN - 744582252; 12614151 JF - Human & Experimental Toxicology AU - Barton, HA AD - National Center for Computational Toxicology, Office of Research and Development, United States Environmental Protection Agency, Research Triangle Park, North Carolina, USA, habarton@alum.mit.edu Y1 - 2009/03// PY - 2009 DA - Mar 2009 SP - 143 EP - 145 PB - Sage Publications Ltd., 6 Bonhill St. London EC2A 4PU UK VL - 28 IS - 2-3 SN - 0960-3271, 0960-3271 KW - Toxicology Abstracts KW - Integration KW - Data processing KW - X 24300:Methods UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/744582252?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Atoxicologyabstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Human+%26+Experimental+Toxicology&rft.atitle=4.7+Biological+modeling+as+a+method+for+data+evaluation+and+integration+in+toxicology&rft.au=Barton%2C+HA&rft.aulast=Barton&rft.aufirst=HA&rft.date=2009-03-01&rft.volume=28&rft.issue=2-3&rft.spage=143&rft.isbn=&rft.btitle=&rft.title=Human+%26+Experimental+Toxicology&rft.issn=09603271&rft_id=info:doi/10.1177%2F0960327109105774 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2010-05-01 N1 - Last updated - 2012-03-29 N1 - SubjectsTermNotLitGenreText - Integration; Data processing DO - http://dx.doi.org/10.1177/0960327109105774 ER - TY - JOUR T1 - A nonlethal microsampling technique to monitor the effects of mercury on wild bird eggs. AN - 67177843; 18937540 AB - Methylmercury is the predominant chemical form of mercury reported in the eggs of wild birds, and the embryo is the most sensitive life stage to methylmercury toxicity. Protective guidelines have been based mainly on captive-breeding studies with chickens (Gallus gallus), mallards (Anas platyrhynchos), and ring-necked pheasants (Phasianus colchicus) or on field studies where whole eggs were collected and analyzed and the effects of the mercury were measured based on the reproductive success of the remaining eggs. However, both of these methods have limitations. As an alternative, we developed a technique that involves extracting a small sample of albumen from a live egg, sealing the egg, returning the egg to its nest to be naturally incubated by the parents, and then relating the hatching success of this microsampled egg to its mercury concentration. After first developing this technique in the laboratory using chicken and mallard eggs, we selected the laughing gull (Larus atricilla) and black-necked stilt (Himantopus mexicanus) as test subjects in the field. We found that 92% of the microsampled laughing gull eggs met our reproductive endpoint of survival to the beginning of hatching compared to 100% for the paired control eggs within the same nests. Microsampled black-necked stilt eggs exhibited 100% hatching success compared to 93% for the paired control eggs. Our results indicate that microsampling is an effective tool for nonlethally sampling mercury concentrations in eggs and, as such, can be used for monitoring sensitive species, as well as for improving studies that examine the effects of mercury on avian reproduction.

AN - 67134683; 19350918 AB - The collapse of the World Trade Center Towers on September 11, 2001, sent dust and debris across much of Manhattan and in the surrounding areas. Indoor and outdoor dust samples were collected and characterized by U.S. Geological Survey (USGS) scientists using scanning electron microscopy with energy-dispersive spectrometry (SEM/EDS). From this characterization, the U.S. Environmental Protection Agency and USGS developed a particulate screening method to determine the presence of residual World Trade Center dust in the indoor environment using slag wool as a primary "signature". The method describes a procedure that includes splitting, ashing, and sieving of collected dust From one split, a 10 mg/mL dust/isopropanol suspension was prepared and 10-30 microL aliquots of the suspension placed on an SEM substrate. Analyses were performed using SEM/EDS manual point counting for slag wool fibers. Poisson regression was used to identify some of the sources of uncertainty, which are directly related to the small number of fibers present on each sample stub. Preliminary results indicate that the procedure is promising for screening urban background dust for the presence of WTC dust. Consistent sample preparation of reference materials and samples must be performed by each laboratory wishing to use this method to obtain meaningful and accurate results.

AN - 67125550; 19350889 AB - Mathematical models of integrated solid waste management (SWM) are useful planning tools given the complexity of the solid waste system and the interactions among the numerous components that constitute the system. An optimization model was used in this study to identify and evaluate alternative plans for integrated SWM for the State of Delaware in consideration of cost and environmental performance, including greenhouse gas (GHG) emissions. The three counties in Delaware were modeled individually to identify efficient SWM plans in consideration of constraints on cost, landfill diversion requirements, GHG emissions, and the availability of alternate treatment processes (e.g., recycling, composting, and combustion). The results show that implementing a landfill diversion strategy (e.g., curbside recycling) for only a portion of the population is most cost-effective for meeting a county-specific landfill diversion target Implementation of waste-to-energy offers the most cost-effective opportunity for GHG emissions reductions.

AN - 67089870; 19337514 AB - Thirty years of pesticide registration toxicity data have been historically stored as hardcopy and scanned documents by the U.S. Environmental Protection Agency (EPA). A significant portion of these data have now been processed into standardized and structured toxicity data within the EPA's Toxicity Reference Database (ToxRefDB), including chronic, cancer, developmental, and reproductive studies from laboratory animals. These data are now accessible and mineable within ToxRefDB and are serving as a primary source of validation for U.S. EPA's ToxCast research program in predictive toxicology. We profiled in vivo toxicities across 310 chemicals as a model application of ToxRefDB, meeting the need for detailed anchoring end points for development of ToxCast predictive signatures. Using query and structured data-mining approaches, we generated toxicity profiles from ToxRefDB based on long-term rodent bioassays. These chronic/cancer data were analyzed for suitability as anchoring end points based on incidence, target organ, severity, potency, and significance. Under conditions of the bioassays, we observed pathologies for 273 of 310 chemicals, with greater preponderance (>90%) occurring in the liver, kidney, thyroid, lung, testis, and spleen. We observed proliferative lesions for 225 chemicals, and 167 chemicals caused progression to cancer-related pathologies. Based on incidence, severity, and potency, we selected 26 primarily tissue-specific pathology end points to uniformly classify the 310 chemicals. The resulting toxicity profile classifications demonstrate the utility of structuring legacy toxicity information and facilitating the computation of these data within ToxRefDB for ToxCast and other applications.

AN - 66981733; 19028983 AB - Triadimefon, propiconazole and myclobutanil are conazoles, an important class of agricultural and therapeutic fungicides. Triadimefon and propiconazole are mouse liver tumorigens, while myclobutanil is not. All three conazoles are generally inactive in short-term genotoxicity tests. We studied the in vivo mutagenicity of these three conazoles using the Big Blue mouse assay system. Groups of mice were fed either control diet or diet containing 1800 p.p.m. triadimefon, 2500 p.p.m. propiconazole or 2000 p.p.m. myclobutanil. After 4 days of feeding, mice were immediately euthanized, livers were removed, DNA isolated and lacI genes recovered into infectious bacteriophage lambda particles by in vitro packaging. Bacteriophage with mutations in the lacI gene was detected by infecting into Escherichia coli, and mutant frequencies were determined using a colorimetric plaque assay. Propiconazole induced a 1.97-fold increase in mutant frequency compared to concurrent controls (P = 0.018) and triadimefon induced a 1.94-fold increase compared to concurrent controls (P = 0.009). Myclobutanil did not induce any change in mutant frequency (P = 0.548). These results provide the first evidence that the hepatotumorigenic conazoles are capable of inducing mutations in liver in vivo while the non-tumorigen myclobutanil is not, suggesting that mutagenicity may represent a key event in conazoles tumorigenic mode of action.

AN - 66966813; 19244484 AB - Streams and rivers are a globally significant source of nitrous oxide (N(2)O), a potent greenhouse gas. However, there remains much uncertainty in the magnitude of N(2)O emissions from these sources, partly due to an incomplete understanding of the factors that control microbial N(2)O production in lotic sediments. During 2004-2005 we measured sediment N(2)O production in 12 headwater streams across an agricultural land use gradient. Stream water nitrate (NO(3)(-)) concentrations were positively related to the proportion of agricultural land use in the basin and frequently exceeded 20 mg N L(-1) in the stream draining the most agricultural basin. Stream sediments were nearly always a net source of N(2)O, and production rates were positively related to stream water NO(3)(-) concentrations and sediment carbon content. There were no seasonal patterns in N(2)O production rates during 2004, but stream water NO(3)(-) and N(2)O production both peaked during the winter of 2005. The spike in NO(3)(-) concentrations likely resulted from winter rain and snowmelt that flushed NO(3)(-) from the soils following a dry summer and fall. In turn, the elevated stream water NO(3)(-) concentrations stimulated in-stream N(2)O production rates. Overall, we were only able to explain 29% of the variation in N(2)O production rates on a log scale. The unexplained variation may be due to differences in the fraction of denitrified NO(3)(-) that is converted to N(2)O among the study sites, or that our measures of substrate availability in the water column were not reflective of substrate availability in the porewater used by denitrifiers.

AN - 66946905; 18853223 AB - The U.S. Environmental Protection Agency has proposed permitting ballast water discharges--a benefit of which would be to reduce the economic damages associated with the introduction and spread of aquatic invasive species. Research on ship-borne aquatic invasive species has been conducted in earnest for decades, but determining the economic damages they cause remains troublesome. Furthermore, with the exception of harmful algal blooms, the economic consequences of microscopic invaders have not been studied, despite their potentially great negative effects. In this paper, we show how to estimate the economic benefits of preventing the introduction and spread of harmful bacteria, microalgae, and viruses delivered in U.S. waters. Our calculations of net social welfare show the damages from a localized incident, cholera-causing bacteria found in shellfish in the Gulf of Mexico, to be approximately $706,000 (2006$). On a larger scale, harmful algal species have the potential to be transported in ships' ballast tanks, and their effects in the United States have been to reduce commercial fisheries landings and impair water quality. We examine the economic repercussions of one bloom-forming species. Finally, we consider the possible translocation within the Great Lakes of a virus that has the potential to harm commercial and recreational fisheries.

AN - 66945832; 19176365 AB - The interaction between air particulates and genetic susceptibility has been implicated in the pathogenesis of asthma. The overall objective of this study was to determine the effects of inhalation exposure to environmentally relevant concentrated air particulates (CAPs) on the lungs of ovalbumin (ova) sensitized and challenged Brown Norway rats. Changes in gene expression were compared with lung tissue histopathology, morphometry, and biochemical and cellular parameters in bronchoalveolar lavage fluid (BALF). Ova challenge was responsible for the preponderance of gene expression changes, related largely to inflammation. CAPs exposure alone resulted in no significant gene expression changes, but CAPs and ova-exposed rodents exhibited an enhanced effect relative to ova alone with differentially expressed genes primarily related to inflammation and airway remodeling. Gene expression data was consistent with the biochemical and cellular analyses of the BALF, the pulmonary pathology, and morphometric changes when comparing the CAPs-ova group to the air-saline or CAPs-saline group. However, the gene expression data were more sensitive than the BALF cell type and number for assessing the effects of CAPs and ova versus the ova challenge alone. In addition, the gene expression results provided some additional insight into the TGF-beta-mediated molecular processes underlying these changes. The broad-based histopathology and functional genomic analyses demonstrate that exposure to CAPs exacerbates rodents with allergic inflammation induced by an allergen and suggests that asthmatics may be at increased risk for air pollution effects.

AN - 66945762; 19098276 AB - These experiments sought to establish a dose-effect relationship between the concentration of perchloroethylene (PCE) in brain tissue and concurrent changes in visual function. A physiologically based pharmacokinetic (PBPK) model was implemented to predict concentrations of PCE in the brains of adult Long-Evans rats following inhalation exposure. The model was evaluated for performance against tissue concentrations from exposed rats (n = 40) and data from the published scientific literature. Visual function was assessed using steady-state pattern-elicited visual-evoked potentials (VEPs) recorded from rats during exposure to air or PCE in two experiments (total n = 84) with concentrations of PCE ranging from 250 to 4000 ppm. VEP waveforms were submitted to a spectral analysis in which the major response component, F2, occurring at twice the visual stimulation rate, was reduced in amplitude by PCE exposure. The F2 amplitudes were transformed to an effect-magnitude scale ranging from 0 (no effect) to 1 (maximum possible effect), and a logistical function was fit to the transformed values as a function of estimated concurrent brain PCE concentrations. The resultant function described a dose-response relationship between brain PCE concentration and changes in visual function with an ED(10) value of approximately 0.684 mg/l and an ED(50) value of approximately 46.5 mg/l. The results confirmed that visual function was disrupted by acute exposure to PCE, and the PBPK model and logistic model together could be used to make quantitative estimates of the magnitude of deficit to be expected for any given inhalation exposure scenario.

AN - 66926245; 18471900 AB - Noroviruses are the leading cause of nonbacterial gastroenteritis outbreaks in the United States, some of which are caused by the ingestion of contaminated water. Detection and genotypic characterization of noroviruses is commonly performed by reverse transcription-polymerase chain reaction (RT-PCR) followed by sequencing. However, sequencing of products amplified from environmental water samples is often hindered by the co-amplification of non-specific cDNA. To overcome this issue, a generic microarray was evaluated to genotype noroviruses by probe hybridization. RT-PCR amplicons are used in a single base extension (SBE) reaction where genotype-specific probes are labeled and then hybridized to an Affymetrix GeneChip GenFlex Tag Array for detection. Using a standardized, multiplex SBE reaction, genotyping of representative strains was accomplished through the identification of genotype-specific patterns of positive hybridization results. Furthermore, the SBE-GenFlex array method was successful in the genotype identification of noroviruses seeded into tap and Ohio River water samples. This study shows the utility of using a microarray to genotype noroviruses in complex environmental matrices.

AN - 66900709; 19082748 AB - The coastal waters of American Samoa's five high islands (Tutuila, Aunu'u, Ofu, Olosega, and Ta'u) were surveyed in 2004 using a probabilistic design. Water quality data were collected from the near-shore coastal habitat, defined as all near-shore coastal waters including embayments, extending out to 1/4 mile off-shore. Hydrography and water column samples were collected, and water quality data were compared to the Territorial water quality standards for pH, dissolved oxygen (DO), Enterococcus, chlorophyll a, water clarity, total nitrogen, and total phosphorus. All station measurements for pH, DO, and Enterococcus satisfied the local water quality standards, although some fraction of the Territory could not be assessed for either DO or Enterococcus. With respect to chlorophyll a, 66 +/- 18% of Territory coastal waters complied with the standard, while 34 +/- 18% failed to comply with the standard. For water clarity, 54 +/- 18% of the Territorial waters complied with the standard while 42 +/- 7% failed to comply. Territorial waters satisfied the standards for total nitrogen and phosphorus 72 +/- 17% and 92 +/- 10%, respectively. These data provide the first "big-picture" view of water quality in the near shore region around the high islands of American Samoa. While the picture is encouraging, these data suggest emerging water quality concerns.

AN - 66900283; 19083112 AB - The Mobile Bay estuary in the northern Gulf of Mexico provides a rich habitat for many fish and shellfish, including those identified as economically and ecologically important. The National Estuary Program in Mobile Bay has focused on restoration of degraded estuarine habitat on which these species depend. To support this effort, we used statistical techniques of ordination, cluster analysis, and discriminant analysis to relate distributions of individual fish and shellfish species and species assemblages to two dozen water quality and habitat variables in a geo-referenced database. Species appeared to respond to dominant gradients of low to high salinity and upland to offshore habitat area; many of the 15 communities identified via cluster analysis showed aggregated spatial distributions that could be related to habitat characteristics. Species in the Mobile River Delta were distinct from those in other areas of the estuary. This analysis supports habitat management in the Mobile Bay estuary; however, due to mobility of organisms among sampling locations and the dynamic environmental conditions in estuaries, we conclude that the analyses presented here are most appropriate for an evaluation of the estuary as a whole.

AN - 66900252; 19067201 AB - An unequal probability design was used to develop national estimates for 268 persistent, bioaccumulative, and toxic chemicals in fish tissue from lakes and reservoirs of the conterminous United States (excluding the Laurentian Great Lakes and Great Salt Lake). Predator (fillet) and bottom-dweller (whole body) composites were collected from 500 lakes selected randomly from the target population of 147,343 lakes in the lower 48 states. Each of these composite types comprised nationally representative samples whose results were extrapolated to the sampled population of an estimated 76,559 lakes for predators and 46,190 lakes for bottom dwellers. Mercury and PCBs were detected in all fish samples. Dioxins and furans were detected in 81% and 99% of predator and bottom-dweller samples, respectively. Cumulative frequency distributions showed that mercury concentrations exceeded the EPA 300 ppb mercury fish tissue criterion at nearly half of the lakes in the sampled population. Total PCB concentrations exceeded a 12 ppb human health risk-based consumption limit at nearly 17% of lakes, and dioxins and furans exceeded a 0.15 ppt (toxic equivalent or TEQ) risk-based threshold at nearly 8% of lakes in the sampled population. In contrast, 43 target chemicals were not detected in any samples. No detections were reported for nine organophosphate pesticides, one PCB congener, 16 polycyclic aromatic hydrocarbons, or 17 other semivolatile organic chemicals.

AN - 66897735; 19037735 AB - The Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS) initiated a two-year regional pilot survey in 2007 to develop, test, and validate tools and approaches to assess the condition of northern Gulf of Mexico (GOM) coastal wetlands. Sampling sites were selected from estuarine and palustrine wetland areas with herbaceous, forested, and shrub/scrub habitats delineated by the US Fish and Wildlife Service National Wetlands Inventory Status and Trends (NWI S&T) program and contained within northern GOM coastal watersheds. A multi-level, stepwise, iterative survey approach is being applied to multiple wetland classes at 100 probabilistically-selected coastal wetlands sites. Tier 1 provides information at the landscape scale about habitat inventory, land use, and environmental stressors associated with the watershed in which each wetland site is located. Tier 2, a rapid assessment conducted through a combination of office and field work, is based on best professional judgment and on-site evidence. Tier 3, an intensive site assessment, involves on-site collection of vegetation, water, and sediment samples to establish an integrated understanding of current wetland condition and validate methods and findings from Tiers 1 and 2. The results from this survey, along with other similar regional pilots from the Mid-Atlantic, West Coast, and Great Lakes Regions will contribute to a design and implementation approach for the National Wetlands Condition Assessment to be conducted by EPA's Office of Water in 2011.

Designing near-road air monitoring networks or interpreting previously collected near-road monitoring data is essential for transportation system planning, environmental impact assessments, and exposure assessments in health studies. For these applications, care must be taken in determining the pollutants of interest for both air quality and health assessments. In addition, planners and data analysts need to evaluate and understand the potential influence of the roadway type, design, and presence of roadside structures on the potential transport and dispersion of traffic-emitted pollutants on these air quality and health evaluations. This paper summarizes key factors related to the collection and interpretation of near-road air quality data from the perspective of the pollutants of interest and the location of the monitoring sites.

Benthic macrofaunal samples, sediment chemical concentrations, and water quality measurements from 60 sites in Lake Pontchartrain and Mississippi Sound were compared with pre-hurricane conditions from 2000-2004. Post-hurricane benthic communities had significant reductions in numbers of taxa, H' diversity, and abundance as well as shifts in composition and ranking of dominant taxa. These effects were not associated with changes in chemical contamination, organic enrichment of sediments, or hypoxia and were likely due to hurricane-related scouring and changes in salinity.

Rapid improvements in information technology and strong interest in biodiversity and sustainable ecosystems are driving a vigorous phase of development in ecological databases. Emerging data standards and protocols enable these data to be shared in ways that have previously been difficult. We use the U.S. Environmental Protection Agency's National Coastal Assessment (NCA) as an example. The NCA has collected biological, chemical, and physical data from thousands of stations around the U.S. coasts since 1990. NCA data that were collected primarily to assess the ecological condition of the U.S. coasts can be used in innovative ways, such as biogeographical studies to analyze species invasions. NCA application of ecoinformatics tools leads to new possibilities for integrating the hundreds of thousands of NCA species records with other databases to address broad-scale and long-term questions such as environmental impacts, global climate change, and species invasions.

This study included the largest set (268) of persistent, bioaccumulative, and toxic (PBT) chemicals ever studied in predator and bottom-dwelling fish species. The U.S. Environmental Protection Agency (USEPA) implemented the study in cooperation with states, tribal nations, and other federal agencies, with field collection occurring at 500 lakes and reservoirs over a four-year period (2000-2003). The sampled lakes and reservoirs were selected using a spatially balanced unequal probability survey design from 270,761 lake objects in USEPA's River Reach File Version 3 (RF3). The survey design selected 900 lake objects, with a reserve sample of 900, equally distributed across six lake area categories. A total of 1,001 lake objects were evaluated to identify 500 lake objects that met the study's definition of a lake and could be accessed for sampling. Based on the 1,001 evaluated lakes, it was estimated that a target population of 147,343 (c7% with 95% confidence) lakes and reservoirs met the NLFTS definition of a lake. Of the estimated 147,343 target lakes, 47% were estimated not to be sampleable either due to landowner access denial (35%) or due to physical barriers (12%). It was estimated that a sampled population of 78,664 (c12% with 95% confidence) lakes met the NLFTS lake definition, had either predator or bottom-dwelling fish present, and could be sampled.

Warmer sea temperatures attributed to global climate change and numerous human activities at local scales place these valuable ecosystems at risk. Reefs provide numerous services, including shoreline protection, fishing, tourism and biological diversity, which are lost through physical damage, overfishing, and pollution. Pollution can be controlled under provisions of the Clean Water Act, but these options have not been fully employed to protect coral reefs. No U.S. jurisdiction has implemented coral reef biocriteria, which are narrative or quantitative water quality standards based on the condition of a biological resource or assemblage. The President's Ocean Action Plan directs the U.S. Environmental Protection Agency (EPA) to develop biological assessment methods and biological criteria for evaluating and maintaining the health of coral reef ecosystems. EPA has formed the Coral Reef Biocriteria Working Group (CRBWG) to foster development of coral reef biocriteria through focused research, evaluation and communication among Agency partners and U.S. jurisdictions. Ongoing CRBWG activities include development and evaluation of a rapid bioassessment protocol for application in biocriteria programs; development of a survey design and monitoring strategy for the U.S. Virgin Islands; comprehensive reviews of biocriteria approaches proposed by states and territories; and assembly of data from a variety of monitoring programs for additional metrics. Guidance documents are being prepared to assist U.S. jurisdictions in reaching protective and defensible biocriteria.

PCB toxicology, ecological theory, and some precedence supported expectations of increased susceptibility to pathogens in NB killifish. However, laboratory bacterial challenges of the marine pathogen Vibrio harveyi to wild fish throughout the reproductive season and to their mature laboratory-raised progeny demonstrated comparable survival by NB and reference killifish, and improved survival by NB males. These results are inconsistent with hypothesized trade-offs of adaptation, and suggest that evolved tolerance in NB killifish may include mechanisms that minimize the immunosuppressive effects of PCBs. Compensatory strategies of populations persisting in highly contaminated environments provide a unique perspective for understanding the long-term ecological effects of toxic chemicals.

Removal and/or treatment of these AMD sources is desired to return the impacted stream(s) to initial conditions, or at least to conditions suitable for restoration of the aquatic ecosystem. Some expected changes in the water chemistry of the stream following removal of AMD input include an increase in pH, a decrease in ionic strength, and an increase in dissolved organic carbon (DOC) concentrations from increased biological activity in the absence of toxic metals concentrations. These changes in water chemistry may cause the existing contaminated bed sediments to become a source of metals to the stream water. Streambed sediments, collected from North Fork Clear Creek (NFCC), Colorado, currently impacted by AMD, were assessed for the effects of pH, ionic strength, DOC concentration, time, and particle size on metals release using a factorial design. The design included two levels for each chemical parameter (ionic strength=40 and 80% lower than ambient; pH=6 and 8; and DOC=1 and 3mg/l higher than ambient), ten sampling times (from zero to 48h), and two size fractions of sediments (63km?x<2mm and <63km). Greater concentrations of metals were released from the smaller sized sediments compared with the larger, with the exception of Cu. A mild acid digestion (0.6M HCl) evaluated the amount of each metal that could be removed easily from each of the sediment size fractions. Release of all metals over all time points, treatments, and from both sediment sizes was less than 1% of the extractable concentrations, with the exception of Mn, which ranged from 4 to 7% from the smaller sized sediment. Greater percentages of the 0.6M HCl-extractable concentrations of Cu, Fe, and Zn were released from the larger sized sediment, while this was true for release of Cd and Mn from the smaller sized sediment. Thus, at least for Cd and Mn, the observed higher concentrations released from the smaller sized sediment with each treatment solution is not simply a function of these particles having higher concentrations available for release, but that these metals also are more readily released from the smaller sediment particles versus the larger. DOC concentration strongly influenced the release of Cu; ionic strength strongly influenced the release of Cd, Mn, and Zn; and interaction effects were observed with the release of Cu, Mn, and Zn from the larger size fraction and with the release of Zn from the smaller size fraction. Overall, results suggest that the expected changes in water chemistry following removal/treatment of the AMD sources would result in a release of metals from the existing sediments, with a greater effect on the release of Cu and Fe, than on the release of Cd, Mn, and Zn.

One expanding area of research not well emphasized to date is the endocrine effects of Hg. This review summarizes the existing literature on the effects of Hg on the endocrine system and identifies gaps in the knowledge. It focuses on the thyroid, adrenal, and reproductive systems, including the accumulation of Hg in the endocrine system, sex differences that are manifested with Hg exposure, reproductive effects in male and female animals including humans, and Hg effects on the thyroid and adrenal systems. We concluded that there are five main endocrine-related mechanisms of Hg across these systems: (a) accumulation in the endocrine system; (b) specific cytotoxicity in endocrine tissues; (c) changes in hormone concentrations; (d) interactions with sex hormones; and (e) up-regulation or down-regulation of enzymes within the steroidogenesis pathway. Recommendations for key areas of research to better understand how the endocrine effects of Hg affect human and wildlife health were developed, and include increasing the amount of basic biological information available about Hg and wildlife species, exploring the role of Hg in the presence of other stressors and chemicals, understanding sublethal and indirect effects of Hg on adverse outcomes, developing better methods to extrapolate effects across species, and understanding the effects of Hg on multiple organ systems following exposure of an animal. Greater inclusion of endocrine endpoints in epidemiological and field studies on humans and wildlife will also advance the research in this area.

Telomerase-containing human telomerase reverse transcriptase (hTERT) can extend telomeres of chromosomes, delay senescence, and promote cell proliferation leading to tumorigenesis. OBJECTIVE: The goal of this study was to investigate the effects of As on hTERT mRNA expression in humans and in vitro. Method: A total of 324 Inner Mongolia residents who have been exposed to As via drinking water participated in this study. Water and toenail samples were collected and analyzed for As. Blood samples were quantified for hTERT mRNA expression using real-time polymerase chain reaction. The hTERT mRNA levels were linked to water and nail As concentrations and skin hyperkeratosis. Human epidermal keratinocytes were treated with arsenite to assess effects on cell viability and hTERT expression in vitro. RESULTS: hTERT mRNA expression levels were significantly associated with As concentrations of water (p < 0.0001) and nails (p = 0.002) and also associated with severity of skin hyperkeratosis (p < O.O5), adjusting for age, sex, smoking, and pesticide use. Females showed a higher slope than males (females: 0.126, p = 0.0005; males: 0.079, p = 0.017). In addition to water and nail As concentrations, age (p < 0.0001) and pesticide use (p = 0.025) also showed significant associations with hTERT expression. The hTERT expression levels decreased with age. Tobacco smoking did not affect hTERT expression (p = 0.13). hTERT expression was significantly correlated with OGG1 and ERCC1 expression. The in vitro results also showed a dose--response relationship between arsenite concentrations and hTERT expression and reached the peak at 1 kM. Conclusions: hTERT expression was associated with As exposure in vivo and in vitro. The increased hTERT expression may be a cellular response to genomic insults by As and may also indicate that As may function as a tumor promoter in carcinogenesis in humans.

Deaths occurring between January 1, 1997 and December 1, 2004 were classified according to underlying cause and water samples from household wells were tested for total arsenic. Heart disease mortality was associated with arsenic exposure, and the association strengthened with time exposed to the water source. Cancer mortality and all-cause mortality were associated with well-water arsenic exposure among those exposed 10-20 years. This is the first study to document increased arsenic-associated mortality in the Bayingnormen region of Inner Mongolia.

LM2-Toxic couples the organic carbon sorbent and chemical dynamics conceptualized for a natural water system. Based on 1994-1995 model results, a mass budget analysis showed that air-water exchange was the most important mass transfer process. Volatilization was the largest PCB loss and gas absorption was the largest PCB input to Lake Michigan. Model-predicted environmental exposure concentrations suggest that the water quality criterion for protection of wildlife (0.074 ng/L) and human health (0.026 ng/L) will be attained in approximately 2018 and 2045, respectively, based on a slow recovery scenario. For this scenario, atmospheric components, including vapor phase concentration and wet and dry particulate loadings, were assumed to decline with a 20 year half-life, and tributary loadings were assumed to decline with a 13 year half-life.

This review summarizes reported concentrations of anthropogenic chemicals in grass bed-associated surface waters, sediments, and plant tissues and phytotoxic concentrations. Fate information in seagrass-rooted sediments and overlying water is most available for trace metals. Toxicity results in aqueous exposures are available for at least 13 species and a variety of trace metals, pesticides, and petrochemicals. In contrast, results for chemical mixtures and chemicals in sediment matrices are uncommon. Contaminant bioaccumulation information is available for at least 23 species. The effects of plant age, tissue type, and time of collection have been commonly reported but not biological significance of the chemical residues. Experimental conditions have varied considerably in seagrass contaminant research and interspecific differences in chemical residues and chemical tolerances are common, which limits generalizations and extrapolations among species and chemicals. The few reported risk assessments have been usually local and limited to a few single chemicals and species representative of the south Australian and Mediterranean floras. Media-specific information describing exposure concentrations, toxic effect levels, and critical body burdens of common near-shore contaminants is needed for most species to support integrated risk assessments at multiple geographical scales and to evaluate the ability of numerical effects-based criteria to protect these marine angiosperms at risk.

Less is known about the relative impacts of the specific chemical constituents of paniculate matter < 2.5 pm in aerodynamic diameter (PM sub(2.5)) on hospital admissions. OBJECTIVE: Ibis study was designed to estimate the risks of exposure to PM2.5 and several species on hospital admissions for respiratory diseases among children. Data AND METHODS: We obtained data on daily counts of hospitalizations for children < 19 and < 5 years of age for total respiratory diseases and several subcategories including pneumonia, acute bronchitis, and asthma for six California counties from 2000 through 2003, as well as ambient concentrations of PM2.5 and its constituents, including elemental carbon (EC), organic carbon (OC), and nitrates (NO sub(3)). We used Poisson regression to estimate risks while controlling for important covariates. Results: We observed associations between several components of PM sub(2.5) and hospitalization for all of the respiratory outcomes examined. For example, for total respiratory admissions for children < 19 years of age, the interquartile range for a 3-day lag of PM sub(2.5), EC, OC, NO sub(3), and sulfates was associated with an excess risk of 4.1% [95% confidence interval (CI), 1.8-6.4], 5.4% (95% CI, 0.8-10.3), 3.4% (95% CI, 1.1-5.7), 3.3% (95% CI, 1.1-5.5), and 3.0% (95% CI, 0.4-5.7), respectively. We also observed associations for several metals. Additional associations with several of the species, including potassium, were observed in the cool season. Conclusion: Components of PM2.5 were associated with hospitalization for several childhood respiratory diseases including pneumonia, bronchitis, and asthma. Because exposure to components (e.g., EC, OC, NO3, and K) and their related sources, including diesel and gasoline exhaust, wood smoke, and other combustion sources, are ubiquitous in the urban environment, it likely represents an identifiable and preventable risk factor for hospitalization for children.

Snag assemblages differed from benthic assemblages. Tubificids, Caenis, Tanytarsus, Cryptochironomus, Limnodrilus, and Chironomini were consistently more abundant in the benthos; Nais, Cricotopus/Orthocladius, Nematoda, and Rheotanytarsus were consistently more abundant on snags. Filterers were more abundant and gatherers were less abundant on snags than in the benthos. Snag assemblages differed among rivers and among reaches within rivers. Variation among reaches was the result of direct and indirect effects of high-dam reservoir impoundments (upper vs lower Missouri River) and low-dam impoundment for navigation (impounded vs free-flowing Upper Mississippi River). The maximum relative abundance of filterers in the lower Missouri River, which was the only long unregulated reach we studied, was related to particulate organic C and sestonic chlorophyll a concentration, which increased with distance downriver from the lowest main-stem dam. Snag diameter, snag-surface characteristics, and water depth did not affect the composition of snag assemblages, but the dominant taxa on snags in fast-velocity locations were different from the dominant taxa on snags in slow-velocity locations. Relatively few taxa showed strong longitudinal patterns in relative abundance within a reach, and only on the Missouri River. We hypothesize that the many navigation dams on the Ohio and Upper Mississippi rivers suppress the development of environmental gradients and inhibit the formation of longitudinal patterns in macroinvertebrate assemblages. Snag assemblages were dominated by a few taxa (genus-level and higher), a characteristic that might constrain the sensitivity of the assemblages to some human impacts. Sampling snag assemblages has potential for great-river bioassessment, but further research is necessary on sampling methods and sensitivity of assemblages to stressors.

We describe a process to screen indices for associations and, after identifying candidate metrics, evaluate metrics individually against the indices. We utilize radar plots as a multi-metric visualization tool, and conditional probability plots and receiver operating characteristic curves to evaluate associations seen in the plots. We investigated differences in two indices, the US EPA Environmental Monitoring and Assessment Program's benthic index for the Virginian Province and the New York Harbor benthic index of biotic integrity using data collected in New York Harbor and evaluated overall agreement of the indices and associations between each index and measures of habitat and sediment contamination. The indices agreed in approximately 78% of the cases. The New York Harbor benthic index of biotic integrity showed stronger associations with sediment metal contamination and grain size.

A key challenge is to integrate these three components on a consistent spatial and temporal basis taking into account linkages and feedbacks. The current state-of-practice for such assessments is to exercise emission, meteorology, air quality, exposure, and dose models separately, and to link them together by using the output of one model as input to the subsequent downstream model. Quantification of variability and uncertainty has been an important topic in the exposure assessment community for a number of years. Variability refers to differences in the value of a quantity (e.g., exposure) over time, space, or among individuals. Uncertainty refers to lack of knowledge regarding the true value of a quantity. An emerging challenge is how to quantify variability and uncertainty in integrated assessments over the source-to-dose continuum by considering contributions from individual as well as linked components. For a case study of fine particulate matter (PM sub(2) sub(.) sub(5)) in North Carolina during July 2002, we characterize variability and uncertainty associated with each of the individual concentration, exposure and dose models that are linked, and use a conceptual framework to quantify and evaluate the implications of coupled model uncertainties. We find that the resulting overall uncertainties due to combined effects of both variability and uncertainty are smaller (usually by a factor of 3-4) than the crudely multiplied model-specific overall uncertainty ratios. Future research will need to examine the impact of potential dependencies among the model components by conducting a truly coupled modeling analysis.

Measurements were made during the summers of 2003 and 2004 on 16 dates distributed along depth and salinity gradients. Dissolved oxygen fluxes were measured on replicate sediment and water column samples exposed to a gradient of photosynthetically active radiation. Sediment inorganic nutrient (NH sub(4) super(+), NO sub(3) super(-), PO sub(4) super(3) super(-)) fluxes were measured. The response of dissolved oxygen fluxes to variation in light was fit to a photosynthesis-irradiance model and the parameter estimates were used to calculate daily integrated production in the water column and the benthos. The results suggest that shoal environments supported substantial benthic productivity, averaging 13.6+ /-4.7mmolO sub(2)m super(-) super(2)d super(-) super(1), whereas channel environments supported low benthic productivity, averaging 0.5+/-0.3mmolO sub(2)m super(-) super(2)d super(-) super(1) (+/-SE). Estimates of baywide microphytobenthic productivity ranged from 8.1 to 16.5mmolO sub(2)m super(-) super(2)d super(-) super(1), comprising about 16-32% of total system productivity. Benthic and water column dark respiration averaged 15.2+/-3.2 and 33.6+ /-3.7mmolO sub(2)m super(-) super(2)d super(-) super(1), respectively Inorganic nutrient fluxes were generally low compared to relevant estuarine literature values, and responded minimally to light exposure. Across all stations, nutrient fluxes from sediments to the water column averaged 1.11+/-0.98mmolm super(-) super(2)d super(-) super(1) for NH sub(4) super(+), 0.58+ /-1.08mmolm super(-) super(2)d super(-) super(1) for NO sub(3) super(-), 0.01+/-0.09mmolm super(-) super(2)d super(-) super(1) for PO sub(4) super(3) super(-). The results of this study illustrate how light reaching the sediments is an important modulator of benthic nutrient and oxygen dynamics in shallow estuarine systems.

The study objective was to evaluate the potential of each component extract to induce allergic/asthma-like responses observed in this mouse model. BALB/c mice received 4 IA exposures to MACA, CON, MYC, IND, or bovine serum albumin (BSA; negative control) or appropriate vehicle control or inflammatory control over a 4-wk period. Mice were assessed by whole-body plethysmography for immediate airway responses and airway hyperresponsiveness to methacholine (Mch) challenge (PenH). Serum and bronchoalveolar lavage fluid (BALF) were collected 3 d after the final exposure. Additionally, BALF neurotrophin levels and extract protease and chitinase activity levels were evaluated. Western blot analysis showed that each component contained different IgE-reactive proteins. All fungal extract exposures resulted in elevated BALF total and differential cell counts, IgE and IgA and total serum IgE compared to HBSS and BSA controls. MYC-exposed mice had the highest responses except for neutrophil influx, which was highest in MACA and IND exposures. However, the MYC-exposed mice had significantly lower PenH values compared to other treatments. By comparison IND and MACA induced significantly higher PenH values. Additionally, IND had substantially higher protease activity levels but induced the lowest neurotrophin levels compared to the other fungal exposures. In this allergic asthma model extract chitinase activity was not associated with allergic responses. In summary, multiple exposures to any of the M. anisopliae component extracts induced allergic/asthma-like responses in BALB/c mice but the response magnitude was different for each component and each appears to contain unique IgE-reactive proteins. Therefore, hazard identification and/or risk assessment for molds must test both mycelia and conidia.

We developed a regional macroinvertebrate index and assessed relative condition of six large river tributaries to the upper Mississippi and Ohio rivers, Midwest USA. In 2004 and 2005, benthic macroinvertebrates, water chemistry, and habitat data were collected from randomly selected sites on each of the St. Croix, Wisconsin, Minnesota, Scioto, Wabash, and Illinois rivers. We first identified the human disturbance gradient using principal components analysis (PCA) of abiotic data. From the PCA, least disturbed sites showed strong separation from stressed sites along a gradient contrasting high water clarity, canopy cover, habitat scores, and plant-based substrates at one end and higher conductivity and nutrient concentrations at the other. Evaluation of 97 benthic metrics identified those with good range, responsiveness, and relative scope of impairment, as well as redundancies with other metrics. The final index was composed of Diptera taxa richness, EPT taxa richness, Coleoptera taxa richness, percent oligochaete and leech taxa, percent collector-filterer individuals, predator taxa richness, percent burrower taxa, tolerant taxa richness, and percent facultative individuals. Each of the selected metrics was scored using upper and lower thresholds based on all sites, and averaging across the nine metric scores, we obtained the Non-wadeable Macroinvertebrate Assemblage Condition Index (NMACI). The NMACI showed a strong response to disturbance using a validation data set and was highly correlated with non-metric multidimensional scaling (NMDS) ordination axes of benthic taxa. The cumulative distribution function of index scores for each river showed qualitative differences in condition among rivers. NMACI scores were highest for the federally protected St. Croix River and lowest for the Illinois River. Other rivers were intermediate and generally reflected the mixture of land use types within individual basins. Use of regional reference sites, though setting a high level of expectation, provides a valuable frame of reference for the potential of large river benthic communities that will aid management and restoration efforts.

The exposures were conducted using either 10 ng/l or 100 ng/l EE2 via a continuous flow water delivery system. Livers were collected at 1, 4, and 8 days of the exposure and 8 days after the chemical was removed from the water (i.e. an 8 day depuration). The exposure resulted in a number of sex-specific changes in lipid profiles that were also highly time dependent. Those metabolites most affected by exposure included phosphatidylcholine, diglycerides, triglycerides and cholesterol. In addition, changes in the length and degree of unsaturation of hepatic fatty acids were observed. Lipid profiles in plasma for fish collected on the 4th day of exposure were also analyzed in order to provide further insights into changes observed in hepatic metabolite changes. Using validated partial least-squares discriminant analysis (PLS-DA), the response trajectories of the male liver lipid profiles at both exposure concentrations were compared. This analysis indicated that the males exposed to the low concentration of EE2 (10 ng/l) were largely able to recover from the exposure once the chemical was removed from the water. Conversely, the males exposed to the high concentration (100 ng/l) did not appear to recover from the exposure despite the 8 day depuration.

A total of 72 ground water samples were collected from 12 PCE or TCE contaminated sites in the United States. The samples were analyzed and used to construct microcosms in the laboratory. The results showed that the presence of Dehalococcoides DNA was well associated with dechlorination to ethene in the field. Nearly half of the wells where Dehalococcoides DNA was detected had ethene as a dechlorination end product. In comparison, for ground water samples of 16 wells where ethene was detected, ethene was produced in 11 of the corresponding microcosms. For most microcosms, during two years of incubation, dechlorination was less extensive than that observed in the field.

We hypothesized that 48 h exposures of female fathead minnows (Pimephales promelas) to environmentally relevant concentrations of these chemicals would alter genes regulated by the androgen receptor and that a mixture of the two compounds would block the effects. Gene expression in the ovaries was analyzed using a fathead minnow-specific 22000-gene microarray. Flutamide altered about twice the number of genes as trenbolone, most of which appeared to be through pathways not associated with the androgen receptor. A group of 70 genes, of which we could identify 37, were reciprocally regulated by trenbolone and flutamide. These are candidates for specific biomarkers for androgen receptor mediated gene expression. Four genes stand out as specifically related to reproduction: sperm associated antigen 8 (SPAG8), CASP8 and FADD-like apoptosis regulator (CFLAR), corticotropin releasing hormone (CRH), and 3*b-hydroxysteroid dehydrogenases (3*b-HSD). Three notable transcriptional regulators including myelocytomatosis viral oncogene homologue (MYC), Yin Yang 1 (YY1), and interferon regulator factor 1 (IRF1) may function as early molecular switches to control phenotypic changes in ovary tissue architecture and function in response to androgen or antiandrogen exposure.

Because the DEHP emission rate measured in a test chamber may be quite different from the emission rate from the same material in the indoor environment, the model provides a convenient means to predict emissions and transport in a more realistic setting. Adsorption isotherms for phthalates and plasticizers on interior surfaces, such as carpet, wood, dust, and human skin, are derived from previous field and laboratory studies. Log-linear relationships between equilibrium parameters and chemical vapor pressure are obtained. The predicted indoor air DEHP concentration at steady state is 0.15 *mg/m3. Room 1 reaches steady state within about one year, while the adjacent room reaches steady state about three months later. Ventilation rate has a strong influence on DEHP emission rate while total suspended particle concentration has a substantial impact on gas-phase concentration. Exposure to DEHP via inhalation, dermal absorption, and oral ingestion of dust is evaluated. The model clarifies the mechanisms that govern the release of DEHP from vinyl flooring and the subsequent interactions with interior surfaces, airborne particles, dust, and human skin. Although further model development, parameter identification, and model validation are needed, our preliminary model provides a mechanistic framework that elucidates exposure pathways for phthalate plasticizers, and can most likely be adapted to predict emissions and transport of other semivolatile organic compounds, such as brominated flame retardants and biocides, in a residential environment.

AN - 67069146; 19320155 AB - Model studies have demonstrated that electron shuttles (ES) such as dissolved organic matter (DOM) can participate in the reduction of organic contaminants; however, much uncertainty exists concerning the significance of this solution phase pathway for contaminant reduction in natural systems. To compare the identity and reactivity of ES in anaerobic sediments with those in model systems, two chemical probes (4-cyano-4'-aminoazobenzene (CNAAzB) either free or covalently bound to glass beads) were synthesized that allowed for differentiation between surface-associated and solution-phase electron-transfer processes. The feasibility of these chemical probes were demonstrated in abiotic model systems (Fe(II)/Fe(III) oxide) and biotic model systems (Fe(II)/Fe(III) oxide or river sediment amended with S. putrefaciens strain cells). Experiments in the abiotic systems revealed that the addition of model hydroquinones and chemically reduced DOM increased reduction rates of free CNAAzB, whereas no enhancement in reactivity was observed with the addition of model quinones or DOM. Bound CNAAzB was also reduced by model hydroquinones and reduced DOM--but not by model quinones and untreated DOM--in the abiotic model systems, indicating that Fe(II)/Fe(III) oxides do not function as a bulk reductant forthe reduction of ES. Addition of model quinones or untreated DOM to the biotic models systems with sediment increased reduction rates of bound CNAAzB, which correlated well with the dissolved organic carbon content. In natural sediment slurries, reduction rates of bound CNAAzB correlated well with parameters for organic carbon (OC) content of both sediments and supernatants. Our results support a scenario in which reducible organic contaminants will compete with iron oxides for the electron flow generated by the microbially mediated oxidation of organic carbon and subsequent reduction of quinone functional groups associated with DOM.

We evaluated the mutagenicity in Salmonella TA98, TA100, and TA104 of two sulfur-containing derivatives of benzo[c]phenanthrene, phenanthro[3,4-b]thiophene (P[3,4-b]T), and phenanthro[4,3-b]thiophene (P[4,3-b]T) as well as their dihydrodiol and sulfone derivatives. In addition, we assessed levels of stable DNA adducts (by super(3) super(2)P-postlabeling) as well as abasic sites (by an aldehydic-site assay) produced by six of these compounds in TA100. P[3,4-b]T and its 6,7- and 8,9-diols, P[3,4-b]T sulfone, P[4,3-b]T, and its 8,9-diol were mutagenic in TA100. P[3,4-b]T sulfone, the most potent mutagen, was approximately twice as potent as benzo[a]pyrene in both TA98 and TA100. Benzo-ring dihydrodiols were much more potent than K-region dihydrodiols, which had little or no mutagenic activity in any strain. P[3,4-b]T sulfone produced abasic sites and not stable DNA adducts; the other five compounds examined, B[c]P, B[c]P 3,4-diol, P[3,4-b]T, P[3,4-b]T 8,9-diol, and P[4,3-b]T 8,9-diol, produced only stable DNA adducts. P[3,4-b]T sulfone was the only compound that produced significant levels of frameshift mutagenicity and induced mutations primarily at GC sites. In contrast, B[c]P, its 3,4-diol, and the 8,9 diols of the phenanthrothiophenes induced mutations primarily at AT sites. P[3,4-b]T was not mutagenic in TA104, whereas P[3,4-b]T sulfone was. The two isomeric forms (P[3,4-b]T and P[4,3-b]T) are apparently activated differently, with the latter, but not the former, involving a diol pathway. This study is the first illustrating the potential importance of abasic sites in the mutagenicity of thia-PAHs.

AN - 66984692; 19243027 AB - Endosulfan has been used for over 50 years. Although most analogs have been discontinued, endosulfan has less environmental persistence. Nevertheless, pressure groups are lobbying for a worldwide ban. The reasons are: possible rodent male reproductive toxicity, other endocrine effects and cancer; human epidemiology, and exposure studies; residues appearing in remote areas of the world, e.g., the Arctic. The endosulfan toxicology database is described and risks of its use assessed. Endosulfan is an antagonist at the GABA(A) receptor Cl(-) ionophore in mammalian CNS. Rat acute toxicity is moderate, LD(50)=48 (M) or 10 mg/kg/d (F), oral gavage; 130 (M), 70 mg/kg/d (F) dermal; LC(50)=34.5 microg/L (M), 12.6 microg/L (F), inhalation. Critical NOELs for risk assessment: acute oral (gavage)=0.7 mg/kg/d (rabbit developmental); Subchronic oral (diet)=1.2 mg/kg/d (rat reproduction); Chronic oral (diet)=0.6 mg/kg/d. There were no acceptable dermal toxicity studies. The critical acute and subchronic inhalation NOELs=0.001 mg/L, chronic inhalation=0.0001 mg/L (estimated). Toxicity to rat sperm occurred at doses causing neurotoxicity. Endocrine effects, resulting from P450 oxygenase(s) induction, were reversible. Increased cancer, genotoxicity, or histopathology in rodents was not observed in any organ. Possible effects on brain biogenic amine levels were probably secondary. Epidemiology and rodent studies suggesting autism and male reproductive toxicity are open to other interpretations. Developmental/ reproductive toxicity or endocrine disruption occurs only at doses causing neurotoxicity. Toxicity to the fetus or young animals is not more severe than that shown by adults.

AN - 66967133; 19245035 AB - This study explores the transformation of trichloroethene (TCE) caused by heating contaminated soil and groundwater samples obtained from the East Gate Disposal Yard (EGDY) located in Fort Lewis, WA. After field samples transferring into glass ampules and introducing 1.5 micromol of TCE, the sealed ampules were incubated at temperatures of 25, 50, and 95 degrees C for periods of up to 95.5 days. Although TCE was completely transformed into cis-1,2-dichloroethene (cis-DCE) after 42 days at 25 degrees C by microbial activity, this transformation was not observed at 50 or 95 degrees C. Chloride levels increased after 42 days at 25 degrees C corresponding to the mass of TCE transformed to cis-DCE, were constant at 50 degrees C, and increased at 95 degrees C yielding a TCE degradation half-life of 1.6-1.9 years. These findings indicate that indigenous microbes contribute to the partial dechlorination of TCE to cis-DCE at temperatures of less than 50 degrees C, whereas interphase mass transfer and physical recovery of TCE will predominate over in situ degradation processes at temperatures of greater than 50 degrees C during thermal treatment at the EGDY site.

AN - 66855334; 19027135 AB - Ten organophosphate (OP) pesticides: phorate, disulfoton, terbufos, methidathion, bensulide, chlorethoxyfos, phosmet, methyl parathion, phostebupirim, and temephos were evaluated for their potential to undergo oxidation to their respective oxons and/or other oxidation analogues in laboratory water. Samples were collected at time intervals up to 72h of chlorination and analyzed by both gas chromatography-mass selective detection (GC-MSD) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results show that methidathion and methyl parathion were stable in unchlorinated water, while all other OP pesticides were not stable over the 72h exposure period. In chlorinated water, phorate and disulfoton formed stable sulfone oxons. Temephos formed stable dioxon sulfoxide and dioxon sulfone. Methidathion, bensulide, chlorethyoxyfos, methyl parathion, and phostebupirim formed stable oxons over the 72h exposure period. Terbufos, phorate, disulfoton and temephos oxon sulfoxides; temephos sulfoxide; and phosmet oxon were initially formed but were not detected after 24h. The data illustrate that organothiophosphate pesticides may form oxons and/or other oxidation analogues during chlorination in water treatment plants, which are persistent for at least 72h.

AN - 66813807; 19000753 AB - Air pollution epidemiology has established a strong association between exposure to ambient particulate matter (PM) and cardiovascular outcomes. Experimental studies in both humans and laboratory animals support varied biological mechanisms including endothelial dysfunction as potentially a central step to the elicitation of cardiovascular events. We therefore hypothesized that relevant early molecular alterations on endothelial cells should be assessable in vitro upon acute exposure to PM components previously shown to be involved in health outcomes. Using a model emission PM, residual oil fly ash and one of its predominant constituents (vanadium-V), we focused on the development of gene expression profiles to fingerprint that particle and its constituents to explore potential biomarkers for PM-induced endothelial dysfunction. Here we present differential gene expression and transcription factor activation profiles in human vascular endothelial cells exposed to a non-cytotoxic dose of fly ash or V following semi-global gene expression profiling of approximately 8000 genes. Both fly ash and it's prime constituent, V, induced alterations in genes involved in passive and active transport of solutes across the membrane; voltage-dependent ion pumps; induction of extracellular matrix proteins and adhesion molecules; and activation of numerous kinases involved in signal transduction pathways. These preliminary data suggest that cardiovascular effects associated with exposure to PM may be mediated by perturbations in endothelial cell permeability, membrane integrity; and ultimately endothelial dysfunction.

New England community drinking water supply systems that are non-compliant with the drinking water Maximum Contaminant Levels (MCLs) for these contaminants often have concentrations slightly above the MCL. For example, the arsenic MCL is 10 parts per billion (ppb), and most systems with an arsenic problem have concentrations between 10 and 20 ppb. The goal of a project currently underway is to develop cost-effective methods to improve the quality of water produced by an affected well by evaluating whether various transmissive fractures or fracture zones contributing water to a borehole may produce variable concentrations of contaminants (e.g., arsenic, uranium, radium). The methods to be developed will include a process for characterizing the vertical distribution of naturally occurring contaminants entering a borehole and various methods for mitigating the effects of contaminated water inflow, while preserving the water-producing integrity of the well. Methods for mitigating the effects of contaminated water inflow may include sealing fractures, hydro-fracturing, and/or drilling. Strategies for reducing contaminant inflow through pump cycling will also be explored. Contamination mitigation at one well resulted in a decrease in the arsenic concentration of the bulk discharge water, implying that compliance with the arsenic standard via borehole modification in lieu of treatment may be a feasible alternative for public water supply managers. Findings from ongoing and recently completed work will be presented. This is a collaborative project between New Hampshire Dep. of Environmental Services, U.S. Environmental Protection Agency Region 1, and the U.S. Geological Survey.

Terrigenous sediment loadings calculated for different parts of Coral Bay reflect a dramatic increase over the past century. The majority of terrigenous sediments entering Coral Bay are discharged through two main tributaries (guts) and are deposited in the innermost bay with little being deposited seaward. Data show that terrigenous sediment loadings into Coral Harbor have increased by approximately 5x since about 1930, with the most dramatic increase starting around 1960. Relative terrigenous sediment loadings from each tributary have varied since the mid 1940's likely in response to changes in anthropogenic activities. The dramatic rate increase seen in the Coral Bay data in 1960 through the late 1990's is likely to have had its beginnings in the 1960s from the construction of a major road, which crosses many of the major guts draining the north half of the Coral Bay watershed, altering natural drainage patterns, increasing the area of denuded slopes and providing an erodible surface for runoff. Additionally, all sites show a considerable increase in sedimentation since approximately 2000, which is likely due to construction of high-end, large-scale houses, villas and condo's since 2000.

Under Section 312 of the Clean Water Act, a state can petition the Environmental Protection Agency to approve a NDA designation for some or all of its waters. EPA's primary responsibility is to determine whether adequate facilities for the safe and sanitary removal and treatment of sewage from all vessels utilizing the proposed NDA are reasonably available. This designation provides an added layer of water quality protection because it is already illegal to discharge untreated sewage in US waters. Boats equipped with toilets are required to have a Coast Guard-approved Marine Sanitation Device (MSD). MSDs are designed to either hold the raw sewage in a holding tank (Type III) or to treat the sewage and discharge this effluent into the coastal waters (Type I and II). A NDA designation is intended to prevent the discharge of MSD Types I and II within the designated area. (Discharges from Type III MSDs are already prohibited within state waters). Effluent from properly functioning Type I and II MSDs has bacteria concentrations well above water quality standards set for swimming or shellfish harvesting. If the MSD is not properly maintained or operated, concentrations may be even higher. Sewage effluent from MSDs degrades water quality by introducing disease-causing microorganisms, nutrients, and chemicals. During dry weather, sewage discharges from vessels often represent the only possible source of sewage that can cause beaches and shellfish beds to be closed. Maintaining pumpout infrastructure and educating boaters and marina operators are the foundation for the success of any NDA. In fall 2008, an evaluation of the Casco Bay NDA program was performed. At the time of this study, Casco Bay was the only NDA in Maine. The methodology for the evaluation was a multi-method approach utilizing three program evaluation instruments 1) mail-survey of Casco Bay boaters, 2) in-person survey of pumpout facility operators, 3) site visits of the Casco Bay pumpout facilities. Recommendations for the Casco Bay NDA program were made based on the overall research findings. The results from this study can be applicable to NDAs in any area--whether one wants to improve an existing program or to establish a new designation.

There is a continued need for standard analytical methods to accommodate different practices in sample collection, particle size characterization, frequency analysis, and frequency base conversion. We focus upon two related topics: (1) quantitative description of size of irregular particles and (2) frequency base conversion procedures. The first is needed to accurately determine physical particle properties (diameter, surface area, volume, and weight), and the second to determine the statistical influence on one or more of these properties of each particle in a mixture. We collected natural streambed particles, measured various calipered diameters including a nominal diameter using each particle volume, and calculated a shape factor for each diameter that converts it to an equivalent sieved diameter. Next, we extended a model originally derived in 1929 for a lognormal distribution to a streambed particle size distribution that severely deviated from a lognormal distribution. After successfully converting from number to weight frequency (and the reverse) of samples collected by grid, area, and volume, we extended the conversion to apply across these collection methods. These results make streambed frequency analysis independent of the particular diameter used, the observed frequency base, and the sample collection procedure. The immediate utility of our analysis is to facilitate data sharing among disciplines. The ultimate benefit is to free researchers to select the most convenient diameter measurement, size frequency classification, frequency base, and sample collection procedure from the many alternative strategies available.

Results from the testing showed that some stoves currently used in the field have improved fuel efficiency and lower pollutant emissions compared with traditional cooking methods. Stoves with smaller-mass components exposed to the heat of fuel combustion tended to take lesser time to boil, have better fuel efficiency, and lower pollutant emissions. The challenge is to design stoves with smaller-mass components that also have acceptable durability, affordable cost, and meet user needs. Results from this study provide stove performance and emissions information to practitioners disseminating stove technology in the field. This information may be useful for improving the design of existing stoves and for developing new stove designs. Comparison of results between laboratories shows that results can be replicated between labs when the same stove and fuel are tested using the WBT protocol.

To explore the effectiveness of this restoration technique, we measured the d super(15)N of juvenile coho salmon (Oncorhynchus kisutch) as an index of the incorporation of salmon-derived nutrients (SDN) in streams with varying amounts of natural spawners and artificially placed carcasses. Although d super(15)N of juvenile coho salmon increased with salmon carcass mass in the stream channel, this relationship was only significant for natural spawners. Artificially placed carcasses did not appear to increase SDN utilization by juvenile coho salmon. Possible explanatory factors include the restricted spatial and temporal distribution of carcasses, general absence of eggs, and lack of substrate bioturbation associated with artificially placed carcasses. Our study suggests that artificially placed carcasses at the levels added in the Oregon Coast Range may not directly mimic the role of natural spawners in stream foodwebs.

C. Davis) Gert Hansen and Moestrup are influenced by its ability to use ambient light and nutrients for growth and reproduction. This study investigated changes in K. brevis toxicity, lipid class, and carotenoid concentrations in low-light, nitrate-replete (250kmol quanta. m-2. s-1, 80kM NO3); high-light, nitrate-replete (960kmol quanta. m-2.s-1, 80kM NO3); and high-light, nitrate-reduced (960kmol quanta. m-2.s-1, <5kM NO3) mesocosms. Reverse-phase HPLC quantified the epoxidation state (EPS) of the xanthophyll-cycle pigments diadinoxanthin and diatoxanthin, and a Chromarod Iatroscan thin layer chromatography/flame ionization detection (TLC/FID) system quantified changes in lipid class concentrations. EPS did not exceed 0.20 in the low-light mesocosm, but increased to 0.65 in the high-light mesocosms. Triacylglycerol and monogalactosyldiacylglycerol (MGDG) were the largest lipid classes consisting of 9.3% to 48.7% and 37.3% to 69.7% of total lipid, respectively. Both lipid classes also experienced the greatest concentration changes in high-light experiments. K. brevis increased EPS and toxin concentrations while decreasing its lipid concentrations under high light. K. brevis may mobilize its toxins into the surrounding environment by reducing lipid concentrations, such as sterols, limiting competition, or toxins are released because lipids are decreased in high light, reducing any protective mechanism against their own toxins.

We evaluated the differences between TIA and DCIA in the Shepherd Creek catchment, a small (1.85-km super(2)), suburban basin in Cincinnati, Ohio. Imperviousness determinations were calculated based on publicly available geographic information system (GIS) data and parcel-scale field assessments, and these direct assessments were compared to DCIA calculated from published, empirical relationships. Impervious and semi-impervious area comprised 13.1% of the catchment area, with 56.3% of the impervious area connected. When summarized by subcatchments (0.26-1.85 km super(2)), TIA measured in the field (11-23%) was considerably higher than that calculated from the National Land Cover Data Imperviousness Layer (7-18%). In contrast, TIA calculated based on aerial photos was similar to TIA calculated from field assessments, thus indicating that photo interpretation may be adequate for catchment-scale (>25 ha) TIA determinations. While these GIS data sources can be used to calculate TIA, on-site assessments were necessary to accurately determine DCIA within residential parcels. There was a wide variation in percent connectivity across parcels, and, subsequently, DCIA was not accurately predicted from empirical relationships with TIA. We discuss applications of DCIA data that highlight the importance of parcel-scale field assessments for managing suburban watersheds.

We found through a model re-parameterization that such generalization is only valid when the transformed design matrix is orthonormal, in which case the resulting t-ratios of the full model have a consistent order for the entire system (all reduced models). Otherwise, for practical data sets, t-ratios are all interdependent and subjected to changes in reduced models. Significance of the variables inferred from the full model therefore has no general meaning about the physics of the environmental system. In observation of the restriction of the t-test to a single model and the frequent need for deducing a general comparison of variable significance in environmental research, the significance test for explanatory variables can be conducted by a model selection process with, for example, Mallows' Cp, Akaike's Information Criterion (AIC), or Bayesian Information Criterion (BIC), which are insensitive to the orthonormality of the transformed design matrix, as the selection criterion. Once the parsimonious model is identified, the variables in the parsimonious model can be considered to be significant for the response. This is a general inference about the significance of the explanatory variables, which is consistent for the entire system.

A novel class of sulfate/hydroxyl radical-based homogeneous AOTs (Fe(II)/PS, Fe(II)/PMS, Fe(II)/H sub(2)O sub(2)) was successfully tested for the degradation of series of chlorophenols (4-CP, 2,4-CP, 2,4,6-CP, 2,3,4,5-CP). The major objective of the present study was to evaluate the effectiveness of three representative chelating agents (citrate, ethylenediaminedisuccinate (EDDS), and pyrophosphate) on Fe(II)-mediated activation of three common peroxide (peroxymonosulfate (PMS), persulfate (PS), and hydrogen peroxide (H sub(2)O sub(2))) at neutral pH conditions. Short term (4h) and long term (7 days) experiments were conducted to evaluate the kinetics and longevity of different oxidative systems for 4-chlorophenol degradation. Results showed that each of the iron-chelating agent couple was superior in activating a particular oxidant and consequently for 4-CP degradation. In case of Fe(II)/PMS system, the inorganic chelating agent pyrophosphate showed effective activation of PMS whereas very fast dissociation of PMS was recorded in the case of EDDS without any apparent 4-CP degradation. In Fe(II)/H sub(2)O sub(2) system, EDDS was proven to be the most effective whereas pyrophosphate showed negligible activation of H sub(2)O sub(2). Fe(II)/Citrate system showed moderate activation of all three oxidants. PMS was found to be the most universal oxidant, which was activated by all three iron-chelating agent systems and Fe(II) /Citrate was the most universal chelating agent system, which was able to activate all three oxidants to a certain extent.

However, we show that extreme droughts (less than two-thirds expected rainfall over 3 years) occur in the drier half of the savanna biome and can cause substantial tree death. An Australian case study reveals that a net increase in tree cover over five decades of above-average rainfall was offset by sudden tree death during drought. The relationship between woody cover change and rainfall is moderated by competition with growth being facilitated by low woody cover and drought-induced death more likely as the woody component of savanna increases. The results are not supportive of a sustained increase in the woody component of xeric savannas resulting from CO2 fertilization or land management. Extensive tree death in savanna regions will become a stark consequence of climate change if predictions of increasing severity and frequency of drought are realized.

While such techniques may be adequate for some applications, conclusions are limited by such factors as the sparseness of the available observations (limiting the number of grid cells at which the model can be evaluated) and the incommensurability between volume-averages and pointwise observations. We examine several sets of simulations to illustrate the effect of incommensurability in a variety of cases distinguished by the type and extent of spatial correlation present. Block kriging, a statistical method which can be used to address the issue, is then demonstrated using the simulations.

During summertime in Raleigh, North Carolina, UFPs were simultaneously measured upwind and downwind of a major roadway using a spatial matrix of five portable industrial hygiene samplers (measuring total counts of 20-1000nm particles). While the upper sampling range of the portable samplers extends past the defined ''ultrafine'' upper limit (100nm), the 20-1000nm number counts had high correlation (Pearson R=0.7-0.9) with UFPs (10-70nm) measured by a co-located research-grade analyzer and thus appear to be driven by the ultrafine range. Highest UFP concentrations were observed during weekday morning work commutes, with levels at 20m downwind from the road nearly fivefold higher than at an upwind station. A strong downwind spatial gradient was observed, linearly approximated over the first 100m as an 8% drop in UFP counts per 10m distance. This result agreed well with UFP spatial gradients estimated from past studies (ranging 5-12% drop per 10m). Linear regression of other vehicle-related air pollutants measured in near real-time (10-min averages) against UFPs yielded moderate to high correlation with benzene (R super(2)=0.76), toluene (R super(2)=0.49), carbon monoxide (R super(2)=0.74), nitric oxide (R super(2)=0.80), and black carbon (R super(2)=0.65). Overall, these results support the notion that near-road levels of UFPs are heavily influenced by traffic emissions and correlate with other vehicle-produced pollutants, including certain air toxics.

In this study, organic and elemental carbon (OC and EC) within ambient PM sub(2) sub(.) sub(5) over a three-year period at a forested site in the North Carolina Piedmont are presented. EC exhibited significant weekday/weekend effects and less significant seasonal effects, in contrast to OC, which showed strong seasonal differences and smaller weekend/weekday effects. Summer OC concentrations are about twice as high as winter concentrations, while EC was somewhat higher in the winter. OC was highly correlated with EC during cool periods when both were controlled by primary combustion sources. This correlation decreased with increasing temperature, reflecting higher contributions from secondary organic aerosol, likely of biogenic origin. PM sub(2) sub(.) sub(5) radiocarbon data from the site confirms that a large fraction of the carbon in PM sub(2) sub(.) sub(5) is indeed of biogenic origin, since modern (non-fossil fuel derived) carbon accounted for 80% of the PM sub(2) sub(.) sub(5) carbon over the course of a year. OC and EC exhibited distinct diurnal profiles, with summertime OC peaking in late evening and declining until midday. During winter, OC peaked during the early morning hours and again declined until midday. Summertime EC peaked during late morning hours except on weekends. Wintertime EC often peaked in late PM or early AM hours due to local residential wood combustion emissions. The highest short term peaks in OC and EC were associated with wildfire events. These data corroborate recent source apportionment studies conducted within 20km of our site, where oxidation products of isoprene, a-pinene, and b-caryophyllene were identified as important precursors to organic aerosols. A large fraction of the carbon in rural southeastern ambient PM sub(2) sub(.) sub(5) appears to be of biogenic origin, which is probably difficult to reduce by anthropogenic controls.

One of the EMAs was located near a busy freeway (annual average daily traffic (AADT) of ~130,000) so that impacts of mobile sources could be examined. Air pollution concentrations from the roadway-proximate sites were compared to the central site monitor. The volatile organic compounds (VOCs) selected (benzene, toluene, ethylbenzene, m,p- and o-xylene, 1,3 butadiene, 1,3,5-trimethylbenzene and 4-ethyltoluene) are typically associated with mobile sources. Gradients were also evident that demonstrated the amplification of pollutant levels near the roadway compared to the community monitor. A novel distance-to-roadway proximity metric was developed to plot the measurements and model these gradients. Effective distance represents the actual distance an air parcel travels from the middle of a roadway to a site and varies as a function of wind direction, whereas perpendicular distance is a fixed distance oriented normal to the roadway. Perpendicular distance is often used as a proxy for exposures to traffic emissions in epidemiological studies. Elevated concentrations of all the compounds were found for both a summer and winter season. Effective distance was found to be a statistically significant (p<0.05) univariate predictor for concentrations of toluene, ethylbenzene, m,p-xylene and o-xylene for summer 2005. For each of these pollutants, effective distance yielded lower p-values than the corresponding perpendicular distance models, and model fit improved. Results demonstrate that this near-road EMA had elevated levels of traffic-related VOCs compared to the community monitor, and that effective distance was a more accurate predictor of the degree to which they were elevated as a function of distance. Effective distance produced a range of distance-to-roadway values for a single site based on wind direction, thus increasing the number and range of values that could be used to plot and predict relative differences in pollutant concentrations between two sites.

8879103 AB - Aromatase is a steroidogenic enzyme that catalyzes the conversion of androgens to estrogens in vertebrates. Modulation of this enzyme's activity by xenobiotic exposure has been shown to adversely affect gonad differentiation in a number of diverse species. We hypothesized that exposure to the aromatase inhibitor, fadrozole, during the larval development of the tropical clawed frog, Xenopus tropicalis, would result in masculinization of the developing female gonad. Tadpoles were exposed to fadrozole at nominal concentrations from 1 to 64kg/L in a flow-through system from <24h post-fertilization (Nieuwkoop Faber (NF) stage 15-20) to metamorphosis (NF stage 66). At metamorphosis, morphologically examined gonads indicated complete masculinization of all tadpoles at concentrations of 16kg/L and above and a significant bias in sex ratio towards males at concentrations of 1kg/L and above. No effects on time to metamorphosis, body mass, or body length were observed. A random subsample of frogs was raised to reproductive maturity (39 weeks post-fertilization) in control water. All frogs exposed as tadpoles to 16kg/L fadrozole or greater possessed testes at sexual maturity. Intersexed gonads characterized by the presence of both testicular and ovarian tissue were observed in 12% of frogs in the 4kg/L treatment. No differences in estradiol, testosterone, or vitellogenin plasma concentrations were observed in exposed males or females compared to controls. Females in the 4kg/L treatment possessed a significantly greater percentage of pre-vitellogenic oocytes than controls and were significantly smaller in body mass. No differences in sperm counts were observed in exposed males compared to controls. Results from this study demonstrate that larval exposure to an aromatase inhibitor can result in the complete masculinization of female gonads. These masculinized females are phenotypically indistinguishable from normal males at adulthood. Lower levels of aromatase inhibition resulted in intersexed gonads and possible female reproductive impairment at adulthood. These results indicate that exposure of amphibians to xenobiotics capable of inhibiting aromatase would result in adverse reproductive consequences.

Estrogen receptors representing five vertebrate classes were compared: human estrogen receptor alpha (hERa), quail estrogen receptor alpha (qERa), alligator estrogen receptor alpha (aERa), salamander estrogen receptor alpha (sERa), and fathead minnow estrogen receptor alpha (fhERa). Saturation binding analyses indicated 17b-estradiol (E2) dissociation constants (Kd) were 0.22+/-0.02nM for hERa, 0.28+ /-0.04nM for sERa, 0.44+/-0.04nM for aERa, 0.58+/-0.10nM for qERa, and 0.58+/-0.05nM for fhERa. Binding specificity to each of the receptors was evaluated using E2, dihydrotestosterone (DHT), corticosterone (C), and ethinylestradiol (EE). E2 and EE were strong binders in all species with IC50's ranging from 0.65nM with hERa to 1.01nM with sERa for E2 and from 0.68nM with sERa to 1.20nM with qERa for EE. DHT was a weak binder with IC50's ranging from 3.3kM with hERa to 39kM with fhERa, and C did not bind any of the receptors at concentrations up to 100kM. This system provides a convenient in vitro approach for directly comparing chemical binding to estrogen receptors across multiple species without the need to sacrifice animals.

It is increasingly used for the disinfection of homes and other indoor environments afflicted by mold. However, little is known regarding the interaction of chlorine dioxide and indoor materials, particularly as related to the removal of chlorine dioxide from air. Such removal may be undesirable with respect to the subsequent formation of localized zones of depleted disinfectant concentrations and potential reductions in disinfection effectiveness in a building. The focus of this paper is on chlorine dioxide removal from air to each of 24 different indoor materials. Experiments were completed with materials housed in flow-through 48-L stainless steel chambers under standard conditions of 700 ppm chlorine dioxide inlet concentration, 75% relative humidity, 24 C, and 0.5 h-1 air changes. Chlorine dioxide concentration profiles, deposition velocities, and reaction probabilities are described in this paper. Deposition velocities and reaction probabilities varied over approximately 2 orders of magnitude across all materials. For most materials, deposition velocity decreased significantly over a 16-h disinfection period; that is, materials became smaller sinks for chlorine dioxide with time. Four materials (office partition, ceiling tile, medium density fiberboard, and gypsum wallboard) accounted for the most short- and long-term consumption of chlorine dioxide. Deposition velocity was observed to be a strong function of chlorine dioxide inlet concentration, suggesting the potential importance of chemical reactions on or within test materials.

Limiting factors in MTBE removal in GAC include the heterogeneous distribution of amended Fe, and slow intraparticle diffusive transport of MTBE and hydrogen peroxide (H2O2) into the 'reactive zone'. Acid pretreatment of GAC before Fe amendment altered the surface chemistry of the GAC, lowered the pH point of zero charge, and resulted in greater penetration and more uniform distribution of Fe in GAC. This led to a condition where Fe, MTBE, and H2O2 coexisted over a larger volume of the GAC contributing to greater MTBE oxidation and removal. H2O2 reaction and MTBE removal in GAC increased with temperature. Modeling H2O2 transport and reaction in GAC indicated that H2O2 penetration was inversely proportional with temperature and tortuosity, and occurred over a larger fraction of the total volume of small GAC particles (0.3 mm diameter) relative to large particles (1.2 mm diameter). Acidic pretreatment of GAC, Fe-amendment, elevated reaction temperature, and use of small GAC particles are operational parameters that improve Fenton-driven oxidation of MTBE in GAC.

The fundamental kinetic data is critical for the accurate evaluation of hydroxyl-radical based technologies for the destruction of this problematic class of cyanotoxins. The bimolecular rate constant for the reaction of hydroxyl radical with MC-LR is 2.3 (c0.1) X 1010 M-1s-1 based on time-resolved competition kinetics with SCN- at low conversions using pulsed radiolysis experiments. The reaction of hydroxyl radical with MC-LR can occur via a number of competing reaction pathways, including addition to the benzene ring and diene and abstraction of aliphatic hydrogen atoms. LC-MS analyses indicate the major products from the reaction of hydroxyl radicals with MC-LR involve addition of hydroxyl radical to the benzene ring and diene moieties of the Adda side chain. Transient absorption spectroscopy monitored between 260-500 nm, following pulsed hydroxyl radical generation, indicate the formation of a transient species with absorption maxima at 270 and 310 nm. The absorption maxima and lifetime of the transient species are characteristic of hydroxycyclohexadienyl radicals resulting from the addition of hydroxyl radical to the benzene ring. The rate constant for the formation of hydroxycyclohexadienyl radical is 1.0 (c0.1) X 1010 M-1s-1 accounting for 40% of the primary reaction pathways. Representative rate constants and partitioning of hydroxyl radical reactions were assessed based on the reactivities of surrogate substrates and individual amino acids. Summation of the individual reactivities of hydroxyl radical at the different reactive sites (amino acids) leads to a rate constant of 2.1 X 1010 M-1 s-1 in good agreement with the rate constant determined in our studies. The relative magnitude of the rate constants for the reactions of hydroxyl radical with the individual amino acids and appropriate surrogates, suggest 60-70% reactions of hydroxyl radical occur at the benzene and diene functional groups of the Adda moiety.

The sites included an urban site (Chicago, Illinois) and three rural/remote sites (Eagle Harbor, Michigan; Sleeping Bear Dunes, Michigan; and Sturgeon Point, New York). Sampling occurred every 24 days between November 2004 and December 2007. The concentration of PCDD/Fs averaged 2.3 plus or minus 0.2 fg WHO TEQ/m super(3) at Eagle Harbor, 35 plus or minus 3 fg WHO TEQ/m super(3) at Chicago, 7.4 plus or minus 1.4 fg WHO TEQ/m super(3) at Sleeping Bear Dunes, and 13 plus or minus 2 fg WHO TEQ/m super(3) at Sturgeon Point. The total concentration of the 17 toxic PCDD/F congeners showed a significant seasonal trend at all sites, except Chicago. The date of maximum concentration averaged Dec 6 plus or minus 35 days, which is consistent with residential heating being an important source of PCDD/Fs to the atmosphere. A significant positive relationship between the logarithm of the total concentration of the 17 toxic PCDD/F congeners and the logarithm of the number of people within a 25 km radius around the sampling site was found. We suggest that urban and industrial areas, which are heavily populated, act as sources of PCDDs and PCDFs to the atmosphere.

The wavelet transform of E. coli concentration and its explanatory variables observed at Huntington Beach, Ohio in 2006 exhibited well-defined patterns of different time scales, phases, and durations, which cannot be clearly shown in conventional time-domain analyses. If linear regression modeling is to be used for the ease of implementation and interpretation, the wavelet-transformed regression model reveals that low model residual can be realized through matching major patterns and their phase angles between E. coli concentration and its explanatory variables. The property of pattern matching for linear regression models can be adopted as a criterion for choosing useful predictors, while phase matching further explains why intuitively good variables such as wave height and onshore wind speed were excluded from the optimal models by model selection processes in Frick et al. (Environ. Sci. Technol. 2008, 42, 4818-4824). The phase angles defined by the wavelet analysis in the time-frequency domain can help identify the physical processes and interactions occurring between bacteria concentration and its explanatory variables. It was deduced, for this particular case, that wind events resulted in elevated E. coli concentration, wave height, and turbidity at the beach with a periodicity of 7-8 days. Wind events also brought about increased beach bacteria concentrations through large-scale current circulations in the lake with a period of 21 days. The time length for linear regression models with statistical robustness can also be deduced from the periods of the major patterns in bacteria concentration and explanatory variables, which explains and supplements the modeling efforts performed in (1).

AN - 66959318; 19238960 AB - Colloidal suspensions of C60, C70, and a derivative of C60, PCBM ([6,6]-Phenyl C61-butyric acid methyl ester)were produced by extended mixing in water. We examined the contribution of background solution chemistry (pH, ionic strength) on the formation of colloidal suspensions in terms of mass, aggregate size, and zeta potential. These parameters were also compared between free-settling and filtered treatments. Results indicated that all three fullerenes were highly negatively charged in aqueous systems, that it took a finite time to reach kinetically stable suspensions, and that suspension formation was pH and ionic strength dependent. With isoelectric points approaching zero, the suspensions were generally stable at pH > 3. The results indicate that it is critical to state the condition under which the formation of aqueous fullerene suspensions occurs when employing such suspensions to evaluate environmental toxicity or fate and transport of fullerenes.

AN - 66809502; 19027014 AB - The tropical clawed frog, Xenopus tropicalis, is a relatively new model species being used in developmental biology and amphibian toxicology studies. In order to increase our understanding of reproductive maturation and the role of steroid hormones in X. tropicalis, we collected baseline reproductive data in this species from metamorphosis to adulthood. One cohort of frogs was maintained for 42 weeks post-metamorphosis (PM) with endpoints representative of important reproductive parameters collected at 1- or 2-week intervals. These endpoints were then correlated to titers of either estradiol or testosterone. Male frogs exhibited nuptial pads, starting at 8 weeks (PM) when measureable concentrations of circulating testosterone (5.3 ng/mL plasma) first appeared. Testosterone concentrations remained above this level at all later time points, but were highly variable among individuals. Testes sizes in males reached their peak at 22 weeks PM (21 mg) with sperm counts peaking at the same time (25 million sperm/male). In females, estradiol becomes elevated in the blood at 16 weeks PM (1.5 ng/mL plasma) which corresponds with the presences of vitellogenin (4.4 mg/mL plasma), vitellogenic oocytes in the ovary, ovarian growth, and oviduct growth. Vitellogenic oocytes increased in number up to 15,000 per female at 30 weeks PM and accounted for 75% of the total number of oocytes present in the ovary. The ovary and oviducts continued to grow in mass until 30 weeks PM at which point they had reached sizes of 3.6g and 0.8 g, respectively. These data indicate that male and female X. tropicalis reach reproductive maturation at 22 and 30 weeks PM, respectively. Results from this study are valuable for the design of amphibian toxicology assays and increase our understanding of the reproductive biology of this relatively new model species.

In order to expedite the screening process, there is a need to identify alternative toxicity measures that may be used as surrogates for carcinogenic potency. Alternative toxicity measures for carcinogenic potency currently being used in the literature include lethal dose (dose that kills 50% of a study population [LD sub(5) sub(0)]), lowest-observed-adverse-effect-level (LOAEL) and maximum tolerated dose (MTD). The purpose of this study was to investigate the correlation between tumor dose (TD sub(5) sub(0)) and three alternative toxicity measures as an estimator of carcinogenic potency. A second aim of this study was to develop a Classification and Regression Tree (CART) between TD sub(5) sub(0) and estimated /experimental predictor variables to predict the carcinogenic potency of new chemicals. Rat TD sub(5) sub(0)s of 590 structurally diverse chemicals were obtained from the Cancer Potency Database, and the three alternative toxicity measures considered in this study were estimated using TOPKAT super(()R), a toxicity estimation software. Though poor correlations were obtained between carcinogenic potency and the three alternative toxicity (both experimental and TOPKAT) measures for the CPDB chemicals, a CART developed using experimental data with no missing values as predictor variables provided reasonable estimates of TD sub(5) sub(0) for nine chemicals that were part of an external validation set. However, if experimental values for the three alternative measures, mutagenicity and logP are not available in the literature, then either the CART developed using missing experimental values or estimated values may be used for making a prediction.

In a previous toxicogenomic study of triazole-containing conazoles we found gene expression changes consistent with the alteration of the metabolism of all trans-retinoic acid (atRA), a vitamin A metabolite with cancer-preventative properties (Ward et al., Toxicol. Pathol. 2006; 34:863-78). The goals of this study were to examine effects of propiconazole, triadimefon, and myclobutanil, three triazole-containing conazoles, on the microsomal metabolism of atRA, the associated hepatic cytochrome P450 (P450) enzyme(s) involved in atRA metabolism, and their effects on hepatic atRA levels in vivo. The in vitro metabolism of atRA was quantitatively measured in liver microsomes from male CD-1 mice following four daily intraperitoneal injections of propiconazole (210 mg/kg/d), triadimefon (257 mg/kg/d) or myclobutanil (270 mg/kg/d). The formation of both 4-hydroxy-atRA and 4-oxo-atRA were significantly increased by all three conazoles. Propiconazole-induced microsomes possessed slightly greater metabolizing activities compared to myclobutanil-induced microsomes. Both propiconazole and triadimefon treatment induced greater formation of 4-hydroxy-atRA compared to myclobutanil treatment. Chemical and immuno-inhibition metabolism studies suggested that Cyp26a1, Cyp2b, and Cyp3a, but not Cyp1a1 proteins were involved in atRA metabolism. Cyp2b10/20 and Cyp3a11 genes were significantly over-expressed in the livers of both triadimefon- and propiconazole-treated mice while Cyp26a1, Cyp2c65 and Cyp1a2 genes were over-expressed in the livers of either triadimefon- or propiconazole-treated mice, and Cyp2b10/20 and Cyp3a13 genes were over-expressed in the livers of myclobutanil-treated mice. Western blot analyses indicated conazole induced-increases in Cyp2b and Cyp3a proteins. All three conazoles decreased hepatic atRA tissue levels ranging from 45-67%. The possible implications of these changes in hepatic atRA levels on cell proliferation in the mouse tumorigenesis process are discussed.

In this study, transfer was evaluated as a function of the moisture and fat content of various foods. Surfaces chosen for investigation were those commonly found in homes and included Formica super( registered ), ceramic tile, plastic, carpet, and upholstery fabric. Each surface type was sprayed with an aqueous emulsion of organophosphates, fipronil, and synthetic pyrethroids. In the first phase of the study, multiple foods (apples, watermelon, wheat crackers, graham crackers, white bread, flour tortillas, bologna, fat-free bologna, sugar cookies, ham, Fruit Roll-ups super( registered ), pancakes, and processed American cheese) were categorized with respect to moisture and fat content. All were evaluated for potential removal of applied pesticides from a Formica surface. In the second phase of the study, representative foods from each classification were investigated for their potential for pesticide transfer with an additional four surfaces: ceramic tile, plastic, upholstery, and carpet. Moisture content, not fat, was found to be a determining factor in most transfers. For nearly all surfaces, more efficient transfer occurred with increased hardness (Formica and ceramic tile). Comparatively, the polymer composition of the plastic delivered overall lower transfer efficiencies, presumably due to an attraction between it and the organic pesticides of interest.Journal of Exposure Science and Environmental Epidemiology (2009) 19, 97-106; doi:10.1038/jes.2008.6; published online 16 April 2008 JF - Journal of Exposure Science and Environmental Epidemiology AU - Vonderheide, Anne P AU - Bernard, Craig E AU - Hieber, Thomas E AU - Kauffman, Peter E AU - Morgan, Jeffrey N AU - Melnyk, Lisa Jo AD - aUnited States Environmental Protection Agency, Office of Research and Development, National Exposure Research Laboratory, Microbiological and Chemical Exposure Assessment Research Division, Chemical Exposure Research Branch, Cincinnati, Ohio 45268, USA Y1 - 2009/01// PY - 2009 DA - Jan 2009 SP - 97 EP - 106 PB - Nature Publishing Group, The Macmillan Building London N1 9XW UK VL - 19 IS - 1 SN - 1559-0631, 1559-0631 KW - Entomology Abstracts; Toxicology Abstracts KW - Formica KW - Sugar KW - Food KW - Children KW - Ceramics KW - Triticum aestivum KW - Epidemiology KW - Carpets KW - fipronil KW - Pesticides KW - Citrullus lanatus KW - Plastics KW - Z 05300:General UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/877595516?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Atoxicologyabstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.atitle=Surface-to-food+pesticide+transfer+as+a+function+of+moisture+and+fat+content&rft.au=Vonderheide%2C+Anne+P%3BBernard%2C+Craig+E%3BHieber%2C+Thomas+E%3BKauffman%2C+Peter+E%3BMorgan%2C+Jeffrey+N%3BMelnyk%2C+Lisa+Jo&rft.aulast=Vonderheide&rft.aufirst=Anne&rft.date=2009-01-01&rft.volume=19&rft.issue=1&rft.spage=97&rft.isbn=&rft.btitle=&rft.title=Journal+of+Exposure+Science+and+Environmental+Epidemiology&rft.issn=15590631&rft_id=info:doi/10.1038%2Fjes.2008.6 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2010-10-01 N1 - Last updated - 2011-12-14 N1 - SubjectsTermNotLitGenreText - Ceramics; Sugar; Epidemiology; fipronil; Carpets; Food; Pesticides; Plastics; Children; Triticum aestivum; Formica; Citrullus lanatus DO - http://dx.doi.org/10.1038/jes.2008.6 ER - TY - JOUR T1 - Microbial-induced heterogeneity in the acoustic properties of porous media AN - 762682811; 2010-094194 AB - It is not known how biofilms affect seismic wave propagation in porous media. Such knowledge is critical for assessing the utility of seismic techniques for imaging biofilm development and their effects in field settings. Acoustic wave data were acquired over a two-dimensional region of a microbial-stimulated sand column and an unstimulated sand column. The acoustic signals from the unstimulated column were relatively uniform over the 2D scan region. The data from the microbial-stimulated column exhibited a high degree of spatial heterogeneity in the acoustic wave amplitude, with some regions exhibiting significant increases in attenuation while others exhibited decreases. Environmental scanning electron microscopy showed differences in the structure of the biofilm between regions of increased and decreased acoustic wave amplitude. We conclude from these observations that variations in microbial growth and biofilm structure cause heterogeneity in the elastic properties of porous media with implications for the validation of bioclogging models.

Green jobs are no longer a concept, they are a reality and they are vital to economic growth and a driver for economic recovery. Environmental issues will be swept up as we address the economy. The choices will never be between one green or the other. And labor must be a partner in this effort. Adapted from the source document.

Sampling regimens that do not characterize diel variations in water quality can result in an inaccurate understanding of site conditions and of the threat posed by the site to human health and the environment. Surface- and groundwater affected by acid drainage were sampled every 60 to 90 minutes over a 48-hour period at a former zinc smelter known as the Hegeler Zinc Superfund Site, in Hegeler, Ill. Groundwater-quality data from a well at the site indicate stable, low pH, weakly oxidizing geochemical conditions in the aquifer. With the exceptions of temperature and pH, no constituents exhibited diel variations in groundwater. Variations in temperature and pH likely were not representative of conditions in the aquifer. Surface water was sampled at a site on Grape Creek. Diel variations were observed in temperature, dissolved oxygen, pH, and specific conductance, and in the concentrations of nitrite, barium, iron, lead, vanadium, and possibly uranium. Concentrations during the diel cycles varied by about an order of magnitude for nitrite and varied by about a factor of two for barium, iron, lead, vanadium, and uranium. Temperature, dissolved oxygen, specific conductance, nitrite, barium, lead, and uranium generally reached maximum values during the afternoon and minimum values during the night. Iron, vanadium, and pH generally reached minimum values during the afternoon and maximum values during the night. These variations would need to be accounted for during sampling of surface-water quality in similar hydrologic settings. The temperature variations in surface water were affected by variations in air temperature. Concentrations of dissolved oxygen were affected by variations in the intensity of photosynthetic activity and respiration. Nitrite likely was formed by the oxidation of ammonium by dissolved oxygen and degraded by its anaerobic oxidation by ammonium or as part of the decomposition of organic matter. Variations in pH were affected by the photoreduction of Fe (super 3+) to Fe (super 2+) and the precipitation of iron oxyhydroxides. Diel variations in concentrations of iron and vanadium were likely caused by variations in the dissolution and precipitation of iron oxyhydroxides, oxyhydroxysulfates, and hydrous sulfates, which may have been affected by in the intensity of insolation, iron photoreduction, and the concentration of dissolved oxygen. The concentrations of lead, uranium, and perhaps barium in Grape Creek may have been affected by competition for sorption sites on iron oxyhydroxides. Competition for sorption sites was likely affected by variations in pH and the concentration of Fe (super 2+) . Constituent concentrations likely also were affected by precipitation and dissolution of minerals that are sensitive to changes in pH, temperature, oxidation-reduction conditions, and biologic activity. The chemical and biologic processes that resulted in the diel variations observed in Grape Creek occurred within the surface-water column or in the underlying sediments.

Remote sensing has long been used to effectively monitor chlorophyll concentrations in open ocean systems; however, operational monitoring in coastal and estuarine areas has been limited because of the inherent complexities of coastal systems, and the coarse spectral and spatial resolutions of available satellite systems. Data were collected using the National Aeronautics and Space Administration (NASA) Advanced Visible-Infrared Imaging Spectrometer (AVIRIS) flown at an altitude of approximately 20 000 m to provide hyperspectral imagery and simulate both MEdium Resolution Imaging Spectrometer (MERIS) and Moderate Resolution Imaging Spectrometer (MODIS) data. AVIRIS data were atmospherically corrected using a radiative transfer modelling approach and analysed using band ratio and linear regression models. Regression analysis was performed with simultaneous field measurements data in the Neuse River Estuary (NRE) and Pamlico Sound on 15 May 2002. Chlorophyll a (Chl a) concentrations were optimally estimated using AVIRIS bands (9.5 nm) centred at 673.6 and 692.7 nm, resulting in a coefficient of determination (R 2) of 0.98. Concentrations of Chromophoric Dissolved Organic Matter (CDOM), Total Suspended Solids (TSS) and Fixed Suspended Solids (FSS) were also estimated, resulting in coefficients of determination of R 2 = 0.90, 0.59 and 0.64, respectively. Ratios of AVIRIS bands centred at or near those corresponding to the MERIS and MODIS sensors indicated that relatively good satellite-based estimates could potentially be derived for water colour constituents at a spatial resolution of 300 and 500 m, respectively.

The first set created prototype particles from complete and partial combustion, or oxygen free pyrolysis of a high iron Illinois bituminous coal in an externally heated drop-tube furnace. The second experiment created prototype particles consisting of iron and soot in various concentrations from doped ethylene Burke-Schumann flames. Size-classified samples from the coal tests were separated into coarse (>2.5km), fine (0.5-2.5km) and ultrafine (<0.5km) fractions, and analyzed for total carbon, elemental composition, and detailed iron and sulfur speciation. In a similar manner, ultrafine particles from the ethylene flame tests were also analyzed for total carbon and elemental composition. Pulmonary inflammatory responses were determined after intratracheal aspiration of 100kg samples in female CD1 mice. IL-6 and neutrophil responses were monitored as markers of inflammation. With carbon present, the coal data suggested that the ultrafine particles containing soot were more toxic than fine or coarse particles containing char, even though the iron and sulfur speciation varied only slightly with particle size. Iron and sulfur chemistry were, however, dependent on the extent of carbon burnout achieved. In the absence of carbon, ultrafine particles (high in bisulfates and semi-volatile alkali metals) were less toxic than the fine fraction (high in oxidized iron and sulfates). Iron-soot particles created from ethylene flames were more toxic than an equivalent physical mixture of iron oxide and soot, and the toxicity depended primarily on the soot concentration. However, taken as whole, these data do not support the notion that iron and soot interact to enhance pulmonary inflammatory responses.

The samples analysed were soil, surface water (Arges River) and underground water (wells). Pesticide residues were found especially in soil samples, in smaller quantities in surface waters and only in small quantities in underground water. The persistency of these chemicals in soil is correlated with the accumulation process effects in crops (were analysed samples of cabbage, radish and tomatoes), which might be hazardous for human health.

The present review summarizes recent developments in MW- assisted synthesis, name reactions and organic transformations, and rapid generation of nanoparticles with uniform size distribution. Greener protocols have been developed for the synthesis of various bio-active heterocycles, namely 1,3,4-oxadiazoles, 1,3,4-thiadiazoles, 1,3-dioxanes, pyrazoles, hydrazones and 3,4-dihydropyrimidin-2(1H)-ones, which proceed under the influence of microwaves and using eco-friendly conditions. These high- yielding methods were catalyzed efficiently by solid-supported Nafion NR50 under solvent-free conditions and polystyrene sulfonic acid in aqueous media. The eco-friendly nucleophilic substitution chemistry in water to generate cyclic amines via double N-alkylation of primary amines or hydrazines by dihalides or tosylates enables the greener synthesis of a range of pharmaceutically active heterocycles. Similarly, efficient MW synthesis of various azides, thiocyanates, and sulfones in aqueous medium occurs wherein nucleophilic substitution reaction takes place in the absence of a phase- transfer catalyst. Bulk and shape-controlled synthesis of noble nanostructures via MW-assisted spontaneous reduction of noble metal salts using a-d-glucose, sucrose, and maltose is described. MW method also accomplishes the cross-linking reaction of poly(vinyl alcohol) with metallic systems such as Pt, Cu, and In; bimetallic systems, namely Pt-In, Ag-Pt, Pt- Fe, Cu-Pd, Pt-Pd, and Pd-Fe; and single-walled nanotubes, multi-walled nanotubes, and buckminsterfullerenes (C-60). The strategy is extended to the formation of biodegradable carboxymethyl cellulose (CMC) composite films with noble nanometals; such metal decoration and alignment of carbon nanotubes in CMC is possible using a MW approach that also enables the shape-controlled bulk synthesis of Ag and Fe nanorods in poly(ethylene glycol).

The purpose of the Superfund program is to protect human health and the environment over the long term from releases or potential releases of hazardous substances from abandoned or uncontrolled hazardous waste sites. This paper provides a brief overview of the approach used by EPA to conduct Superfund cleanups at contaminated sites, including those that are contaminated with radionuclides, to ensure protection of human health and the environment. The paper addresses how EPA Superfund determines if a site poses a risk to human health and the framework used to determine cleanup levels. The theme emphasized throughout the paper is that within the Superfund remediation framework, radioactive contamination is dealt with in a consistent manner as with chemical contamination, except to account for the technical differences between radionuclides and chemicals. This consistency is important since at every radioactively contaminated site being addressed under Superfund's primary program for long-term cleanup, the National Priorities List (NPL), chemical contamination is also present.

This paper describes delineating the boundaries of fine particulate matter (PM sub(2.5)) nonattainment areas by integrating PM ambient data and satellite aerosol optical depth (AOD) with geostatistical kriging. Correlation between the ground and satellites for the three year average was adequate in the upper Midwest and northeast (greater than r = .57) and typically very poor in the rest of the country (less than r = .20). To improve the geospatial prediction of the extent of aerosols, satellite AOD data from the MODerateresolution Imaging Spectroradiometer (MODIS) sensor was used. This addition of daily air quality data aids prediction of air pollution extent, making the approximation of fine particle airsheds possible.

A simplified taxonomy for sources of uncertainty and a glossary of key terms with "standard" definitions are provided in the context of integrated approaches to environmental assessment. These constructs provide a reference point for cataloging 65 different model evaluation tools. Each tool is described briefly (in the auxiliary material) and is categorized for applicability across seven thematic model evaluation methods. Ratings for citation count and software availability are also provided, and a companion Web site containing download links for tool software is introduced. The paper concludes by reviewing strategies for tool interoperability and offers guidance for both practitioners and tool developers.

The NHD is a comprehensive set of digital spatial data that contains information about surface-water features (such as lakes, ponds, streams, and rivers) of the United States. The need for NHD catchments was driven primarily by the goal to estimate NHD streamflow and velocity to support water-quality modeling. The application of catchments for this purpose also demonstrates the broader value of NHD catchments for supporting landscape characterization and analysis. Five catchment delineation methods were evaluated. Four of the methods use topographic information for the delineation of the NHD catchments. These methods include the Raster Seeding Method; two variants of a method first used in a USGS New England study--one used the Watershed Boundary Dataset (WBD) and the other did not--termed the "New England Methods"; and the Outlet Matching Method. For these topographically based methods, the elevation data source was the 30-meter (m) resolution National Elevation Dataset (NED), as this was the highest resolution available for the conterminous United States and Hawaii. The fifth method evaluated, the Thiessen Polygon Method, uses distance to the nearest NHD stream segments to determine catchment boundaries. Catchments were generated using each method for NHD stream segments within six hydrologically and geographically distinct Subbasins to evaluate the applicability of the method across the United States. The five methods were evaluated by comparing the resulting catchments with the boundaries and the computed area measurements available from several verification datasets that were developed independently using manual methods. The results of the evaluation indicated that the two New England Methods provided the most accurate catchment boundaries. The New England Method with the WBD provided the most accurate results. The time and cost to implement and apply these automated methods were also considered in ultimately selecting the methods used to produce NHD catchments for the conterminous United States and Hawaii. This study was conducted by a joint USGS-USEPA team during the 2-year period that ended in September 2004. During the following 2-year period ending in the fall of 2006, the New England Methods were used to produce NHD catchments as part of a multiagency effort to generate the NHD streamflow and velocity estimates for a suite of integrated geospatial products known as "NHDPlus."

Data organization. AN - 734044832; 19743944 AB - The assessment of human cancer risk from chemical exposure requires the integration of diverse types of data. Such data involve effects at the cell and tissue levels. This report focuses on the specific utility of one type of data, namely DNA adducts. Emphasis is placed on the appreciation that such DNA adduct data cannot be used in isolation in the risk assessment process but must be used in an integrated fashion with other information. As emerging technologies provide even more sensitive quantitative measurements of DNA adducts, integration that establishes links between DNA adducts and accepted outcome measures becomes critical for risk assessment. The present report proposes an organizational approach for the assessment of DNA adduct data (e.g., type of adduct, frequency, persistence, type of repair process) in concert with other relevant data, such as dosimetry, toxicity, mutagenicity, genotoxicity, and tumor incidence, to inform characterization of the mode of action. DNA adducts are considered biomarkers of exposure, whereas gene mutations and chromosomal alterations are often biomarkers of early biological effects and also can be bioindicators of the carcinogenic process.

AN - 67687280; 19817702 AB - We tested the postulate that asbestos exposure alters iron homeostasis in the mouse lung. Crocidolite asbestos (100 microg intratracheally) was instilled into C57BL/6 mice. TiO2 served as a control exposure. Using iron staining and immunohistochemistry, concentrations of this metal and expression of several iron transport and storage proteins were evaluated at one day and one month following asbestos exposure. Iron was not stainable one day following asbestos instillation but was increased one month later. There was an elevated expression of duodenal cytochrome b (Dcytb), divalent metal transporter 1 (DMT1), and ferritin at both one day and one month after crocidolite exposure. While ferroportin (FPN1) expression was increased one day after asbestos exposure, levels of this metal exporter had returned to baseline at one month. TiO2 did not affect changes in either the iron concentration or the expression of these iron-related proteins at one day and one month. We conclude that asbestos exposure alters lung iron homeostasis with an accumulation of the metal resulting. Elevations in available iron affect changes in the expression of Dcytb, DMT1, ferritin, and FPN1, which further modify metal homeostasis in the lung.

AN - 67214207; 19431299 AB - Long term protection and maintenance of ecological communities and populations must consider the effect of atmospheric pollutants in addition to stressors that occur on the ground. We describe a technique for identifying species ranges and ecosystems across the landscape where there could be potential effects from air toxics releases. We modified the ranking equations for hazardous air pollutants (HAPs) from the Chemical Scoring and Ranking Assessment Model (SCRAM) to come up with a weighted relative toxicity value. The model combines toxicity rankings from SCRAM, chemical ambient air concentration data from the Assessment System for Population Exposure Nationwide model, and species richness data from the Southeast Gap Analysis Project. The final output was a 30-m pixel grid of potential vulnerability to HAP exposures. We found that the model, in general, resulted in a circular pattern around major urban areas with vulnerability decreasing with distance from the urban center. Those areas having high acreage of federal, state, and locally protected lands were also highlighted by the models added weight for species richness. Since the final toxicity maps were in a raster format the data can be aggregated into any number of assessment units for use by multiple levels of decision makers including federal and state entities who want to compare relative toxicity exposures across a region and local groups who want to evaluate the vulnerability of lands under their management.

AN - 67204982; 19411561 AB - Inorganic arsenic (iAs) is an environmental toxicant and human carcinogen. The enzymatic methylation of iAs that is catalyzed by arsenic (+3 oxidation state)-methyltransferase (AS3MT) generates reactive methylated intermediates that contribute to the toxic and carcinogenic effects of iAs. We have shown that clonal human urothelial cells (UROtsa/F35) that express rat AS3MT and methylate iAs are more susceptible to acute toxicity of arsenite (iAs(III)) than parental UROtsa cells that do not express AS3MT and do not methylate iAs. The current work examines transcriptional changes associated with AS3MT expression and identifies specific categories of genes expressed in UROtsa and UROtsa/F35 cells in response to a 24-h exposure to 1 or 50 microM iAs(III). Here, the expression of 21,073 genes was assessed using Agilent Human 1A(V2) arrays. Venn analysis showed marked concentration-dependent differences between gene expression patterns in UROtsa and UROTsa/F35 cells exposed to iAs(III). Among 134 genes altered by exposure to subtoxic 1 microM iAs(III), only 14 were shared by both cell lines. Exposure to cytotoxic 50 microM iAs(III) uniquely altered 1389 genes in UROtsa/F35 and 649 genes in UROtsa cells; 5033 altered genes were associated with the chemical alone. In UROtsa, but not UROtsa/F35 cells exposure to 1 microM iAs(III) altered expression of genes associated with cell adhesion. In contrast, expression of genes involved in cell cycle regulation was significantly altered in UROtsa/F35 cells at this exposure level. At 50 microM iAs(III), pathways regulating cell cycle, cell death, transcription, and metabolism were affected in both cell lines. However, only Urotsa/F35 cells showed numerous G-protein and kinase pathway alterations as well as alterations in pathways involved in cell growth and differentiation. These data link the AS3MT-catalyzed methylation of iAs to specific genomic responses in human cells exposed to iAs(III). Further analysis of these responses will help to characterize the role of AS3MT-catalyzed methylation in modulation of iAs(III) toxicity.

AN - 67181133; 19404385 AB - Birth defects are a major public health concern as they are the leading cause of neonatal and infant mortality. Observational studies have linked environmental pollution to adverse birth outcomes, including congenital anomalies. This study examined potential associations between ambient air pollution and congenital heart defects and cleft lip or palate among births in Brisbane, Australia (1998-2004). Ambient air pollution levels were averaged over weeks 3-8 of pregnancy among 150,308 births. Using a case-control design, we used conditional logistic regression and matched cases to 5 controls. Analyses were conducted using all births, and then births where the mother resided within 6 and 12 kilometers of an ambient air quality monitor. When analyzing all births there was no indication that ambient air pollution in Brisbane was associated with a higher risk of cardiac defects. Among births where the mother resided within 6 kilometers of an ambient air quality monitor, a 5 ppb increase in O(3) was associated with an increased risk of pulmonary artery and valve defects (OR 2.96, 95% CI: 1.34, 7.52) while a 0.6 ppb increase in SO(2) was associated with an increased risk of aortic artery and valve defects (OR 10.76, 95% CI: 1.50, 179.8). For oral cleft defects among all births, the only adverse association was between SO(2) and cleft lip with or without cleft palate (OR 1.27, 95% CI: 1.01, 1.62). However, various significant inverse associations were also found between air pollutants and birth defects. This study found mixed results and it is difficult to conclude whether ambient air pollution in Brisbane has an adverse association with the birth defects examined. Studies using more detailed estimates of air pollution exposure are needed.

AN - 67124504; 18717615 AB - Approaches for cleaning up contaminated sediments range from dredging to in situ treatment. In this study, we discuss the effects of amending reference and contaminated sediments with coal fly ash to reduce the bioavailability and toxicity of a field sediment contaminated with polycyclic aromatic hydrocarbons (PAHs). Six fly ashes and a coconut charcoal were evaluated in 7-d whole sediment toxicity tests with a marine amphipod (Ampelisca abdita) and mysid (Americamysis bahia). Fly ashes with high carbon content and the coconut charcoal showed proficiency at reducing toxicity. Some of the fly ashes demonstrated toxicity in the reference treatments. It is suspected that some of this toxicity is related to the presence of ammonia associated with fly ashes as a result of postoxidation treatment to reduce nitrous oxide emissions. Relatively simple methods exist to remove ammonia from fly ash before use, and fly ashes with low ammonia content are available. Fly ashes were also shown to effectively reduce overlying water concentrations of several PAHs. No evidence was seen of the release of the metals cadmium, copper, nickel, or lead from the fly ashes. A preliminary 28-d polychaete bioaccumulation study with one of the high-carbon fly ashes and a reference sediment was also performed. Although preliminary, no evidence was seen of adverse effects to worm growth or lipid content or of accumulation of PAHs or mercury from exposure to the fly ash. These data show fly ashes with high carbon content could represent viable remedial materials for reducing the bioavailability of organic contaminants in sediments.

Part I. Functionalities and performance of basic selection methods. AN - 67114759; 19343590 AB - To develop quantitative structure-activity relationships (QSAR) models capable of predicting adverse effects for large chemical inventories and diverse structures, an interactive approach is presented that includes testing of strategically selected chemicals to expand the scope of a preliminary model to cover a target inventory. The goal of chemical selection in this context is to make the testing more effective in terms of adding maximal new structural information to the predictive model with minimal testing. The aim of this paper is to describe a set of algorithmic solutions and modelling techniques that can be used to efficiently select chemicals for testing to achieve a variety of goals. One purpose of chemical selection is to refine the model thus extending our knowledge about the modelled subject. Alternatively, the selection of chemicals for testing could be targeted at achieving a more adequate structural representation of a specific universe of untested chemicals to extend the model applicability domain on each subsequent step of model development. The chemical selection tools are collectively provided in a software package referred to as ChemPick. The system also allows the visualisation of chemical inventories and training sets in multidimensional (two and three dimensions) descriptor space. The software environment allows one or more datasets to be simultaneously loaded in a three-dimensional (or N-dimensional) chart where each point represents a combination of values for the descriptors for a given conformation of a chemical. The application of the chemical selection tools to select chemicals to expand a preliminary model of human oestrogen receptor (hER) ligand binding to more adequately cover a diverse chemical inventory is presented to demonstrate the application of these tools.

AN - 66982866; 19253036 AB - The haloacetonitriles (HANs) exist in drinking water exclusively as byproducts of disinfection. HANs are found in drinking water more often, and in higher concentrations, when surface water is treated by chloramination. Human exposure occurs through consumption of finished drinking water; oral and dermal contact also occurs, and results from showering, swimming and other activities. HANs are reactive and are toxic to gastrointestinal tissues following oral administration. Such toxicity is characterized by GSH depletion, increased lipid peroxidation, and covalent binding of HAN-associated radioactivity to gut tissues. The presence of GSH in cells is an important protective mechanism against HAN toxicity; depletion of cellular GSH results in increased toxicity. Some studies have demonstrated an apparently synergistic effect between ROS and HAN administration, that may help explain effects observed in GI tissues. ROS are produced in gut tissues, and in vitro evidence indicates that ROS may contribute to the degradation and formation of reactive intermediates from HANs. The rationale for ROS involvement may involve HAN-induced depletion of GSH and the role of GSH in scavenging ROS. In addition to effects on GI tissues, studies show that HAN-derived radiolabel is found covalently bound to proteins and DNA in several organs and tissues. The addition of antioxidants to biologic systems protects against HAN-induced DNA damage. The protection offered by antioxidants supports the role of oxidative stress and the potential for a threshold in han-induced toxicity. However, additional data are needed to substantiate evidence for such a threshold. HANs are readily absorbed from the GI tract and are extensively metabolized. Elimination occurs primarily in urine, as unconjugated one-carbon metabolites. Evidence supports the involvement of mixed function oxidases, the cytochrome P450 enzyme family and GST, in HAN metabolism. Metabolism represents either a detoxification or bioactivation process, depending on the particular HAN and the enzyme involved. HANs can inhibit CYP2E1-mediated metabolism, an effect which may be dependent on a covalent interaction with the enzyme. In addition, HAN compounds inhibit GST-mediated conjugation, but this effect is reversible upon dialysis, indicating that the interaction does not represent covalent binding. No subchronic studies of HAN toxicity are available in the literature. However, studies show that HANs produce developmental toxicity in experimental animals. The nature of developmental toxicity is affected by the type of administration vehicle, which renders interpretation of results more difficult. Skin tumors have been found following dermal application of HANs, but oral studies for carcinogenicity are negative. Pulmonary adenomas were increased following oral administration of HANs, but the A/J strain of mice employed has a characteristically high background rate of such tumors. HANs interact with DNA to produce unscheduled DNA repair, SCE and reverse mutations in Salmonella. HANs did not induce micronuclei or cause alterations in sperm head morphology in mice, but did induce micronuclei in newts. Thus, there is concern for the potential carcinogenicity of HANs. It would be valuable to delineate any relationship between the apparent threshold for micronuclei formation in newts and the potential mechanism of toxicity involving HAN-induced oxidative stress. Dose-response studies in rodents may provide useful information on toxicity mechanisms and dose selection for longer term toxicity studies. Additional studies are warranted before drawing firm conclusions on the hazards of HAN exposure. Moreover, additional studies on HAN-DNA and HAN-protein interaction mechanisms, are needed. Such studies can better characterize the role of metabolism in toxicity of individual HANs, and delineate the role of oxidative stress, both of which enhance the capacity to predict risk. Most needed, now, are new subchronic (and chronic) toxicity studies; the results of such well-planned, controlled, conducted, interpreted and published investigations would be valuable in establishing margins of safety for HANs in human health risk assessment.

AN - 66951103; 19147833 AB - Although risk assessments are typically conducted on a chemical-by-chemical basis, the 1996 Food Quality Protection Act (FQPA) required the Environmental Protection Agency (EPA) to consider cumulative risk of chemicals that act via a common mechanism of toxicity. To this end, we are conducting studies with mixtures to provide a framework for assessing the cumulative effects of "antiandrogenic" chemicals. Rats were dosed during pregnancy with antiandrogens singly or in pairs at dosage levels equivalent to about one half of the ED50 for hypospadias or epididymal agenesis. The pairs include: AR antagonists (vinclozolin plus procymidone), phthalate esters (DBP plus BBP and DEHP plus DBP), a phthalate ester plus an AR antagonist (DBP plus procymidone), and linuron plus BBP. We predicted that each chemical by itself would induce few malformations; however, by mixing any two chemicals together, about 50% of the males would be malformed. All binary combinations produced cumulative, dose-additive effects on the androgen-dependent tissues. We also conducted a mixture study combining seven "antiandrogens" together. These chemicals elicit antiandrogenic effects at two different sites in the androgen signaling pathway (i.e., AR antagonist or inhibition of androgen synthesis). In this study, the complex mixture behaved in a dose-additive manner. Our results indicate that compounds that act by disparate mechanisms of toxicity display cumulative, dose-additive effects when present in combination.

AN - 66849400; 19161654 AB - 1,4-Dioxane has been identified as a probable human carcinogen and an emerging contaminant in drinking water. The United States Environmental Protection Agency's (U.S. EPA) National Exposure Research Laboratory (NERL) has developed a method for the analysis of 1,4-dioxane in drinking water at ng/L concentrations. The method consists of an activated carbon solid-phase extraction of 500-mL or 100-mL water samples using dichloromethane as the elution solvent. The extracts are analyzed by gas chromatography-mass spectrometry (GC-MS) in selected ion monitoring (SIM) mode. In the NERL laboratory, recovery of 1,4-dioxane ranged from 94-110% in fortified laboratory reagent water and recoveries of 96-102% were demonstrated for fortified drinking water samples. The relative standard deviations for replicate analyses were less than 6% at concentrations exceeding the minimum reporting level.

AN - 66843960; 19165386 AB - The current, continuous National Health and Nutrition Examination Survey (NHANES) has included blood mercury (BHg) and fish/shellfish consumption since it began in 1999. NHANES 1999-2004 data form the basis for these analyses. This study was designed to determine BHg distributions within U.S. Census regions and within coastal and noncoastal areas among women of childbearing age, their association with patterns of fish consumption, and changes from 1999 through 2004. We performed univariate and bivariate analyses to determine the distribution of BHg and fish consumption in the population and to investigate differences by geography, race/ethnicity, and income. We used multivariate analysis (regression) to determine the strongest predictors of BHg among geography, demographic factors, and fish consumption. Elevated BHg occurred more commonly among women of childbearing age living in coastal areas of the United States (approximately one in six women). Regionally, exposures differ across the United States: Northeast > South and West > Midwest. Asian women and women with higher income ate more fish and had higher BHg. Time-trend analyses identified reduced BHg and reduced intake of Hg in the upper percentiles without an overall reduction of fish consumption. BHg is associated with income, ethnicity, residence (census region and coastal proximity). From 1999 through 2004, BHg decreased without a concomitant decrease in fish consumption.

AN - 66842812; 19165382 AB - We conducted a review of the history and performance of developmental neurotoxicity (DNT) testing in support of the finalization and implementation of Organisation of Economic Co-operation and Development (OECD) DNT test guideline 426 (TG 426). In this review we summarize extensive scientific efforts that form the foundation for this testing paradigm, including basic neurotoxicology research, interlaboratory collaborative studies, expert workshops, and validation studies, and we address the relevance, applicability, and use of the DNT study in risk assessment. The OECD DNT guideline represents the best available science for assessing the potential for DNT in human health risk assessment, and data generated with this protocol are relevant and reliable for the assessment of these end points. The test methods used have been subjected to an extensive history of international validation, peer review, and evaluation, which is contained in the public record. The reproducibility, reliability, and sensitivity of these methods have been demonstrated, using a wide variety of test substances, in accordance with OECD guidance on the validation and international acceptance of new or updated test methods for hazard characterization. Multiple independent, expert scientific peer reviews affirm these conclusions.

AN - 66815651; 18808395 AB - It is well known that, under appropriate regularity conditions, the asymptotic distribution for the likelihood ratio statistic is chi(2). This result is used in EPA's benchmark dose software to obtain a lower confidence bound (BMDL) for the benchmark dose (BMD) by the profile likelihood method. Recently, based on work by Self and Liang, it has been demonstrated that the asymptotic distribution of the likelihood ratio remains the same if some of the regularity conditions are violated, that is, when true values of some nuisance parameters are on the boundary. That is often the situation for BMD analysis of cancer bioassay data. In this article, we study by simulation the coverage of one- and two-sided confidence intervals for BMD when some of the model parameters have true values on the boundary of a parameter space. Fortunately, because two-sided confidence intervals (size 1-2alpha) have coverage close to the nominal level when there are 50 animals in each group, the coverage of nominal 1-alpha one-sided intervals is bounded between roughly 1-2alpha and 1. In many of the simulation scenarios with a nominal one-sided confidence level of 95%, that is, alpha= 0.05, coverage of the BMDL was close to 1, but for some scenarios coverage was close to 90%, both for a group size of 50 animals and asymptotically (group size 100,000). Another important observation is that when the true parameter is below the boundary, as with the shape parameter of a log-logistic model, the coverage of BMDL in a constrained model (a case of model misspecification not uncommon in BMDS analyses) may be very small and even approach 0 asymptotically. We also discuss that whenever profile likelihood is used for one-sided tests, the Self and Liang methodology is needed to derive the correct asymptotic distribution.

AN - 66770048; 19110939 AB - Environmental regulators charged with protecting water quality must have scientifically defensible water quality goals. For protection of aquatic life, regulators need to know what levels of contaminants a water body can tolerate, without producing adverse effects. The USEPA has developed water quality criteria for many chemicals, but few are for current-use pesticides. Other countries also derive aquatic life criteria utilizing a variety of methodologies. As a prelude to developing a new criteria derivation methodology, this chapter explores the current state of aquatic life criteria derivation around the world. Rather than discussing each methodology independently, this review is organized according to critical elements that must be part of a scientifically defensible methodology. All of the reviewed methodologies rely on effects data to derive aquatic life criteria. Water quality criteria may be derived from single-species toxicity data by statistical extrapolation procedures (for adequate data sets), or by use of empirically based AFs (for data sets of any size). Assessment factor methods are conservative and have a low probability of underestimating risk, with a concomitant high probability of overestimating risk. Extrapolation methods may also under-, or overestimate risk, but uncertainty is quantifiable and is reduced when larger data sets are used. Although less common, methods are also available for criteria derivation using multispecies toxicity data. Environmental toxicity of chemicals is affected by several factors. Some of these factors can be addressed in criteria derivation, and some cannot. For example, factors such as magnitude, duration and frequency of exposure may be incorporated into criteria, either through use of time-to-event and population models or by derivation of both acute and chronic criteria that have duration and frequency components. Aquatic species may be exposed to hydrophobic organic chemicals by multiple routes. They may take up residues directly from water, or may be exposed dietarily, or combinations of both. Unfortunately, to properly address such multiple routes in criteria derivation, food web models are needed that work for chemicals that have specific modes of action. Similarly, both bioavailability and toxicity parameters may contribute to derivation of criteria, providing sufficient data are available. Ecotoxicological effects and physical-chemical data are needed for criteria derivation. The quality and quantity of required data are clearly stated in existing methodologies; some guidelines provide very specific data quality requirements. The level of detail provided by guidelines varies among methodologies. Most helpful are those that provide lists of acceptable data sources, descriptions of adequate data searches, schemes for rating ecotoxicity data, specifications of required data types (e.g., acute vs chronic), and instructions for data reduction. Many methodologies present procedures for deriving criteria from both large and small data sets. Very small data sets may be supplemented through the use of QSARs for selected pesticides, and through the use of models such as ICE (for prediction of toxicity to under-tested species), and ACE (for estimation of chronic toxicity from acute data). The toxicity of mixtures is addressed by several existing methodologies. In some cases, additional AFs are applied to criteria to account for exposure to mixtures, whereas in others, concentration addition models are used to assess compliance. Multiple stressors and bioaccumulation are also addressed in some methodologies, by providing for application of additional safety factors. Methods are also available for translating dietary exposure limits for humans or other fish-eating animals into water concentrations. Options for addressing the safety of TES exist, and rely heavily on data from surrogate species to derive criteria. Utilizing partition coefficients, criteria may be harmonized across media to ensure that levels set to protect one compartment do not result in unacceptable levels in other compartments. Several methodologies derive criteria from entire data sets through the use of statistical extrapolations; other methods utilize only the lowest (most sensitive) data point or points. Utilization of entire data sets allows derivation of confidence limits for criteria, and encourages data generation. Criteria derivation methodologies have improved over the past two decades as they have incorporated more ecological risk assessment techniques. No single existing methodology is ideal, but elements of several may be combined, and when used with newer risk assessment tools, will produce more usable and flexible criteria derivation procedures that are protective.

AN - 66754205; 18948380 AB - Species differences in the intrinsic clearance (CL(int)) and the enzymes involved in the metabolism of pyrethroid pesticides were examined in rat and human hepatic microsomes. The pyrethroids bifenthrin, S-bioallethrin, bioresmethrin, beta-cyfluthrin, cypermethrin, cis-permethrin, and trans-permethrin were incubated in rat and human hepatic microsomes in the presence or absence of NADPH. Metabolism was measured using a parent depletion approach. The CL(int) of the pyrethroids was 5- to 15-fold greater in rat relative to human microsomes except for trans-permethrin, which was approximately 45% greater in human microsomes. The metabolism of bifenthrin, S-bioallethrin, and cis-permethrin in rat and human hepatic microsomes was solely the result of oxidative processes. The metabolism of bioresmethrin and cypermethrin in human hepatic microsomes was solely the result of hydrolytic processes. Bioresmethrin and cypermethrin in rat hepatic microsomes and beta-cyfluthrin and trans-permethrin in microsomes from both species were metabolized by both oxidative and hydrolytic pathways. The metabolism of trans-permethrin was reduced when incubated with its diastereomer, cis-permethrin, in both rat and human hepatic microsomes. Rat cytochrome P450 (P450) isoforms that showed activity toward several pyrethroids included CYP1A1, CYP1A2, CYP2C6, CYP2C11, CYP3A1, and CYP3A2. Human P450 isoforms that showed activity toward multiple pyrethroids were CYP2C8, CYP2C9, CYP2C19, and CYP3A4. Species-specific differences in metabolism may result in variable detoxification of pyrethroids, which may in turn result in divergent neurotoxic outcomes. These species differences and isomer interactions in metabolism of pyrethroids should be considered when assessing the potential adverse health effects of pyrethroid pesticides.

AN - 66749331; 18560447 AB - The U.S. Environmental Protection Agency (EPA) and the U.S. Centers for Disease Control (CDC) co-organized a symposium on "Air Pollution Exposure and Health" at Research Triangle Park, North Carolina on September 19-20, 2006. The symposium brought together health and environmental scientists to discuss the state of the science and the cross-jurisdictional and methodological challenges in conducting air pollution epidemiology, environmental public health tracking and accountability research. The symposium was held over 2 days and consisted of technical presentations and breakout group discussions on each of the three principal themes of this meeting: (1) monitoring and exposure modeling information, (2) health effects data and (3) linkage of air quality and health data for research, tracking and accountability. This paper summarizes the symposium presentations and the conclusions and recommendations developed during the meeting. The accompanying two papers, which appear in this issue of the Journal, provide more in-depth discussion of issues pertinent to obtaining and analyzing air pollution exposure and health information. The symposium succeeded in identifying areas where there are critical gaps of knowledge in existing air pollution exposure and health information and in discovering institutional or programmatic barriers, which impede accessing and linking disparate data sets. Several suggestions and recommendations emerged from this meeting, directed toward (1) improving the utility of air monitoring data for exposure quantification, (2) improving access to and the quality of health data, (3) studying emerging air quality and health issues, (4) exploring improved or novel methods for linking data and (5) developing partnerships, building capacity and facilitating interdisciplinary communication. The meeting was successful in promoting an interdisciplinary dialogue around these issues and in formulating strategies to support these recommended activities. Finally, this symposium subsequently led to strengthening and initiating new partnerships or interactions between the EPA, CDC, States, academia and the research community at large.

AN - 66747909; 18418644 AB - American kestrels (Falco sparverius) were fed meat diets containing 0, 3, 6, or 12 ppm (dry weight) methylmercury chloride. Birds fed the 12-ppm diet started to show signs of neurotoxicity after 26 days and all died in 39-49 days. One male kestrel fed the 6-ppm diet died after 75 days of exposure and several others showed signs of neurotoxicity after 45 days. None of the birds fed the 3-ppm diet died or showed signs of toxicity. After 59 days of exposure, mercury concentrations in the liver, kidney, and blood of nonreproducing kestrels increased with increasing dietary concentration. Tissue concentrations of mercury also steadily increased over time in birds fed diets with 6 ppm mercury, which were necropsied at 8, 15, 29, or 59 days of exposure, reaching mean total mercury concentrations of 57, 46, and 45 ppm (wet weight) at 59 days in the liver, kidney, and whole blood, respectively. Two pairs of kestrels at each dietary concentration were allowed to breed. Eggs averaged 8.3 and 18.1 ppm (wet weight) total mercury from birds fed 3- and 6-ppm diets, respectively. Feathers grown during mercury exposure contained high concentrations of mercury: Birds fed 3- and 6-ppm diets contained 275 and 542 ppm total mercury, respectively.

AN - 66738994; 19066483 AB - Since 11 September 2001, improvised nuclear devices have become recognized as an important radiological threat requiring emergency response planning. Although Protective Action Guidance is well established for fixed nuclear facilities, correspondingly well-developed guidance does not exist for nuclear explosions. The Washington State Department of Health has developed preplanned Protective Action Recommendations for improvised nuclear device explosions. These recommendations recognize the need for advice to the public soon after such an event, before significant data are available. They can be used before significant outside support is available locally, and reference observable effects so people can use them if communications were disabled. The recommendations focus on early actions (24-48 h) and place priority on actions to avoid deterministic health effects due to residual fallout. Specific emphasis is placed on determining recommendations for evacuation, as well as the extent of the area for sheltering. The key recommendations developed for an initial public response are: (1) if there is ready access to robust shelter such as an underground basement or interior spaces in a multi-story structure, immediate sheltering in these areas is the best action, regardless of location; (2) if robust shelter is not available, and if fallout is observed in the area, then evacuation is the best general recommendation for locations within 16 km (10 miles) of the explosion; and (3) beyond 16 km (10 miles), the generally recommended protective action is to shelter in the best-protected location which is readily available.

AN - 66736448; 18978342 AB - Previous studies demonstrated that perinatal exposure to polybrominated diphenyl ethers (PBDEs), a major class of brominated flame retardants, may affect thyroid hormone (TH) concentrations by inducing hepatic uridinediphosphate-glucoronosyltransferases (UGTs). This study further examines effects of the commercial penta mixture, DE-71, on genes related to TH metabolism at different developmental time points in male rats. DE-71 is predominately composed of PBDE congeners 47, 99, 100, 153, 154 with low levels of brominated dioxin and dibenzofuran contaminants. Pregnant Long-Evans rats were orally administered 1.7 (low), 10.2 (mid), or 30.6 (high) mg/kg/day of DE-71 in corn oil from gestational day (GD) 6 to postnatal day (PND) 21. Serum and liver were collected from male pups at PND 4, 21, and 60. Total serum thyroxine (T(4)) decreased to 57% (mid) and 51% (high) on PND 4, and 46% (mid) dose and 25% (high) on PND 21. Cyp1a1, Cyp2b1/2, and Cyp3a1 enzyme and mRNA expression, regulated by aryl hydrocarbon receptor, constitutive androstane receptor, and pregnane xenobiotic receptor, respectively, increased in a dose-dependent manner. UGT-T(4) enzymatic activity significantly increased, whereas age and dose-dependent effects were observed for Ugt1a6, 1a7, and 2b mRNA. Sult1b1 mRNA expression increased, whereas that of transthyretin (Ttr) decreased as did both the deiodinase I (D1) enzyme activity and mRNA expression. Hepatic efflux transporters Mdr1 (multidrug resistance), Mrp2 (multidrug resistance-associated protein), and Mrp3 and influx transporter Oatp1a4 mRNA expression increased. In this study the most sensitive responses to PBDEs following DE-71 exposure were CYP2B and D1 activities and Cyb2b1/2, d1, Mdr1, Mrp2, and Mrp3 gene expression. All responses were reversible by PND 60. In conclusion, deiodination, active transport, and sulfation, in addition to glucuronidation, may be involved in disruption of TH homeostasis due to perinatal exposure to DE-71 in male rat offspring.

AN - 66736351; 18973770 AB - Mechanisms of particulate matter (PM)-induced cardiotoxicity are not fully understood. Direct translocation of PM-associated metals, including zinc, may mediate this effect. We hypothesized that following a single intratracheal instillation (IT), zinc directly translocates outside of the lungs, reaching the heart. To test this, we used high resolution magnetic sector field inductively coupled plasma mass spectrometry to measure levels of five stable isotopes of zinc ((64)Zn, (66)Zn, (67)Zn, (68)Zn, (70)Zn), and copper in lungs, plasma, heart, liver, spleen, and kidney of male Wistar Kyoto rats (13 weeks old, 250-300 g), 1, 4, 24, and 48 h following a single IT or oral gavage of saline or 0.7 micromol/rat (70)Zn, using a solution enriched with 76.6% (70)Zn. Natural abundance of (70)Zn is 0.62%, making it an easily detectable tracer following exposure. In IT rats, lung (70)Zn was highest 1 h post IT and declined by 48 h. Liver endogenous zinc was increased 24 and 48 h post IT. (70)Zn was detected in all extrapulmonary organs, with levels higher following IT than following gavage. Heart (70)Zn was highest 48 h post IT. Liver, spleen and kidney (70)Zn peaked 4 h following gavage, and 24 h following IT. (70)Zn IT exposure elicited changes in copper homeostasis in all tissues. IT instilled (70)Zn translocates from lungs into systemic circulation. Route of exposure affects (70)Zn translocation kinetics. Our data suggests that following pulmonary exposure, zinc accumulation and subsequent changes in normal metal homeostasis in the heart and other organs could induce cardiovascular injury.

AN - 66721175; 18979354 AB - Dibutyltin (DBT), a widely used plastic stabilizer, has been detected in the environment as well as human tissues. Although teratological and developmental effects are well documented, there are no published reports of DBT effects on the developing nervous system. As part of a developmental neurotoxicity study of DBT, tissue samples were periodically collected to determine the distribution of total tin (Sn) in brain and whole blood. Pregnant Sprague-Dawley rats were exposed to 0, 10, or 25 ppm DBT in drinking water from gestational day (GD) 6 to weaning at postnatal day (PND) 21. Beginning on PND 3, half of the litters were directly dosed every 2 to 3 d via oral gavage with 0, 1, or 2.5 mg/kg DBT such that the dose level matched the water concentration (for example, litters with 25 ppm DBT in the water received 2.5 mg/kg). For Sn analysis, brain and blood samples were collected from culled pups on PND2 (males and females pooled), from pups (males and females separately) as well as dams at weaning (PND21), and from adult offspring (males and females) at PND93. Total Sn was quantified using inductively coupled plasma-mass spectroscopy (ICP-MS). At all ages, brain Sn levels were higher than blood. At culling, in the directly dosed pups at weaning, and in dams at weaning, Sn levels in both tissues were linearly related to dose. Weanling pups without direct dosing showed lower levels than either culled pups or dams, indicating that lactational exposure was minimal or negligible even while maternal exposure is ongoing. In the adults, Sn levels persisted in brains of directly dosed rats, and the high-dose females had higher levels than did high-dose males. No Sn was detected in adult blood. Thus, during maternal exposure to DBT in drinking water, Sn is placentally transferred to the offspring, but lactational transfer is minimal, if any. Furthermore, Sn is concentrated in brain compared to blood, and its elimination is protracted, on the order of days to months after exposure ends. JF - Journal of toxicology and environmental health.

Halfway Creek Marsh, at the junction of Halfway Creek and the Mississippi River on Wisconsin's western border, is representative of such historical transformation. This marsh became the focus of a 2005-2006 investigation by scientists from the U.S. Geological Survey, the University of Wisconsin-Madison, and the U.S. Environmental Protection Agency, who used an understanding of the historical transformation to help managers identify possible restoration alternatives for Halfway Creek Marsh. Field-scale topographic surveys and sediment cores provided data for reconstructing patterns and rates of historical overbank sedimentation in the marsh. Information culled from historical maps, aerial photographs, General Land Office Survey notes, and other historical documents helped establish the timing of anthropogenic disturbances and document changes in channel patterns. Major human disturbances, in addition to agricultural land uses, included railroad and road building, construction of artificial levees, drainage alterations, and repeated dam failures associated with large floods. A volume of approximately 1,400,000 m (super 3) , involving up to 2 m of sandy historical overbank deposition, is stored through the upper and lower marshes and along the adjacent margins of Halfway Creek and its principal tributary, Sand Lake Coulee. The estimated overbank sedimentation rate for the entire marsh is approximately 3,000 m (super 3) yr (super -1) for the recent period 1994-2006. In spite of reduced surface runoff and soil erosion in recent years, this recent sedimentation rate still exceeds by approximately 4 times the early settlement (1846-1885) rate of 700 m (super 3) yr (super -1) , when anthropogenic acceleration of upland surface runoff and soil erosion was beginning. The highest rate of historical bottomland sedimentation occurred from 1919 to 1936, when the estimated overbank sedimentation rate was 20,400 m (super 3) yr (super -1) . This rate exceeded by nearly 30 times the 1846-1886 rate. Artificial levees were constructed along the upper reach of Halfway Creek in the marsh during the early twentieth century to restrict flooding on the adjacent bottomlands. Anomalously high overbank sedimentation rates subsequently occurred on the floodplain between the levees, which also facilitated more efficient transport of sediment into the lower marsh bottomland. Although overbank sedimentation rates dropped after 1936, corresponding to the widespread adoption of soil-conservation and agricultural best-management practices, the continuation of anomalously high overbank sedimentation between the levees led to increased bank heights and development of a relatively deep channel. The deep cross-section morphology is commonly mistaken as evidence of channel incision; however, this morphology actually resulted from excessive overbank sedimentation. The historical metamorphosis of the Halfway Creek channel and riparian wetlands underscores the importance of understanding the long-term history of channel and floodplain evolution when restoration of channels and riparian wetlands are under consideration. Sedimentation patterns and channel morphology for Halfway Creek Marsh probably are representative of other anthropogenically altered riparian wetlands in the Upper Mississippi River System and similar landscapes elsewhere.

Substantial differences in imagery, legends, and methods between these two land cover products must be overcome in order to support direct comparison. The NLCD 1992-2001 Land Cover Change Retrofit product was developed to provide more accurate and useful land cover change data than would be possible by direct comparison of NLCD 1992 and NLCD 2001. For the change analysis method to be both national in scale and timely, implementation required production across many Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) path/rows simultaneously. To meet these requirements, a hybrid change analysis process was developed to incorporate both post-classification comparison and specialized ratio differencing change analysis techniques. At a resolution of 30 meters, the completed NLCD 1992-2001 Land Cover Change Retrofit product contains unchanged pixels from the NLCD 2001 land cover dataset that have been cross-walked to a modified Anderson Level I class code, and changed pixels labeled with a "from-to" class code. Analysis of the results for the conterminous United States indicated that about 3 percent of the land cover dataset changed between 1992 and 2001. JF - Open-File Report - U. S.

While it is a small group of water systems, they serve nearly 10% of the publicly supplied population in the United States. Their regulatory performance as a group is not as good as other directly supplied water systems. However, if they purchase their GUDI water, they may have a somewhat better regulatory performance. GUDI is defined as any water beneath the surface of the ground with significant occurrence of insects, other macroorganisms, algae, or large diameter pathogens such as Giardia lamblia or any water beneath the surface of the ground with significant and relatively rapid shifts in water characteristics such as turbidity, temperature, conductivity, or pH that closely correlates with climatological or surface water conditions (40 CFR 141.2). The determination of GUDI is based on criteria set by states and measured through water quality analysis or documentation from well construction or field geological evaluation. These waters may result from ground water-surface water interaction that has received significant attention in the literature, but has characteristics more like surface waters that affect their quality. Thus, they are regulated under the Safe Drinking Water Act as surface waters.

This includes sites subject to petroleum releases, exposure to landfill leachates, and OC additions for biostimulation of reductive dechlorination of chlorinated solvents. The key characteristic of these sites is that, under conditions prevailing before the anthropogenic OC introduction, the naturally occurring As in the subsurface was not mobile and did not adversely affect ground water quality. This suggests that, in the far-field (where background conditions are (re) established), As may be sequestered upon contact of the contaminated ground water with either or both the (uncontaminated) ambient ground water and the background aquifer minerals. The observed extents of elevated concentrations (or "footprints") of As and other chemical species, such as dissolved OC and iron (Fe), and related parameters, such as redox potential (E (sub h) ) and dissolved oxygen, and their evolution over time can be used to assess the mobilization and sequestration of As and the potential feasibility of MNA as a remedial option. Ultimately, the capacity for As sequestration must be assessed in the context of the OC loading to the site, which may require "active" measures for source control. Monitoring is needed to confirm the continuing effectiveness of the MNA remedy or to indicate if contingency measures must be implemented.

These samples were analyzed for nitrate stable isotopes, nutrients, major ions, and age-dating constituents to determine if nitrate-stable isotopes can be used to differentiate food-processing waste from other potential sources of nitrate. Major-ion data from each site were used to determine which samples were associated with the recharge of the food-processing wastewater. End-member mixing analysis was used to determine the relative amounts of each identified end member within the samples collected from the Terrace Farm site. The delta nitrogen-15 (delta (super 15) N) of nitrate generally ranged between +2 and +9 parts per thousand and the delta oxygen-18 (delta (super 18) O) of nitrate generally ranged between -2 and -7 parts per thousand. None of the samples that were determined to be associated with the wastewater were different from the samples that were not affected by the wastewater. The nitrate isotope values measured in this study are also characteristic of ammonium fertilizer, animal and human waste, and soil nitrate; therefore, it was not possible to differentiate between food-processing wastewater and the other nitrate sources. Values of delta (super 15) N and delta (super 18) O of nitrate provided no more information about the sources of nitrate in the Umatilla River basin than did a hydrologic and geochemical understanding of the ground-water system derived from interpreting water-level and major-ion chemistry data.

The agency is responsible for providing information and technical assistance to the more than 50,000 water utilities across the country. The distributed physical layout of drinking-water utilities makes them inherently vulnerable to contamination incidents caused by terrorists. To counter this threat, the EPA is using operations research to design, test, and deploy contamination warning systems (CWSs) that rapidly detect the presence of contaminants in drinking water. We developed a software tool to optimize the design process, published a decision-making process to assist utilities in applying the tool, pilot-tested the tool on nine large water utilities, and provided training and technical assisstance to a larger group of utilities. We formed a collaborative team of industry, academia, and government to critique our approach and share CWS deployment experiences. Our work has demonstrated that a CWS is a cost-effective, timely, and capable method of detecting a broad range of contaminants. Widespread application of these new systems will significantly reduce the risks associated with catastrophic contamination incidents: the median estimated fatalities reduction for the nine utilities already studied is 48 percent; the corresponding economic-impact reduction is over $19 billion. Because of this operations research program, online monitoring programs, such as a CWS, are now the accepted technology for reducing contamination risks in drinking water.

Cap-and-trade has been applied to various air pollutants including sulphur dioxide, nitrogen oxides and volatile organic compounds in the United States and carbon dioxide (CO2) in the European Union. This corresponds to what is likely to become the most expensive environmental undertaking in history - the effort to reduce the heating of the planet. However, the efficacy of a cap-and-trade policy for CO2 depends in large part on the design of the program. In addition to the level of the cap, the most important decision facing policymakers will be the initial allocation of emissions allowances. The method used to allocate tradable emissions allowances will have significant influence on the distributional impact and efficiency of the program.

Public utility service providers have often been seen as lacking the capacity to identify and/ or implement the needed transformation processes. Instead, privatization has been proposed as a panacea to remedy this deficit. However, privatization projects are often not realized because they encounter strong political opposition. This article presents the results of strategic planning projects in three public wastewater organizations in Switzerland. This study suggests that if appropriate processes are implemented, public utility organizations are able to overcome their limitations in identifying the relevant capability deficits and select adequate strategies to compensate for the deficits. While these strategies may deviate substantially across utilities due to differences in the goals pursued, the widespread adoption of strategic planning methods by public utilities represents a viable alternative to privatization.

The useable database from this literature comprised studies reporting effects of long-term exposure to PERC, effects that included slowed reaction times, cognitive deficits, impaired color vision, and reduced visual contrast sensitivity. For the meta-analyses, dose was defined as the product of the concentration inhaled PERC and the duration of exposure, expressed in unites of ppm-h/1000 (for numerical convenience). Dose-related results were highly variable across studies. Reports involving low exposure concentrations characteristic of nonoccupational exposures consistently produced effects of a magnitude that were comparable to those reported for higher concentration occupational studies. If this finding is reliable and general, studies of occupationally exposed persons may underestimate the magnitude of effects of PERC and other chemicals in the total population. Given the limited scope of the available data for PERC and its methodological and reporting problems (small sample sizes, testers were not blind to the subjects' exposure conditions, and the timing and location of testing were insufficiently documented), it seems important to test this conclusion with a well-documented study of two groups (occupational and nonoccupational exposure) in which subjects are evaluated in randomized order, using the same procedures and with the testers kept blind to the status of the subjects.

Depending on the characteristics of the source water and treatment processes used, both types and concentrations of DBPs found in drinking waters vary substantially. The composition of a drinking-water mixture also may change during distribution. This study evaluated the relationships between mutagenicity, using the Ames assay, and water quality parameters. The study included information on treatment, mutagenicity data, and water quality data for source waters, finished waters, and distribution samples collected from five full-scale drinking water treatment plants, which used chlorine exclusively for disinfection. Four of the plants used surface water sources and the fifth plant used groundwater. Correlations between mutagenicity and water quality parameters are presented. The highest correlation was observed between mutagenicity and the total organic halide concentrations in the treated samples.

It is estimated that infants eat twice as much dust (100 mg vs. 50 mg/d), weigh one sixth as much, and are up to ten times more vulnerable than are adults to dust exposure (U.S. EPA 2002, 2003). The developing neurological, immune, digestive, and other bodily systems of infants are easily affected at low doses and these systems are less able to metabolize, detoxify, and excrete pollutants (Grandjean and Landrigan 2006; U.S. EPA 1996, 2002, 2003). Up to 11% of toddlers may exhibit pica behavior, eating nonfood items, and may consume up to 10 g of soil and dust per day (Calabrese and Stanek 1991; Mahaffey and Annest 1985). The time of life when exposure occurs may be as important as the dose (Grandjean and Landrigan 2006; Louis et al. 2007). Infants breathe more air, drink and eat more relative to their body weight, and engage in risky behaviors such as mouthing hands, toys, furniture, and other nonfood items. They crawl on floors, where they are in close proximity to carpets, and may breathe higher levels of dust (Rodes et al. 1996). Exposures early in life may trigger sensitization leading to development of chronic diseases such as asthma or predispose to cancer that takes decades to develop (Louis et al. 2007).

Nonmetric multidimensional scaling (NMDS) ordination of electrofishing catch-per-effort data revealed an overriding geographic and anthropogenic stressor gradient that appeared to structure fish composition via impacts on water clarity and vegetation structure. Wetlands in Lakes Erie and Michigan with agricultural watersheds, turbid water, little submerged vegetation, and a preponderance of generalist, tolerant fishes occupied one end of this gradient, while wetlands in Lake Superior with largely natural watersheds, clear water, abundant submerged vegetation, and diverse fishes occupied the other. Fish composition was also related to wetland morphology, hydrology, exposure, and substrate, but this was only evident within low-disturbance wetlands. Anthropogenic stress appears to homogenize fish composition among wetlands and mask other fish-habitat associations. Because land use is strongly spatially patterned across the Great Lakes and aquatic vegetation is a key habitat element that responds to both biogeography and disturbance, it is difficult to disentangle natural from anthropogenic drivers of coastal wetland fish composition.Original Abstract: Nous analysons des donnees provenant de terres humides riveraines reparties sur l'ensemble des Grands Lacs laurentiens afin d'identifier les patrons d'associations de poissons et leurs relations avec les habitats, les conditions du bassin versant et l'environnement regional. Une ordination de cadrage non metrique multidimensionnel (NMDS) de donnees de captures par unite d'effort de peche electrique revele l'existence d'un gradient predominant de facteurs de stress geographiques et anthropiques qui semble structurer la composition des peuplements de poissons par son impact sur la clarte de l'eau et la structure de la vegetation. Les terres humides aux lacs Erie et Michigan avec des bassins versants agricoles, de l'eau turbide, une vegetation submergee rare et une preponderance de poissons generalistes et tolerants, occupent une extremite de ce gradient; en revanche, les terres humides du lac Superieur avec des bassins versants en grande partie naturels, de l'eau claire, une vegetation submergee abondante et une diversite de poissons, occupent l'autre extremite. La composition des peuplements de poissons est aussi en relation avec la morphologie des terres humides, l'hydrologie, l'exposition et le substrat, mais la relation n'est evidente que dans les terres humides peu perturbees. Le stress anthropique semble homogeneiser la composition des peuplements de poissons dans les differentes terres humides et masquer les autres associations poissons-habitats. Parce que l'utilisation des terres dans la region des Grands Lacs forme un patron spatial bien marque et que la vegetation est un element essentiel de l'habitat qui reagit a la fois a la biogeographie et aux perturbations, il est difficile de demeler les facteurs explicatifs naturels et anthropiques de la composition des peuplements de poissons dans les terres humides riveraines.

The framework addresses three issues complicating assessments of climate change impacts-linkages across spatial scales, linkages across temporal scales, and linkages across scientific and management disciplines. A major theme underlying the framework is that, due to current limitations in modeling capabilities, assessing and responding to climate change should be approached from the perspective of risk assessment and management rather than as a prediction problem. The framework is based generally on ecological risk assessment and similar approaches. A second theme underlying the framework is the need for close collaboration among climate scientists, scientists interested in assessing impacts, and resource managers and decision makers. A case study illustrating an application of the framework is also presented that provides a specific, practical example of how the framework was used to assess the impacts of climate change on water quality in a mid-Atlantic, U.S., watershed.

We evaluated species diversity among different land uses, including, commercial, forested, residential, and agriculture, and determined relationships among disturbance scale, habitat requirements, contaminants, and patterns in species distributions. Primary burrowing species, Cambarus polychromatus, Cambarus cf diogenes (Lacunicambarus A), and Fallicambarus fodiens, were tolerant of higher concentrations of contaminants than aquatic tertiary burrowing species. Cambarus polychromatus was among the last species of crayfish at the most disturbed sites, while it was absent from pasture and agricultural landscapes that allowed cattle access along banks. Four species of Orconectes were found in the reference and agricultural landscapes within the watershed, including O. immunis, O. indianensis, O. inermis inermis, and O. propinquus. Orconectes indianensis distribution was determined by the presence of rock habitat and absence of contaminants. No Orconectes species were found in acid mine leachate-affected streams with high levels of molybdenum. Cambarus laevis was found in the highest-quality reference areas, which were associated with karst habitats and no contaminants. Burrowing crayfish species were associated with the oil derricks in the lower and middle watershed, which contained increased concentrations of strontium, phosphorus, and various organic parameters associated with oil brine PAHs.

First, environmental burden reduction involves green process and engineering, emissions control, desulfurization/denitrification of nonrenewable energy sources, and improvement of agriculture and food systems. Second, reduction/treatment of industrial and agricultural wastes involves converting wastes into products, groundwater remediation, adsorption, delaying photocatalysis, and nanomembranes. Third, NPS pollution control involves controlling water pollution. Nanomaterials alter physical properties on a nanoscale due to their high specific surface area to volume ratio. They are used as catalysts, adsorbents, membranes, and additives to increase activity and capability due to their high specific surface areas and nano-sized effects. Thus, nanomaterials are more effective at treating environmental wastes because they reduce the amount of material needed.

Previous in vitro studies have reported NDP to be biologically inert with negligible cytotoxicity, implying that they are potentially suitable for novel drug delivery applications. Separate studies, however, have shown that elemental carbon particles, a material closely related to NDP, can induce inflammatory responses in the lung. To assess the potential toxicity of exposure to NDP, we examined its effects on IL-8 expression by human airway epithelial cells (HAEC) in vitro. Four-hour exposures of HAEC to 66 kg/ml NDP resulted in IL-8 mRNA increases up to 70-fold over control levels and were accompanied by up to 14-fold increases in IL-8 protein levels in the media. Adenoviral overexpression of catalase significantly reduced NDP-induced IL-8 mRNA expression in HAEC. Interestingly, exposure to NDP did not increase IL-8 transcriptional activity, as measured with the use of IL-8 promoter reporter constructs. Rather, NDP treatment was found to markedly increase the half-life of IL8-mRNA transcripts in HAEC. These findings show a pronounced increase in the expression of IL-8 in HAEC, suggesting that NDP inhalation can cause inflammatory responses in the human lung.

The study objective was to assess the utility of larval salamanders and habitat variables for determining stream permanence across a large geographic area. We sampled four core forests (61 sites in IN, KY, and OH) in spring (April-May) and summer (August-September) over a 2-year period. Sites in each forest were selected to cover a gradient of permanence, from perennial to ephemeral. Salamanders were collected by both benthic core sampling and timed visual search on each site visit. Classification and regression tree (CART) models were used to identify indicators of seasonal permanence at core sites that were then tested using data collected from 6 satellite forests (52 sites) located nationwide. Southern two-lined salamanders, Eurycea cirrigera, were numerically dominant and were the only species included in CART models. Salamander diversity declined with distance from the Appalachians and strong longitudinal changes in assemblage composition were evident within streams. Abundance of E. cirrigera was positively correlated with watershed area, whereas dusky salamanders, Desmognathus spp., and spring salamanders, Gyrinophilus porphyriticus, comprised a greater proportion of salamander communities at intermittent sites within their range. Spring and summer CART models incorporated E. cirrigera abundance and measures of channel geomorphology to accurately classify approximately 80% of core sites as either ephemeral, intermittent or perennial. When applied to validation data from national satellite forests, correct classification rates were >85% for intermittent and ephemeral sites, but were only ~20% for perennial sites. These findings suggest that larval plethodontid salamanders and habitat variables can be valuable predictors of headwater stream hydroperiod, but indicators are largely limited to the regional scale.

However, the underlying biogeochemical processes are not fully understood. The objective of this 4-yr study was to examine the effects of riparian zone restoration on soil N cycling mechanisms in a mountain pasture previously degraded by cattle. Soil inorganic N pools, fluxes, and transformation mechanisms were compared across the following experimental treatments: (i) a restored area with vegetation regrowth; (ii) a degraded riparian area with simulated effects of continued grazing by compaction, vegetation removal, and nutrient addition (+N); and (iii) a degraded riparian area with simulated compaction and vegetation removal only (- N). Soil solution NO sub(3) super(-) concentrations and fluxes of inorganic N in overland flow were >90% lower in the restored treatment relative to the degraded (+N) treatment. Soil solution NO sub(3) super(-) concentrations decreased more rapidly in the restored treatment relative to the degraded (-N) following cattle (Bos taurus) exclusion. Mineralization and nitrification rates in the restored treatment were similar to the degraded (-N) treatment and, on average, 75% lower than in the degraded (+N) treatment. Nitrogen trace gas fluxes indicated that restoration increased the relative importance of denitrification, relative to nitrification, as a pathway by which N is diverted from the receiving stream to the atmosphere. Changes in soil nutrient cycling mechanisms following restoration of the degraded riparian zone were primarily driven by cessation of N inputs. The recovery rate, however, was influenced by the rate of vegetation regrowth.

To assess environmental and/or human health risks from these nanoparticles, there is a need to identify the chemical transformations that silver nanoparticles undergo in different environments. Thus an antimicrobial sock material containing Ag nanoparticles was examined by X-ray absorption spectroscopy to identify the speciation of Ag. The material was exposed to a hypochlorite/detergent solution and subjected to agitation. An elemental Ag nanopowder was also exposed to the hypochlorite/detergent solution or to a 1 mol L super(-1) NaCl solution. Results showed that the sock material nanoparticles consisted of elemental Ag. After exposure to the hypochlorite/detergent solution, a significant portion (more than 50%) of the sock nanoparticles were converted, in situ, to AgCl. Results from exposures to elemental Ag nanopowder suggest that an oxidation step is necessary for the elemental Ag nanoparticles to transform into AgCl as there was no evidence of AgCl formation in the presence of chloride alone. As a result, if Ag ions leach from consumer products, any chloride present may quickly scavenge the ions. In addition, the efficacy of Ag, as an antimicrobial agent in fabrics, may be limited, or even negated, after washing in solutions containing oxidizers as AgCl is much less reactive than Ag ion.

When dose-response data are available for the actual environmental mixture to which individuals are exposed (i.e., the mixture of concern), these data provide the best information for dose-response assessment of the mixture. When suitable data on the mixture itself are not available, surrogate data might be used from a sufficiently similar mixture or a group of similar mixtures. Consequently, the determination of whether the mixture of concern is "sufficiently similar" to a tested mixture or a group of tested mixtures is central to the use of whole mixture methods. This article provides an overview for a series of companion articles whose purpose is to develop a set of biostatistical, chemical, and toxicological criteria and approaches for evaluating the similarity of drinking-water disinfection by-product (DBPs) complex mixtures. Together, the five articles in this series serve as a case study whose techniques will be relevant to assessing similarity for other classes of complex mixtures of environmental chemicals. Schenck et al. (2009) describe the chemistry and mutagenicity of a set of DBP mixtures concentrated from five different drinking-water treatment plants. Bull et al. (2009a, 2009b) describe how the variables that impact the formation of DBP affect the chemical composition and, subsequently, the expected toxicity of the mixture. Feder et al. (2009a, 2009b) evaluate the similarity of DBP mixture concentrates by applying two biostatistical approaches, principal components analysis, and a nonparametric "bootstrap" analysis. Important factors for determining sufficient similarity of DBP mixtures found in this research include disinfectant used; source water characteristics, including the concentrations of bromide and total organic carbon; concentrations and proportions of individual DBPs with known toxicity data on the same endpoint; magnitude of the unidentified fraction of total organic halides; similar toxicity outcomes for whole mixture testing (e.g., mutagenicity); and summary chemical measures such as total trihalomethanes, total haloacetic acids, total haloacetonitriles, and the levels of bromide incorporation in the DBP classes.

The presettled samples contained suspended solids (SS) and dissolved organic carbon (DOC) at concentrations of 28 and 290 mg/L, respectively. Disinfection with Fenton's Reagent was carried out at a pH between 5.90 and 6.0 and at a temperature of 25°C. All disinfected samples contained residual oxidants. Under all reaction conditions studied, complete inactivation of E. coli was achieved within one minute of the addition of Fenton's Reagent. Disinfection with hydrogen peroxide alone under similar conditions is incomplete even under much longer contact times.

All soil experiments were conducted at 1000 ppm and soil loads of 6-10 mg soil/cm super(2). After 96 h the percentage of applied dose absorbed (PADA) for TCB sorbed on LOS was 49.7 (rat, in vivo), 31.9 (rat, in vitro), and 7.4 (human, in vitro). The 96-h PADA for TCB sorbed on HOS was 9.6% (rat, in vitro). Generally, rat skin was observed to be four- to ninefold more permeable to TCB than human skin (in vitro). At steady state, the dermal flux of TCB on LOS at 1000 ppm and on HOS at 1000 ppm (both in vitro, rat) was 33 and 10 ng/cm super(2)/h, respectively (ratio = 3.3).

For traditional diesel fuel exhaust, it has been demonstrated that the particulate matter (PM) organic components play a role in acute inflammatory reactions. However, there have been only a few cytotoxicity and mutagenicity studies on biodiesel emissions. In this study, BEAS-2B cells, a transformed human airway epithelial cell line, were exposed in vitro to the PM organic extracts from Standard Reference Material (SRM) 1975, soy ethyl ester (SEE), soy methyl ester (SME), and petroleum diesel for 24 hours. This study demonstrated that the organic extracts of biodiesel PM in an aqueous solution can increase the release of pro-inflammatory cytokines IL-8 and IL-6 by respiratory epithelial cells. On a microgram PM equivalent per ml ([mu]g PM eq/ml) basis, exposure to biodiesel extracts was associated with a greater release of IL-8 and IL-6 relative to organic extracts of two diesel PM samples. The dose range tested was not cytotoxic. It was also noted that the solvent exchange method, which was used to prepare the aqueous exposure doses, may not be appropriate for the investigation of biodiesel extracts, though it has been used extensively in petroleum diesel research. A valuable new finding from these experiments is that the soluble organic fraction (SOF) of biodiesel PM begins to elicit a cytokine response in BEAS-2B cells at an exposure lower than petroleum diesel PM extract (approximately 40 [mu]g PM eq/ml). However, more research is required to better characterize the potency of the organic fraction of biodiesel compared to petroleum diesel.

By incorporating individual variability conferred by genetic polymorphisms, health conditions, and physiological changes during development and aging, PBPK models are ideal for predicting chemical disposition in various subpopulations of interest. In order to improve the parameterization of PBPK models for healthy and health-impaired elderly (herein defined as those aged 65 yr and older), physiological parameter values were obtained from the peer-reviewed literature, evaluated, and entered into a Microsoft ACCESS database. Database records include values for key age-specific model inputs such as ventilation rates, organ volumes and blood flows, glomerular filtration rates, and other clearance-related processes. In total, 528 publications were screened for relevant data, resulting in the inclusion of 155 publications comprising 1051 data records for healthy elderly adults and 115 data records for elderly with conditions such as diabetes, chronic obstructive pulmonary disease (COPD), obesity, heart disease, and renal disease. There are no consistent trends across parameters or their associated variance with age; the gross variance in body weight decreased with advancing age, whereas there was no change in variance for brain weight. The database contains some information to inform ethnic and gender differences in parameters; however, the majority of the published data pertain to Asian (mostly Japanese) and Caucasian males. As expected, the number of records tends to decrease with advancing age. In addition to a general lack of data for parameters in the elderly with various health conditions, there is also a dearth of information on blood and tissue composition in all elderly groups. Importantly, there are relatively few records for alveolar ventilation rate; therefore, the relationship between this parameter and cardiac output (usually assumed to be 1:1) in the elderly is not well informed by the database. Despite these limitations, the database represents a potentially useful resource for parameterizing PBPK models for the elderly to facilitate the prediction of dose metrics in older populations for application in risk assessment.

Although seafood contains a variety of arsenicals, including inorganic arsenic, which is toxic and carcinogenic, and arsenobetaine, which is considered nontoxic, the arsenic content of seafood commonly is reported only as total arsenic. A goal of this literature survey is to determine if generalizable values can be derived for the percentage of total arsenic in seafood that is inorganic arsenic. Generalizable values for percent inorganic arsenic are needed for use as default values in U.S. human health risk assessments of seafood from arsenic-contaminated sites. Data from the worldwide literature indicate the percent of inorganic arsenic in marine/estuarine finfish does not exceed 7.3% and in shellfish can reach 25% in organisms from presumably uncontaminated areas, with few data available for freshwater organisms. However, percentages can be much higher in organisms from contaminated areas and in seaweed. U.S. site-specific data for marine/estuarine finfish and shellfish are similar to the worldwide data, and for freshwater finfish indicate that the average percent inorganic arsenic is generally < 10%, but ranges up to nearly 30%. Derivation of nationwide defaults for percent inorganic arsenic in fish, shellfish, and seaweed collected from arsenic-contaminated areas in the United States is not supported by the surveyed literature.

Precise results (5% relative standard deviation, RSD) were found for NO sub(2) measurements from collocated Ogawa samplers. Reproducibility was also good for duplicate PE tubes for benzene, toluene, ethylbenzene, and xylene isomers (BTEX species, all , 6% RSD). As seen in previous studies, comparison of Ogawa NO sub(2) samplers with reference chemiluminescence measurements suggested good agreement. Generally good agreement was also found between the PE tubes and reference methods for BTEX species.

This paper describes the challenges associated with developing an analytical method for 14 PFAAs that will be used for drinking water occurrence monitoring. The method employs solid-phase extraction with analysis by liquid chromatography-tandem mass spectrometry (LC-MS-MS). The final method preservation scheme requires that samples be stored in polypropylene bottles and that they be buffered and free chlorine removed with Trizma buffer. Mean recoveries of chlorinated surface water samples fortified with the PFAAs at 40-100 ng/L (except for the perfluorooctane-sulfonamido-acetic acids at 200 ng/L) are 85-112% with < 5% relative standard deviation. Single laboratory minimum reporting limits of 2.9-14 ng/L are demonstrated with this methodology. The final method meets all of the EPA UCMR survey requirements for sample collection and storage, precision, accuracy, and sensitivity and is expected to be proposed for use under a future UCMR.

Methods: Two possible screening methods were considered for mold analysis: use of vacuum cleaner bag dust rather than the standard protocol dust samples and reducing the number of molds needed to be quantified resulting in the creation of an alternative mold burden scale. Results: Vacuum bag dust analysis placed the estimate of mold burden into the upper or lower half of the Environmental Relative Moldiness Index scale. Mold burdens estimated by only 12 species produced an index, the American Relative Moldiness Index, with a correlation of p = 0.80 with the Environmental Relative Moldiness Index. Conclusions: Two screening tools were developed for estimating the mold burden in homes.

Objectives: The objective of this study was to accurately measure and compare the concentrations of oxidative monoester phthalate metabolites in milk and surrogate fluids (serum, saliva, and urine) of 33 lactating North Carolina women. Methods: We analyzed serum, saliva, urine, and milk for the oxidative phthalate metabolites mono(3-carboxypropyl) phthalate, mono(2-ethyl-5-carboxypentyl) phthalate (MECPP), mono(2-ethyl-5-hydroxyhexyl) phthalate, and mono(2-ethyl-5-oxohexyl) phthalate using isotope-dilution high-performance liquid chromatography tandem mass spectroscopy. Because only urine lacks esterases, we analyzed it for the hydrolytic phthalate monoesters. Results: We detected phthalate metabolites in few milk ( 80% of serum samples, but other metabolites were less common (3-22%). Seven of the 10 urinary metabolites were detectable in greater than or equal to 85% of samples. Monoethyl phthalate had the highest mean concentration in urine. Metabolite concentrations differed by body fluid (urine > serum > milk and saliva). Questionnaire data suggest that frequent nail polish use, immuno-globulin A, and fasting serum glucose and triglyceride levels were increased among women with higher concentrations of urinary and/or serum phthalate metabolites; motor vehicle age was inversely correlated with certain urinary phthalate concentrations. Conclusions: Our data suggest that phthalate metabolites are most frequently detected in urine of lactating women and are less often detected in serum, milk, or saliva. Urinary phthalate concentrations reflect maternal exposure and do not represent the concentrations of oxidative metabolites in other body fluids, especially milk.

Typically, mixed cellulose ester (MCE, 0.45 or 0.8 mm pore size) and, to a much lesser extent, capillary-pore polycarbonate (PC, 0.4 mm pore size) membrane filters are used to collect airborne asbestos for count measurement and fiber size analysis. In this research study, chrysotile asbestos (fibers both shorter and longer than 5 mm) were generated in an aerosol chamber and sampled by 25 mm diameter MCE filter media to compare the fiber retention efficiency of 0.45 mm pore size filters vs. 0.8 mm pore size filter media. In addition, the effect of plasma etching times on fiber densities was evaluated. This study demonstrated a significant difference in fiber retention efficiency between 0.45 mm and 0.8 mm pore size MCE filters for asbestos aerosols (structures longer than or equal to 0.5 mm length). The fiber retention efficiency of a 0.45 mm pore size MCE filter is statistically significantly higher than that of the 0.8 mm pore size MCE filter. However, for asbestos structures longer than 5mm, there is no statistically significant difference between the fiber retention efficiencies of the 0.45 mm and 0.8 mm pore size MCE filters. The mean density of asbestos fibers (longer than or equal to 0.5 mm) increased with etching time. Doubling the etching time increased the asbestos filter loading in this study by an average of 13%. The amount of plasma etching time had no effect on the filter loading for fibers longer than 5 mm. Many asbestos exposure risk models attribute health effects to fibers longer than 5 mm. In these models, both the 0.45 mm and 0.8 mm pore size MCE filter can produce suitable estimates of the airborne asbestos concentrations. However, some models suggest a more significant role for asbestos fibers shorter than 5 mm. Exposure monitoring for these models should consider only the 0.45 mm pore size MCE filters as recommended by the U.S. Environmental Protection Agency Asbestos Hazard Emergency Response Act (AHERA) protocol and other methods.

Even with these networks, degradation rates across entire systems cannot readily be extrapolated from the samples. When organic compounds are degraded by microbes, especially nitrifying bacteria, oxides or nitrogen (NO sub(x)) are released to the atmosphere. Thus, the flux of nitric oxide (NO) from the soil to the lower troposphere can be used to predict the rate at which organic compounds are degraded. By characterizing and applying biogenic and anthropogenic processes in soils the rates of degradation of organic compounds. Toluene was selected as a representative of toxic aromatic compounds, since it is inherently toxic, it is a substituted benzene compound and is listed as a hazardous air pollutant under Section 12 of the Clean Air Act Amendments of 1990. Measured toluene concentrations in soil, microbial population growth and NO fluxes in chamber studies were used to develop and parameterize a numerical model based on carbon and nitrogen cycling. These measurements, in turn, were used as indicators of bioremediation of air toxic (i.e. toluene) concentrations. The model found that chemical concentration, soil microbial abundance, and NO production can be directly related to the experimental results (significant at P<0.01) for all toluene concentrations tested. This indicates that the model may prove useful in monitoring and predicting the fate of toxic aromatic contaminants in a complex soil system. It may also be useful in predicting the release of ozone precursors, such as changes in reservoirs of hydrocarbons and oxides of nitrogen. As such, the model may be a tool for decision makers in ozone non-attainment areas.

Time of day results indicated locomotion, tested in darkness (infrared), decreased gradually from early morning to a stable level between 13:00 and 15:30h. All further studies were conducted in early-to-late afternoon and lasted approximately 1h. Each study also began with a period of darkness to minimize any unintended stimulation caused by transferring the plates to the recording platform. Locomotion in darkness increased initially to a maximum at 4min, then decreased steadily to a low level by 20min. Locomotion during light was initially low and then gradually increased to a stable level after 20min. When 10-min periods of light and dark were alternated, activity was low in light and high in dark; curiously, activity during alternating dark periods was markedly higher than originally obtained during either extended dark or light. Further experiments explored the variables influencing this alternating pattern of activity. Varying the duration of the initial dark period (10-20min) did not affect subsequent activity in either light or dark. The activity increase on return to dark was, however, greater following 15min than 5min of light. Acute ethanol increased activity at 1 and 2% and severely decreased activity at 4%. One-percent ethanol retarded the transition in activity from dark to light, and the habituation of activity in dark, while 2% ethanol increased activity regardless of lighting condition. Collectively, these results show that locomotion in larval zebrafish can be reliably measured in a 96-well microtiter plate format, and is sensitive to time of day, lighting conditions, and ethanol.

OBJECTIVE: We hypothesized that DE inhalation would cause greater inflammation, hematologic alterations, and cardiac molecular impairment in spontaneously hypertensive (SH) rats than in healthy Wistar Kyoto (WKY) rats. METHODS AND RESULTS: Male rats (12-14 weeks of age) were exposed to air or DE from a 30-kW Deutz engine at 500 or 2,000 mu g/m super(3), 4 hr/day, 5 days/week for 4 weeks. Neutrophilic influx was noted in the lung lavage fluid of both strains, but injury markers were minimally changed. Particle-laden macrophages were apparent histologically in DE-exposed rats. Lower baseline cardiac anti-oxidant enzyme activities were present in SH than in WKY rats; however, no DE effects were noted. Cardiac mitochondrial aconitase activity decreased after DE exposure in both strains. Electron microscopy indicated abnormalities in cardiac mitochondria of control SH but no DE effects. Gene expression profiling demonstrated alterations in 377 genes by DE in WKY but none in SH rats. The direction of DE-induced changes in WKY mimicked expression pattern of control SH rats without DE. Most genes affected by DE were down-regulated in WKY. The same genes were down-regulated in SH without DE producing a hypertensive-like expression pattern. The down-regulated genes included those that regulate compensatory response, matrix metabolism, mitochondrial function, and oxidative stress response. No up-regulation of inflammatory genes was noted. CONCLUSIONS: We provide the evidence that DE inhalation produces a hypertensive-like cardiac gene expression pattern associated with mitochondrial oxidative stress in healthy rats.

The Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model is used to determine the back trajectory of air masses reaching the northeast by linking a downwind receptor to upwind source areas. The process analysis is applied to a high O sub(3) episode occurring on July 22, 2004 at three selected sites in the northeastern U.S. The process analysis at the location of the site shows that during the daytime, the O sub(3) concentrations in the surface layer are mainly enhanced by the vertical diffusion of O sub(3)-rich air from aloft, followed by horizontal advection (HADV) and chemical production (CHEM), whereas dry deposition (DDEP) and vertical advection (ZADV) mainly deplete O sub(3) concentrations at the sites of Valley Central (VC), NY and Castle Spring (CS), NH. By integrating the effects of each process over the depth of the daytime planetary boundary layer (PBL), it was found that at the VC site, CHEM and HADV contributed about 53% and 41%, respectively, to O sub(3) levels within the PBL. This confirms the significance of regional transport of O sub(3) from the industrialized areas into the Northeast. On the other hand, the process analysis results for O sub(3) formation in moving air masses indicate that on July 22, large chemical production of O sub(3) along the transport path over the polluted urban regions leads to significant increase in O sub(3) in the air mass reaching the VC site, whereas the low chemical production of O sub(3) along the transport path over the low emission regions leads to the low O sub(3) concentration at the site of Belleayre Mountain (BM), NY. The dramatic buildup of O sub(3) concentration from 50ppb to 102ppb in the air masses before reaching the VC site after 12:00 EST on 7/22 indicates the significant impact of pollution from the northeastern urban corridor at this site. On the basis of the results at the CS site, it was found that high NO sub(x) emissions along the transport path led to large chemical production of O sub(3) in the air mass reaching the CS site on July 22. In contrast, the low chemical production of O sub(3) associated with low emission (relatively clean conditions) along the transport path over the northern portions of the domain is responsible for the low O sub(3) concentration at the CS site on July 26.

This study presents the first evaluation of the performance of the Eta-CMAQ air quality forecast model to predict a variety of widely used seasonal mean and cumulative O sub(3) exposure indices associated with vegetation using the U.S. AIRNow O sub(3) observations. These exposure indices include two concentration-based O sub(3) indices, M7 and M12 (the seasonal means of daytime 7-h and 12-h O sub(3) concentrations, respectively), and three cumulative exposure-based indices, SUM06 (the sum of all hourly O sub(3) concentrations>=0.06ppm), W126 (hourly concentrations weighed by a sigmoidal weighting function), and AOT40 (O sub(3) concentrations accumulated over a threshold of 40ppb during daylight hours). During a three-month simulation (July-September 2005), the model over predicted the M7 and M12 values by 8-9ppb, or a NMB value of 19% and a NME value of 21%. The model predicts a central belt of high O sub(3) extending from Southern California to Middle Atlantic where the seasonal means, M7 and M12 (the seasonal means of daytime 7-h and 12-h O sub(3) concentrations), are higher than 50ppbv. In contrast, the model is less capable of reproducing the observed cumulative indices. For AOT40, SUM06 and W126, the NMB and NME values are two- to three-fold of that for M7, M12 or peak 8-h O sub(3) concentrations. The AOT40 values range from 2 to 33ppmh by the model and from 1 to 40ppmh by the monitors. There is a significantly higher AOT40 value experienced in the United States in comparison to Europe. The domain-wide mean SUM06 value is 14.4ppmh, which is about 30% higher than W126, and 40% higher than AOT40 calculated from the same 3-month hourly O sub(3) data. This suggests that SUM06 and W126 represent a more stringent standard than AOT40 if either the SUM06 or the W126 was used as a secondary O sub(3) standard. Although CMAQ considerably over predicts SUM06 and W126 values at the low end, the model under predicts the extreme high exposure values (>50ppmh). Most of these extreme high values are found at inland California sites. Based on our analysis, further improvement of the model is needed to better capture cumulative exposure indices.

The optical remote sensing (ORS) area source measurement method EPA OTM 10 was used to provide Hg super(0) flux data for the site. These results are reported and compared with cell room roof-vent monitoring data acquired by the facility for similar time periods. The 24-h extrapolated mercury emission rate estimates determined by the two monitoring approaches are shown to be similar with overall averages in the 400gday super(-) super(1) range with maximum values around 1200gday super(-) super(1). Results from the OTM 10 measurements, which include both cell room emissions and potential fugitive sources outside the cell room, are shown to be approximately 10% higher than cell room monitoring results indicating that fugitive emissions from outside the cell room produce a small but measurable effect for this site.

The Florida Keys National Marine Sanctuary (FKNMS) together with Monroe County have coordinated their actions to protect benthic habitats, improve water quality in the Sanctuary, and implement stormwater and wastewater infrastructure. Cooperation between the Sanctuary and Monroe County has resulted in the creation of No-Discharge Zones and public works projects both of which have succeeded in reducing pollutants into Sanctuary waters. Efforts to improve communication between the Sanctuary and County should still be made in order for improvements in water quality to be realized.

This study investigates the degradation of PCBs using sulfate radical-based advanced oxidation processes (SR-AOPs). These processes are based on the generation of sulfate radicals through iron (Fe(II), Fe(III)) mediated activation of peroxymonosulfate (KHSO sub(5), PMS) or persulfate (Na sub(2)S sub(2)O sub(8), PS). This study is the first instance for coupling of Fe(II)/Fe(III) with PMS for PCB degradation in aqueous and sediment systems. The high oxidation efficiencies of the free radicals (SO sub(4)[radical dot] super(-)), in combination with the slow rate of consumption of the oxidants, make these processes very effective for the degradation of recalcitrant organic compounds. The effectiveness of the process was evaluated based on the degradation of a model polychlorinated biphenyl, 2-chlorobiphenyl and total organic carbon (TOC) removal. The kinetics of 2-chlorobiphenyl degradation along with the effect of oxidant and catalyst concentrations on the degradation efficiency was studied. Near complete removal of 2-chlorobiphenyl was observed when Fe(II) was used with PMS or PS. Fe(II) acts as a sulfate radical scavenger at higher concentrations indicating that there is an optimum concentration of Fe(II) that leads to most effective degradation of the target contaminant. A chelating agent, sodium citrate, was used to control the quantity of iron in the solution for activation of the oxidant. For the first time, we studied the feasibility of the activation of PMS using iron citrate complexes for PCB degradation. In the presence of sodium citrate, increase in degradation efficiency was observed up to a metal:ligand ratio of 1:2, after which the increase in citrate concentration led to a decrease in removal efficiency. Fe(II)/PMS systems were found to be very effective in degrading PCB in a sediment-slurry system with more than 90% PCB removal being observed within 24 h.

These Ct values are generally derived from laboratory studies in which chlorine decay is characterized by a first order decay model. The concentration of chlorine is often only measured at the initial and final exposure times. In this study, using bacterial spore inactivation data where residual chlorine was measured at least twice in between initial and final exposure times, chlorine decay models were evaluated to determine the effect on Ct calculations. Traditionally Ct is treated as a constant in estimating the rate constant of the simple Chick-Watson inactivation kinetics model. As Ct is estimated it is subject to estimation error. To account for this error, the parameters of the chlorine decay and the inactivation models were estimated simultaneously.

The rate constants determined using these techniques were compared to each other and to values reported in the literature. Difference factors between kOH obtained using UV/H2O2 and pulse radiolysis ranged from 1.1 to 4.7. It was shown that even small differences in hydroxyl radical rate constants values can result in fairly large differences (up to 50%) when trying to predict removals of pollutants in an advanced oxidation process.

After re-evaluation of the selected remedy for groundwater, pump and treat, EPA changed the remediation approach to in-situ chemical oxidation (ISCO) through an Amended Record of Decision in September 2007. At that time, EPA established a goal for the site to attain construction complete status within one year, by September 30, 2008. Activated persulfate was selected as the chemical oxidant for its capability to oxidize 1,4-dioxane, in addition to the other VOC contaminants of concern. Bench-scale and field pilot scale test were completed for three areas of the site to collect site-specific information to evaluate persulfate's ability to destroy the contaminants of concern and to optimize full-scale remediation design in three discrete source areas at the site. Base-activated persulfate was injected in Areas A and B in December 2007, and pilot test injection was completed in Area C in early February 2008, after vertical profiling was completed throughout Area C. Groundwater sampling for laboratory analysis was planned for 6 and 12 weeks after injection in each area; however, it was known during pilot test planning that the full-scale design would need to be completed by the end of March 2008, before all laboratory results would be available. In order to complete the design, an intensive evaluation of field geochemistry parameters and field screening chemical analysis was performed to assess radius of influence, oxidant persistence, and aquifer behavior. Field screening analyses included residual persulfate via a permanganate titration, sulfate via colorimetry, and sodium via an ion-selective electrode. The field screening and field geochemistry results were used heavily in completing the full-scale ISCO design. The laboratory analytical results noted significant decreases in concentrations of chemicals of concern in wells where geochemistry and field parameters were observed to change. This article discusses pilot test planning, performance monitoring, and full-scale design using data collected from the pilot test for this fast-track remediation. The full-scale application was completed between July and September 2008, and was the largest persulfate ISCO injection performed to date.

In order to understand these relationships, intermediates and dechlorination pathways of carefully selected 17 congeners were investigated with reactive Pd/Mg systems that bring about their rapid and complete dechlorination. The preferential site of electrophilic attack and its mechanistic aspects were interpreted in terms of steric, inductive, and resonance stabilization. The trends for electrophilic substitution were consistently p- > m- > o- positions indicating that more toxic 'coplanar' PCB congeners were easily reduced. The dechlorination rates and pathways were influenced both by inductive effect of Cl that likely governs the stability of the intermediate arenium ion and by steric effects primarily effecting the adsorption step (especially for the o-congeners). Electrophilic attack occurred preferentially on the less substituted phenyl ring in absence of steric effects. A distinct correlation between rate of HDCl and the degree of chlorination was not observed, rather it depended on positions of Cl with respect to the biphenyl bond, and the dominance between counteracting factors of deactivation by subsequent chlorinations and improvement in probability of dechlorination through increased number of Cls.

AN - 69829858; 18851987 AB - Induction of airway hyperresponsiveness and asthma from formaldehyde inhalation exposure remains a debated and controversial issue. Yet, recent evidences on pulmonary biology and the pharmacokinetics and toxicity of formaldehyde lend support for such adverse effects. Specifically, altered thiol biology from accelerated enzymatic reduction of the endogenous bronchodilator S-nitrosoglutathione and pulmonary inflammation from involvement of Th2-mediated immune responses might serve as key events and cooperate in airway pathophysiology. Understanding what role these mechanisms play in various species and lifestages (e.g., child vs. adult) could be crucial for making more meaningful inter- and intra-species dosimetric extrapolations in human health risk assessment.

AN - 66665168; 19174897 AB - The SPARC vapor pressure and activity coefficient models were coupled to successfully estimate Henry's Law Constant (HLC) in water and in hexadecane for a wide range of organic compounds without modification to, or additional parametrization of, either SPARC model. The vapor pressure model quantifies the solute-solute intermolecular interactions in the pure liquid phase, whereas the activity coefficient model quantifies the solute-solvent and solvent-solvent (in addition to the solute-solute) interactions upon placing solute, i, in solvent, j. These intermolecular interactions are factored into dispersion, induction, dipole-dipole, and H-bonding components upon moving a solute molecule from the gas to the liquid phase. The SPARC HLC calculator so produced was tested and validated on the largest experimental HLC data set to date: 1356 organic solutes, spanning a wide range of functional groups, dipolarities and H-bonding capabilities, such as PAHs, PCBs,VOCs, amides, pesticides, and pharmaceuticals. The rms deviation errors for the calculated versus experimental log HLCs for 1222 compounds in water and 563 in hexadecane were 0.456 and 0.192 log [(mol/L)/(mol/L)] units, respectively, spanning a range of more than 13 and 20 log HLC dimensionless units for the compounds in water and hexadecane, respectively.

8800564 AB - Exposure to particulate matter (PM) is associated with increased cardiopulmonary morbidity and mortality. Diesel exhaust particles (DEP) are a major component of ambient PM and may contribute to PM-induced pulmonary inflammation. Proinflammatory signaling is mediated by phosphorylation-dependent signaling pathways whose activation is opposed by the activity of protein tyrosine phosphatases (PTPases) which thereby function to maintain signaling quiescence. PTPases contain an invariant catalytic cysteine that is susceptible to electrophilic attack. DEP contain electrophilic oxy-organic compounds that may contribute to the oxidant effects of PM. Therefore, we hypothesized that exposure to DEP impairs PTPase activity allowing for unopposed basal kinase activity. Here we report that exposure to 30 kg/cm super(2) DEP for 4 h induces differential activation of signaling in primary cultures of human airway epithelial cells (HAEC), a primary target cell in PM inhalation. In-gel kinase activity assay of HAEC exposed to DEPs of low (L-DEP), intermediate (I-DEP) or high (H-DEP) organic content showed differential activation of intracellular kinases. Exposure to these DEP also induced varying levels of phosphorylation of the receptor tyrosine kinase EGFR in a manner that requires EGFR kinase activity but does not involve receptor dimerization. We demonstrate that treatment with DEP results in an impairment of total and EGFR-directed PTPase activity in HAEC with a potency that is independent of the organic content of these particles. These data show that DEP-induced EGFR phosphorylation in HAEC is the result of a loss of PTPase activities which normally function to dephosphorylate EGFR in opposition to baseline EGFR kinase activity.

Six particle size fractions were characterized with diameter (Dp) < 1.8 *mm; the smallest size fraction was 0.056 < Dp < 0.1 *mm which accounts for the majority of the mass in the ultrafine (PM0.1) size range. Source profiles for ultrafine particles developed during previous studies were applied to the measurements at each sampling site to calculate source contributions to organic carbon (OC) and elemental carbon (EC) concentrations. Ultrafine EC concentrations ranged from 0.03 *mg m-3 during the daytime to 0.18 *mg m-3 during the nighttime. Gasoline fuel, diesel fuel, and lubricating oil combustion products accounted for the majority of the ultrafine EC concentrations, with relatively minor contributions from biomass combustion and meat cooking. Ultrafine OC concentrations ranged from 0.2 *mg m-3 during the daytime to 0.8 *mg m-3 during the nighttime. Wood combustion was found to be the largest source of ultrafine OC. Meat cooking was also identified as a significant potential source of PM0.1 mass but further study is required to verify the contributions from this source. Gasoline fuel, diesel fuel, and lubricating oil combustion products made minor contributions to PM0.1 OC mass. Total ultrafine particulate matter concentrations were dominated by contributions from wood combustion and meat cooking during the current study. Future inhalation exposure studies may wish to target these sources as potential causes of adverse health effects.

The main objective of this experiment was to determine the source of GPR reflections from a changing water table in a controlled experimental environment. During the experiment, the water table was varied by injecting water into the bottom of the tank and subsequently draining it. The experiment was conducted over a number of days, during which various conditions (unsaturated, saturated, residual saturation) were characterized using GPR measurements. As a result of this approach, a more comprehensive comparison was possible for each step and results were compared with mass balance information. Results of the study indicate that, under saturated conditions, the main reflector of GPR energy is indicative of the capillary fringe and not the actual water table. Well readings and estimates of the mass balance of water input into the system confirm this interpretation.

AN - 69919215; 19025790 AB - This overview paper provides the historical context for the incorporation of lifestage-specific concerns in human health risk assessment, briefly explains the process employed in a lifestage framework for risk assessment, and discusses the scientific rationale for how utilizing lifestage data will strengthen the overall risk assessment process. This risk assessment approach will add value by: (1) providing a more complete evaluation of the potential for vulnerability at different lifestages, including a focus on the underlying biological events and incorporation of mode of action information related to different critical developmental periods; (2) evaluating the potential for toxicity during all lifestages after early lifestage exposure; (3) reviewing the importance of integrating exposure information and adverse health effects across lifestages; and (4) serving as a basis to extend some aspects of the children's health risk assessment framework to all lifestages.

AN - 69916567; 19094080 AB - Hypothyroidism during pregnancy and the early postnatal period has severe neurological consequences for the developing offspring. The impact of milder degrees of perturbation of the thyroid axis as encompassed in conditions of subclinical hypothyroidism and hypothyroxinemia, however, has not been established. The present investigation examined the effects of graded levels of hypothyroidism, from subclinical to severe, on global gene expression in the developing rodent brain. Thyroid hormone insufficiency was induced by administration of propylthiouracil (PTU) to pregnant rats via drinking water from gestational day 6 until sacrifice of pups prior to weaning. In the first study a specialised microarray, the Affymetrix Rat Neurobiology array RN_U34, was used to contrast gene expression in the hippocampus of animals exposed to 0 or 10 ppm (10 mg/l) PTU, a treatment producing severe hypothyroidism. In the second study, a more complete genome array (Affymetrix Rat 230A) was used to compare gene expression in the neocortex and hippocampus of postnatal day (PN) 14 animals experiencing graded degrees of thyroid hormone insufficiency induced by delivery of 0, 1, 2 or 3 ppm PTU to the dam. Dose-dependent up- and down-regulation were observed for gene transcripts known to play critical roles in brain development and brain function. Expression levels of a subset of approximately 25 genes in each brain region were altered at a dose of PTU (1 ppm) that induced mild hypothyroxinemia in dams and pups. These data indicate that genes driving important developmental processes are sensitive to relatively modest perturbations of the thyroid axis, and that the level of gene expression is related to the degree of hormone reduction. Altered patterns of gene expression during critical windows of brain development indicate that thyroid disease must be viewed as a continuum and that conditions typically considered 'subclinical' may induce structural and functional abnormalities in the developing central nervous system.

AN - 69916129; 19025791 AB - Understanding and characterizing risks to children has been the focus of considerable research efforts at the U.S. Environmental Protection Agency (EPA). Potential health risks resulting from environmental exposures before conception and during pre- and postnatal development are often difficult to recognize and assess because of a potential time lag between the relevant periods of exposure during development and associated outcomes that may be expressed at later lifestages. Recognizing this challenge, a lifestage approach for assessing exposure and risk is presented in the recent EPA report titled A Framework for Assessing Health Risks of Environmental Exposures to Children (U.S. EPA, 2006). This EPA report emphasizes the need to account for the potential exposures to environmental agents during all stages of development, and consideration of the relevant adverse health outcomes that may occur as a result of such exposures. It identifies lifestage-specific issues associated with exposure characterization for regulatory risk assessment, summarizes the lifestage-specific approach to exposure characterization presented in the Framework, and discusses emerging research needs for exposure characterization in the larger public-health context. This lifestage approach for characterizing children's exposures to environmental contaminants ensures a more complete evaluation of the potential for vulnerability and exposure of sensitive populations throughout the life cycle.

AN - 69913645; 19085945 AB - In 2006, the U.S. EPA published a report entitled A Framework for Assessing Health Risks of Environmental Exposures to Children (hereafter referred to as the "Framework") describing a lifestage approach to risk assessment that includes the evaluation of existing data from a temporal perspective (i.e., the timing of both the exposure and the outcome). This article summarizes the lifestage-specific issues discussed in the Framework related to the qualitative and the quantitative hazard and dose-response characterization. Lifestage-specific hazard characterization includes an evaluation of relevant human and experimental animal studies, focusing on the identification of critical windows of development (i.e., exposure intervals of maximum susceptibility) for observed outcomes, evaluation of differential exposure at individual lifestages, the relevance and impact of lifestage-specific toxicokinetic and toxicodynamic data, mode of action information, variability and latency of effects from early lifestage exposure, and describing uncertainties. The interpretation of the hazard data to determine the strength of association between early life exposures and the timing and type of outcomes depends upon the overall weight of evidence. Lifestage-specific dose-response characterization relies on the identification of susceptible lifestages in order to quantify health risk, information on the point of departure, key default assumptions, and descriptions of uncertainty, sensitivity, and variability. Discussion of the strength and limitations of the hazard and dose-response data provides a basis for confidence in risk determinations. Applying a lifestage approach to hazard and dose-response characterization is likely to improve children's health risk assessment by identifying data gaps and providing a better understanding of sources of uncertainty.

AN - 69821355; 19031383 AB - An extensive review of CDC epidemiological responses to human outbreaks of anthrax from occupational settings between the years of 1950 and 2001 documented a variety of approaches to mitigation and decontamination [2]. These approaches included taking no action, burning contaminated materials, chlorinating water supplies, instituting administrative and engineering controls and PPE, vaccinating potentially exposed individuals, and in 2 instances, fumigating with formaldehyde vapor (now considered to be a human carcinogen). Secondary contamination of a worker's home was documented in 1 case, but not felt to be clinically significant to warrant any decontamination efforts. In response to the B. anthracis attacks in 2001, chlorine dioxide fumigation, vaporous hydrogen peroxide fumigation, and a combination of HEPA vacuuming, cleaning, and bleach application were all techniques used successfully to clean B. anthracis spore contamination.

AN - 69785663; 18791183 AB - The applications of systems biology approaches have greatly increased in the past decade largely as a consequence of the human genome project and technological advances in genomics and proteomics. Systems approaches have been used in the medical and pharmaceutical realm for diagnostic purposes and target identification. During this same period, the use of mode of action (MOA) for risk assessment has been increasing and there is a need for quantitative risk assessments on an ever-growing number of environmental chemicals. Genome-wide (i.e., global) measurements provide both a discovery engine for identifying MOA and an information base for subsequent evaluation of MOA when conducting a risk assessment. These genome-wide measurements are not chosen based on the hypothesized MOA and therefore represent an unbiased check of the comprehensiveness of an MOA. In addition, optimal design for MOA studies is critical to provide the time and dose dependent data required for quantitative model building. Finally, identification of biomarkers and bioindicators of disease in humans provides a viable way to extrapolate from disease outcomes measured at high exposure levels to those at low exposure levels and thus provide the opportunity to reduce or perhaps eliminate in vivo animal testing. To realize the full potential of these approaches, larger integrated projects which include all these individual components are necessary.

AN - 69781605; 18806252 AB - Animal models are needed to assess novel proteins produced through biotechnology for potential dietary allergenicity. Currently proposed rodent models evaluate sensitizing potential of food extracts or proteins following parenteral administration or oral administration with adjuvant. However, food allergy requires not only the potential to induce immunoglobulin (Ig) E but also the capacity to avoid induction of oral tolerance (specific inhibition of IgE production). Here we describe a mouse model that assesses the potential of food extracts to induce oral tolerance. Adult C3H/HeJ mice were exposed orally to food extracts (without adjuvant) and subsequently challenged with the extract ip. Reduction of antigen-specific serum IgE relative to appropriate controls was used to indicate tolerance. Foods associated with persistent, severe allergy (peanut, Brazil nut), and nonallergens (turkey, spinach) were less tolerizing than foods associated with frequently resolving allergy (egg white). Digestibility was assessed in vitro, and pH alterations or encapsulation were used to modify solubility or digestibility. Egg white, peanut, and Brazil nut proteins were resistant to gastric enzyme (pepsin) degradation; turkey and spinach were not. Among pepsin-resistant proteins, peanut and Brazil nut appeared more sensitive to intestinal enzyme than egg white. For the extracts tested, full gastric digestion appeared to prevent induction of tolerance. Once through the stomach, only proteins resistant to intestinal enzymes induced tolerance. Limiting gastric digestion with sodium bicarbonate enhanced tolerance to peanut and Brazil nut. This model represents a complementary method of assessing potential allergenicity. Also, the conditions under which the test protein is encountered may impact experimental outcome.

AN - 69742686; 18953671 AB - This study ascertains the effects of zinc, a major component of particulate matter, on pulmonary and systemic endpoints using hyperlipidemic rabbits to model diet-induced human atherosclerosis. New Zealand White rabbits were fed a normal or cholesterol-enriched diet and then were intratracheally instilled 1x/week for 4 weeks with saline or 16 microg/kg of zinc, equal parts sulfate and oxide. Physiologic responses, blood after each exposure, and terminal bronchoalveolar lavage (BAL) were assessed. Rabbits fed a cholesterol-rich diet developed hyperlipidemia and had consistently higher circulating leukocyte counts than rabbits fed normal chow. Within minutes after zinc instillation, saturation of peripheral oxygen was decreased in hyperlipidemic rabbits and heart rate was increased in hyperlipidemic rabbits with total serum cholesterol levels greater than 200 mg/dl. Total circulating leukocytes levels were increased 24 h after the first zinc instillation, but upon repeated exposures this effect was attenuated. After repeated zinc exposures, BAL fluid (BALF) N-acetylglucosaminidase activity was increased regardless of hyperlipidemic state. Hyperlipidemic rabbits had an increase in BALF-oxidized glutathione and a decrease in serum nitrite. The study elucidates mechanisms by which the zinc metal component of PM drives cardiovascular health effects, as well as the possible susceptibility induced by hyperlipidemia. Furthermore, the study exemplifies the benefits of monitoring circulatory physiology during exposure as well as after exposure.

AN - 66698218; 19263881 AB - Aquatic insects provide a critical energy subsidy to riparian food webs, yet their role as vectors of contaminants to terrestrial ecosystems is poorly understood. We investigated relationships between aquatic resource utilization and contaminant exposure for a riparian invertivore assemblage (spiders and herptiles) along a stream contaminated with polychlorinated biphenyls (PCBs). Stable carbon (delta13C) and nitrogen (delta15N) isotopes indicated that aquatic insect utilization varied among predators, with progressive enrichment of delta13C and depletion of delta15N as predators shifted from aquatic to terrestrial prey. PCB concentrations significantly increased along these isotopic gradients; delta13C and delta15N explained 65% and 15% of the variance in predator sigmaPCBs, respectively. PCBs in predators were high, exceeding 2000 ng/g wet mass (the human-health advisory prohibiting any consumption of fish tissue) in three species. Greater consideration should be given to streams as lateral exporters rather than simply as longitudinal conduits for contaminants. Persistent contaminants are underutilized for addressing landscape-level questions in subsidy research, but our results demonstrate they are an ideal in situ tracer of stream-derived energy because they label stream organic matter and invertebrates over large distances. Likewise, riparian predators such as tetragnathid spiders have great potential as biological monitors of stream condition and as an assessment tool for risk management of contaminated aquatic sediments.

Seepage faces and bank slopes ranging from 1/3 to 100/3 were simulated. The initial conditions were assumed steady-state flow with water draining toward the stream. Then, the stream level rose at a constant rate to the specified elevation of the water table given by the landward boundary condition and stayed there until the system reached a new steady state. This represents a highly simplified version of a real world hydrograph. For the specific examples considered, the following conclusions can be made. The volume of surface water entering the bank increased with the rate of stream level rise, became negligible when the rate of rise was slow, and approached a positive constant when the rate was large. Also, the volume decreased with the dimensionless parameter M (the product of the anisotropy ratio and the square of the domain's aspect ratio). When M was large (>10), bank storage was small because most pore space was initially saturated with ground water due to the presence of a significant seepage face. When M was small, the seepage face became insignificant and capillarity began to play a role. The weaker the capillary effect, the easier for surface water to enter the bank. The effect of the capillary forces on the volume of surface water entering the bank was significant and could not be neglected.

Stream restoration has become increasingly popular, yet efforts to quantify N-removal benefits are only just beginning. Natural resource managers are asking scientists to provide advice for reducing the downstream flux of N. Here, we propose a framework for prioritizing restoration sites that involves identifying where potential N loads are large due to sizeable sources and efficient delivery to streams, and when the majority of N is exported. Small streams (1st-3rd order) with considerable loads delivered during low to moderate flows offer the greatest opportunities for N removal. We suggest approaches that increase in-stream carbon availability, contact between the water and benthos, and connections between streams and adjacent terrestrial environments. Because of uncertainties concerning the magnitude of N reduction possible, potential approaches should be tested in various landscape contexts; until more is known, stream restoration alone is not appropriate for compensatory mitigation and should be seen as complementary to land-based best management practices.

But the task will not be as simple as 'If you build it, they will come.' The key to understanding the status of and prospects for official material flow accounts in the United States is to see the picture from the point of view of public sector and environmental innovation generally, rather than from the point of view of building the details of the accounts themselves. A simple model of public sector innovation helps explain what is happening and what needs to happen to make further progress. The model used here has four principal elements: methods, organizational capacity, demand, and actual use. The details and sequence of these elements vary in different situations, but all four must be present for successful innovations. Although aspects of culture, innovation, and government bureaucracy differ from country to country, the basic model appears to be similar across borders, at least in countries belonging to the Organisation for Economic Cooperation and Development (OECD). Seen this way, recent events in the United States indicate that (1) there is significant potential for such accounts; (2) the United States is moving toward creating them, although not in a systematic manner, which means that the progression and eventual outcome are uncertain; and (3) there are ways for the research community to participate very positively in the public process.

Progressive technology demonstrations by the MWTP over the past 15 years have resulted in improved operation of sulfate-reducing bacteria (SRB) bioreactors. Although using SRB to treat ARD is now fairly widespread, it was uncommon in the early 1990s when the MWTP used this innovative biotechnology. The first and longest running demonstration was an in situ bioreactor installed within the flooded subsurface workings of the Lilly/Orphan Boy Mine in 1994. The second project, at the Calliope Mine, compared the performance of several SRB bioreactor configurations and operational attributes, including lime pretreatment and reactor temperature. The third demonstration, at the Golden Sunlight Mine, consisted of two treatment steps with a recycle stream. The fourth project was an investigation of existing bioreactor designs and resulted in an improved bioreactor configuration. Significant findings included: (1) a mineshaft could be used as a long-term, in situ bioreactor, (2) SRB thrive in temperature extremes, (3) sulfide recycle effectively avoids contact of ARD with bacterial populations, and (4) ideal bioreactor substrate provides short-term and long-term nutrients, good support matrix, and enhanced permeability.

However, little is known about how temporal resolution of transient data and climate variability may color these potential indicators of hydrologic pattern or condition. Warm-season stream stage and rainfall were monitored continuously (5 min) during the 2002 water year in eight tributaries of the Little Miami River (Ohio), which drain 17-58 km super(2) catchments. Rise rates generated using 5-min data were different than those generated with mean daily data [calculated with the Indicators of Hydrologic Alteration (IHA) software], though fall rates were similar for fine and coarse temporal data. This result suggests that data with low temporal resolution may not be adequate to fully represent the dynamics of storm rise rates. Conversely, fall rates based on daily stage data (via IHA) were similar to those based on the 5-min data, and so daily mean data may be appropriate for characterizing fall rates. We next analyzed the possible correlations between rainfall variability and storm-flow stage dynamics. We derived rise and recession rates from storm stage hydrographs by assuming exponential rise and decay of a runoff peak. We found that raw rise rates (R sub(raw)) were correlated with both the maximum rainfall rate and the time to the centroid of a rain event. We subsequently removed the trend based on these rainfall characteristics, which yielded new representations of rise rates abbreviated as R sub(rate) and R sub(tcent), respectively, and that had lower variability than the uncorrected (raw) data. Fall rates were found to be independent of rainfall characteristics. Due to the predominant influence of stream hydrology upon aquatic biota and nutrient fluxes, our work suggests that these stage data analysis protocols can refine or otherwise reduce variability in these indices by accounting for relevant factors such as rainfall forcing. These protocols for derivation of transient indices should be tested for their potential to improve correlations between stream hydrology and temporally aligned biotic data and dissolved nutrient fluxes in streams.

As the liquid biofuels industry transitions to lignocellulosic feedstocks, expands the end-product portfolio to include other alcohols, and encounters more dilute alcohol concentrations, alternative separation technologies which are more energy efficient than the conventional approach will be in demand. In this review, alcohol recovery technology options and alcohol dehydration technology options for the production of ethanol and 1-butanol are reviewed and compared, with an emphasis on the energy footprint of each approach. Select hybrid technologies are also described. Published in 2008 by John Wiley & Sons, Ltd.

The conversion of forested landscapes to agriculture and, increasingly, to suburban and urban development significantly affects the structure and function of both terrestrial and aquatic ecosystems. While a growing body of research is examining how biotic communities change in response to human alteration of landscapes, less is known about how these changes in community structure affect biotic interactions.2. The objective of this study was to examine top-down control by macroconsumers (fish and crayfish) across a human-impacted landscape. We predicted that changes in stream macroconsumers and physicochemical characteristics associated with increased catchment development (e.g. decreased abundance of fish that are obligate benthic invertivores, increased sedimentation) would diminish top-down control of benthic insects. We expected that effects on algal assemblages would be more variable, with increased top-down control at sites dominated by algivorous fish and diminished control elsewhere. To test these predictions, we experimentally excluded fish and crayfish from areas of the bed of five streams whose catchments ranged from 100% to <50% forested, and examined the effects of exclusion on benthic insects and algae.3. Despite cross-site differences in physical, chemical and biological characteristics, the outcome of our experiments was consistent across five sites representing a range of catchment development. Across all sites, macroconsumers reduced total insect biomass, largely due to decreases in Chironomidae and Hydropsychidae larvae. Macroconsumers also affected algal assemblages, reducing chlorophyll-a and the proportion of upright and filamentous diatoms (e.g. Melosira, Cymbella) but increasing the proportion of adnate diatoms (e.g. Achnanthes) across all sites.4. We expected that differences in factors such as macroconsumer assemblage composition, nutrient and light availability and sedimentation would result in variable responses to macroconsumer exclusion in the five streams. Contrary to these expectations, only one response variable (ash-free dry mass) showed a statistically significant interaction (i.e. siteexclusion) effect. Most responses to exclusion were relatively consistent, suggesting functional redundancy in assemblages of macroconsumers among the sites despite differences in catchment land use.

We used data from the western stream and river survey of the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program to estimate the surface area of flowing waters occupied by nonnative fish and amphibian species at three spatial scales. For the 12-state survey area, an estimated 75% of the surface area of the target stream network had one or more nonnative fish or amphibian species, compared with 52% of the stream length. At all spatial scales (except the state of Washington), the estimates of the proportion of surface area with nonnatives were larger than those for estimated stream length. The relative extent of occupancy for individual species often differed depending on how they were assessed. For example, when assessed by length of network occupied, brook trout Salvelinus fontinalis was the most widespread nonnative fish (17%) but dropped to ninth position when assessed by surface area occupied (7%), while common carp Cyprinus carpio went from fourth position (10% of stream length) to second position when assessed by surface area occupied (27%). Estimates of the surface areas of flowing waters occupied by nonnative species are useful and easily calculated additions to the ways in which probability-based surveys can assess the condition of the resource.

Recently, federal and state agencies have shown increased interest in developing sediment criteria to maintain or improve habitat quality for the protection of aquatic species. To develop biologically based sediment criteria, sediment amounts must be linked with aquatic vertebrate response. For our analysis, we related an aquatic vertebrate index of biotic integrity (IBI) with a measure of the areal percentage of streambed surficial fines ([imgchar=http://afs.allenpress.com/charent/iso_characters_mixed/l o wercase/le.gif]0.06 mm). The association suggested that fine sediment limits the biological potential of mountain streams. We used quantile regression to model the upper limit of IBI response; the regression equation predicted a 4.7% decline in IBI for each 10% increase in areal surficial fines. However, the limiting relationship itself did not suggest a specific sediment level above which impairment was evident. To develop more specific evidence regarding sediment impairment and to describe possible impairment thresholds along the continuous relationship, we sought additional information from (1) the range of areal percent fines at the 169 least disturbed reference sites in our sample, (2) sediment tolerance values calculated for sediment-sensitive salmonids in the Mountains ecoregion, (3) a review of studies that describe IBI scores representing very good to excellent condition in coldwater (trout) streams of the United States, and (4) a second literature review of laboratory and field research relating the effects of sediment on the survival of salmonid eggs. Placing our initial results in the context of this additional information, we concluded that streambed areal surficial fine sediment (particle size [imgchar=http://afs.allenpress.com/charent/iso_characters_mixed/lo w ercase/le.gif] 0.06 mm) levels of 5% or less retain habitat potential for sediment-sensitive aquatic vertebrates in mountain streams. We offer these results as scientific guidance for the process of establishing sediment criteria.

On average, approximately 40,000 females breed annually on this 1.8 km nesting beach in remote north Queensland. The population is characterized by a declining size of the annual nesting population, reducing size of the breeding females, extremely poor nesting success, reduced number of clutches per season and high egg mortality. The poor nesting success, reduced number of clutches per season and high egg mortality are the result of environmental parameters at the island. This nesting population migrates from dispersed foraging areas with a 2,500 km radius. Over recent decades, this stock has been subjected to a regular substantial harvest of principally large females over an extended part of its foraging range in northern Australia, eastern Indonesia and southern Papua, New Guinea. Under current environmental conditions and management practices, this very large C. mydas population is on track for a significant population decline within the next few decades (in less than one generation). This decline also threatens the continuity of culturally significant linkages between indigenous coastal communities and green turtles in Torres Strait, northern Australia and southern New Guinea.

Emphasis has been on tagging census and associated intra- and inter-seasonal recaptures and embryology, temperature dependent sex determination, growth, migration and dispersal, diet, population genetics and population dynamics studies, Immature Caretta are tracked from recruitment from oceanic waters through 13 yr of growth to their first breeding migrations. First breeding occurs at about 30 yr. On average, females at first breeding are smaller, lay fewer and smaller clutches and have longer remigration intervals than in later breeding seasons over the next 20-30 yr. Breeding populations have declined by 86% since the 1970s, mostly from the result of fisheries bycatch. Fox predation of eggs was intense at the beaches that incubate most of the female hatchlings from the late 1970s to mid 1980s. The impact of this egg mortality is expected to be seen as reduced recruitment to the currently depleted adult population within the next few years. With TEDs now operational in the trawl fisheries since 2000, this mortality factor should be largely eliminated. Fox baiting programs have reduced egg loss to foxes to a trivial level since the late 1980s. Hatchling production at Mon Repos, a female producing beach, has been substantially enhanced by rescuing doomed eggs since 61990. Monitoring the impact of TEDs, fox control management and hatchling enhancement on eastern Australian Caretta population dynamics is ongoing.

The assessment was led by the EPA Office of Water, in cooperation with EPA regions, states, tribal nations, and the EPA Office of Research and Development (ORD). The WSA was implemented as 2 large-scale regional surveys of streams and rivers. Both studies used EPA's River Reach File (RF3) as the basis for the sample frame. The Environmental Monitoring and Assessment Program (EMAP) Western Pilot Study, conducted by ORD in cooperation with EPA Regions 8, 9, and 10 and 12 western states, assessed all streams and rivers in the 12 western states (EMAP-West). A stratified, unequal probability survey design (50 sites/state and additional sites in 5 intensive study areas) was used to select sites from all streams and river segments coded as perennial in RF3. The unequal selection depended on Strahler order, aggregated Omernik level III ecoregion, and special study region. The WSA study used the EMAP-West wadeable streams (WSA-West) and implemented a new design for the remaining 36 eastern conterminous states (WSA-East). The WSA-East design was an unequal probability survey design with unequal selection depending on Strahler order, Omernik Level II ecoregion, and EPA region. RF3 includes 5.29 million km of rivers and streams, of which 39% (2.07 million km) are coded as perennial. The WSA sample frame included 2.84 million km of streams (54% of the total length in RF3), of which 2.24 million km were in WSA-East and 0.60 million km were in WSA-West. Each selected site was classified on the basis of wadeability and the presence of flowing water. The estimated length of wadeable streams and rivers in the 48 conterminous states was 1.30 c 0.025 (SE) million km (45.7 c 1.1% of the stream length in the sample frame). Of this wadeable stream length, 78.6 c 1.0% (1.02 million km) was estimated to be appropriate for sampling. Nationally, 11.5 c 0.8% and 5.2 c 0.6% of this length could not be sampled because of access denial or physical inaccessibility, respectively. The proportion of length affected by access denial was higher in Southern Plains, Northern Plains, and Xeric West aggregated ecoregions, whereas stream length affected by physical inaccessibility was greatest in the Western Mountains aggregated ecoregion. Improvements in the sample frame (RF3 and its successors National Hydrography Database [NHD] and NHD-Plus) would reduce field costs for national surveys.

Information provided in the assessment filled an important gap in meeting the requirements of the US Clean Water Act. The purpose of the WSA was to: 1) report on the ecological condition of all wadeable, perennial streams and rivers within the conterminous US, 2) describe the biological condition of these systems with direct measures of aquatic life, and 3) identify and rank the relative importance of chemical and physical stressors affecting stream and river condition. The assessment included perennial wadeable streams and rivers that accounted for 95% of the length of flowing waters in the US. The US Environmental Protection Agency, states, and tribes collected chemical, physical, and biological data at 1392 randomly selected sites. Nationally, 42% of the length of US streams was in poor condition compared to best available reference sites in their ecoregions, 25% was in fair condition, and 28% was in good condition. Results were reported for 3 major regions: Eastern Highlands, Plains and Lowlands, and West. In the West, 45% of the length of wadeable flowing waters was in good condition. In the Eastern Highlands, only 18% of the length of wadeable streams and rivers was in good condition and 52% was in poor condition. In the Plains and Lowlands, almost 30% of the length of wadeable streams and rivers was in good condition and 40% was in poor condition. The most widespread stressors observed nationally and in each of the 3 major regions were N, P, riparian disturbance, and streambed sediments. Excess nutrients and excess streambed sediments had the highest impact on biological condition; streams scoring poor for these stressors were at 2 to 3 higher risk of having poor biological condition than were streams that scored in the good range for the same stressors.

9076478 AB - In 1972, the US Congress enacted the Clean Water Act (CWA) to protect US water resources. A critical section (305[b]) of the CWA calls for periodic accounting of the success or failure of efforts to protect and restore US waters. Over the years, several groups have reviewed the available data and concluded that they do not adequately describe the condition of US waters. The Wadeable Streams Assessment presents the first set of results from what will be a long-term partnership between the US Environmental Protection Agency, the individual states, tribal nations, and other federal agencies. The goal of this partnership is to fill critical information gaps that remain a deterrent to our ability to determine whether our policies and investments have resulted in improvement of US water resources.

One tool of this revised strategy is use of statistically based surveys of aquatic resources such as lakes, wetlands, rivers, and streams. Implementing large-extent surveys involves decisions that reflect compromises between scientific rigor, consistent and practical implementation over large areas and many participants, and the realities of time and money. Primary constraints result from interactions among management objectives, time lines, funding, and institutional constraints of participants. Secondary constraints arise from the interaction between the survey design (geographic extent, sample size, use of existing data), logistics (sampling period, sample shipping, information management, crew expertise, field training), and the suite of ecological indicators selected (site-scale sampling design, field and laboratory protocols). We use our experience with the EPA's national Wadeable Stream Assessment and its Environmental Monitoring and Assessment Program Western Pilot Study to describe the key constraints and the resulting decisions made to implement those surveys successfully. The experiences from those surveys offer perspectives and information useful for effectively implementing future surveys of similar scope or spatial extent, including advanced planning, compatible survey designs, consistent methods, indicators, and cooperative research.

Three regionalization schemes were considered: a single national predictive model (MOD1), separate predictive models for each of the 9 WSA aggregated Omernik level III ecoregions (MOD9), and 3 predictive models roughly corresponding to the western US, the Appalachian Mountains, and the Central and Coastal Plains (MOD3). The goal of the WSA was to assess stream condition at the national scale and at the scale of WSA aggregated ecoregions, so we compared the performance of the ratio of the observed number of taxa to the expected number of taxa (O/E) index estimated using different regionalization schemes at both of these spatial scales. We assessed model performance with a randomized resampling procedure, in which we set aside 10% of the reference sites, calibrated the model with the remaining sites, and applied the model to the set-aside sites. Performance statistics for the set-aside reference sites were accumulated over 10 iterations. When summarized at the national scale, mean model predictions of O/E for set-aside reference sites from the 3 different regionalization schemes were all reasonably close to 1. When summarized by the 9 aggregated ecoregions, MOD1 and MOD3 predictions of O/E differed systematically from 1 in certain aggregated ecoregions. Over all 9 ecoregions, the magnitude of these differences was significantly greater than observed with MOD9 predictions. Results from our analysis suggest that O/E values at test sites should be interpreted with respect to mean and SD of O/E of reference sites from the same region to minimize the effects of systematic biases in the predictions. RIVPACS-type predictive models also should be calibrated at a spatial scale similar to the scale at which summary statistics are reported.

Yet at nearly all such sites, natural attenuation processes occur and may contribute to site remediation. Biogeochemical processes can be particularly important in controlling the transport and fate of certain metal and metalloid contaminants, under specific environmental conditions. This paper identifies the major natural attenuation processes that have been documented at mine sites around the world and discusses how monitored natural attenuation is sometimes used in combination with active treatment technologies to achieve site-specific remediation objectives.

We describe an approach to developing MMIs of ecological condition that is applicable to a variety of biological assemblage types and to spatially extensive (regional, national) aquatic resource surveys. The process involves testing the performance characteristics of candidate metrics in several categories that correspond to key dimensions of biotic condition. The performance characteristics include: information content (range), reproducibility, calibration for natural gradients, responsiveness to stressor gradients, and independence from other metrics. The best-performing metric from each category is included in the final MMI. The consistency of the process enables development of separate MMIs in different regions that can be combined in a national assessment and that are more comparable across regions and taxonomic groups than a set of independently developed MMIs would be. We provide an example of the process applied to macroinvertebrate data from the US Environmental Protection Agency's Wadeable Streams Assessment (WSA) from 3045 sites (of which 1390 were WSA probability sites). The MMIs developed for the WSA demonstrate the feasibility of conducting bioassessments at continental scales and provide a basis for interpreting existing MMIs from regional- and national-level perspectives.

We analyzed the distribution of 12 invasive taxa (common burdock [Arctium minus], giant reed [Arundo donax], cheatgrass [Bromus tectorum], musk thistle [Carduus nutans], Canada thistle [Cirsium arvense], teasel [Dipsacus fullonum], Russian olive [Elaeagnus angustifolia], leafy spurge [Euphorbia esula], English ivy [Hedera helix], reed canarygrass [Phalaris arundinacea], Himalayan blackberry [Rubus armeniacus], and saltcedar [Tamarix spp.]) to characterize a portion of that stressor. Observations from 961 probability survey reaches and 355 additional reaches distributed across 12 western US states provided a statistically defensible foundation for trend monitoring, risk assessments, or economic evaluation of these 12 taxa over a large area. We estimate that .1 of these taxa are present in riparian areas on 47 c 3.6% of the perennial stream length in the western US. One or more of these taxa were present in >1/3 of the reaches identified as least-disturbed (reaches that define reference condition and are used to quantify instream biotic integrity). Association between target invasive presence and instream biotic integrity varied, particularly as a function of ecoregion. Relationships were often statistically significant in the Mountain climatic region, sometimes significant in the Xeric climatic region, and never significant in the Plains climatic region. Regional variations in associations and confounding relationships between multiple factors suggest that multiple variables should be examined to explain or predict the presence of invasive species or their associations. Our survey illustrates strengths and limitations of collecting information on a limited number of invasive plants in riparian vegetation as part of general probability surveys of aquatic ecosystems. Our survey of only 12 somewhat arbitrarily selected invasive plants provided much information for a limited cost. We recommend including similar efforts in future surveys.

The Superettes Program was a multiyear, $27 million air quality monitoring program consisting of eight regional air quality projects located throughout the United States, each with differing atmospheric pollution conditions resulting from variations in source emissions and meteorology. The overall goal of the program was to elucidate source-receptor relationships and atmospheric processes leading to PM accumulation on urban and regional scales; thus providing the scientific underpinning for modeling and data analysis efforts to support State Implementation Plans and more effective risk management approaches for PM. The program had three main objectives: (1) conduct methods development and evaluation, (2) characterize ambient PM, and (3) support health effects and exposure research. This paper provides a synthesis of key scientific findings from the Supersites Program and related studies. EPA developed 16 science/policy-relevant questions in conjunction with state and other federal agencies, Regional Planning Organizations, and the private sector. These questions were addressed to the extent possible, even given the vast amount of new information available from the Supersites Program, in a series of papers published as a special issue of the Journal of Air & Waste Management Association (February 2008). This synthesis also includes discussions of: (1) initial Supersites Program support for air quality management efforts in specific locations throughout the United States; (2) selected policy-relevant insights, based on atmospheric sciences findings, useful to air quality managers and decision makers planning emissions management strategies to address current and future PM National Ambient Air Quality Standards (NAAQS) and network planning and implementation; (3) selected health-relevant insights interpreted from atmospheric sciences findings in light of future directions for health and exposure scientists planning studies of the effects of PM on human health; and (4) selected knowledge gaps to guide future research. Finally, given the scope and depth of research and findings from the Supersites Program, this paper provides a reference source so readers can glean a general understanding of the overall research conducted and its policy-relevant insights. Supporting details for the results presented are available through the cited references. An annotated table of contents allows readers to easily find specific subject matter within the text.

We play a major role in the workings of our environment and Earth's fundamental natural processes, transforming and shaping them on a global scale, with consequences today and long into the future. Web sites allow anyone with a computer and an Internet connection to observe these changes (University of Wisconsin-Madison 2005). The implication is not only that human interaction with the natural world must be better understood, but also that humans must assume a conscious and deliberate role in its management. Conservation becomes more than just correcting past mistakes and protecting resources that we value but adapting to new circumstances in a dynamic environment.

Testosterone, along with its metabolite dihydrotestosterone, is critical for the differentiation of the fetal male reproductive tract from an indifferent state, for the development of male traits during puberty, and for the maintenance of reproductive function in mature animals. The androgen signaling pathway is highly conserved in the reproductive system of all vertebrates from fish to humans; therefore, environmental chemicals have the potential to induce adverse effects in any vertebrate species. There are synthetic androgens present in the environment, and several pesticides and toxic substances display antiandrogenic activity. For example, exposure to mixtures of antiandrogens during sexual differentiation results in cumulative adverse effects in male rat offspring. Continued characterization of the role of androgens in reproductive and other systems is warranted to enable better understanding of the potential adverse effects of chemical disruption of androgen signaling.

Objectives: We reviewed regulatory actions published by U.S. Environmental Protection Agency (EPA) in the Federal Register from April 1998 through December 2006 to evaluate applicability of EO 13045 to U.S. EPA actions and consideration of children's health issues in U.S. EPA rulemakings. Discussion: Although virtually all actions discussed EO 13045, fewer than two regulations per year, on average, were subject to the EO requirement to evaluate children's environmental health risks. Nonetheless, U.S. EPA considered children's environmental health in all actions addressing health or safety risks that may disproportionately affect children. Conclusion: The EO does not apply to a broad enough set of regulatory actions to ensure protection of children's health and safety risks, largely because of the small number of rules that are economically significant. However, given the large number of regulations that consider children's health issues despite not being subject to the EO, other statutory requirements and agency policies reach a larger set of regulations to ensure protection of children's environmental health.

Assessments of the ecological risks of chemical exposures to listed species often rely on the use of surrogate species, safety factors, and species sensitivity distributions (SSDs) of chemical toxicity; however, the protectiveness of these approaches can be uncertain. We comprehensively evaluated the protectiveness of SSD first and fifth percentile hazard concentrations (HC1, HC5) relative to the application of safety factors using 68 SSDs generated from 1,482 acute (lethal concentration of 50%, or LC50) toxicity records for 291 species, including 24 endangered species (20 fish, four mussels). The SSD HC5s and HC1s were lower than 97 and 99.5% of all endangered species mean acute LC50s, respectively. The HC5s were significantly less than the concentrations derived from applying safety factors of 5 and 10 to rainbow trout (Oncorhynchus mykiss) toxicity data, and the HC1s were generally lower than the concentrations derived from a safety factor of 100 applied to rainbow trout toxicity values. Comparison of relative sensitivity (SSD percentiles) of broad taxonomic groups showed that crustaceans were generally the most sensitive taxa and taxa sensitivity was related to chemical mechanism of action. Comparison of relative sensitivity of narrow fish taxonomic groups showed that standard test fish species were generally less sensitive than salmonids and listed fish. We recommend the use of SSDs as a distribution-based risk assessment approach that is generally protective of listed species.

To resolve the situation, Federal Highway Administration entered into a Settlement Agreement with Nevada DOT and the Sierra Club, wherein the Administration agreed to undertake a research effort to characterize the impact and behavior of particulate matter with aerodynamic diameter less than 2.5 mu m and mobile source air toxics near highways. The US Federal Highway Administration and US Environmental Protection Agency determined that it would be in the best interest of both organizations to implement this project in a collaborative manner, allowing a more effective utilization of staffing and resources. One of the first steps of the project implementation has been the selection of a suitable ambient air monitoring site in or around Las Vegas, Nevada. This article presents the multi-criteria analytical steps taken to select the near road monitoring sites to provide air quality data needed to support environmental decision-making in this project.

The release and partitioning behavior of sediment-bound heavy metals is not well understood during resuspension events. In this study, the release of Cd, Cu, Hg, Ni, Pb and Zn from sediments during resuspension was evaluated using reference sediments with known physical and chemical properties. Sediment treatments with varying quantities of acid volatile sulfide (AVS), total organic carbon (TOC), and different grain size distributions were resuspended under controlled conditions to evaluate their respective effects on dissolved metal concentrations. AVS had the greatest effect on limiting release of dissolved metals, followed by grain size and TOC. Predictions of dissolved concentrations of Cd, Ni, Pb and Zn were developed based on the formulated sediment sub(m) sub(e) sub(t) sub(a) sub(l)/AVS ratios with sub(m) sub(e) sub(t) sub(a) sub(l) being the total sediment metal concentration. Predicted values were compared to measured dissolved metal concentrations in contaminated field sediments resuspended under identical operating conditions. Metal concentrations released from the field sediments were low overall, in most cases lower than predicted values, reflecting the importance of other binding phases.

In this study two internal, positive controls were developed to control for both amplification and cell lysis in assays measuring abundance of vegetative Gram-positive bacteria. Methods and Results:Controls were constructed using Streptococcus gordonii DL-1, a naturally transformable, Gram-positive bacterium. Unique target sequences were provided by chromosomal insertion of a genetically modified, green fluorescent protein gene fragment. Results suggest that their use for control of lysis and amplification may be of significant value. Conclusions:The use of these controls and the establishment of data quality objectives to determine the tolerable level of decision error should ensure that environmental decisions based on QPCR data are technically and scientifically sound. Significance and Impact of the Study:QPCR measurements related to cell abundance may vary between samples as thick-walled Gram-positive bacteria are inherently difficult to lyse and substances present in recreational waters may inhibit amplification. As QPCR methods are considered for beach monitoring, it is essential to demonstrate that the data obtained accurately reflects the abundance of the bacterial indicator.

AN - 19660358; 8783143 AB - Despite significant concern about drought impacts in Australia, there have been no broad-scale studies of drought effects on river health. A severe and prolonged drought has been acting on many streams in south eastern Australia over the past decade. EPA Victoria has undertaken rapid bioassessment (RBA) of over 250 stream reference sites since 1990, providing an opportunity for a before-after-control-impact investigation of drought related changes to macroinvertebrate indices and water quality. This study uses data from 1990 to 2004 to critically evaluate the effectiveness of using RBA methods and indices, which were designed for assessment of human impacts, for monitoring streams during drought.Reference stream sites across Victoria (those with minimal anthropogenic disturbances and repeatedly sampled) were classified as being 'in drought' or 'not in drought' using the Bureau of Meteorology's rainfall deficiency definition. Four biological indices (SIGNAL, EPT, Family Richness and AUSRIVAS) were calculated for combined autumn and spring samples for edge and riffle habitats for the selected sites.General linear models and paired t-tests were used to detect drought related changes to index and water quality values at state-wide and bioregional scales. Changes in taxa constancy were examined to determine which taxa were sensitive to or benefited from drought conditions. Frequency of site failure against biological objectives specified in the State Environment Protection Policy (Waters of Victoria) (herein termed 'SEPP WoV') before and during drought was also examined to detect changes in a management context.Few significant changes in index values were detected for riffle habitat samples. Rates of failure against biological objectives were similar before and during drought for riffle samples. In contrast, edge habitat AUSRIVAS and SIGNAL scores were significantly reduced at the state-wide scale and most indices showed significant declines in the lower altitude forests, and foothills and coastal plains bioregions.Generally, more pollution tolerant, lentic taxa replaced sensitive and flow-requiring taxa in edge samples during drought. In contrast, there were few reductions in the taxa of riffle samples during drought. However, many pool preferring, but pollution sensitive taxa occurred more frequently in riffle areas. Hence, the riffle community began to resemble that of pools and edges. This was attributed to decreased flow and increased 'lentic' habitat opportunities in riffles.Detection of a drought effect was confined to the edge habitat and site failure could be assigned to drought and anthropogenic impacts, in conjunction or alone. The riffle sampling protocol was resistant to detection of drought effects as samples were only taken when sufficient water was present within this habitat. Therefore, biological changes at sites not meeting policy objectives for riffle habitats can be attributed to anthropogenic rather than drought impacts.

ER - TY - JOUR T1 - Contributions of diesel truck emissions to indoor elemental carbon concentrations in homes in proximity to Ambassador Bridge AN - 19590490; 8801017 AB - Ambassador Bridge, connecting Detroit, Michigan and Windsor, Ontario, is the busiest international commercial vehicle crossing in North America, with a large percentage of heavy duty diesel trucks. This study seeks to examine the contribution of diesel truck traffic across Ambassador Bridge to indoor exposure patterns of elemental carbon (EC), a common surrogate for diesel exhaust particles, in homes in close proximity to the bridge. We also aim to understand the relative importance of home ventilation characteristics and wind speed. Measurements were collected as part of the Detroit Exposure and Aerosol Research Study (DEARS). Residential indoor and outdoor EC measurements were collected over five consecutive 24 h periods in both the summer and winter at 16 homes in close proximity to Ambassador Bridge. Ambient concentrations and meteorological data were collected at a central-site monitor, and home air exchange rates were estimated using a perfluorocarbon tracer. The contributions of ambient concentrations and Ambassador Bridge, and potential effect modification by wind speed and home ventilation status were quantified with regression analyses. Both ambient concentrations and the percentage of time a home was downwind from the bridge were associated with an increase in indoor concentrations. Ambient concentrations significantly contributed to indoor concentrations regardless of wind speed category but were a greater influence in home experiencing calm winds. The effect of the percent of time downwind variable on indoor levels was only significant in homes where the ventilation status was high. The distance a home was from the bridge tollbooth complex was not significantly associated with indoor concentrations. We conclude that diesel traffic emissions related to Ambassador Bridge may have an impact on indoor EC exposures. Given that people spend the majority of their time indoors, it is important to evaluate the impact of traffic-related pollution in the home environment.

Method accuracy ranged between 86 and 125% with limits of quantitation between 0.2 and 10ng/g wet weight. Intra- and inter-batch precision was generally +/-20%. Perfluorooctane sulfonate (PFOS) was the predominant compound identified in these samples, contributing over 80% of total PFC composition in the fish from these rivers, with median PFOS concentrations of 24.4, 31.8, and 53.9ng/g wet wt in the Missouri, Ohio, and Mississippi Rivers, respectively. Median PFOS levels were significantly (p=0.01) elevated in piscivorous fish (88.0ng/g) when compared with non-piscivorous fish (15.9ng/g). The 10 samples with PFOS concentrations above 200ng/g were broadly scattered across all three rivers, providing evidence of the widespread presence of this compound in these US waterways.

To overcome these difficulties, this study investigated a novel procedure for performing simultaneous calibration of multiple models (SCMM). By combining a hybrid global-plus-polishing search heuristic with a biased-but-random adaptive model evaluation step, the new SCMM method calibrates multiple models via efficient exploration of the multi-model calibration space. Central algorithm components are an adaptive assignment of model preference weights, mapping functions relating the uncertain parameters of the alternative models, and a shuffling step that efficiently exploits pseudo-optimal configurations of the alternative models. The SCMM approach was applied to two nitrate contamination problems involving batch reactions and one-dimensional reactive transport. For the chosen problems, the new method produced improved model fits (i.e. up to 35% reduction in objective function) at significantly reduced computational expense (i.e. 40-90% reduction in model evaluations), relative to previously established benchmarks. Although the method was effective for the test cases, SCMM relies on a relatively ad-hoc approach to assigning intermediate preference weights and parameter mapping functions. Despite these limitations, the results of the numerical experiments are empirically promising and the reasoning and structure of the approach provide a strong foundation for further development.

Here we describe patterns of genetic diversity across both the native and introduced ranges of C. maenas and its sister species, C. aestuarii, including all known non-native populations. The global data set includes sequences from the mitochondrial cytochrome c oxidase subunit I gene, as well as multilocus genotype data from nine polymorphic nuclear microsatellite loci. Combined phylogeographic and population genetic analyses clarify the global colonization history of C. maenas, providing evidence of multiple invasions to Atlantic North America and South Africa, secondary invasions to the northeastern Pacific, Tasmania, and Argentina, and a strong likelihood of C. maenas C. aestuarii hybrids in South Africa and Japan. Successful C. maenas invasions vary broadly in the degree to which they retain genetic diversity, although populations with the least variation typically derive from secondary invasions or from introductions that occurred more than 100 years ago.

Studies using a flow reactor packed with 10% vanadia/titania (V sub(2)O sub(5)/TiO sub(2)) catalyst showed complete conversion of dimethyl sulfide (DMS) in the presence of ozone. The molar yields of partial oxidation products were only 10-20%. Small amounts of partial oxidation products, such as and dimethyl sulfone (DMSO sub(2)), dimethyl disulfide (DMDS), and dimethyl sulfoxide (DMSO), were also formed. The results of the oxidation of DMS using ozone only, ozone plus catalyst, and oxygen plus catalyst suggest that the combined use of O sub(3) with catalyst is essential for the complete destruction of DMS to CO sub(2) and SO sub(2). A Box-Behnken design was used to determine the factors that have a significant effect on the conversion and selectivity of the products. It was concluded that product selectivity is strongly influenced by temperature, gas hourly space velocity (GHSV), and ozone concentration. The catalysts were characterized using XRD, surface area measurements, and SEM techniques. Time- on-stream studies carried out in a 500 ppmv gas stream held at 150 degree C for 6 h, using 2 g of the catalyst, an ozone-to-DMS molar ratio of 0.9, and a GHSV of 37,000 h super(-1), yielded 99.9% conversion of DMS. A plausible reaction mechanism has been proposed for the oxidation of DMS based on reaction product distribution and possible intermediates formed.

A seasonal interference with the method was observed in some municipal source waters collected from reservoirs and as reported to Shaw Environmental, Inc. in the summers of 2005, 2006, and 2007. This interference, which was not confined to a single region of the nation, caused clumping of the IMS beads during the acid dissociation of the IMS procedure in Method 1623. This effect lowered method recoveries for both Cryptosporidium and Giardia; however, the effect was more pronounced for Giardia. A heat dissociation technique (Ware et al., (2003) J. Microbiol. Methods 55, 575-583) was shown to be a viable option for samples which demonstrate the clumping matrix effect and improved Giardia recoveries in partially clumped samples. The heat dissociation application holds promise for fully clumped samples and warrants further investigation.

We derive economic values for housing relating to remediating the effects of acid mine drainage using 21 years of housing sales data, and use geographic information systems to link housing market sales data with stream water quality. The results indicate being located near an acid mine drainage-impaired stream has an implicit marginal cost of $4,783 on housing. If all the streams are restored in the Cheat River Watershed, those properties located near the restoration (within a 1/4 mile) would benefit by $1.7 million.

Our efforts have been geared toward the development of granular activated carbon (GAC) impregnated with reactive iron/palladium (Fe/Pd) bimetallic nanoparticles (reactive activated carbon (RAC)). In this study, we elucidate the mechanistic aspects of the hybrid RAC system dechlorinating 2-chlorobiphenyl (2-ClBP) in the aqueous phase. The following reactions occurred in parallel or consecutively: (i) 2-ClBP is promptly and completely sequestrated to RAC phase, (ii) the adsorbed 2-ClBP is almost simultaneously dechlorinated by Fe/Pd particles to form a reaction product biphenyl (BP), and (iii) the BP formed is instantly and strongly adsorbed to RAC. The 2-ClBP adsorption and dechlorination rate constants were estimated through simple first-order reaction kinetic models with an assumption for unextractable portion of carbon in RAC. The extent of 2-ClBP accumulation and BP formation in RAC phase could be well explained by the kinetic model and adsorption was found to be the rate limiting step for overall reaction. On the basis of our observations, a new strategy and concept of 'reactive' cap/barrier composed of RAC was proposed as a new environmental risk management option for PCBs-contaminated sites.

To assess the effect of 'aging' and surface modification on its potential neurotoxicity, cultured rodent microglia (BV2) and neurons (N27) were exposed to fresh nZVI, 'aged' (>11 months) nZVI, magnetite, and polyaspartate surface-modified (SM) nZVI. Increases in various measures of oxidative stress indicated that BV2 microglia responded to these materials in the following rank order: nZVI > 'aged' nZVI > magnetite = SM nZVI. Fresh nZVI produced morphological evidence of mitochondrial swelling and apoptosis. In N27 neurons, ATP levels were reduced in the following rank order: nZVI > SM-nZVI >'aged' nZVI = magnetite. Ultrastructurally, nZVI produced a perinuclear floccular material and cytoplasmic granularity. Both SM-nZVI produced intracellular deposits of nanosize particles in the N27. The physicochemical properties of each material, measured under exposure conditions, indicated that all had electronegative zeta potentials. The iron content of nZVI (35%) and SM-nZVI (25%) indicated high 'redox' activity while that of 'aged' and magnetite was neglibile. Sedimentation and agglomeration occurred in the following rank order: nZV > 'aged' nZVI > magnetite SM-nZVI. Correlating these properties with toxicity indicated that partial or complete oxidation of nZVI reduced its 'redox' activity, agglomeration, sedimentation rate, and toxicity to mammalian cells. Surface modification decreased nZVI toxicity by reducing sedimentation which limited particle exposure to the cells.

PCBs (polychlorinated biphenyls) were one of the targeted pollutants studied in the project. As one of the components in the overall LMMBP modeling framework, the LM2-Toxic model was developed to simulate fate and transport of PCB congeners in the Lake Michigan ecosystem. The purpose of the LM2-Toxic model was to address the relationship between sources of PCBs and their resultant concentrations in water and sediments of Lake Michigan and identify key environmental processes that strongly influence mass fluxes of the targeted pollutants in the lake. The model is sophisticated and is an extension of the widely used WASP model in terms of describing physical and biochemical processes within an aquatic system. Three organic carbon sorbents (biotic carbon, particulate detrital carbon, and dissolved organic carbon) and 54 PCB congeners were simulated as individual state variables. Using 1994 and 1995 project-generated field data, the organic carbon solids dynamics were calibrated first. This was followed by the calibration of PCB dynamics. The model construct and calibration results demonstrated significant improvements over historical mass balance models applied to the Lake Michigan ecosystem. The model results indicate that air-water exchange and interaction between the water column and sediment are the most important processes for PCBs in Lake Michigan.

AN - 69943371; 19017407 AB - Pyrethroids are neurotoxic pesticides that interact with membrane bound ion channels in neurons and disrupt nerve function. The purpose of this study was to characterize and explore changes in gene expression that occur in the rat frontal cortex, an area of CNS affected by pyrethroids, following an acute low-dose exposure. Rats were acutely exposed to either deltamethrin (0.3 - 3 mg/kg) or permethrin (1 - 100 mg/kg) followed by collection of cortical tissue at 6 hours. The doses used range from those that cause minimal signs of intoxication at the behavioral level to doses well below apparent no effect levels in the whole animal. A statistical framework based on parallel linear (SAM) and isotonic regression (PIR) methods identified 95 and 53 probe sets as dose-responsive. The PIR analysis was most sensitive for detecting transcripts with changes in expression at the NOAEL dose. A sub-set of genes (Camk1g, Ddc, Gpd3, c-fos and Egr1) was then confirmed by qRT-PCR and examined in a time course study. Changes in mRNA levels were typically less than 3-fold in magnitude across all components of the study. The responses observed are consistent with pyrethroids producing increased neuronal excitation in the cortex following a low-dose in vivo exposure. In addition, Significance Analysis of Function and Expression (SAFE) identified significantly enriched gene categories common for both pyrethroids, including some relating to branching morphogenesis. Exposure of primary cortical cell cultures to both compounds resulted in an increase (approximately 25%) in the number of neurite branch points, supporting the results of the SAFE analysis. In the present study, pyrethroids induced changes in gene expression in the frontal cortex near the threshold for decreases in ambulatory motor activity in vivo. The penalized regression methods performed similarly in detecting dose-dependent changes in gene transcription. Finally, SAFE analysis of gene expression data identified branching morphogenesis as a biological process sensitive to pyrethroids and subsequent in vitro experiments confirmed this predicted effect. The novel findings regarding pyrethroid effects on branching morphogenesis indicate these compounds may act as developmental neurotoxicants that affect normal neuronal morphology.

Occurrence and mammalian cell toxicity of iodinated disinfection byproducts in drinking water. AN - 69874848; 19068814 AB - An occurrence study was conducted to measure five iodo-acids (iodoacetic acid, bromoiodoacetic acid, (Z)-3-bromo-3-iodo-propenoic acid, (E)-3-bromo-3-iodo-propenoic acid, and (E)-2-iodo-3-methylbutenedioic acid) and two iodo-trihalomethanes (iodo-THMs), (dichloroiodomethane and bromochloroiodomethane) in chloraminated and chlorinated drinking waters from 23 cities in the United States and Canada. Since iodoacetic acid was previouslyfound to be genotoxic in mammalian cells, the iodo-acids and iodo-THMs were analyzed for toxicity. A gas chromatography (GC)/negative chemical ionization-mass spectrometry (MS) method was developed to measure the iodo-acids; iodo-THMs were measured using GC/high resolution electron ionization-MS with isotope dilution. The iodo-acids and iodo-THMs were found in waters from most plants, at maximum levels of 1.7 microg/L (iodoacetic acid), 1.4 microg/L (bromoiodoacetic acid), 0.50 microg/L ((Z)-3-bromo-3-iodopropenoic acid), 0.28 microg/L ((E)-3-bromo-3-iodopropenoic acid), 0.58 microg/L ((E)-2-iodo-3-methylbutenedioic acid), 10.2 microg/L (bromochloroiodomethane), and 7.9 microg/L (dichloroiodomethane). Iodo-acids and iodo-THMs were highest at plants with short free chlorine contact times ( 45 min). Iodide levels in source waters ranged from 0.4 to 104.2 microg/L (when detected), but there was not a consistent correlation between bromide and iodide. The rank order for mammalian cell chronic cytotoxicity of the compounds measured in this study, plus other iodinated compounds, was iodoacetic acid > (E)-3-bromo-2-iodopropenoic acid > iodoform > (E)-3-bromo-3-iodo-propenoic acid > (Z)-3-bromo-3-iodo-propenoic acid > diiodoacetic acid > bromoiodoacetic acid > (E)-2-iodo-3-methylbutenedioic acid > bromodiiodomethane > dibromoiodomethane > bromochloroiodomethane approximately chlorodiiodomethane > dichloroiodomethane. With the exception of iodoform, the iodo-THMs were much less cytotoxic than the iodo-acids. Of the 13 compounds analyzed, 7 were genotoxic; their rank order was iodoacetic acid >> diiodoacetic acid > chlorodiiodomethane > bromoiodoacetic acid > E-2-iodo-3-methylbutenedioic acid > (E)-3-bromo-3-iodo-propenoic acid > (E)-3-bromo-2-iodopropenoic acid. In general, compounds that contain an iodo-group have enhanced mammalian cell cytotoxicity and genotoxicity as compared to their brominated and chlorinated analogues.

AN - 69803438; 18671995 AB - Risk assessment for human health effects often depends on evaluation of toxicological literature from a variety of sources. Risk assessors have limited resources for obtaining raw data, performing follow-on analyses or initiating new studies. These constraints must be balanced against a need to improve scientific credibility through improved statistical and analytical methods that optimize the use of available information. Computerized databases are used in toxicological risk assessment both for storing data and performing predictive analyses. Many systems provide primarily either bibliographic information or summary factual data from toxicological studies; few provide adequate information to allow application of dose-response models. The Exposure-Response database (ERDB) described here fills this gap by allowing entry of sufficiently detailed information on experimental design and results for each study, while limiting data entry to the most relevant. ERDB was designed to contain information from the open literature to support dose-response assessment and allow a high level of automation in performance of various types of dose-response analyses. Specifically, ERDB supports emerging analytical approaches for dose-response assessment, while accommodating the diverse nature of published literature. Exposure and response data are accessible in a relational multi-table design, with closely controlled standard fields for recording values and free-text fields to describe unique aspects of the study. Additional comparative analyses are made possible through summary tables and graphic representations of the data contained within ERDB.

AN - 69803314; 18329062 AB - In human health risk assessment, information from epidemiologic studies is typically utilized in the hazard identification step of the risk assessment paradigm. However, in the assessment of many chemicals by the Integrated Risk Information System (IRIS), epidemiologic data, both observational and experimental, have also been used in the derivation of toxicological risk estimates (i.e., reference doses [RfD], reference concentrations [RfC], oral cancer slope factors [CSF] and inhalation unit risks [IUR]). Of the 545 health assessments posted on the IRIS database as of June 2007, 44 assessments derived non-cancer or cancer risk estimates based on human data. RfD and RfC calculations were based on a spectrum of endpoints from changes in enzyme activity to specific neurological or dermal effects. There are 12 assessments with IURs based on human data, two assessments that extrapolated human inhalation data to derive CSFs and one that used human data to directly derive a CSF. Lung or respiratory cancer is the most common endpoint for cancer assessments based on human data. To date, only one chemical, benzene, has utilized human data for derivation of all three quantitative risk estimates (i.e., RfC, RfD, and dose-response modeling for cancer assessment). Through examples from the IRIS database, this paper will demonstrate how epidemiologic data have been used in IRIS assessments for both adding to the body of evidence in the hazard identification process and in the quantification of risk estimates in the dose-response component of the risk assessment paradigm.

AN - 69802956; 18589469 AB - Humans are exposed daily to multiple chemicals, including incidental exposures to complex chemical mixtures released into the environment and to combinations of chemicals that already co-exist in the environment because of previous releases from various sources. Exposures to chemical mixtures can occur through multiple pathways and across multiple routes. In this paper, we propose an iterative approach for assessing exposures to environmental chemical mixtures; it is similar to single-chemical approaches. Our approach encompasses two elements of the Risk Assessment Paradigm: Problem Formulation and Exposure Assessment. Multiple phases of the assessment occur in each element of the paradigm. During Problem Formulation, analysts identify and characterize the source(s) of the chemical mixture, ensure that dose-response and exposure assessment measures are concordant, and develop a preliminary evaluation of the mixture's fate. During Exposure Assessment, analysts evaluate the fate of the chemicals comprising the mixture using appropriate models and measurement data, characterize the exposure scenario, and estimate human exposure to the mixture. We also describe the utility of grouping the chemicals to be analyzed based on both physical-chemical properties and an understanding of environmental fate. In the article, we also highlight the need for understanding of changes in the mixture composition in the environment due to differential transport, differential degradation, and differential partitioning to other media. The Results section describes the application of the method to various chemical mixtures, highlighting issues associated with assessing exposures to chemical mixtures in the environment.

AN - 69801183; 18692516 AB - The toxicity value database of the United States Environmental Protection Agency's (EPA) National Homeland Security Research Center has been in development since 2004. The toxicity value database includes a compilation of agent property, toxicity, dose-response, and health effects data for 96 agents: 84 chemical and radiological agents and 12 biotoxins. The database is populated with multiple toxicity benchmark values and agent property information from secondary sources, with web links to the secondary sources, where available. A selected set of primary literature citations and associated dose-response data are also included. The toxicity value database offers a powerful means to quickly and efficiently gather pertinent toxicity and dose-response data for a number of agents that are of concern to the nation's security. This database, in conjunction with other tools, will play an important role in understanding human health risks, and will provide a means for risk assessors and managers to make quick and informed decisions on the potential health risks and determine appropriate responses (e.g., cleanup) to agent release. A final, stand alone MS ACESSS working version of the toxicity value database was completed in November, 2007.

AN - 69800416; 18671996 AB - The Air Toxics Health Effects Database (ATHED) is currently used by the EPA's Office of Air Quality Planning and Standards (OAQPS) to support risk assessments for the Residual Risk Program. An assessment of the residual risk is required to be performed at a specified time (typically 8 years) following the promulgation of a technology-based Maximum Achievable Control Technologies (MACT) standard. The goal of the Residual Risk Program is to assure that the risk that remains after MACT standards are implemented (i.e., the "residual risk") is acceptable, and if not, to propose additional regulations to mitigate those risks. ATHED maintains all available reference values for each chemical as separate data records, and includes values for all exposure durations (acute, short-term, subchronic and chronic). These values are used as benchmarks to determine acceptable exposure levels to the hazardous air pollutants (HAPs) listed in Section 112 of the Clean Air Act. ATHED also provides useful background information on the uncertainty and/or modifying factors that were applied in the derivation of each reference value, as well as the point of departure and the critical study/studies. To facilitate comparisons across durations for a specific chemical, ATHED data can be graphically presented.

AN - 69800313; 18547599 AB - There is increasingly intense scientific and clinical interest in oxidative stress and the many parameters used to quantify the degree of oxidative stress. However, there remain many analytical limitations to currently available assays for oxidative stress markers. Recent improvements in software, hardware, and instrumentation design have made liquid chromatography and tandem mass spectroscopy (LC-MS/MS) methods optimal choices for the determination of many oxidative stress markers. In particular, LC-MS/MS often provides the advantages of higher specificity, higher sensitivity, and the capacity to determine multiple analytes (e.g. 4-11 oxidative stress markers per LC run) when compared to other available methods, such as gas chromatography-MS, immunoassays, spectrophotometric or fluorometric assays. LC-MS/MS methods are also compatible with cleanup and sample preparation methods including prior solid phase extraction or automated two dimensional LC/LC chromatography followed by MS/MS. LC-MS/MS provides three analytical filtering functions: (1) the LC column provides initial separation as each analyte elutes from the column. (2) The first MS dimension isolates ions of a particular mass-to-charge (m/z) ratio. (3) The selected precursor ion is fragmented into product ions that provide structural information about the precursor ion. Quantitation is achieved based on the abundances of the product ions. The sensitivity limits for LC-MS/MS usually lie within the range of fg-pg of analyte per LC on-column injection. In this article, the present capabilities of LC-MS/MS are briefly presented and some specific examples of the strengths of these LC-MS/MS assays are discussed. The selected examples include methods for isoprostanes, oxidized proteins and amino acids, and DNA biomarkers of oxidative stress.

AN - 69769042; 18926777 AB - In an effort to optimize reverse-phase liquid chromatography (RPLC) for proteomics, we studied the impact of composition of the sample injection solution on protein on-column selection and retention. All the proteins studied were retained on-column when injections were made in 50% formic acid, 0.1% TFA or 8.3M urea. When formic acid was increased to 80%, the superoxide dismutase standard (MW 26,159) and 58 mouse microsomal proteins that possessed low-range molecular weights, high pIs or basic amino acid clusters were non-retained, resulting in retention selectivity during sample injection. Introducing to the 80% formic acid injection solution an organic solvent such as acetonitrile or acetonitrile-DMSO induced further retention selectivity, and increasing levels of organic solvents reduced on-column retention. The proteome was split into the proteins that were retained on-column which eluted at higher retention times (RTs), vs the proteins that collected in the injection flow-through which normally eluted at lower RTs. This protein selectivity was confirmed after fraction collection, 1D-GE and nano-LC-MS/MS. The significance of this procedure is that it can be exploited for fast extraction of small basic proteins from the bulk of the proteome and for on-column enrichment of hydrophobic proteins.

Quantitative risk assessment relies upon having detailed exposure-response data, such as number of animals and incidence by exposure group in dichotomous measures and values by individual animal for continuous measures; this level of detail is often not reported in peer-reviewed studies. Additionally, biologically-based models (e.g., PBPK) are useful in risk assessment but require knowledge or collection of parameters as inputs (both chemical-specific and more general physiological parameters), and this information is not always readily available. Structure activity relationship information is also being called upon to help fill in knowledge gaps about specific chemicals where data from related chemicals may be available. Some existing data sources have been developed by various agencies for specific applications, such as those mentioned, and advantage should be taken of those existing resources; however, a great deal more is possible. The purpose of this workshop was to gather together many of the stakeholders using and developing shared toxicological information, determine the potential for greater collaboration, and determine the best course to facilitate the further development of joint information resources. A number of recommendations (development of a consensus toxicological review format, standardization of terminology and data sharing formats, and agreement on primary data elements) and topics for additional discussion were the major products of this workshop.

Lewis Military Reservation, Washington. Passive Flux Meters (PFM) and a variation of the Integral Pumping Test (IPT) were used to measure fluxes in ten wells installed along a transect down-gradient of the trichloroethylene (TCE) source zone, and perpendicular to the mean groundwater flow direction. At both sites, groundwater and contaminant fluxes were measured before and after the source-zone treatment. The measured contaminant fluxes (J; ML super(-) super(2)T super(-) super(1)) were integrated across the well transect to estimate contaminant mass discharge (M sub(D); MT super(-) super(1)) from the source zone. Estimated M sub(D) before source treatment, based on both PFM and IPT methods, were ~76 g/day for TCE at the Hill AFB site; and ~640 g/day for TCE, and ~206 g/day for cis-dichloroethylene (DCE) at the Ft. Lewis site. TCE flux measurements made 1 year after source treatment at the Hill AFB site decreased to one fourth g/day. On the other hand, increased fluxes of DCE, a degradation byproduct of TCE, in tests subsequent to remediation at the Hill AFB site suggest enhanced microbial degradation after surfactant flooding. At the Ft. Lewis site, TCE mass discharge rates subsequent to remediation decreased to reversible reaction g/day for TCE and reversible reaction g/day for DCE arrow right .8 years after remediation. At both field sites, PFM and IPT approaches provided comparable results for contaminant mass discharge rates, and show significant reductions (>90%) in TCE mass discharge as a result of DNAPL mass depletion from the source zone.

G., and Brown, C. A. 2008. Use of probability-based sampling of water-quality indicators in supporting development of quality criteria. - ICES Journal of Marine Science, 65: 1421-1427.Intensive, site-based data are typically used to establish protective water-quality criteria, but may only exist for few systems in a region. We examine whether or not water-quality indicator data collected from large-scale, probability-based assessments can support the development of regional quality criteria. Because such indicators may be subject to high natural variation over short time-scales, a key question is whether survey values will be sufficiently similar to site-based sampling to merit use in extrapolating quality criteria spatially. Median values for dissolved inorganic nitrogen, phosphorus, and Chl a for dry-season data collected within Yaquina Bay (OR, USA) over a 7-year period were compared with dry-season datasets collected from two studies comprising 6 and 14 Oregon estuaries, respectively. A second, reduced dataset (August-September only) was compared with data from 38 estuaries within the same ecoregion. All comparisons were made for marine and riverine salinity zones. Medians for Yaquina Bay were higher than those from the comparison surveys. Stochastic variation of coastal upwelling during sampling appears to cause the contrasts. Further work is required to define upwelling-based adjustments for regional, probability-based survey data before they can be used in regulatory applications. However, even without adjustment, these data may help in determining the appropriate regional context for quality criteria.

AN - 69740631; 18573814 AB - Dibenzo[a,l]pyrene (DB[a,l]P) and benzo[a]pyrene (B[a]P) are carcinogenic polycyclic aromatic hydrocarbons (PAHs) that are each capable of forming a variety of covalent adducts with DNA. Some of the DNA adducts formed by these PAHs have been demonstrated to spontaneously depurinate, producing apurinic (AP) sites. The significance of the formation of AP sites as a key event in the production of mutations and tumours by PAHs has been a subject of ongoing investigations. Because cells have efficient and accurate mechanisms for repairing background levels of AP sites, the contribution of PAH-induced AP site mutagenesis is expected to be maximal in conditions where those induced AP sites are produced in significant excess of the endogenous AP sites. In this study, we investigated the effect of two dosing regimens on the mutagenicity of DB[a,l]P and B[a]P in vivo using the Big Blue(R) transgenic mouse system. We compared administration of a single highly tumorigenic dose of each PAH with a fractionated delivery of the same total dose administered over 5 days, with the expectation that PAH-induced AP sites would be produced at a greater margin above background levels in animals receiving the high single dose than in the animals receiving the fractionated doses. Treatment with DB[a,l]P yielded a 2.5-fold (single dose) to 3-fold (fractionated dose) increase in mutant frequencies relative to controls. Both single-dose and fractionated dose treatment regimens with B[a]P produced about a 15-fold increase in mutant frequencies compared to controls. The mutations induced by B[a]P and DB[a,l]P correlated with the stable covalent DNA adducts produced by each. These mutation results are consistent with the previously identified stable covalent DNA adducts being the promutagenic lesions produced by these two PAHs and do not support a major role for depurinating adducts, contributing to PAH-induced mutagenesis in mouse lung in vivo.

AN - 69722806; 18790476 AB - Urinary metabolites of pyrethroid pesticides have been used as biomarkers to estimate human exposure to the parent insecticide. It is important to establish whether these markers are present in environments or media to which humans are exposed routinely. Failure to account for the contribution of pre-existing markers to urinary concentrations could result in risk assessments that overestimate exposure. The purpose of this study was to quantify the concentrations of 13 selected pyrethroid pesticides and their degradation products in samples of indoor dust that had been collected in vacuum cleaner bags during the children's total exposure to persistent pesticides and other persistent organic pollutants (CTEPP) study of homes and day cares in North Carolina and Ohio. Sieved contents of 85 vacuum cleaner bags were analyzed, and permethrin was found in all samples. Sixty-nine samples contained at least one additional pyrethroid, but none contained more than five pyrethroids in detectable concentrations. Resmethrin, prallethrin, and fenpropathrin were not detected in any samples, while 36 contained phenothrin. The median concentration of permethrin in the samples was 1454ng/g of dust. Excluding permethrin, pyrethroid concentrations were typically less than or equal to 100ng/g of dust. The majority of degradates were present in more than half of the dust samples, usually at concentrations of less than or equal to 100ng/g of dust. For those pyrethroids with a characteristic oxydibenzene group, the cyclopropane degradates were present at higher concentrations than the corresponding benzoic acid moieties. Using urinary concentrations of these metabolites to model human exposure to the parent pyrethroids, may over-estimate risk due to the presence of pre-existing degradates in dust.

Therefore, field trials were conducted to determine if potato (Solanum tubersum L.) vegetative growth and tuber yield and quality were affected by herbicides at below recommended field rates. Potatoes were grown in fields at the Oregon State University Horticulture Farm with herbicides applied at below recommended field application rates 14 d after emergence (DAE) or at 28 DAE. Plant height was measured before and 14 d after application. Visual foliar injury was rated 14 d after application, and tuber yield and quality parameters were measured at harvest (120 DAE). Some tubers were grown in the greenhouse the following year to determine if there were carry-over effects. Potato vegetation and tuber yield quality were generally more affected by herbicides applied at 14 DAE than at 28 DAE. Tuber yield and quality parameters were more affected by lower herbicide rates than were plant height or injury. There were significant yield losses caused by low rates of sulfometuron methyl and imazapyr and, to a lesser extent, with glyphosate and cloransulam-methyl. Bromoxynil and MCPA ((4-chloro-2-methylphenoxy)acetic) acid had little effect on the plants. Vegetative responses did not accurately predict yield and quality responses of tubers; therefore, reproductive responses should be considered in phytotoxicity test protocols for pesticide registration in the USA.

AN - 69702362; 18687352 AB - Quantitative biologically-based models describing key events in the continuum from arsenic exposure to the development of adverse health effects provide a framework to integrate information obtained across diverse research areas. For example, genetic polymorphisms in arsenic metabolizing enzymes can lead to differences in target tissue dosimetry for key metabolites causative in toxic and carcinogenic response. This type of variation can be quantitatively incorporated into pharmacokinetic (PK) models and used together with population-based modeling approaches to evaluate the impact of genetic variation in methylation capacity on dose of key metabolites to target tissue. The PK model is an essential bridge to the pharmacodynamic (PD) models. A particular benefit of PD modeling for arsenic is that alternative models can be constructed for multiple proposed modes of action for arsenicals. Genomics data will prove useful for identifying the key pathways involved in particular responses and aid in determining other types of data needed for quantitative modeling. These models, when linked with PK models, can be used to better understand and explain dose- and time-response behaviors. This in turn assists in prioritizing modes of action with respect to their risk assessment relevance and future research. This type of integrated modeling approach can form the basis for a highly informative mode-of-action directed risk assessment for inorganic arsenic (iAs). This paper will address both practical and theoretical aspects of integrating PK and PD data in a modeling framework, including practical barriers to its application.

AN - 69659837; 18849687 AB - Cancer risk estimates are used in the setting of radiation protection standards by international and national organizations, and for this purpose need to be developed for low doses of radiation. The approach has involved extrapolation from cancer mortality and incidence values at higher doses to predict the low-dose estimates. Such an extrapolation has generally involved the use of the linear non-threshold (LNT) theory. Recent reports from the National Research Council (BEIR VII) and the International Commission on Radiological Protection (ICRP) have considered the appropriateness of the use of LNT for the purposes of radiation protection standard setting. The overall conclusion from both committees was that current scientific evidence remains consistent with the LNT hypothesis, while appreciating that this might not rule out the possibility that other extrapolation models might well be valid but require further evaluation and additional research to establish their validity. The dose and dose-rate effectiveness factor (DDREF) is used for adjustment in the extrapolation from high to low doses and from high to low dose rates. The BEIR VII committee proposed a new Bayesian approach for estimating DDREF and concluded that a value of 1.5 best fit the data. This is a departure from the previously used value of 2, which is still proposed by ICRP in its most recent recommendations. The current cancer risk estimation process as utilized by ICRP and BEIR VII is used here to assess the potential risks from annual whole-body computed tomography (CT) screens using information and an approach published by Brenner and Ellington. The major conclusion is that potential radiation risks need to be considered along with the pros and cons of the detection limits of the procedure and the impact of false positives.

AN - 69650994; 18653662 AB - In order to gain insight into the effects of aging on susceptibility to environmental toxins, we characterized the expression of xenobiotic metabolizing enzymes (XMEs) from the livers of male F344 and Brown Norway (BN) rats across the adult lifespan. Using full-genome Affymetrix arrays, principal component analysis showed a clear age-dependent separation between young and old animals in both rat strains. Out of 1135 or 1435 genes altered between the old and young groups in the F344 or BN rats, 7 or 3% were XMEs and included members of the phase I, II, and III classes of genes. There was a 20 or 32% overlap in the gene expression profile between the two strains for F344 or BN, respectively. Lipid, ergosterol, alcohol, and fatty acid metabolism genes were also altered with age in both strains. Some of the genes altered by age exhibited a gender-dependent expression pattern in young adult rats, suggesting an increasingly feminized pattern of gene expression with age in male rats. To examine transcriptional responses across lifespan after challenge with a xenobiotic compound, BN rats were exposed to toluene by oral gavage. Toluene exposure decreased the expression of glutathione synthetase, and dramatically increased the number of phase III genes being downregulated. The expression of CYP2B2 and glutathione-S-transferase decreased with age but increased in all age groups after toluene exposure. Decreased ability to detoxify and transport chemicals out of the body with age could result in increased susceptibility to some classes of chemicals in the aging population.

AN - 69648128; 18713766 AB - Perfluoroalkyl acids (PFAAs) are surfactants used in consumer products and persist in the environment. Some PFAAs elicit adverse effects on rodent development and survival. PFAAs can activate peroxisome proliferator-activated receptor alpha (PPARalpha) and may act via PPARalpha to produce some of their effects. This study evaluated the ability of numerous PFAAs to induce mouse and human PPARalpha activity in a transiently transfected COS-1 cell assay. COS-1 cells were transfected with either a mouse or human PPARalpha receptor-luciferase reporter plasmid. After 24 h, cells were exposed to either negative controls (water or dimethyl sulfoxide, 0.1%); positive control (WY-14643, PPARalpha agonist); perfluorooctanoic acid or perfluorononanoic acid at 0.5-100 microM; perfluorobutanoic acid, perfluorohexanoic acid, perfluorohexane sulfonate, or perfluorodecanoic acid (PFDA) at 5-100 microM; or perfluorobutane sulfonate or perfluorooctane sulfonate at 1-250 microM. After 24 h of exposure, luciferase activity from the plasmid was measured. Each PFAA activated both mouse and human PPARalpha in a concentration-dependent fashion, except PFDA with human PPARalpha. Activation of PPARalpha by PFAA carboxylates was positively correlated with carbon chain length, up to C9. PPARalpha activity was higher in response to carboxylates compared to sulfonates. Activation of mouse PPARalpha was generally higher compared to that of human PPARalpha. We conclude that, in general, (1) PFAAs of increasing carbon backbone chain lengths induce increasing activity of the mouse and human PPARalpha with a few exceptions, (2) PFAA carboxylates are stronger activators of mouse and human PPARalpha than PFAA sulfonates, and (3) in most cases, the mouse PPARalpha appears to be more sensitive to PFAAs than the human PPARalpha in this model.

In addition, environmental factors affecting the occurrence of these markers were identified. Each assay was performed using DNA extracts from water and sediment samples collected from a watershed directly impacted by cattle fecal pollution (WS1) and from a watershed impacted only through runoff (WS2). In WS1, the ruminant-specific Bacteroidales 16S rRNA gene marker CF128F was detected in 65% of the water samples, while the non-16S rRNA gene markers Bac1, Bac2, and Bac5 were found in 32 to 37% of the water samples. In contrast, all source-specific markers were detected in less than 6% of the water samples from WS2. Binary logistic regressions (BLRs) revealed that the occurrence of Bac32F and CF128F was significantly correlated with season as a temporal factor and watershed as a site factor. BLRs also indicated that the dynamics of fecal-source-tracking markers correlated with the density of a traditional fecal indicator (P < 0.001). Overall, our results suggest that a combination of 16S rRNA gene and non-16S rRNA gene markers provides a higher level of confidence for tracking unknown sources of fecal pollution in environmental samples. This study also provided practical insights for implementation of microbial source-tracking practices to determine sources of fecal pollution and the influence of environmental variables on the occurrence of source-specific markers.

Yet to date little emphasis has been placed on identifying these areas and prioritizing them for conservation. In this study I outline a three-step process to identify and prioritize local sites for conservation using waterbird abundance and diversity and an index of the risk to a site from marine development, and apply it to a series of urban coastal sites in two North Atlantic estuaries located in the northeast US. By combining waterbird abundance and species richness with the risk from marine development I generated a ranked list of sites with the highest listed sites having high bird diversity and low risk from development. From this list individual sites can be prioritized for conservation, and various protection scenarios can be evaluated and compared. For example, 7 of the top 10 ranked sites in Boston Harbor, combined with sites already protected under local, state, or federal statutes, represented over half of the total bird diversity in the Harbor. Similarly, in Narragansett Bay 6 of the top 10 sites when combined with sites already protected represent 48.8% of the Bay's bird diversity. Formally protecting these sites, all of which are at relatively low risk from marine development, could result in the conservation of considerable waterbird habitat at low economic cost (i.e., from loss of development potential). Other ranking scenarios (by bird diversity alone, or by risk from marine development) were also evaluated and compared to the combined ranking. Identification of sites with high bird diversity and low risk from development could provide important information for local land acquisition groups and planning boards when considering options for the conservation of urban coastal habitats.

This article presents estimates of daily average per capita water ingestion for women of child-bearing age and in three subgroups: pregnant, lactating, and non-pregnant/non-lactating women. Estimates of means and upper percentiles of subgroup ingestion distributions were generated using participant responses and survey weights from the United States Department of Agriculture's (USDA) 1994-96 and 1998 Continuing Survey of Food Intake by Individuals (CSFII). The ingestion estimates are empirical and not based on an assumed parametric distribution of daily average amount of water ingestion. Water occurring naturally in foods or added by manufacturers to commercial products is not included in the estimates presented. These estimates of water ingestion by women of child-bearing age are compared to those attributed to Ershow and Cantor (1989) by Burmaster (1998). These estimates, based on data collected in 1978, were used by Burmaster to characterize the distribution of daily average per capita ingestion as lognormal. The lognormal estimates of total water ingestion are generally greater than the total water ingestion estimates based on the CSFII data. Possible explanations for the differences are discussed.

Persistently inhaled CE produces endometrial cancers in female mice. The first-tumor-corrected uterine endometrial incidence (I) in B6C3F1 mice is 90%, but no significant tumors occurred in F344 rats. The endometrial cancers dispersed by 1) migrating locally to the adjacent myometrium, 2) then migrating to the bloodstream by intravasa-tion, 3) entering 17 distal organs by extravasation and adapting to the new tissue environment. Distal cancers retained sufficient endometrial cell features to be recognized at each metastatic site. CE produced one of the highest metastasis rates ever observed by NTP of 79%. Comparing CE with bromoethane (BE), a structural analogue, it was found that BE too produced rare murine endometrial cancers yielding the second highest NTP incidence rate of I = 58% with a similar high malignancy rate of 56%. Because of the historical rarity of endometrial tumors in the B6C3F1 mouse, bckh of these SAR haloethanes seem to be evoking a strong, related carcinogenic potential in B6C3F1 mice, but not in F344 rats. The question of whether humans are similar to mice or to rats is addressed here and in Gargas, et al, 2008. The powerful carcinogenesis caused by these halohydrocarbons may have been ciused by excessive and metabolically unresolved acetaldehyde (AC) which is directly generated by Cyp2E1 in the oxidative elimination of CE. With >95% AC metabolic production, as predicted from pharmacokinetic (PK) studies depending on CE exposure, AC is the main elimination intermediate. AC is a known animal carcinogen and a strongly suspected human carcinogen. Also, CE causes incipient decreases of tissue essential glutathione pools [GSH] by Phase II conjugation metabolic elimination of CE (and BE), by glutantione transferase (GST), in most organs (except brain) exposed to high circulating CE and it metabolites. In three laboratories, an excessive stress reaction of hyperkinesis was observed only during 15,000 ppm gas exposure but not when the exposure ceased or when exposure was presented at 150 ppm. Test rodents other than the female mice did not exhibit a pattern of visible stress nor did they have a carcinogenic response to CE gas. Unremitting stress has been documented to contribute a feedback to the hypothalamus which stimulates the hypothalamic-pituitary-axis (HPA), which in turn, induces the adrenal glands. Because estrus and estrogen and progesterone levels were unaltered by CE gas, the adrenal over stimulation, causing high steroid output, may be the penultimate step in this extraordinary carcinogenic response. High adrenal production of corticosteroids could adversely promote endometrial cells to cancers in mice - a mechanism that has already been observed in humans.

Since these indices are easy to calculate, they offer an advantage for large datasets over descriptors more difficult to calculate, and also for regulatory applications where time constraints may not allow extensive computations. Here, we show their utility in predicting normal boiling points of a variety of halogenated alkanes, using more diverse sets of molecules than previously published studies. The best model produced in this work had r2 = 0.97 and an absolute mean error of 9.98 K for a robust validation set.

The resulting data will be useful in the multipollutant management of ozone, nitrogen oxides, and visibility (atmospheric regional haze) in the Four Corners area, an area with growing oil/gas production and increasing coal-based power plant construction. The passive monitoring data also add new ambient ammonia concentration information for the U.S. and will be useful to scientists involved in present and future visibility modeling exercises. Three week integrated passive ammonia samples were taken at five sites in the Four Corners area and two sites in eastern Oklahoma from December, 2006 through December, 2007 (January, 2008 for two sites). Results show significantly higher regional background ammonia concentrations in eastern Oklahoma (1.8 parts per billion (ppb) arithmetic mean) compared to the Four Corners area (0.2 ppb arithmetic mean). Annual mean ammonia concentrations for all Four Corners area sites for the 2007 study ranged from 0.2 ppb to 1.5 ppb. Peak ambient ammonia concentrations occurred in the spring and summer in both areas. The passive samplers deployed at the Stilwell, Oklahoma site compared favorably with other passive samplers and a continuous ammonia monitoring instrument.

This is an issue for As super(V) because its trivalent metabolites have unique toxicities and relatively greater potency compared to their pentavalent counterparts for many endpoints. In this study, dose-dependency in tissue distribution and urinary excretion for inorganic arsenic and its methylated metabolites was assessed in female C57Bl/6 mice exposed to 0, 0.5, 2, 10 or 50 ppm arsenic (as arsenate, As super(V)) in their drinking water for 12 weeks. No adverse effects were observed and body weight gain did not differ significantly among groups. Urinary excretion of arsenite monomethylarsonous acid (MMA super(I) super(I) super(I)), dimethylarsinous acid (DMA super(I) super(I) super(I)), dimethylarsinic acid (DMA super(V)), and trimethylarsine oxide (TMAO) increased linearly with dose, whereas As super(V) and monomethylarsonic acid (MMA super(V)) excretion was non-linear with respect to dose. Total tissue arsenic accumulation was greatest in kidney>lung>urinary bladder?skin>blood>liver. Monomethyl arsenic (MMA, i.e. MMA super(I) super(I) super(I)+MMA super(V)) was the predominant metabolite in kidney, whereas dimethylarsenic (DMA, i.e., DMA super(I) super(I) super(I)+DMA super(V)) was the predominant metabolite in lung. Urinary bladder tissue had roughly equivalent levels of inorganic arsenic and dimethylarsenic, as did skin. These data indicate that pharmacokinetic models for arsenic metabolism and disposition need to include mechanisms for organ-specific accumulation of some arsenicals and that urinary metabolite profiles are not necessarily reflective of target tissue dosimetry.

Methods and Results:Strains of M. avium (n=3) and Mycobacterium intracellulare (n=2) were exposed to LP-UV, and log sub(10) inactivation and inactivation kinetics were evaluated. All strains exhibited greater than 4 log sub(10) inactivation at fluences of less than 20mJcm super(-2). Repair potential was evaluated using one M. avium strain. Light repair was evaluated by simultaneous exposure using visible and LP-UV irradiation. Dark repair was evaluated by incubating UV-exposed organisms in the dark for 4h. The isolate did not exhibit light or dark repair activity. Conclusions:Results indicate that MAC organisms are readily inactivated at UV fluences typically used in drinking water treatment. Differences in activation kinetics were small but statistically significant between some tested isolates. Significance and Impact of the Study:Results provide LP-UV inactivation kinetics for isolates from the relatively resistant MAC. Although UV inactivation of Mycobaterium species have been reported previously, data collected in this effort are comparable with recent UV inactivation research efforts performed in a similar manner. Data were assessed using a rigorous statistical approach and were useful towards modelling efforts.

This analysis can be complicated by seemingly incongruent data from different model runs, model types, and field measurements. Here we present a case study example that describes how to identify trends in regional scale mercury deposition using best-available information from multiple data sources. To do this, we use data from three atmospheric chemistry models (CMAQ, GEOS-Chem, HYSPLIT) and multiple sediment archives (ombrotrophic bog, headwater lake, coastal salt marsh) from the Bay of Fundy region in Canada. Combined sediment and modeling data indicate that deposition attributable to US and Canadian emissions has declined in recent years, thereby increasing the relative significance of global sources. We estimate that anthropogenic emissions in the US and Canada account for 28-33% of contemporary atmospheric deposition in this region, with the rest from natural (14-32%) and global sources (41-53%).

Grasses from Kentucky and Minnesota; forest shrubs from California and Florida; and pine forest biomass from the Piedmont region of North Carolina, western North Carolina, and coastal Oregon were collected and tested in a burn facility that mimicked a prescribed fire in the natural environment scenario. Ambient sampling methods for PCDD/F were variously accompanied by real-time measurements of major aromatic species, including benzene, toluene, naphthalene, and styrene. Emission factors in mass of toxic equivalent (TEQ) of PCDD/F per kg of carbon burned (kg sub(C) sub(b)) for the two grasses averaged 0.32ng TEQ /kg sub(C) sub(b). Burn tests (n=27) on forest biomass from the five sources show PCDD/F emission factors ranging from 0.3 to 26.3ng TEQ /kg sub(C) sub(b), with a mean and median of 5.8 and 3.3ng TEQ/kg sub(C) sub(b), respectively. Variation of the forest green/brown needle content, sample size, burn scenario, and facility ventilation rate showed no consistent effects on PCDD/F emissions. For forest burns, 30-35% of the PCDD and 50-55% of the PCDF emissions occurred during the flaming period from 0 to 5min, while the highest emission factors (per mass of carbon burned) were recorded during the smoldering period from 5 to 60min. Emissions of PCDD/F exceeded those present in the raw biomass by a factor of four, confirming PCDD/F formation from combustion rather than from simple surface volatilization. The majority of the PCDD/F partitions to the emissions rather than the ash.

AN - 19492906; 8645618 AB - 1. Species-discharge relationships (SDR) are aquatic analogues of species-area relationships, and are increasingly used in both basic research and conservation planning. SDR studies are often limited, however, by two shortcomings. First, they do not determine whether reported SDRs, which normally use complete drainage basins as sampling units, are scale dependent. Second, they do not account for the effects of habitat diversity within or among samples.2. We addressed both problems by using discrete fish zones as sampling units in a SDR analysis. To do so, we first tested for longitudinal zonation in three rivers in the southeastern U.S.A. In each river, we detected successive 'lower', 'middle', and 'upper' fish zones, which were characterized by distinct fish assemblages with predictable habitat requirements. Because our analyses combined fish data from multiple sources, we also used rarefaction and Monte Carlo simulation to ensure that our zonation results were robust to spurious sampling effects.3. Next, we estimated the average discharge within each zone, and plotted these estimates against the respective species richness within each zone (log sub(10) data). This revealed a significant, linear SDR (r super(2)=0.83; P<0.01). Notably, this zonal SDR fit the empirical data better than a comparable SDR that did not discriminate among longitudinal zones. We therefore conclude that the southeastern fish SDR is scale dependent, and that accounting for within-basin habitat diversity is an important step in explaining the high diversity of southeastern fishes.4. We then discuss how our zonal SDR can be used to improve conservation planning. Specifically, we show how the slope of the SDR can be used to forecast potential extinction rates, and how the zonal data can be used to identify species of greatest concern.

AN - 69698825; 18814879 AB - This research describes the development of a supercritical fluid extraction (SFE) method to recover aflatoxin B(1) from fortified soil. The effects of temperature, pressure, modifier (identity and percentage), and extraction type were assessed. Using the optimized SFE conditions, the mean recovery from air dried soil was 72%. The variables associated with changes in recovery of aflatoxin were co-solvents, static extraction, and temperature. Acetonitrile-2% acetic acid, used both in-cell and on-line, provided the most efficient recovery. The results indicate that desorption from the soil was the limiting factor in recovery and that the static phase was more important than the dynamic. JF - Journal of chromatography.

Most of the intermediates reported herein have not been found in prior studies. Results indicate that MC-LR degradation is initiated at four sites of the toxin; three on the Adda amino acid (aromatic ring, methoxy group, and conjugated double bonds) and one on the cyclic structure (Mdha amino acid). Several intermediates gave multiple peaks in the TIC (m/z = 1011.5, 1029.5, 1063.5), which were deduced to be geometrical or constitutional isomers. This is the first study that reports the hydroxylation of the aromatic ring and the demethoxylation of MC-LR with TiO2 photocatalysis. The most targeted site was the conjugated diene bonds because of their location in the MC-LR structure. Isomerization at the C4-C5 and C6-C7 of the diene bond of the Adda chain was a direct result of hydroxyl radical addition/substitution. Based on the above, we concluded that oxidation and isomerization of the diene bonds of MC-LR occurred simultaneously. Other steps included hydroxyl substitution, further oxidation, and bond cleavage. As the reaction time progressed, simultaneous oxidation of the Adda chain and the cyclic structure occurred.

8713068 AB - Differential susceptibility among reef-building coral species can lead to community shifts and loss of diversity as a result of temperature-induced mass bleaching events. We evaluate environmental influences on coral colony bleaching over an 8-year period in the Florida Keys, USA. Clustered binomial regression is used to develop models incorporating taxon-specific responses to the environment in order to identify conditions and species for which bleaching is likely to be severe. By building three separate models incorporating environment, community composition, and taxon-specific responses to environment, we show observed prevalence of bleaching reflects an interaction between community composition and local environmental conditions. Environmental variables, including elevated sea temperature, solar radiation, and reef depth, explained 90% and 78% of variability in colony bleaching across space and time, respectively. The effects of environmental variables were only partially explained (33% of variability) by corresponding differences in community composition. Taxon-specific models indicated individual coral species responded differently to local environmental conditions and had different sensitivities to temperature-induced bleaching. For many coral species, but not all, bleaching was exacerbated by high solar radiation. A 25% reduction in the probability of bleaching in shallow locations for one species may reflect an ability to acclimatize to local conditions. Overall, model results indicate predictions of coral bleaching require knowledge of not just the environmental conditions or community composition, but the responses of individual species to the environment. Model development provides a useful tool for coral reef management by quantifying the influence of the local environment on individual species bleaching sensitivities, identifying susceptible species, and predicting the likelihood of mass bleaching events with changing environmental conditions.

AN - 69666346; 18671993 AB - A large amount of evidence suggests that arsenicals act via oxidative stress in causing cancer in humans and experimental animals. It is possible that arsenicals could bind in situ close to nuclear DNA followed by Haber-Weiss type oxidative DNA damage. Therefore, we tested this hypothesis by using radioactive (73)As labeled arsenite and vacuum filtration methodology to determine the binding affinity and capacity of (73)As arsenite to calf thymus DNA and Type 2A unfractionated histones, histone H3, H4 and horse spleen ferritin. Arsenicals are known to release redox active Fe from ferritin. At concentrations up to about 1 mM, neither DNA nor any of the three proteins studied, Type II-A histones, histone H3, H4 or ferritin, bound radioactive arsenite in a specific manner. Therefore, it appears highly unlikely that initial in situ binding of trivalent arsenicals, followed by in situ oxidative DNA damage, can account for arsenic's carcinogenicity. This experimental evidence (lack of arsenite binding to DNA, histone Type II-A and histone H3, H4) does not rule out other possible oxidative stress modes of action for arsenic such as (a) diffusion of longer lived oxidative stress molecules, such as H(2)O(2) into the nucleus and ensuing oxidative damage, (b) redox chemistry by unbound arsenicals in the nucleus, or (c) arsenical-induced perturbations in Fe, Cu or other metals which are already known to oxidize DNA in vitro and in vivo.

In this study, breast milk collected from seven countries in Asia was analyzed (n = 184) for nine PFCs, including perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA). In addition, five brands of infant formula (n = 21) and 11 brands of dairy milk (n = 12) collected from retail stores in the United States were analyzed, for comparison with PFC concentrations previously reported for breast milk from the U.S. PFOS was the predominant PFC detected in almost all Asian breast milk samples, followed by perfluorohexanesulfonate (PFHxS) and PFOA. Median concentrations of PFOS in breast milk from Asian countries varied significantly; the lowest concentration of 39.4 pg/mL was found in India, and the highest concentration of 196 pg/mL was found in Japan. The measured concentrations were similar to or less than the concentrations previously reported from Sweden, the United States, and Germany (median, 106-166 pg/mL). PFHxS was found in more than 70% of the samples analyzed from Japan, Malaysia, Philippines, and Vietnam, at mean concentrations ranging from 6.45 (Malaysia) to 15.8 (Philippines) pg/mL. PFOA was found frequently only in samples from Japan; the mean concentration for that country was 77.7 pg/mL. None of the PFCs were detected in the infant-formula or dairy-milk samples from the U.S. except a few samples that contained concentrations close to the limit of detection. The estimated average daily intake of PFOS by infants from seven Asian countries, via breastfeeding, was 11.8 c 10.6 ng/kg bw/day; this value is 7-12 times higher than the estimated adult dietary intakes previously reported from Germany, Canada, and Spain. The average daily intake of PFOA by Japanese infants was 9.6 c 4.9 ng/kg bw/day, a value 3-10 times greater than the estimated adult dietary intakes reported from Germany and Canada. The highest estimated daily intakes of PFOS and PFOA by infants from seven Asian countries studied were 1-2 orders of magnitude below the tolerable daily intake values recommended by the U.K. Food Standards Agency.

AN - 69748974; 18847467 AB - Pseudomonas aeruginosa (P. aeruginosa) is the most common opportunistic pathogen implicated in nosocomial infections and in chronic lung infections in cystic fibrosis patients. Ortho-phenylphenol (OPP) is an antimicrobial agent used as an active ingredient in several EPA registered disinfectants. Despite its widespread use, there is a paucity of information on its target molecular pathways and the cellular responses that it elucidates in bacteria in general and in P. aeruginosa in particular. An understanding of the OPP-driven gene regulation and cellular response it elicits will facilitate more effective utilization of this antimicrobial and possibly lead to the development of more effective disinfectant treatments. Herein, we performed a genome-wide transcriptome analysis of the cellular responses of P. aeruginosa exposed to 0.82 mM OPP for 20 and 60 minutes. Our data indicated that OPP upregulated the transcription of genes encoding ribosomal, virulence and membrane transport proteins after both treatment times. After 20 minutes of exposure to 0.82 mM OPP, genes involved in the exhibition of swarming motility and anaerobic respiration were upregulated. After 60 minutes of OPP treatment, the transcription of genes involved in amino acid and lipopolysaccharide biosynthesis were upregulated. Further, the transcription of the ribosome modulation factor (rmf) and an alternative sigma factor (rpoS) of RNA polymerase were downregulated after both treatment times. Results from this study indicate that after 20 minutes of exposure to OPP, genes that have been linked to the exhibition of anaerobic respiration and swarming motility were upregulated. This study also suggests that the downregulation of the rmf and rpoS genes may be indicative of the mechanism by which OPP causes decreases in cell viability in P. aeruginosa. Consequently, a protective response involving the upregulation of translation leading to the increased synthesis of membrane related proteins and virulence proteins is possibly induced after both treatment times. In addition, cell wall modification may occur due to the increased synthesis of lipopolysaccharide after 60 minutes exposure to OPP.

2011-033201 AB - Flue gas from coal combustion contains significant amounts of volatile elements such arsenic (As), selenium (Se) and mercury (Hg), which could lead to serious environmental health risks. The capture of these toxic elements in the scrubber with a flue gas desulfurization (FGD) technique has resulted in generation of a metal-laden residue. Since FGD residues are being increasingly used in a variety of beneficial reuse applications, it is important to determine metal speciation and mobility to understand the environmental impact of its reuse. In this paper, we report the solid phase speciation of As, Se and Hg in FGD residues using X-ray absorption spectroscopy (XAS), X-ray fluorescence spectroscopy (XRF), and sequential chemical extraction (SCE) techniques. The SCE results indicated a strong possibility of As association with iron oxides, while Se was distributed among all geochemical phases. Hg appeared to be mainly distributed in the strong-complexed phase. XAS analysis indicated that As existed in its oxidized state (As (V)) while Se and Hg was observed in primarily reduced states as selenite (Se (IV)) and Hg(I), respectively. XRF images suggest a strong association of Hg and As with Fe oxide materials within FGD residues. The results from the SCE tests and leaching studies at different pH conditions indicated that the labile fractions of As, Se and Hg were fairly low and thus suggestive of their stability in the FGD residues. However, the presence of a fine fraction enriched in metal content in the FGD suggested that size fractionation of the FGD residues is important in assessing the environmental risks associated with their reuse.

Iron flocculates often exist in springs and seeps near old landfills due to the vertical relief of the sites. Groundwaters downgradient from old, unlined landfills can be quite reducing due to the influence of landfill leachate and can mobilize naturally occurring arsenic from natural soils. Mobilized Arsenic can be observed from the elevated groundwater concentrations in monitoring wells downgradient from old landfills. There are more than 200 inactive municipal solid waste landfills in the seven counties of New York's lower Hudson region. The majority of these facilities are unlined landfills which were operated by municipalities, and about three quarters of these do not have any groundwater monitoring programs in place. The combination of large numbers of old landfills with the increasing occurrence of new housing developments nearby suggests that there is potential for unregulated private wells to be tapping into arsenic-rich groundwater. Finding and sampling seeps with iron flocculates is an attractive alternative for tracing landfill-mobilized arsenic, since it is relatively easy compared to sinking monitoring wells. Preliminary data from landfills in Maine, Massachusetts and New York's lower Hudson region suggest that flocculates show promise as a simple, cheap assessment tool. The As concentration in flocculates adjacent to landfills varies from 2 to 628 ppm, and the As/Fe ratio in the flocculates appears roughly indicative of groundwater As concentrations in the plumes downgradient of impacted monitoring wells. More work needs to be done to understand the relationship of flocculate chemistry to that of heterogeneous groundwater plumes.

To assess this possibility, we measured lead isotope ratios and multi-element concentrations using High Resolution-ICPMS on archived precipitation samples that were collected over a 15 month sampling period (July 1995-November 1996) at Bondville, Illinois. Unique attributes of this sample site in central Illinois included proximity to Pb smelters (providing a fingerprint for Pb and other metals from point sources in southeast Missouri) which could be contrasted to urban emissions (Chicago and Indianapolis areas) and regional emissions from coal fired power plants. Methods development work for the HR-ICPMS analysis indicated that high precision lead isotope ratios from the precipitation samples could be achieved "as is", with no need for column chemistry or other clean up steps, on samples with lead concentrations as low as 200 ppt, and with total sample consumption of less than one ml. Cluster analysis on Hy-split based meteorological data allowed the precipitation samples to be parsed into six distinct groupings. Major differences in lead isotope and elemental ratios were found to correspond with the meteorological cluster analysis results. We used the coupled meteorology and geochemical techniques to then calculate a precipitation based mass balance for lead and other elements, to apportion smelter derived lead from other natural and anthropogenic sources. Although impacts from smelter derived lead were substantial, impacts from urban areas were the predominant lead source in central Illinois in the mid 1990s. This example of the use of hybrid methods for source apportionment, suggests future studies contrasting past versus present metal emission, transport, and deposition processes using archived precipitation samples are feasible.

Breakthrough curves generated from tracer tests are typically positively-skewed and often exhibit multiple peaks. The persistent skewness is commonly attributed to immobile-flow regions that have been confirmed by numerous studies but the cause of multipeaked breakthrough curves remains elusive. Multiple peaks are sometimes ascribed to tracer entry into ramiform auxiliary channels that become confluent downstream with main channel flow but supporting evidence for such diverging-converging flow is not strong. In order to understand the circumstances under which multipeaked positively skewed breakthrough curves occur, physical experiments utilizing single- and multiple-flow channels were conducted. Simulation also included waterfalls, short-term solute detention in pools, and flow obstructions. Results of the experiments demonstrated that breakthrough curve skewness always occurs but is magnified as immobile-flow regions are encountered. Multiple breakthrough curve peaks occurred when main channel blockages forced divergence of solute into auxiliary channels but also when waterfalls and detention in pools occurred. These results suggest that a greater degree of insight into the shape of breakthrough curves is necessary to better assess the type of mathematical model to apply. Various solute-transport models have been explored to see which best represents the data. These models mainly focused on double-porosity formulations with differing mass-transfer functions. A triple-porosity formulation is currently being investigated.

AN - 69944168; 18593216 AB - Environmental assessmen practices have not been as successful as they should be. We believe that this is in part because environmental assessors lack a clear and useful set of principles-that is, a theory of practice. We propose a theory that derives 19 principles from 3 axioms: (1) assessments inform environmental management decisions, (2) assessments are science based, and (3) management decisions accommodate multiple goals and constraints. The 1st axiom leads to principles that change the focus from good assessments to good decisions. The 2nd focuses assessments on the scientific needs of the decision maker rather than making policy judgments or consensus building. The 3rd axiom leads to integration across disciplines, scales, and types of evidence. This theory of assessment practice implies the need for a new framework for environmental assessment that is more integrative than existing frameworks and more focused on making decisions that resolve environmental problems. We believe that this theory of environmental assessment can lead to clear assessment practices that compel beneficial and confident environmental management.

AN - 69942498; 18630992 AB - In the United States, ambient aquatic life water quality criteria are derived using guidelines developed in 1985 that include a clear and consistent methodology using data from standard toxicity tests. The methodology from these guidelines has been successful, but a broader methodology is needed because some effects of pollutants do not lend themselves to conventional toxicity testing. Criterion assessment is proposed as that methodology. In criterion assessment, a specific environmental goal is translated into a measurable benchmark of effect that is used together with a modeled exposure-response relationship to estimate a range of exposures that will achieve the specific goal. The model of the exposure-response relationships and the benchmark effect are developed from field data and laboratory data using multiple analytical methods. Then the model is solved for the effect, thereby estimating the criterion, an upper threshold for acceptable exposures. The resulting candidate criteria are synthesized to select criteria and other benchmark values, such as remedial goals. The criterion assessment process is illustrated using the US Environmental Protection Agency Framework for Developing for Suspended and Bedded Sediments Water Quality Criteria, which recommends developing alternative candidate criterion values and then evaluating them to select a final criterion. Candidate criteria may be derived from models of field observations, field manipulations, laboratory tests, or empirical and theoretical models. Final selection of a criterion uses a weight-of-evidence comparison that engenders confidence because causal associations are confirmed on the basis of different assumptions, independent data sets, and varied statistical methods, thereby compensating for the concerns raised by individual studies and methods. Thus, it becomes possible to specify criteria for agents with biological or physical modes of action, as well as those with chemical modes of action, to best achieve environmental goals.

AN - 69941871; 18593215 AB - Criteria for the quality of water and other media are often said to be risk based. However, the relationship between the process of criterion setting and risk assessment has not been clear. This article shows that the conventional framework for risk assessment may be easily modified to represent criterion development. The critical difference is that conventional risk assessments solve an exposure-response model for an expected exposure to estimate an effect, but criterion assessments solve the same model for a benchmark effect to estimate an upper limit to acceptable exposures. Hence, the critical step in criterion setting is the determination of an effect metric that can be modeled and that represents the environmental goal. The same process applies to equivalent assessments, such as deriving screening benchmarks and remedial goals.

AN - 69917334; 19106441 AB - The contaminants of concern for smelting and mining sites include arsenic (As), cadmium (Cd), lead (Pb) and zinc (Zn). Risk assessments for such sites need to consider whether toxicity values can be developed for this mixture, and if not, whether interactions among the individual components are significant and can be incorporated quantitatively into the assessment. No information is available for the risk characterization of the toxic interactions of AsCdPbZn mixtures. Studies of the AsCdPb and CdPbZn mixtures supported the assumption that a reasonable approximation to the toxicity of a mixture can be achieved by considering the binary submixtures. Data relevant to long-term simultaneous exposure to binary submixtures were not conclusive. For example, data from animal and human studies of Zn and Pb suggested that moderately elevated Zn intakes may slightly inhibit Pb absorption and haematological effects in children who have deficient or marginal Zn intakes, but were not adequate for adjusting absorption parameters in the Integrated Exposure Uptake Biokinetic (IEUBK) model for Pb. Thus the existing database calls for plausible approaches for risk characterization and considerations in the data usage for such characterization. This article is an attempt to identify such data gaps and the scientific considerations for such efforts.

AN - 69914978; 19108043 AB - Traditionally, chronic toxicity in aquatic organisms and wildlife has been determined from either toxicity test data, acute to chronic ratios, or application of safety factors. A more recent alternative approach has been to estimate chronic toxicity by modeling the time course of mortality as determined in standard acute toxicity tests, but these approaches have received limited validation. The accuracy of chronic toxicity estimates from two time-response models, linear regression analysis (LRA) and accelerated life testing (ALT), was investigated using a dataset of more than 150 matched species pairs of standard acute toxicity test data and measured chronic no-observed-effect concentrations (NOECs). Chronic survival was more accurately modeled by both ALT (accuracy, 69%) and LRA (accuracy, 76%) than was reproduction, growth, or the most sensitive endpoint (accuracy, 50-60%). In general, LRA estimates of chronic toxicity were less conservative than ALT estimates, with 66 to 79% of LRA estimates being greater than the measured NOEC. Acute datasets with early mortality produced estimates of chronic survival that were more accurate (ALT, 92%; LRA, 89%) compared to all datasets but were less conservative (84% of ALT estimates were overestimated vs 93% of LRA estimates). Acute datasets with late mortality resulted in poor ALT and LRA estimates of chronic toxicity for all endpoints. Additional survival time measurements did not improve the accuracy of ALT or LRA estimates of chronic toxicity over the standard four acute measurement times (24, 48, 72, and 96 h). The time course of mortality should be considered when applying time-response models to estimate chronic aquatic toxicity, with greater accuracy likely for chronic survival than for growth or reproduction.

AN - 69703919; 18949836 AB - Phthalate esters are high production volume chemicals used to impart flexibility to polyvinyl chloride products as well as other applications. In the male laboratory rat, the period of sexual differentiation in utero is particularly sensitive to certain phthalate esters, which induce a suite of reproductive malformations, including epididymal and gubernacular agenesis. The fetal rat testes are a main target for phthalate esters as evidenced by a reduction in testosterone production and insulin-like hormone 3 (insl3) expression, a peptide hormone critical for testis descent. Histopathology of fetal and postnatal testes reveals that in utero exposure to phthalate esters disrupts Leydig and Sertoli cell maturation leading to a reduction in germ cells in the malformed seminiferous tubules in adulthood as well as an increased incidence of multinucleated germ cells. There are some strain-specific differences in the target organs in the male reproductive tract in rats affected by phthalate esters. Mixtures of phthalate esters with one another and with other anti-androgenic compounds exhibit cumulative, largely dose-additive effects on male reproductive tract development when administered during sexual differentiation in utero. Since phthalate ester metabolites are detected in maternal and fetal body fluids, and androgen-signaling and insl3 are highly conserved among mammals, phthalates may potentially affect human reproductive development.

AN - 69692115; 18763812 AB - Recently, much emphasis has been placed on understanding the toxic mode of action of the 1,2,4-triazole fungicides (i.e., conazoles) in an effort to improve and harmonize risk assessment. Relative to other conazoles, triadimefon is unique with respect to tumorigenesis in rodents, and it has been proposed that triadimefon does not share a common mechanism of toxicity with other conazoles. We postulate that one reason for this difference is that while many conazoles are metabolized via an oxidative P450-mediated pathway, triadimefon is not. In studies conducted with rat hepatic microsomes, triadimenol was identified as the major metabolite (approximately 80%) of triadimefon metabolism, and reduction of the carbonyl group in triadimefon occurred stereoselectively with preferential formation of the less toxic triadimenol B diastereomer. Using chemical inhibitors of P450s (i.e., clotrimazole and 1-aminobenzotriazole) and carbonyl reducing enzymes (i.e., glycyrrhetinic acid, quercitrin, and cortisone), both triadimefon depletion and triadimenol formation were found to be mediated by 11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1). Studies examining NADPH production and inhibitor studies for glucose-6-phosphate translocation across the endoplasmic reticulum (ER) membrane implicated hexose-6-phosphate dehydrogenase (H6PDH) in the metabolism of triadimefon as well. These results ultimately associate triadimefon metabolism not only with steroidogenesis (i.e., 11 beta-HSD1) but carbohydrate metabolism (i.e., H6PDH) as well. Considering the impact of triadimefon on these biochemical pathways may help explain some of triadimefon's unique toxicological effects relative to other conazole fungicides.

AN - 69690326; 18939776 AB - Many units in public housing or other low-income urban dwellings may have elevated pesticide residues, given recurring infestation, but it would be logistically and economically infeasible to sample a large number of units to identify highly exposed households to design interventions. Within this study, our aim was to devise a low-cost approach to identify homes in public housing with high levels of pesticide residues, using information that would allow the housing authority and residents to determine optimal strategies to reduce household exposures. As part of the Healthy Public Housing Initiative, we collected environmental samples from 42 public housing apartments in Boston, MA, in 2002 and 2003 and gathered housing characteristics; for example, household demographics and self-reported pesticide use information, considering information available with and without a home visit. Focusing on five organophosphate and pyrethroid pesticides, we used classification and regression tree analysis (CART) to disaggregate the pesticide concentration data into homogenous subsamples according to housing characteristics, which allowed us to identify households and associated networks impacted by the mismanagement of pesticides. The CART analysis demonstrated reasonable sensitivity and specificity given more extensive household information but generally poor performance using only information available without a home visit. Apartments with high concentrations of cyfluthrin, a pyrethroid of interest given that it is a restricted use pesticide, were more likely to be associated with Hispanic residents who resided in their current apartment for more than 5 yr, consistent with documented pesticide usage patterns. We conclude that using CART as an exploratory technique to better understand the home characteristics associated with elevated pesticide levels may be a viable approach for risk management in large multiunit housing developments.

AN - 69672196; 18715598 AB - Colonies of reef-building stony corals at 57 stations around St. Croix, US Virgin Islands were characterized by species, size and percentage of living tissue. Taxonomic, biological and physical indicators of coral condition were derived from these measurements and assessed for their response to gradients of human disturbance-a requirement for indicators used in regulatory assessments under authority of the Clean Water Act. At the most intensely disturbed location, five of eight primary indicators were highly correlated with distance from the source of disturbance: Coral taxa richness, average colony size, the coefficient of variation of colony size, total topographic coral surface area, and live coral surface area. An additional set of exploratory indicators related to rarity, reproductive and spawning mode and taxonomic identity were also screened. The primary indicators demonstrated sufficient precision to detect levels of change that would be applicable in a regional-scale regulatory program.

AN - 69611479; 18821421 AB - As a discipline of public health, environmental health science is the study of the linkage from environmental pollution sources to eventual adverse health outcome. This progression may be divided into two components, (1) "exposure assessment," which deals with the source terms, environmental transport, human exposure routes, and internal dose, and (2) "health effects," which deals with metabolism, cell damage, DNA changes, pathology, and onset of disease. The primary goal of understanding the linkage from source to health outcome is to provide the most effective and efficient environmental intervention methods to reduce health risk to the population. Biomarker measurements address an individual response to a common external environmental stressor. Biomarkers are substances within an individual and are subdivided into chemical markers, exogenous metabolites, endogenous response chemicals, and complex adducts (e.g., proteins, DNA). Standard biomarker measurements are performed in blood, urine, or other biological media such as adipose tissue and lavage fluid. In general, sample collection is invasive, requires medical personnel and a controlled environment, and generates infectious waste. Exploiting exhaled breath as an alternative or supplement to established biomarker measurements is attractive primarily because it allows a simpler collection procedure in the field for numerous individuals. Furthermore, because breath is a gas-phase matrix, volatile biomarkers become more readily accessible to analysis. This article describes successful environmental health applications of exhaled breath and proposes future research directions from the perspective of U.S. Environmental Protection Agency (EPA) human exposure research.

AN - 69587307; 18601943 AB - Zinc is a common metal in most ambient particulate matter (PM), and has been proposed to be a causative component in PM-induced adverse cardiovascular health effects. Zinc is also an essential metal and has the potential to induce many physiological and nonphysiological changes. Most toxicological studies employ high levels of zinc. We hypothesized that subchronic inhalation of environmentally relevant levels of zinc would cause cardiac changes in healthy rats. To address this, healthy male WKY rats (12 weeks age) were exposed via nose only inhalation to filtered air or 10, 30 or 100 microg/m(3) of aerosolized zinc sulfate (ZnSO(4)), 5 h/day, 3 days/week for 16 weeks. Necropsies occurred 48 h after the last exposure to ensure effects were due to chronic exposure rather than the last exposure. No significant changes were observed in neutrophil or macrophage count, total lavageable cells, or enzyme activity levels (lactate dehydrogenase, n-acetyl beta-D-glucosaminidase, gamma-glutamyl transferase) in bronchoalveolar lavage fluid, indicating minimal pulmonary effect. In the heart, cytosolic glutathione peroxidase activity decreased, while mitochondrial ferritin levels increased and succinate dehydrogenase activity decreased, suggesting a mitochondria-specific effect. Although no cardiac pathology was seen, cardiac gene array analysis indicated small changes in genes involved in cell signaling, a pattern concordant with known zinc effects. These data indicate that inhalation of zinc at environmentally relevant levels induces cardiac effects. While changes are small in healthy rats, these may be especially relevant in individuals with pre-existent cardiovascular disease.

AN - 66708746; 19404873 AB - It has long been known that the developing immune system is more sensitive and susceptible than the adult immune system to some drugs and environmental contaminants. However, notable advances have been made in the database of studies supporting developmental immunotoxicity (DIT) over the past 5 years. There is considerable evidence that responses of the immune system can be quantitatively or qualitatively different from normal adult responses when xenobiotic exposure occurs during critical periods of immune system development. Qualitative differences of DIT relative to adult exposures include examples of more persistent effects, a latency of effects, and immune dysfunction that is fundamentally different than effects observed when adults are exposed. A symposium was presented at the Society of Toxicology annual meeting to provide an update on advances in the maturing field of developmental immunotoxicology and to facilitate discussion on the range of DIT and later life effects following developmental exposure. In particular, presentations focused on implications of neuroendocrine cross-talk for DIT, the association between developmental air pollutant exposure and asthma, and recent evidence that developmental exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin may increase the risk of autoimmune responses. Several important concepts relative to DIT assessment were illustrated, i.e., (1) Screening for immunosuppression alone is not sufficient to identify all potential immunotoxic effects; (2) DIT cannot be reliably predicted from studies that only utilize adult exposures; (3) Functional testing protocols are preferred in the assessment of DIT; (4) Gender-related differences should be routinely assessed; (5) Latency (i.e., later-life adverse outcomes resulting from developmental exposures) is an important consideration that cannot be detected in adult exposure studies; and, (6) There is increasing support for DIT testing protocols with continuous exposure throughout development until the immune assay is performed.

Representatives in regional & local employment councils -- among others the labor market organizations -- have become advisory to the new employment regions & local job centres, & are supposed to supervise & monitor the results & effects of the responsible authorities. These are fundamentally different tasks & duties than their predecessors, the regional labor market councils & local coordination committees. During the political preparation of the local government reform the main labor market organizations strongly criticized the planned steering structure. They argued that the new advisory structure would undermine the unique Danish tradition of administrative corporatism & the commitment & responsibility of the labor market organizations, which could potentially reduce the legitimacy of employment policies. In this article we present data from a survey of all members of the new local employment councils (response rate, 52 %) & the secretariats of the councils (response rate, 77 %). The survey focuses on the actions & reactions of the local member representatives in the councils (representatives of the trade union confederation, employers association, municipal representatives, general practitioners association, disability associations etc.). We find that that there is some discrepancy between the sceptical attitude of the main organizations & their local representatives. Respondents suggest that there is a relatively good climate of cooperation, trust, & consensus in the councils, & that the councils have a relatively high degree of influence on local employment policies. Internally, it is mainly representatives of the trade union confederation (Danish LO) that are assessed as the most active & influential participants, while the employers representatives are less active & influential. Despite the relatively positive assessment of the internal functioning of the councils, the respondents tend to agree that the councils have difficulties in finding a distinctive role & platform in the intersection between increasing central state control & municipal autonomy.

TT - Fra arbejdsmarkedspolitik til beskaeftigelsespolitik -- kosmetiske eller indholdsmaessige forskelle? AN - 61686688; 200900592 AB - Ideas & policy recipes travel. Labor market policy seems to have become popular in most places. The active labor market policy implemented in Denmark from 1994 as part of a new policy-mix of general economic policy & selective labor market policy measures has become renown because of the good results achieved & its place as one of the pillars in the Danish "flexicurity" arrangement. Denmark has the status of a role model for the rest of Europe. Activation has been a success formula for reintegrating unemployed people into the open labor market & without doing damage to macro economic goals. The rationale of labor market policy was to build up capacities by the individual wage earner -- e.g. skills & competences -- thereby bringing "the security of the wings" to every member of the labor force. Redistributional elements were part of the policy as well; it was seen as an arrangement of the welfare state that could secure a highly mobile labor market & give more resources & new changes to all people. It is wrong to think that it is the same kind of labor market policy now being conducted in Denmark. There has been not only a cosmetic change in name ("employment policy") but also one of form & practice. Slowly, & without much political debate, the content of labor market policy in Denmark, as well as the processes behind the policy arrangements, has been recalibrated. A new rationale much more in accordance with "work first" -principles & consisting of new supply side oriented elements has been installed. A balance between rights & duties for the unemployed was realized during the 1990es; but during the last five to six years & more discipline & punishment has been introduced. A kind of massage of the consciousness of the individual unemployed is now taking place in 91 new employment service centres as people learn to behave like wage earners with a strong work ethic. This is called a new "identity & behavioral policy." Economic incentives are used instead of education & other activation measures, & both people on unemployment insurance benefits & people on social assistance are treated in ways that should make them understand that it is better to take up every kind of job offer made instead of going into activation & education. Redistributional elements have been screened out of the policy as well. The social partners were strong decision-makers during the 1990es but they have been excluded from the public steering bodies from 2007, now having only an advisory role to play. One can speak of a systemic change. It is ironic, therefore, that the rest of Europe looks to Denmark both to learn & to imitate -- e.g. having mimetic isomorphism established as to labor market policy while Denmark has taken over a traditional supply-side edition of "employment policy" that is of little use to the rest of Europe &, actually. also a threat to Danish flexicurity.

Incidental ingestion is an important exposure pathway in these frameworks for assessing human health exposure and risk associated with contaminated soils. The oral bioavailability of arsenic and other soil contaminants can be determined by conducting dosing trials using acceptable surrogate animal models. To overcome the difficulty and expense associated with in vivo dosing trials, in vitro gastrointestinal (IVG) methods have been developed that simulate human gastrointestinal conditions. Bioaccessible arsenic determined by several IVG methods have been shown to be correlated with in vivo bioavailability data. Soil chemistry, mineralogy, and other geomedia properties influence contaminant bioavailability in urban contaminated soils. The influence of soil chemistry and arsenic source on arsenic bioaccessibility will be presented. Soil and contaminant chemistry requirements necessary for accurate application of IVG methods to access contaminant (bio)availability in urban soils will be presented.

The literature has documented numerous examples of highly contaminated Pb sites at shooting ranges, battery manufacturing facilities, etc treated with various forms of phosphate sources to reduce extractable Pb translating to reduced bioavailability and increased environmental stability. However, few immobilization studies explore the impact of Pb contaminated residential soils with regard to children's health. This presentation will highlight past success stories of metal immobilization in residential settings. In addition, an introduction to a multi-disciplinary collaboration entitled "PAYDIRT" will provide preliminary details for a New Orleans city-wide effort to immobilize metal contaminants in residential, public, and commercial soils coupled with a clean soil cap.

LRBS is the log of the ratio of bed surface geometric mean particle diameter (D (sub gm) ) to critical diameter (D (sub cbf) ) at bankfull flow, based on a modified Shield's criterion for incipient motion that explicitly accounts for reductions in bed shear stress resulting from channel form roughness due to pools and wood. LRBS ranged from -1.9 to +0.54 in streams within the lower quartile of human riparian and basin disturbance, and was substantially lower (-4.2 to -1.1) in streams within the upper quartile of human disturbance. Streams draining relatively erodible sedimentary lithology (sandstone, siltstone) showed greater reductions in LRBS associated with disturbance than did those having more resistant volcanic lithology (basalt) with similar levels of basin and riparian disturbance. Contrary to our expectations, smaller streams had lower LRBS than those with larger drainages at any given level of disturbance. In sedimentary lithology, high-gradient streams had higher LRBS than did low gradient streams of the same size and level of human disturbance, but the opposite was true in volcanic lithology. Correlations between D (sub gm) and land disturbance were stronger than those observed between D (sub cbf) and land disturbance, suggesting that land use has augmented sediment supplies and increased streambed fine sediments in the most disturbed streams. However, we also show evidence that some of the apparent reductions in LRBS in volcanic drainages may have resulted in part from anthropogenic increases in bed shear stress. The EMAP habitat survey data appear adequate to evaluate regional patterns in bed stability and sedimentation and their general relationship to human disturbances.

Previous investigations have examined the dissolution of iron oxides in H (sub 2) S solutions, but these studies focused on sulfide oxidation and iron oxide dissolution kinetics. Mineral phase transformation in the Fe-O-S system has not been explored in detail. This study investigates mineralogical changes during sulfidization of ferrihydrite by hydrogen sulfide and its impact on heavy metal behavior in reducing environments. Preliminary results show that FeS and S (sub 0) formation occurs rapidly through reductive dissolution of ferrihydrite by H (sub 2) S. FeS transformation to FeS (sub 2) is slow at 25 degrees C. However, transformation of FeS to FeS (sub 2) is accelerated at 45 degrees C. Sulfur partitioning results indicate that FeS and FeS (sub 2) are inversely correlated within 21d. XRD shows a decrease in S (sub 0) over time, and S (sub 0) begins to disappear after 14d, which is in agreement with the stabilization of FeS. This indicates that transformation of FeS to FeS (sub 2) is halted due to exhaustion of S (sub 0) . The results suggest that FeS (sub 2) is formed through FeS transformation, instead of direct pyritization of ferrihydrite. Nickel (Ni) is used as an example in this study to demonstrate how sulfidization of iron oxides affects metal partitioning in reducing environments.

Vanadyl (V (super 4+) ) and vanadate (V (super 5+) ) are the most toxic ions and may combine in natural and drinking waters to form a wide range of solids depending on the redox potential and pH. Ingestion of vanadium from drinking water is only recently being considered a potentially serious threat to human health. Vanadium accumulation, up to 1% by weight has been reported for corrosion deposits in lead drinking water pipes from numerous United States public drinking water systems (DWS), indicating a potential reservoir for human exposure if mobilized. This study presents the first detailed examination of vanadium speciation from twenty-one lead pipe corrosions by-products from eight municipal DWS. Six DWS use surface waters and two ground water as their sources. Vanadium concentrations for the samples determined by ICP-OES range from <40 to 8500 ppm. Bulk XANES, on eight samples, identified the presence of vanadinite (Pb (sub 5) (V (super 5+) O (sub 4) ) (sub 3) Cl). Additionally mu XRD or mu XANES analyses on three in-situ lead pipe corrosion by-products indicated the presence of vanadinite and its location. Vanadinite appears to be mainly concentrated at the surface or near-surface portion of the corrosion by-products. Hydraulic dislodgement of scale pieces or chemical breakdown resulting from water treatment changes, could mobilize vanadium and provide an unexpected and unmonitored detrimental human exposure event. The results of this study suggest that treatment processes, redox potential, and pH present in the distribution system are likely to play a key roles in the formation of vanadinite in drinking water pipe scales, as well as the presence of lead premise piping. Thus, it is imperative to further investigate the presence, speciation, and concentration of vanadium in corrosion by-products in order to assess the chemical and physical factors controlling the formation and release of vanadium into drinking water.

These landfills are not lined and are, due to their original siting in local terrain depressions, also partially submerged in ground water. Composition of groundwater during its through-flow and/or by mixing with the percolating recharge from the above will become modified by addition of organic as well as inorganic secondary dissolved substances. Microbial decomposition of DOC's and its need for oxygen acceptors subsequently forms a downstream zoned leachate plumes. In this presentation we will compare metal equilibria in an aquifer downstream from wetlands with equilibria downstream from landfills. Wetland influenced aqueous equilibria are near the stability field of ferric oxi-hydroxides; whereas landfill influenced environments reach toward the Fe-sulfide zone. Metals, including Fe, As, Cr, Co, Cu, Pb, Mn, Ni, and Zn partition between 3 states: (1) sulfides; (2) adsorption onto ferric precipitates; and (3) dissolved aqueous state. Zones of groundwater discharge toward the surface water reservoirs have strong oxidation gradient, contain oxidative re-precipitation of ferric hydroxides, and adsorptive metals enrichment. Multi-elemental correlations of Fe, As, and Ni, Co, Cu, Zn, Pb, Mn within this zone suggest a similar source mobilization as landfill exogenic substances and simple transport mechanism within the wetland influenced aquifer. Lack of such correlations in the area of known seepage points from a discharging landfill plume is either further modified by sulfide precipitations and/or by additions of dissolved metals originating as landfill endogenic components.

We propose a framework that focuses on resolving environmental problems by integrating different types of assessments. Four general types of assessments are included: (1) condition assessments to detect chemical, physical, and biological impairments; (2) causal pathway assessments to determine causes and identify their sources; (3) predictive assessments to estimate environmental, economic, and societal risks, and benefits associated with different possible management actions; and (4) outcome assessments to evaluate the results of the decisions of an integrative assessment. The four types of assessments can be neatly arrayed in a two-by-two matrix based on the direction of analysis of causal relationships (rows) and whether the assessment identifies problems or solves them (columns). We suggest that all assessments have a common structure of planning, analysis, and synthesis, thus simplifying terminology and facilitating communication between types of assessments and environmental programs. The linkage between assessments is based on intermediate decisions that initiate another assessment or a final decision signaling the resolution of the problem. The framework is applied to three cases: management of a biologically impaired river, remediation of a contaminated site, and reregistration of a pesticide. We believe that this framework clarifies the relationships among the various types of assessment processes and their links to specific decisions.

Insufficient information exists for estimating the likelihood of nanomaterial deposition on natural surfaces in aquatic environments. This work develops a framework for estimating potential metal oxide nanomaterial self-aggregation through the combined application of recent developments in diffuse layer model surface complexation theory with historical Derjaguin-Landau-Verwey-Overbeek (DLVO) procedures. Findings from the work include: 1) the surface, diffuse layer, and/or zeta potentials of nanomaterials in environmental aqueous systems are likely to have an absolute value less than 25mV, 2) only nanomaterials with a Hamaker constant as large as 1E-19 J (and an absolute surface potential < 25mV) will likely aggregate in most environmental aquatic media, 3) natural organic matter coatings may render metal oxide nanomaterials less likely to aggregate in aquatic systems, 4) nanomaterials in aqueous suspension will likely have an absolute surface potential less than their micron-sized counterparts of the same composition, and 5) robust diffuse layer model databases of intrinsic surface site reactivity constants with multivalent aqueous environmental ions will need to be developed in order to provide accurate mechanistic estimates of the surface potential of nanoparticles suspended in aqueous environmental systems.

Previous studies estimated forest fragmentation for the continental United States (US). In this study, new temporal land-cover data from the National Land Cover Database (NLCD) were used to estimate changes in forest fragmentation at multiple scales for the continental US. Early and late dates for the land-cover change data were ca. 1992 and ca. 2001. Forest density was used as a multi-scale index of fragmentation by measuring the proportion of forest in neighborhoods ranging in size from 2.25 to 5314.41ha. The multi-scale forest density maps were classified using thresholds of 40% (patch), 60% (dominant), and 90% (interior) to analyze temporal change of fragmentation. The loss of dominant and interior forest showed distinct scale effects, whereas loss of patch forest was much less scale-dependent. Dominant forest loss doubled from the smallest to the largest spatial scale, while interior forest loss increased by approximately 80% from the smallest to the second largest spatial scale, then decreased somewhat. At the largest spatial scale, losses of dominant and interior forest were 5 and 10%, respectively, of their ca. 1992 amounts. In contrast, patch forest loss increased by only 25% from the smallest to largest spatial scale. These results indicate that continental US forests were sensitive to forest loss because of their already fragmented state. Forest loss would have had to occur in an unlikely spatial pattern in order to avoid the proportionately greater impact on dominant and interior forest at larger spatial scales.

Our objective was to identify the organic matter (OM) sources fueling the lower food web in the tidal freshwater and oligohaline portions of the Mattaponi using the stable isotopes of carbon (C) and nitrogen (N). Over 3 years (2002-2004), we measured zooplankton densities and C and N stable isotope ratios during the spring zooplankton bloom. The river was characterized by a May-June zooplankton bloom numerically dominated by the calanoid copepod Eurytemora affinis and cladocera Bosmina freyi. Cluster analysis of the stable isotope data identified four distinct signatures within the lower food web: freshwater riverine, brackish water, benthic, and terrestrial. The stable isotope signatures of pelagic zooplankton, including E. affinis and B. freyi, were consistent with reliance on a mix of autochthonous and allochthonous OM, including OM derived from vascular plants and humic-rich sediments, whereas macroinvertebrates consistently utilized allochthonous OM. Based on a dual-isotope mixing model, reliance on autochthonous OM by pelagic zooplankton ranged from 20% to 95% of production, declining exponentially with increasing river discharge. The results imply that discharge plays an important role in regulating the energy sources utilized by pelagic zooplankton in the upper estuary. We hypothesize that this is so because during high discharge, particulate organic C loading to the upper estuary increased and phytoplankton biomass decreased, thereby decreasing phytoplankton availability to the food web.

Further, most models ignore the effects of species on the release decision. We present a discrete-choice model estimated from stated preference data in which conservation release is a function of the species caught and angler characteristics that include fishing avidity, demographic variables, and three angler orientation measures that assess an angler's catch-and-release ethic, attitude toward fisheries regulations, and need for self-caught fish for food. We then compare our stated preference model predictions for an individual angler with field data on catch-and-release fishing for the same angler. The results provide some important messages for managers. First, all angler characteristics were significant in the discrete-choice model, suggesting that an understanding of angler populations may help predict future catch-and-release behavior. Second, our results suggest that behavioral intent (e.g., stated preference data) is a good indicator of actual behavior, as the model correctly predicts the release decision in 74% of the cases. Finally, species type had a significant effect in the stated preference model as well as on model prediction success when compared with actual behavior. These results should be of interest to managers as they address both the understanding of angler catch-and-release behavior and validity issues concerning behavioral data that is collected from an off-site survey.

A recent call for natural resource professional societies to endorse position statements on economic growth raises questions about how scientific societies can and should effectively contribute to policy development. Taking a stand on policy issues is akin to serving as a policy advocate. We believe that natural resource professionals can most constructively contribute to policy development by conducting rigorous research that is policy relevant and by effectively conveying the results and policy implications of that research to all parties interested in the issue. By actively engaging decisionmakers and providing information on pressing policy issues, professional societies can increase opportunities to be recognized as sources for reliable, unbiased information about natural resources and their management.

Our context is the U.S. public health goal to eliminate pediatric elevated blood lead levels (EBLs) by 2010. DATA SOURCES: National, state, and local exposure assessments over the past half century have identified risk factors for EBLs among U.S. children, including age, race, income, age and location of housing, parental occupation, and season. Data extraction and SYNTHESIS: Recent national policies have greatly reduced lead exposure among U.S. children, but even very low exposure levels compromise children's later intellectual development and lifetime achievement. No threshold for these effects has been demonstrated. Although lead paint and dust may still account for up to 70% of EBLs in U.S. children, the U.S. Centers for Disease Control and Prevention estimates that . 30% of current EBLs do not have an immediate lead paint source, and numerous studies indicate that lead exposures result from multiple sources. EBLs and even deaths have been associated with inadequately controlled sources including ethnic remedies and goods, consumer products, and food-related items such as ceramics. Lead in public drinking water and in older urban centers remain exposure sources in many areas. Conclusions: Achieving the 2010 goal requires maintaining current efforts, especially programs addressing lead paint, while developing interventions that prevent exposure before children are poisoned. It also requires active collaboration across all levels of government to identify and control all potential sources of lead exposure, as well as primary prevention.

Chronic arsenic exposure has been associated with carcinogenic, cardiovascular, neurological and diabetic effects in humans and has been of great public health concern worldwide. In 2001, the U.S. Environmental Protection Agency adopted an arsenic standard of 10 mu g/1 from 50 mu g/1 in drinking water. However, there are still great uncertainties on the health effects of arsenic at low doses. Due to the lack of appropriate animal models for extrapolation to human risk, research needs include a better understanding of the mechanisms of arsenic carcinogenesis and assessing health effects of arsenic in humans at low dose. The major modes of action (MOA) proposed for arsenic effects in humans are increasing oxidative stress, altering signal transduction pathways, inducing DNA and chromosomal damage, affecting DNA repair, promoting cell proliferation, and DNA methylation. The objectives of this research were to apply biomarkers to assess arsenic exposure and cancer risks and identify biomarkers useful for assessing arsenic effects in humans. The residents of Ba Men in Inner Mongolia have been exposed to a wide range of arsenic concentrations via well water and showed adverse health effects. This population provides us with an opportunity to assess the relationships between arsenic exposure and health effects. Based on the proposed MOA, we selected biomarkers to assess potential carcinogenic effects of arsenic in the Inner Mongolia population. A total of 324 Ba Men residents, exposed to arsenic via well water ranging from non-detectable levels to 826 mu g/1 of arsenic participated in this study. Samples of well water, urine and toe nail were collected to assess arsenic exposure and investigate metabolic profiles in urine. Human buccal cells and blood samples were collected and the health effects investigated were arsenic-related dermal effects, DNA fragmentation, micronucleus frequency for chromosomal damage, and mRNA expression of the genes (OGG1 and ERCC1) responsible for DNA repair of oxidative damage and human telomerase reverse transcriptase (hTERT) for cell proliferation. The results showed significant associations between arsenic exposure and increase in DNA damage, micronucleus frequency and gene expression of OGG1 and ERCC1 and hTERT. This paper will report the results of these studies and provide some insights into arsenic MOA and human dose-response data.

Low organic matter soils can be difficult to manage in a greenhouse setting because when soils dry, they contract, causing impeded water infiltration, or when overwatered, poor drainage increases the chances of anaerobic conditions. The purpose of this study was to determine if the results for the vegetative vigor test differed when using either natural or artificial soils. The herbicide sulfometuron methyl was applied 14 d after emergence at 0.1 and 0.0032 of the suggested field application rate. Six plant species were tested, 4 of the common test species, Zea mays (corn), Glycine max (soybean), Avena sativa (oat), and Lactuca sativa (lettuce), and 2 native plants of the Willamette Valley, Oregon prairie, Bromus carinatus (California brome) and Ranunculus occidentalis (western buttercup). Herbicide application rate was the most significant factor in the experiment regardless of soil type. The different soils generally produced different results, even though the 2 native soils, one from Oregon and the other from Maryland, are both acceptable soils for the pesticide registration tests. The plants grown on artificial soil produced results generally between the Oregon and Maryland soil results. This study indicates that artificial soils may produce results similar to or more sensitive than soils currently used in the vegetative vigor test.

Mussel communities examined in four rivers in the upper Tennessee River basin appeared significantly nested. Mussel species distributions were mostly unrelated to differences in immigration and only weakly related to downstream direction, giving some indication of structuring by differences in extinction. Mussel species distributions were not related to the number of fish species used as hosts for mussel larvae. Mussel species were more likely to overlap on common fish hosts; however, the host-use matrix was not nested - groups of mussel species used different sets of host fish species in a pattern that appeared phylogenetically related. Sites with high fish host abundance may support high mussel diversity by promoting the survival of mussel species that are less able to attract and infect hosts. Thus, nestedness in freshwater mussel communities may be driven by the array of host fish resources, combined with differences in species' abilities to use fish hosts. An understanding of the nested pattern in this region can aid conservation of this imperiled fauna.

The influence of spatial structure on population dynamics within river-stream networks is poorly understood. Utilizing spatially explicit analyses of temporal genetic variance, we tested whether persistence of central stonerollers (Campostoma anomalum) reflects differences in habitat quality and location within a highly modified urban catchment in southwestern Ohio, U.S.A.2. Estimates of genetic diversity did not vary with habitat quality. Nevertheless, evidence of weak but temporally stable genetic structure, location-dependent effective population sizes and rates of immigration among sites, together suggest that persistence of central stonerollers within the catchment may be attributable to source-sink dynamics driven by habitat heterogeneity.3. Under this scenario, migrant-pool colonization from areas of relatively high habitat quality in the upper catchment sustains the presence of central stonerollers at degraded sites in the main stem and dampens population subdivision within the catchment. However, because intact habitat is restricted to the upper portion of the catchment, it is not possible to preclude net downstream dispersal as a mechanism contributing to source-sink dynamics. The slight genetic structure that persists appears to reflect weak isolation by distance diminished by high rates of immigration.4. This study suggests that without a systems perspective of the conditions that sustain populations in degraded waterways, environmental assessments may underestimate levels of impairment. Conservation and management of stream fishes could be improved by maintaining habitat in areas that are net exporters of migrants or by remediation of impaired habitat.

However, despite the ubiquity of parasites in most food webs, comparisons of the nutritional quality of prey as a function of infection status are largely absent. We measured the nutritional consequences of chytridiomycete infections in Daphnia, which achieve high prevalence in lake ecosystems (>80%), and tested the hypothesis that Daphnia pulicaria infected with Polycarywn laeve are diminished in food quality relative to uninfected hosts. Compared with uninfected adults, infected individuals were smaller, contained less nitrogen and phosphorus, and were lower in several important fatty acids. Infected zooplankton had significantly shorter carapace lengths (8%) and lower mass (8-20%) than uninfected individuals. Parasitized animals contained significantly less phosphorus (16-18% less by dry mass) and nitrogen (4-6% less) than did healthy individuals. Infected individuals also contained 26-34% less saturated fatty acid and 31-42% less docosahexaenoic acid, an essential fatty acid that is typically low in cladocera, but critical to fish growth. Our results suggest that naturally occurring levels of chytrid infections in D. pulicaria populations reduce the quality of food available to secondary consumers, including planktivorous fishes, with potentially important effects for lake food webs.

Samples upstream of the city of St. Cloud (reference site) had median PFOS concentrations of 8.1 ng/g wet weight (ng/g wet wt), but median levels increased significantly downstream in the Minneapolis-St. Paul urban area, with concentrations from the Pig's Eye Lake site at 26 ng/g wet wt (p=0.0015) and the Spring Lake site at 40 ng/g wet wt (p=0.0004). This latter PFOS concentration is within the advisory range for limiting fish consumption to one meal a week according to the Minnesota Department of Health. Other PFAAs were also found to increase significantly between the reference site and the Minneapolis-St. Paul area, but maximal concentrations remained below 2.0 ng/g wet wt. This study demonstrates the bioaccumulation of PFAAs in a ubiquitous fish species in a major urban area known to have historical inputs of various PFAA compounds. The full extent of this contamination and the potential for accumulation in other species remain to be evaluated.

Following the U.S. EPA's PFC Emissions Vintage Model (PEVM), uncontrolled FC emissions are modeled as proportional to total manufactured layer area (TMLA) of silicon. FC emissions of World Semiconductor Council (WSC) charter member countries (Europe, Japan, Korea, Taiwan and the United States), which voluntarily committed in 1999 to lower FC emissions by 2010 to 10% of baseline year emissions, are modeled for the period 1995-2020. For this same period, emissions from Chinese manufacturers under alternative emission reduction scenarios are modeled. If Chinese manufacturers were to adopt a baseline year of 2005 and a reduction target of 10% below baseline year emissions to be achieved by 2020, emissions would be 3.4 MMTCO sub(2)eq, comparable to the similarly projected controlled emissions of an average WSC charter member country (=16.3/5 MMTCO sub(2)eq) in 2020. The relative stringency of the alternative reduction scenarios considered for China vary between 50 and 95% reduction compared to business as usual (BAU). This is comparable to the stringency of the WSC charter members' goals for which FC emission reduction technologies are currently available.

Affordable passive sampling methods are available for estimating "hot spots" and spatial variations of gaseous dry N deposition (i.e., nitrogen dioxide (NO2) and ammonia (NH3)), though few viable methods for estimating the deposition from nitric acid (HNO3) gas using passive sampling techniques exist. We consider passive sampling approaches for assessing spatial patterns of dry atmospheric N deposition across watersheds. We describe a method for constructing an inexpensive passive sampler (for less than $12 per unit) for monitoring spatial variations in the magnitude of HNO3 in the atmosphere. We demonstrate the applicability of passive samplers for use in watershed biogeochemical research and water quality management through a review of previous applications and via our own case study of the South Korean peninsula.

A study was designed to assess traffic emission impacts on air quality near a heavily traveled highway. The portion of highway studied included a section of open field and a section with a noise barrier adjacent to the road. In addition, the section containing the noise barrier included a portion with vegetation in the vicinity of the barrier. Thus, this field study provided an opportunity to evaluate near-road air quality with no barriers, with a noise barrier only, and with a noise barrier and vegetation adjacent to the road. Pollutants measured under these scenarios included carbon monoxide (CO) and particulate matter (PM). Measurements showed the effects of a noise barrier on near-road air quality. The presence of this structure often led to pollutant concentration reductions behind the barrier during meteorological conditions with winds directionally from the road. CO and PM number concentrations generally decreased between 15 and 50% behind the barrier. However, conditions occurred when pollutant concentrations were greater behind the barrier than when no barrier was present. These results imply that the presence of a noise barrier can lead to higher pollutant concentrations on the road during certain wind conditions. In addition, the study results suggested that the presence of mature trees in addition to the barrier further lowered PM number concentrations.

Five factors were identified: open burning of building debris, smoldering fires from building debris, a mixed recovery source, a sulfate/debris removal source, and motor vehicle exhaust.

The benthic assemblage was dominated by deposit-feeding polychaetes of the families Cirratulidae, Paraonidae, and Cossuridae. Assemblage composition and abundance remained relatively constant over the course of the study, despite seasonal changes in sediment nutritional quality. Constant seawater temperatures and/or relatively long species generation times may account for this pattern. Sediment depth-frequency distributions of cirratulid and paraonid polychaetes varied temporally and exhibited subsurface abundance peaks; depth-frequency distributions of cossurid polychaetes, in contrast, were temporally stable. Subsurface peaks of plant pigment concentrations matched those of the cirratulid and cossurid polychaetes, suggesting that these groups transport and cache recently deposited phytodetritus below the sediment surface. This subsurface caching may ameliorate the effects of a seasonally variable food supply, damping any seasonal response of the fauna.

This investigation, prompted by successful bench-scale ECD of trichloroethylene, involved development, parametric characterization and evaluation of a pilot-scale electrochemical reactor for degradation of calmagite, a sulfonated azo-dye used as a model contaminant. The reactor has two chambers filled with granulated graphite for electrodes. The system has electrical potential, current, conductivity, pH, temperature, water-level and flow sensors for automated monitoring. The reactor supports outdoor and fail-safe venting, argon purging, temperature regulation and auto-shutdown for safety. Treatment involves recirculating the contaminated solution through the electrode beds at small flow velocities mimicking low fluid-flux in groundwater and submarine sediments. The first phase of the investigation involved testing of the reactor components, its parametric probes and the automated data acquisition system for performance as designed. The results showed hydraulic stability, consistent pH behavior, marginal temperature rise (<5 super(o)C) and overall safe and predictable performance under diverse conditions. Near complete removal of calmagite was seen at 3-10V of applied voltage in 8-10h. The effects of voltage and strength of electrolyte on degradation kinetics have been presented. Further, it was observed from the absorption spectra that as calmagite degrades over time, new peaks appear. These peaks were associated with degradation products identified using electrospray ionization mass spectrometry. A reaction mechanism for ECD of calmagite has also been proposed.

Each of these models used the same horizontal modeling grid, pollutant emission information, modeled meteorology, and boundary conditions to the greatest extent practical. Three global-scale atmospheric mercury models were applied to define three separate initial condition and boundary condition (IC/BC) data sets for elemental mercury, reactive gaseous mercury, and particulate mercury air concentrations for use by the regional-scale models. The monthly average boundary concentrations of some mercury species simulated by the global models were found to vary by more than a factor of 10, especially at high altitudes. CMAQ, REMSAD, and TEAM were each applied three times, once for each IC/BC data set, to simulate atmospheric mercury transport and deposition during 2001. This paper describes the study design and shows qualitative model-to-model comparisons of simulation results on an annual basis. The air concentration patterns for mercury simulated by the regional-scale models showed significant differences even when the same IC/BC data set was used. Simulated wet deposition of mercury was strongly influenced by the shared precipitation data, but differences of over 50% were still apparent. Simulated dry deposition of mercury was found to vary between the regional-scale models by nearly a factor of 10 in some locations. Further analysis is underway to perform statistical comparisons of simulated and observed mercury wet deposition using weekly and annual sample integration periods.

Smoke from these fires was observed over the continental United States in satellite images, and a variety of chemical tracers associated with the fires were sampled by aircrafts deployed during the International Consortium for Atmospheric Research on Transport and Transformation field experiment. Several recent studies have quantified the impacts of the long-range transport of pollution associated with these fires on tropospheric CO and O3 levels over the eastern United States. This study quantifies the episodic impact of this pollution transport event on surface-level fine particulate matter (PM2.5) concentrations over the eastern United States during mid-July 2004, through the complementary use of remotely sensed, aloft, and surface measurements, in conjunction with a comprehensive regional atmospheric chemistry-transport model. A methodology is developed to assimilate MODIS aerosol optical depths in the model to represent the impacts of the fires. The resultant model predictions of CO and PM2.5 distributions are compared extensively with corresponding surface and aloft measurements. On the basis of the model calculations, a 0.12Tg enhancement in tropospheric PM2.5 mass loading over the eastern United States is estimated on 19 July 2004 due to the fires. This amount is significantly larger (approximately a factor of 8) than the total daily anthropogenic fine particulate matter emissions for the continental United States. Analysis of measured and modeled PM2.5 surface-level concentrations suggests that the transport of particulate matter pollution associated with the fires resulted in a 24 - 42 % enhancement in median surface-level PM2.5 concentrations across the eastern United States during 19 - 23 July 2004.

AN - 69536732; 18691642 AB - The issue as to whether natural and man-made chemicals interfere with endocrine function has raised concerns. This interference could be biologically significant even at very low doses if the chemicals interact deleteriously with hormone receptors at low concentrations. Therefore, the United States Environmental Protection Agency (USEPA) Office of Coordination and Policy (OSCP) requested that a nonhuman mammalian androgen receptor binding assay be developed for possible use in their Endocrine Disruptor Screening Program (EDSP). Ideally, this assay would be high throughput, not use animals as a source of receptor protein, easily deployed throughout the scientific community, utilize reagents available to both the public and private sector, and have the potential for future automation. We developed a highly modified 96-well plate assay which meets these criteria. It employs a baculovirus expressed recombinant primate androgen receptor which is publically available and exploits the unique ability of some mammalian androgen receptors to remain biologically active after guanidine hydrochloride (GdnHCl) solubilization. This GdnHCl treated receptor remains soluble and requires no additional purification prior to use. We provide a very detailed description of the assay protocol itself, and similarly detailed method for producing and solubilizing the receptor.

AN - 69637778; 18793396 AB - Staphylococcus aureus (S. aureus), is responsible for many infectious diseases, ranging from benign skin infections to life-threatening endocarditis and toxic shock syndrome. Ortho-phenylphenol (OPP) is an antimicrobial agent and an active ingredient of EPA-registered disinfectants with wide human exposure in various agricultural, hospital and veterinary disinfectant products. Despite many uses, an understanding of a cellular response to OPP and it's mechanism of action, targeted genes, and the connectivity between targeted genes and the rest of cell metabolism remains obscure. Herein, we performed a genome-wide transcriptome analysis of the cellular responses of S. aureus when exposed to 0.82 mM of OPP for 20 and 60 min. Our data indicated that OPP downregulated the biosynthesis of many amino acids, which are required for protein synthesis. In particular, the genes encoding the enzymes of the diaminopimelate (DAP) pathway which results in lysine biosynthesis were significantly downregualted. Intriguingly, we revealed that the transcription of genes encoding ribosomal proteins was upregulated by OPP and at the same time, the genes encoding iron acquisition and transport were downregulated. The genes encoding virulence factors were upregulated and genes encoding phospholipids were downregulated upon 20 min exposure to OPP. By using microarray analysis that enables us to simultaneously and globally examine the complete transcriptome during cellular responses, we have revealed novel information regarding the mode of action of OPP on Staphylococcus: OPP inhibits anabolism of many amino acids and highly downregulates the genes that encode the enzymes involved in the DAP pathway. Lysine and DAP are essential for building up the peptidoglycan cell wall. It was concluded that the mode of action of OPP is similar to the mechanism of action of some antibiotics. The discovery of this phenomenon provides useful information that will benefit further antimicrobial research on S. aureus.

AN - 69384397; 18579180 AB - Fish consumption rates derived from national surveys may not accurately reflect consumption rates in a particular population such as recreational anglers. Many state and local health agencies in the U.S. have conducted area-specific surveys to study fish consumption patterns in local populations, assess exposure to environmental contaminants, or evaluate compliance with fish advisories. The U.S. Environmental Protection Agency (EPA) has analyzed the raw data from fish consumption surveys in Florida, Connecticut, Minnesota, and North Dakota for the purpose of deriving distributions of fish consumption rates and studying the variables that may be more predictive of high-end consumers. Distributions of fish consumption for different age cohorts, ethnic groups, socioeconomic statuses, types of fish (i.e., freshwater, marine, estuarine), and source of fish (i.e., store-bought versus self-caught) were derived. Consumption of fish and shellfish for those who consume both caught and bought fish is higher than those who reported eating only bought or only self-caught. Mean fish consumption per kilogram of body weight ranged from 0.11 g/kg-day to 2.3 g/kg-day. The highest values were observed in Florida for children 1<6 years of age. The Florida data show a statistically significant increase in the percentage of the population reporting fish and shellfish consumption with an increase in household income and education. This trend was not observed in the other states.

While toxicokinetic differences between juveniles and adults are documented, toxicodynamic differences have not been examined. Voltage-gated sodium channels, the primary targets of pyrethroids, are comprised of a and b subunits, each of which have multiple isoforms that are expressed in a developmentally-regulated manner. To begin to test whether toxicodynamic differences could contribute to age-dependent deltamethrin toxicity, deltamethrin effects were examined on sodium currents in Xenopus laevis oocytes injected with different combinations of rat a (Na sub(v)1.2 or Na sub(v)1.3) and b (b sub(1) or b sub(3)) subunits. Deltamethrin induced tail currents in all isoform combinations and increased the percent of modified channels in a concentration-dependent manner. Effects of deltamethrin were dependent on subunit combination; Na sub(v)1.3-containing channels were modified to a greater extent than were Na sub(v)1.2-containing channels. In the presence of a b subunit, deltamethrin effects were significantly greater, an effect most pronounced for Na sub(v)1.3 channels; Na sub(v)1.3/b sub(3) channels were more sensitive to deltamethrin than Na sub(v)1.2/b sub(1) channels. Na sub(v)1.3 /b sub(3) channels are expressed embryonically, while the Na sub(v)1.2 and b sub(1) subunits predominate in adults, supporting the hypothesis for age-dependent toxicodynamic differences. Structure-activity relationships for sensitivity of these subunit combinations were examined for other pyrethroids. Permethrin and tetramethrin did not modify currents mediated by either subunit combination. Cypermethrin, b-cyfluthrin, esfenvalerate and fenpropathrin all modified sodium channel function; effects were significantly greater on Na sub(v)1.3/b sub(3) than on Na sub(v)1.2/b sub(1) channels. These data demonstrate a greater sensitivity of Na sub(v)1.3 vs Na sub(v)1.2 channels to deltamethrin and other cyano-containing pyrethroids, particularly in the presence of a b subunit.

Using a 80/20v/v toluene-acetonitrile mobile phase and a 4.6 mm x 150 mm Cosmosil 5micron PYE column, C(60), C(70), and PCBM ([6,6]-phenyl C(61)-butyric acid methyl ester) were fully resolved. Selectivity factors (alpha) for C(60) relative to PCBM and C(70) relative to C(60) were 3.18 and 2.19, respectively. The best analytical wavelengths for the fullerenes were determined to be 330, 333, and 333 nm with log molar absorption coefficients (log epsilon) of 4.63, 4.82, and 4.60 for PCBM, C(60), C(70), respectively. Extraction and quantitation of all three fullerenes in aqueous suspensions over a range of pH (4-10) and ionic strengths were very good. Whole-method quantification limits for ground and surface suspensions were 2.87, 2.48, and 6.54 microg/L for PCBM, C(60), and C(70), respectively. JF - Journal of chromatography.

AN - 69560205; 18800550 AB - Iron and sulfur reducing conditions generally develop in permeable reactive barrier systems (PRB) constructed to treat contaminated groundwater. These conditions allow formation of FeS mineral phases. FeS readily degrades TCE, but a transformation of FeS to FeS2 could dramatically slow the rate of TCE degradation in the PRB. This study uses acid volatile sulfide (AVS) and chromium reducible sulfur (CRS) as probes for FeS and FeS2 to investigate iron sulfide formation and transformation in a column study and PRB field study dealing with TCE degradation. Solid phase iron speciation shows that most of the iron is reduced and sulfur partitioning measurements show that AVS and CRS coexist in all samples, with the conversion of AVS to CRS being most significant in locations with potential oxidants available. In the column study, 54% of FeS was transformed to FeS2 after 2.4 years. In the field scale PRB, 43% was transformed after 5.2 years. Microscopy reveals FeS, Fe3S4 and FeS2 formation in the column system; however, only pyrite formation was confirmed byX-ray diffraction. The polysulfide pathway is most likely the primary mechanism of FeS transformation in the system, with S0 as an intermediate species formed through H2S oxidation.

AN - 69552421; 18722637 AB - Several sources of bacterial inocula were tested for their ability to reduce nitrate and perchlorate in synthetic ion-exchange spent brine (30-45 g/L) using a hydrogen-based membrane biofilm reactor (MBfR). Nitrate and perchlorate removal fluxes reached as high as 5.4 g Nm(-2)d(-1) and 5.0 g ClO(4)m(-2)d(-1), respectively, and these values are similar to values obtained with freshwater MBfRs. Nitrate and perchlorate removal fluxes decreased with increasing salinity. The nitrate fluxes were roughly first order in H(2) pressure, but roughly zero-order with nitrate concentration. Perchlorate reduction rates were higher with lower nitrate loadings, compared to high nitrate loadings; this is a sign of competition for H(2). Nitrate and perchlorate reduction rates depended strongly on the inoculum. An inoculum that was well acclimated (years) to nitrate and perchlorate gave markedly faster removal kinetics than cultures that were acclimated for only a few months. These results underscore that the most successful MBfR bioreduction of nitrate and perchlorate in ion-exchange brine demands a well-acclimated inoculum and sufficient hydrogen availability.

AN - 69465258; 18602129 AB - The developmental consequences of exposure to the polychlorinated biphenyls (PCBs) have been widely studied, making PCBs a unique model to understand issues related to environmental mixture of persistent chemicals. PCB exposure in humans adversely affects neurocognitive development, causes psychomotor difficulties, and contributes to attention deficits in children, all of which seem to be associated with altered patterns of neuronal connectivity. In the present study, we examined gene expression profiles in the rat nervous system following PCB developmental exposure. Pregnant rats (Long-Evans) were dosed perinatally with 0 or 6 mg/kg/day of Aroclor 1254 from gestation day 6 through postnatal day (PND) 21. Gene expression in cerebellum and hippocampus from PND7 and PND14 animals was analyzed with an emphasis on developmental aspects. Changes in gene expression (> or =1.5 fold) in control animals identified normal developmental changes. These basal levels of expression were compared to data from Aroclor 1254-treated animals to determine the impact of gestational PCB exposure on developmental parameters. The results indicate that the expression of a number of developmental genes related to cell cycle, synaptic function, cell maintenance, and neurogenesis is significantly altered from PND7 to PND14. Aroclor 1254 treatment appears to dampen the overall growth-related gene expression levels in both regions with the effect being more pronounced in the cerebellum. Functional analysis suggests that Aroclor 1254 delays maturation of the developing nervous system, with the consequences dependent on the ontological state of the brain area and the functional role of the individual gene. Such changes may underlie learning and memory deficits observed in PCB exposed animals and humans.

AN - 69432015; 18535856 AB - As land use continues to alter riparian areas, historical information is increasingly needed to help establish reference conditions for monitoring and assessment. I developed and applied a procedure in the John Day and Deschutes river basins of eastern Oregon for synthesizing historical documentary records available across broad spatial areas to reconstruct 19th-century riparian conditions. The study area was stratified by ecoregion and stream physical characteristics to partition regional variability. Three primary data sources-General Land Office survey notes, historical photographs, and written accounts-provided descriptive records, which were grouped by topic to develop common riparian attributes. The number of records for each attribute was tallied by stratum to compare and contrast riparian structure and composition across strata and ecoregions. Detailed descriptions of historical riparian conditions using the original documentary records further illustrated the unique riparian conditions in each stratum. Similarities and differences in historical riparian structure and composition at the stratum and ecoregion levels were evident based on the distributional pattern and numbers of records of attributes across strata. A high number of repeated observations within and among primary data sources helped to corroborate descriptive data. Although these reference data cannot provide the detail needed for rigorous quantitative assessments, they do describe a range of conditions approaching a minimally disturbed condition and provide an important perspective for conducting riparian assessments in highly disturbed regions where least-disturbed reference sites are often poor examples of a desired condition.

AN - 69409690; 18689738 AB - Forty-six broad-scale landscape metrics derived from commonly used landscape metrics were used to develop potential indicators of total phosphorus (TP) concentration, total ammonia (TA) concentration, and Escherichia coli bacteria count among 244 sub-watersheds of the Upper White River (Ozark Mountains, USA). Indicator models were developed by correlating field-based water quality measurements and contemporaneous remote-sensing-based ecological metrics using partial least squares (PLS) analyses. The TP PLS model resulted in one significant factor explaining 91% of the variability in surface water TP concentrations. Among the 18 contributing landscape model variables for the TP PLS model, the proportions of a sub-watershed that are barren and in human use were key indicators of water chemistry in the associated sub-watersheds. The increased presence and reduced fragmentation of forested areas are negatively correlated with TP concentrations in associated sub-watersheds, particularly within close proximity to rivers and streams. The TA PLS model resulted in one significant factor explaining 93% of the variability in surface water TA concentrations. The eight contributing landscape model variables for the TA PLS model were among the same forest and urban metrics for the TP model, with a similar spatial gradient trend in relationship to distance from streams and rivers within a sub-watershed. The E. coli PLS model resulted in two significant factors explaining 99.7% of the variability in E. coli cell count. The 17 contributing landscape model variables for the E. coli PLS model were similar to the TP and TA models. The integration of model results demonstrates that forest, riparian, and urban attributes of sub-watersheds affect all three models. The results provide watershed managers in the Ozark Mountains with a broad-scale vulnerability prediction tool, focusing on TP, TA, and E. coli, and are being used to prioritize and evaluate monitoring and restoration efforts in the vicinity of the White River, a major tributary to the Mississippi River and Gulf of Mexico.

AN - 69408350; 18433838 AB - Numerous studies have shown that a variety of manufactured and natural organic compounds such as pharmaceuticals, steroids, surfactants, flame retardants, fragrances, plasticizers and other chemicals often associated with wastewaters have been detected in the vicinity of municipal wastewater discharges and livestock agricultural facilities. To provide new data and insights about the environmental presence of some of these chemicals in untreated sources of drinking water in the United States targeted sites were sampled and analyzed for 100 analytes with sub-parts per billion detection capabilities. The sites included 25 ground- and 49 surface-water sources of drinking water serving populations ranging from one family to over 8 million people. Sixty-three of the 100 targeted chemicals were detected in at least one water sample. Interestingly, in spite of the low detection levels 60% of the 36 pharmaceuticals (including prescription drugs and antibiotics) analyzed were not detected in any water sample. The five most frequently detected chemicals targeted in surface water were: cholesterol (59%, natural sterol), metolachlor (53%, herbicide), cotinine (51%, nicotine metabolite), beta-sitosterol (37%, natural plant sterol), and 1,7-dimethylxanthine (27%, caffeine metabolite); and in ground water: tetrachloroethylene (24%, solvent), carbamazepine (20%, pharmaceutical), bisphenol-A (20%, plasticizer), 1,7-dimethylxanthine (16%, caffeine metabolite), and tri (2-chloroethyl) phosphate (12%, fire retardant). A median of 4 compounds were detected per site indicating that the targeted chemicals generally occur in mixtures (commonly near detection levels) in the environment and likely originate from a variety of animal and human uses and waste sources. These data will help prioritize and determine the need, if any, for future occurrence, fate and transport, and health-effects research for subsets of these chemicals and their degradates most likely to be found in water resources used for drinking water in the United States.

AN - 69404478; 18511431 AB - Perfluorobutyrate (PFBA) is a perfluoroalkyl acid (PFAA) found in the environment. Previous studies have indicated developmental toxicity of PFAAs (perfluorooctane sulfonate [PFOS] and perfluorooctanoate [PFOA]); the current study examines that of PFBA. PFBA/NH4(+) was given to timed-pregnant CD-1 mice by oral gavage daily from gestational day (GD) 1 to 17 at 35, 175, or 350 mg/kg (chosen to approximate the developmentally toxic doses of PFOA); controls received water. At GD 18, serum levels of PFBA were 3.8, 4.4, and 2.5 microg/ml, respectively, in the three treated groups. PFBA did not significantly affect maternal weight gain, number of implantations, fetal viability, fetus weight, or incidence of fetal malformations. Incidence of full-litter loss was significantly greater in the 350 mg/kg group, and maternal liver weights were significantly increased in the 175 and 350 mg/kg groups. In contrast to PFOA and PFOS, PFBA exposure during pregnancy did not adversely affect neonatal survival or postnatal growth. Liver enlargement was detected in the PFBA-exposed pups on postnatal day (PD) 1, but not by PD 10. Expression of selected hepatic genes in PFBA-exposed pups at PD 1 did not reveal any significant changes from controls. A significant delay in eye-opening in offspring was detected in all three PFBA groups, and slight delays in the onset of puberty were noted in the 175 and 350 mg/kg groups. These data suggest that exposure to PFBA during pregnancy in the mouse did not produce developmental toxicity comparable to that observed with PFOA, in part, due to rapid elimination of the chemical.

AN - 69402615; 18539913 AB - Identification of chemicals that pose a hazard to the developing nervous system is the first step in reducing human exposure and preventing health risks to infants and children. In response to the need for more efficient methods to identify potential developmental neurotoxicants, the present study evaluated the utility of an automated high content screening system to detect chemical effects on neurite outgrowth in Neuroscreen-1 cells (NS-1), a subclone of PC12 cells. Plating 2000 NS-1 cells per well with 100 ng/ml nerve growth factor for 96 h produced optimal neurite growth in a 96-well format. Using this protocol, five chemicals that had been previously shown to inhibit neurite outgrowth in PC12 cells were examined. Inhibition of neurite outgrowth (assessed as total neurite length per cell) was observed for all five chemicals. For three of the chemicals, inhibition was associated with decreased cell viability. To demonstrate the utility of this approach for screening, a further set of chemicals (eight known in vivo developmental neurotoxicants and eight chemicals with little evidence of in vivo neurotoxicity) were tested over a wide concentration range (1 nM-100 microM). Trans-retinoic acid, dexamethasone, cadmium, and methylmercury inhibited neurite outgrowth, although dexamethasone and cadmium only affected neurite outgrowth at concentrations that decreased viability. Amphetamine facilitated neurite outgrowth, whereas valproic acid, diphenylhydantoin, and lead had no effect. Of the chemicals that were not neurotoxic, there were no effects on cell viability, but two (dimethyl phthalate and omeprazole) increased neurite outgrowth at the highest concentration tested. These results demonstrate that a high content screening system can rapidly quantify chemical effects on neurite outgrowth in vitro. Concentration-response data for both neurite outgrowth and cell viability allowed for the determination of the specificity of chemical effects on a neurodevelopmental endpoint.

AN - 69402342; 18411233 AB - Phthalate diesters are chemicals to which humans are ubiquitously exposed. Exposure to certain phthalates during sexual differentiation causes reproductive tract malformations in male rats. In the fetal rat, exposure to the phthalates benzylbutyl phthalate (BBP), di(n)butyl phthalate (DBP), and diethylhexyl phthalate (DEHP) decreases testicular testosterone production and insulin-like 3 hormone mRNA levels. We characterized the dose-response effects of six individual phthalates (BBP, DBP, DEHP, diethyl phthalate [DEP], diisobutyl phthalate [DiBP], and dipentyl phthalate [DPP]) on gestation day (GD) 18 testicular testosterone production following exposure of Sprague-Dawley rats on GD 8-18. BBP, DBP, DEHP, and DiBP were equipotent (ED50 of 440 +/- 16 mg/kg/day), DPP was about threefold more potent (ED50 = 130 mg/kg/day) and DEP had no effect on fetal testosterone production. We hypothesized that coadministration of these five antiandrogenic phthalates would reduce testosterone production in a dose-additive fashion because they act via a common mode of toxicity. In a second study, dams were dosed at 100, 80, 60, 40, 20, 10, 5, or 0% of the mixture. The top dose contained 1300 mg of total phthalates/kg/day including BBP, DBP, DEHP, DiBP (300 mg/kg/day per chemical), and DPP (100 mg DPP/kg/day). This mixture ratio was selected such that each phthalate would contribute equally to the reduction in testosterone. As hypothesized, testosterone production was reduced in a dose-additive manner. Several of the individual phthalates and the mixture also induced fetal mortality, due to pregnancy loss. These data demonstrate that individual phthalates with a similar mechanism of action can elicit cumulative, dose additive effects on fetal testosterone production and pregnancy when administered as a mixture.

Sorption of arsenate (As(V)) and arsenite (As(III)) on magnetite is an important process of arsenic removal from groundwater using zerovalent iron-based permeable reactive barrier (PRB) technology and natural attenuation. We tested eight magnetite samples (one from Phoenix Environmental Ltd, one from Cerac, Inc. and six from Connelly-GPM, Inc.) that contained from 79 to 100% magnetite. The magnetites were reacted in the absence of light with either As(V) or As(III) in 0.01M NaCl at 23C at equilibrium pH 2.5-11.5 for 24h. As(V) sorption showed a continuous drop with increasing pH from 2.5 to 11.5; whereas, As(III) sorption exhibited maxima from pH 7 to 9. Equal amounts of As(V) and As(III) were sorbed at pH 5.6-6.8. Higher amounts of As(III) were sorbed by the magnetites than As(V) at pH values greater than 6.8. The solution speciation test did not show any chemical reduction of As(V) in any magnetite suspension, which is consistent with the X-ray Photoelectron Spectroscopy (XPS) study of a Connelly-GPM magnetite (CC-1048) suspension. Conversely, XPS results show that the As(III) is partially oxidized in the magnetite (CC-1048) suspension. This is also consistent with the batch test results that also show more oxidation occurring at alkaline pH. Complete oxidation of As(III) occurred in a synthetic birnessite (d-MnO sub(2)) suspension after 24h of reaction. The minute impurities of Mn (possibly as an oxide form) in the magnetite samples may have been responsible for As(III) oxidation. In addition, the structural Fe(III) in magnetite and hydroxyl radicals in solution could also serve as oxidants for As(III) oxidation. The conversion of As(III) to As(V) in the magnetite suspensions would be beneficial in a remediation scheme for As removal, since As(V) is considered less toxic than As(III). Information from the present study can help predict the sorption behavior and fate of arsenic species in engineered PRB systems and natural environments.

We therefore examined how the factors of impervious extent, connectivity, and antecedent moisture content of pervious areas might affect mechanisms of runoff production at small spatial scales in a laboratory setting. We used rainfall simulation (with a storm comprised of 20, 30, 40 mm hr super(-1) rainfall rates for 48, 24, and 24 min, respectively) to observe surface runoff from 0.6 m super(2) boxes (impervious or pervious-soil) 0.2 m deep that were connected together in series to produce different arrangements of impervious and pervious surfaces (0, 25, 50% impervious) with different connectivity to the outlet (disconnected, connected), and under two different antecedent moisture conditions for pervious areas (drier, wetter). In general, an increase in percent impervious area led to fewer opportunities for infiltration, and a quicker onset of runoff, which was intensified by wetter antecedent moisture conditions and connectivity to the outlet. Runoff rate ratios were strongly affected by antecedent moisture condition and somewhat less significantly by an interaction between impervious area extent and its connectivity status. In each impervious treatment, we observed a decreased time to runoff initiation and higher final runoff rate ratio for wetter than drier treatments. Interestingly, we found that the connectivity of 25% impervious area accounted for differences in runoff rate ratio only early in the simulation. The patterns in runoff from connected and disconnected 25% treatments eventually converged, leaving antecedent moisture conditions the only relevant factor. As impervious area was increased to 50%, we noted a precipitous decline in infiltration rates due to a reduction in infiltration opportunities and infiltration behavior of the pervious surfaces in these treatments. Evidence of return flow in the 50% disconnected treatment is presented and discussed in the context of saturation-excess runoff mechanisms. These experimental results are then discussed in terms of their potential extension and application to better understand aspects of urban hydrology and models thereof.

Propiconazole is a mouse liver hepatotoxicant and a hepatocarcinogen that has adverse reproductive and developmental toxicities in experimental animals. The goal of this study was to investigate the cytotoxic responses of propiconazole and its metabolites to determine if metabolism of this agent differentially affected its cytotoxic activities in hepatic tumor cell lines and in primary hepatocytes. To this end the cytotoxic effects of propiconazole and five of its metabolites were examined in three hepatic cell types: The mouse hepatoma Hepa1c1c7 cell line, the human hepatoma HepG2 cell line, and primary cultures of mouse hepatocytes. We initially compared the responses of propiconazole exposure in both Hepa1c1c7 and HepG2 cell lines over a concentration range of 0-200kM using two assay systems: The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and the neutral red assay. Concentration-related cytotoxic responses were evident in both cell lines using both endpoints with the MTT assay providing enhanced sensitivity. The relative cytotoxic effects of propiconazole and five propiconazole metabolites were further assessed by the MTT assay using Hepa1c1c7 and HepG2 tumor cell lines. The cell cultures were exposed to various concentrations of propiconazole and five of its metabolites over a range of 0-400kM. Propiconazole was cytotoxic in both cell lines in a dose-dependent manner. All five metabolites were less cytotoxic in both cell lines compared to the parent compound. The most cytotoxic metabolites in Hepa1c1c7 and HepG2 cells among the five were 3-(2-((1H-1,2,4-triazol-1-yl)methyl)-2-(2,4-dichlorophenyl)-1,3-di o xolan-4-yl)propan-1-ol and 1-(2-((1H-1,2,4-triazol-1-yl)methyl)-2-(2,4-dichlorophenyl)-1,3-di o xolan-4-yl)propan-2-ol. Propiconazole was cytotoxic in primary mouse hepatocytes; however none of the five propiconazole metabolites exerted cytotoxic activities. There was a linear relationship between the cLogP and the cytotoxic effects of propiconazole and its five metabolites in Hepa1c1c7 cells. We conclude that these propiconazole metabolites would not contribute to the propiconazole-induced cytotoxicity process in primary mouse hepatocytes. Furthermore, since in tumor cell lines the metabolites were less cytotoxic than the parent propiconazole, our results suggest that in the tumorigenesis process as tumor cells are formed they would be more susceptible to the cytotoxic effects of propiconazole compared to the metabolites. coefficient) JF - Toxicology In Vitro AU - Chen, P J AU - Moore, T AU - Nesnow, S AD - National Health and Environmental Effects Research Laboratory, US Environmental Protection Agency, B143-06, 109 T.W.

Although several chemicals are assessed annually under the current developmental neurotoxicity guidelines, time, resource, and animal constraints prevent testing of large numbers of chemicals using this approach. Thus, incentive is mounting to develop in vitro methods to screen chemicals for their potential to harm the developing human nervous system. As an initial step toward this end, the present studies evaluated an automated, high-throughput method for screening chemical effects on proliferation and viability using ReNcell CX cells, a human neural progenitor cell (hNPC) line. ReNcell CX cells doubled in 636 h and expressed the neural progenitor markers nestin and SOX2. High-throughput assays for cell proliferation (5-bromo-2'-deoxyuridine incorporation) and viability (propidium iodide exclusion) were optimized and tested using known antiproliferative compounds. The utility of this in vitro screen was evaluated further using a set of compounds containing eight known to cause developmental neurotoxicity and eight presumably nontoxic compounds. Six out of eight developmental neurotoxicants significantly inhibited ReNcell CX cell proliferation and/or viability, whereas two out of eight nontoxic chemicals caused only minimal effects. These results demonstrate that chemical effects on cell proliferation and viability can be assessed via high-throughput methods using hNPCs. Further development of this approach as part of a strategy to screen compounds for potential effects on nervous system development is warranted.

We addressed two issues, which arise when attempting to detect differences between benthic communities. The first is the varying sensitivity of metrics, e.g. one metric may not be able to detect differences between two communities where another metric can. The second is the influence of season on the detection of differences between benthic communities from different estuarine systems. In this study, benthic communities taken from depositional sites were sampled in three seasons, at three sites within two relatively pristine estuaries located in southern Massachusetts, USA. Statistical comparisons of benthic community data from the two estuaries were made using three common metrics: species richness, Shannon diversity and Bray-Curtis similarity indices. Significant community differences were found depending upon the index. The Bray-Curtis index, using permutation testing, was the only metric that detected differences between estuaries despite disparate seasonal sampling. This suggests that researchers do not need to be overly constrained to sampling in the same season when testing for differences in benthic communities between estuaries. Additionally, we propose an analytical method to identify anthropogenically impacted estuarine systems.

These control scenarios are simulated with photochemical models, which use emissions and meteorological variables to simulate PM2.5 formation, transport, and deposition. A monitor study was established in the central United States to measure simultaneously the PM2.5 sulfate ion, nitrate ion, ammonium ion, and chemical precursor species sulfur dioxide, nitric acid, and ammonia during 2004. These data, combined with nearby meteorological observations, provide an opportunity to assess whether meteorological variables or deposition processes may introduce systematic biases in PM2.5 ammonium sulfate and ammonium nitrate predictions. Skill in estimating total wet deposition is assessed by comparing model output with National Atmospheric Deposition Program monitors in the region. Meteorological variables that are important for mass transport (wind vector) and thermodynamic chemistry (temperature and relative humidity) compare well to observations. A model sensitivity, in which the temperatures in the inorganic chemistry module are adjusted to compensate for an underprediction bias, shows a minimal model response in predicted PM2.5 ammonium nitrate. The dry deposition of sulfur dioxide seems to have a systematic impact on ambient estimates of sulfur dioxide in the photochemical model. An attempt to correlate bias and error in meteorological variables to bias and error in PM2.5 species showed the most relationship between relative humidity and temperature and ammonium nitraite. Wet deposition of total sulfate, nitrate, and ammonium tend to be underpredicted in the winter months.

A process integrating steam stripping with a vapor compression step and a vapor permeation membrane separation step is proposed. The objective of this work is to estimate the energy and process costs required to make a fuel grade ethanol (0.5 wt% water) from 1 and 5 wt% ethanol aqueous streams using the proposed process. Using process simulation and spreadsheeting software, the proposed membrane-assisted vapor stripping process was estimated to require as little as 8.9 MJ of fuel-equivalent energy per kg of fuel grade ethanol recovered from a 1 wt% ethanol feed stream, 2.5 MJ kg-1 for a 5 wt% ethanol solution. This represents an energy saving of at least 43% relative to standard distillation producing azeotropic ethanol (6 wt% water). Process costs were also found to be lower than for distillation at the 3.0 X 106 kg-ethanol year-1 scale modeled. In this hybrid system, the stripping column provides high ethanol recoveries and low effluent concentrations while the vapor compression-membrane component enables the efficient recovery of latent and sensible heat from both the retentate and permeate streams from the membrane system.

Assuming a uniform 10% decline in ambient PM levels, the preventible cases of: (1) premature mortality ranged from 35 in Houston to 379 in Seoul, (2) chronic bronchitis ranged from 95 in Houston to 1,631 in Seoul, (3) cardiovascular disease ranged from 68 in Houston to 818 in Seoul, (4) pneumonia ranged from 28 in Houston to 336 in Seoul, (5) asthma attacks ranged from 388 in Osaka to 96,876 in Seoul, and (6) acute bronchitis ranged from 186 in Houston to 2,973 in Seoul. The per million population central estimate of the purchasing power parity adjusted value of health and productivity benefits ranged from $25 million in Bangkok to $160 million in Osaka. There was a wide variability in measured PM sub(10) levels across cities. Percentages of active monitors reporting concentrations above 50, mu g/m super(3) (annual average) or 150 mu g/m super(3) (24-hour average) in 2001-2002 were 0% in Houston, 5% in Osaka, 33% in Bangkok and 92% in Seoul. Assuming a non-uniform reduction in PM only at concentration hotspots with levels above air quality standards, the number of preventible cases of mortality ranged from 0 in Houston to 1,104 in Seoul. The central estimate of total benefits ranged from $0 in Houston to $240 million in Seoul.

Rapid field-based indicators of hydrologic permanence are needed for making jurisdictional determinations. Our study objectives were to: 1) identify physical characteristics of forested headwater streams that best distinguish perennial, intermittent, and ephemeral reaches and 2) assess the applicability of existing rapid field-based tools for classifying hydrologic permanence across a wide geographic range. We surveyed reach- and drainage-scale characteristics at 113 sites across 10 study forests in the US. Streams in 4 core forests (61 core sites) were sampled over 2 consecutive years and were used in model construction. Streams in 6 satellite forests (72 satellite sites) were used to validate the models over a broader geographic range. Discriminant function models successfully differentiated hydrologic permanence categories at core sites. Drainage area, the Ohio Environmental Protection Agency Headwater Habitat Evaluation Index (HHEI), and the North Carolina Department of Water Quality Stream Classification Method (NCSC) were strongly correlated with the discriminant function that separated ephemeral from perennial and intermittent sites. Entrenchment ratio was the most consistent variable discriminating intermittent from perennial sites across the core forests. The models had mixed results when applied to the validation data set, but did classify correctly most intermittent and ephemeral sites. Classification trees were used to assess broad regional applicability of existing rapid field-based protocols and to identify important metrics. Scores from the Rapid Bioassessment Protocol Habitat Assessment, HHEI, and NCSC all clearly distinguished ephemeral from intermittent and perennial sites, but no differences were detected between intermittent and perennial sites across all sites. However, data from core sites do indicate that a suite of physical variables can be used successfully to identify hydrologic permanence at regional scales.

Participants were randomly recruited from six NC and six OH counties. Monitoring was performed over a 48-h period at the participants' homes. Environmental samples included soil, outdoor air, indoor air, and carpet dust. Personal samples collected by the adult caregivers concerning themselves and their children consisted of solid food, liquid food, hand wipe, and spot urine samples. All samples were analyzed for 2,4-D (free acid form) by gas chromatography/mass spectrometry. 2,4-D was detected in all types of environmental samples but most often in carpet dust samples, with detection frequencies of 83% and 98% in NC and OH, respectively. The median level of 2,4-D in the carpet dust samples was about three times higher in OH homes compared to NC homes (156 vs. 47.5 ng/g, P48%) than from NC participants (<9%). Hand wipe levels at the 95th percentile were about five times higher for OH children (0.1 ng/cm super(2)) and adults (0.03 ng/cm super(2)) than far the NC children (0.02 ng/cm super(2)) and adults (<0.005 ng/cm super(2)). 2,4-D was detected in more than 85% of the child and adult urine samples in both states. The median urinary 2,4-D concentration was more than twice as high for OH children compared to NC children (1.2 vs. 0.5 ng/ml, P<0.0001); however, the median concentration was identical at 0.7 ng/ml for both NC and OH adults. The intraclass correlation coefficient of reliability for an individual's urinary 2,4-D measurements, estimated from the unadjusted (0.31-0.62) and specific gravity-adjusted (0.37-0.73) values, were somewhat low for each group in this study. The variability in urinary 2,4-D measurements over the 48-h period for both children and adults in NC and OH suggests that several spot samples were needed to adequately assess these participants' exposures to 2,4-D in residential settings. Results from this study showed that children and their adult caregivers in NC and OH were likely exposed to 2,4-D through several pathways at their homes. In addition, our findings suggest that the OH children might have been exposed to higher levels of 2,4-D through the dermal and nondietary routes of exposure than the NC children and the NC and OH adults.

We characterized macroinvertebrate communities from riffles in 37 small West Virginia streams (10 unmined and 27 mined sites with valley fills) sampled in the spring index period (March-May) and compared the assessment results using family- and genus-level taxonomic data. Specific conductance was used to categorize levels of mining disturbance in mined watersheds as low (1000 kS/cm). Four lines of evidence indicate that mining activities impair biological condition of streams: shift in species assemblages, loss of Ephemeroptera taxa, changes in individual metrics and indices, and differences in water chemistry. Results were consistent whether family- or genus-level data were used. In both family- and genus-level nonmetric multidimensional scaling (NMS) ordinations, mined sites were significantly separated from unmined sites, indicating that shifts in community structure were caused by mining. Several Ephemeroptera genera (e.g., Ephemerella, Epeorus, Drunella) and their families (Ephemerellidae, Heptageniidae) were correlated most strongly with the primary NMS axis (r > 0.59 for these genera; r > 0.78 for these families). These same Ephemeroptera were absent and, thus, eliminated from most of the mined sites. Total Ephemeroptera richness and relative abundance both declined with increasing mining disturbance. Several other metrics, such as richness, composition, tolerance, and diversity, clearly discriminated unmined vs mined sites. Most family-level metrics performed well and approximated the strength of genus-based metrics. A genus-based multimetric index (MMI) rated more mined sites as impaired than did the family-based MMI. Water-quality variables related to mining were more strongly correlated to NMS axis-1 scores, metrics, and MMIs than were sedimentation and riparian habitat scores. Generally, the correlations between the genus-level MMI and water-quality variables were stronger than the correlations between the family-level MMI and those variables. Our results show that mining activity has had subtle to severe impacts on benthic macroinvertebrate communities and that the biological condition most strongly correlates with a gradient of ionic strength.

In this paper, a Bayesian method for evaluating this component of a total maximum daily load (TMDL) load capacity is developed and applied. The joint distribution of nutrient retention metrics from a literature review of 495 measurements was used for Monte Carlo sampling with a process transfer function for nutrient attenuation. Using the resulting histograms of nutrient retention, reference prior distributions were developed for sites in which some of the metrics contributing to the transfer function were measured. Contributing metrics for the prior include stream discharge, cross-sectional area, fraction of storage volume to free stream volume, denitrification rate constant, storage zone mass transfer rate, dispersion coefficient, and others. Confidence of compliance (CC) that any given level of nutrient retention has been achieved is also determined using this approach. The shape of the CC curve is dependent on the metrics measured and serves in part as a measure of the information provided by the metrics to predict nutrient retention. It is also a direct measurement, with a margin of safety, of the fraction of export load that can be reduced through changing retention metrics. For an impaired stream in western Oklahoma, a combination of prior information and measurement of nutrient attenuation was used to illustrate the proposed approach. This method may be considered for TMDL implementation.

The decisions suggest that hydrological permanence of non-navigable streams and adjacent wetlands (NNSAWs) and their effects on the chemical, physical, and biological integrity of navigable waters ("significant nexus") are relevant in determining CWA jurisdiction. This has increased the need for scientific information to support regulatory determinations and to inform future policies, rule making, and legislation. Here, we propose an approach for addressing these science needs. We define a metric - maximum duration of continuous flow - to assess hydrological permanence. We also define two metrics to evaluate significant nexus: proportion of total benefit to the navigable water contributed by an NNSAW class, and proportion of time that a navigable water receives benefit from an NNSAW. These metrics could be useful in implementing the Court's new legal standards.

Data from these personal measurements were then compared to community-based measures that might typically represent surrogate measurements of exposure often used in epidemiological assessments. To determine personal exposures to various particulate matter (PM) size fractions, a recently evaluated personal PM monitor capable of direct PM sub(1) sub(0) sub(-) sub(2) sub(.) sub(5) size fraction collection was used. Participants living in the central region of North Carolina and enrolled in the NCAAES were asked to wear the monitor attached to a supporting backpack for 24-h collection periods. These volunteers were monitored for 2 to 4days with subsequent gravimetric analysis of their PM samples. Personal PM sub(1) sub(0) sub(-) sub(2) sub(.) sub(5) mass concentrations were observed to be highly variable and ranged from 7.6 to 40.2 mu g/m super(3) over an 8-month period. The median for this measurement from all participants (50th percentile) was 13.7 mu g /m super(3). A coefficient of determination (r super(2)) of 0.02 was established for community-based PM sub(1) sub(0) sub(-) sub(2) sub(.) sub(5) mass concentrations versus personal exposures.

We describe 11 polymorphic microsatellite loci for this species. Preliminary analyses indicate that population substructure may contribute to departures from Hardy-Weinberg equilibrium. In addition, new loci failed to consistently amplify Cordylophora samples known to be genetically distant from those utilized in this study, indicating the presence of cryptic diversity within the taxon.

More specifically, we apportioned the organic fraction of the winter and summer season PM sub(2) sub(.) sub(5) using two source-receptor models - the EPA Chemical Mass Balance 8.2 (CMB) and EPA Positive Matrix Factorization 1.1 (PMF) models - and tested several case scenarios with each model by varying either the chemical species or source profiles used as model input. Moreover, we added the constraint of selecting only individual molecular marker species with concentrations above their minimum quantitative limits. Model results suggest that the molecular marker and source profile selection can strongly affect the model, as reflected in the source contribution estimates determined by both CMB and PMF. Biomass burning and mobile emissions sources were identified by both models as being major source contributors in Pittsburgh. A third source was consistent with a meat cooking profile but was more likely a combination of cooking and secondary organic aerosol. As expected, the relative proportion of each source's contribution depended on both the season and on whether the CMB or PMF model was applied. Selecting fewer species in CMB resulted in less mass being apportioned, and an unrealistically large wood burning contribution estimate. Swapping a wildfire profile for one of the two wood burning profiles also resulted in less mass being apportioned in the winter. The results suggest that CMB can distinguish between fireplace burning and wildfire contributions when appropriate species are included. The gasoline/diesel split also varied by up to an order of magnitude, depending on which model was applied and which species were fit.

In animal models, perturbations in calcium signaling, neurotransmitters, and thyroid hormones have been postulated as potential mechanisms for PCB-induced developmental neurotoxicity. In order to understand the role of these proposed mechanisms and to identify other mechanisms in PCB-induced neurotoxicity, we have chosen a global approach utilizing oligonucleotide microarrays to examine gene expression profiles in the brain following developmental exposure to Aroclor 1254 (0 or 6 mg/kg/day from gestation day 6 through postnatal day (PND) 21) in Long-Evans rats. Gene expression levels in the cerebellum and hippocampus from PNDs 7 and 14 animals were determined on Affymetrix rat 230A_2.0 chips. In the cerebellum, 87 transcripts were altered at PND7 compared to 27 transcripts at PND14 by Aroclor 1254 exposure, with only one transcript affected at both ages. In hippocampus, 175 transcripts and 50 transcripts were altered at PND7 and PND14, respectively, by Aroclor 1254 exposure with five genes commonly affected. Functional analysis suggests that pathways related to calcium homeostasis (Gng3, Ryr2, Trdn, Cacna1a), intracellular signaling (Camk2d, Stk17b, Pacsin2, Ryr2, Trio, Fert2, Ptk2b), axonal guidance (Lum, Mxd3, Akap11, Gucy1b3), aryl hydrocarbon receptor signaling (Nfia, Col1a2), and transcripts involved in cell proliferation (Gspt2, Cdkn1c, Ptk2b) and differentiation (Ifitm31, Hpca, Zfp260, Igsf4a, Hes5) leading to the development of nervous system were significantly altered by Aroclor 1254 exposure. Of the two brain regions examined, Aroclor 1254-induced genomic changes were greater in the hippocampus than the cerebellum. The genomic data suggests that PCB-induced neurotoxic effects were due to disruption of normal ontogenetic pattern of nervous system growth and development by altering intracellular signaling pathways but not by endocrine disruption.

It has since gone unreported in the Mississippi River system possibly due in part to its phenotypic variability and close morphological resemblance to the more commonly occurring zebra mussel (Dreissena polymorpha). Sampling of the upper Mississippi River system during 2004-2006 revealed that the quagga mussel occurred at several localities outside its previously reported distribution in the Ohio River and upper Mississippi River. Few zebra and no quagga mussels were found in the Missouri River. Quagga mussels were not abundant in our survey, comprising less than 1% of identifiable Dreissena specimens.

We describe here the application of the cat-SAR (categorical-SAR) program to two learning sets of rat mammary carcinogens. One set of developed models was based on a comparison of rat mammary carcinogens to rat noncarcinogens (MC-NC), and the second set compared rat mammary carcinogens to rat nonmammary carcinogens (MC-NMC). On the basis of a leave-one-out validation, the best rat MC-NC model achieved a concordance between experimental and predicted values of 84%, a sensitivity of 79%, and a specificity of 89%. Likewise, the best rat MC-MNC model achieved a concordance of 78%, a sensitivity of 82%, and a specificity of 74%. The MC-NMC model was based on a learning set that contained carcinogens in both the active (i.e., mammary carcinogens) and the inactive (i.e., carcinogens to sites other than the mammary gland) categories and was able to distinguish between these different types of carcinogens (i.e., tissue specific), not simply between carcinogens and noncarcinogens. On the basis of a structural comparison between this model and one for Salmonella mutagens, there was, as expected, a significant relationship between the two phenomena since a high proportion of breast carcinogens are Salmonella mutagens. However, when analyzing the specific structural features derived from the MC-NC learning set, a dichotomy was observed between fragments associated with mammary carcinogenesis and mutagenicity and others that were associated with estrogenic activity. Overall, these findings suggest that the MC-NC and MC-NMC models are able to identify structural attributes that may in part address the question of 'why do some carcinogens cause breast cancer', which is a different question than 'why do some chemicals cause cancer'.

Rate constants were calculated for the reactions of carbon degradation, PCDD/F formation, desorption, and degradation. For the first time, values for activation and thermodynamic parameters for the overall reactions have been calculated for PCDD/F formation, desorption, and destruction reactions. Good agreement was found between the calculated rate constants for carbon degradation and for PCDD/F formation, indicating that the two processes have a common rate-determining step. Moreover, PCDD/F formation was found to be still active after long reaction times (24 h). These results points out the importance of carbon deposits in the postcombustion stages that can account for emissions long after their formation (memory effects). The calculated formation rates were 7-15 times higher than those reported in the literature from fly ash-only experiments, indicating the importance of both soot and a continuous source of chlorine. A comparison between full-scale incinerator rates and model calculated rates indicates that our model based on carbon degradation kinetic can be a tool to estimate emissions.

AN - 69384200; 18653193 AB - A direct injection, liquid chromatography tandem mass spectrometry (LC-MS/MS) method has been developed for the analysis of the chloro-s-triazine herbicides and their degradates in finished drinking water. The target compounds in the method were selected based on their inclusion in a common mechanism group (CMG) because of their ability to induce a similar toxic effect through a common mechanism of toxicity. The target list includes the chloro-s-triazines (atrazine, simazine, cyanazine, and propazine) and their dealkylated degradates (desethylatrazine, desisopropylatrazine, and diaminochlorotriazine). Potential matrix effects are minimized by the use of individual isotopically enriched internal standards. Analyte stability in finished chlorinated drinking water samples is ensured through careful selection of proper dechlorinating and antimicrobial reagents and through buffering sample pH. In the absence of proper dechlorination, the target analytes were found to degrade over a short period of time, even under refrigerated storage conditions. The final method has adequate sensitivity to accurately detect all target analytes at or below 0.1 microg/L and displays sufficient precision and robustness to warrant publication as EPA Method 536.

Exposure to PBDEs can be through both diet and the environment and is generally estimated by measuring PBDEs in blood, adipose tissue, muscle, or milk samples. Using rats as a model, we investigated tissue distribution of PBDEs after oral administration and evaluated a suitable matrix for body burden estimation. Male rats were administered dust or corn oil containing 8 or 6 *mg PBDEs kg-1 body wt, respectively, in the diet for 21 days (N = 4 rats per treatment), and the concentration of 15 PBDEs were measured in various tissues, plasma, and feces. PBDEs were found in all tissues, including the brain, and showed no difference in distribution patterns between treatments for most PBDEs. Tri- to hexa-BDEs comprised >80% of the total PBDEs in the adipose, brain, kidney, lung, and residual carcass, but 4. BDE-209 was the dominant congener in the liver and plasma, but was not detected in the adipose tissue or carcass. In summary, the lower brominated congeners tended to distribute equally into lipids implying both adipose tissue and plasma would be suitable matrices for biomonitoring. Plasma was the best matrix for detection of the higher brominated congeners (especially BDE-209), although on a lipid-weight basis tended to overestimate the total body burdens.

We show that different assumptions about how technology choices are made in the US electricity sector in response to a carbon charge can lead to differences in estimates of environmental, fuel market, and economy-wide impacts.

AN - 69400895; 18598045 AB - Exposure of golfers to pesticides following their application to turfgrass is of concern to regulators, turfgrass professionals, and consumers. Multipathway exposures were evaluated for golfers on turfgrass treated with chlorpyrifos and carbaryl. Air concentrations and transferable foliar residues (TFRs) were measured to assess potential respiratory and dermal exposures, respectively. At the same time, exposure to individuals simulating the play of golf was determined by dosimetry and urinary biomonitoring. Individual golfer exposure was determined in 76 rounds of golf following eight applications of chlorpyrifos and two applications of carbaryl. Estimated exposures to golfers following full course and full rate applications of chlorpyrifos and carbaryl were 19-68 times below current U.S. EPA acute reference dose (Rfd) values, indicating safe exposures under U.S. EPA hazard quotient criteria. Dermal exposure was determined to be the dominant exposure pathway to golfers, accounting for approximately 60% of the chlorpyrifos absorbed dose and 100% of the carbaryl absorbed dose. This study also provides a set of transfer factors (TFs) that may be used to determine dermal exposure of golfers to pesticides using transferable residue data.

AN - 69620518; 18694480 AB - The clinical efficacy of camptothecin (CPT), a drug specifically targeting topoisomerase I (TopoI), is under evaluation for the treatment of malignant gliomas. Due to the high unresponsiveness of these tumours to chemotherapy, it would be very important to study the signalling network that drives camptothecin outcome in this type of cancer cells. To address this issue, we had previously compared the expression profile of human U87-MG glioblastoma cells with that of a CPT-resistant counterpart, giving evidence that the development of a robust inflammatory response was the main transcriptional effect associated with CPT resistance. Here we report time-related changes and cell line specific patterns of gene expression after CPT treatment by using two p53 wild-type glioblastoma cell lines, U87-MG and DBTRG-05, with different sensitivities to TopoI inhibition. First, we demonstrated that CPT treatment brings the two cell lines to completely different outcomes: accelerated senescence in U87-MG and apoptosis in DBTRG-05 cells. Then, to understand the different susceptibility to CPT, we used oligo-microarray to identify the genes whose expression was regulated during a time-course treatment, ranging from 2 h to 72 h. The statistical analysis of microarray data by MAANOVA (MicroArray ANalysis Of VAriance) showed much less modulated genes in apoptotic DBTRG-05 cells (155) with respect to the senescent U87-MG cells (3168), where the number of down-regulated genes largely exceeded that of the up-regulated ones (80% vs. 20%). Despite this great difference, the two data-sets showed a large overlapping (60% circa) mainly due to the expression of early stress responsive genes. The use of High-Throughput GoMINER and EASE tools, for functional analysis of significantly enriched GO terms, highlighted common cellular processes and showed that U87-MG and DBTRG-05 cells shared many GO terms, which are related to the down-regulation of cell cycle and mitosis and to the up-regulation of cell growth inhibition and DNA damage.Furthermore, the down-regulation of MYC and DP1 genes, which act as key transcription factors in cell growth control, together with the inhibition of BUB1, BUB3 and MAD2 mRNAs, which are known to be involved in the spindle checkpoint pathway, were specifically associated with the execution of senescence in U87-MG cells and addressed as critical factors that could drive the choice between different CPT-inducible effectors programs. In U87-MG cells we also found inflammation response and IL1-beta induction, as late transcriptional effects of Topo I treatment but these changes were only partially involved in the senescence development, as shown by IL1-beta gene silencing. By comparing the transcription profile of two glioblastoma cell lines treated with camptothecin, we were able to identify the common cellular pathways activated upon Topo I inhibition. Moreover, our results helped in identifying some key genes whose expression seemed to be associated with the execution of senescence or apoptosis in U87-MG and DBTRG-05 cells, respectively.

AN - 20875594; 8378911 AB - This study describes the first attempt in the world to use timber poles to provide habitat connectivity for a gliding mammal. The Australian squirrel glider Petaurus norfolcensis is a small tree-dependent gliding marsupial whose habitat is characterized by ongoing fragmentation. We installed five 12m-high poles across a 70m gap that had existed between two woodland remnants for over 45 years. Our aims were to determine whether animals were able to use the poles for gliding and to travel between the remnants. We released 22 animals onto the poles at night. All animals readily climbed and glided from the poles. Five individuals successfully glided pole-to-pole on initial release. Squirrel gliders were captured in both remnants only after pole erection and two were trapped on poles. One radio-collared individual was observed gliding pole-to-pole to reach the non-home remnant where it foraged on two separate nights. Petaurus hair was detected on several poles by hair-sampling devices in four separate periods up to 12 months after radio-tracking and trapping had ceased. Our observations suggest that wooden poles may assist gliding mammals to traverse open areas between habitat patches and have the potential to be used as a rapid technique to reconnect severed habitat.

This work studied the effect of Suwannee river humic acid (SRHA) on the reduction of nitrobenzenes in goethite suspensions by Fe(II) species. The pseudo-first-order rate constant for the reduction of p-cyanonitrobenzene (kCNNB) was different for the first 3 half-lives in systems where Fe(II)aq and dissolved SRHA were equilibrated in reverse orders with goethite in suspensions. kCNNB and the reduction capacity of the system having SRHA added after Fe(II)aq was equilibrated with goethite was lower than that of the system for which the components were added in the reverse order. SRHA decreased the reduction capacity of the former system by oxidizing and/or complexing the surface-associated Fe(II), Fe(II)surf, and/or hindering the access of CNNB to Fe(II)surf. The log kCNNB increased linearly with increasing concentrations of Fe(II)aq, which decreased as a result of increasing concentrations of SRHA in the system. Different kCNNBs were observed for systems in which Fe(II)aq was equilibrated with goethite/SRHA suspensions for 24 and 48 h, suggesting sorbed SRHA oxidized and/or complexed Fe(II)aq. Findings suggest the concentration of Fe(II)aq and accessible Fe(II)surf will influence the reduction rates of nitroaromatics in anoxic environments.
