The method is based on an RP-C sub(16-Amide column and provided excellent peak resolution of most taxonomically important pigments and an elution profile different than C) sub(8) or C sub(18 columns provide. Analysis of mixed pigment standards, extracts of phytoplankton monocultures, and field samples showed that this method was able to resolve more than sixty pigments, ranging from very polar acidic chlorophylls to the non-polar hydrocarbon carotenes in less than 36 min. This included chlorophylls c) sub(1), c sub(2 and c) sub(3), divinyl chlorophylls a and b, the carotenoids lutein and zeaxanthin and some recently discovered pigments. The ability of this method to resolve divinyl chl b from monovinyl chl b and divinyl chl a from monovinyl chl a is particularly important for the quantification and identification of the marine cyanobacteria Prochlorococcus spp. in oceanic waters. The described protocol is sensitive and reproducible and can be used to assess the distribution and dynamics of major phytoplankton groups in marine and freshwater ecosystems.

One of the services most often mentioned is the retention of nutrients. I construct a simple model of agricultural land use under a regulatory requirement that nutrient loading cannot exceed a fixed ceiling. Farmers decide the quantity of residual nutrients they will generate, how much land they will allocate to production, and, consequently, how much land that could have been used for production they will instead preserve for the retention of nutrients. I develop three propositions. First, when the regulatory constraint is relatively weak, there will be a corner solution in which no land is set aside to provide the service of nutrient retention. Second, for any given regulatory constraint, there is a maximum amount of land that would be set aside to provide ecosystem services, regardless of the efficiency with which preserved land performs the nutrient retention function. Third, when it would prove very valuable to set some land aside for nutrient retention, less land in total may optimally be preserved for this purpose than when the service is less valuable. I illustrate the implications of this model with an application to the Chesapeake Bay watershed.Original Abstract: Depuis les dernieres decennies, les services ecosystemiques suscitent beaucoup d'interet. La retention des elements nutritifs figure parmi les services les plus mentionnes. Dans le present article, j'ai elabore un modele simple d'utilisation des terres agricoles qui tient compte d'une exigence reglementaire selon laquelle les charges en elements nutritifs ne peuvent exceder une quantite maximale etablie. Les agriculteurs decident de la quantite d'elements nutritifs residuels qu'ils genereront, des superficies qu'ils consacreront a la production et, par consequent, des superficies qui, au lieu d'etre consacrees a la production, seront reservees a la retention des elements nutritifs. J'ai formule trois propositions. Premierement, lorsque la limite reglementaire n'est pas fermement imposee, une solution speciale (corner solution) fera en sorte qu'aucune superficie ne sera reservee pour la retention des elements nutritifs. Deuxiemement, pour toute limite reglementaire etablie, des superficies maximales seront reservees pour offrir des services ecosystemiques, peu importe l'efficacite de retention des elements nutritifs de ces superficies. Troisiemement, lorsqu'il aura ete prouve que reserver des superficies pour la retention des elements nutritifs est d'une grande valeur, il se peut que les superficies reservees a cette fin soient inferieures a celles qui l'avaient ete lorsque le service avait une moindre valeur. J'ai illustre les incidences de ce modele en l'appliquant au bassin versant de la baie de Chesapeake.

The overall objectives of the study are to obtain a mercury emission model and provide a homeowner with cleanup procedures and disposal options for broken CFLs. An important component in achieving these objectives is the determination of the total mercury content in CFLs for the selection of bulbs to be used in the emission study. Most of the currently available CFLs in the United States (U.S.) market are manufactured in China for U.S. companies. Several different types of CFLs were purchased from local stores and the cap and electronic parts were removed without breaking the bulb. The bulb was then placed into a 2-L polypropylene bottle containing glass stoppers or glass marbles in a mixture of nitric acid and bromine monochloride solution (BrCl). The mixture was shaken to break the lamp and allow the mercury to be completely absorbed by the BrCl. The digested samples were analyzed for mercury using standard cold vapor atomic absorption (CVAA) methods. This CFL preparation method provides excellent results for laboratory control samples (typically, 90%-110% recovery) and good repeatability for CFL bulb analyses. The sampling and analysis phases of this study are discussed in this paper.

To determine the short-term impacts of prochloraz on gene expression and steroid production, adult female fathead minnows (Pimephales promelas) were exposed to the chemical (0 or 300 mu g/L) for a time-course of 6, 12 and 24h. Consistent with inhibition of cytochrome P450 17 alpha -hydroxylase/17,20-lyase (CYP17) and aromatase (CYP19), known molecular targets of prochloraz, plasma 17 beta -estradiol (E2) was reduced within 6h. Ex vivo E2 production was significantly reduced at all time-points, while ex vivo testosterone (T) production remained unchanged. Consistent with the decrease in E2 levels, plasma concentrations of the estrogen-responsive protein vitellogenin were significantly reduced at 24h. Genes coding for CYP19, CYP17, and steroidogenic acute regulatory protein were up-regulated in a compensatory manner in ovaries of the prochloraz-treated fish. In addition to targeted quantitative real-time polymerase chain reaction analyses, a 15k feature fathead minnow microarray was used to determine gene expression profiles in ovaries. From time-point to time-point, the microarray results showed a relatively rapid change in the differentially expressed gene (DEG) profiles associated with the chemical exposure. Functional analysis of the DEGs indicated changes in expression of genes associated with cofactor and coenzyme binding (GO:0048037 and 0050662), fatty acid binding (GO:0005504) and organelle organization and biogenesis (GO:0006996). Overall, the results from this study are consistent with compensation of the fish HPG axis to inhibition of steroidogenesis by prochloraz, and provide further insights into relatively rapid, system-wide, effects of a model chemical stressor on fish.

This study used concurrent and co-located data from both sources during the O3 season (May 1-September 30) for a four-year period (2002-2005). Regression models were developed for 74 areas across the Eastern U.S. The most important meteorological parameters used in the model were found to be daily maximum temperature and the daily average relative humidity (RH). Average morning and afternoon wind speed as well as factors for the day of the week and years were also included in the statistical models. R2 values above 60% were obtained for the majority of the locations in the analysis for both the ambient and CMAQ statistical models. Analysis of the covariate-specific effects revealed a tendency for the CMAQ model to underestimate how O3 increases with temperature. These results suggest that air quality forecasts that incorporate the CMAQ model may be underestimating the climate penalty on future O3 concentrations from warmer temperatures.

Several studies have documented zonation within the Rio Grande, but this is the first to quantitatively test the zonation hypothesis along a continuous 2800-km river profile, extending from the Rio Chama headwaters to the Gulf of Mexico. Using a large, multi-source dataset, I detected three ichthyofaunal zones: a high gradient ( similar to 1.5%) 'upper' zone, a moderate gradient ( similar to 0.2%) 'middle' zone and a low gradient (<0.1%) 'lower' zone. Species richness was lowest in the upper zone and highest in the lower zone, and all zones contained large numbers of nonnative species. However, species richness did not accumulate in a consistent, downstream manner. Instead, it tracked local-scale changes in mean annual discharge. This demonstrates the strong effect of river regulation and irrigation withdraws on fish diversity in the Rio Grande.

Methods: The types of nanomaterials, their uses, potential health effects and worker exposures, methods for examining worker and general population exposures, and risk management actions taken under the Toxic Substances Control Act (TSCA) prior to their manufacture are summarized. Results: There is a diversity of nanomaterials are currently entering the marketplace, but there are certain materials reviewed under TSCA such as carbon-based nanomaterials and metal oxides that are more likely to be commercialized than others. There are health and monitoring data that have been received by EPA that are useful in determining potential risks, and risk management approaches such as limiting uses of the nanomaterials and embedding nanomaterials in polymer matrices that reduce concerns for worker exposures. Certain EPA data gathering tools such as those used to collect nanomaterial use and worker exposure information, and screening level approaches for estimating worker exposures are useful and could be enhanced to better estimate worker risks. Conclusions: The data and experiences with nanomaterials under TSCA should prove useful when considering worker exposure registries, medical surveillance and epidemiological research.

NATA publishes estimates at the spatial resolution of U.S. Census tracts, which are subdivisions of a county. These local scale, model-predicted estimates from NATA are used extensively in community-based assessments; however, evaluation of NATA's ambient concentrations and human exposure estimates against measurement data has been limited to date. This paper compares modeled annual average benzene results from the 2002 NATA with measured results from the 2004 to 2007 Detroit Exposure and Aerosol Research Study (DEARS) as a case study of the quality of NATA results. NATA model estimates support community-scale characterization and assessment. Benzene is particularly important as it was estimated by the 2002 NATA as the largest single air toxic pollutant in terms of cancer risk in the U.S. We found that the average ambient concentrations of benzene predicted by NATA were within 5 percent, on average, of the 24-h integrated average ambient concentrations measured in DEARS. The NATA human exposure estimates, which include only outdoor sources for benzene, were, on average, approximately half the measured breathing zone concentrations from DEARS. Our analyses support that the factors driving higher DEARS personal benzene concentrations relative to the NATA predicted exposure values are likely due, at least in part, to indoor sources. This work points to further community-scale modeling research to improve characterizations and assessments of human exposures.

AN - 864786840; 21534884 AB - There is growing concern that exposure to air pollutants during pregnancy affects health outcomes in the offspring due to alterations in the development of immune and other homeostatic processes. To assess the risks of maternal inhalation exposure to ozone (O(3)), timed pregnant BALB/c mice were exposed to different concentrations of O(3) (0, 0.4, 0.8, and 1.2 ppm) for 4 h/day for 10 days during gestation (GD9-GD18), and pulmonary inflammation and immune responses were assessed in the offspring at 6 weeks-of-age. Maternal O(3) exposure reduced the number of productive dams by 25% at the highest O(3) concentration (1.2 ppm) and decreased the rate of weight gain in the offspring. Delayed-type hypersensitivity responses to bovine serum albumin were suppressed in the female offspring by maternal exposure to the two highest concentrations of O(3), whereas humoral immune responses to sheep red blood cells were not altered in either sex. Maternal exposure to 1.2 ppm O(3) increased lactate dehydrogenase (LDH) activity in bronchoalveolar lavage fluid (BALF) of the offspring but did not affect the number of inflammatory cells or levels of total protein, IFN-γ, IL-17, and IL-4 cytokines in BALF, or CD4(+), CD8(+), CD25(+), and TCRβ(+)CD1d(+) T-cells in the spleen. Offspring born from air-exposed dams sensitized early in life (postnatal day [PND] 3) to ovalbumin (OVA) antigen and then challenged as adults developed eosinophilia, elevated levels of LDH activity and total protein in BALF, and increased pulmonary responsiveness to methacholine, compared with animals sensitized at PND42. Maternal O(3) exposure in the 1.2 ppm O(3) group decreased BALF eosinophilia and serum OVA-specific IgE in the female offspring sensitized early in life but did not affect development of allergic airway inflammation by offspring sensitized late in life. In summary, maternal exposure to O(3) affected reproductive outcome and produced modest decreases in immune function and indicators of allergic lung disease in surviving offspring.

Under certain conditions (including appropriate stratification of the sampled population, sufficient density of samples, and sufficient range of exposure levels paired with concurrent response values), this empirical approach provides estimates of risk using extant field-derived monitoring data. The monitoring data were used to prescribe the exposure field and to model the exposure-response relationship. We illustrate this approach by estimating risks to benthic communities from low dissolved oxygen (DO) in freshwater streams of the mid-Atlantic region and in estuaries of the Virginian Biogeographical Province of the United States. In both cases, the estimates of risk are consistent with the U.S. EPA's ambient water quality criteria for DO.

However, the proteins and signaling pathways associated with the engineered nanomaterial-mediated oxidative stress and toxicity are largely unknown. To identify these toxicity pathways and networks that are associated with exposure to engineered nanomaterials, an integrated proteomic study was conducted using human bronchial epithelial cells, BEAS-2B and nanoscale titanium dioxide. Utilizing 2-DE and MS, we identified 46 proteins that were altered at protein expression levels. The protein changes detected by 2-DE/MS were verified by functional protein assays. These identified proteins include some key proteins involved in cellular stress response, metabolism, adhesion, cytoskeletal dynamics, cell growth, cell death, and cell signaling. The differentially expressed proteins were mapped using Ingenuity Pathway Analyses super((TM)) canonical pathways and Ingenuity Pathway Analyses tox lists to create protein-interacting networks and proteomic pathways. Twenty protein canonical pathways and tox lists were generated, and these pathways were compared to signaling pathways generated from genomic analyses of BEAS-2B cells treated with titanium dioxide. There was a significant overlap in the specific pathways and lists generated from the proteomic and the genomic data. In addition, we also analyzed the phosphorylation profiles of protein kinases in titanium dioxide-treated BEAS-2B cells for a better understanding of upstream signaling pathways in response to the titanium dioxide treatment and the induced oxidative stress. In summary, the present study provides the first protein-interacting network maps and novel insights into the biological responses and potential toxicity and detoxification pathways of titanium dioxide.

Almost the entire study area is geologically characterized by a thick succession of ignimbrites, tephra fallouts and lava flow deposits locally subjected to zeolitization. Among zeolites, fibrous erionite represents a well-known health hazard and so this work aims at locating and quantifying the presence of fibrous zeolites in volcanic deposits of the Viterbo area, suggesting at the same time a standard operational procedure useful in other areas showing the same possible hazard. 41 samples collected in the Viterbo area were analyzed by X-ray powder diffraction, optical and electron microscopy. Fibrous zeolites were detected in five samples and quantified in amounts ranging from 0.35 to 1.66% vol.

Daily averages of measured NO2 concentrations in the metropolitan Paris area are used as indicators of human exposure to urban air pollution from 2000 to 2004. The NO2 time series was decomposed with wavelet analysis to six independent variables representing different durations of population exposure. We used these variables as predictors in a mortality regression model and compared the coefficients estimated for the different timescales. We found a strong dependency of the exposure-response function on the duration of the air-pollution event. In contrast to previous studies that showed a monotone increase in the relationship between exposure to air-pollution and mortality from shorter to longer timescales, our results show a non-linear response suggesting that the overall acute effect consists of two discrete patterns: a short-term response (2 to 15 days) where mortality relative risks decrease to near null values with the duration of the air-pollution event; an intermediate timescale pattern (16 to 55 days) where mortality relative risk climbs back up to positive levels. The revealed pattern suggests that the overall acute effect of air-pollution on mortality reflects not only a short-term mortality displacement in a population already at high death risk due to chronic conditions but also the transition into this pool from the healthy population.

We evaluated the effect of synoptic circulation patterns (air masses) on the association between ozone and hospital admissions for asthma and myocardial infarction (MI) among adults in North Carolina. Daily surface meteorology data (including precipitation, wind speed, and dew point) for five selected cities in North Carolina were obtained from the U.S. EPA Air Quality System (AQS), which were in turn based on data from the National Climatic Data Center of the National Oceanic and Atmospheric Administration. We used the Spatial Synoptic Classification system to classify each day of the 9-year period from 1996 through 2004 into one of seven different air mass types: dry polar, dry moderate, dry tropical, moist polar, moist moderate, moist tropical, or transitional. Daily 24-hour maximum 1-hour ambient concentrations of ozone were obtained from the AQS. Asthma and MI hospital admissions data for the 9-year period were obtained from the North Carolina Department of Health and Human Services. Generalized linear models were used to assess the association of the hospitalizations with ozone concentrations and specific air mass types, using pollutant lags of 0 to 5 days. We examined the effect across cities on days with the same air mass type. In all models we adjusted for dew point and day-of-the-week effects related to hospital admissions. Ozone was associated with asthma under dry tropical (1- to 5-day lags), transitional (3- and 4-day lags), and extreme moist tropical (0-day lag) air masses. Ozone was associated with MI only under the extreme moist tropical (5-day lag) air masses. Elevated ozone levels are associated with dry tropical, dry moderate, and moist tropical air masses, with the highest ozone levels being associated with the dry tropical air mass. Certain synoptic circulation patterns/air masses in conjunction with ambient ozone levels were associated with increased asthma and MI hospitalizations.

The Mechanistic Indicators of Childhood Asthma study was designed to pilot an integrative approach in children's health research. The study incorporates exposure metrics, internal dose measures, and clinical indicators to decipher the biological complexity inherent in diseases such as asthma and cardiovascular disease with etiology related to gene-environment interactions. 205 non-asthmatic and asthmatic children, (9-12 years of age) from Detroit, Michigan were recruited. The study includes environmental measures (indoor and outdoor air, vacuum dust), biomarkers of exposure (cotinine, metals, total and allergen specific Immunoglobulin E, polycyclic aromatic hydrocarbons, volatile organic carbon metabolites) and clinical indicators of health outcome (immunological, cardiovascular and respiratory). In addition, blood gene expression and candidate SNP analyses were conducted. Based on an integrative design, the MICA study provides an opportunity to evaluate complex relationships between environmental factors, physiological biomarkers, genetic susceptibility and health outcomes.

AN - 866531406; 21495631 AB - Breast milk samples collected during 2003-2005 from 82 first-time mothers in 24 communities located throughout California contained levels of polybrominated diphenyl ethers (∑(tri-hexa (8))PBDEs; median = 53.3 ng/g lw, range = 9.60-1291) and polychlorinated biphenyls (∑(12)PCBs; median = 73.4 ng/g lw, range = 22.2-433) that are among the highest in the world. PBDE levels varied 100-fold. BDE-47 was the dominant PBDE congener, with levels exceeding the U.S.EPA Reference Dose (RfD) for neurodevelopmental toxicity (100 ng/kg/day) in most (60%) breast milk samples. In some samples, BDE-209 (2/82) and/or BDE-153 (5/82) were the dominant congeners, suggesting that BDE-209 can transfer to breast milk and/or break down in the mother and transfer to the nursing infant as the lower-brominated PBDEs associated with adverse effects. PBDE levels in California breast milk are approaching those of PCBs, and the trend PBDEs > PCBs may continue as PBDEs migrate from products to the indoor and outdoor environments.

Since there are limited disposal options for the petroleum-contaminated sediments (PCSs) of the canal, the environmental impact of IHC dewatered sediment when used as partial replacement of the aggregate used in hot mix asphalt (HMA) for road construction was investigated. In order to assess the long term migration of the target contaminants into the environment, the TCLP, SPLP, and a Constant pH leaching test were applied to a HMA mixture containing 10% of dewatered PCS, a conventional HMA, and the dewatered PCS. None of the heavy metals significantly leached from any of the tested materials in any of the conducted tests. Despite the presence of PAHs in the PCS, these were not found in any of the leachate samples. Finally, among the measured VOCs, only acetone and 2-butanone were found to leach from the asphalt mixtures and the sediment in the Constant pH experiment. It was concluded that it may be environmentally safe to replace the aggregates of the HMA used in road construction in the studied proportions with dewatered PCS based upon leaching levels as compared to TCLP regulated levels. This could be a viable, beneficial use option for the PCS, and therefore, for the canal remediation.

15495541 AB - Current breakthroughs in green nanotechnology are capable of transforming many of the existing processes and products that enhance environmental quality, reduce pollution, and conserve natural and nonrenewable resources. Successful use of metal nanoparticles and nanocomposites in various catalytic applications, electronics, biology and biomedical applications, material science, physics, environmental remediation and interdisciplinary fields as well as their toxicity essentially depends on the structural features such as size, shape, composition and the surface chemistry of nanomaterials. Moreover, to prolong the life span of metal nanoparticles and avoid undesired effects such as aggregation in aqueous solutions and organic solvents, to prevent contamination of the environment as well as to reuse and recycle nanoparticles, it is vital to select stabilizing agents and functionalization pathways that are environmentally friendly, non toxic and easy to implement. In recent years, stabilization and surface functionalization of metal nanoparticles became 'greener' to the extent that biocompatible stabilizing agents, e.g. biodegradable polymers and enzymes among others were introduced. These agents were able to produce a great variety of extremely stable spherical-, rod- or flower-shaped metal nanoparticles that opened up vast opportunities for their utilization and potential mass production. This review summarizes the state-of-the-art in the use of biocompatible and biodegradable homo- and copolymers as well as enzymes for the production of stable, environmentally benign, selective and active metal nanoparticles for desired applications.

Adherent mESCs were used to evaluate chemical-induced effects on both stem cell viability and differentiation using an in-cell western technique after a 9-day culture. DRAQ5/Sapphire700 stains were used to quantify cell number. Myosin heavy chain protein was used as a marker of cardiomyocyte differentiation and was corrected for cell number, thereby separating cytotoxicity and effects on differentiation. Acetic acid, 5-fluorouracil and bromochloroacetic acid were evaluated using the embryonic stem cell test and ACDC assay. Both systems distinguish the relative potencies of these compounds. TaqMan low-density arrays were used to characterize the time course of differentiation and effects of chemical exposure on multiple differentiation gene markers. The ACDC assay is a technique that can be used to evaluate the effects of xenobiotics on mESC differentiation and cell number using a single assay.

The inversion is formulated in the frequency domain using the vector Helmholtz equation. The objective function is minimized using a back-propagation method that is suitable for a 2.5D model and that accounts for the near-, intermediate-, and far-field regions of the antennas. The inversion is tested with crosswell radar data collected in a laboratory tank. The model anomalies are consistent with the known heterogeneity in the tank; the model's relative dielectric permittivity, which is calculated from the real part of the estimated complex slowness, is consistent with independent laboratory measurements. The methodologies developed for this inversion can be adapted readily to inversions of seismic data (e.g., crosswell seismic and vertical seismic profiling data).

The amount of CMM generated at a specific operation depends on the productivity of the coal mine, the gassiness of the coal seam and any underlying and overlying formations, operational variables, and geological conditions. CMM can be captured by engineered boreholes that augment the mine's ventilation system or it can be emitted into the mine environment and exhausted from the mine shafts along with ventilation air. The large amounts of methane released during mining present concerns about adequate mine ventilation to ensure worker safety, but they also can create opportunities to generate energy if this gas is captured and utilized properly. This article reviews the technical aspects of CMM capture in and from coal mines, the main factors affecting CMM accumulations in underground coal mines, methods for capturing methane using boreholes, specific borehole designs for effective methane capture, aspects of removing methane from abandoned mines and from sealed/active gobs of operating mines, benefits of capturing and controlling CMM for mine safety, and benefits for energy production and greenhouse gas (GHG) reduction.

The Standard Operating Procedures (SOPs) for Residential Exposure Assessment are intended to provide a screening-level assessment to estimate exposure for regulatory purposes. Nonetheless, dermal exposure estimates were typically lower from the SOP (1-1300nmol/day) than from SHEDS (5-19,000nmol/day) or any of the four different approaches for estimating dermal exposure using the Draft Protocol for Measuring Children's Non-Occupational Exposure to Pesticides by all Relevant Pathways (Draft Protocol) (5-11,000nmol/day). Indirect ingestion exposure estimates ranged from 0.02 to 21.5nmol/day for the SOP, 0.5 to 188nmol/day for SHEDS, and 0 to 3.38nmol/day for the Draft Protocol. Estimates of total absorbed dose ranged from 3 to 37nmol/day for the SOPs, 0.5 to 100nmol/day for SHEDS, and 1 to 216nmol/day for the Draft Protocol. The concentrations estimated using the Draft Protocol and SHEDS showed strong, positive relationships with the 3-phenoxybenzoic acid metabolite measured in the children's urine samples (R super(2)=0.90 for the Draft Protocol; R super(2)=0.92 for SHEDS). Analysis of different approaches for estimating dermal exposure suggested that the approach assuming an even distribution of pesticide residue on the child's body was most reasonable. With all three methodologies providing reasonable estimates of exposure and dose, selection should depend on the available data and the objectives of the analysis. Further research would be useful to better understand how best to estimate dermal exposure for children and what exposure factors (e.g., activities, transfer coefficients, measurement techniques) are most relevant in making dermal exposure estimates.

This information raises questions regarding the reliability of using these same metabolites, TCP and IMP, as urinary biomarkers to quantitatively assess the everyday exposures of children to CPF and DZN, respectively. In this study, we quantified the distributions of CPF, DZN, TCP, and IMP in several environmental and personal media at the homes and day-care centers of 127 Ohio preschool children and identified the important sources and routes of their exposures. The children were exposed to concurrent levels of these four chemicals from several sources and routes at these locations. DZN and IMP were both detected above 50% in the air and dust samples. CPF and TCP were both detected in greater than 50% of the air, dust (solid), food, and hand wipe samples. TCP was detected in 100% of the urine samples. Results from our regression models showed that creatinine levels (<0.001), and dietary (P<0.001) and inhalation (P<0.10) doses of TCP were each significant predictors of urinary TCP, collectively explaining 27% of the urinary TCP variability. This information suggests that measurement of urinary TCP did not reliably allow quantitative estimation of the children's everyday environmental exposures to CPF.

Monitoring was performed at three school sites in East Harlem, the Bronx, and Brooklyn for 1month per year over a two-year period from November 2006aOctober 2008. Monitoring at each site was conducted before and after the Asthma Free School Zone (AFSZ) asthma reduction education program was administered. Real-time equipment with a one-minute averaging interval was used to obtain the BC data, while volume counts of idling and passing school busses, trucks, and automobiles were collected each minute by study staff. These data were matched to ambient PM2.5 and meteorology data obtained from the New York State Department of Environmental Conservation. A generalized additive model (GAM) model was run to examine the relationship between BC concentration and each variable while accounting for site-to-site differences. F-tests were employed to assess the significance of each of the predictor variables. The model results suggested that variability in ambient PM2.5 concentration contributed 24% of the variability in transformed BC concentration, while variability in the number of idling busses and trucks on the street during dismissal contributed 20% of the variability in transformed BC concentration. The results of this study suggest that a combination of urban scale and local traffic control approaches in combination with cessation of school bus idling will produce improved local BC concentration outside schools. Research highlightsao Studied short-term elevations in black carbon, potentially an asthma trigger. ao Log-transformed BC significantly associated with idling school busses and trucks, ambient PM2.5. ao Results suggest traffic control will improve microenvironmental air quality.

In this study, surface enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) coupled with a short term fish assay was used to investigate changes in plasma protein expression as a means to screen chemicals for androgenic activity. Adult gravid female sheepshead minnows (Cyprinodon variegatus) were placed into separate aquaria for seawater control, ethanol solvent control, and the following androgen agonist treatments at 5.0 mu g/L: dihydrotestosterone (DHT), methyldihydrotestosterone (MDHT), testosterone (T), methyltestosterone (MT) and trenbolone (TB). Treatments of 0.6 mu g/L endosulfan and 40 mu g/L chlorpyrifos (CP) served as non-androgenic negative stressor controls. Test concentrations were maintained using an intermittent flow-through dosing apparatus supplying exposure water at 20L/h. Fish were sampled at 7 days, the plasma diluted, processed on weak cation exchange CM10 ProteinChip arrays and analyzed. Spectral processing resulted in 249 individual m/z peak clusters for the androgen exposed fish. Partial least squares-discriminant analysis was used to develop an androgen-responsive model using sample spectra from exposures with DHT and unexposed solvent control fish as the training set. The androgen classification model performed with greater than or equal to 79% specificity (% true negative) and greater than or equal to 70% sensitivity (% true positive) for non-aromatizable androgens. The aromatizable androgens T and MT were classified as androgenic with specificities of 42 and 79%, respectively. The reduction in sensitivity observed with T is thought to be caused by its metabolic conversion to an estrogen by aromatase.

Real-time PCR methods are available which can measure results in as little as 3h. The purpose of this study was to evaluate a more rapid test method for the determination of bacterial contamination in marine bathing beaches to better protect human health. The geometric mean of Enterococcus densities using EnterolertA registered defined substrate testing and membrane filtration ranged from 5.2 to 150MPN or CFU/100mL and corresponding qPCR results ranged from 6.6 to 1785CCE/100mL. The regression analysis of these results showed a positive correlation between qPCR and conventional tests with an overall correlation (r) of 0.71. qPCR was found to provide accurate and sensitive estimate of Enterococcus densities and has the potential to be used as a rapid test method for the quantification of Enterococcus in marine waters.

There was a significant increasing trend in DO in the upstream portion of the estuary during the years 1960-1985. Historically, minimum dry season (May-October) DO levels occurred about 20aakm from the estuary mouth at warm water temperatures, near both point source discharges and where extensive log rafting occurred. Presently, there is a trend of increasing dry season DO with increasing distance from the mouth of the estuary. Minimum DO levels occur at cool water temperatures (8 degree C), suggesting that recently upwelled oceanic water from the shelf is the source of the low DO water. Recent time-series data (2001-2007) demonstrates that the water advected into the estuary from the coastal ocean has DO levels<5mgl super(-1) about 13% of the time during the dry season and that water temperature is a good indicator of the oceanic source. Similarity in the flood-tide DO and water temperature relationship between recent time-series data in Yaquina and in historic data from other estuaries suggests that the hypoxic conditions observed off the Oregon coast since 2002 may have occurred previously, especially during the 1950's-1960's. It is important to characterize the natural background DO levels for estuaries in the region to be able to separate anthropogenic from natural influences on DO.

We conducted a national, watershed-level environmental assessment of 5,265 drinking water watersheds using data on land cover, hydrography and conservation status. Approximately 78% of the conterminous United States lies within a drinking water watershed. The typical drinking water watershed had a high percentage of natural vegetation ( x = 77%) but a low percentage of it was set aside for conservation ( x = 3%). Median percentage values for urban and agriculture were 5 and 8%, respectively. Between ca. 1992 and ca. 2001, approximately 23% of the drinking water watersheds lost at least 1% of their natural vegetation, and approximately 9% of the watersheds had at least a 1% increase in the amount of urban land. Loss of natural vegetation was common in nearly all areas of the country, but also concentrated in the Ohio River and Southeast hydrologic regions. Urbanization was concentrated in the eastern United States, primarily in the Mid-Atlantic and Southeast hydrologic regions.

Background concentrations are commonly converted to a single mean background concentration that is subtracted from tracer recovery data. To obtain an improved estimate for the mean background concentration, a statically-robust procedure addressing left-censored data and possible outliers in background concentration data is presented. A maximum likelihood estimate and other robust methods coupled with outlier removal are applied. Application of statically-robust procedures to background concentrations results not only in better estimates for mean background concentration but also results in more accurate quantitative analyses of tracer-breakthrough curves when the mean background concentration is subtracted.

A common goal for both regulatory authorities and permittees is confidence in an individual test result (e.g., no-observed-effect concentration [NOEC], pass/fail, 25% effective concentration [EC25]), which is used to make regulatory decisions, such as reasonable potential determinations, permit compliance, and watershed assessments. This paper discusses an additional statistical approach (test of significant toxicity [TST]), based on bioequivalence hypothesis testing, or, more appropriately, test of noninferiority, which examines whether there is a nontoxic effect at a single concentration of concern compared with a control. Unlike the traditional hypothesis testing approach in whole effluent toxicity (WET) testing, TST is designed to incorporate explicitly both alpha and beta error rates at levels of toxicity that are unacceptable and acceptable, given routine laboratory test performance for a given test method. Regulatory management decisions are used to identify unacceptable toxicity levels for acute and chronic tests, and the null hypothesis is constructed such that test power is associated with the ability to declare correctly a truly nontoxic sample as acceptable. This approach provides a positive incentive to generate high-quality WET data to make informed decisions regarding regulatory decisions. This paper illustrates how alpha and beta error rates were established for specific test method designs and tests the TST approach using both simulation analyses and actual WET data. In general, those WET test endpoints having higher routine (e.g., 50th percentile) within-test control variation, on average, have higher method-specific alpha values (type I error rate), to maintain a desired type II error rate. This paper delineates the technical underpinnings of this approach and demonstrates the benefits to both regulatory authorities and permitted entities.

Methods and Results: Spores were inoculated onto test coupons and positive control coupons of nine different materials. Six different sporicidal liquids were spray-applied to the test coupons and remained in contact for exposure times ranging from 10 to 70min. Following decontamination, spores were recovered from the coupons and efficacy was quantified in terms of log reduction. Conclusions: The hydrogen peroxide/peracetic acid products were the most effective, followed by decontaminants utilizing hypochlorous acid chemistry. Decontamination efficacy varied by material type. Significance and Impact of the Study: The study results may be useful in the selection of technologies to decontaminate buildings and outdoor areas in the event of contamination with B. anthracis spores. These results may also facilitate selection of decontaminant liquids for the inactivation of other spore-forming infectious disease agents.

AN - 864194701; 21469704 AB - Loblolly pine (Pinus taeda) was combusted at different charge sizes, fuel moisture, and chlorine content to determine the effect on emissions of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) as well as copollutants CO, PM, and total hydrocarbons. The experiments were performed in an enclosed chamber under conditions simulating open, prescribed burns of forest biomass. Burn progress was monitored through on line measurement of combustion gases and temperature while PCDD/F concentrations were determined by ambient sampling methods. PCDD/F toxic equivalency (TEQ) and total (tetra- to octa-CDD/F) emission factors were independent of charge size (1-10 kg) and moisture content (7-50%). However, the lower chlorinated, mono- to tri-CDD/F compounds were increased by poor combustion conditions: combustion efficiency lower than 0.919 was generally found when the moisture content was higher than 30%. The increase of fuel matrix chlorine from 0.04% to 0.8% using a brine bath resulted in about a 100-fold increase of PCDD/F to about 90 ng TEQ/kg of carbon burned, C(b). These emission factors were linearly dependent on Cl concentration in the biomass. PCDD 2,3,7,8-Cl-substituted congeners and homologue patterns were also influenced by the addition of chlorine resulting in emissions with a higher abundance of the most toxic congeners (TeCDD and PeCDD). When both chlorine and moisture content were increased in the fuel, a simultaneous effect of the two parameters was observed. The increased TEQ values expected from higher Cl concentrations were mitigated by the presence of water, giving MCE = 0.868, promoting formation of mono- to tri-PCDD/F, and lowering the TEQ value. Open burn simulations were used to study PCDD/F formation in different combustion conditions providing a mathematical correlation between PCDD/F emissions and chlorine and moisture content in the fuel.

AN - 863423671; 21278051 AB - Extensive research has lead to a growing appreciation that the heart is acutely sensitive to a broad array of toxicants via multiple routes of exposure. These agents are as diverse as the antineoplastic drug doxorubicin and environmental agents including ambient air pollution. Adverse effects in the heart often manifest as a change in the electrocardiogram (ECG). The ECG has long been used in the clinic to assess human cardiovascular health. Surface electrocardiographic recordings (i.e., those made from the skin) in humans often help to detect abnormal myocardial impulse formation, conduction, cardiac rhythm disturbances, and altered autonomic regulation of the heart. In toxicology, the ECG provides a collection of end points that may be used to assess both the quality and magnitude of cardiac toxicity. Increasingly over the last two decades, the cardiotoxicity of agents have been characterized using small rodent electrocardiography. Additionally, tremendous insight into possible mechanisms of action of known human cardiotoxicants has been gained. Rat and mouse models offer a number of advantages relative to larger animals including lower cost, less variability, the availability of transgenic models, and a plethora of research tools. Modern day advances in small rodent electrocardiography have enabled assessments in conscious unrestrained animals and improved ECG interpretation. Thus, the incorporation of small rodent electrocardiographic assessments into toxicology studies may facilitate the screening of cardiotoxic potential and the elucidation of mechanisms of action. This review will discuss the utility of the small rodent ECG, various methodologies used to derive ECG data in rats and mice, and various applications in toxicology.

Moreover, the specific energy consumption and simplified operational and treatment costs were calculated. Addition of Na sub(2H) sub(2)EDTA (at pH 7.7) to copper-amended sludge resulted in the highest microbial activity (62 mg CH sub(4-COD g VSS[super]-1 day[super]-1) suggesting that Na) sub(2)H sub(2EDTA decreased the toxic effects of copper on the methanogenic activity of the anaerobic granular sludge. The highest methane production (159 %) was also observed upon Na) sub(2)H sub(2EDTA addition and simultaneous electricity application (pH 7.7). The energy consumption during the treatment was 560, 840, 1400 and 1680 kW h m[super]-3 at current densities of 0.23, 0.34, 0.57 and 0.69 mA cm[super]-2, respectively. This corresponded to a treatment costs in terms of electricity expenditure from 39.2 to 117.6 [Euros] per cubic meter of sludge.)

In particular, the types of legal instruments, institutions, and the response of law to the inherent variability in social-ecological systems are critical. Sustainability likely must occur via the institutions we have in place, combined with alterations in policy and regulation within the context of these institutions. This ecosystem management arrangement can be characterized as a panarchy, with research on sustainability specific to the scale of interest. In this manuscript we examine an opportunity for integrating these concepts through a regulatory rebirth of the National Environmental Policy Act (NEPA). NEPA currently requires federal agencies to take a ''hard look'' at the environmental consequences of proposed action. The original intent of NEPA, however, was more substantive and its provisions, while currently equilibrium based, may be reconfigured to embrace new understanding of the dynamics of social-ecological systems.

Measurement error due to the use of indirect exposure surrogates can lead to misclassification bias in epidemiological studies; therefore, it is important to characterize exposure variability in these populations to assess the potential for exposure misclassification. We used 19,944 trihalomethane (THM) samples and 9291 haloacetic acid (HAA) samples collected in 201 public water systems (PWSs) in Massachusetts to examine temporal variability under different drinking water sources and disinfection types. Annual and seasonal variability was also examined in 46 PWSs with complete quarterly THM4 (i.e., the sum of 4 individual THMs) data from 1995 to 2004 and 19 PWSs with complete HAA5 (i.e., the sum of 5 individual HAAs) data from 2001 to 2004. The quarterly ratio of THM4 and HAA5 and correlations between THM4, HAA5 and individual DBP species were examined to determine the adequacy of using different exposure surrogates in epidemiological studies. Individual PWSs were used to examine monthly variability in relation to quarterly averages. Based on all available matched samples (n=9003) from 1995 to 2004 data, we found a correlation of 0.52 for THM4 and HAA5. The correlation was stronger among the 62 ground water systems (r s =0.62) compared to the 81 surface water (r sub(s) =0.45) and 40 mixed water (r sub(s) =0.39) systems. Mean THM4 levels were fairly stable over the 10-year study period for 46 PWSs including 39 PWSs that did not change disinfection. Large reductions (~ 40 mu g/L) in mean THM4 data were found among seven systems that switched from chlorination to alternative disinfectants. As expected, the highest mean THM4 values were detected for Quarter 3, while the lowest values were found in Quarter 1. The highest HAA5 values were detected in Quarters 2 and 3 and the lowest was found in Quarter 4. Data from four systems showed mean differences up to 66 mu g/L (67% change) in successive months and by 46 mu g/L compared to quarterly mean concentrations. Although longer-term disinfection by-product temporality may be minimal in this study population, the use of monthly average concentrations for exposure assessment may be needed for some PWSs to minimize misclassification of narrow critical periods of exposure in epidemiological studies.

Noah-GEM produced better Vd(O3) variations due to its more realistically simulated stomatal resistance (Rs) than WDDM. Vd(O3) is very sensitive to the minimum canopy stomatal resistance (Ri) which is specified for each seasonal category assigned in WDDM. Treating Sep-Oct as autumn in WDDM for this deciduous forest site caused a large underprediction of Vd(O3) due to the leafless assumption in aautumna seasonal category for which an infinite Ri was assigned. Reducing Ri to a value of 70sm super(-1) the same as the default value for the summer season category, the modeled and measured Vd(O3) agreed reasonably well. HNO3 was found to dominate the NOy flux during the measurement period; thus the modeled Vd(NOy) was mainly controlled by the aerodynamic and quasi-laminar sublayer resistances (Ra and Rb), both being sensitive to the surface roughness length (z0). Using an appropriate value for z0 (10% of canopy height), WDDM and Noah-GEM agreed well with the observed daytime Vd(NOy). The differences in Vd(HNO3) between WDDM and Noah-GEM were small due to the small differences in the calculated Ra and Rb between the two models; however, the differences in Rc of NO2 and PAN between the two models reached a factor of 1.1-1.5, which in turn caused a factor of 1.1-1.3 differences for Vd. Combining the measured concentrations and modeled Vd, NOx, PAN and HNO3 accounted for 19%, 4%, and 70% of the measured NOy fluxes, respectively.

A 3-dimensional computational fluid dynamics (CFD) 6-lane road model has been developed to simulate roadside barrier effects on near-road air quality and evaluate the influence of key variables, such as barrier height and wind direction. The CFD model matches an existing wind tunnel road model and comparison with the wind tunnel data guided the selection of the optimal turbulence model (Realizeable kaE turbulence model with a Schmidt number of 1.0). Under winds perpendicular to the road, CFD model simulations show that roadside barriers reduce the concentration of an inert gaseous tracer (I), relative to a no-barrier situation, vertically up to approximately half the barrier height and at all horizontal distances from the road. At 20m (3.3H, where H=6m) from the road, barriers of heights ranging from 0.5H to 3.0H reduce the maximum concentrations by 15-61% relative to a no-barrier case, with the location of the maximum shifted to occur near the top of the barrier. The near-road reduction comes at a penalty for on-road air pollutant concentrations: on-road pollution is projected to increase by a factor of 1.1-2.3 corresponding to barriers ranging from 0.5H to 3.0H. When the noise barrier is downwind of the road, a stagnant zone is formed behind the barrier and minor road emissions (e.g., 5% of the highway emissions strength) in this zone, such as a moderately traveled service road, have a magnified effect on concentrations immediately behind the barrier. Wind direction and barrier termination also play a critical role, with a spill-over of accumulated emissions upwind of the barrier strongly increasing near-road concentrations at one end of the barrier. These results imply that roadside barriers may mitigate near-road air pollution, although local meteorology, the barrier structure, and the degree of lee-side emission sources are critical factors determining the outcome.

In this work, the traditional Derjaguin - Landau - Verwey - Overbeek theory of colloidal particle stability was examined by using three published expressions for estimating critical coagulation concentrations (CCCs; i.e., the minimum ionic strength needed to induce rapid self-aggregation) via incorporation of diffuse-layer potential estimates obtained from MINTEQA2 geochemical model implementations of an enhanced version of the MIT diffuse-layer model (DLM) and the historical triple-layer model (TLM). Amorphous iron oxide was selected as a test colloid in this assessment and its electrostatic properties were simulated over a pH range of 4 to 10 in 0.7 M seawater, 0.1 M diluted seawater, world average river water, US continental average groundwater and Midwestern US 50th percentile rainwater. Findings from the study included: (1) sources of variation in predictions of the onset of rapid colloidal particle self-aggregation were observed to occur in the following order: aquatic chemistry > selection of DLM vs. TLM diffuse-layer potentials > uncertainties in the Hamaker constant > selection of CCC equation nearly equal the distance to the plane of shear (with the DLM), (2) the magnitude of the DLM diffuse-layer potential estimates exceeded that of the TLM estimates, (3) TLM diffuse-layer potential estimates were consistent with a conjecture by Loux and Anderson, Colloids and Surfaces A, 177, 123-131, (2001) that the magnitude of environmental interfacial potentials were likely to be less than RT/F ( nearly equal 25 mV) and DLM estimates were not, and (4) TLM estimates predict that amorphous iron oxide suspensions are likely to be relatively stable only in high pH rainwater; DLM estimates predict relative colloidal iron oxide suspension stability in rainwater and extreme pH river waters. These predictions of rapid aggregation are at least qualitatively in accord with data published in the literature.

This interest stems from legal mandates requiring assessments, plus growing recognition of the threats to such systems from multiple and co-varying stressors (e.g. chemical pollutants, physical habitat alterations, altered flow regimes, channel modifications and alien species). The elevated cost and inefficiencies of jurisdictionally- and taxonomically-segregated assessments is widely recognized, as is the desire to obtain comparable data that can be easily shared among political jurisdictions and ecological regions. The objectives, sampling methods, indicators, site-scale sampling designs and geographic extent of the resources being sampled differ among programmes, thereby limiting such data exchanges. Our objective in this paper is to review major biological assessment design alternatives for boatable rivers, with special attention given to the sample site length from which data are collected. We suggest that sufficient site length determinations should be based on the survey objectives, the relative heterogeneity of the habitat template, and the quality of data necessary for meeting programmatic data quality objectives. Future sampling effort studies should be designed to allow separate samples of several short sub-sites at many diverse sites to generate multiple data points for each site. Data from those multiple sub-sites should be analysed using randomization-based data evaluation methods. We hope that our recommendations will be useful to the maximum number of institutions, including those with limited funds and a purely local focus, as well as those responsible for sampling at continental geographic extents.

The implications of marginal ID, however, remain less well known. The current study examined the relationship between graded levels of ID in rats and serum thyroid hormones, thyroid iodine content, and urinary iodide excretion. The goals of this study were to provide parametric and dosearesponse information for development of a quantitative model of the thyroid axis. Female Long Evans rats were fed casein-based diets containing varying iodine (I) concentrations for 8 weeks. Diets were created by adding 975, 200, 125, 25, or 0I14g/kg I to the base diet (a1425I14g I/kg chow) to produce 5 nominal I levels, ranging from excess (basal+added I, Treatment 1: 1000I14g I/kg chow) to deficient (Treatment 5: 25I14g I/kg chow). Food intake and body weight were monitored throughout and on 2 consecutive days each week over the 8-week exposure period, animals were placed in metabolism cages to capture urine. Food, water intake, and body weight gain did not differ among treatment groups. Serum T4 was dose-dependently reduced relative to Treatment 1 with significant declines (19 and 48%) at the two lowest I groups, and no significant changes in serum T3 or TSH were detected. Increases in thyroid weight and decreases in thyroidal and urinary iodide content were observed as a function of decreasing I in the diet. Data were compared with predictions from a recently published biologically based dosearesponse (BBDR) model for ID. Relative to model predictions, female Long Evans rats under the conditions of this study appeared more resilient to low I intake. These results challenge existing models and provide essential information for development of quantitative BBDR models for ID during pregnancy and lactation.

AN - 862792956; 21388151 AB - The conventional scheme for arsenic methylation accounts for methylated oxyarsenical production but not for thioarsenical formation. Here, we report that in vitro anaerobic microbiota of mouse cecum converts arsenate into oxy- and thio- arsenicals. Besides methylarsonic acid (MMA(V)), arsenate was transformed into six unique metabolites: mono-, di-, and trithio-arsenic acid, monomethyldithio- and monomethyltrithio-arsonic acid, and dimethyldithioarsonic acid. Thioarsenicals were found in soluble and particulate fractions of reaction mixtures, suggesting interactions with anaerobic microbiota. Metabolism of ingested arsenate to oxy- and thio-arsenicals before absorption across the gastrointestinal barrier could affect bioavailability, systemic distribution, and resulting toxicity.

AN - 862790972; 21384849 AB - We describe a framework for estimating the human dose at which a chemical significantly alters a biological pathway in vivo, making use of in vitro assay data and an in vitro-derived pharmacokinetic model, coupled with estimates of population variability and uncertainty. The quantity we calculate, the biological pathway altering dose (BPAD), is analogous to current risk assessment metrics in that it combines dose-response data with analysis of uncertainty and population variability to arrive at conservative exposure limits. The analogy is closest when perturbation of a pathway is a key event in the mode of action (MOA) leading to a specified adverse outcome. Because BPADs are derived from relatively inexpensive, high-throughput screening (HTS) in vitro data, this approach can be applied to high-throughput risk assessments (HTRA) for thousands of data-poor environmental chemicals. We envisage the first step of HTRA to be an assessment of in vitro concentration-response relationships across biologically important pathways to derive biological pathway altering concentrations (BPAC). Pharmacokinetic (PK) modeling is then used to estimate the in vivo doses required to achieve the BPACs in the blood at steady state. Uncertainty and variability are incorporated in both the BPAC and the PK parameters and then combined to yield a probability distribution for the dose required to perturb the critical pathway. We finally define the BPADL as the lower confidence bound of this pathway-altering dose. This perspective outlines a framework for using HTRA to estimate BPAD values; provides examples of the use of this approach, including a comparison of BPAD values with published dose-response data from in vivo studies; and discusses challenges and alternative formulations.

14563851 AB - Barium carbonate and/or barium carbonate-loaded silica aero-gels dispersed polyvinyl chloride (PVC) composites were prepared by dissolving PVC in tetrahydrofuran (THF), dispersing BaCO3 and/or BaCO3-loaded silica aero-gels, re-precipitating the PVC with water at room temperature. The PVC composites were then characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray mapping, X-ray diffraction (XRD), thermogravimetric analysis (TGA) and inductively coupled plasma mass spectrometry (ICP-MS) analysis. The obtained composites had better thermal properties than the control PVC. The composites were tested for sulfate removal and found to significantly reduce sulfate when compared with control PVC. BaCO3 dispersed PVC composites were prepared through a polymer re-precipitation method. The composites were tested for sulfate removal using rapid small scale column test (RSSCT) and found to significantly reduce sulfate concentration. The method was extended to synthesize barium carbonate-loaded silica aero-gels-polyvinyl chloride (PVC) polymer composites. The PVC composites were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray mapping, X-ray diffraction (XRD), thermogravimetric analysis (TGA) and inductively coupled plasma mass spectrometry (ICP-MS) analysis. The method has advantages over conventional sulfate precipitation (sulfate removal process) using BaCO3 wherein clogging of the filter can be avoided. The method is environmentally friendly and does not interfere with natural organic matter as the conventional resin does. Some of the composites were thermally more stable as compared with the pure PVC discussed in the literature.

AN - 862005953; 21417318 AB - Omic technologies offer unprecedented opportunities to better understand mode(s)-of-toxicity and downstream secondary effects by providing a holistic view of the molecular changes underlying physiological disruption. Crustacean hemolymph represents a largely untapped biochemical resource for such toxicity studies. We sought to characterize changes in the hemolymph metabolome and whole-body transcriptome to reveal early processes leading to chronic toxicity in the indicator species, Daphnia magna, after 24-h sublethal cadmium exposure (18 μg/L, corresponding to 1/10 LC(50)). We first confirmed that metabolites can be detected and identified in small volumes (∼3-6 μL) of D. magna hemolymph using Fourier transform ion cyclotron resonance mass spectrometry and NMR spectroscopy. Subsequently, mass spectrometry based metabolomics of hemolymph identified disruption to two major classes of metabolites: amino acids and fatty acids. These findings were compared to differentially expressed genes identified by a D. magna 44k oligonucleotide microarray, which included decreased levels of digestive enzymes and increased expression of cuticle proteins and oxidative stress response genes. The combination of metabolic and transcriptional changes revealed through KEGG pathway analysis and gene ontology, respectively, enabled a more complete understanding of how cadmium disrupts nutrient uptake and metabolism, ultimately resulting in decreased energy reserves and chronic toxicity.

The as-prepared catalytic adsorbents were characterized by X-ray diffraction (XRD) and diffuse reflectance spectroscopy (DRS). Surface morphology was evaluated by means of scanning electron microscopy (SEM) equipped with EDS. The solution phase photocatalytic activity was assessed by the degradation of a relevant concentration of MO and dichlorophenol (DCP) in the presence of visible light irradiation from 300W metal halogen desk lamp. Bi/Cu-pillared montmorillonite completely destroyed and bleached MO (initial concentration of 160mgL super(-1) after adsorption in the dark) and completely degraded DCP (initial concentration of 86mgL super(-1) after adsorption in the dark) in 120 and 240 min, respectively. It was also observed that the most effective dosage for the removal of MO and DCP, respectively, was 1gL super(-1) (98% and 95% removal efficiencies) followed by 0.5 (82% and 70%), 2 (80% and 70%) and 3gL super(-1) (75% and 65%). The reaction rates at 1gL super(-1) catalyst loadings were k d 2.1 x 10 super(-2) min super(-1) and 1.18 x 10 super(-2) min super(-1) for MO and DCP, respectively. Total organic carbon (TOC) decreased by 95 and 70% in 120 and 240 min of the treatment when MO and DCP, respectively, were introduced. Actual turnovers (ATON), turnover frequency (TOF) and quantum efficiency (Q sub(2)) for MO, which was selected as the representative target contaminant for the photo-induced adsorption process, were 12.5, 6.25h super(-1) and 43.8%, respectively.

External disease forcing, rather than contagious spread, explained five of six diseases. Outbreaks of some diseases were associated with coral bleaching. Coral populations were projected to decline even in absence of disease and bleaching. Coral diseases have increased in frequency over the past few decades and have important influences on the structure and composition of coral reef communities. However, there is limited information on the etiologies of many coral diseases, and pathways through which coral diseases are acquired and transmitted are still in question. Furthermore, it is difficult to assess the impacts of disease on coral populations because outbreaks often co-occur with temperature-induced bleaching and anthropogenic stressors. We developed spatially explicit population models of coral disease and bleaching dynamics to quantify the impact of six common diseases on Florida Keys corals, including aspergillosis, dark spots, white band, white plague, white patch, and Caribbean yellow band. Models were fit to an 8-year data set of coral abundance, disease prevalence, and bleaching prevalence. Model selection was used to assess alternative pathways for disease transmission, and the influence of environmental stressors, including sea temperature and human population density, on disease prevalence and coral mortality. Classic disease transmission from contagious to susceptible colonies provided the best-fit model only for aspergillosis. For other diseases, external disease forcing, such as through a vector or directly from pathogens in the environment, provided the best fit to observed data. Estimates of disease reproductive ratio values (R 0) were less than one for each disease, indicating coral colonies were below densities required for diseases to become established through contagious spread alone. Incidences of white band and white patch disease were associated with greater susceptibility or slower recovery of bleached colonies, and no disease outbreaks were associated with periods of elevated sea temperatures alone. Projections of best-fit models indicated that, atleast during the period of this study, disease and bleaching did not have substantial impacts on populations and impaired rates of population growth appeared to be attributable to other stressors. By applying epidemiological models to field data, our study gives qualitative insights into the dynamics of coral diseases, relative stressor impacts, and directions for future research.

Samples taken once during the course of the day cannot adequately reflect diel variations in water quality and may result in an inaccurate understanding of biogeochemical processes, ecological conditions, and of the threat posed by the water to human health and the associated wildlife. Surface water and groundwater affected by acid drainage were sampled every 60 to 90 min over a 48-hour period at a former zinc smelter known as the Hegeler Zinc Superfund Site, near Hegeler, Illinois. Diel variations related to water quality in the aquifer were not observed in groundwater. Diel variations were observed in the temperature, pH, and concentration of dissolved oxygen, nitrite, barium, iron, lead, vanadium, and possibly uranium in surface water. Temperature, dissolved oxygen, nitrite, barium, lead, and uranium generally attained maximum values during the afternoon and minimum values during the night. Iron, vanadium, and pH generally attained minimum values during the afternoon and maximum values during the night. Concentrations of dissolved oxygen were affected by the intensity of photosynthetic activity and respiration, which are dependent upon insolation. Nitrite, an intermediary in many nitrogen reactions, may have been formed by the oxidation of ammonium by dissolved oxygen and converted to other nitrogen species as part of the decomposition of organic matter. The timing of the pH cycles was distinctly different from the cycles found in Midwestern alkaline streams and likely was the result of the photoreduction of Fe (super 3+) to Fe (super 2+) and variations in the intensity of precipitation of hydrous ferric oxide minerals. Diel cycles of iron and vanadium also were primarily the result of variations in the intensity of precipitation of hydrous ferric oxide minerals. The diel variation in the concentrations of lead, uranium, and barium may have been affected by competition with Fe (super +2) for sorption sites on hydrous ferric oxide minerals.

Forty-six ambient PM2.5 samples were collected on a one in six schedule and analyzed for (1) secondary organic aerosol tracer compounds, and (2) levoglucosan, a compound used as a tracer for biomass burning. For isoprene, alpha -pinene, beta -caryophyllene, and toluene, the secondary contributions to ambient organic carbon concentrations (OC) were estimated using measured tracer concentrations and previously established, laboratory-determined mass fractions. The estimates show secondary formation from these four hydrocarbons contributes up to 55% of the ambient organic carbon concentrations (Julian day 197) when OC was 5.98 mu g C/m super(3). The relative contributions are highly temperature dependent; estimates of particulate carbon from isoprene and alpha -pinene precursors peaked during the warmest days, and represented up to 40% and 10% of the measured OC, respectively (Julian days 197 and 191). Conversely, biomass burning represented up to 21% of the organic carbon concentrations on the coldest day sampled, Julian day 329, while contributions of secondary organic carbon from these four precursor hydrocarbons remained low at 4% of the measured 2.55 mu g C/m super(3) OC.

Those models usually require a large set of input parameters and separate simulations for each pesticide in evaluation. In this study, a simple use-exposure relationship is developed based on regression analysis of stochastic simulation results generated from the Pesticide Root-Zone Model (PRZM). The developed mathematical relationship estimates edge-of-field peak concentrations of pesticides from aerobic soil metabolism half-life (AERO), organic carbon-normalized soil sorption coefficient (KOC), and application rate (RATE). In a case study of California crop scenarios, the relationships explained 90a95% of the variances in the peak concentrations of dissolved pesticides as predicted by PRZM simulations for a 30-year period. KOC was identified as the governing parameter in determining the relative magnitudes of pesticide exposures in a given crop scenario. The results of model application also indicated that the effects of chemical fate processes such as partitioning and degradation on pesticide exposure were similar among crop scenarios, while the cross-scenario variations were mainly associated with the landscape characteristics, such as organic carbon contents and curve numbers. With a minimum set of input data, the use-exposure relationships proposed in this study could be used in screening procedures for potential water quality impacts from the off-site movement of pesticides.

Heterozygous mice of strain B6; 129S7-Sod1tm1Leb/J were obtained from Jackson Laboratories and bred to produce offspring that were heterozygous (+/Sod1tm1Leb), homozygous wild-type (+/+), and homozygous knockout (Sod1tm1Leb/Sod1tm1Leb) for the Cu/Zn superoxide dismutase (Sod1) gene. Splenocytes from these mice were exposed to several concentrations of either sodium arsenite (As3 [0-200 mu M]), monomethylarsonous acid (MMA3 [0-10 mu M]), or dimethylarsinous acid (DMA3 [0-10 mu M]) for 2 hr. Cells were then examined for DNA damage using the alkaline single cell gel electrophoresis assay. Methyl methanesulfonate (MMS) was used as a positive control. Splenocytes from each of the three genotypes for Sod1 were equally sensitive to MMS and As3. However, at equimolar concentrations, DMA3 and MMA3 produced significantly more DNA damage in the homozygous knockout mouse splenocytes than in the splenocytes from the wild-type or heterozygous mice. These findings suggest that superoxide is involved either directly or indirectly in producing DNA damage in cells exposed to trivalent methylated arsenicals. These arsenicals may generate reactive oxygen species that damage DNA. This DNA damage may be a key factor in initiating cancer in vivo. Environ. Mol. Mutagen., 2011. Published 2010 Wiley-Liss, Inc.

Because the general problem of transport can be decomposed into two problems, a boundary-value problem and an initial-value problem, the complete solution is a superposition of the solutions for these two problems. In this paper, the solution for the general problem is explained. A direct application of the solution for the boundary-value problem is dye-tracing experiments. The purpose is inclusion of the input history of a solute dye into the ADM. The measured breakthrough curve of a dye-tracing experiment is used to invert for the release history of the dye at the input point through the ADM. It is mathematically shown that the breakthrough curve can not be directly used to invert for the boundary condition at a tracer release point. Therefore, a conductance-fitting method is employed to obtain the input history. The inverted history for a simple example is then shown to be a step function with amplitude of 420 mu g/L and a duration of 10 minutes. Simulations illustrate that the breakthrough curves at downstream springs provide a means for understanding the migration of dye. A discussion of the implication of the solution for an initial-value problem (e.g., simulating transport of preexisting solutes such as dissolved calcium carbonate in solution conduits) is also included.

The demand for corn ethanol is likely to cause a shift toward greater corn planting. To be prepared for the potential impacts of increased corn production, we need a better understanding of the current state of ecosystem services in this region. In this article, we describe a unique procedure for developing a dataset containing multiple variables useful in modeling ecological responses and tradeoffs. We demonstrate how to construct a detailed land cover classification and link it to yield and agricultural practices. We used the 2001 National Land Cover Database (NLCD) to spatially constrain the datasets during overlay analysis. With this method, we found that the percent agreement between classifications was frequently greater than 80%, indicating little change to the original base layer accuracies. Using three different land cover datasets, we were able to add 18 classes for agriculture and 155 classes for natural cover. We then linked variables for yield, fertilizer, and pesticide application rates, field residue, irrigation percentages, and tillage practices to the land cover data. The final Midwest dataset contained 15.5 million grid values and 15 variables. Capturing the land cover and land management information at the 30-m grid scale allows for aggregation and modeling of the ecosystem services at a variety of spatial scales. As a final step, we demonstrate a tradeoff evaluation between corn yield and nitrogen loadings using our dataset. The effort required to develop the Midwest dataset was greater than initially anticipated; however, the benefit of being able to calculate derivative variables and add new variables justifies the time expenditure needed to create such a detailed database.

In this study, we investigated the role of a mechanical disturbance that has been used to restore and maintain local wetland diversity after a monotypic regime shift in northwestern Costa Rica [specifically, an abrupt landscape-scale cattail (Typha) expansion]. The study was conducted in Palo Verde Marsh (Palo Verde National Park; a RAMSAR Wetland of International Importance), a seasonally flooded freshwater wetland that has historically provided habitat for large populations of wading birds and waterfowl. A cattail (T. domingensis) expansion in the 1980s greatly altered the plant community and reduced avian habitat. Since then, Typha has been managed using a form of mechanical disturbance called fangueo (a Spanish word, pronounced "fahn-gay-yo" in English). We applied a Typha removal treatment at three levels (control, fangueo, and fangueo with fencing to exclude cattle grazing). Fangueo resulted in a large reduction in Typha dominance (i.e., decreased aboveground biomass, ramet density, and ramet height) and an increase in habitat heterogeneity. As in many ecosystems that have been defined by multiple and frequent disturbances, a large portion of the plant community regenerated after disturbance (via propagule banking) and fangueo resulted in a more diverse plant community that was strongly dictated by seasonal processes (i.e., distinct wet- and dry-season assemblages). Importantly, the mechanical disturbance had no apparent short-term impact on any of the soil properties we measured (including bulk density). Interestingly, low soil and foliar N:P values indicate that Palo Verde Marsh and other wetlands in the region may be nitrogen limited. Our results quantify how, in a cultural landscape where the historical disturbance regime has been altered and diversity has declined, a mechanical disturbance in combination with seasonal drought and flooding has been used to locally restrict a clonal monodominant plant expansion, create habitat heterogeneity, and maintain plant diversity.

Therefore, managers increasingly need better economic data to help them prioritize their management strategies and distribute their increasingly limited resources to those strategies. Despite frequent pronouncements about the substantial ecological and economic impacts of invasive species, there have been few if any rigorous analyses of the economic impacts of invasive species in coastal systems. Here we present a bioeconomic analysis of the impacts of the European green crab, Carcinus maenas, on commercial shellfisheries along the West Coast of the United States. Green crabs are among the most comprehensively studied and widely distributed invasive species in coastal systems, with established populations on every continent except Antarctica. Their impacts on commercial bivalve fisheries have been alleged or substantiated to varying degrees, but no formal analysis of the economic impacts of the green crab has been conducted. We assess economic impacts using a combination of ecological and economic models. The ecological models incorporate green crab dispersal and description of estuarine habitat and the relationship between green crab abundance and predation on prey populations. The economic analysis focuses on the green crab impacts on commercial shellfisheries, including both historical and present impacts of green crabs on several important shellfisheries, including soft-shell clams, blue mussels, scallops, hard-shell clams, and Manila clams. We conclude that the past and present economic impacts on the West Coast shellfisheries are minor, although losses could increase significantly if densities increase or with northward range expansion into Alaska.

CYN has been responsible for both livestock and human poisoning after oral exposure. This study investigated the toxicity of CYN to pregnant mice exposed during different segments of gestation. The course of recovery and individual responses to the toxin were evaluated. Adverse effects of CYN were monitored up to 7 weeks post-dosing by clinical examination, histopathology, biochemistry and gene expression. Exposure on gestational days (GD) 8-12 induced significantly more lethality than GD13-17 exposure. Periorbital, gastrointestinal and distal tail hemorrhages were seen in both groups. Serum markers indicative of hepatic injury (alanine amino transferase, aspartate amino transferase and sorbitol dehydrogenase) were increased in both groups; markers of renal dysfunction (blood urea nitrogen and creatinine) were elevated in the GD8-12 animals. Histopathology was observed in the liver (centrilobular necrosis) and kidney (interstitial inflammation) in groups exhibiting abnormal serum markers. The expression profiles of genes involved in ribosomal biogenesis, xenobiotic and lipid metabolism, inflammatory response and oxidative stress were altered 24 h after the final dose. One week after dosing, gross, histological and serum parameters had returned to normal, although increased liver/body weight ratio and one instance of gastrointestinal bleeding was found in the GD13-17 group. Gene expression changes persisted up to 2 weeks post-dosing and returned to normal by 4 weeks. Responses of individual animals to CYN exposure indicated highly significant inter-animal variability within the treated groups.

Here, we use high-resolution, remotely-sensed land cover, imperviousness, and tree canopy density data to calculate modified Soil Conservation Service (SCS) composite curve numbers. Policy makers can interpret composite curve numbers as a continuous, relative index of storm water mitigation ecosystem services provided by the landscape, allowing for better comprehension of the implications of land use decisions than current discrete methods. We also compare composite curve number calculations from regional land cover/land use data to calculations from national land cover data and show that they differ significantly in each of the watersheds that drain into Tampa Bay. The use of discrete urban classes to determine curve numbers is also explored. We show that, for the Tampa Bay region, assumed urban imperviousness values published in Technical Release 55 (a document that provides curve numbers for soil/land cover complexes) overestimate the actual imperviousness as reported by the national and regional datasets. This error in estimation caused composite curve numbers calculated using remotely-sensed data to be lower than they would have been if curve numbers had been assigned solely by discrete SCS classes. Furthermore, the average imperviousness for all urban classes increased from 1995 to 2005, reflecting region-wide increases in imperviousness reported by the regional dataset. Our comparison illustrates that using a constant imperviousness value for urban classes over time, a method used in numerous studies and models, leads to inaccurate estimation of temporal changes in storm water runoff. Average imperviousness for urban classes also differed significantly between the regional and national datasets, signifying that the two datasets cannot be used interchangeably.

The waterbody was assumed to be impacted with a mixture of secondary-treated disinfected municipal wastewater and untreated (or poorly treated) sewage, using Norovirus as the reference pathogen and enterococci as the reference faecal indicator. The contribution made by each source to the total waterbody volume, indicator density, pathogen density, and illness risk was estimated for a number of scenarios that accounted for pathogen and indicator inactivation based on the age of the effluent (source-to-receptor), possible sedimentation of microorganisms, and the addition of a non-pathogenic source of faecal indicators (such as old sediments or an animal population with low occurrence of human-infectious pathogens). The waterbody indicator density was held constant at 35CFU 100mL super(-1) enterococci to compare results across scenarios. For the combinations evaluated, either the untreated sewage or the non-pathogenic source of faecal indicators dominated the recreational waterbody enterococci density assuming a culture method. In contrast, indicator density assayed by qPCR, pathogen density, and bather gastrointestinal illness risks were largely dominated by secondary disinfected municipal wastewater, with untreated sewage being increasingly less important as the faecal indicator load increased from a non-pathogenic source. The results support the use of a calibrated qPCR total enterococci indicator, compared to a culture-based assay, to index infectious human enteric viruses released in treated human wastewater, and illustrate that the source contributing the majority of risk in a mixture may be overlooked when only assessing faecal indicators by a culture-based method. Highlightsao Ingestion of human-impacted water with a faecal indicator density at the recreational water quality limit resulted in a range of GI risk using QMRA. ao When GI risk was set at 0.03, secondary-treated disinfected municipal wastewater effluent was the major waterbody contaminant by volume. ao Enterococci assayed by culture was contributed mostly by untreated sewage or non-pathogenic faecal indicator sources. ao Whereas, enterococci estimated by qPCR was contributed by secondary-treated disinfected municipal wastewater effluent or non-pathogenic faecal indicator sources. ao Norovirus genome density and GI risk were contributed by a combination of untreated sewage and secondary-treated disinfected municipal wastewater effluent.

This article presents an alternate approach of modeling soil and dust ingestion via hand and object mouthing of children, using EPA's SHEDS model. Results for children 3 to <6 years old show that mean and 95th percentile total ingestion of soil and dust values are 68 and 224 mg/day, respectively; mean from soil ingestion, hand-to-mouth dust ingestion, and object-to-mouth dust ingestion are 41 mg/day, 20 mg/day, and 7 mg/day, respectively. In general, hand-to-mouth soil ingestion was the most important pathway, followed by hand-to-mouth dust ingestion, then object-to-mouth dust ingestion. The variability results are most sensitive to inputs on surface loadings, soil-skin adherence, hand mouthing frequency, and hand washing frequency. The predicted total soil and dust ingestion fits a lognormal distribution with geometric mean = 35.7 and geometric standard deviation = 3.3. There are two uncertainty distributions, one below the 20th percentile and the other above. Modeled uncertainties ranged within a factor of 3-30. Mean modeled estimates for soil and dust ingestion are consistent with past information but lower than the central values recommended in the 2008 EPA Child-Specific Exposure Factors Handbook. This new modeling approach, which predicts soil and dust ingestion by pathway, source type, population group, geographic location, and other factors, offers a better characterization of exposures relevant to health risk assessments as compared to using a single value.

Mycobacterium bovis causes tuberculosis in humans and several animal species. Peracetic acid is an approved tuberculocide in hospital and domestic environments. This study presents for the first time the transcriptomic changes in M. bovis BCG after treatment with 0.1mM peracetic acid for 10 and 20min. This study also presents for the first time a comparison among the transcriptomic responses of M. bovis BCG to three oxidative disinfectants: peracetic acid, sodium hypochlorite, and hydrogen peroxide after 10min of treatment. Results indicate that arginine biosynthesis, virulence, and oxidative stress response genes were upregulated after both peracetic acid treatment times. Three DNA repair genes were downregulated after 10 and 20min and cell wall component genes were upregulated after 20min. The devR-devS signal transduction system was upregulated after 10min, suggesting a role in the protection against peracetic acid treatment. Results also suggest that peracetic acid and sodium hypochlorite both induce the expression of the ctpF gene which is upregulated in hypoxic environments. Further, this study reveals that in M. bovis BCG, hydrogen peroxide and peracetic acid both induce the expression of katG involved in oxidative stress response and the mbtD and mbtI genes involved in iron regulation/virulence.

AN - 860397261; 21267611 AB - Human exposure to gadolinium-based contrast agents can be complicated by nephrogenic systemic fibrosis (NSF). Demonstration of significant quantities of insoluble gadolinium in the skin of NSF patients suggested transmetallation as a mechanism of toxicity of this injury. An alternative pathway for the biological effect of gadolinium is a disruption of iron homeostasis. We tested the postulate that cell exposure to gadolinium increases iron uptake to disrupt intracellular metal homeostasis and impact inflammatory events. Alveolar macrophages, THP1 cells, NHBE cells, and BEAS-2B cells all demonstrated a capacity to import gadolinium from both GdCl(3) and Omniscan. All four cell types similarly imported iron following exposure to ferric ammonium citrate (FAC). Exposure of all cell types to gadolinium and iron resulted in increased iron import relative to cell concentrations following incubation with FAC alone. To analyze for further evidence of changes in iron homeostasis, cell ferritin concentration was determined. Relative to incubation with FAC alone, co-incubation of BEAS-2B cells with gadolinium and FAC resulted in significant increases in ferritin level. Finally, potential effects of gadolinium uptake and associated changes in iron homeostasis on the inflammatory response were evaluated by measuring IL-8. Co-incubation of BEAS-2B cells with both gadolinium and iron resulted in diminished release of IL-8 relative to levels of the cytokine following incubation with gadolinium alone. We conclude that gadolinium impacts cell iron homeostasis to change import and storage of the metal and biological effects of exposure.

AN - 859495814; 21361318 AB - Certain endocrine-active toxicants have been reported to completely sex reverse both male and female individuals in amphibian, avian, fish, invertebrate, and reptile species, resulting in a phenotype indistinguishable from unaffected individuals. Detection of low-level sex reversal often requires large numbers of organisms to achieve the necessary statistical power, especially in those species with predominantly genetic sex determination and cryptic/homomorphic sex chromosomes. Here we describe a method for determining the genetic sex in the commonly used ecotoxicological model, the fathead minnow (Pimephales promelas). Analysis of amplified fragment length polymorphisms (AFLP) in a spawn of minnows resulted in detection of 10 sex-linked AFLPs, which were isolated and sequenced. No recombination events were observed with any sex-linked AFLP in the animals examined (n=112). A polymerase chain reaction (PCR) method was then developed that determined the presence of one of these sex-linked polymorphisms for utilization in routine toxicological testing. Analyses of additional spawns from our in-house culture indicate that fathead minnows utilize a XY sex determination strategy and confirm that these markers can be used to genotype sex; however, this method is currently limited to use in laboratory studies in which breeders possess a defined genetic makeup. The genotyping method described herein can be incorporated into endocrine toxicity assays that examine the effects of chemicals on gonad differentiation.

AN - 858289908; 21278054 AB - Propiconazole is a mouse hepatotumorigenic fungicide and has been the subject of recent investigations into its carcinogenic mechanism of action. The goals of this study were (1) to identify metabolomic changes induced in the liver by increasing doses of propiconazole in mice, (2) to interpret these results with key previously reported biochemical, transcriptomic, and proteomic findings obtained from mouse liver under the same treatment conditions, and (3) to relate these alterations to those associated with the carcinogenesis process. Propiconazole was administered to male CD-1 mice in the feed for 4 days with six mice per feed level (500, 1250, and 2500 ppm). The 2500 ppm dose level had previously been shown to induce both adenocarcinomas and adenomas in mouse liver after a 2-year continuous feed regimen. Endogenous biochemicals were profiled using liquid chromatography/mass spectrometry and gas chromatography/mass spectrometry methods and 261 were detected. The most populous biochemical class detected was lipids, followed by amino acids and then carbohydrates. Nucleotides, cofactors and vitamins, energy, peptides, and xenobiotics were also represented. Of the biochemicals detected, 159 were significantly altered by at least one dose of propiconazole and many showed strong dose responses. Many alterations in the levels of biochemicals were found in the glycogen metabolism, glycolysis, lipolysis, carnitine, and the tricarboxylic acid cycle pathways Several groups of metabolomic responses were ascribed to the metabolism and clearance of propiconazole: glucuronate, glutathione, and cysteine pathways. Groups of metabolic responses supported previous hypotheses on key events that can lead to propiconazole-induced tumorigenesis: oxidative stress and increases in the cholesterol biosynthesis pathway. Groups of metabolomic responses identified biomarkers associated with neoplasia: increases in glycolysis and increases in the levels of spermidine, sarcosine, and pseudouridine.

AN - 858288691; 21422872 AB - The obesity epidemic, including a marked increase in the prevalence of obesity among pregnant women, represents a critical public health problem in the United States and throughout the world. Over the past two decades, it has been increasingly recognized that the risk of adult health disorders, particularly metabolic syndrome, can be markedly influenced by prenatal and infant environmental exposures (ie, developmental programming). Low birth weight, together with infant catch-up growth, is associated with a significant risk of adult obesity and cardiovascular disease, as well as adverse effects on pulmonary, renal, and cerebral function. Conversely, exposure to maternal obesity or high birth weight also represents an increased risk for childhood and adult obesity. In addition, fetal exposure to select chemicals (eg, phytoestrogens) or environmental pollutants (eg, tobacco smoke) may affect the predisposition to adult disease. Animal models have confirmed human epidemiologic findings and provided insight into putative programming mechanisms, including altered organ development, cellular signaling responses, and epigenetic modifications (ie, control of gene expression without modification of DNA sequence). Prenatal care is transitioning to incorporate goals of optimizing maternal, fetal, and neonatal health to prevent or reduce adult-onset diseases. Guidelines regarding optimal pregnancy nutrition and weight gain, management of low- and high-fetal-weight pregnancies, use of maternal glucocorticoids, and newborn feeding strategies, among others, have yet to fully integrate long-term consequences on adult health.

AN - 855910271; 21191878 AB - Water quality and toxic exposure science is transitioning towards analysis of multiple stressors rather than one particular environmental concern (e.g., mercury) or a group of similarly reacting chemicals (e.g., nutrients). However, two of the most important water quality constituents affecting both human and ecosystem health today, reactive nitrogen (N(r) ) and methylmercury (MeHg), are often assessed separately for their independent effects on water quality. With the continued pressure of landscape modifications on water quality, a challenge remains in understanding the concurrent watershed flux response of both N(r) and MeHg to such physical stressors, particularly at the spatial scale (regional watersheds) and within the mixed land cover type systems that most decision-making processes are conducted. We simulate the annual average and monthly flux responses of Hg (MeHg and total mercury [HgT]), NO(3) -N, and runoff to four land cover change scenarios in the Haw River Watershed (NC, USA), a headwater system in the Cape Fear River Basin. Fluxes are simulated using a process-based, spatially explicit watershed Grid-Based Mercury Model (GBMM) and a NO(3) -N watershed flux model we developed to link to GBMM. Results suggest that annual NO(3) -N and Hg fluxes increase and decrease concomitantly to land cover change; however, the magnitude of the changes in NO(3) -N, MeHg, HgT, and water fluxes vary considerably between different land cover conversion scenarios. Converting pasture land to a suburbanized landscape elicited the greatest increase in runoff and MeHg, HgT, and NO(3) -N fluxes among all four conversion scenarios. Our findings provide insight for multi-stressor ecological exposure research and management of coastal eutrophication resulting from elevated N(r) loadings and exposure risk due to elevated concentrations of MeHg in fish tissue.

AN - 855908662; 21194177 AB - Supercritical fluid extraction (SFE) with pure CO(2) was assessed as a confirmatory tool in phase III of whole sediment toxicity identification evaluations (TIEs). The SFE procedure was assessed on two reference sediments and three contaminated sediments by using a combination of toxicological and chemical measurements to quantify effectiveness. Sediment toxicity pre- and post-SFE treatment was quantified with a marine amphipod (Ampelisca abdita) and mysid (Americamysis bahia), and nonionic organic contaminants (NOCs) polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) were measured in sediments, overlying waters, and interstitial waters. In general, use of SFE with the reference sediments was successful, with survival averaging 91% in post-SFE treatments. Substantial toxicity reductions and contaminant removal from sediments and water samples generated from extracted sediments of up to 99% in two of the contaminated sediments demonstrated SFE effectiveness. Furthermore, toxicological responses for these SFE-treated sediments showed comparable results to those from the same sediments treated with the powdered coconut charcoal addition manipulation. These data demonstrated the utility of SFE in phase III of a whole sediment TIE. Conversely, in one of the contaminated sediments, the SFE treatments had no effect on sediment toxicity, whereas sediment concentrations of PCBs and PAHs were reduced. We propose that, for some sediments, the SFE treatment may result in the release of otherwise nonbioavailable cationic metals that subsequently cause toxicity to test organisms. Overall, SFE treatment was found to be effective for reducing the toxicity and concentrations of NOCs in some contaminated sediments. However, these studies suggest that SFE treatment may enhance toxicity with some sediments, indicating that care must be taken when applying SFE and interpreting the results. Copyright © 2011 SETAC.

AN - 855200108; 20514482 AB - Our earlier findings indicate that (1) peregrine falcons (Falco peregrinus anatum Bonaparte) nesting in major California cities have among the highest polybrominated diphenyl ether (PBDE) levels in the world (max ∑PBDEs=100 ppm), and (2) Big City peregrines have higher levels and proportions of the higher-brominated congeners (hepta- to deca-BDEs) than do their Coastal counterparts. In this study we classified the prey species (n =185) from the remains of prey (feathers) at 38 peregrine nest sites over 25 years (1974-1998). We grouped the prey species into 15 categories based on diet and found distinctly different prey patterns for Big City vs. Coastal peregrines. Big City peregrines had a higher (almost three times) weight percentage intake of food waste-eating birds (e.g., rock pigeons, Columba livia) than Coastal peregrines. These differing prey patterns suggest diet as a potential source of the unusually high levels and proportions of higher-brominated PBDEs in Big City peregrines. The relative contributions of diet and dust (e.g., preening) exposure to PBDE patterns in Big City peregrines will be explored in future investigations. © Springer Science+Business Media, LLC 2010 JF - Archives of environmental contamination and toxicology AU - Park, June-Soo AU - Fong, Alison AU - Chu, Vivian AU - Holden, Arthur AU - Linthicum, Janet AU - Hooper, Kim AD - Environmental Chemistry Laboratory, Department of Toxic Substances Control, California Environmental Protection Agency, Berkeley, CA 94710, USA. jpark@dtsc.ca.gov Y1 - 2011/04// PY - 2011 DA - April 2011 SP - 518 EP - 523 VL - 60 IS - 3 KW - Environmental Pollutants KW - 0 KW - Halogenated Diphenyl Ethers KW - Index Medicus KW - Environmental Monitoring KW - California KW - Ovum -- chemistry KW - Cities KW - Animals KW - Birds -- classification KW - Species Specificity KW - Male KW - Female KW - Diet -- veterinary KW - Food Chain KW - Halogenated Diphenyl Ethers -- analysis KW - Environmental Pollutants -- analysis KW - Falconiformes -- metabolism UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/855200108?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=Archives+of+environmental+contamination+and+toxicology&rft.atitle=Prey+species+as+possible+sources+of+PBDE+exposures+for+peregrine+falcons+%28Falco+peregrinus%29+nesting+in+major+California+cities.&rft.au=Park%2C+June-Soo%3BFong%2C+Alison%3BChu%2C+Vivian%3BHolden%2C+Arthur%3BLinthicum%2C+Janet%3BHooper%2C+Kim&rft.aulast=Park&rft.aufirst=June-Soo&rft.date=2011-04-01&rft.volume=60&rft.issue=3&rft.spage=518&rft.isbn=&rft.btitle=&rft.title=Archives+of+environmental+contamination+and+toxicology&rft.issn=1432-0703&rft_id=info:doi/10.1007%2Fs00244-010-9546-x LA - English DB - ProQuest Environmental Science Collection N1 - Date completed - 2011-07-21 N1 - Date created - 2011-03-03 N1 - Date revised - 2017-01-13 N1 - Last updated - 2017-01-18 DO - http://dx.doi.org/10.1007/s00244-010-9546-x ER - TY - JOUR T1 - Toxicity of ammonia to surf clam (Spisula solidissima) larvae in saltwater and sediment elutriates. AN - 854378838; 21295341 AB - Ammonia is a natural component of sediments and has been identified as a common contributor to toxicity in marine sediment, elutriate and porewater testing. In our study, the role of ammonia as a possible toxicant in sediment toxicity tests was evaluated using larvae of the surf clam, Spisula solidissima. Elutriates were prepared and tested using six baseline sediment samples. Ammonia was then purged from aliquots of the baseline sediment samples prior to elutriate preparation. Finally, ammonia was spiked into aliquots of the purged elutriates to mimic ammonia concentrations measured in the baseline elutriates. Toxicity was present in all of the baseline samples and was removed in the ammonia purged samples. In most cases, toxicity was comparable in the ammonia spiked samples to levels measured in the baseline samples. Water only toxicity tests revealed that larvae of the surf clam are one of the more ammonia sensitive marine species. The LC50 for survival was 10.6 mg/L total ammonia (.53 mg/L unionized ammonia) and the EC50 for shell development was 2.35 mg/L total ammonia (.12 mg/L unionized ammonia). Toxicity endpoints calculated from the water only ammonia toxicity test were good predictors of effects observed in the sediment elutriate tests. Published by Elsevier Ltd.

AN - 851749820; 21314472 AB - Polybrominated diphenyl ethers (PBDEs) are commonly used as commercial flame retardants in a variety of products, including plastics and textiles. Previous studies in our laboratory, and in the literature, showed that exposure to a specific PBDE congener (PBDE 47) during a critical period of brain development may lead to developmental delays and hyperactivity in adulthood. To date, the underlying causes of these behavioral alterations are unknown, although in vitro studies linked PBDEs with potential alterations in neurotransmitter levels, particularly acetylcholine (ACh) and dopamine (DA). Alterations in DA function have also been noted in cases of hyperactivity in rodents and humans. The current study examined monoamine levels in male mice acutely exposed to corn oil vehicle or PBDE 47 (1, 10, or 30 mg/kg) on postnatal day (PND) 10. Animals were sacrificed on PND 15, PND 20, and in adulthood (131-159 days old). The cortex, striatum, and cerebellum were isolated and analyzed by high-performance liquid chromatography to determine the concentration of monoamines within each brain region. A statistically significant increase in DA levels was seen within the cortex, regardless of age, but only in the 10-mg/kg PBDE treatment group. While these effects did not show a monotonic dose response, we previously reported hyperactivity in littermates in the same dose group, but not at the lower or higher dose. Thus, early developmental exposure to PBDE 47 alters the levels of cortical DA in male mice, which may correlate with behavioral observations in littermates.

AMET was first developed to evaluate the performance of the 5th Generation Mesoscale Model (MM5) and the Weather Research and Forecasting (WRF) meteorological model output and was later extended to include capabilities for evaluating output data from the Community Multiscale Air Quality (CMAQ) model as well. AMET is designed to leverage several open-source software packages that are used in combination to 1) pair the modeled and observed values in time and space, 2) store these paired datasets in an easily accessible and searchable database and 3) access and analyze these data using a statistical package. Through this process, AMET is able to provide a convenient method for evaluating meteorological and air quality model predictions. The use of a searchable, relational database allows the entire dataset to be quickly subset into only those data that are of the most interest for the current analysis, a process that is often tedious and time consuming without the use of a database. In addition to common summary statistics (e.g. RMSE, bias, and correlation), several of the many analysis features available in AMET include scatter plots, time series plots, box plot and spatial plots as part of operational model evaluation. Additionally, several unique analysis functions are also available in AMET, and the system provides a framework within which users may extend the current functionality for their own custom analyses.

Aqueous fullerene suspensions were formed by stirring C sub(60) and C sub(70) as received from a commercial vendor in deionized water (termed aqu/C sub(60) and aqu/C sub(70)) for approximately 100 d. The Z-average (mean hydrodynamic) diameters of aqu/C sub(60) and aqu/C sub(70) aggregates as measured by dynamic light scattering were 517 +/- 21 nm and 656 +/- 39 nm (mean +/- 95% confidence limit), respectively. Exposure of T. platyurus to fullerene suspensions resulted in the formation of dark masses in the digestive track visible under a stereo microscope (x40 magnification). Fullerene ingestion over 1 h of exposure was quantitatively determined after extraction and analysis by high-performance liquid chromatography-mass spectrometry (HPLC-MS). One-hour exposures (at 3 mg/L and 6 mg/L) resulted in aqu/C sub(60) burdens of 2.7 +/- 0.4 mu g/mg and 6.8 +/- 1.5 mu g/mg wet weight, respectively. Thin-section transmission electron microscopy (TEM) images of aqu/C sub(60)-exposed T. platyurus showed the formation in the gut of fullerene agglomerates (5-10 mu m) that were an order of magnitude larger than the suspended fullerene agglomerates. Upon excretion, the observed fullerene agglomerates were in the 10- to 70- mu m size range and settled to the bottom of the incubation wells. In contrast to the control polystyrene microspheres, which dispersed after depuration, the aqu/C sub(60) agglomerates (greater than two orders of magnitude larger than the suspended fullerenes) remained agglomerated for up to six months. When exposed to fullerenes, T. platyurus shows the potential to influence agglomerate size and may facilitate movement of these nanoparticles from the water column into sediment.

Our new methodology addresses common pitfalls of multiple regression including measurement uncertainty, colinearity of covariates, dataset selection, and model selection. As expected, summertime OM/OC ratios are larger than wintertime values across the US with all regional median OM/OC values tightly confined between 1.80 and 1.95. Further, we find that OM/OC ratios during the winter are distinctly larger in the eastern US than in the West (regional medians are 1.58, 1.64, and 1.85 in the great lakes, southeast, and northeast regions, versus 1.29 and 1.32 in the western and central states). We find less spatial variability in long-term averaged OM/OC ratios across the US (90% of our multiyear regressions estimate OM/OC ratios between 1.37 and 1.94) than previous studies (90% fell between 1.30 and 2.10). We attribute this difference largely to the inclusion of EC as a covariate in previous regression studies. Due to the colinearity of EC and OC, we find that up to one-quarter of the OM/OC estimates in a previous study are biased low. Assumptions about OC measurement artifacts add uncertainty to our estimates of OM/OC. In addition to estimating OM/OC ratios, our technique reveals trends that may be contrasted with conventional assumptions regarding nitrate, sulfate, and soil across the IMPROVE network. For example, our regressions show pronounced seasonal and spatial variability in both nitrate volatilization and sulfate neutralization and hydration.

Wetlands in urban landscapes provide nesting opportunities for wetland breeding birds as well as enhanced food resources that may be utilized by opportunistic species and those that can tolerate human activity. We investigated the degree to which birds utilize urban wetlands by examining breeding bird communities in urban and rural wetlands and nearby uplands in the northeast US. From mid-May through June in 2008, we conducted 10-min, 50m radius point counts at 99 randomly chosen sites along a gradient of watershed urbanization. Bird abundance and species richness was significantly higher in wetlands versus uplands, and at urban wetlands versus urban uplands, but not at rural wetlands versus rural uplands. Overall, more species were present at wetland versus upland sites, but the difference between wetland and upland was less for human-tolerant species. While the amount of natural vegetation within a 50m buffer of a site was significantly negatively correlated with the amount of urban land within 1km, bird abundance and species richness increased. Species-specific habitat models using general vegetation classes showed differences in bird habitat associations as watersheds became more urbanized. Our findings demonstrate the importance of wetland habitats for birds, and add to the body of evidence that supports the protection and restoration of wetlands as a means towards maintaining or enhancing habitat heterogeneity and biodiversity in urban landscapes.

The present study is a performance evaluation and critical analysis of assay results for an array of 292 high-throughput cell-free assays aimed at preliminary toxicity evaluation of 320 environmental chemicals in EPA's ToxCast(TM) project (Phase I). The chemicals (309 unique, 11 replicates) were mainly precursors or the active agent of commercial pesticides, for which a wealth of in vivo toxicity data is available. Biochemical HTS (high-throughput screening) profiled cell and tissue extracts using semi-automated biochemical and pharmacological methodologies to evaluate a subset of G-protein coupled receptors (GPCRs), CYP450 enzymes (CYPs), kinases, phosphatases, proteases, HDACs, nuclear receptors, ion channels, and transporters. The primary screen tested all chemicals at a relatively high concentration 25 mu M concentration (or 10 mu M for CYP assays), and a secondary screen re-tested 9132 chemical-assay pairs in 8-point concentration series from 0.023 to 50 mu M (or 0.009-20 mu M for CYPs). Mapping relationships across 93,440 chemical-assay pairs based on half-maximal activity concentration (AC50) revealed both known and novel targets in signaling and metabolic pathways.

The present study compared the pharmacokinetic properties of PFNA in two laboratory rodent species. Male and female Sprague-Dawley rats were given a single dose of PFNA by oral gavage at 1, 3, or 10mg/kg, and blood was collected from the tail vein at 1, 2, 3, 4, 7, 16, 21, 28, 35, 42 and 50 days after treatment. In addition, livers and kidneys were collected for PFNA analysis at the terminal time point. CD-1 mice were given a single oral dose of PFNA of 1 or 10mg/kg, and 4 males and 4 females were killed at similar time intervals; trunk blood, liver and kidney were collected. Serum and tissue concentrations of PFNA were determined by LC-MS/MS. Serum elimination of PFNA is by and large linear with exposure doses in the rat; however, like PFOA, a major sex difference in the rate of elimination is observed, with an estimated half-life of 30.6 days for males and 1.4 days for females. PFNA is stored preferentially in the liver but not in the kidneys. In the mouse, the rates of PFNA serum elimination are non-linear with exposure dose and are slightly faster in females than males, with terminal estimated serum half-life of 25.8-68.4 days and 34.3-68.9 days, respectively. PFNA is also stored preferentially in the mouse liver but not in the kidneys. Hepatic uptake appears to be more efficient and storage capacity greater in male mice than in females. These data suggest that (1) PFNA is more persistent in the mouse than in the rat; (2) there is a major sex difference in the serum elimination of PFNA in the rat, but much less so in the mouse; and (3) there is a significantly higher hepatic accumulation of PFNA in male mice than in females.

The diversity of that evidence creates complexities that can be managed using an explicit, well-designed process. We suggest two adaptations from the legal lexicon, weight of evidence and building a case. When weighing evidence, weights are assigned to each piece of evidence, and then the body of evidence is weighed in favor of each hypothesis by amassing the weights. Finally, the total weights of evidence for the alternative hypotheses are compared to determine which alternative has the preponderance of evidence in its favor. When building a case, pieces of evidence are organized to show relationships among multiple hypotheses or complex interactions among agents, events, or processes. We provide processes for weighing evidence and building a case and illustrate both approaches in a case study involving the decline of a kit fox population. The general approach presented here is flexible, transparent, and defensible. During its development, it has been applied to risk assessments for contaminated sites and to causal assessments in aquatic and terrestrial systems. It is intended to balance the need for rigor and discipline with the need for sufficient flexibility to accept all relevant evidence and generate creative solutions to difficult environmental problems.

When coupled with image analysis software, the usefulness of digital cameras can be increased to advance the field of micropedology. The determination of a representative elementary area (REA) still remains a critical information need for soil scientists so that field measurements are independent of sample size and account for spatial heterogeneity. An objective of this study was to define and determine an REA for Low Chroma and High Chroma soil redoximorphic features (SRFs) present in claypan soils of northeastern Missouri, USA using a digital camera and image classification techniques. An additional objective was to examine REA differences between these two SRF types, soil depths, and landscape positions to highlight sampling considerations when quantifying SRFs in the field. Three metrics were chosen to quantify SRF heterogeneity, including percent occurrence, mean Euclidean distance, and the Interspersion/Juxtaposition Index. The relative change in these metrics was determined for 16 image sizes ranging from 2.5 cm[super]2 to 40 cm[super]2 and used to identify an REA. Results showed REAs (mean +/- SE) for Low Chroma (17.7 cm[super]2 +/- 0.4) and High Chroma (25.4 cm[super]2 +/- 0.7) were significantly different ( alpha = 0.05). Further review of REAs indicated large sampling diameters (> 8 cm) are necessary to simultaneously capture REAs of Low Chroma and High Chroma SRFs. When SRFs were considered separately, a >= 5 cm diameter core is recommended to reach an REA for Low Chroma, allowing accurate quantification for soil classification purposes and hydric soil determinations. Federal and state agencies requiring quantifiable SRF measures for land management decisions may greatly benefit from determining these minimum measurement scales, ensuring appropriate data collection methods in the future.

AN - 856770334; 21341686 AB - The microbial transformation of triadimefon, an agricultural fungicide of the 1,2,4-triazole class, was followed at a nominal concentration of 50 μg/mL over 4 months under aerobic conditions in three different soil types. Rates and products of transformation were measured, as well as enantiomer fractions of parent and products. The transformation was biotic and enantioselective, and in each soil the S-(+)-enantiomer reacted faster than the R-(-) one. Rates of the first-order reactions were 0.047, 0.057, and 0.107 d(-1) for the three soils. The transformation involves reduction of the prochiral ketone moiety of triadimefon to an alcohol, resulting in triadimenol, which has two chiral centers and four stereoisomers. The abundances of the four product stereoisomers were different from each other, but abundance ratios were similar for all three soil types. Triadimenol is also a fungicide; the commercial product is composed of two diastereomers of unequal amounts (ratio of about 4.3:1), each having two enantiomers of equal amounts. However, the triadimenol formed by soil transformation of triadimefon exhibited no such stereoisomer profile. Instead, different production rates were observed for each of the four triadimenol stereoisomers, resulting in all stereoisomer concentrations being different from each other and very different from concentration/abundance patterns of the commercial standard. This result is important in risk assessment if the toxicity of the environmental transformation product were to be compared to that of the commercial triadimenol. Because triadimenol stereoisomers differ in their toxicities, at least to fungi and rats, the biological activity of the triadimenol formed by microbes or other biota in soils depends on the relative abundances of its four stereoisomers. This is an exposure and risk assessment issue that, in principle, applies to any chiral pesticide and its metabolites.

AN - 851752067; 21237238 AB - A variety of chemicals, such as organophosphate (OP) and carbamate pesticides, nerve agents, and industrial chemicals, inhibit acetylcholinesterase (AChE) leading to overstimulation of the cholinergic nervous system. The resultant neurotoxicity is similar across mammalian species; however, the relative potencies of the chemicals across and within species depend in part on chemical-specific metabolic and detoxification processes. Carboxylesterases and A-esterases (paraoxonases, PON) are two enzymatic detoxification pathways that have been widely studied. We used an in vitro system to measure esterase-dependent detoxification of 15 AChE inhibitors. The target enzyme AChE served as a bioassay of inhibitor concentration following incubation with detoxifying tissue. Concentration-inhibition curves were determined for the inhibitor in the presence of buffer (no liver), rat liver plus calcium (to stimulate PONs and thereby measure both PON and carboxylesterase), and rat liver plus EGTA (to inhibit calcium-dependent PONs, measuring carboxylesterase activity). Point estimates (concentrations calculated to produce 20, 50, and 80% inhibition) were compared across conditions and served as a measure of esterase-mediated detoxification. Results with well-known inhibitors (chlorpyrifos oxon, paraoxon, methyl paraoxon, malaoxon) were in agreement with the literature, serving to support the use of this assay. Only a few other inhibitors showed slight or a trend towards detoxification via carboxylesterases or PONs (mevinphos, aldicarb, oxamyl). There was no apparent PON- or carboxylesterase-mediated detoxification of the remaining inhibitors (carbofuran, chlorfenvinphos, dicrotophos, fenamiphos, methamidophos, methomyl, monocrotophos, phosphamidon), suggesting that the influence of esterases on these chemicals is minimal. Thus, generalizations regarding these metabolic pathways may not be appropriate. As with other aspects of AChE inhibitors, their metabolic patterns appear to be chemical-specific.

We propose that 1) injury and disease following cigarette smoking are associated with exposure to and retention of particles produced during smoking and 2) the biological effects of particles associated with cigarette smoking share a single mechanism of injury with all particles. Smoking one cigarette exposes the human respiratory tract to between 15,000 and 40,000 mu g particulate matter; this is a carbonaceous product of an incomplete combustion. There are numerous human exposures to other particles, and these vary widely in composition, absolute magnitude, and size of the particle. Individuals exposed to all these particles share a common clinical presentation with a loss of pulmonary function, increased bronchial hyperresponsiveness, pathologic changes of emphysema and fibrosis, and comorbidities, including cardiovascular disease, cerebrovascular disease, peripheral vascular disease, and cancers. Mechanistically, all particle exposures produce an oxidative stress, which is associated with a series of reactions, including an activation of kinase cascades and transcription factors, release of inflammatory mediators, and apoptosis. If disease associated with cigarette smoking is recognized to be particle related, then certain aspects of the clinical presentation can be predicted; this would include worsening of pulmonary function and progression of pathological changes and comorbidity (eg, emphysema and carcinogenesis) after smoking cessation since the particle is retained in the lung and the exposure continues.

2012-034771 AB - The dynamics of organic matter (OM) deposition in lakes are influenced by environmental, climatic and anthropogenic factors and a more thorough understanding of modern sedimentation can assist in the interpretation of sediment cores. The goal of this study is to quantify seasonal OM deposition in three Maine lakes. In July 2009, funnel-type sediment traps were deployed in the deep holes of Conroy Lake (CL), Lobster Lake (LL), and Tea Pond (TP), at depths of 33.5 m, 32.3 m, and 32.9 m, respectively. Sediment traps were recovered in July 2010 and samples were frozen using dry ice in the field to preserve the OM collected. Each trap was sub-sampled at a resolution of 0.5 cm in the lab and subsequently dried at low temperature. After weighing, dry subsamples were logged for volume magnetic susceptibility. Acidified subsamples were analyzed for stable carbon isotopic ratios (delta (super 13) C), stable nitrogen isotopic ratios (delta (super 15) N), and C/N ratios using a continuous flow elemental analysis/isotope ratio mass spectrometer. The annual mass accumulation rate (MAR) of sediment from each lake was determined: CL: 7.63 mg/cm (super 2) yr, TP: 5.23 mg/cm (super 2) yr and LL: 23.0 mg/cm (super 2) yr of sediment accumulation. Organic Carbon (OC) MAR's were calculated as 1.17 mg/cm (super 2) yr at CL and 1.02 mg/cm (super 2) yr at TP. Analyses of delta (super 13) C vs. C/N data at CL and TP suggest a mix of aquatic and C3 land plant organic matter sources. delta (super 15) N for CL has a mean value of 6.26 which is much higher than TP (4.05ppm) and LL (4.48ppm). The heavier values found at CL suggest higher anthropogenic effects due to human and/or animal waste from the watershed. Seasonal variability is also noted within each record. For instance, all three lakes show seasonal variability in organic matter characteristics, likely attributed to seasonal changes in productivity. In addition, LL exhibits a shift between winter and spring in delta (super 15) N and %N values suggesting that the flooding of the western branch of the Penobscot River during the spring season loaded nutrients into the system causing an increased productivity rate.

The two main research questions addressed for this project were 1.) What relationships do varve properties at Conroy Lake, ME have with modern climate conditions; and 2.) How do the thicknesses of sedimentary laminations preserved in Conroy Lake relate to instrumental data? It is hypothesized that a correlation will be found between climate instrumental records and varve characteristics (i.e. thicknesses). Previous data from a 2009 piston core (Morissette et al. 2010) showed shifts in multiple proxies below and above 40 cm (mean below: mean above): volume magnetic susceptibility (1.3X10 (super -5) SI: 2.8X10 (super -5) SI), CaCO (sub 3) (16%: 10%), Sigma RGB (169: 159), delta (super 13) C (-33.9ppm -23.6ppm), and a stepwise shift of delta (super 15) N. Previous pollen analyses done on Conroy Lake (Gajewski, 1987) show increases of the Ambrosia and Rumex horizons at approximately 1830 AD, which can be attributed to the settlement and town incorporation of Monticello in 1846 AD. Historical accounts show that early settlers utilized the land for farming and logging. The shifts in proxies at 40cm are hypothesized to be due to land use change associated with the pollen shifts previously identified. Varve counts from this core show a statistically significant increase in lamination thicknesses between pre-settlement (mean= 0.045 cm) and post appearance (mean= 0.162 cm) (t-test= -11.4; p<<0.0001). This shift is hypothesized to also be due to changes approximately 40cm; however, due to core deformation, a significant stratigraphic interval (30.9 cm-60.5 cm) could not be counted previously. Ongoing analyses are bridging stratigraphic gaps in the record and will likely yield climatic significance. Continuous petrographic thin sections were made from three 2010 freeze cores and lamination counts are on-going. The freeze cores preserve the upper flocculent sediments in situ, and help to increase varve resolution as compared to piston cores.

The purpose of this study is to correlate paleoenvironmental indicators from both lakes, located approximately 237 km apart, through a multiple proxy analysis. The total length of sediment sections recovered at Conroy Lake was 743 cm and at Tea Pond was 683 cm. Age models created from radiocarbon dates taken from these sections have shown the basal age of the Tea Pond core to be approximately 12,547 (super 14) C years BP and Conroy Lake core to have a basal age of approximately 10,566 (super 14) C years BP. Sedimentation rates calculated from the age models show Tea Pond to have a higher average sedimentation rate. Proxies used in this study include, percent organic carbon, percent CaCO (sub 3) , dry and wet bulk densities, percent H (sub 2) O, magnetic susceptibility, delta (super 13) C, delta (super 15) N, atomic C/N ratios and percent nitrogen. Analyzing proxies within constrained ages has allowed for a regional correlation of proxy data. This study focuses on the analysis of organic matter (OM) preserved in the sedimentary record and has revealed periods of time at which there are correlations in proxy data between lakes and times at which there are not. Analyses into the source of OM through delta (super 13) C and atomic C/N ratios have shown lacustrine algae and C (sub 3) vascular plants to be the primary OM sources at both Conroy Lake and Tea Pond. Average OM percentages at Tea Pond are 38.7% and at Conroy Lake are 37.8%. Average CaCO (sub 3) percentages at Tea Pond are 13.7% and at Conroy Lake are 17.8%. The higher percent of CaCO (sub 3) at Conroy Lake can be explained by the limestone bedrock of the Carys Mills Formation. Analyses have led to the interpretation that correlations represent periods of time during which the paleoenvironmental conditions at each lake were influenced by regional climates. Correlations between OM percentages are observed from 0 - 1,500 (super 14) C years BP and at 3,700 - 5,000 (super 14) C years BP. Conversely, when correlations are not seen in this data between 1,500 - 3,700 (super 14) C years BP, the paleoenvironmental conditions may have been influenced more strongly by local environmental conditions. This study has shown correlations in paleoenvironmental proxies from Tea Pond and Conroy Lake throughout the Holocene, which provide useful data in the reconstruction of Holocene climate.

This new concrete dam replaced the Pinery Feeder Dam, an aging wooden-crib dam built in 1827. The Pinery Feeder Dam was left in-situ upstream of the new dam and was submerged within the new dam pool. Dam removal efforts along the Cuyahoga River have prompted diverse studies of each dam considered for removal, including studies of historic structures. Here we report on a geophysical investigation within the Brecksville Dam pool undertaken to ascertain and delineate the location of the historic Pinery Feeder Dam. A Geophysical Survey Systems Inc. (GSSI) ground penetrating radar (GPR) system with a 120 MHz antenna was deployed in a rubber boat. A gridwork survey of 28 tracklines was performed to provide complete coverage within the dam pool. The Pinery Feeder Dam was identified as a shallow bathymetric feature atop the flat bedrock river bottom. The dam was groundtruthed by a person physically entering the water. The GPS positions of the dam feature were plotted in ArcMap and revealed a V-shaped pattern pointing upstream. In addition, the approximate extent of the Pinery Feeder Dam was delineated and mapped out. This study demonstrates that GPR can be successfully used in river settings to map out historic structures and aid in dam removal studies.

Here, we investigate the seismic- and litho-stratigraphy of Sluice Pond, MA and reconstruct local climatic conditions. We collected sub-bottom profile data and two dated sediment cores (deep basin and margin locations) between 2007-10. Sediment proxy data include pollen and thecamoebian abundances, organic matter deposition (LOI), density, magnetic susceptibility, delta (super 13) C, delta (super 15) N, and C/N ratios. The lower portion of the basin core reveals a time of cold/dry climate from ca. 11,500 - 8,000 cal BP. Evidence includes Picea and Pinus pollen zones, geophysical reflectors that pinch out at depths <18m, generally low organic matter preservation, and a lack of sedimentation in the margin core. An increase in regional temperature/moisture is apparent in sediments younger than 8,000 cal BP. Pollen data indicate the establishment of a mixed forest ecosystem. Organic matter deposition reaches a maximum in the basin core, and the initiation of gyttja deposition in the margin sediment core at 7,800 cal BP confirms a lake level increase. A warm/dry climate is suggested from ca. 5,000 - 3,500 cal BP. This interval has been identified as the Tssuga minimum zone. During this time interval, the marginal core contains an abundance of macrophyte remains, suggesting a decrease in lake level to account for the macrophyte's affinity for the photic zone. The warm/dry period had a delayed trigger on productivity as organic matter deposition first decreased and then increased along with an increase in thecamoebian abundance at ca 4,000 cal BP. Younger sediments suggest unstressed, organic-rich conditions until the most recent sediments. The upper-most sediments record anthropogenic disturbance with increases in non-arboreal and Betula pollen, the stress-tolerant thecamoebian Difflugia protaeiformis, and a large increase in delta (super 15) N. Additionally, increases in magnetic susceptibility, trace metals, and dry bulk density, along with a relative decrease in organic matter, argue for land-use change. The climate variability interpreted from the sediments of Sluice Pond is consistent with other studies from New England, suggesting regional climatic forcings.

Its associated contaminant leachate plume is particularly noted for surprisingly high levels of arsenic concentration in the affected ground waters. Data from 15 years of monitoring and groundwater sampling show arsenic levels that occasionally exceeded 5,000 ppb of arsenic in groundwater. During summer of 2010 a comprehensive study of the landfill area included direct-push methods and roto-sonic drilling during which soil samples were obtained as well as information on the vertical profiles of groundwater. The study was conducted by the Army Corps of Engineers at 18 separate locations within and near SHL at regular 10 ft vertical intervals. Groundwater samples collected from each interval were analyzed by Ion Chromatography for major ions (Na (super +) , K (super +) , Ca (super +2) , Mg (super +2) , NH (sub 4) (super +) , Cl (super -) , NO (sub 3) (super -) , and SO (sub 4) (super -2) ), and for arsenic by Hydride Generation Atomic Fluorescence Spectrometry (HG-AFS). The results indicate in 3D the regions of elevated arsenic concentrations and more importantly provide a unique opportunity to delineate arsenic pathways in 3D space. With few exceptions, all groundwater samples from the direct-push wells located within the SHL have arsenic concentrations that are above 10 ppb (the MCL limit for As in groundwater). More striking is the vertical distribution of arsenic in groundwater within a zone that lies below the landfill bottom. This zone extends from the landfill bottom toward the basal glacial till and encompasses a lens of significantly elevated arsenic concentrations in groundwater with a strong concentration gradient toward the center and lower limit of the zone. The central zone of the lens which appears to be less than 10 ft thick yields excessively elevated arsenic concentrations (as much as and above 10,000 ppb of As in groundwater).

Individual metrics were evaluated based on relative scores on two sets of evaluation factors. A rigor score evaluated metric development based on conceptual relevance, indicator development method, degree of independent validation, and temporal and spatial extent tested. An applicability score evaluated metrics based on cost of data collection, probable spatial extent of applicability, technical complexity, and indicator responsiveness. The majority of indicators could be classified as biotic condition indicators (81%), with vegetation (37%) and macroinvertebrate (28%) metrics composing the largest proportion. Most metrics provided a conceptual model or scientific justification (97%), were developed by correlation to environmental gradients (46%), were tested over multiple seasons or years (49%) and at multiple sites (88%). Few were independently validated (18%). Average rigor score was 10 (on a scale of 0-25) and ranged between 1 and 21. Highest rigor scores were for trematode community metrics (community similarity index, species richness) and metrics of grass shrimp (Palaemonetes pugio) individuals (gene expression, relative fecundity, embryo hatching success, larval survival). Most metrics had a high cost of data collection (63%), required field and laboratory processing (84%), would be applicable across the U.S. (72%), and were responsive to the variable of interest (44%). Mean applicability score was 4.9 (range: 2-8). Highest scores were found for metrics that only required field collection of data using simple or no instrumentation. Lowest scoring metrics required expensive equipment, specialized taxonomic knowledge, complex laboratory analysis, and/or culturing of organisms. Scores for individual metrics were grouped by indicator, then averaged and rescaled between 0 and 100 to provide a composite evaluation of the indicator they measured. Among major indicator types, biotic indicators had the highest rigor scores (mean = 44, range 20-79), followed by indicators of chemical/physical characteristics (mean = 36, range 16-56), landscape condition (mean = 31, range 24-37), and hydrology/geomorphology indicators (mean = 21, range 4-52). In contrast, biotic indicators scored lowest for applicability (mean = 58, range 25-100) and indicators of landscape condition scored highest. The results of this review suggest that the development and selection of tidal wetland indicators could be vastly improved by employing a standardized development methodology that provides uniform information about each indicator. In addition, tidal wetland indicator research should focus on the development of indicators of ecological processes and disturbance regimes.

This new method uses an apparatus coupled with a metered dose inhaler to reproducibly deposit spores onto various surfaces. A metered dose inhaler was loaded with Bacillus subtilis spores, a surrogate for Bacillus anthracis. Five different material surfaces (aluminum, galvanized steel, wood, carpet, and painted wallboard paper) were tested using this spore deposition method. This aerosolization method deposited spores at a concentration of more than 107 CFU per coupon (18-mm diameter) with less than a 50% coefficient of variation, showing that the aerosolization method developed in this study can deposit reproducible numbers of spores onto various surface coupons. Scanning electron microscopy was used to probe the spore deposition patterns on test coupons. The deposition patterns observed following aerosol impaction were compared to those of liquid inoculation. A physical difference in the spore deposition patterns was observed to result from the two different methods. The spore deposition method developed in this study will help prepare spore coupons via aerosolization fast and reproducibly for bench top decontamination and detection studies.

Exposure pathways were modeled under "typical" and "contaminated" scenarios, for young children and adults. A range of intakes was also estimated from serum concentrations of PFOS reported in the National Health and Nutrition Examination Survey (NHANES) using a first-order 1-compartment PK model. Total PFOS intakes (medians summed over all pathways) were estimated as: 160 and 2200ng/day for adults and 50 and 640ng/day for children under typical and contaminated scenarios, respectively. Food ingestion appears to be the primary route of exposure in the general population. For children, the contribution from dust ingestion is nearly as great as from food ingestion. Pathway-specific contributions span several orders of magnitude and exhibit considerable overlap. PK modeling suggests central tendency PFOS intakes for adults range between 1.6 and 24.2ng/kg-bw/day, and the forward-based intake estimates are within this range. The favorable comparison reported between the forward-modeled and the back-calculated range of intake predictions lends validity to the proposed framework.

Detection of sequences targeted to the ureA gene from preparations containing 107 cells/ml decreased about 2-4 logs by days 9 and 14, respectively. When duplicate suspensions of the 107 cells/ml were exposed to higher levels of chlorine, 0.2-2.2 mg/l, by day 9 and 14 there were 5 and 6 log decreases, respectively, in the detection of ureA gene. H. pylori target sequences (within suspended, intact cells at densities of 102-103 cells /ml) were rendered undetectable by qPCR analysis after 17 h of continuous exposure to low chlorine levels common to treated drinking water distribution systems. The persistence of DNA sequences within treated distribution systems detectable by qPCR may be as brief as 17 h especially for bacteria such as H. pylori which are known to occur in very low numbers within treated distribution systems. This study suggests that degradation of H. pylori DNA target sequences by chlorine levels commonly found within treated water distribution systems occurs within the average water retention times (2-3 days) commonly found in these systems.

One rational and cost-effective method may be the implementation of increased agricultural crop diversification. Crop diversification can improve resilience in a variety of ways: by engendering a greater ability to suppress pest outbreaks and dampen pathogen transmission, which may worsen under future climate scenarios, as well as by buffering crop production from the effects of greater climate variability and extreme events. Such benefits point toward the obvious value of adopting crop diversification to improve resilience, yet adoption has been slow. Economic incentives encouraging production of a select few crops, the push for biotechnology strategies, and the belief that monocultures are more productive than diversified systems have been hindrances in promoting this strategy. However, crop diversification can be implemented in a variety of forms and at a variety of scales, allowing farmers to choose a strategy that both increases resilience and provides economic benefits.

AN - 881454231; 2011-062480 AB - Eutrophication (i.e., nutrient enrichment, organic enrichment, and oxygen depletion) is one of the most common sources of impairment in Clean Water Act 303(d)-listed waters in the United States. Although eutrophication can eventually cause adverse effects to the benthos, it may be difficult to diagnose. Sediment organic carbon (OC) content has been used as an indicator of enrichment in sediments, but the amount of surface area available for carbon adsorption must be considered. We investigated the utility of the relationship between OC and sediment grain size as an indicator of eutrophication. Data from the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program was used to test this relationship. However, anthropogenic contaminants are also capable of causing adverse effects to the benthos and often co-occur with elevated levels of OC. Contaminant analysis and toxicity tests were not consistently related to enrichment status as defined by relationship between total OC and grain size. Although variability in response occurred, reflecting the variance in the water column factors (dissolved oxygen, chlorophyll a, and nutrients) and limited sample sizes, the data supported the hypothesis that sites designated as enriched were eutrophied. Dissolved oxygen levels were reduced at enriched sites, whereas chlorophyll a and nutrients were higher at enriched sites. This suggests that the relationship of OC to grain size can be used as a screening tool to diagnose eutrophication.

Influence of these activities on transfer of pesticides from treated Formica to foods was studied. The objective was to perform simulation experiments using four foods (bread, apple slices, bologna, and sugar cookies) exposed to treated Formica after varied time intervals between surface contamination and contact (1, 6, and 24h) and frequency of contact with and without recontamination. Pesticides investigated included permethrin, bifenthrin, cyfluthrin, cypermethrin, and deltamethrin. Data will be used as input parameters for transfer efficiencies (TEs) within the Children's Dietary Intake Model (CDIM), which predicts total dietary exposure of a child. Pesticide transfer from surfaces to bologna and apples was more efficient than to bread and cookies. For the bread and cookies, all pyrethroids had a TE that ranged from below detectible levels to less than or equal to 4%. A combined average of 32-64% and 19-43% was transferred to bologna and apples, respectively, for the three contact times for all pyrethroids. The TEs of the varied time intervals indicated that increased time between contamination and contact showed little difference for bologna, bread, and cookies, but a significant difference for apples. As long as pesticide levels are measureable on surfaces in children's eating environment, it can be concluded that transfer of pesticides to foods will take place. Foods' characteristics had an important function in the transfer of pesticides when multiple contacts occurred. Regardless of recontamination, pesticides were efficiently transferred from the treated surface to bologna. The bologna did not reach a saturation point during the contacts. Pesticides were also efficiently transferred to apples, but reached a maximum TE during the second contact. The distribution of activity factors within CDIM needs to reflect the differences in the characteristics of the foods.

From 1995 to 2010 union density fell from 73,1 to 67,4 per cent, so now one third of the employees in the Danish labour market are unorganised. In contrast, only 25 per cent of employees decided to stay out of unions in 1995. In the same period, the Danish 'Commercial and Clerk Union' (HK), has lost about 15 per cent of its members and HK have reorganised its internal structure and formulated a new strategy for revitalization of the union. A research project -- organised in Carma at Aalborg University -- is evaluating the process and the results of HK's revitalisation project by looking at the work of one local union in HK: HK Ostjylland. The methodology of the research project is based on union membership theory, the classic union membership theory, the conventional demand and supply framework, theory dealing with the 'Free Rider problem' and, finally, the social custom approach to unionization. The different kinds of theory of determinants of union membership stress two motives of joining the unions: individual utility optimization, where the union is satisfying the needs of the individual -- both collective and individual needs -- and motives based on collective values, and class consciousness. It is shown that the strategy pursued by the local HK union points in quite different directions, which in part is due to the fact that the local HK union consists of four different sectors; two for the private sector and two for the public sector. Some of the strategies have inspiration from the theory of individual utility maximization and other parts of the strategies are more or less based on the classical theory of collective values and class consciousness, especially the use of the so called 'organising model'. The paper suggests that HK and the local union have no common strategy for recruiting and retaining members, but all the different strategies are relying on initiatives at the workplace level, carried out by the shop stewards in co-operation with the local union.

As we are particularly concerned with how the rise of new ethnic groups affects trust, the investigation takes place within a European context in which ethnic diversity today is primarily related to immigration from non-western countries. The data originate primarily from the World Value Study (WVS) and the first and second round of the European Social Survey. In contrast to some studies, but consistent with others, we find no general relationships between ethnic diversity, measured in terms of the size of non-western immigrants, and trust either at the country or local level after having checked for other possible sources of influence. There are, furthermore, no indications of trust being influenced by the rise of new ethnic groups or a multiethnic society. All told, ethnic diversity measured in terms of the size of non-western immigrants does not appear to be associated with lower levels of trust in Europe. It may be true in some areas and some countries, but it is not a general phenomenon and problem. Adapted from the source document.

Due to regulatory constraints that prevented the use of outdoor plots for our studies, in 2005 we established multispecies communities in five large cylindrical outdoor sunlit mesocosms (plastic greenhouses) designed for pollen confinement. Three of the community members were sexually compatible Brassica spp.: transgenic glyphosate-resistant canola (B. napus) cultivar (cv.) RaideRR, glyphosate-sensitive non-transgenic B. napus cv. Sponsor, and a weedy B. rapa (GRIN Accession 21735). Additional plant community members were the broadly distributed annual weeds Digitaria sanguinalis, Panicum capillare, and Lapsana communis. Once annually in 2006 and 2007, two mesocosms were sprayed with glyphosate at 10% of the field application rate to simulate glyphosate drift as a selective pressure. After two years, changes were observed in community composition, plant density, and biomass in both control and treatment mesocosms. In control mesocosms, the weed D. sanguinalis (crabgrass) began to dominate. In glyphosate drift-treated mesocosms, Brassica remained the dominant genus and the incidence of the CP4 EPSPS transgene increased in the community. Shoot biomass and mycorrhizal infection in Trifolium incarnatum planted in 2008 were significantly lower in mesocosms that had received glyphosate drift treatments. Our results suggest that, over time, glyphosate drift can contribute to persistence of Brassica that express the CP4 EPSPS transgene and that increased representation of Brassica (a non-mycorrhizal host) within plant communities may indirectly negatively impact beneficial ecosystem services associated with arbuscular mycorrhiza.

II. Using oral slope factor as a measure of carcinogenic potency AN - 867736697; 14522841 AB - The overall risk associated with exposure to a chemical is determined by combining quantitative estimates of exposure to the chemical with their known health effects. For chemicals that cause carcinogenicity, oral slope factors (OSFs) and inhalation unit risks are used to quantitatively estimate the carcinogenic potency or the risk associated with exposure to the chemical by oral or inhalation route, respectively. Frequently, there is a lack of animal or human studies in the literature to determine OSFs. This study aims to circumvent this problem by developing quantitative structure-activity relationship (QSAR) models to predict the OSFs of chemicals. The OSFs of 70 chemicals based on male/female human, rat, and mouse bioassay data were obtained from the United States Environmental Protection Agency's Integrated Risk Information System (IRIS) database. A global QSAR model that considered all 70 chemicals as well as species and/or sex-specific QSARs were developed in this study. Study results indicate that the species and sex-specific QSARs (r 2 >0.8, q 2 >0.7) had a better predictive abilities than the global QSAR developed using data from all species and sexes (r 2 =0.77, q 2 =0.73). The QSARs developed in this study were externally validated, and demonstrated reasonable predictive abilities.

Geographic information system (GIS) maps of environmental information can be useful tools for communities in their assessment of environmental-pollution-related risks. Databases and mapping tools that supply community-level estimates of ambient concentrations of hazardous pollutants, risk, and potential health impacts can provide relevant information for communities to understand, identify, and prioritize potential exposures and risk from multiple sources. An assessment of existing databases and mapping tools was conducted as part of this study to explore the utility of publicly available databases, and three of these databases were selected for use in a community-level GIS mapping application. Queried data from the U.S. EPA's National-Scale Air Toxics Assessment, Air Quality System, and National Emissions Inventory were mapped at the appropriate spatial and temporal resolutions for identifying risks of exposure to air pollutants in two communities. The maps combine monitored and model-simulated pollutant and health risk estimates, along with local survey results, to assist communities with the identification of potential exposure sources and pollution hot spots. Findings from this case study analysis will provide information to advance the development of new tools to assist communities with environmental risk assessments and hazard prioritization.

The development and consolidation of the river basin authorities has not been without difficulties. Experience has shown that the Spanish river basin confederations, the French water agencies and the US valley authorities have been successful. There have also, however, been failures, many attributable to the difficulties of separating the political power of regions and nation-states. In the Ebro River Basin, integrated water resources management was applied even when it crossed the administrative borders of the Autonomous Communities; otherwise, the water produced by the Ebro would be one-quarter of its current volume. Thanks to the integrated management, the Ebro economic region is supplied by major reservoirs, especially the Ebro reservoir. Its major irrigation systems, the Aragon and Catalonia Canal, Bardenas, the Ebro Delta and others, are projects that were conceived under the principle of integrated water management.

Final inter-laboratory validation study AN - 860387920; 14379184 AB - Background, goals, and scope: In response to increasing concerns regarding the potential of chemicals to interact with the endocrine system of humans and wildlife, various national and international programs have been initiated with the aim to develop new guidelines for the screening and testing of these chemicals in vertebrates. Here, we report on the validation of an in vitro assay, the H295R steroidogenesis assay, to detect chemicals with the potential to inhibit or induce the production of the sex steroid hormones testosterone (T) and 17 beta -estradiol (E2) in preparation for the development of an Organization for Economic Cooperation and Development (OECD) test guideline. Methods: A previously optimized and pre-validated protocol was used to assess the potential of 28 chemicals of diverse structures and properties to validate the H295R steroidogenesis assay. These chemicals are comprised of known endocrine-active chemicals and "negative" chemicals that were not expected to have effects on the targeted endpoints, as well as a number of test chemicals with unknown modes of action at the level of the steroidogenic pathway. A total of seven laboratories from seven countries participated in this effort. In addition to effects on hormone production, confounding factors, such as cell viability and possible direct interference of test substances with antibody-based hormone detection assays, were assessed. Prior to and during the conduct of exposure experiments, each laboratory had to demonstrate that they were able to conduct the assay within the margin of predefined performance criteria. Results: With a few exceptions, all laboratories met the key quality performance parameters, and only 2% and 7% of all experiments for T and E2, respectively, were excluded due to exceedance of these parameters. Of the 28 chemicals analyzed, 13 and 14 tested affected production of T and E2, respectively, while 11 and 8 did not result in significant effects on T and E2 production, respectively. Four and six chemicals produced ambiguous results for effects on T and E2 production, respectively. However, four of these cases each for T and E2 were associated with only one laboratory after a personnel change occurred. Significant interference of test chemicals with some of the antibody-based hormone detection systems occurred for four chemicals. Only one of these chemicals, however, significantly affected the ability of the detection system to categorize the chemical as affecting E2 or T production. Discussion and conclusions: With one exception, the H295R steroidogenesis assay protocol successfully identified the majority of chemicals with known and unknown modes of interaction as inducers or inhibitors of T and E2 production. Thus it can be considered a reliable screen for chemicals that can alter the production of sex steroid hormones. One of the remaining limitations associated with the H295R steroidogenesis assay protocol is the relatively small basal production of E2 and its effect on quantifying the decreased production of this hormone with regard to the identification of weak inhibitors. An initial comparison of the data produced in this study with those from in vivo studies from the literature demonstrated the potential of the H295R steroidogenesis assay to identify chemicals affecting hormone homeostasis in whole organisms. Particularly promising was the lack of any false negatives during the validation and the very low number of false positives (1 out of 28 chemicals for each T and E2). Perspectives: Based on the results obtained during this validation study and the accordingly revised test protocols, an OECD draft test guideline was developed and submitted to the OECD working group of the national coordinators of the test guidelines program (WNT) for comments in December 2009.

Methods and Results: A previously reported assay targeting the uidA gene (uidA405) was used as the basis for comparing the taxonomic specificity and sensitivity of qPCR assays targeting the rodA gene (rodA984) and two regions of the multi-copy 23S ribosomal RNA gene (EC23S and EC23S857). Experimental analyses of 28 culture collection strains representing E. coli and 21 related non-target species indicated that the uidA405 and rodA984 assays were both 100% specific for E. coli while the EC23S assay was only 29% specific. The EC23S857 assay was only 95% specific due to detection of E. fergusonii. The uidA405, rodA984, EC23S and EC23S857 assays were 85%, 85%, 100% and 86% sensitive, respectively, in detecting 175 presumptive E. coli culture isolates from fresh, marine and waste water samples. In analyses of DNA extracts from 32 fresh, marine and waste water samples, the rodA984, EC23S and EC23S857 assays detected mean densities of target sequences at ratios of approximately 1:1, 243:1 and 6:1 compared with the mean densities detected by the uidA405 assay. Conclusions: The EC23S assay was less specific for E. coli, whereas the rodA984 and EC23S857 assay taxonomic specificities and sensitivities were similar to those of the uidA405 gene assay. Significance and Impact: The EC23S857 assay has a lower limit of detection for E. coli cells than the uidA405 and rodA984 assays due to its multi-copy gene target and therefore provides greater analytical sensitivity in monitoring for these faecal pollution indicators in environmental waters by qPCR methods.

Catchments in the Upper Mississippi River basin had more land in agricultural uses (51%) than the Missouri or Ohio River basin catchments (25% and 29%, respectively). The difference in agriculture is reflected in the TN concentrations in tributary streams and the great rivers: 5,431 and 2,112 mu g L super(-1) for the Upper Mississippi, 1,751 and 978 mu g L super(-1) for the Missouri, and 1,074 and 1,152 mu g L super(-1) for the Ohio River basins. This agricultural effect was not as evident for tributary stream or great river TP concentrations: 165 and 181 mu g L super(-1) in the Upper Mississippi, 177 and 171 mu g L super(-1) in the Missouri, and 67 and 53 mu g L super(-1) in the Ohio River basins. We set reference thresholds based on the 75th percentile TN and TP concentrations at our least disturbed sites. The TN threshold was exceeded for 50-63% of the tributary stream and 16-55% of great river lengths, with the greatest proportion in the Upper Mississippi River basin. The TP threshold was exceeded in 32-48% of tributary stream and 12-41% of great river lengths. Tributary stream N/P ranged from 67:1 (Ohio) to 210:1 (Upper Mississippi); river N/P ranged from 20:1 (Missouri) to 60:1 (Ohio). N/P indicated that potential N-limitation occurred in 10-21% of total tributary stream length and in 0-46% of great river length; potential P-limitation ranged from 60-83% of cumulative tributary stream length and from 21-98% of cumulative great river length. Total N flux (concentration discharge) was highest in the Upper Mississippi River basin; TP flux was lowest in the Ohio River basin. River TN yields and TP yields for both tributary streams and great rivers, was not significantly different between the sub-basins. Our study empirically links catchment land use and stream chemistry, and demonstrates using monitoring data for estimating nutrient yields at a large regional scale.

AN - 854567493; 20980218 AB - Mechanisms of cardiovascular injuries from exposure to gas and particulate air pollutants are unknown. We sought to determine whether episodic exposure of rats to ozone or diesel exhaust particles (DEP) causes differential cardiovascular impairments that are exacerbated by ozone plus DEP. Male Wistar Kyoto rats (10-12 weeks of age) were exposed to air, ozone (0.4 ppm), DEP (2.1 mg/m(3)), or ozone (0.38 ppm) + DEP (2.2 mg/m(3)) for 5 hr/day, 1 day/week for 16 weeks, or to air, ozone (0.51 or 1.0 ppm), or DEP (1.9 mg/m(3)) for 5 hr/day for 2 days. At the end of each exposure period, we examined pulmonary and cardiovascular biomarkers of injury. In the 16-week study, we observed mild pulmonary pathology in the ozone, DEP, and ozone + DEP exposure groups, a slight decrease in circulating lymphocytes in the ozone and DEP groups, and decreased platelets in the DEP group. After 16 weeks of exposure, mRNA biomarkers of oxidative stress (hemeoxygenase-1), thrombosis (tissue factor, plasminogen activator inhibitor-1, tissue plasminogen activator, and von Willebrand factor), vasoconstriction (endothelin-1, endothelin receptors A and B, endothelial NO synthase) and proteolysis [matrix metalloprotease (MMP)-2, MMP-3, and tissue inhibitor of matrix metalloprotease-2] were increased by DEP and/or ozone in the aorta, but not in the heart. Aortic LOX-1 (lectin-like oxidized low-density lipoprotein receptor-1) mRNA and protein increased after ozone exposure, and LOX-1 protein increased after exposure to ozone + DEP. RAGE (receptor for advanced glycation end products) mRNA increased in the ozone + DEP group. Exposure to ozone or DEP depleted cardiac mitochondrial phospholipid fatty acids (DEP > ozone). The combined effect of ozone and DEP exposure was less pronounced than exposure to either pollutant alone. Exposure to ozone or DEP for 2 days (acute) caused mild changes in the aorta. In animals exposed to ozone or DEP alone for 16 weeks, we observed elevated biomarkers of vascular impairments in the aorta, with the loss of phospholipid fatty acids in myocardial mitochondria. We conclude that there is a possible role of oxidized lipids and protein through LOX-1 and/or RAGE signaling.

AN - 854566168; 20980217 AB - Quantitative high-throughput screening (qHTS) assays are increasingly being used to inform chemical hazard identification. Hundreds of chemicals have been tested in dozens of cell lines across extensive concentration ranges by the National Toxicology Program in collaboration with the National Institutes of Health Chemical Genomics Center. Our goal was to test a hypothesis that dose-response data points of the qHTS assays can serve as biological descriptors of assayed chemicals and, when combined with conventional chemical descriptors, improve the accuracy of quantitative structure-activity relationship (QSAR) models applied to prediction of in vivo toxicity end points. We obtained cell viability qHTS concentration-response data for 1,408 substances assayed in 13 cell lines from PubChem; for a subset of these compounds, rodent acute toxicity half-maximal lethal dose (LD50) data were also available. We used the k nearest neighbor classification and random forest QSAR methods to model LD50 data using chemical descriptors either alone (conventional models) or combined with biological descriptors derived from the concentration-response qHTS data (hybrid models). Critical to our approach was the use of a novel noise-filtering algorithm to treat qHTS data. Both the external classification accuracy and coverage (i.e., fraction of compounds in the external set that fall within the applicability domain) of the hybrid QSAR models were superior to conventional models. Concentration-response qHTS data may serve as informative biological descriptors of molecules that, when combined with conventional chemical descriptors, may considerably improve the accuracy and utility of computational approaches for predicting in vivo animal toxicity end points.

AN - 852902747; 21138393 AB - Systems exposure science has emerged from the traditional environmental exposure assessment framework and incorporates new concepts that link sources of human exposure to internal dose and metabolic processes. Because many human environmental studies are designed for retrospective exposure evaluations they often do not provide practical toxicological outcome parameters. Our goal was to examine concepts from systems biology research and adapt them to a network approach that maps forward to a perturbation event using two hypothetical examples. The article proposes that environmental exposure studies should not only retrospectively document exposure levels, but also measure biological parameters that can be used to inform relevant systemic changes.

Data on household waste management behaviour in Ireland is scarce, and policy making could benefit from improved data and market analysis. In this paper we estimate models of household waste management behaviour in Ireland using econometrics and simple comparison of average effects, but we find that some important parameters cannot be obtained robustly using existing aggregate data. Drawing upon international literature in order to complete our assumptions, we apply a simulation model to illustrate the likely effects of some current policy options. We show that increases in the landfill levy are likely to have little effect on household behaviour if pay-by-use tariffs are not fully implemented, and we find that while introducing additional bins for segregated compostable waste may divert significant quantities of such waste, they are more effective in cities than in rural areas. We also highlight key shortcomings of the available data. Reprinted by permission of Carfax Publishing, Taylor & Francis Ltd.

Previous studies on these species have relied on correlations between frog population status and either a metric for amount of upwind pesticide use or limited measurements of pesticide concentrations in the field. The present study tested the hypothesis that pesticide concentrations are negatively correlated with frog population status (i.e., fraction of suitable water bodies occupied within 2 km of a site) by measuring pesticide concentrations in multiple media twice at 28 sites at high elevation in the southern Sierra Nevada. Media represented were air, sediment, and Pseudacris sierra tadpoles. Total cholinesterase (ChE), which has been used as an indicator for organophosphorus and carbamate pesticide exposure, was also measured in P. sierra tadpoles. Results do not support the pesticide-site occupancy hypothesis. Among 46 pesticide compounds analyzed, nine were detected with =>30% frequency, representing both historically and currently used pesticides. In stepwise regressions with a chemical metric and linear distance from the Central Valley as predictor variables, no negative association was found between frog population status and the concentration of any pesticide or tadpole ChE activity level. By contrast, frog population status showed a strong positive relationship with linear distance from the Valley, a pattern that is consistent with a general west-to-east spread across central California of the amphibian disease chytridiomycosis observed by other researchers.

AN - 851750672; 21237567 AB - Wastewater control at storage terminals of liquid chemical products in bulk is very difficult because of the variety of products handled in the facilities generating effluents of variable composition. The main objective of this work was to verify if the Vibrio fischeri acute toxicity test could be routinely included in the wastewater management of those facilities along with physical and chemical analysis in order to evaluate and improve the quality of the generated effluents. The study was performed in two phases before and after the implementation of better operational practices/treatment technologies. Chemical oxygen demand (COD) and toxicity of treated effluents did not correlate showing that effluents with low COD contain toxic substances and non-biodegradable organic matter, which may be not degraded when discharged into the aquatic environment. Segregation of influents or pre-treatment based on toxicity results and biodegradability index were implemented in the facilities generating significant improvements in the quality of final effluents with reduction of Biochemical oxygen demand (BOD) and toxicity. The integration of physical and chemical analysis with the V. fischeri toxicity test turned out to be an excellent tool for wastewater management in chemical terminals allowing rapid decision making for pollution control and prevention measures. Reuse of rain water was also proposed and when implemented by the facilities resulted in economical and environmental benefits. Copyright © 2010 Elsevier B.V. All rights reserved.

We examined the feasibility of conducting a local assessment of the public health impacts of cumulative air pollution reduction activities from federal, state, local, and voluntary actions in the City of New Haven, Connecticut (USA). Using a hybrid modeling approach that combines regional and local-scale air quality data, we estimated ambient concentrations for multiple air pollutants [e.g., PM2.5 (particulate matter less than or equal to 2.5 mu m in aerodynamic diameter), NOx (nitrogen oxides)] for baseline year 2001 and projected emissions for 2010, 2020, and 2030. We assessed the feasibility of detecting health improvements in relation to reductions in air pollution for 26 different pollutant-health outcome linkages using both sample size and exploratory epidemiological simulations to further inform decision-making needs. Model projections suggested decreases ( similar to 10-60%) in pollutant concentrations, mainly attributable to decreases in pollutants from local sources between 2001 and 2010. Models indicated considerable spatial variability in the concentrations of most pollutants. Sample size analyses supported the feasibility of identifying linkages between reductions in NOx and improvements in all-cause mortality, prevalence of asthma in children and adults, and cardiovascular and respiratory hospitalizations. Substantial reductions in air pollution (e.g., similar to 60% for NOx) are needed to detect health impacts of environmental actions using traditional epidemiological study designs in small communities like New Haven. In contrast, exploratory epidemiological simulations suggest that it may be possible to demonstrate the health impacts of PM reductions by predicting intraurban pollution gradients within New Haven using coupled models.

14432251 AB - Time and size resolved data of trace elements were obtained from measurements with a rotating drum impactor (RDI) and subsequent X-ray fluorescence spectrometry. Trace elements can act as indicators for the identification of sources of particulate matter <10 mu m (PM sub(10)) in ambient air. Receptor modeling was performed with positive matrix factorization (PMF) for trace element data from an urban background site in Zuerich, Switzerland. Eight different sources were identified for the three examined size ranges (PM sub(1-0.1), PM sub(2.5-1) and PM sub(10-2.5)): secondary sulfate, wood combustion, fire works, road traffic, mineral dust, de-icing salt, industrial and local anthropogenic activities. The major component was secondary sulfate for the smallest size range; the road traffic factor was found in all three size ranges. This trace element analysis is complemented with data from an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (AMS), assessing the PM sub(1) fraction of organic aerosols. A separate PMF analysis revealed three factors related to three of the sources found with the RDI: oxygenated organic aerosol (OOA, related to inorganic secondary sulfate), hydrocarbon like organic aerosol (HOA, related to road traffic) and biomass burning organic aerosol (BBOA), explaining 60%, 22% and 17% of total measured organics, respectively. Since different compounds are used for the source classification, a higher percentage of the ambient PM sub(10) mass concentration can be apportioned to sources by the combination of both methods.

Samples, collected during 2001-2009, of springs (n=158), precipitation (n=520), streams (n=176), and firn (n=3) assisted the determinations for meteoric composition of recharge waters. The local mean water line (LMWL) is defined as delta (super 2) H=8.2delta (super 18) O-9.3 for the watershed. Recharge history is surmised from groundwater ages ranging from 5+ or -3 years (apparent (super 85) Kr) to 9,490+ or -420 (super 14) C cal years BP. About 56% of the springs were recharged over the last 1,000 years while 13% of springs were recharged over 5,000 years ago. Spring HDO values fluctuate between -11.8 to -15.6 ppm delta (super 18) O and -90.9 to -119.4 ppm delta (super 2) H. Deuterium excess values predominate around 4-6 ppm. The HDO proxy records from springs suggest a pronounced paleoclimate shift in air masses near 5,000 year BP on the Peninsula.

NILS is conducted as a sample-based stratified inventory that acquires data across several spatial scales, which is accomplished by combining aerial photo interpretation with field inventory. A total of 631 sample units are distributed across the land base of Sweden, of which 20% are surveyed each year. By 2007 NILS completed the first 5-year inventory phase. As the reinventory in the second 5-year phase (2008-2012) proceeds, experiences and insights accumulate and reflections are made on the setup and accomplishment of the monitoring scheme. In this article, the emphasis is placed on background, scope, objectives, design, and experiences of the NILS program. The main objective to collect data for and perform analyses of natural landscape changes, degree of anthropogenic impact, prerequisites for natural biological diversity and ecological processes at landscape scale. Different environmental conditions that can have direct or indirect effects on biological diversity are monitored. The program provides data for national and international policy and offers an infrastructure for other monitoring program and research projects. NILS has attracted significant national and international interest during its relatively short time of existence; the number of stakeholders and cooperation partners steadily increases.

The partitioning of PCBs to the overlying water column was measured with polyethylene samplers and compared to partitioning without resuspension. Greater concentrations of total aqueous (freely dissolved+dissolved organic carbon (DOC)-associated) PCBs were found in all resuspended treatments for PCBs with mid-range K (sub OW) s, but no difference was observed in total aqueous concentrations among different redox conditions. The magnitude of increased concentrations depended on resuspension time and congener K (sub OW) , but ranged from approximately one to eight times those found without resuspension. In a parallel study, DOC was flocculated and removed from smaller-scale NBH sediment resuspensions. In situ K (sub DOC) s were determined and used to calculate freely dissolved and DOC-associated fractions of the increase in total aqueous PCB concentrations due to resuspension. The importance of DOC-associated PCBs increased with increasing K (sub OW) . In situ K (sub DOC) s were approximately one to two orders of magnitude greater than those calculated with a commonly used linear free energy relationship (LFER). The present study demonstrates that resuspension of contaminated sediments releases PCBs to the water column, of which a significant fraction are DOC-associated (e.g., 28, 65, and 90% for PCBs 28, 66, and 110, respectively). Results also imply that site-specific PCB K (sub DOC) s are superior to those calculated with generic LFERs. Environ. Toxicol. Chem. 2011;30:377-384.

Past researchers have developed a conceptual model to explain the 'aging effect' founded in the proposed evolution of copper(II) corrosion by-products on the pipe surface, based on theoretical considerations, anecdotal evidence and some data. In this study, the impact of plumbing age on copper levels in tap water samples and the internal surface corrosion of copper plumbing were systematically evaluated in 16 buildings with plumbing ages ranging from less than one to 44 years, using solids analysis approaches including XPS and XRD. Copper levels decreased with plumbing age and supported theory. A mix of stable and relatively unstable scales appeared on pipes, including cupric hydroxide, cuprite and malachite, although no obvious trend in scale composition with age was noted.

Several studies have suggested that atrazine modifies steroidogenesis and may disrupt reproductive function and development in a variety of species. A primary concern has been whether atrazine increases the synthesis of estrogens, perhaps by enhancing aromatase gene expression and activity. In this study, the effect of atrazine was compared in cultures using primary granulosa cells and H295R adrenal cortical carcinoma cells. Atrazine (10I14M), but not its metabolite, 2-chloro-4,6-diamino-1,2,5-triazine (DACT), significantly increased estradiol production and aromatase activity in granulosa cell cultures only when measured for 1-h following 24h of exposure. In H295R cells, atrazine (10I14M) increased estradiol and estrone production. Importantly, atrazine (10I14M) increased progesterone production from both cell types suggesting a broader effect of atrazine on steroidogenesis.

Hypoxic and anoxic conditions at the sediment-water interface (SWI) are frequently observed in the Gulf of Trieste and in the lagoon, due to strong late summer water stratification and high organic matter input. Mercury mobility at the SWI was investigated at three sampling points located in the Gulf of Trieste (AA1, CZ) and in the Grado Lagoon (BAR). Experiments were conducted under laboratory conditions at in situ temperature, using a dark flux chamber simulating an oxic-anoxic transition. Temporal variations of dissolved Hg and methylmercury (MeHg) as well as O (sub 2) , NH (sub 4) (super +) , NO (sub 3) (super -) +NO (sub 2) (super -) , PO (sub 4) (super 3-) , H (sub 2) S, dissolved Fe and Mn, dissolved inorganic C (DIC) and dissolved organic C (DOC) were monitored simultaneously. Benthic Hg fluxes were higher under anoxic conditions than in the oxic phase of the experiment. Methyl Hg release was less noticeable (low or absent) in the oxic phase, probably due to similar methylation and demethylation rates, but high in the anoxic phase of the experiment. The MeHg flux was linked to SO (sub 4) reduction and dissolution of Fe (and Mn) oxyhydroxides, and formation of sulphides. Re-oxygenation was studied at sampling point CZ, where concentrations of MeHg and Hg dropped rapidly probably due to re-adsorption onto Fe (Mn) oxyhydroxides and enhanced demethylation. Sediments, especially during anoxic events, should be, hence, considered as a primary source of MeHg for the water column in the northern Adriatic coastal areas.

Chitorem SC-20 registered (raw crushed crab shells containing 40% (w/w) CaCO sub(3), 30% protein, 20% chitin, 7% moisture, and 3% ash) and Chitorem SC-80 registered (the chitin polymer containing 88% chitin and 12% moisture) were used to evaluate heavy metals removal from MIW. It was found that SC-20 was very effective at neutralizing the strong acidity of MIW, even at loads as low as 1 g/L the equilibrium pH was neutral. At a load of 2 g/L, SC-20 showed a final pH of 7.94 with almost complete (>99.8%) removal of iron (120 mg/L), lead (1.1 mg/L) and zinc (79 mg/L), along with partial removal of cadmium (96% of 1.3 mg/L), cobalt (54% of 0.78 mg/L), copper (42% of 72 mg/L), and manganese (64% of 52 mg/L) from MIW. Metal removal was achieved primarily by neutralization and precipitation mainly due to the dissolution of the CaCO sub(3) from the SC-20. SC-80 was used to differentiate the effect of alkalinity and the amount of metal adsorption achievable by the chitin polymer. Lead (up to 1.24 mg/g), cadmium (up to 1.81 mg/g), and cobalt (up to 0.93 mg/g) from single-metal solutions were adsorbed onto the chitin polymer (SC-80). Metal adsorption onto the chitin polymer seemed to have a minor role as a mechanism of metal removal from MIW.

The range of CDOM was 0.092m super(-1) at Barataria in June 2008 to 11.225m super(-1) at Mississippi in February 2008. An indicator of organic matter quality was predicted by the spectral slope of absorption coefficients from 350 to 412nm which was between 0.0087m super(-1) at Mississippi in May 2008 and 0.0261m super(-1) at Barataria in June 2008. CDOM was the dominant component of light attenuation at Terrebonne and Barataria. Detritus and CDOM were the primary components of light attenuation at Vermilion, Atchafalaya, and Mississippi. DOC ranged between 65 and 1235 mu M. PIM ranged between 1.1 and 426.3mgL super(-1) and POM was between 0.3 and 49.6mgL super(-1).

Early life exposure to chemicals can result in persistent deficits in nervous system function at later life stages. These effects are often the result of abnormal development of synapses. Given the large number of chemicals in commerce with unknown potential to result in developmental neurotoxicity (DNT), the need exists for assays that can efficiently characterize and quantify chemical effects on brain development including synaptogenesis. The present study describes the application of automated high content image analysis (HCA) technology for examining synapse formation in rodent primary mixed cortical cultures. During the first 15days in vitro (DIV) cortical neurons developed a network of polarized neurites (i.e., axons and dendrites) and expression of the pre-synaptic protein synapsin increased over time. The localization of punctate synapsin protein in close apposition to dendrites also increased, indicating an increase in synapse formation. Results demonstrated that: (1) punctate synapsin protein with a spatial orientation consistent with synaptic contact sites could be selectively measured, (2) the critical period for synaptogenesis in cortical cultures was consistent with previous reports, (3) chemicals known to inhibit synapse formation decreased automated measurements of synapse number and (4) parallel evaluation of neuron density, dendrite length and synapse number could distinguish frank cytotoxicity from specific effects on synapse formation or neuronal morphology. Collectively, these data demonstrate that automated image analysis can be used to efficiently assess synapse formation in primary cultures and that the resultant data is comparable to results obtained using lower throughput methods.

In this study, water samples were collected between September 2004 and October 2008 from five tributaries and were analyzed for 209 polychlorinated biphenyls (PCB) with high-resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS) following EPA Method 1668A. Total PCB concentrations ranged between 0.31 and 42.75ngL super(-1). Congeners between Di and Hexa PCBs accounted between 70 and 99% of the total PCB. The tributary with highest PCB concentrations presented similar pattern and percentage levels to Aroclor 1242. Total average loads for the sampling events ranged between 1.85gd super(-1) and 59.08gd super(-1). PCB concentrations were evaluated against other variables and other studies (including different matrices) to better understand their transport. The methodology used is reliable to assess PCB contamination in surface water.

Our objectives were to evaluate, among chemical rodent control product (rodenticide) users, awareness of non-target effects on wildlife and willingness to change rodent control behaviour given knowledge of possible local non-target effects. Approximately half of respondents to a resident survey in California (USA) practised rodent control; of these, approximately 45% were chemical rodenticide users. Few (10%) were aware of possible non-target effects. Then, we asked subjects about their potential to pursue each of four rodent control behaviours: continue current use, change product use, reduce use, or stop use. Most respondents indicated that they were most likely to change their rodent control behaviour given the knowledge that rodenticides were possibly affecting non-target wildlife. Among the four behaviours, the greatest frequency of respondents indicated a potential change of product(s) used. Concern about rodenticides affecting wildlife was the most consistent predictor of potential to change or not change behaviour. Our results highlight importance of awareness about environmental effects of personal actions, and promotion of stewardship may be most effective if efforts focus on development of long-term personal value in the environment.

The criteria for land use modeling were developed along with a 10-step framework including a comprehensive ecosystem services valuation of scenarios. This research program is defined which includes the development of a user-friendly ecosystem services tool with accompanying default values and recommendations on input parameters which are necessary to develop the scenarios, integration curves, maps, and ecosystem profiles of each scenario. Based on these scenarios, curves, maps, and profiles, additional recommendations may be made on land use practices or regional selections. Finally, a discussion of implementation of the theory behind this methodology focuses on an analysis of biofuels.

Considering the associations between adverse health effects and exposure to ultrafine particles, air quality models may need to accurately simulate particle number size distributions in addition to mass size distributions in future applications. In this study, predictions of particle number and mass size distributions by the Community Multiscale Air Quality model with the standard and an updated emission size distribution are evaluated using wintertime observations in California. Differences in modeled lung deposition fraction for simulated and observed particle number size distributions are also evaluated. Simulated mass size distributions are generally broader and shifted to larger diameters than observations, and observed differences in inorganic and carbon (elemental and organic) distributions are not captured by the model. These model limitations can be reasonably accounted for in regulatory modeling applications. Simulated number size distributions are considerably less accurate than mass size distributions and are difficult to represent in air quality models due to large sub-grid-scale concentration gradients. However, modeled number size distributions are responsive to updates of the emission size distribution, and reasonable simulation of background number size distributions might be possible with an improved treatment of emission size distributions. Modeled lung deposition fractions for simulated number size distributions peak in the same lung region as those for number size distributions observed in the background. However, differences in modeled and observed total number concentrations generally suggest large differences in the total number of deposited particles. Future model development on simulating particle mass size distributions should focus on improving predictions of the mass fraction of particles <2.5 mu m. Model development for particle number size distributions should focus on reducing differences in modeled lung deposition for modeled and observed distributions.

Estimating the degree of dynamic order inherent in the socio-political regime of various countries throughout the world involved applying Fisher information theory to data from the Political Instability Task Force database. Fisher information is a key method in information theory and affords the ability to characterize the structure and dynamics of complex systems. The results of this work demonstrate that nation states bifurcate into two distinct regimes, which exhibit a negative correlation between dynamic order, as determined by Fisher information, and the prevalence of upheavals. Countries in the High Incidence of Upheavals regime with low dynamic order (i.e., low Fisher information) experienced sixteen times more upheavals than the countries in the Low Incidence of Upheavals regime with high dynamic order (i.e. high Fisher information). Most importantly, our analysis demonstrates that newly industrializing countries suffer from the most instability, which is manifested in low dynamic order thereby resulting in a high number of upheavals. These results suggest that developing countries endure a period of socio-political instability on their path to the developed world.

AN - 849010733; 20378750 AB - Recently, investigators demonstrated associations between fine particulate matter (PM)-associated metals and adverse health effects. Residual oil fly ash (ROFA), a waste product of fossil fuel combustion from boilers, is rich in the transition metals Fe, Ni, and V, and when released as a fugitive particle, is an important contributor to ambient fine particulate air pollution. We hypothesized that a single-inhalation exposure to transition metal-rich PM will cause concentration-dependent cardiovascular toxicity in spontaneously hypertensive (SH) rats. Rats implanted with telemeters to monitor heart rate and electrocardiogram were exposed once by nose-only inhalation for 4 hours to 3.5 mg/m(3), 1.0 mg/m(3), or 0.45 mg/m(3) of a synthetic PM (dried salt solution), similar in composition to a well-studied ROFA sample consisting of Fe, Ni, and V. Exposure to the highest concentration of PM decreased T-wave amplitude and area, caused ST depression, reduced heart rate (HR), and increased nonconducted P-wave arrhythmias. These changes were accompanied by increased pulmonary inflammation, lung resistance, and vagal tone, as indicated by changes in markers of HR variability (increased root of the mean of squared differences of adjacent RR intervals [RMSSD], low frequency [LF], high frequency [HF], and decreased LF/HF), and attenuated myocardial micro-RNA (RNA segments that suppress translation by targeting messenger RNA) expression. The low and intermediate concentrations of PM had less effect on the inflammatory, HR variability, and micro-RNA endpoints, but still caused significant reductions in HR. In addition, the intermediate concentration caused ST depression and increased QRS area, whereas the low concentration increased the T-wave parameters. Thus, PM-induced cardiac dysfunction is mediated by multiple mechanisms that may be dependent on PM concentration and myocardial vulnerability (this abstract does not reflect the policy of the United States Environmental Protection Agency).

AN - 843415770; 21195446 AB - Nitrifying biofilters seeded with three different mixed-culture sources removed trichloromethane (TCM) and dibromochloromethane (DBCM) with removals reaching 18% for TCM and 75% for DBCM. In addition, resuspended biofilm removed TCM, bromodichloromethane (BDCM), DBCM, and tribromomethane (TBM) in backwash batch kinetic tests, demonstrating that the biofilters contained organisms capable of biotransforming the four regulated trihalomethanes (THMs) commonly found in treated drinking water. Upon the initial and subsequent increased TCM addition, total ammonia nitrogen (TOTNH(3)) removal decreased and then reestablished, indicating an adjustment by the biofilm bacteria. In addition, changes in DBCM removal indicated a change in activity related to DBCM. The backwash batch kinetic tests provided a useful tool to evaluate the biofilm's bacteria. Based on these experiments, the biofilters contained bacteria with similar THM removal kinetics to those seen in previous batch kinetic experiments. Overall, performance or selection does not seem based specifically on nutrients, source water, or source cultures and most likely results from THM product toxicity, and the use of GAC media appeared to offer benefits over anthracite for biofilter stability and long-term performance, although the reasons for this advantage are not apparent based on research to date.

AN - 840349469; 21072838 AB - Anaerobic biochemical reactors (BCRs) are useful for removing metals from mining-impacted water at remote sites. Removal processes include sorption and precipitation of metal sulfides, carbonates, and hydroxides. A question of interest is whether BCRs remove aquatic toxicity. Influent and effluent samples from the Luttrell Repository and Peerless Jenny King, both in Montana, USA; Park City, Utah, USA; and Standard Mine, Colorado, USA, were examined and compared for removal of metals and aquatic toxicity. Effluent samples from Standard Mine included those having solely BCR treatment and those having BCR treatment followed by aeration in a polishing cell. Metal removal for all sites was >90%. All influent samples were acutely toxic to Ceriodaphnia dubia and Pimephales promelas; toxicity was removed following treatment, except in the Luttrell Repository and Standard Mine BCR samples. Laboratory aeration of undiluted samples eliminated (Standard Mine BCR) or significantly reduced (Luttrell Repository, 65% survival) acute toxicity, most likely through removal of hydrogen sulfide. A toxicity identification evaluation suggested that metals also might be contributing to toxicity in the Luttrell Repository effluent samples; metals other than Mn were either not detected or very low (Fe and Pb) in the Standard Mine BCR samples. Field-aerated samples were not acutely toxic, and only the Luttrell Repository and Standard Mine samples showed short-term subchronic toxicity. Overall, results indicated BCR treatment had high metal removal efficiency and that inclusion of in-field aeration was beneficial in removal of acute and short-term subchronic toxicity. © 2010 SETAC.

In the current study, twelve 24h PM samples were collected (in July-August 2006) using a low-pressure impactor positioned 20m from a Raleigh, North Carolina interstate. The interstate supported a arrow right 4125,000vehicles/d, the majority of which were light-duty gasoline passenger vehicles. The overall near-highway PM mass size distribution was trimodal with a major accumulation mode peak at 500-800nm. PM mass levels reflected daily traffic activity, while mean near-highway PM10 (33A plus or minus 7.5I14gma degree 3), PM2.5 (29A plus or minus 6.8I14gma degree 3), and PM0.1 (1.4A plus or minus 0.3I14gma degree 3) mass levels varied less than 24% over the two week sampling period. The elemental composition of the impactor-collected PM was investigated using magnetic sector inductively coupled plasma-mass spectroscopy (SF-ICPMS). Accumulation mode sulfur (7A plus or minus 4% w/w) was the major inorganic constituent detected at the near-highway site followed by coarse mode group IA and IIA elements likely from re-suspension of crustal matter. As expected, elements regularly detected in asphalt, vehicle, catalyst (e.g., Pt, Rh, and Pd), brake, and tire wear (e.g., Cu and Sb) were also found in the near highway PM. Maximum concentrations of the platinum group, rare earth, and common brake and tire wear elements were observed at d50=1-2I14m, d50=1-4I14m, and d50a[control][yen1-4I14m, respectively. Ten of the eleven metals listed as EPA air toxics (Mn, Cr, Sb, Ni, Pb, As, Co, Cd, Se, and Be) were detected in each PM size fraction but were generally enriched in PM0.1. Several biologically antagonistic suites of metals (Cd, Cu, and V) were found in multiple PM size modes. Some of these metals showed erratic size distributions with daily changes in enrichment (e.g., Ni, Zn, Cd, As, and Cu) and particle size, suggesting a variety of emissions and metal exposure scenarios occurring in the near-highway environment. a-[ordm Daily changes in metal (Ni, Zn, Co, and Cr) size distributions and proportions in particle matter suggest a variety of metal exposure scenarios are possible in the near-highway environment. a-[ordm Hazardous metal air pollutants in the near-highway atmosphere tend to concentrate in ultrafine particles. a-[ordm Pb and As levels are well correlated, unimodally distributed, and show traffic-influenced concentration changes in the near-highway environment.

Both networks use modeled dry deposition velocities and measured atmospheric concentrations to compute estimates of dry deposition. While concentration measurements from the two networks are comparable, flux estimates can be significantly different due to differences in the model-estimated dry deposition velocities. This study intercompares the dry deposition velocity models used by the networks to identify those model inputs and model algorithms that are responsible for the differences in the dry deposition velocity predictions of the gaseous trace species ozone (O3), sulfur dioxide (SO2), and nitric acid (HNO3). The Big-Leaf Model (BLM) used for CAPMoN was inserted into the CASTNET modeling framework so that the on-site meteorological data obtained at the CASTNET sites could be used as input to both models. The models were run for four CASTNET sites that spanned different land use types and climatologies. The models were incrementally modified to assess the impacts of algorithmic differences on the predicted deposition velocities. While differences in aerodynamic resistance between the models contributed strongly to differences in predicted dry deposition velocities for HNO3, it is the non-stomatal (ground and cuticle) resistance parameterizations that cause the largest differences for other chemical species. The study points to the need for further consideration of these resistances. Additionally, comparisons of both models against recent independent flux data are needed to assess the accuracy of the models.

This included classical measures of endocrine exposure such as impacts on testosterone (T), 17 beta -estradiol (E2), and vitellogenin (VTG) concentrations in plasma, as well as determination of effects on the hepatic metabolome using proton nuclear magnetic resonance spectroscopy. In addition, the rates of production of T and E2 in ovary explants were measured, as were changes in a number of ovarian gene transcripts hypothesized to be relevant to androgen exposure. A temporally intensive 16-d test design was used to assess responses both during and after the TRB exposure (i.e., depuration/recovery). This strategy revealed time-dependent responses in females (little impact was seen in the males), in which changes in T and E2 production in the ovary, as well as levels in plasma, declined rapidly (within 1 d), followed shortly by a return to control levels. Gene expression measurements revealed dynamic control of transcript levels in the ovary and suggested potential mechanisms for compensation during the exposure phase of the test. Proton nuclear magnetic resonance spectroscopy revealed a number of hepatic metabolite changes that exhibited strong time and dose dependence. Furthermore, TRB appeared to induce the hepatic metabolome of females to become more like that of males at both high test concentrations of TRB (472 ng/L) and more environmentally relevant levels (33 ng/L).

Results of the T47D-KBluc assay were compared with the induction of estrogen receptor-regulated gene transcription in male fathead minnows (Pimephales promelas) exposed to the same effluents. Effluent samples for the paired studies were collected over the course of three months. According to the T47D-KBluc assay, the effluent estrogenicity ranged from 1.13 to 2.00 ng 17 beta -estradiol (E2) equivalents/L. Corresponding in vivo studies exposing male fathead minnows to 0, 10, 50, and 100% effluent dilutions demonstrated that exposure to 100% effluent significantly increased hepatic vitellogenin (VTG) and estrogen receptor subunit transcripts relative to controls. The induction was also significant in males exposed to 250 ng E2/L or 100 ng E2/L. The in vitro and in vivo results support the conclusion that the effluent contains significant estrogenic activity, but there was a discrepancy between in vitro- and in vivo-based E2 equivalent estimates. Our results suggest that the direct effluent preparation method for the T47D-KBluc assay is a reasonable approach to estimate the estrogenicity of wastewater effluent.

AN - 1777118917; 14430335 AB - Although laboratory toxicology tests are generally easy to perform, cost effective, and readily interpreted, they have been questioned for their environmental relevance. In contrast, field tests are considered realistic while producing results that are difficult to interpret and expensive to obtain. Toxicology tests were conducted on potatoes, peas, and soybeans grown in a native soil in pots in the greenhouse and were compared to plants grown outside under natural environmental conditions to determine toxicological differences between environments, whether different plant developmental stages were more sensitive to herbicides, and whether these species were good candidates for plant reproductive tests. The reproductive and vegetative endpoints of the greenhouse plants and field-grown plants were also compared. The herbicides bromoxynil, glyphosate, MCPA ([4-chloro-2-methylphenoxy] acetic acid), and sulfometuron-methyl were applied at below field application rates to potato plants at two developmental stages. Peas and soybeans were exposed to sulfometuron-methyl at similar rates at three developmental stages. The effective herbicide concentrations producing a 25% reduction in a given measure differed between experimental conditions but were generally within a single order of magnitude within a species, even though there were differences in plant morphology. This study demonstrated that potatoes, peas, and soybeans grown in pots in a greenhouse produce phytotoxicity results similar to those grown outside in pots; that reproductive endpoints in many cases were more sensitive than vegetative ones; and that potato and pea plants are reasonable candidates for asexual and sexual reproductive phytotoxicity tests, respectively. Plants grown in pots in a greenhouse and outside varied little in toxicity. However, extrapolating those toxicity results to native plant communities in the field is basically unknown and in need of research.

Research on the effects of anti-androgens in fish has been characterized by a heavy reliance on apical endpoints, and molecular mechanisms of action (MOA) of anti-androgens remain poorly elucidated. In the present study, we examined effects of a short term exposure (24-96h) to the androgen receptor antagonists flutamide (FLU) and vinclozolin (VZ) on gene expression in gonads of sexually mature zebrafish, using commercially available zebrafish oligonucleotide microarrays (4-44K platform). We found that VZ and FLU potentially impact reproductive processes via multiple pathways related to steroidogenesis, spermatogenesis, and fertilization. Observed changes in gene expression often were shared by VZ and FLU, as demonstrated by overlap in differentially-expressed genes and enrichment of several common key pathways including: (1) integrin and actin signaling, (2) nuclear receptor 5' signaling, (3) fibroblast growth factor receptor signaling, (4) polyamine synthesis, and (5) androgen synthesis. This information should prove useful to elucidating specific mechanisms of reproductive effects of anti-androgens in fish, as well as developing biomarkers for this important class of endocrine-active chemicals.

The new model system runs as a single executable with 2-way data communication between the WRF and CMAQ components via IOAPI_3 buffer files. This design requires minimal changes to either model which allows for easy updating and maintenance of compatibility with the "off-line" system. The main purposes of the coupled model are: 1) to allow efficient frequent data exchange for high resolution (down to 1 km grid cell size) simulations, 2) to allow feedback of gases and aerosols from CMAQ to WRF where they can affect radiation and microphysics processes, 3) to allow for more integrated treatment of chemical and physical processes. The direct effects of aerosols on shortwave radiation and the direct effects of tropospheric ozone on longwave (LW) radiation have been implemented in the CAM and RRTMG radiation schemes. A new Mie scattering algorithm has been developed for a wider range of wavelengths including LW. New mixing state treatments for aerosols containing black carbon and other constituents such as sulfate and organic carbon have been developed and tested. New model simulations of the 2-way WRF-CMAQ using the latest versions of both models have been evaluated for a summer month in the eastern US and an outbreak of wild fires in California in 2008. Comparisons between runs with and without direct feedbacks show significant impacts on solar radiation, 2-m temperature, PBL height, and ozone and PM2.5 concentrations, especially in areas affected by smoke plumes. The 2-way WRF-CMAQ also includes an experimental implementation of indirect effects where aerosols from CMAQ are activated as cloud condensation nuclei which determine the droplet number concentration for the cloud microphysics model. The resulting effective droplet radius is used in the radiation model to compute cloud optical properties. The indirect effects are being tested by evaluation of cloud radiative forcing compared to satellite measurements. JF - American Meteorological Society. [np]. 23 Jan 2011.

The bias is relative to the dissimilarity between the analyte and internal standard physical properties that influence how easily analytes are separated from a matrix and concentrated during analysis. Method 5032 is a vacuum distillation procedure for extracting analytes from a sample for use with Method 8260C. Vacuum distillation is also incorporated within another GC/MS analytical procedure, Method 8261A. Method 8260C/5032 and Method 8261A are experimentally identical, however, Method 8261A uses internal standards differently by relating the recovery of each compound to its boiling point and relative volatility. By processing each analysis (water, soil, and biota) using both Method 8260C and Method 8261A, the two approaches are compared on the basis of analyte bias and the failure rate of the quality controls. Analytes were grouped by how similar their boiling points and natural log of their relative volatilities (ln RVs) were to their Method 8260C recommended ISTDs. For the most similar analytes, the Method 8260C determinations yielded an average bias less than 10% and a failure to meet calibration criteria less than 7%. However, as the difference between analyte and ISTD became greater the bias increased to over 40% (matrix dependent) and its calibration failure rate approached 70%. In comparison, when the Method 8260C data were reprocessed as Method 8261A determinations, this trend for groupings was minimized with biases increasing from 6% to only 20% and the calibration failure rate went from 0% to 15%.

Unfortunately, NP are beyond the diffraction limit of resolution for conventional light microscopy (~200 nm). Fluorescence and electron microscopy techniques commonly used to examine NP interactions with biological substrates have drawbacks that limit their usefulness in toxicological investigation of NP. EM is labor intensive and slow, while fluorescence carries the risk of photobleaching the sample and has size resolution limits. In addition, many relevant particles lack intrinsic fluorescence and therefore can not be detected in this manner. To surmount these limitations, we evaluated the potential of a novel combination of darkfield and confocal laser scanning microscopy (DF-CLSM) for the efficient 3D detection of NP in human lung cells. The DF-CLSM approach utilizes the contrast enhancements of darkfield microscopy to detect objects below the diffraction limit of 200 nm based on their light scattering properties and interfaces it with the power of confocal microscopy to resolve objects in the z-plane. Validation of the DF-CLSM method using fluorescent polystyrene beads demonstrated spatial colocalization of particle fluorescence (Confocal) and scattered transmitted light (Darkfield) along the X, Y, and Z axes. DF-CLSM imaging was able to detect and provide reasonable spatial locations of 27 nm TiO2 particles in relation to the stained nuclei of exposed BEAS 2B cells. Statistical analysis of particle proximity to cellular nuclei determined a significant difference between 5 min and 2 hr particle exposures suggesting a time-dependant internalization process. DF-CLSM microscopy is an alternative to current conventional light and electron microscopy methods that does not rely on particle fluorescence or contrast in electron density. DF-CLSM is especially well suited to the task of establishing the spatial localization of nanoparticles within cells, a critical topic in nanotoxicology. This technique has advantages to 2D darkfield microscopy as it visualizes nanoparticles in 3D using confocal microscopy. Use of this technique should aid toxicological studies related to observation of NP interactions with biological endpoints at cellular and subcellular levels.

Use of coarse-scale taxonomy can obscure signal about biological condition, particularly if the range of species tolerances is large within genera or families. We hypothesized that integration of deoxyribonucleic acid (DNA) barcodes (partial cytochrome c oxidase subunit I sequences) into bioassessment protocols would provide greater discriminatory ability than genus-level identifications and that this increased specificity could lead to more sensitive assessments of water quality and habitat. Analysis of DNA barcodes from larval specimens of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa collected as part of Maryland's Biological Stream Survey (MBSS) revealed similar to 2 to 3 as many DNA-barcode groups or molecular operational taxonomic units (mOTUs) as morphologically identified genera. As expected, geographic distributions for several mOTUs were tighter than for the parent genus, but few mOTUs showed closer associations with water-quality variables or physical-habitat features than did the genus in which they belonged. The need for improved protocols for the consistent generation of DNA barcodes is discussed.

AN - 821194510; 20974496 AB - Pesticides are nearly ubiquitous in surface waters of the United States, where they often are found as mixtures. The molecular mechanisms underlying the toxic effects of sub-lethal exposure to pesticides as both individual and mixtures are unclear. The current work aims to identify and compare differentially expressed proteins in brains of male fathead minnows (Pimephales promelas) exposed for 72 h to permethrin (7.5 μg/L), terbufos (57.5 μg/L) and a binary mixture of both. Twenty-four proteins were found to be differentially expressed among all three treatments relative to the control using an ANOVA followed by a Dunnett's post hoc test (p ≤0.05). One protein was found to be differentially expressed among all treatment groups and one protein was in common between the terbufos and the mixture group. Fifteen spots were successfully sequenced using LC-MS/MS sequencing. Proteins associated with the ubiquitin-proteasome system, glycolysis, the cytoskeleton and hypoxia were enriched. As a second objective, we attempted to establish protein expression signatures (PES) for individual permethrin and terbufos exposures. We were unable to generate a useable PES for terbufos; however, the permethrin PES was able to distinguish between control and permethrin-exposed individuals in an independent experiment with an accuracy of 87.5%. This PES also accurately classified permethrin exposed individuals when the exposure occurred as part of a mixture. The identification of proteins differentially expressed as a result of pesticide exposure represent a step forward in the understanding of mechanisms of toxicity of permethrin and terbufos. They also allow a comparison of molecular responses of the binary mixture to single exposures. The permethrin PES is the first step in establishing a method to determine exposures in real-world scenarios. Published by Elsevier B.V.

AN - 848688140; 21142172 AB - Zinc oxide nanoparticles (ZnO NPs) are being rapidly developed for use in consumer products, wastewater treatment, and chemotherapy providing several possible routes for ZnO NP exposure to humans and aquatic organisms. Recent studies have shown that ZnO NPs undergo rapid dissolution to Zn(2+), but the relative contribution of Zn(2+) to ZnO NP bioavailability and toxicity is not clear. We show that a fraction of the ZnO NPs in suspension dissolves, and this fraction cannot account for the toxicity of the ZnO NP suspensions to Daphnia magna. Gene expression profiling of D. magna exposed to ZnO NPs or ZnSO(4) at sublethal concentrations revealed distinct modes of toxicity. There was also little overlap in gene expression between ZnO NPs and SiO(x) NPs, suggesting specificity for the ZnO NP expression profile. ZnO NPs effected expression of genes involved in cytoskeletal transport, cellular respiration, and reproduction. A specific pattern of differential expression of three biomarker genes including a multicystatin, ferritin, and C1q containing gene were confirmed for ZnO NP exposure and provide a suite of biomarkers for identifying environmental exposure to ZnO NPs and differentiating between NP and ionic exposure.

The NO sub(x) bias has been shown in model evaluations using aircraft data (Singh et al., 2007) and total column NO sub(2) (molecules cm super(-2)) from satellite observations (Napelenok et al., 2008). The causes of NO sub(x) underpredictions have yet to be fully understood due to the interconnected nature of simulated emission, transport, and chemistry processes. Recent observation-based studies, in the upper troposphere, identify chemical rate coefficients as a potential source of error (Olson et al., 2006; Ren et al., 2008). Since typical chemistry evaluation techniques are not available for upper tropospheric conditions, this study develops an evaluation platform from in situ observations, stochastic convection, and deterministic chemistry. We derive a stochastic convection model and optimize it using two simulated datasets of time since convection, one based on meteorology, and the other on chemistry. The chemistry surrogate for time since convection is calculated using seven different chemical mechanisms, all of which predict shorter time since convection than our meteorological analysis. We evaluate chemical simulations by inter-comparison and by pairing results with observations based on NO sub(x):HNO sub(3), a photochemical aging indicator. Inter-comparison reveals individual chemical mechanism biases and recommended updates. Evaluation against observations shows that all chemical mechanisms overpredict NO sub(x) removal relative to long-lived methanol and carbon monoxide. All chemical mechanisms underpredict observed NO sub(x) by at least 30%, and further evaluation is necessary to refine simulation sensitivities to initial conditions and chemical rate uncertainties.

A growing body of evidence suggests that MeHg exposure can also lead to increased risks of adverse cardiovascular impacts in exposed populations. The U.S. EPA assembled the authors of this article to participate in a workshop, where we reviewed the current science concerning cardiovascular health effects of MeHg exposure via fish and seafood consumption and provided recommendations concerning whether cardiovascular health effects should be included in future Hg regulatory impact analyses. We found the body of evidence exploring the link between MeHg and acute myocardial infarction (MI) to be sufficiently strong to support its inclusion in future benefits analyses, based both on direct epidemiological evidence of an MeHg-MI link and on MeHg's association with intermediary impacts that contribute to MI risk. Although additional research in this area would be beneficial to further clarify key characteristics of this relationship and the biological mechanisms that underlie it, we consider the current epidemiological literature sufficiently robust to support the development of a dose-response function. We recommend the development of a dose-response function relating MeHg exposures with MIs for use in regulatory benefits analyses of future rules targeting Hg air emissions.

Additionally, voluntary best practices firms adopt to achieve environmental performance that exceed regulatory requirements are largely limited to reduced impact logging (RIL) systems that reduce harvest damage relative to conventional logging systems used by a large majority of firms in the region. Existing regulations combined with best practices may not be adequate to ensure sustained yields. This inadequacy is an important issue as Brazil implements an ambitious program of forest concessions on public lands. We analyze the profitability and environmental outcomes of best logging practices and proposed sustainability requirements. We propose two operational definitions of sustainability (the first focusing on sustaining stand-level timber volumes and the other focusing on sustaining species-level volumes within the stand) based on sustaining timber inventories across cutting cycles rather than on sustaining overall harvest yields. RIL is shown to be profitable for loggers and increase the timber available for future harvests. While volume predicted to be available for the second and third harvests are significantly lower than the available timber in the unlogged forest, the second and third harvests are projected to be profitable and have the potential for sustainability despite high opportunity costs. However, as harvesting is repeated into the future, results show the composition of the harvest shifts from higher-value shade-tolerant and emergent species toward a greater reliance on longer-lived, lower-value pioneer species.

Presently, information is insufficient to estimate risks posed to human health and the environment from the over ten thousand chemical substances currently in use and the hundreds more that are introduced each year. The vast majority of chemicals in products with wide commercial use are not measured in the environment, and potential for human exposure is not quantified. Regulatory agencies in North America and Europe have increased calls to address exposure to these chemicals. New, more reliable approaches are needed to characterize thousands of environmental chemicals on the basis of both hazard and exposure in a rapid and efficient manner, and to prioritize chemicals based on potential risk. Various approaches for prioritization based on exposure potential are summarized and compared. Knowledge gaps and research needed to facilitate rapid exposure-based prioritization for chemical evaluation are highlighted.

In order to characterize groundwater hydrochemistry in the area, an investigation has been conducted on 35 wells that were monitored since 2006. Leaching tests were performed (under anaerobic conditions with deionized and saline waters) on two core samples in the area to study the iron release from soils to groundwater. Collected data indicated the main role of salinity in metal leaching and highlighted spatial correspondence between high levels of chloride and iron. To understand the mechanism of groundwater salinization, sulphate/chloride ratio has been investigated and a statistical relation between salinity, pH and iron was found. These data do not show any relation between past activities and high iron groundwater contents. High iron concentrations are diffuse in the whole area and therefore comparable to background values. Consequently, the study states that no remediation plan should have been made for iron concentrations in this area.

Days when pollution is transported into the Northeastern United States (U.S.) were identified by using back-trajectories from the eight regions. These back-trajectories help identify predominant meteorological patterns associated with "polluted" air parcels (originating in the Midwest where power plant emissions are known to be relatively high) and "clean" air parcels (originating from the North where pollution is known to be relatively low). Ambient ozone concentrations measurements were used to validate the classification of "polluted" and "clean" air parcels. These classifications were then used to define the days of high-versus low-exposure for populations residing within each region. The results of this analysis indicate that the risk of being hospitalized for respiratory-related illness in NYS is greater on those days when air is transported from the Midwest as compared to days when air is transported from the North. Using a refined method to examine air parcels moving through a boundary drawn around high-emitting power plants in the Midwestern U.S. resulted in stronger associations across more regions (significant odds ratios ranging from 1.06 to 1.16 for the entire study time period for six of the eight NYS regions). An assessment of temperature and its impact on the odds ratio calculation in the New York City metropolitan region indicates that temperature alone does not explain the increased association between air pollution and respiratory-related hospital admissions.

Initially, we allocated samples using a spatially balanced random design. We then resampled the harbor, but allocated samples to a few targeted areas. We detected 21 non-native invertebrate and 10 non-native fish species; however, many rare zooplankton and benthic invertebrates were likely missed. The two designs did not have significantly different species accumulation curves, but the targeted area design samples had higher species richness and detected non-native species with a significantly higher probability. It was possible to reduce the effort required to detect established non-native species. In contrast, the effort required to detect an ultra-rare, newly arrived species remained large. Based on statistical estimation theory, the effort required to detect 95% or more of species present could exceed enumerating 750 zooplankton samples ( similar to 500 000 individuals, similar to 90 species), 150 benthic invertebrate samples ( similar to 100 000 individuals, similar to 250 species), and 100 fish samples ( similar to 75 000 individuals, similar to 40 species).Original Abstract: En menant une etude de cas dans le port de Duluth-Superieur - un port des Grands Lacs qui subit une pression intense d'introduction d'especes non indigenes - notre objectif est de determiner les efforts requis pour obtenir une forte probabilite de detection du zooplancton, des invertebres benthiques et des poissons non indigenes. Au depart, nous avons reparti les prelevements selon un plan d'echantillonnage aleatoire spatialement equilibre. Nous avons ensuite echantillonne de nouveau le port, mais fait les prelevements dans un nombre limite de zones strategiques. Nous avons detecte 21 especes d'invertebres et 10 especes de poissons non indigenes; cependant, nous avons vraisemblablement manque plusieurs especes de zooplancton et d'invertebres benthiques rares. Les deux plans produisent des courbes d'accumulation d'especes qui ne sont pas significativement differentes, mais le plan qui cible certaines zones particulieres donne des richesses specifiques plus elevees et detecte les especes non indigenes avec une probabilite significativement plus grande. En revanche, l'effort necessaire pour detecter les especes ultrarares et nouvellement arrivees reste eleve. D'apres la theorie de l'estimation statistique, l'effort requis pour detecter 95 % ou plus des especes presentes pourrait depasser une enumeration de 750 echantillons de zooplancton (~500 000 individus, ~90 especes), 150 echantillons d'invertebres benthiques (~100 000 individus, ~250 especes) et 100 echantillons de poissons (~75 000 individus, ~40 especes).

This article also discusses three possible rationales for including works of literary criticism in a library's core undergraduate collection. The first rationale posits a work in the collection that is commonly used in the classroom or helps inform the assumptions and methods encountered there. The second rationale is that a work deserves to be included in an undergraduate collection because it is an extremely important predecessor to the kinds of works covered by the first rationale. The final rationale for including a work of literary criticism is that it is not important to current critical discourse. Adapted from the source document.

Heterogeneity in the hydraulic conductivity field is represented by a collection of streamtubes with a distribution of travel times, and the DNAPL is assumed to be distributed uniformly across all streamtubes. Dissolution from each streamtube is assumed to follow Raoult's law. Results are used to assess how multi-component dissolution alters the source function relative to single component dissolution, as well as assess the relative importance of hydraulic conductivity heterogeneity and multi-component dissolution on the source function. Source functions for both single and multi-component DNAPLs indicate that flushing efficiency decreases as solubility decreases. However, this effect is more pronounced for the less soluble compounds in the multi-component case due to the preferential elution of the more soluble compounds. Source functions for both single and multi-component DNAPLs also indicate that greater flux reduction is achieved through less mass removal as heterogeneity increases, however the effect is less pronounced in the multi-component case.

However, the question arises as to whether these shifts are apparent in all environmental policy sub-domains. And which explanations are to be given for observed differences in specific sub-domains? In this article we introduce insights from policy science literature on drivers of and barriers to shifts towards governance, providing an analytical framework to illustrate and explain the changes in environmental policy in general, and in noise policy specifically. Dutch environmental policy in general has changed distinctly from previous decades: from high profile execution by public institutions and the use of coercive policy instruments into an increasing reliance on dialogue, networks and social inclusion. Dutch noise policy, however, is still state dominated and its legislative approach seems to better fit the dominant style of government. In this paper, we show that while shifts in governance and a changing role of the state are evident for environmental policy, as a whole, similar shifts are not seen in noise policy. The main barriers to such a shift are actors with a vested interest in maintaining the current policy arrangements and the institutional settings which are not considered problematic in achieving national and municipal goals. In addition, drivers for change such as severe incidents which have resulted in shifts in environmental governance, were largely absent from the noise policy domain. Adapted from the source document.

The northern breeding range of Common Loon has contracted over the last century as a result of habitat degradation from human disturbance and lakeshore development. We focused on the state of New Hampshire, USA, where a long-term monitoring program conducted by the Loon Preservation Committee has been collecting biological data on Common Loon since 1976. The Common Loon population in New Hampshire is distributed throughout the state across a wide range of lake-specific habitats, water quality conditions, and levels of human disturbance. We used a multiscale approach to evaluate the association of Common Loon and breeding habitat within three natural physiographic ecoregions of New Hampshire. These multiple scales reflect Common Loon-specific extents such as territories, home ranges, and lake-landscape influences. We developed ecoregional multiscale models and compared them to single-scale models to evaluate model performance in distinguishing Common Loon breeding habitat. Based on information-theoretic criteria, there is empirical support for both multiscale and single-scale models across all three ecoregions, warranting a model-averaging approach. Our results suggest that the Common Loon responds to both ecological and anthropogenic factors at multiple scales when selecting breeding sites. These multiscale models can be used to identify and prioritize the conservation of preferred nesting habitat for Common Loon populations.Original Abstract: Le Plongeon huard (Gavia immer) est considere comme un representant emblematique et ecologiquement important de la faune dependante du milieu aquatique en Amerique du Nord. L'aire de reproduction du Plongeon huard a subi une contraction depuis le siecle passe en raison de la degradation de son habitat consecutive au derangement humain et a l'augmentation de l'occupation humaine sur les bords de lacs. Nous avons choisi le cas du New Hampshire, E.-U., car il y existe un programme de suivi a long terme effectue par le Loon Preservation Committee, qui collige les donnees biologiques sur l'espece depuis 1976. La population du Plongeon huard est repartie partout dans cet Etat, selon une grande variete de milieux lacustres, de conditions de qualite d'eau et de degres de derangement humain. Nous avons utilise une approche multi-echelles afin d'evaluer la relation entre le Plongeon huard et son habitat de nidification, dans trois ecoregions physiographiques naturelles au New Hampshire. Ces differentes echelles refletent d'autres caracteristiques relatives au Plongeon huard, comme les territoires, les domaines vitaux et les influences lac-paysage. Nous avons elabore des modeles multi-echelles ecoregionaux et les avons compares a des modeles tenant compte d'une seule echelle pour evaluer leur performance a distinguer correctement l'habitat de nidification du Plongeon huard. D'apres les criteres de la theorie de l'information, les observations empiriques soutiennent les modeles multi-echelles tout comme les modeles a une seule echelle, dans les trois ecoregions, resultat qui justifie une approche fondee sur la moyenne des modeles. Nos resultats laissent croire qu'au moment de selectionner son site de nidification, le Plongeon huard reagit tout autant aux facteurs ecologiques qu'aux facteurs anthropiques, a differentes echelles. Il est possible d'utiliser ces modeles multi-echelles pour determiner l'habitat de nidification de predilection des populations de Plongeon huard et pour en prioriser la conservation.

We have conducted analyses focusing on studies with rigorous exposure definitions to provide quantitative evaluations of the evidence for associations between TCE and these specific cancers. METHODS: A systematic review of over 70 studies on TCE and cancer documented essential design features, exposure assessment approaches, statistical analyses, and potential sources of confounding and bias. Twenty-four cohort and case-control studies with high exposure potential were identified. Fixed and random effects models were fitted to the data on overall exposure and on the highest exposure group. Sensitivity analyses examined the influence of alternative risk estimate selections. RESULTS: For overall TCE exposure and kidney cancer, the summary risk estimate (RRm) from the fixed effect model was 1.27 (95% CI 1.13 to 1.43) with a higher RRm for the highest exposure groups (1.58, 95% CI 1.28 to 1.96). The RRm were not overly sensitive to alternative selections or to removal of an individual study. There was no apparent heterogeneity or publication bias. Less evidence was found for liver cancer and NHL. CONCLUSIONS: Our findings support an association between TCE exposure and kidney cancer.

Conventional DNT neuropathology endpoints are qualitative histopathology and morphometric endpoints of particularly vulnerable sites (e.g., cerebral, cerebellar, or hippocampal thickness). Novel imaging and stereology measurements hold promise for automated analysis of factors that cannot be effectively examined in routinely processed specimens (e.g., cell numbers, fiber tract integrity). The panel recommended that dedicated DNT neuropathology data sets be acquired on a minimum of 8 sections (for qualitative assessment) or 3 sections (for quantitative linear and stereological analyses) using a small battery of stains to examine neurons and myelin. Where guidelines permit discretion, immersion fixation is acceptable for younger animals (postnatal day 22 or earlier), and peripheral nerves may be embedded in paraffin. Frequent concerns regarding DNT data sets include false-negative outcomes due to processing difficulties (e.g., lack of concordance among sections from different animals) and insensitive analytical endpoints (e.g., qualitative evaluation) as well as false-positive results arising from overinterpretation or misreading by inexperienced pathologists.

While neuropathological assessments provide insight as to cellular changes in neurons, behavioral and physiological methods evaluate the functional consequences of disruption of neuronal communications. The underlying causes of certain behavioral alterations may be understood, but many do not have known direct associations with specific brain pathologies. In some cases, however, rapidly expanding mouse models (transgenic, knock-out) are providing considerable information on behavioral phenotypes of altered pathology. Behavior represents the integrated sum of activities mediated by the nervous system, and functional tests used for neurotoxicity testing tap different behavioral repertoires. These tests have an advantage over pathologic measures in that they permit repeated evaluation of a single animal over time to determine the onset, progression, duration, and reversibility of a neurotoxic injury. Functional assays range from a screening-level battery of tests to refined procedures to tap specific forms of learning and/or memory. This article reviews common procedures for behavioral toxicity testing and provides examples of chemical-specific neurobehavioral-pathological correlations in order to inform interpretation and integration of neuropathological and behavioral outcomes.

Zinc species identified in preamendment sediment were zinc hydroxide-like phases, sphalerite, and zinc sorbed to an iron oxide via X-ray adsorption near edge structure (XANES) spectroscopy. Four months after adding the amendments to the contaminated sediment, hopeite, a Zn phosphate mineral, was identified indicating phosphate was binding and sequestering available Zn and Zn pore water concentrations were decreased at levels of 90% or more. Laboratory experiments indicate organic amendments exhibit a limited effect and may hinder sequestration or pore water Zn when mixed with apatite. The acute toxicity of the sediment Zn was evaluated with Hyalella azteca, and bioaccumulation of Zn with Lumbriculus variegates. The survivability of H. azteca increased as a function of phosphate (apatite) loading rate. In contaminated sediment without apatite, no specimens of H. azteca survived. The bioaccumulation of Zn in L. variegates also followed a trend of decreased bioaccumulation with increased phosphate loading in the contaminated sediment. The research supports an association between Zn speciation and bioavailability.

Conventional techniques to optimally prepare and evaluate the central and peripheral neural tissues while minimizing artifact were reviewed, and optimal schemes were set forth for evaluation of the nervous system during both routine (i.e., general toxicity) studies and enhanced (i.e., specialized neurotoxicity) studies. Stereology was introduced as the most appropriate means of examining the possible impact of toxicants on neural cell numbers. A focused discussion on brain sampling took place among a panel of expert neuroscientists (anatomists and pathologists) and the audience regarding the proper balance between sufficient sampling and cost- and time-effectiveness of the analysis. No consensus was reached on section orientation (coronal sections of both sides vs. a parasagittal longitudinal section with several unilateral hemisections from the contralateral side), but most panelists favored sampling at least 8 sections (or approximately double to triple the current complement) in routine toxicity studies.

OBJECTIVES: To determine the differential effects on blood pressure and vascular function of daily changes in community ambient- versus personal-level PM2.5 measurements. METHODS: Cardiovascular outcomes included vascular tone and function and blood pressure measured in 65 non-smoking subjects. PM2.5 exposure metrics included 24 h integrated personal- (by vest monitors) and community-based ambient levels measured for up to 5 consecutive days (357 observations). Associations between community- and personal-level PM2.5 exposures with alterations in cardiovascular outcomes were assessed by linear mixed models. RESULTS: Mean daily personal and community measures of PM2.5 were 21.9 plus or minus 24.8 and 15.4 plus or minus 7.5 mu g/m3, respectively. Community PM2.5 levels were not associated with cardiovascular outcomes. However, a 10 mu g/m3 increase in total personal-level PM2.5 exposure (TPE) was associated with systolic blood pressure elevation (+1.41 mm Hg; lag day 1, p<0.001) and trends towards vasoconstriction in subsets of individuals (0.08 mm; lag day 2 among subjects with low secondhand smoke exposure, p=0.07). TPE and secondhand smoke were associated with elevated systolic blood pressure on lag day 1. Flow-mediated dilatation was not associated with any exposure. CONCLUSIONS: Exposure to higher personal-level PM2.5 during routine daily activity measured with low-bias and minimally-confounded personal monitors was associated with modest increases in systolic blood pressure and trends towards arterial vasoconstriction. Comparable elevations in community PM2.5 levels were not related to these outcomes, suggesting that specific components within personal and background ambient PM2.5 may elicit differing cardiovascular responses.

Early animal toxicological studies of air pollution had distinctively military or workplace themes. With the discovery that ambient air pollution episodes led to excess illness and death, there became an emergence of toxicological studies that focused on industrial air pollution encountered by the general public. Not only did the pollutants investigated evolve from ambient mixtures to individual pollutants but also the endpoints and outcomes evaluated became more sophisticated, resulting in our present state of the science. Currently, a large toxicological database exists for the effects of particulate matter and ozone, and we provide a focused review of some of the major contributions to the biological understanding for these two "criteria" air pollutants. A limited discussion of the toxicological advancements in the scientific knowledge of two hazardous air pollutants, formaldehyde and phosgene, is also included. Moving forward, the future challenge of air pollution toxicology lies in the health assessment of complex mixtures and their interactions, given the projected impacts of climate change and altered emissions on ambient conditions. In the coming years, the toxicologist will need to be flexible and forward thinking in order to dissect the complexity of the biological system itself, as well as that of air pollution in all its varied forms.

Ten or more members of the PE class of compounds are known to induce male fetal endocrine toxicity and postnatal reproductive malformations by disrupting androgen production during the sexual differentiation period of development. An early study conducted in the rat pubertal model suggested that dipentyl phthalate (DPeP) may be a more potent testicular toxicant than some more extensively studied phthalates. Regulatory agencies require dose-response and potency data to facilitate risk assessment; however, very little data are currently available for DPeP. The goal of this study was to establish a more comprehensive data set for DPeP, focusing on dose-response and potency information for fetal and postnatal male reproductive endpoints. We dosed pregnant rats on gestational day (GD) 17 or GD 14-18 and subsequently evaluated fetal testicular testosterone (T) production on GD 17.5 and GD 18, respectively. We also dosed pregnant rats on GD 8-18 and evaluated early postnatal endpoints in male offspring. Comparison of these data to data previously obtained under similar conditions for di (2-ethylhexyl) phthalate indicates that DPeP is approximately eightfold more potent in reducing fetal T production and two- to threefold more potent in inducing development of early postnatal male reproductive malformations. Additionally, fetal testicular T production was more sensitive to inhibitory effects of DPeP exposure than was gene expression of target genes involved in male reproductive development, supporting the use of this endpoint as a critical effect in the risk assessment process.

The extent and nature of the studies required under the traditional approach has limited the number of chemicals with published risk assessments. In this study, female mice were exposed for 13 weeks to multiple concentrations of five chemicals that were positive in a 2-year cancer bioassay. Traditional histological and organ weight changes were evaluated, and gene expression microarray analysis was performed on the target tissues. The histological, organ weight changes, and the original tumor incidences in the original cancer bioassay were analyzed using standard benchmark dose (BMD) methods to identify noncancer and cancer points of departure, respectively. The dose-related changes in gene expression were also analyzed using a BMD approach and the responses grouped based on cellular biological processes. A comparison of the transcriptional BMD values with those for the traditional noncancer and cancer apical endpoints showed a high degree of correlation for specific cellular biological processes. For chemicals with human exposure data, the transcriptional BMD values were also used to calculate a margin of exposure. The margins of exposure ranged from 1900 to 54,000. Both the correlation between the BMD values for the transcriptional and apical endpoints and the margin of exposure analysis suggest that transcriptional BMD values may be used as potential points of departure for noncancer and cancer risk assessment.

Toxicity of these sediment samples was measured using a 7-day Hyalella azteca survival and growth test. Sixty-five sites (14.5%) exhibited lethal toxicity, and 130 sites (29.1%) exhibited decreased growth. In the EMAP-GRE probabilistic sampling design, each sampled site had a weight associated with it that determined the length (and proportion) of the river represented by that sample point in the population. Weighted whole-river estimates indicated that of the 4721 river km sampled, sediment from 15.9 plus or minus 3.0% of the river (752 plus or minus 50km) were lethally toxic, 27.4 plus or minus 3.5% (1289 plus or minus 57km) were toxic by way of growth inhibition, and 40.0 plus or minus 3.7% (1887 plus or minus 68km) exhibited either lethal or growth toxicity. Selected toxic samples were analyzed for 21 pesticides, 20 polychlorinated biphenyl congeners, and 6 polybrominated diphenyl ether congeners. For all of the samples tested, the concentration levels of these analytes were mostly lower than known toxicity thresholds, and neither unionized ammonia concentration nor osmotic stress (as measured by conductivity) could account for the toxicity found in sediments. The spatial pattern of sediment toxicity cannot be readily explained by urbanization or agricultural land use at the subcatchment scale. We speculate that the distribution of toxic sediment is more likely due to a combination of localized sources, including polluted tributaries, and the redistribution of contaminated sediments from upriver. The sediment toxicity results from this study will be used, in combination with other sediment, biologic, and habitat metrics and indicators collected in the EMAP-GRE study, to help interpret and assess the condition of the Ohio, Upper Mississippi, and Missouri Rivers.

The ATUS is a large, on-going, cross-sectional survey of where Americans spend time and what activities they undertake in those locations. The data are reported as a series of sequential activities over a 24-h time period -- a "diary day" -- starting at 0400 hours. Between 12,000 and 13,000 surveys are obtained each year and the Bureau has plans to continue ATUS for the foreseeable future. The ATUS already has about 73,000 diary days of data, more than twice as many as that which currently exists in the US Environmental Protection Agency's (EPA) "Consolidated Human Activity Database" (CHAD) that the Agency uses for exposure modeling purposes. There are limitations for using ATUS in modeling human exposures to environmental pollutants. The ATUS does not report the location for a number of activities regarded as "personal." For 2006, personal activities with missing location information totaled 572min/day, on average, for survey participants: about 40% of their day. Another limitation is that ATUS does not distinguish between indoor and outdoor activities at home, two of the traditional locational demarcations used in human exposure modeling. This lack of information affects exposure estimates to both indoor and outdoor air pollutants and potentially affects non-dietary ingestion estimates for children, which can vary widely depending on whether or not a child is indoors. Finally, a detailed analysis of the work travel activity in a subsample from ATUS 2006 indicates that the coding scheme is not fully consistent with a CHAD-based exposure modeling approach. For ATUS respondents in this subsample who reported work as an activity, roughly 48% of their days were missing work travel at one or both ends of the work shift or reported within work-shift travel inconsistently. An extensive effort would be needed to recode work travel data from ATUS for EPA's exposure modeling purposes.

SSU rDNA clone libraries were generated from 16 concrete surfaces of manholes, a combined sewer overflow, and sections of a corroded sewer pipe. Of the 2457 sequences analyzed, Delta *a-, Delta *b-, Delta *g-, and Delta *d-Proteobacteria represented 15%, 22%, 11%, and 4% of the clones, respectively. Delta *b-Proteobacteria (47%) sequences were more abundant in the pipe crown than any of the other concrete surfaces. While 178 to 493 Operational Taxonomic Units (OTUs) were associated with the different concrete samples, only four sequences were shared among the different clone libraries. Bacteria implicated in concrete corrosion were found in the clone libraries while archaea, fungi, and several bacterial groups were also detected using group-specific assays. The results showed that concrete sewer biofilms are more diverse than previously reported. A more comprehensive molecular database will be needed to better study the dynamics of concrete biofilms.

Integrated assessment (IA) aims to bring diverse scientific, economics and social science expertise together to provide analysis and advice that comprehensively addresses all or at least many aspects of the climate change issue. IA methods have been applied to many areas of climate change providing insights into areas such as optimal timing of emission reductions, weighting of different greenhouse gases, or impacts of biofuel policies. Additionally, IAs have identified key uncertainties that should be priorities of future research, such as the need to understand oceanic heat uptake in order to better constrain climate sensitivity and predict future timing of temperature change. These assessments have also served to establish ongoing communication within the community of researchers, and between researchers and policy makers. In complex scientific issues it is often difficult for policy makers and the public to sort out conflicting scientific views, and an authoritative assessment process can provide consensus views on the issue, accepting that in some cases the "consensus" may be that some aspects of the issue remain unresolved. This review explores the history and applications of these IAs, and identifies avenues for future emphasis. We briefly review the whole field of IAs of climate change, but focus on the role of formal computational frameworks in IA models.

Fifty-two monthly collections (January--November) using trawls and seines occurred at 22 sites located in three adjacent bayous associated with the Pensacola Bay Estuary. Hurricanes Erin (Category 2) and Opal (Category 3) made landfall near the study area, and a state-wide entanglement net ban was initiated during the survey period. Approximately 585,000 fish were collected, which represented 80 species and 66 genera. The assemblages were dominated by estuarine-dependent and resident species similar to those commonly found in several nearby estuaries. Of these, Leiostomus xanthurus, Brevoortia patronus, Anchoa mitchilli, Lagodon rhomboides, and Menidia peninsulae composed 95%% or more of the total catch. The total number of species for each collection ranged from 8 to 23, total abundances varied from 140 to 14,315 individuals, and Shannon diversity index values (H'') were between 0.02 and 0.97. Mean species numbers and diversity index values were more consistent monthly than fish total abundance, which was influenced by seasonal occurrences of estuarine-dependent species. Hurricane effects were specific to the hurricane, structural parameter, species, and bayou. The posthurricane reductions in salinity (17%% to 69%%) and the few changes in fish abundance were usually temporary and within monthly and interannual variability. The resiliency of the fish assemblages to natural and anthropogenic stresses represents a survival advantage and readiness for future climatic change.

AN - 875716327; 201110818 AB - Politics and economics interact. As a consequence, political science textbooks must often relate to the economic dimension -- implicitly or explicitly. But we know very little about how these textbooks relate to economics. Are they merely unreflective customers of neoclassical economics or do they strive for a cross-disciplinary approach? An analysis of five American textbooks identifies two very different and concurrent interactions between politics and economics. The first is a theoretically conceived market economy in which market forces independently drive growth and create equilibrium, where politics has a rather secluded role. The second is the actually existing mixed economy, characterized by increased inequality, economic concentration, power, and environmental problems, influenced by a state forced to regulate. The problems of operating with such a dichotomy -- and possible solutions to it -- are being explored in the article. Adapted from the source document.

This publication describes and provides access to an easy-to-use coastal SST dataset for ecologists, biogeographers, oceanographers, and other scientists conducting research on nearshore marine habitats or processes. The data cover the Temperate Northern Pacific Ocean as defined by the "Marine Ecosystems of the World" (MEOW) biogeographic schema developed by The Nature Conservancy. The spatial resolution of the SST data is 4-km grid cells within 20 km of the shore. The data span a 29-year period--from September 1981 to December 2009. These SST data were derived from Advanced Very High Resolution Radiometer (AVHRR) instrument measurements compiled into monthly means as part of the Pathfinder versions 5.0 and 5.1 (PFSST V50 and V51) Project. The processing methods used to transform the data from their native Hierarchical Data Format Scientific Data Set (HDF SDS) to georeferenced, spatial datasets capable of being read into geographic information systems (GIS) software are explained. In addition, links are provided to examples of scripts involved in the data processing steps. The scripts were written in the Python programming language, which is supported by ESRI's ArcGIS version 9 or later. The processed data files are also provided in text (.csv) and Access 2003 Database (.mdb) formats. All data except the raster files include attributes identifying realm, province, and ecoregion as defined by the MEOW classification schema. JF - Open-File Report - U. S.

While the public health risk associated with such events is not well understood, quantitative microbial risk assessment can be used to estimate such risk. A conceptual model is provided and the state of knowledge, current assumptions, and challenges associated with the conceptual model parameters are presented. This review provides a characterization of the causes, magnitudes, durations and frequencies of low/negative pressure events; pathways for pathogen entry; pathogen occurrence in external sources of contamination; volumes of water that may enter through the different pathways; fate and transport of pathogens from the pathways of entry to customer taps; pathogen exposure to populations consuming the drinking water; and risk associated with pathogen exposure.

14365922 AB - Chlorination of drinking water yields hundreds of disinfection by-products (DBPs). Among the DBPs, four trihalomethanes (THMs; chloroform, bromodichloromethane, chlorodibromomethane, bromoform) and five haloacetic acids (HAAs; chloroacetic, dichloroacetic, trichloroacetic, bromoacetic, and dibromoacetic acid) are U.S. EPA regulated. We assessed the combined toxicity of these DBPs. F344 rats were treated with mixtures of the four THMs (THM4), the five HAAs (HAA5), or nine DBPs (DBP9; THM4+HAA5). Mixtures were administered in 10% Alkamuls registered EL-620 daily by gavage on gestation days 6-20. Litters were examined postnatally. All three mixtures caused pregnancy loss at less than or equal to 613 mu mol/kg/day. In surviving litters, resorption rates were increased in groups receiving HAA5 at 615 mu mol/kg/day and DBP9 at 307 mu mol/kg/day. HAA5 caused eye malformations (anophthalmia, microphthalmia) at less than or equal to 308 mu mol/kg/day. Thus, both HAAs and THMs contributed to DBP9-induced pregnancy loss. The presence of THMs in the full mixture, however, appeared to reduce the incidence of HAA-induced eye defects.

Organic (OC) and elemental (EC) carbon in PM2.5 ranged from 1.4-6.3 and 0.08-0.41 mu gCm super(-3), respectively, and concentrations measured above and below the pine canopy were in good agreement. Ambient OC was lower (3 mu gCm super(-3)) during warm humid periods. Radiocarbon analysis indicates that on average 83% (range 78-91%) of the PM2.5 carbon was derived from contemporary (biogenic VOC and biomass burning) sources. This is higher than previous estimates from urban and suburban sites, and in good agreement with recently published data from other rural sites throughout the U.S. The estimates of contemporary PM2.5 carbon may represent a lower limit for this site since the sampler was located above the center of a 30 meter diameter plot fumigated with 200ppm CO2 derived from fossil carbon sources. However, this effect is likely to be negligible. The regression relationship between OC/EC ratios and percent biogenic carbon in aerosol is very similar to those observed in recent summertime data from Tennessee and Florida. However, our values for both OC/EC and percent biogenic carbon are higher than those observed in the latter studies, likely due to the more rural character of the site. Simple box model estimates indicate that biogenic VOC (BVOC) emissions measured at the site provide sufficient reactive carbon sources to account for the observed levels of aerosol biogenic carbon. The magnitude and temporal pattern in the box model secondary organic aerosol estimates correlate well with the ambient aerosol carbon measurements. The model estimates of the relative contribution of isoprene, alpha -pinene, and beta -caryophyllene oxidation to PM2.5 carbon are in reasonable agreement with a study recently conducted at a nearby site where aerosol tracers of these compounds were quantitatively analyzed in ambient PM2.5. Pinic acid concentrations in the below-canopy PM2.5 during CELTIC (from another recently published study) similarly suggest a significant contribution of alpha -pinene oxidation to PM2.5 carbon. The biomass burning tracers potassium and levoglucosan yielded fire contribution estimates to PM2.5 consistent with their respective published emission factors. These estimates indicate that biomass burning accounted for 1 to 5% (0.015 to 0.30 mu gCm super(-3)) of the PM2.5 carbon during CELTIC.

To support policy-makers to implement programmes to reduce air pollution, the Veneto Region Environmental Protection Agency has set a state-of-the-art modelling system. Comparison between model results and measurements illustrates a fairly good agreement for NO2 annual mean concentration and deposition levels and daily maximum O 3 levels. The disagreement for PM10 results suggests the need of further improvements in the emission inventory and the meteorogical pre-processing. The aim of this application is to estimate atmospheric loads on the Venice lagoon through the model's deposition computation.

Measurements of mercury in blood from the National Health and Nutrition Examination Survey are frequently reported for "women of childbearing age," defined to be of ages 16-49 years. The intent is to represent prenatal chemical exposure, but blood mercury levels increase with age. Furthermore, women of different ages have different probabilities of giving birth. We evaluated options to address potential bias in biomonitoring summary statistics for women of childbearing age by accounting for age-specific probabilities of giving birth. We calculated median and 95th percentile levels of mercury, PCBs, and cotinine using these approaches: option 1: women aged 16-49 years without natality adjustment; option 2: women aged 16-39 years without natality adjustment; option 3: women aged 16-49 years, adjusted for natality by age; option 4: women aged 16-49 years, adjusted for natality by age and race/ethnicity. Among the three chemicals examined, the choice of option has the greatest impact on estimated levels of serum PCBs, which are strongly associated with age. Serum cotinine levels among Black non-Hispanic women of childbearing age are understated when age-specific natality is not considered. For characterizing in utero exposures, adjustment using age-specific natality provides a substantial improvement in estimation of biomonitoring summary statistics.

Seven sites derived their water from carbonate aquifers and one from fractured sandstone. Four of the sites were deemed "low-risk" based on prior monitoring of fecal indicators and factors such as presence of thick layers of overlying sediments. The remaining sites were deemed "high-risk." Enteric viruses (enterovirus and reovirus) were detected by cell culture at least once in seven of the eight wells or springs including all but one of the four low-risk sites. Viral RNA, however, was not detected in any of the samples by reverse transcription-polymerase chain reaction. Conventional indicators of microbial contamination (Escherichia coli and total coliform bacteria) were detected together with culturable viruses in seven of nine virus positive samples. Bacteroides, an alternative fecal indicator which has not previously been used in groundwater investigations, was also detected in all but one of the samples containing E. coli or total coliform bacteria, as well as in one sample where viruses were present in the absence of other bacterial indicators. The study highlights some of the challenges involved in surveys of virus occurrence and indicates that culturable enteric viruses in East Tennessee karst aquifers may be more widespread than previously observed in studies of karst aquifers in Pennsylvania (8%), the Ozark region of Missouri (<1%), or several other states covered in a national microbial water quality survey conducted by the U.S. Environmental Protection Agency (43%).

We compiled published data from wetland studies worldwide to estimate total Nr removal and to evaluate factors that influence removal rates. Over several orders of magnitude in wetland area and Nr loading rates, there is a positive, near-linear relationship between Nr removal and Nr loading. The linear model (null hypothesis) explains the data better than either a model of declining Nr removal efficiency with increasing Nr loading, or a Michaelis-Menten (saturation) model. We estimate that total Nr removal by major classes of wetlands in the contiguous U.S. is approximately 20-21% of the total anthropogenic load of Nr to the region. Worldwide, Nr removal by wetlands is roughly 17% of anthropogenic Nr inputs. Historical loss of 50% of native wetland area suggests an equivalent loss of Nr removal capacity. Expanded protection and large-scale restoration of wetlands should be considered in strategies to re-balance the global nitrogen cycle and mitigate the negative consequences of excess Nr loading.

We used two N removal models to predict NO sub(3)-N input and removal. NO sub(3)-N input ranged from 0.01 to 338kgkm super(-1) d super(-1) in the Upper Mississippi River to <0.01-54kgkm super(-1)d super(-1) in the Missouri River. Cumulative river network NO sub(3)-N input was 98700-101676Mgyear super(-1) in the Ohio River, 85961-89288Mgyear super(-1) in the Upper Mississippi River, and 59463-61541Mgyear super(-1) in the Missouri River. NO sub(3)-N output was highest in the Upper Mississippi River (0.01-329kgkm super(-1) d super(-1)), followed by the Ohio and Missouri Rivers (<0.01-236kgkm super(-1) d super(-1)) sub-basins. Cumulative river network NO sub(3)-N output was 97499Mgyear super(-1) for the Ohio River, 84361Mgyear super(-1) for the Upper Mississippi River, and 59200Mgyear super(-1) for the Missouri River. Proportional NO sub(3)-N removal (PNR) based on the two models ranged from <0.01 to 0.28. NO sub(3)-N removal was inversely correlated with stream order, and ranged from <0.01 to 8.57kgkm super(-1)d super(-1) in the Upper Mississippi River to <0.001-1.43kgkm super(-1 )d super(-1) in the Missouri River. Cumulative river network NO sub(3)-N removal predicted by the two models was: Upper Mississippi River 4152 and 4152Mgyear super(-1), Ohio River 3743 and 378Mgyear super(-1), and Missouri River 2277 and 197Mgyear super(-1). PNR removal was negatively correlated with both stream order (r=-0.80-0.87) and the percent of the catchment in agriculture (r=-0.38-0.76).

Burial of aerobic sediments into an anaerobic environment may release metals, such as through reductive dissolution of metal oxyhydroxides. Mining-impacted aerobic streambed sediments collected from North Fork Clear Creek, Colorado were held under anaerobic conditions for four months. Eh, pH, and concentrations of Cd, Cu, Fe, Mn, and Zn (filtered at 1.5 mu m, 0.45 mu m, and 0.2 mu m), sulfate, and dissolved organic carbon (DOC) were monitored in stream water/sediment slurries. Two sediment size fractions were examined (2 mm-63 mu m and <63 mu m). Sequential extractions evaluated the mineral phase with which metals were associated in the aerobic sediment. Released Cu was re-sequestered within 5 weeks, while Fe and Mn still were present at 16 weeks. Mn concentration was lower than in the initial stream water at and beyond 14 weeks for the smaller sized sediment. Cd was not released from either sediment size fraction. Zn was released at early times, but concentrations never exceeded those present in the initial stream water and all was re-sequestered over time. The greatest concentrations of Cu, Fe, Mn, and Zn were associated with the Fe/Mn reducible fraction. Sulfate and Fe were strongly correlated (r = 0.90), seeming to indicate anaerobic dissolution of iron oxy-hydroxy-sulfate minerals. DOC and sulfate were strongly correlated (r = 0.81), with iron having a moderately strong correlation with DOC (r = 0.71). Overall concentrations of DOC, sulfate, Cu, Fe, and Zn and pH were significantly higher (p < 0.05) in the water overlying the small sized sediment samples, while the concentrations of Mn released from the larger sized sediment samples were greater.

Sensitivity to aconitine-induced arrhythmia has been employed to examine the factors that increase the risk of such dysfunction. We used aconitine to test whether a single exposure to diesel exhaust (DE) would increase the risk of arrhythmia being triggered in hypertensive rats. We hypothesised that DE exposure increases the risk of arrhythmia due to sensory irritation during and after inhalation. Spontaneously hypertensive rats surgically implanted with radiotelemeters were exposed to 150 mu g/m3 of DE or filtered air for 4 h. Arrhythmogenesis was assessed 24 h later in urethane-anaesthetised animals by continuous intravenous infusion of aconitine while heart rate (HR) and electrocardiogram (ECG) were monitored. Rats exposed to DE had lower HR when compared to air-exposed animals. Exposure to DE resulted in significantly shorter PR intervals, and significantly prolonged corrected QT (QTc) and corrected JT (JTc) when compared to air exposure. Sensitivity to arrhythmia was measured as the threshold dose of aconitine required to produce ventricular premature beats (VPB), ventricular tachycardia (VT) and ventricular fibrillation (VF). Rats exposed to DE successively developed VPB's, VT, and VF at significantly lower doses of aconitine than air-exposed animals. Pre-exposure treatment of rats exposed to DE with a transient receptor potential A1 (TRPA1) antagonist prevented the heightened sensitivity to aconitine-induced arrhythmia. These findings suggest that a single exposure to DE increases arrhythmogenic sensitivity. This heightened sensitivity may be mediated by activation of TRPA1 on airway sensory nerves, which are particularly sensitive to inhaled irritants. (This abstract does not reflect EPA policy.)

Using farm-level survey data from the Brazilian Amazon, I estimate a production function to assess the value of forest fallow and test whether it provides local externalities to agricultural production. Soil quality controls, instrumental variables, and spatial econometric approaches help address endogeneity issues. I use GIS data on external forest cover at the farm level and model the hydrological externality as an upstream-to-downstream process. The estimated parameters indicate that fallow contributes significantly to productivity both on farm and downstream. In addition, most farms allocate sufficient land to fallow, accounting for both the value of hydrological spillovers and the opportunity cost of land left out of cultivation. These results suggest that farming communities may have some self-interest in preserving forest cover locally-a finding that may bolster policy efforts aimed at conserving tropical forests for their global public goods.

AN - 821199993; 21184572 AB - The objective of this work is to present a critical review of the application of the tissue residue approach (TRA) in ecological risk and/or impact assessment (ERA) of chemical stressors and environmental criteria development. A secondary goal is to develop a framework for integrating the TRA into ecological assessments along with traditional, exposure concentration-based assessment approaches. Although widely recognized for its toxicological appeal, the utility of the TRA in specific applications will depend on numerous factors, such as chemical properties, exposure characteristics, assessment type, availability of tissue residue-response data, and ability to quantify chemical exposure. Therefore, the decision to use the TRA should include an evaluation of the relative strengths, limitations, and uncertainties among exposure and residue-based methods for characterizing toxicological effects. Furthermore, rather than supplanting exposure concentration-based toxicity assessments, the TRA can be highly effective for evaluating and reducing uncertainty when used in a complementary manner (e.g., when evaluating multiple lines of evidence in field studies). To address limitations with the available tissue residue-response data, approaches for extrapolating residue-based toxicity data across species, tissues, and exposure durations are discussed. Some of these approaches rely on predicted residue-response relationships or toxicological models that have an implicit residue-response basis (e.g., biotic ligand model). Because risk to an organism is a function of both its exposure potential and inherent sensitivity (i.e., on a residue basis), bioaccumulation models will be required not only for translating tissue residue criteria into corresponding water and sediment criteria, but also for defining the most vulnerable species in an assemblage (i.e., highly exposed and highly sensitive species). Application of the TRA in ecological assessments and criteria development are summarized for bioaccumulative organic chemicals, TBT, and in situ bioassays using bivalve molluscs.

AN - 821199163; 20963851 AB - Animals have evolved diverse protective mechanisms for responding to toxic chemicals of both natural and anthropogenic origin. From a governmental regulatory perspective, these protective responses complicate efforts to establish acceptable levels of chemical exposure. To explore this issue, we considered vertebrate endocrine systems as potential targets for environmental contaminants. Using the hypothalamic-pituitary-thyroid (HPT), hypothalamic-pituitary-gonad (HPG), and hypothalamic-pituitary-adrenal (HPA) axes as case examples, we identified features of these systems that allow them to accommodate and recover from chemical insults. In doing so, a distinction was made between effects on adults and those on developing organisms. This distinction was required because endocrine system disruption in early life stages may alter development of organs and organ systems, resulting in permanent changes in phenotypic expression later in life. Risk assessments of chemicals that impact highly regulated systems must consider the dynamics of these systems in relation to complex environmental exposures. A largely unanswered question is whether successful accommodation to a toxic insult exerts a fitness cost on individual animals, resulting in adverse consequences for populations. Mechanistically based mathematical models of endocrine systems provide a means for better understanding accommodation and recovery. In the short term, these models can be used to design experiments and interpret study findings. Over the long term, a set of validated models could be used to extrapolate limited in vitro and in vivo testing data to a broader range of untested chemicals, species, and exposure scenarios. With appropriate modification, Tier 2 assays developed in support of the U.S. Environmental Protection Agency's Endocrine Disruptor Screening Program could be used to assess the potential for accommodation and recovery and inform the development of mechanistically based models. © 2010 SETAC.

AN - 821198698; 21180825 AB - 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 also discuss nanoscale zero-valent 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.

In the experiment, polyester resin wastewater was treated by Fe-C micro-electrolysis by changing the iron dosage, the ratio of iron to carbon (Fe/C, w/w) and initial pH of wastewater. Then based on the orthogonal experiment, single factor method was used to find out the best parameters of Fe-C micro-electrolysis. The result showed that the original pH of wastewater ranked first, followed by the iron dosage and the ratio of iron to carbon. The optimal pretreatment process conditions were room temperature, initial pH =2.0, iron dosage = 100 g/L, Fe/C = 1/1(w/w), aeration reaction time =2h. Under the optimal process conditions, its BOD sub(5)/COD sub(cr) level increased from 0.17 to 0.33. In addition, the COD sub(cr) removal efficiency could approach 50.91% after Fe-C micro-electrolysis treatment, so the organic loading of subsequent biological treatment unit could be decreased sharply.

The results presented here, utilising combinations of dual carbon isotope analysis, provides conclusive evidence of a dominant biogenic organic fraction to organic aerosol over biologically active oceans. In particular, the NE Atlantic, which is also subjected to notable anthropogenic influences via pollution transport processes, was found to contain 80% organic aerosol matter of biogenic origin directly linked to plankton emissions. The remaining carbonaceous aerosol was of terrestrial origin. By contrast, for polluted air advected out from Europe into the NE Atlantic, the source apportionment is 30% marine biogenic, 40% fossil fuel, and 30% continental non-fossil fuel. The dominant marine organic aerosol source in the atmosphere has significant implications for climate change feedback processes.

Results show that the mean annual historical rainfall and runoff, averaged over the entire region, are 516 and 55 mm, respectively. There is considerable uncertainty in the global climate modelling (GCM) of rainfall response in the region to global warming. The majority of GCMs show a decrease in the mean annual rainfall and the median estimate indicates that future mean annual runoff in the region in [approx]2030 relative to [approx]1990 will be lower by 0-20% in the southern parts, no change to a slight reduction in the eastern parts and higher by 0-20% in the northwest corner. Averaged across the entire region, the median estimate is a 5% decrease in the mean annual runoff and the extreme estimates range from a 14% decrease to a 10% increase in mean annual runoff. This is the first comprehensive study on the hydrological impacts of climate change done in NSW that covers the entire state. Outputs from this study are being used to underpin the hydrology for a number of major climate change impact studies that are presently underway across NSW. The results and output datasets from this study will be available through a web interface and they can be used by all state government agencies and industries in NSW to plan for and adapt to the impacts of climate change.

The objective of this study was to quantify and describe the distribution of the 36 molds that make up the Environmental Relative Moldiness Index (ERMI). Materials and Methods . As part of the 2006 American Healthy Homes Survey, settled dust samples were analyzed by mold-specific quantitative PCR (MSQPCR) for the 36 ERMI molds. Each species' geographical distribution pattern was examined individually, followed by partitioning analysis in order to identify spatially meaningful patterns. For mapping, the 36 mold populations were divided into disjoint clusters on the basis of their standardized concentrations, and First Principal Component (FPC) scores were computed. Results and Conclusions . The partitioning analyses failed to uncover a valid partitioning that yielded compact, well-separated partitions with systematic spatial distributions, either on global or local criteria. Disjoint variable clustering resulted in seven mold clusters. The 36 molds and ERMI values themselves were found to be heterogeneously distributed across the United States of America (USA).

This necessitates excluding important variables from the model when applying standard multiple or multivariate regression analyses. In this paper, we present the results of applying PLS to explore relationships among biotic indicators of surface water quality and landscape conditions accounting for the above problems. Available field sampling and remotely sensed data sets for the Savannah Basin are used. We were able to develop models and compare results for the whole basin and for each ecoregion (Blue Ridge, Piedmont, and Coastal Plain) in spite of the data constraints. The amount of variability in surface water biota explained by each model reflects the scale, spatial location, and the composition of contributing landscape metrics. The landscape-biota model developed for the whole basin using PLS explains 43% and 80% of the variation in water biota and landscape data sets, respectively. Models developed for each of the three ecoregions indicate dominance of landscape variables which reflect the geophysical characteristics of that ecoregion.

The Emission Scenario Projection (ESP) methodology focuses on energy production and use, the principal sources of many air pollutants. Emission growth factors for energy system categories are calculated using the MARKAL energy system model. Growth factors for non-energy sectors are based on economic and population projections. These factors are used to grow a 2005 emissions inventory through 2050. The approach is demonstrated for two emission scenarios for the United States. Scenario 1 extends current air regulations through 2050, while Scenario 2 adds a hypothetical CO sub(2) mitigation policy. Although both scenarios show significant reductions in air pollutant emissions through time, these reductions are more pronounced in Scenario 2, where the CO sub(2) policy results in the adoption of technologies with lower emissions of both CO sub(2) and traditional air pollutants. The methodology is expected to play an important role within an integrated modeling framework that supports the US EPA's investigations of linkages among emission drivers, climate and air quality.

The composition of oil samples used in dispersion experiments was systematically manipulated by varying the relative concentrations of the saturates, aromatics, resins, and asphaltenes (SARA) fractions. Forward stepwise linear regression was used with a generalized linear model that included main effects and two-factor interactions to evaluate the effects of oil composition on chemical dispersion. Limited sensitivity analysis was used to determine whether the significant effects were strongly dependent on the specific combination of responses observed in these experiments or insensitive to small changes within the range of variation that was observed. The concentration of the aromatics fraction and the saturates-resins interaction exerted statistically significant, positive effects on dispersion effectiveness (p 20 mu m) droplets. Higher concentrations of the saturates fraction favored the entrainment of floating oil as small and medium-sized droplets, whereas the aromatics-asphaltenes interaction reduced the amount of oil present as small droplets. Aromatics-asphaltenes interaction increased the overall diameter of mean volume (DMV) of the dispersed oil droplets, and the saturates-asphaltenes interaction reduced it.

Effects of viscosity and interfacial tension were investigated by testing three crude oils (Arabian Light, Mars, and Lloyd) at two dispersant-to-oil ratios (DOR; 1:100 and 1:25) and three energy dissipation rates (0.00075, 0.016, and 0.16 W/kg). Dispersion effectiveness (i.e., fraction entrained as droplets in the water column) of all three oils was maximal at a mixing energy of 0.016 W/kg, which is similar to the energy dissipation rate in the surface layer of the open ocean. For Arabian Light and Mars, dispersion effectiveness was affected by DOR only at the lowest mixing energy, but it was proportional to DOR at all mixing energies for the more viscous oil, Lloyd. Droplet-size distributions were multimodal for all oil-dispersant combinations that were tested, indicating the involvement of multiple droplet-formation mechanisms. Diameter of mean volume of the major droplet-size modes was not sensitive to changes in mixing energy or DOR, but the fraction of dispersed oil in each mode was affected by these factors as well as by the oil type. Under all dispersion conditions (DOR and mixing energy), droplets produced by dispersion of more viscous oils were larger than those produced by less viscous oils.

ToxCast Phase I tested 309 well-characterized chemicals in more than 500 assays for a wide range of molecular targets and cellular responses. Of the 309 environmental chemicals in Phase I, 256 were linked to high-quality rat multigeneration reproductive toxicity studies in the relational Toxicity Reference Database. Reproductive toxicants were defined here as having achieved a reproductive lowest-observed-adverse-effect level of less than 500 mg kg-1 day-1. Eight-six chemicals were identified as reproductive toxicants in the rat, and 68 of those had sufficient in vitro bioactivity to model. Each assay was assessed for univariate association with the identified reproductive toxicants. Significantly associated assays were linked to gene sets and used for the subsequent predictive modeling. Using linear discriminant analysis and fivefold cross-validation, a robust and stable predictive model was produced capable of identifying rodent reproductive toxicants with 77% plus or minus 2% and 74% plus or minus 5% (mean plus or minus SEM) training and test cross-validation balanced accuracies, respectively. With a 21-chemical external validation set, the model was 76% accurate, further indicating the model's potential for prioritizing the many thousands of environmental chemicals with little to no hazard information. The biological features of the model include steroidal and nonsteroidal nuclear receptors, cytochrome P450 enzyme inhibition, G protein-coupled receptors, and cell signaling pathway readouts-mechanistic information suggesting additional targeted, integrated testing strategies and potential applications of in vitro HTS to risk assessment.

Recent models suggest that wetlands and other small water bodies may serve as important long-term sinks of eroded C, receiving approximately 30% of all eroded material in the US. To better understand the role of seasonally-saturated wetlands in sequestering eroded C, we examined the spatial and temporal dynamics of C and sediment accumulation in a 13-year-old constructed wetland used to treat agricultural runoff. The fate of C sequestered within deposited sediment was modeled using point-sampling, remote sensing, and geostatistics. Using a spatially-explicit sampling design, annual net rates of sedimentation and above-ground biomass were measured during two contrasting years (vegetated (2004) vs. non-vegetated (2005)), followed by collection of sediment cores to the antecedent soil layer, representing 13 years of sediment and C accumulation. We documented high annual variation in the relative contribution of endogenous and exogenous C sources, as well as absolute rates of sediment and C deposition. This annual variation, however, was muted in the long-term (13 yr) sediment record, which showed consistent vertical patterns of uniform C distribution ( approximately 14 g kg (super -1) ) and delta (super 13) C signatures in high depositional environments. This was in contrast to low depositional environments which had high levels of surface C enrichment (20-35 g kg (super -1) ) underlain by C depleted (5-10 g kg (super -1) ) sediments and an increasing delta (super 13) C signature with depth indicating increased decomposition. These results highlight the importance of sedimentation in physically protecting soil organic carbon and its role in controlling the long-term C concentration of seasonally-saturated wetland soils. While significant enrichment of surface sediments with endogenous C occurred in newly deposited sediment (i.e., 125 kg m (super 2) in 2004), fluctuating cycles of flooding and drying maintained the long-term C concentration at the same level as inflowing sediment (i.e., 14 g kg (super -1) ), indicating no additional long-term storage of endogenous C. These results demonstrate that constructed flow-through wetlands can serve as important sinks for eroded C and sediment in agricultural landscapes, however, additional C sequestration via enrichment from endogenous sources may be limited in seasonally-saturated wetlands due to rapid decomposition during drying cycles.

Our objective was to assess the influence of land use and watershed geomorphic characteristics on low-flow variability in the southern Blue Ridge Mountains of North Carolina and Georgia. Ten minute interval discharge data for 35 streams (in watersheds from 3 to 146 km (super 2) ) were measured for two late summer low-flow seasons, coinciding with a severe drought period in the southeastern United States. Three low-flow metrics were calculated (1 and 7 day minimum flows and 1st percentile flow) for each low-flow season (5 August to 12 November 2007 and 1 August to 12 November 2008). A comprehensive suite of watershed characteristics, including factors of topography, channel network morphometry, soils, land use, and precipitation were used in multiple regression analysis of low-flow variability among the 35 watersheds. Additionally, low flows in groups of lower- and higher-forest cover watersheds were compared. Drainage density, areal coverage of colluvium, topographic variability (as slope standard deviation), and percent of the channel network as first order stream emerged as the most important variables for explaining low-flow variability. Watershed forest cover demonstrated a consistent, significant positive relationship with low flows, despite the higher evapotranspiration rates associated with forest compared with other land covers and despite the relatively small range of disturbance in this study area. This highlights the importance of infiltration and recharge under undisturbed land cover in sustaining low flows, and it bears noteworthy implications for environmental flows and water resource sustainability.

Our objective was to determine if MS can be used as an intrinsic bioremediation indicator due to the activity of iron-reducing bacteria. A contaminated and an uncontaminated core were retrieved from a site contaminated with crude oil near Bemidji, Minnesota and subsampled for MS measurements. The contaminated core revealed enriched MS zones within the hydrocarbon smear zone, which is related to iron-reduction coupled to oxidation of hydrocarbon compounds and the vadose zone, which is coincident with a zone of methane depletion suggesting aerobic or anaerobic oxidation of methane is coupled to iron-reduction. The latter has significant implications for methane cycling. We conclude that MS can serve as a proxy for intrinsic bioremediation due to the activity of iron-reducing bacteria iron-reducing bacteria and for the application of geophysics to iron cycling studies.

Some species, such as Aeromonas hydrophila, can cause disease in humans. For this survey, 293 United States public water systems were selected using random sampling, stratified by water source and system type. Water samples were collected during one year from three sites (six samples per site) in each system. Temperature, pH, turbidity, total and free chlorine were measured using standard methods. Aeromonads were detected in 130 of 5,042 valid samples (2.6%) from 42 (14.3%) systems using the ampicillin-dextrin agar with vancomycin culture method with oxidase, trehalose and indole confirmation tests. Concentrations of aeromonads in positive samples were 0.2 to 880 (median 1.6) colony-forming units (CFU) per 100 mL. Adjusted odds ratios of Aeromonas detection were 1.6 (95% confidence limits 1.0, 2.5) during the summer season, 3.3 (1.8, 6.2) for turbidity above 0.5 nephelometric units and 9.1 (3.5, 24) at 0 mg/L compared with 0.25 mg/L total chlorine. Geographic region, system size and type of water source were not significant predictors of Aeromonas detection in multivariate regression analysis. The results of this survey demonstrate the importance of maintaining adequate residual chlorine and low turbidity for preventing drinking water contamination with aeromonads.

We have designed a strategy for standardizing different local data sets containing evidence of the presence or absence of permafrost into an inventory for the entire European Alps.

The paper outlines key elements of a corporate sustainability strategy and provides individual examples from various companies. The audience for this paper includes companies that are early in the sustainability process as well as companies that are interested in improving or expanding their established sustainability strategy. A corporate sustainability strategy is a multi-faceted strategy that provides multiple benefits to the company. The elements of a corporate sustainability strategy are grouped into these categories: (1) set strategic direction; (2) improve operational performance; (3) improve value chain performance; and (4) relate effectively to internal and external stakeholders.

We apply a new model, Visualizing Ecosystems for Land Management Assessments (VELMA), to elucidate how hillslope and catchment-scale processes control stream discharge in a small Pacific Northwest catchment. VELMA is a spatially distributed ecohydrology model that links hydrological and biogeochemical processes within watersheds. The study site is WS10 of the H.J. Andrews LTER, a 10 ha forested catchment clearcut in 1975. Simulated and observed daily streamflow are in good agreement for both the pre- (1969-1974) and postharvest (1975-2008) periods (Nash-Sutcliffe efficiency = 0.807 and 0.819, respectively). One hundred scenarios, where harvest amounts ranged from 2% to 100% were conducted. Results show that (1) for the case of a 100% clearcut, stream discharge initially increased by approximately 29% or 345 mm but returned to preclearcut levels within 50 years, and (2) annual streamflow increased at a near linear rate of 3.5 mm year (super -1) for each percent of catchment harvested, irrespective of location. Thereafter, to assess the impact of harvest location on stream discharge, 20 harvest scenarios were simulated, where harvest amount was fixed at 20% but harvest location varied. Results show that the streamflow response is strongly sensitive to harvest distance from the stream channel. Specifically, a 20% clearcut area near the catchment divide resulted in an average annual streamflow increase of 53 mm, whereas a 20% clearcut near the stream resulted in an average annual streamflow increase of 92 mm.

Multitank models simulate ZOB and hillslope hydrological response, while kinematic wave models predict saturation overland runoff from riparian zones and route inputs from ZOB and riparian corridors through the channel. The model was parameterized and tested in the Hitachi Ohta Experiment Watershed, Japan. Tank models were parameterized for a 6 month period from May to October 1992, and these models were then tested for the same 6 month period in 1993. In ZB, with relatively shallower soils, total outflow for the 6 month period in 1993 was underpredicted by 25%. Better predictions were obtained for outflow from FA (deeper soils; -17%) and the entire catchment (-5%). Total runoff from the channel and riparian area depends on the ratio of this area to the total catchment area because this corridor is assumed to be saturated at all times. Stormflow response from ZOB was limited during relatively dry conditions and increased substantially during wetter conditions, especially in ZB, which has shallower soils (1.4 m of average); such effects were diminished in FA (deeper soils) and hillslopes. Outflow from ZB had the highest proportion of rapid flow, while slower flow dominates outflow from FA and hillslopes; these different responses appear to be mainly associated with soil depth and topography. Groundwater recharge, estimated by leakage from the lowermost tank in the models, was as high as 61 mm week (super -1) from ZB, with lesser recharge from other geomorphic components (18-21 mm week (super -1) ). These spatially explicit simulations provide a simpler approach to the greater data demands of distributed hydrologic models without compromising process function.

Investigations conducted from 1993 to 1999 by State and Federal agencies confirmed the detection of PCE in the shallow aquifer, as well as the detection of the organic solvent trichloroethylene (TCE) and various inorganic compounds, but the source of the groundwater contamination was not determined. In May 2000 the U.S. Environmental Protection Agency proposed that the site, called the Capital City Plume (CCP) Site, be a candidate for the National Priorities List. Between 2000 and 2007, numerous site-investigation activities also did not determine the source of the groundwater contamination. In 2008, additional assessments were conducted at the CCP Site to investigate the potential source area, contamination pathway, and the probable release history of the chlorinated-solvent-contaminated groundwater. The assessments included the collection of (1) pore water in 2008 from the hyporheic zone of a creek using passive-diffusion bag samplers; (2) tissue samples in 2008 and 2009 from trees growing in areas of downtown Montgomery characterized by groundwater contamination and from trees growing in riparian zones along the Alabama River and Cypress Creek; and (3) groundwater samples in 2009 and 2010. The data collected were used to investigate the potential source area of contaminants detected in groundwater, the pathway of groundwater contamination, and constraints on the probable contaminant-release history.

Excess nitrogen inputs are a major cause of eelgrass loss in the marine environment. Here we describe the results of a study aimed at quantifying the extent of eelgrass as a function of predicted watershed-derived nitrogen loading for small-to-medium-sized shallow estuaries in New England. Findings confirm that reduced extent of eelgrass corresponds to increased loading of nitrogen to this class of estuary. At lower levels of nitrogen loading (>50Kgh super(-1) 1yr super(-1)), eelgrass extent is variable and is likely controlled by other ecosystem factors unrelated to water quality. At higher loading rates, eelgrass coverage decreases markedly, with essentially no eelgrass at loading levels >100Kgh super(-1)yr super(-1).

One putative mechanism may be through modification of cell-surface costimulatory molecules. We examined whether changes in expression of costimulatory molecules on circulating cells are associated with ambient levels of fine PM [aerodynamic diameter less than or equal to 2.5 mu m (PM2.5)] in a susceptible population of diabetic individuals. Twenty subjects were studied for 4 consecutive days. Daily measurements of PM2.5 and meteorologic data were acquired on the rooftop of the exam site. Circulating cell-surface markers that mediate innate immune and inflammatory responses were assessed by flow cytometry on each day. Sensitivity analysis was conducted on glutathione S-transferase M1 (GSTM1) genotype, body mass index, and glycosylated hemoglobin A1c (HbA1c) levels to determine their role as effect modifiers. Data were analyzed using random effects models adjusting for season, weekday, and meteorology. We found significantly increased monocyte expression (mean fluorescent intensity) of CD80, CD40, CD86, HLA-DR, and CD23 per 10- mu g/m3 increase in PM2.5 at 2- to 4-day lag times after exposure. These findings were significantly higher in obese individuals, in individuals with HbA1c > 7%, and in participants who were GSTM1 null. Exposure to PM2.5 can enhance antigen-presenting cell phenotypes on circulating cells, which may have consequences in the development of allergic or autoimmune diseases. These effects are amplified in diabetic individuals with characteristics that are associated with insulin resistance or with oxidative stress.

At steady state, arsenic body burdens in As3mt knockout mice were 16 to 20 times greater than in wild-type mice. During the post dosing clearance period, arsenic body burdens declined in As3mt knockout mice to ~35% and in wild-type mice to ~10% of steady-state levels. Urinary concentration of arsenic was significantly lower in As3mt knockout mice than in wild-type mice. At steady state, As3mt knockout mice had significantly higher fractions of the body burden of arsenic in liver, kidney, and urinary bladder than did wild-type mice. These organs and lung had significantly higher arsenic concentrations than did corresponding organs from wild-type mice. Inorganic arsenic was the predominant species in tissues of As3mt knockout mice; tissues from wild-type mice contained mixtures of inorganic arsenic and its methylated metabolites. Diminished capacity for arsenic methylation in As3mt knockout mice prolongs retention of inorganic arsenic in tissues and affects whole body clearance of arsenic. Altered retention and tissue tropism of arsenic in As3mt knockout mice could affect the toxic or carcinogenic effects associated with exposure to this metalloid or its methylated metabolites.

AN - 821195267; 21073185 AB - Emissions from the in situ burning of oil in the Gulf of Mexico after the catastrophic failure of the Deepwater Horizon drilling platform were sampled for polychlorinated dibenzodioxins and polychlorinated dibenzofurans (PCDD/PCDF). A battery-operated instrument package was lofted into the plumes of 27 surface oil fires over a period of four days via a tethered aerostat to determine and characterize emissions of PCDD/PCDF. A single composite sample resulted in an emission factor of 2.0 ng toxic equivalency (TEQ) per kg of carbon burned, or 1.7 ng TEQ per kg of oil burned, determined by a carbon balance method. Carbon was measured as CO(2) plus particulate matter, the latter of which has an emission factor of 0.088 kg/kg carbon burned. The average plume concentration approximately 200-300 m from the fire and about 75-200 m above sea level was <0.0002 ng TEQ/m(3).

AN - 812137699; 20851754 AB - Biomarkers are useful exposure surrogates given their ability to integrate exposures through all routes and to reflect interindividual differences in toxicokinetic processes. Also, biomarker concentrations tend to vary less than corresponding environmental measurements, making them less-biasing surrogates for exposure. In this article, urinary PAH biomarkers (namely, urinary naphthalene [U-Nap]; urinary phenanthrene [U-Phe]; 1-hydroxypyrene [1-OH-Pyr]; and 1-, (2+3)-, 4-, and 9-hydroxyphenanthrene [1-, (2+3)-, 4-, and 9-OH-Phe]) were evaluated as surrogates for exposure to hot asphalt emissions using data from 20 road-paving workers. Linear mixed-effects models were used to estimate the within- and between-person components of variance for each urinary biomarker. The ratio of within- to between-person variance was then used to estimate the biasing effects of each biomarker on a theoretical exposure-response relationship. Mixed models were also used to estimate the amounts of variation in Phe metabolism to individual OH-Phe isomers that could be attributed to Phe exposure (as represented by U-Phe concentrations) and covariates representing time, hydration level, smoking status, age, and body mass index. Results showed that 1-OH-Phe, (2+3)-OH-Phe, and 1-OH-Pyr were the least-biasing surrogates for exposure to hot asphalt emissions, and that effects of hydration level and sample collection time substantially inflated bias estimates for the urinary biomarkers. Mixed-model results for the individual OH-Phe isomers showed that between 63% and 82% of the observed biomarker variance was collectively explained by Phe exposure, the time and day of sample collection, and the hydration level, smoking status, body mass index, and age of each worker. By difference, the model results also showed that, depending on the OH-Phe isomer, a maximum of 6-23% of the total biomarker variance was attributable to differences in unobserved toxicokinetic processes between the workers. Therefore, toxicokinetic processes are probably less influential on urinary biomarker variance than are exposures and observable covariate effects. The methods described in this analysis should be considered for the selection and interpretation of biomarkers as exposure surrogates in future exposure investigations.

Two competing effects may account for the variation in disinfection kinetic parameters: (i) increasing kinetics (disinfection rate constant [k] increased, lag coefficient [b] decreased) with increasing phosphate concentration and (ii) decreasing kinetics (k decreased, b increased) with increasing ionic strength. The results support development of a standard medium for evaluating disinfection kinetics in drinking water.

Wastewater is treated through primary clarification, with flows in excess of the hydraulic capacity of the secondary system being directed to effluent disinfection. Before disinfection, the primary clarified effluent is "blended" with effluents that have been treated through the secondary system. The combined or "blended" effluents are then disinfected before being discharged to receiving waters. This study evaluated the effectiveness of chlorine to disinfect blended effluents. Experiments were conducted at bench-scale on primary and secondary effluents and three ratios of primary to secondary effluent (1:9, 3:7, and 5:5) from three publicly owned treatment works. Results from this study found that blending 10% or more primary effluent with secondary reduces the efficacy of chlorine disinfection, and coliphage survived chlorine disinfection better than bacterial indicator organisms. A simple empirical model for predicting indicator organism densities following chlorine disinfection was developed using data from this research.

Methods: Elevation in thyroid stimulating hormone (TSH), which may reflect reduced thyroxin concentration, was assessed in 497,458 newborns in California in 1998. A total of 800 perchlorate water measurements were used to classify California communities as exposed (>5 mu g/L) or unexposed. Results were stratified by age at TSH collection because of the normal post-birth TSH surge, and because water sources and perchlorate exposure can change soon after birth. Results: In TSH samples collected within 24 hours of birth, the odds ratio for a TSH greater than 25 mu U/mL in exposed communities was 1.53 (P < 0.0001). After 24 hours, the odds ratio for a TSH more than the 95th percentile was 1.27 (P < 0.0001). Conclusion: These findings suggest that perchlorate is associated with increased neonatal TSH levels.

A range of future climate scenarios is available for the conterminous United States that have been developed based on widely used international greenhouse gas emissions storylines. Climate scenarios derived from these emissions storylines have not been matched with logically consistent land use/cover maps for the United States. This gap is a critical barrier to conducting effective integrated assessments. This study develops novel national scenarios of housing density and impervious surface cover that are logically consistent with emissions storylines. Analysis of these scenarios suggests that combinations of climate and land use/cover can be important in determining environmental conditions regulated under the Clean Air and Clean Water Acts. We found significant differences in patterns of habitat loss and the distribution of potentially impaired watersheds among scenarios, indicating that compact development patterns can reduce habitat loss and the number of impaired watersheds. These scenarios are also associated with lower global greenhouse gas emissions and, consequently, the potential to reduce both the drivers of anthropogenic climate change and the impacts of changing conditions. The residential housing and impervious surface datasets provide a substantial first step toward comprehensive national land use/land cover scenarios, which have broad applicability for integrated assessments as these data and tools are publicly available.

Recent analyses of the bottled mineral waters quality have not included systematic examinations of micro-components present in these waters. Based on the analyses of the bottled mineral waters (EuroGeoSurveys Geochemistry Expert Group), it has been observed that the water quality is greatly influenced by the chemical composition of igneous intrusions, regardless of the fact that the analyzed waters have been taken from different aquifers (Neogene sediments, limestone, flysch, schist). Bottled waters in Serbia are usually HCO (sub 3) , with Na or Ca like dominant cation, and in large range regarding TDS. In some bottled waters high content of micro-components and trace elements was recorded. The analyses of mineral waters prove the direct dependence between the hydrochemical composition of waters and complex geological properties in which the formation and movement of waters have been taking place, throughout the geological history.

However, the GOM region has the highest rate of wetland loss in the USA. Protection and management of these vital GOM habitats are critical to sustainable shrimp fisheries. Brown shrimp (Farfantepenaeus aztecus) are a major component of GOM fisheries. We present an approach for estimating the areal extent of suitable habitat for post-larval and juvenile brown shrimp in Mobile Bay, Alabama, using an existing habitat suitability index model for the northern GOM calculated from probabilistic survey of water quality and sediment data, land cover data, and submerged aquatic vegetation coverages. This estuarine scale approach is intended to support targeted protection and restoration of these habitats. These analyses indicate that approximately 60% of the area of Mobile Bay is categorized as suitable to near optimal for post-larval and juvenile shrimp and 38% of the area is marginally to minimally suitable. We identify potential units within Mobile Bay for targeted restoration to improve habitat suitability.

Litter thickness, litter nitrogen (N) content, and soil N mineralization rates often remain elevated long after inputs cease, clouding the prospects that plant community diversity and composition would recover should N inputs be reduced. Here we determined how N cycling, litter accumulation, and recruitment limitation influenced community recovery following cessation of long-term N inputs to prairie-like grasslands. We alleviated each of these potential inhibitors through a two-year full-factorial experiment involving organic carbon addition, litter removal, and seed addition. Seed addition had the largest effect on increasing seedling and species numbers and may be necessary to overcome long-term burial of seeds of target perennial grassland species. Litter removal increased light availability and bare sites for colonization, though it had little effect on reducing the biomass of competing neighbors or altering extractable soil N. Nonetheless, these positive influences were enough to lead to small increases in species richness within one year. We found that, although C addition quickly altered many factors assumed favorable for the target community (decreased N availability and biomass of nearby competitors, increased light and site availability), these changes were insufficient to positively impact species richness or seedling numbers over the experimental duration. However, only carbon addition had species-specific effects on the existing plant community, suggesting that its apparent limited utility may be more a result of slow recovery under ambient recruitment rather than from a lack of a restorative effect. There were dramatic interactions among treatments, with the positive effects of litter removal largely negated by carbon addition, and the positive effects of seed addition generally amplified by litter removal. It remains unclear whether each mechanism explored here will induce community recovery, but over different temporal scales. Long-term monitoring will help resolve these remaining questions. Regardless, our results suggest that reversal of species loss and compositional shifts from N deposition in prairies may be more inhibited by habitat fragmentation, recruitment limitation, and long-term suppression of fire than from continued effects of elevated N.

Field sampling was conducted during daytime high tides, and was quantitative, stratified-by-habitat, randomized, and estuary-wide. More than 10 000 nekton specimens belonging to 64 taxa were collected in 454 samples during 10 sampling periods, each approximately one-month-long (from June to November), over 3 years (1998-2000). Non-metric multidimensional scaling analyses revealed annually recurring across-habitat patterns in total nekton Bray-Curtis similarity. Two-way (habitat, year) analyses of variance revealed annually recurring across-habitat patterns on 10 indicators of nekton-habitat quality and preference. Total nekton species richness, abundance, and biomass were, respectively, on average, 8 , 25 , and 25 greater in eelgrass, 4 , 6 , and 5 greater in mud shrimp, and 2 , 3 , and 2 greater in ghost shrimp, than in sand habitat. Our findings validate the ecological relevance of our habitats to nekton, and suggest they can serve as elements in ecological periodic tables of nekton habitat usage.Original Abstract: Nous avons compare la similarite de Bray-Curtis du necton total, ainsi que la richesse specifique, l'abondance et la biomasse moyennes du necton total, des poissons et des crabes, de meme que l'abondance des crevettes dans quatre habitats intertidaux (a zostere marine (Zostera marina), a crevettes fouisseuses des vases (Upogebia pugettensis), a crevettes fantomes fouisseuses (Neotrypaea californiensis) et de sable sans vegetation) dans un estuaire de la cote americaine de la region pacifique du nord-ouest. L'echantillonnage sur le terrain a ete fait durant les marees hautes de jour et comportait des echantillons quantitatifs, stratifies par habitat, aleatoires et couvrant tout l'estuaire. Nous avons recolte plus de 10 000 individus du necton appartenant a 64 taxons dans 454 echantillons durant dix periodes d'echantillonnage d'environ un mois (juin a novembre) sur trois annees (1998-2000). Des analyses de cadrage multidimensionnel non metrique montrent des patrons de similarite de Bray-Curtis dans le necton total entre les habitats qui se repetent d'annee en annee. Des analyses de variance a deux criteres de classification (habitat, annee) revelent des patrons recurrents d'annee en annee a travers les habitats de dix indicateurs nectoniques de la qualite et de la preference des habitats. La richesse specifique, l'abondance et la biomasse du necton total sont en moyenne respectivement 8 , 25 et 25 plus grandes dans les habitats a zostere, 4 , 6 et 5 plus grandes dans les habitats a crevettes des vases et 2 , 3 et 2 plus grandes dans les habitats a crevettes fantomes que dans les habitats sablonneux. Nos observations confirment la pertinence de nos habitats pour le necton et indiquent qu'ils pourraient servir d'elements dans des tableaux periodiques ecologiques de l'utilisation faite par le necton.

Of the 240 benthic invertebrate taxa identified, 19 were non-indigenous, including 8 first detection records for this system: New Zealand mud snail Potamopyrgus antipodarum; African/Asian-origin cladoceran Daphnia lumholtzi; Eurasian-origin amphipod Echinogammarus ischnus; Eurasian-origin bivalves Dreissena bugensis, Pisidium henslowanum and Pisidium supinum; and possibly range expanding oligochaetes Paranais frici and Pristina acuminata. Dreissenids were by far the most abundant NIS. Several other NIS were also common, but others were detected in only a few of the > 200 samples taken. Non-indigenous amphipods and Dreissena were most frequently detected in sweep net and colonization plate samples of littoral vegetation, while NIS oligochaetes, gastropods, and non-dreissenid bivalves were most frequently detected in ponar and bottom sled samples of sediments. Our findings confirm that this major shipping port remains a NIS "hotspot" and emphasize that regular surveys covering a range of habitats with multiple sampling gears and thorough taxonomic effort are needed to detect and monitor non-indigenous species.

AN - 815959802; 21121378 AB - Nanomaterials have very unique chemical and physical properties that suggest potential health hazards, but limited health and safety information exists for engineered nanomaterials. This review identifies a need for expanding efforts for addressing health and safety concerns in nanotechnology development and in nanotoxicology of engineered nanomaterials. The efforts include research to generate data for safety evaluation, toxicologic evaluation of potential human health effects, risk assessment to support risk-management decision-making, and regulations development to protect human health and the environment. The federal government's current understanding is that existing statutory authorities are adequate to address oversight of nanotechnology and its applications. On the other hand, the present review identifies weaknesses in the current research efforts and inadequacies in existing regulations. A collaborative effort involving multidisciplinary groups is a key element to address the related needs and issues. While federal agencies with regulatory responsibilities are looked upon to develop and implement sound policies and regulations to protect public health and the environment, state agencies may be required to initiate policies which rapidly incorporate new innovations and address public concerns. To address current and futures need related to nanotechnology, the responsible state agencies need to fill the information gaps and address the health and environmental issues. In California, activities have been initiated, but legislative authority and resources are required to provide risk assessment and health protection in an efficient and timely manner.

AN - 815549171; 20727709 AB - The present study examines the postnatal reproductive development of male rats following prenatal exposure to an atrazine metabolite mixture (AMM) consisting of the herbicide atrazine and its environmental metabolites diaminochlorotriazine, hydroxyatrazine, deethylatrazine, and deisopropylatrazine. Pregnant Long-Evans rats were treated by gavage with 0.09, 0.87, or 8.73mg AMM/kg body weight (BW), vehicle, or 100mg ATR/kg BW positive control, on gestation days 15-19. Preputial separation was significantly delayed in 0.87 mg and 8.73mg AMM-exposed males. AMM-exposed males demonstrated a significant treatment-related increase in incidence and severity of inflammation in the prostate on postnatal day (PND) 120. A dose-dependent increase in epididymal fat masses and prostate foci were grossly visible in AMM-exposed offspring. These results indicate that a short, late prenatal exposure to mixture of chlorotriazine metabolites can cause chronic prostatitis in male LE rats. The mode of action for these effects is presently unclear. Published by Elsevier Inc. JF - Reproductive toxicology (Elmsford, N.Y.)

AN - 812135800; 20886546 AB - Chronic exposure to inorganic arsenic (iAs) is associated with the development of benign and malignant human skin lesions including nonmelanoma skin cancers. The precise arsenical form(s) responsible for this carcinogenic effect are unknown, although trivalent inorganic arsenic (iAs(III)) and two of its toxic metabolites, monomethylarsonous acid (MMA(III)) and methylarsinous acid (DMA(III)), are attractive candidates. In an effort to better understand and compare their toxic effects in the skin, we compared the global gene expression profiles of normal human epidermal keratinocytes (NHEKs) exposed to varying noncytotoxic/slightly cytotoxic concentrations of iAs(III), MMA(III), and DMA(III) for 24 h. Exposure to each arsenical treatment group exhibited a dose effect in the number of altered genes and the magnitude of expression change in NHEKs. The most significant gene expression changes associated with iAs(III) and MMA(III) exposure were consistent with several key events believed to be important to As-driven skin carcinogenesis, namely induction of oxidative stress, increased transcript levels of keratinocyte growth factors, and modulation of MAPK and NF-κB pathways. At both comparable arsenical concentrations and comparable NHEK toxicity, greater potential carcinogenic effects were observed in MMA(III)-exposed NHEKs than those exposed to iAs(III), including involvement of more proinflammatory signals and increased transcript levels of more growth factor genes. In contrast, none of these above-mentioned transcriptional trends were among the most significantly altered functions in the DMA(III) treatment group. This study suggests the relative capacity of each of the tested arsenicals to drive suspected key events in As-mediated skin carcinogenesis is MMA(III) > iAs(III) with little contribution from DMA(III). © 2010 Wiley-Liss, Inc.

The argument for changing the name of IAEMS and its affiliated societies. AN - 812135609; 20850562 AB - We identify trends over the past decades in membership in societies affiliated with the International Association of Environmental Mutagen Societies (IAEMS), and we also highlight findings in a recent review by Claxton et al. [Environ Health Perspect, in press] regarding the numbers of papers published per year using genetic toxicology assays. These analyses reveal a decline or at best a static level of membership in IAEMS-affiliated societies, as well as a decline in the number of papers published per year using genetic toxicology assays-with the exception of those using comet assays, which already have begun to plateau. In contrast, toxicogenomics and computational toxicology are becoming increasingly prominent relative to environmental mutagenesis research in most research institutes, reflecting the ascendancy of these areas of environmental toxicology. We conclude that changing the name of IAEMS and its affiliated societies to reflect these changes might enhance membership and publication by welcoming a broader range of scientists into these societies. Although various names are possible, we think that changing the name of these societies to "Environmental Genomics Society" may help to make our societies more attractive to a broader range of scientists, resulting in an increase in membership and an acceleration of the incorporation of genomic methods into environmental research.

AN - 812128783; 20602262 AB - A growing body of evidence from epidemiological and toxicological studies provides a strong link between exposure to ambient particulate matter (PM) of varying size and increased cardiovascular and respiratory morbidity and mortality. This study was designed to evaluate the cardiopulmonary effects of ambient coarse, fine, and ultrafine particles collected in Chapel Hill, NC. Mice were exposed to each size fraction by oropharyngeal instillation. Twenty-four hours later, pulmonary inflammation was assessed by bronchoalveolar lavage and cardiac injury was measured using a Langendorff cardiac perfusion preparation. Recovery of post-ischemic left ventricular developed pressure and infarct size were measured as indeces of cardiac ischemia/reperfusion injury. Coronary flow rate was measured before, during, and after ischemia. We demonstrate that coarse PM caused the most significant pulmonary inflammatory responses. In contrast, hearts from ultrafine-exposed mice had significantly lower post-ischemic functional recovery and greater infarct size, while hearts from coarse and fine PM-exposed mice had no significant responses to ischemia/reperfusion. The coronary flow rate was significantly reduced in the ultrafine PM group. This study shows that exposure of mice to coarse PM results in significant pulmonary toxicity while ultrafine PM appears to enhance cardiac ischemia/reperfusion injury.

However, to adequately link air and watershed models for wet deposition estimates, each model's temporal and spatial representation of precipitation needs to be consistent. We explore how precipitation implemented within the Community Multi-Scale Air Quality Model (CMAQ) model algorithms, and multiple spatially-explicit precipitation datasets that could be used to improve the CMAQ model deposition estimates, links with the standard precipitation sources used to calibrate watershed models (i.e., rain gage data) via modeled water fluxes. Simulations are run using a grid-based watershed mercury model (GBMM) in two watersheds. Modeled monthly runoff suggests that multiple resolution Parameter-elevations Regressions on Independent Slopes Model (PRISM) and National Multi-sensor Precipitation Analysis Stage IV (NPA) data generate similar monthly runoff estimates, with comparable or greater accuracy when evaluated against stream gage data than that produced by the base rain gage data. However, across longer time periods, simulated water balances using 36aakm Pennsylvania State University/National Center for Atmospheric Research mesoscale model (MM5) data are similar to that of base data.

The present study tested the hypothesis that perinatal triclosan exposure of dams decreases thyroxine in dams and offspring prior to weaning. Pregnant Long-Evans rats received triclosan by oral gavage (0-300 mg/kg/d) in corn oil from gestational day (GD)6 through postnatal day (PND)21. Serum was obtained from pups on PND4, 14, and 21, and from dams on PND22. Serum thyroxine (T4) was reduced 31% in dams on PND22. In pups, a unique pattern of hypothyroxinemia was observed; serum T4 decreased 27% in PND4 pups with no significant reduction observed on PND14 or PND21. Comparable reductions of approximately 30% in serum T4 at 300 mg/kg/d for dams and PND4 neonates and a lack of effect at PND14 and PND21 suggest that toxicokinetic or toxicodynamic factors may have contributed to a reduced exposure or a reduced toxicological response during the lactation period.

Objectives of work presented here include establishing the toxicity of a variety of silver nanoparticles (AgNPs) to Daphnia magna neonates, assessing the applicability of a commonly used bioassay for testing AgNPs, and determining the advantages and disadvantages of multiple characterization techniques for AgNPs in simple aquatic systems. Daphnia magna were exposed to a silver nitrate solution and AgNPs suspensions including commercially available AgNPs (uncoated and coated), and laboratory-synthesized AgNPs (coated with coffee or citrate). The nanoparticle suspensions were analyzed for silver concentration (microwave acid digestions), size (dynamic light scattering and electron microscopy), shape (electron microscopy), surface charge (zeta potentiometer), and chemical speciation (X-ray absorption spectroscopy, X-ray diffraction). Toxicities of filtered (100 nm) versus unfiltered suspensions were compared. Additionally, effects from addition of food were examined. Stock suspensions were prepared by adding AgNPs to moderately hard reconstituted water, which were then diluted and used straight or after filtration with 100-nm filters. All nanoparticle exposure suspensions, at every time interval, were digested via microwave digester and analyzed by inductively coupled argon plasma-optical emission spectroscopy or graphite furnace-atomic absorption spectroscopy. Dose-response curves were generated and median lethal concentration (LC50) values calculated. The LC50 values for the unfiltered particles were (in [mu]g/L): 1.1 +/- 0.1-AgNO sub(3); 1.0 +/- 0.1-coffee coated; 1.1 +/- 0.2-citrate coated; 16.7 +/- 2.4 Sigma Aldrich Ag-nanoparticles (SA) uncoated; 31.5 +/- 8.1 SA coated. LC50 values for the filtered particles were (in [mu]g/L): 0.7 +/- 0.1-AgNO sub(3); 1.4 +/- 0.1-SA uncoated; 4.4 +/- 1.4-SA coated. The LC50 resulting from the addition of food was 176.4 +/- 25.5-SA coated. Recommendations presented in this study include AgNP handling methods, effects from sample preparation, and advantages/disadvantages of different nanoparticle characterization techniques.

This paper deals with the argument by adopting a hydrological model called Forecasting of Landslides Induced by Rainfall (FLaIR). The model is applicable for forecasting recurrent landslides and it is based on the identification of a mobility function Y(.) that links the occurrence of a slope movement to the antecedent rainfall. Once the mobility function is defined, it is possible to define its critical values, the exceeding of which indicates that new mobilizations could occur. The FLaIR model has been used to study some phenomena that happened in Lanzo Valleys, a Western Alps sector of the Piedmont region (Northern Italy) where slope debris flows are the predominant landslide type. The study has led to the development of an early warning system, called MoniFLaIR, for real-time monitoring and forecasting of slope hazard. This article describes some details of the system and its performance.

This study sought to determine if DE exposure could affect the severity of an ongoing influenza infection in mice, and examine if this could be modulated with antioxidants. BALB/c mice were treated by oropharyngeal aspiration with 50 plaque forming units of influenza A/HongKong/8/68 and immediately exposed to air or 0.5 mg/m3 DE (4 hrs/day, 14 days). Mice were necropsied on days 1, 4, 8 and 14 post-infection and lungs were assessed for virus titers, lung inflammation, immune cytokine expression and pulmonary responsiveness (PR) to inhaled methacholine. Exposure to DE during the course of infection caused an increase in viral titers at days 4 and 8 post-infection, which was associated with increased neutrophils and protein in the BAL, and an early increase in PR. Increased virus load was not caused by decreased interferon levels, since IFN- beta levels were enhanced in these mice. Expression and production of IL-4 was significantly increased on day 1 and 4 p.i. while expression of the Th1 cytokines, IFN- gamma and IL-12p40 was decreased. Treatment with the antioxidant N-acetylcysteine did not affect diesel-enhanced virus titers but blocked the DE-induced changes in cytokine profiles and lung inflammation. We conclude that exposure to DE during an influenza infection polarizes the local immune responses to an IL-4 dominated profile in association with increased viral disease, and some aspects of this effect can be reversed with antioxidants.

AN - 763473478; 20879747 AB - Synthetic nanomagnetite has been suggested as a potential reactant for the in situ treatment of contaminated groundwater. Although the application of magnetite nanoparticles for environmental remediation is promising, a full understanding of particle reactivity has been deterred by the propensity of the nanoparticles to aggregate and become colloidally unstable. Attractive magnetic interactions between particles are partially responsible for their aggregation. In this study, we characterized the magnetic behavior of magnetite by determining the saturation magnetization, coercivity, remanent magnetization, susceptibility, and blocking temperature of synthetic magnetite using a superconducting quantum interference device (SQUID). We show how these properties vary in the presence of surface-associated solutes such as tetramethylammonium (TMA(+)) and ferrous (Fe(II)) cations. More importantly, because magnetite readily reacts with O(2) to produce maghemite, we analyzed the effect of oxidation on the magnetic properties of the particles. Because maghemite has a reported magnetic saturation that is less than that of magnetite, we hypothesized that oxidation would decrease the magnitude of the magnetic attractive force between adjacent particles. The presence of TMA(+) and Fe(II) caused a change in the magnetic properties of magnetite potentially because of alterations in its crystalline order. Magnetite oxidation caused a decrease in saturation magnetization, resulting in less significant magnetic interactions between particles. Oxidation, therefore, could lead to the decreased aggregation of magnetite nanoparticles and a potential enhancement of their colloidal stability.

AN - 764493269; 20949951 AB - Sludges generated at a wastewater treatment plant (WWTP) in Decatur, Alabama have been applied to agricultural fields for more than a decade. Waste-stream sources to this WWTP during this period included industries that work with fluorotelomer compounds, and sludges from this facility have been found to be elevated in perfluoroalkylates (PFAs). With this knowledge, the U.S. Environmental Protection Agency collected soil samples from sludge-applied fields as well as nearby "background" fields for PFA analysis. Samples from the sludge-applied fields had PFAs at much higher concentrations than in the background fields; generally the highest concentrations were perfluorodecanoic acid (≤ 990 ng/g), perfluorododecanoic acid (≤ 530 ng/g), perfluorooctanoic acid (≤ 320 ng/g), and perfluorooctane sulfonate (≤ 410 ng/g). Contrasts in PFA concentration between surface and deeper soil samples tended to be more pronounced in long-chain congeners than shorter chains, perhaps reflecting relatively lower environmental mobilities for longer chains. Several PFAs were correlated with secondary fluorotelomer alcohols (sec-FTOHs) suggesting that PFAs are being formed by degradation of sec-FTOHs. Calculated PFA disappearance half-lives for C6 through C11 alkylates ranged from about 1 to 3 years and increase with increasing chain-length, again perhaps reflecting lower mobility of the longer-chained compounds.

A number of conditions resulted in the deterioration in pervaporation performance of these el s. Long-term exposure to simple binary ethanol-water mixtures resulted in slow declines in ethanol permeability, water permeability, and selectivity. Treating the particles by quenching them in linear short-chain alcohols immediately after calcination protected the el against this performance decline. In addition, rapid and dramatic reductions in both ethanol permeability and selectivity occurred when the el s were exposed to a centrifuged yeast fermentation broth. Exposure to a clarified acetone/n-butanol/ethanol (ABE) fermentation broth also resulted in marked reductions in performance, albeit less severe and not as rapid as with the yeast broth. The effect of the broths was not easily reversed. The most effective regeneration scheme was soaking the el in 100% n-butanol, which fully recovered the original performance.

The present experiment sought to determine whether subchronic inhalation of toluene caused persistent behavioral changes in rats. Adult male Long-Evans rats inhaled toluene vapor (0, 10, 100, or 1000ppm) for 6h/day, 5days/week for 13weeks and were evaluated on a series of behavioral tests beginning 3days after the end of exposure. Toluene delayed appetitively-motivated acquisition of a lever-press response, but did not affect motor activity, anxiety-related behavior in the elevated plus maze, trace fear conditioning, acquisition of an appetitively-motivated visual discrimination, or performance of a visual signal detection task. Challenges with acute inhalation of toluene vapor (1200-2400ppm for 1h) and injections of quinpirole (0.01-0.03mg/kg) and raclopride (0.03-0.10mg/kg) revealed no toluene-induced latent impairments in visual signal detection. These results are consistent with a pattern of subtle and inconsistent long-term effects of daily exposure to toluene vapor, in contrast to robust and reliable effects of acute inhalation of the solvent.

In critical situations, such as emergency response incidents, communication is imperative between scientists and non-scientists. Information must be provided in a format that can be easily found, widely understood, and not misinterpreted. In addition, information must be accurate and quick. The ash spill in Harriman, Tennessee at the Tennessee Valley Authority's (TVA) Kingston Fossil Fuel Plant provides an educational example to break down EPA's communication efforts and how it evolved during the time critical removal phase of the clean-up. The lessons learned from this environmental clean-up can provide benefits to other scientists' work needing to involve other scientific and non-scientific groups. On December 22, 2008 at 1 am, a dike surrounding the dredge cell containing coal ash (mainly fly ash) at TVA Kingston broke, releasing 5.4 million cubic yards (cys) of coal ash to approximately 300 acres including the Emory River and adjacent Swan Pond Embayment. Three homes were condemned and 40 additional properties sustained damage. Utilities, roadways, and railroad were disrupted and several residents were evacuated from the area until gas lines were restored. TVA, EPA, TDEC (state agency), and local emergency management responded to the incident. An abundance of information began emerging from the incident from media, government agencies, and environmental activist groups. With the overwhelming amount of information and inconsistents, residents were confused. Residents didn't know where to find the most accurate, up-to-date material or which agency/group was most accurate. Centralizing information into a trusted source was needed. As a result, one of the first time critical tasks accomplished was establishing a website where documents approved and released by EPA would be viewable by anyone. Within a month, the website became the first link produced by search engines when wanting to get information about the TVA Kingston ash spill. The popularity of the website gave scientists at the site a portal to communicate effectively with the community (scientific and non-scientific). As the site clean-up progressed, the website evolved around it displaying photographs, videos, scientific studies, work plans, and maps.

We observed a broad, spatial pattern in the carbon stable isotope ratio ( delta super(13)C); downriver enrichment in particulate organic carbon and aquatic vegetation delta super(13)C, as well as pelagic, benthic and littoral invertebrate delta super(13)C, reflected isotope mixing along the river-lake transition zone. Fishes with similarly enriched delta super(13)C were used to identify benthopelagic and littoral trophic pathways. River and Lake Superior organic matter (OM) sources contributed to both pathways. Differences between the delta super(13)C in fishes and invertebrate prey revealed that fish production was supported at multiple spatial scales. The result was that the food web specific to any location along the transition zone incorporated multiple OM sources from across the watershed.

A pilot study on the use of lichens to assess impacts from oil sands processing was conducted on samples collected near the world-class Athabasca deposits in Alberta, Canada during 2002. The lichen samples were collected on N-S and E-W transects at distances from as little as 5 km to as much as 120 km from the mining and processing sites. Analysis of the Hypogymnia physodes samples for a suite of trace elements and lead isotope ratios using sector field ICP-MS indicated that elements incorporated into the lichen tissue reflected source differences, proximity to processing sites, as well as the inherent biogeochemistry of the lichens. Preliminary source apportionment analysis indicate three main element groupings including a geogenic wind-blown dust factor (Al, Ce, Cr, Fe, La, Nd, Sc and Ti), an oil processing signature (S, N, Mo, Ni and V) and an element association related to the nutrient needs of lichens (Ba, Cd, K, Mn, P, Rb and Zn) that is likely related to wildfires and stemflow. The samples collected beyond 50 km from the mining and processing sites cluster into a lead isotope grouping with a (super 207) Pb/ (super 206) Pb ratio of 0.8650 and a (super 208) Pb/ (super 206) Pb ratio near 2.105. This grouping likely reflects the regional background lead isotope ratio signature. The lowering of the (super 207) Pb / (super 206) Pb and (super 208) Pb/ (super 206) Pb ratios as one approaches the mining operations indicates other Pb sources, likely related to the oil sands processing, are contributing to the Pb isotope signature. An exponential decrease in concentration of the geogenic grouping of metals versus distance from the mining sites, suggests that most of the wind-blown dust was emitted as coarse particles from abrasion processes. Near source concentrations of metals with an oil signature are less enhanced than the geogenic materials, reflecting emission and deposition of smaller diameter particles at greater distances from processing stack sources. The mining and oil processing impacts are superimposed over the elemental signature that reflects the nutrient needs of the lichens. Based on proximal versus distal differences in lichen tissue geochemistry, anthropogenic impacts may be influencing nutrient processing by lichens.

An MMI is a sum of several standardized numeric variables or metrics, each representing a different attribute of a biological assemblage. Many researchers believe that highly correlated metrics should not be included in the same MMI because they convey redundant information. To seek evidence for or against this belief, I compared the performance of 1,000 MMIs created for each of eight existing data sets by randomly resampling metrics from sets of previously identified candidates. An MMI's performance was measured by its precision and its ability to detect differences between assemblages sampled in independently assessed reference and impacted streams. Across the 1,000 MMIs, precision decreased with increasing mean correlation magnitude for seven of the eight data sets. For seven of the data sets, multiple linear regressions fitted to each set of 1,000 MMIs predicted a decrease in MMI detection ability as the mean correlation magnitude between metrics increased, after adjusting for the average responsiveness of individual metrics to the difference between reference and impacted conditions. However, similar regressions showed that the size of the largest correlation between any two metrics in an MMI had little or no effect on its detection ability. Thus, minimizing the mean of metric correlations is more effective than the widespread practice of setting an upper correlation limit when optimal MMI performance is desired. Finally, an MMI had originally been built for each data set by selecting one set of individually best metrics. In 23 of 24 assessments, 5-100% of randomly selected MMIs outperformed the original MMIs. Because individually best metrics rarely yielded a best-performing summed index, I recommend assessing multiple candidate MMIs, rather than just multiple candidate metrics, when developing a new MMI.

In overburden groundwater at a site within this belt in north-central Massachusetts, As has been reported at levels up to 7.6 mg/L. Bedrock at the site consists of Silurian Central Maine Terrane metasediments intruded by the Devonian Ayer granodiorite and Chelmsford granite. Exchange of hydrothermal fluids between these lithologies during intrusion and later deformation, faulting, and metamorphism resulted in crystallization of arsenic-bearing minerals, including arsenopyrite. Quaternary deglaciation and unloading dilated joint systems in the bedrock, allowing increased exposure of the mineralogy to meteoric water. Several arsenopyrite alteration products (e.g., scorodite), of varying solubilities, precipitated on fracture surfaces and along grain boundaries between major phases. In the emerging conceptual model for this site, groundwater is recharged in bedrock uplands and moves downgradient through the fracture network, becoming increasingly reducing as it moves along a flow path. Arsenic dissolved from arsenopyrite and arsenic-bearing alteration phases in bedrock remains in solution until the groundwater discharges to lowland areas hydraulically downgradient. In these adjacent lowlands, glacial sand and gravel overburden lies above the bedrock. When the reducing water reaches more oxidizing conditions, As-sorbing hydrous ferric oxides (HFO) precipitate out on the aquifer solids, resulting in accumulation of As in the deep overburden aquifer. A large landfill at this site, now closed and capped, imposed reducing conditions, and As is mobilized into groundwater by reductive dissolution of the HFO. The presence of elevated As in groundwater is consistent with arsenic-bearing phases generated in granitoids at depth during regional metamorphism, which were subsequently altered, and are being solubilized at present by the circulation of shallow groundwater through varying redox environments. This scenario is supported by geochemical and petrographic studies of the granitoids and the occurrence of the highest groundwater and soil arsenic concentrations in the adjacent deep overburden.

The district is located in the headwaters of the Arkansas River watershed in the Sawatch Mountains Range in central Colorado, approximately 120 km southwest of Denver. The 3385 meter long Leadville Mine Drain Tunnel (LMDT) was completed in 1952 to create a free-draining tunnel to dewater existing and future mine workings. Since 1952 mining has been mostly discontinued in the Leadville District and the physical condition of the LMDT, which discharges approximately 82 l/s, has deteriorated and entry into the tunnel is not possible. Roof falls have resulted in blockages which can cause water to pool up, increasing the hydraulic head and presenting a potential blowout problem. Water discharges from the LMDT via the portal and via wells constructed in the tunnel. The LMDT is located within Operable Unit 6 of the California Gulch Superfund site. The US EPA has completed a rigorous hydrogeologic characterization aimed at developing a sound conceptual understanding of the hydrologic, geologic, geochemical and physical conditions that control inflow of ground water and mine pool water to the underground workings associated with the LMDT and the outflow of mine water from these workings. The investigations presented here include hydrogeologic mapping, interpretation of water chemistry data, water level data, time-drawdown test data, tunnel tracing and isotopic tracer analysis. The results of this investigation indicate that the LMDT drains only a small volume of mine pool water and a very large volume of regional bedrock water. These understandings have been used to design a source control system that could be used to control and manage the groundwater intercepted by the LMDT and the mine pools that are connected to the LMDT.

Dose-response relationships based on internal concentrations (tissue residues) are limited. The present study reports Hg dose-response curves for early life stage and juvenile or adult fish based on published tissue-residue toxicity studies. These curves rely primarily on endpoints that can be directly related to mortality, such as survival, reproductive success, and lethal developmental abnormalities. These lethality-equivalent endpoints were linked using the common metric of injury. Uncertainties and potential applications of this mercury dose-response curve are discussed. Major uncertainties include lab to field extrapolations, biological endpoints selected by investigators, interspecific extrapolations, and the paucity of published early life stage residue (dose)-response information. To the extent this curve is based exclusively on laboratory toxicity tests and does not consider other potentially sensitive and ecologically important biological endpoints (e.g., growth and behavior), the magnitude of the adverse effects predicted by the curve may be underestimated.

The biocidal nature, protein fouling resistance, and fouling release properties of CNT-NCs render them the perfect material for biofouling prevention. At the same time, the cytotoxicity of CNT-NCs can be reduced before applying them as substrates to promote biofilm formation in environmental biotechnology applications. This paper reviews the potential prospects of CNT-NCs to accomplish two widely varying objectives in environmental engineering applications: (i) preventing biofouling, and (ii) promoting the formation of desirable biofilms on materials surface. This paper addresses practical issues such as costs, risks to human health, and ecological impacts that are associated with the application, development and commercialization of CNT-NC technology.

A HPLC-MS/MS method was developed using direct injection (DI) of larger volumes and a polar endcapped reversed-phase (RP) column to measure drug components in water samples belonging to the cocaine group, opiates, amphetamine-like stimulants and metabolites thereof. After validation, including sensitivity, linearity, recovery, precision and matrix effect studies, most drugs could be detected with limits of quantitation (LOQ) of 20ngL super(-1) in wastewater (WW) and 0.2ngL super(-1) in surface water. The major substances found in influents and effluents were cocaine (COC), benzoylecgonine (BE), morphine (MO), methadone (MD) and its main metabolite 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) with concentrations up to 2 mu gL super(-1), followed by codeine (COD) and the amphetamines which ranged between 20 and 400ngL super(-1). Except for MO, COD and EDDP levels were generally lower in the effluents. River and lake water contained trace amounts of mainly BE, MD and EDDP from the high pg L super(-1) to the low ngL super(-1) level. Monitoring COC and BE levels over 11 consecutive days in influents and effluents suggests a consumption preference on week-end days. Finally, measuring an influent after a major music event revealed that sewage treatment plants (STPs) are exposed, for a limited period of time, to high concentration peaks of COC and BE as well as amphetamine-like stimulants such as ecstasy (MDMA).

Western North Atlantic watershed budgets suggest that the export of human-derived N from estuaries to shelf waters off the east coast of the US may be significant; however, models based on water inputs and estimates of upwelling of deepwater nutrients to surface waters of the mid-Atlantic bight indicate that estuarine N may be a relatively minor component of the overall shelf N budget. Stable N isotope ratios could provide a means to assess the relative input of anthropogenic N to shelf waters, particularly since dissolved N from human sources has elevated delta 15N values (range: 7-30). We collected particulate material from surface shelf waters off the US east coast from 2000 to 2005 at near-shore sample sites proximal to the mouth of six estuaries and corresponding sites farther offshore. Near-shore (mean 33.7 km from estuary mouth) delta 15N values ranged from 5.5 to 7.7 Offshore values (mean 92.4 km from estuary mouth) were consistently lower than near-shore sites (average 4.7 plus or minus 1.0 versus 6.8 plus or minus 1.1), suggesting different N sources to near and offshore stations. Near-shore regions are often more productive, as mean monthly chlorophyll-a concentrations from the sea-viewing wide field-of-view sensor (SeaWiFS) were significantly higher at near-shore sites near the mouth of three of the six estuaries. A mass balance using a concentration-dependent mixing model with chlorophyll-a concentrations as a surrogate for dissolved inorganic nitrogen can account for all of the nitrogen at near-shore sites south of Cape Cod with estuarine nitrogen estimated to contribute 45-85% of the nitrogen to the near-shore surface particulate material. Our results support the hypothesis that estuarine nitrogen is influencing continental shelf ecosystems, and also provide preliminary evidence of the spatial extent of its influence on shelf waters in the mid-Atlantic bight.

Trenbolone is an androgenic steroidal hormone used primarily as a growth stimulant in the animal feedstock industry and has been found in waterways downstream of such operations. Due to its relatively stable environmental presence, trenbolone may migrate downstream where it can impact drinking water resources. Trenbolone was exposed to hypochlorite under various reaction conditions to determine its stability and the scope of its transformation by-products. The results indicate trenbolone is highly reactive in the presence of hypochlorite and results in an extensive number of transformation by-products. Continued exposure to hypochlorite resulted in a highly dynamic system involving secondary transformations of most of the initial by-products. The results indicate the reactivity of trenbolone is affected by pH and alters the distribution of observed transformation by-products.

P.aataeda monoterpene emission rates were at least ten times higher than oxygenated monoterpene and sesquiterpene emissions in all seasons. a-pinene and b-pinene were the most abundant emissions, while b-caryophyllene had the highest sesquiterpene emission rate from this species. b-phellandrene was the dominant compound emitted from P. virginiana, followed by the sesquiterpene b-caryophyllene. Sesquiterpene emissions from P. virginiana have not been reported in the literature previously. Summer sesquiterpene emissions from P. virginiana were nearly as high as monoterpene emissions, but were 4-12 times lower than monoterpene emissions in the other seasons. Oxygenated monoterpenes and 2-methyl-3-buten-2-ol were emitted at higher rates from P. taeda than from P. virginiana. Temperature response of the pinenes from P. taeda is similar to previously reported values used in emission models, while that for other compounds falls at the lower end of the previously reported range. Temperature response of all compounds from P. virginiana is in reasonable agreement with previously reported values from other pine species. There is evidence of light dependence of sesquiterpene emission after accounting for temperature response from both species. This effect is somewhat stronger in P. taeda. Bud break, needle expansion, and needle fall (and therefore wind events) seemed to increase monoterpene emission during non-summer seasons. In some instances springtime monoterpene emissions were higher than summertime emissions despite cooler temperatures. Emissions of individual compounds within monoterpene, oxygenated monoterpene, and sesquiterpene classes were highly correlated with each other. Compounds from different classes were much less correlated within each species. This is due to a varying temporal emission patterns for each BVOC class and suggests different production, storage, and emission controls for each. Analysis of enclosure blanks and diurnal patterns indicates that, despite precautions, disturbance due to the enclosure technique may still impact monoterpene emission rate estimates. This did not appear to affect sesquiterpene emissions.

This changes the pre-existing groundwater geochemistry and makes uranium more mobile in solution. Aquifers within the mining zone are often not suitable drinking-water supplies, but surrounding aquifer zones can be of drinking water quality. Local groundwater users are concerned about future impacts on their water quality with nearby ISR mines (either existing or proposed). This research proposes strategies for addressing the following questions at proposed uranium ISR mines: 1) how well do identified aquitards limit groundwater flow between aquifers? 2) what is the groundwater quality at the end of mining after restoration efforts are complete? 3) what is the long-term fate and transport of any groundwater contaminants away from the mined zone? In order to address these questions, a number of steps should be taken to determine how surrounding groundwater quality may or may not be affected by ISR mining. First, understanding the basic hydrogeologic and geochemical system is critical. Second, predictive modeling using reactive transport simulations can be used to simulate future groundwater conditions (during mining and post-restoration). Third, predictive modeling can be used to evaluate how well surrounding groundwater quality is protected under the proposed mine plan design and to evaluate possible design alternatives. Fourth, model shortcomings should be evaluated to provide a reasonable range of prediction uncertainties. The goal of this research is to provide strategies for better understanding the most probable fate and transport of uranium and other constituents during and after uranium ISR operations. This information will assist mining companies, permitting agencies, and local groundwater users in making more informed decisions that maximize protection of groundwater quality.

This aquifer has been impacted by volatile organic compounds from an unidentified source or sources. This paper will describe the hydrogeologic investigation methods applied by U.S. EPA under the Superfund program to characterize ground water contamination at this site and to try to identify the source. To develop the hydrogeologic conceptual model aerial photography, geologic mapping, topographic mapping, surface water mapping, and data on potential contaminant sources were analyzed. Locations for the initial set of six monitoring wells were then chosen based on the conceptual model and the results of a soil sampling program. Because the site is underlain by fractured volcanic rock, a suite of borehole geophysical tools were used to investigate the hydrogeology. Six boreholes were completed to depths up to 325 feet below ground surface. Caliper, natural gamma, acoustic televiewer, optical televiewer, self potential, single-point resistance, formation resistivity, fluid temperature, and fluid conductivity logs were collected in each well. These data were used to select zones for heat pulse flow meter (HPFM) logging. HPFM logs were collected under ambient conditions and then under pumped conditions. The results of the HPFM logging were used to identify intervals for packer testing and sampling. The results of the packer testing, along with the other borehole geophysical data, were used to design a multilevel monitoring well for each location. The Flexible Underground Liner Technology (FLUTe) multilevel well system was chosen for use at the site. After the multilevel monitoring wells were installed, water levels were measured and ground water samples were collected to characterize ground water quality. The results of the geophysical logging, water level monitoring, and groundwater sampling were used to further develop the conceptual model. Using the conceptual model, additional monitoring well locations were selected upgradient of groundwater contamination observed in the bedrock to try to identify sources in the overburden. The results of the well installation and groundwater sampling will be used to update and revise the conceptual model.

The working hypotheses of this study are that 1.) the physical properties of modern varves from Conroy Lake, Monticello, ME reflect variations in measurements from more common laboratory methods (magnetic susceptibility, loss on ignition, RGB analysis, stable isotopes), and 2.) land use changes in the region have altered varve characteristics at Conroy Lake. Previous pollen analyses done on Conroy Lake (Gajewski, 1987) show increases in the Ambrosia and Rumex horizons at approximately 1830, which can be attributed to human settlement and town incorporation of Monticello in 1846. Historical accounts show that the early settlers utilized the land for farming and logging. A surface piston core taken in 2009 from Conroy Lake exhibits increasing trends in magnetic susceptibility ( approximately 1.5 SI to approximately 4 SI) and delta (super 15) N ( approximately 15ppm to approximately 30ppm) at approximately 40cm core depth. These changes are hypothesized to be due to land use change associated with the pollen shifts previously identified. Petrographic thin sections were made from the uppermost 77 cm of the 2009 piston core in order to quantitatively study the varves in light of the anthropogenic change in proxy data observed at approximately 40cm. Preliminary varve counts have been taken from five thin section depths. Mean varve thicknesses below 40 cm downcore are thinner, with Section M (z = 67-67.4 cm) exhibiting a mean thickness of 0.04 cm, and both Section L Upper (z = 62.5-63.4 cm) and Section L Lower (z = 64.4-65.1 cm) exhibiting a mean thickness of 0.05 cm. Above 40 cm, Section F (z = 27.9-30.9 cm) shows a mean thickness of 0.13 cm; Section E (z = 22.7-27.0 cm) a mean thickness of 0.18 cm; and Section D (z = 18.8-21.5 cm) a mean thickness of 0.17 cm. The change in varves show a statistically significant increase in thickness between pre-human appearance (mean = 0.045 cm) and post appearance (mean = 0.162 cm) (t-test t=-11.4; p<<0.0001). Results to date suggest a connection between local environmental change and varve thickness at Conroy Lake. Ongoing analysis of 3 freeze cores, which have preserved the upper flocculent sediments in situ, will help to increase varve resolution and the ability to measure their physical properties.

The purpose of this study is to define seismic stratigraphic units preserved in the Holocene sedimentary package to assist with ongoing lithostratigraphic analyses of sediment cores. Geophysical data were collected using a 200 kHz Humminbird depth sounder and a 10 kHz StrataBox sub-bottom profiler during the summers of 2009-10. The bathymetric survey revealed three basins, the deepest of which is 32.3 m. Sub-bottom data reveal a maximum of 6.7 m of sediment above "basement," which is likely Pleistocene glacial sediment. Five seismic reflectors (A, B, C, D, and E) are observed above acoustic basement at depths of 1.2 mblf, 2.0 mblf, 3.4 mblf, 4.0 mblf, 5.2 mblf, respectively. In order to ground-truth the observed seismic facies, a composite sediment record was constructed from sediment cores taken from the deepest basin of Tea Pond. A multi-proxy approach is being conducted on the cores, including visual core logging, image analysis, loss on ignition, magnetic susceptibility, dry and wet bulk density, OC/N ratios, delta (super 15) N, and delta (super 13) C. Preliminary data suggest common sub-bottom depths between seismic reflectors and changes in lithology and dry bulk density. A change in lithology occurs at 1.22 mblf from a massive brown gyttja to a brown and black laminated gyttja. At the depth in the cores, an increase in dry bulk density is observed from 0.10 g/cm (super 3) to 0.13 g/cm (super 3) . The observed lithofacies change is correlative with seismic reflector A (1.2 mblf). Seismic reflectors B, C, and D occur within the same black laminated gyttja lithofacies, and dry bulk density anomalies occur at these depths. A strong reflector (E) occurs at 5.2 mblf in the sub-bottom data. A change in lithofacies from dark black laminated gyttja to a gray clay unit, as well as an increase in dry bulk density from 0.19 g/cm (super 3) to 0.75 g/cm (super 3) , at a depth of 5.4 mblf appears to correspond with this reflector. Additionally, core refusal occurred at 6.68 mblf, which is consistent with the depth to "basement". Data to date suggest that Tea Pond contains a high resolution record of sedimentation during the Holocene Epoch. Ongoing multiproxy analyses are being utilized to reconstruct environmental change in the region throughout the Holocene.

Standard methods to measure these bacteria take at least 24 hours to obtain results. Molecular approaches such as quantitative polymerase chain reaction (qPCR) can estimate these bacteria faster, in under 3 hours. Previously, we demonstrated that measurements of the fecal indicator bacteria Enterococcus using qPCR were associated with gastrointestinal (GI) illness among swimmers at freshwater beaches. In this paper, we report on results from three marine beach sites. We interviewed beach-goers and collected water samples at marine beaches affected by treated sewage discharges in Mississippi in 2005, and Rhode Island and Alabama in 2007. Ten to twelve days later, we obtained information about gastrointestinal, respiratory, eye, ear and skin symptoms by telephone. We tested water samples for fecal indicator organisms using qPCR and other methods. We enrolled 6,350 beach-goers. The occurrence of GI illness among swimmers was associated with a log10-increase in exposure to qPCR-determined estimates of fecal indicator organisms in the genus Enterococcus (AOR = 2.6, 95% CI 1.3-5.1) and order Bacteroidales (AOR = 1.9, 95% CI 1.3-2.9). Estimates of organisms related to Clostridium perfringens and a subgroup of organisms in the genus Bacteroides were also determined by qPCR in 2007, as was F+ coliphage, but relationships between these indicators and illness were not statistically significant. This study provides the first evidence of a relationship between gastrointestinal illness and estimates of fecal indicator organisms determined by qPCR at marine beaches.

Although studied for many years, there is a surprising lack of information relating tissue levels of carbaryl with ChE activity in the same animals. The present studies were undertaken to describe the dose-response relationship about 40min (approximate time of maximal ChE inhibition) after oral treatment in adult, post-natal day (PND) 17, and PND11 rats. Additionally, the time-course of plasma ChE activity and carbaryl levels in adult rats was determined after a 30mg/kg dosage of carbaryl. The time-course study found that carbaryl levels could be detected in plasma 1h after dosing, but rapidly decreased below the level of quantitation by the 2h time point. In the dose-response studies, treatment-related increases in plasma and brain carbaryl levels were observed 40min after dosing. Plasma levels of carbaryl increased linearly, while brain levels appeared to asymptote after 75mg/kg carbaryl. Plasma and brain levels of carbaryl appeared to be linearly related with a slope close to 1 after various dosages (range: 1-75mg/kg) of carbaryl at the 40min time point. Finally, the dose-related relationship between tissue levels of carbaryl and ChE activity was described using a first order exponential decay function with an asymptote. The parameters of this function did not appear to differ between adult, PND17, or PND11 rats. This indicates that age-related differences in brain ChE inhibition by carbaryl are unlikely to be the result of greater tissue levels of the pesticide in PND11 animals. These are the first studies to report the relationship between brain and plasma tissue levels of carbaryl and ChE activity on an individual animal basis. The results of these experiments will be useful to extend physiologically-based pharmacokinetic models for carbaryl and their application in risk assessment.

PubMed was searched for epidemiologic studies pertinent to the lung and bladder cancer risk estimates from low-dose arsenic exposure. Articles published from 2001, the date of the NRC assessment, through September 2010 were included. Fourteen epidemiologic studies on lung and bladder cancer risk were identified as potentially useful for the analysis. Recent epidemiologic studies that have investigated the risk of lung and bladder cancer from low arsenic exposure are limited in their ability to detect the NRC estimates of excess risk because of sample size and less than lifetime exposure. Although the ecologic nature of the Taiwanese studies on which the NRC estimates are based present certain limitations, the data from these studies have particular strengths in that they describe lung and bladder cancer risks resulting from lifetime exposure in a large population and remain the best data on which to conduct quantitative risk assessment. Continued follow-up of a population in northeastern Taiwan, however, offers the best opportunity to improve the cancer risk assessment for arsenic in drinking water. Future studies of arsenic < 100 mu g/L in drinking water and lung and bladder cancer should consider adequacy of the sample size, the synergistic relationship of arsenic and smoking, duration of arsenic exposure, age when exposure began and ended, and histologic subtype.

AN - 756659517; 20691712 AB - The Salmonella mutagenicity assay can be performed using cells that are in different growth phases. Thus, the plate-incorporation assay involves plating stationary-phase cells with the mutagen, after which the cells undergo a brief lag phase and, consequently, are exposed to the mutagen and undergo mutagenesis while in the logarithmic (log) phase. In contrast, a liquid-suspension assay involves exposure of either log- or stationary-phase cells to the mutagen for a specified period of time, sometimes followed by a wash, resulting in the cells growing in medium in the absence of the mutagen. To explore global gene expression in Salmonella, and to test for possible effects of growth phase and transcriptional status on mutagenesis, we performed microarray analysis on cells of Salmonella strain TA100 exposed to the drinking-water mutagen MX in either the log or stationary phase. The genes in functional pathways involving amino acid transport and metabolism and energy metabolism were expressed differentially in log-phase cells, whereas genes in functional pathways involving protein trafficking, cell envelope, and two-component systems using common signal transduction were expressed differentially in stationary-phase cells. More than 90% of the ribosomal-protein biosynthesis genes were up-regulated in stationary- versus log-phase cells. MX was equally mutagenic to cells in log- and stationary-phase growth when the results were expressed as mutant frequencies (revertants/survivors/μM), but it was twice as mutagenic in stationary-phase cells when the results were expressed as mutant yields (revertants/nmole or revertants/μM). There was a complex transcriptional response underlying these results, with mucA/B being greatly up-regulated in log-phase cells but umuC/D up-regulated in stationary-phase cells.

We compared the ability of the fungal Penicillium chrysogenum (PCE) and house dust mite (HDM) extracts to induce allergic responses in BALB-c mice. The extracts were administered by intratracheal aspiration (IA) at several doses (0, 2.5, 5, 10, 20, 40, and 80 kg) four times over a 4-week period. Three days after the last IA exposure, serum and bronchoalveolar lavage fluid (BALF) were collected. The relative allergenicity of the extracts was evaluated based on the lowest dose able to induce a significant response compared to control (0 kg) and the robustness of the response. PCE induced the most robust response at the lowest dose for most endpoints examined: BALF total, macrophage, neutrophil, and eosinophil cell counts, and antigen-specific IgE. Taken together, our data suggest that PCE may induce a more robust allergic and inflammatory response at lower doses than HDM.Practical ImplicationsOur data suggest that Penicillium chrysogenum is a robust allergen and may be a more potent allergen source than house dust mite (HDM) in this mouse model. Two critical factors in the development of human allergic disease, exposure levels and sensitization thresholds, are unknown for most allergens including molds-fungi. Human exposure levels are not within the scope of this article. However, the data presented suggest a threshold dose for the induction of allergic responsiveness to P. chrysogenum. Additionally, P. chrysogenum as well as other molds may play an important role in asthma development in our society.

It is an improvement over previous models like the Vinegar and Waxman model, which do not account explicitly for the effect of frequency. The Vinegar and Waxman model can be considered as a limiting case of the Revil and Florsch model in the limit where the distribution of relaxation times is very broad. The extended model is applied to the case of unconsolidated sands partially saturated with oil and water. Laboratory experiments were performed to investigate the influence of oil saturation, frequency, grain size, and conductivity of the pore water upon the complex resistivity response of oil-bearing sands. The low-frequency polarization (below 100 Hz) is dominated by the polarization of the Stern layer (the inner part of the electrical double layer coating the surface of the grains in contact with water). The phase exhibits a well-defined relaxation peak with a peak frequency that is dependent on the mean grain diameter as predicted by the model. Both the resistivity and the magnitude of the phase increase with the relative saturation of the oil. The imaginary (quadrature) component of the complex conductivity is observed to decrease with the oil saturation. All these observations are reproduced by the new model.

The levels of organochlorine pesticides measured in this study were generally low. The highest concentration of OCPs was measured for dichlorodiphenyltrichloroethane compounds (DDTs) (p,pa super(2)-DDT, o,pa super(2)-DDT, p,pa super(2)-DDE, o,pa super(2)-DDE, p,pa super(2)-DDD and o,pa super(2)-DDD), followed by chlordane compounds (CHLs) (trans-chlordane, cis-chlordane, trans-nonachlor and cis-nonachlor), hexachlorobenzene (HCB) and gamma-hexachlorocyclohexane ( gamma -HCH). The relatively high ratio of p,pa super(2)-DDT/p,pa super(2)-DDE in tilapia and catfish with an extremely high value in catfish purchased from a local market at Madina, a suburb of Accra, however, suggests the fresh contamination of technical DDT in Ghana. Although PCDD/Fs and dl-PCBs showed relatively low levels, the concentrations are, however, comparable with recent data of some developed countries. There is a potential health risk from DDTs, PCDD/Fs and dl-PCBs for the general population of Ghana because fish is one of their important protein sources. It is therefore necessary to estimate the total intake of DDTs, PCDD/Fs and dl-PCBs, and to assess the health risks for the general population of Ghana.

Primary cultures of neurons have been widely utilized to study the actions of pyrethroids, yet pyrethroid accumulation in these cells has not been studied to date. To test the hypothesis that pyrethroids rapidly accumulate in neurons in vitro, the time (0-90min) and concentration (0.05-10 mu M) dependent accumulation of [3H]-deltamethrin (DM), [3H]-bifenthrin (BF) and [14C]-cis permethrin (PM) into primary cortical cultures was examined. Accumulation of all three pyrethroids was time- and concentration-dependent, with only small differences observed between the compounds. Concentration-dependent accumulation of PM and BF were similar, achieving a of total ~0.25 nmol in cells after 30min in a 10 mu M solution. DM accumulation was lower, reaching a maximum of 0.14 nmol after 30min in a 10 mu M solution. In 1 mu M solutions, DM and PM content in cells were 0.039 and 0.038 nmol after 90min. At all concentrations and times, pyrethroid accumulation in cells was less than 5% of the total mass applied for DM and PM, and was less than 8% for BF. However, after 90min, accumulation of all three compounds increased to as much as ~30-50-fold higher than the surrounding medium. The amount of compound recovered in the media at the end of incubation ranged from ~77% to 89%; the remainder (6-15%) was presumed to bind to the plastic of the culture plates. These results demonstrate rapid time- and concentration-dependent accumulation of pyrethroids in neurons in vitro. Further, for the three pyrethroids examined, there were not statistically significant differences in their accumulation. This data will be useful for making comparisons between in vivo and in vitro studies regarding effective concentrations of pyrethroids.

In this study, sequences from the V2 region of the small subunit ribosomal RNA gene were targeted in the development of qPCR assays to quantify DNA from six Bacteroides and one Prevotella species. In silico and experimental analyses suggested that each of the assays was highly discriminatory in detecting DNA from the intended species. Analytical sensitivity, precision and ranges of quantification were demonstrated for each assay by coefficients of variation of less than 2% for cycle threshold measurements over a range from 10 to 4A-104 target sequence copies. The assays were applied to assess the occurrence and relative abundance of their target sequences in feces from humans and five animal groups as well as in 14 sewage samples from 13 different treatment facilities. Sequences from each of the species were detected at high levels (>103 copies/ng total extracted DNA) in human wastes. Sequences were also detected by each assay in all sewage samples and, with exception of the Prevotella sequences, showed highly correlated (R 2 a[control][yen0.7) variations in concentrations between samples. In contrast, the occurrence and relative abundance profiles of these sequences differed substantially in the fecal samples from each of the animal groups. These results suggest that analyses for multiple individual Bacteroidales species may be useful in identifying human fecal pollution in environmental waters.

Between April and July 2006, we collected reproductive histories, questionnaires, and blood samples from 102 women, aged 16-45years, who delivered at a Memphis, TN hospital. The prevalence of preeclampsia and low birth weight infancy in the study population was 11% and 10%, respectively. Twenty-eight percent of mothers reported living near a potential Pb-contaminated area, while 43% lived in a residence built before 1978. Geometric mean (GM) concentrations for umbilical cord blood in the study population were 1.3, 3.5, 9.0, and 52.0 mu g/dL for Pb, Mn, Cr, and Cu, respectively. Six neonates had cord blood Pb (CBL) concentrations above 10 mu g/dL, while 20 had CBL concentrations greater than or equal to 2 mu g/dL. GM umbilical CBL levels were higher in neonates born to women living near a potential Pb-contaminated area (2.2 vs. 1.1 mu g/dL) and those with friends, family or household members exposed to lead products (1.6 vs. 1.1 mu g/dL). Some evidence of an exposure-response relationship was also detected between all four metal concentrations and an increasing number of maternal lead exposures. After adjustment for confounding, proximity to a Pb-contaminated area was the strongest environmental determinant of CBL levels among neonates with CBL concentrations of greater than or equal to 2 mu g/dL (odds ratio=5.1; 95% CI=1.6, 16.7). Metal concentrations were elevated in this population, and CBL levels were associated with proximity to Pb-contaminated areas.

Environmental risk factors, particularly those related to housing and indoor air, may impact the development or exacerbation of asthma. There is increasing evidence to suggest a link between obesity-related health problems and asthma. Previous studies have also reported that immigrant status may influence myriad risk factors and health outcomes among immigrant populations. The Arab American Environmental Health Project (AAEHP) was the first study to explore environmental health problems among Arab Americans. This paper examined whether hypertensive status modified the relationship between environmental risk factors and asthma among Arab Americans in metro Detroit. An environmental risk index (ERI) was used to quantify household environmental risk factors associated with asthma. Physician diagnosed hypertension was self-reported, and asthma status was determined using responses to a validated symptoms checklist and self-reported diagnosis by a physician. Hypertension significantly modified the relationship between ERI and asthma in this study population. The positive association between household environmental risk factors and asthma was stronger among participants diagnosed with hypertension. Effect modification of the relationship between environmental risk factors and asthma could have serious implications among high-risk communities. However, further research is needed to elucidate the relationships between hypertension, environmental risk factors, and asthma. Adapted from the source document.

AN - 756308565; 20496936 AB - The U.S. Environmental Protection Agency's "Four Lab Study" involved participation of researchers from four national Laboratories and Centers of the Office of Research and Development along with collaborators from the water industry and academia. The study evaluated toxicological effects of complex disinfection byproduct (DBP) mixtures, with an emphasis on reproductive and developmental effects that have been associated with DBP exposures in some human epidemiologic studies. This paper describes a new procedure for producing chlorinated drinking water concentrate for animal toxicology experiments, comprehensive identification of >100 DBPs, and quantification of 75 priority and regulated DBPs. In the research reported herein, complex mixtures of DBPs were produced by concentrating a natural source water with reverse osmosis membranes, followed by addition of bromide and treatment with chlorine. By concentrating natural organic matter in the source water first and disinfecting with chlorine afterward, DBPs (including volatiles and semivolatiles) were formed and maintained in a water matrix suitable for animal studies. DBP levels in the chlorinated concentrate compared well to those from EPA's Information Collection Rule (ICR) and a nationwide study of priority unregulated DBPs when normalized by total organic carbon (TOC). DBPs were relatively stable over the course of the animal studies (125 days) with multiple chlorination events (every 5-14 days), and a significant portion of total organic halogen was accounted for through a comprehensive identification approach. DBPs quantified included regulated DBPs, priority unregulated DBPs, and additional DBPs targeted by the ICR. Many DBPs are reported for the first time, including previously undetected and unreported haloacids and haloamides. The new concentration procedure not only produced a concentrated drinking water suitable for animal experiments, but also provided a greater TOC concentration factor (136×), enhancing the detection of trace DBPs that are often below detection using conventional approaches.

AN - 755970069; 20795664 AB - Ecological risks to aquatic organisms are typically assessed using acute toxicity data for relatively few species and with limited understanding of relative species sensitivity. We developed a comprehensive set of interspecies correlation estimation (ICE) models based on acute toxicity data for aquatic organisms and evaluated three key sources of model uncertainty: taxonomic relatedness, chemical mode of action (MOA), and model parameters. Models are least-squares regressions of acute toxicity of surrogate and predicted species. A total of 780 models were derived from acute values for 77 species of aquatic organisms and over 550 chemicals. Cross-validation of models showed that accurate model prediction was greatest for models with surrogate and predicted taxa within the same family (91% of predictions within 5-fold of measured values). Recursive partitioning provided user guidance for selection of robust models using model mean square error and taxonomic relatedness. Models built with a single MOA were more robust than models built using toxicity values with multiple MOAs, and improve predictions among species pairs with large taxonomic distance (e.g., within phylum). These results indicate that between-species toxicity extrapolation can be improved using MOA-based models for less related taxa pairs and for those specific MOAs.

AN - 755190498; 20660472 AB - Conversion of arsenate to arsenite is a critical event in the pathway that leads from inorganic arsenic to a variety of methylated metabolites. The formation of methylated metabolites influences distribution and retention of arsenic and affects the reactivity and toxicity of these intermediates. Indeed, some of the toxic and carcinogenic effects associated with exposure to arsenate or arsenite are probably mediated by methylated arsenicals. Recent work has demonstrated a biologically plausible role for phosphorolytic-arsenolytic enzymes in a reaction scheme in which an "activated" arsenate ester is readily reduced by thiols to arsenite. Thiol-dependent reduction of arsenate esters formed by arsenolysis may be one of several functionally reductant processes that control the flux of arsenic into the cellular pathway for arsenic methylation. Integrating these reductive processes into a conceptual model for arsenic metabolism may provide new insights into the cellular machinery for handling this toxic metalloid.

AN - 755190495; 20639261 AB - Many chemicals in commerce today have undergone limited or no safety testing. To reduce the number of untested chemicals and prioritize limited testing resources, several governmental programs are using high-throughput in vitro screens for assessing chemical effects across multiple cellular pathways. In this study, metabolic clearance and plasma protein binding were experimentally measured for 35 ToxCast phase I chemicals. The experimental data were used to parameterize a population-based in vitro-to-in vivo extrapolation model for estimating the human oral equivalent dose necessary to produce a steady-state in vivo concentration equivalent to in vitro AC(50) (concentration at 50% of maximum activity) and LEC (lowest effective concentration) values from the ToxCast data. For 23 of the 35 chemicals, the range of oral equivalent doses for up to 398 ToxCast assays was compared with chronic aggregate human oral exposure estimates in order to assess whether significant in vitro bioactivity occurred within the range of maximum expected human oral exposure. Only 2 of the 35 chemicals, triclosan and pyrithiobac-sodium, had overlapping oral equivalent doses and estimated human oral exposures. Ranking by the potencies of the AC(50) and LEC values, these two chemicals would not have been at the top of a prioritization list. Integrating both dosimetry and human exposure information with the high-throughput toxicity screening efforts provides a better basis for making informed decisions on chemical testing priorities and regulatory attention. Importantly, these tools are necessary to move beyond hazard rankings to estimates of possible in vivo responses based on in vitro screens.

AN - 755190259; 20562218 AB - Hexabromocyclododecane-gamma (γ-HBCD) is the predominate diastereoisomer in the commercial HBCD mixture used as a flame retardant in a wide variety of consumer products. Three main diastereoisomers, alpha (α), beta (β), and gamma (γ), comprise the mixture. Despite the γ-diastereoisomer being the major diastereoisomer in the mixture and environmental samples, the α-diastereoisomer predominates human tissue and wildlife. This study was conducted to characterize absorption, distribution, metabolism, and excretion parameters of γ-HBCD with respect to dose and time following a single acute exposure and repeated exposure in adult female C57BL/6 mice. Results suggest that 85% of the administered dose (3 mg/kg) was absorbed after po exposure. Disposition was dose independent and did not significantly change after 10 days of exposure. Liver was the major depot (< 0.3% of dose) 4 days after treatment followed by blood, fat, and then brain. γ-HBCD was rapidly metabolized and eliminated in the urine and feces. For the first time, in vivo stereoisomerization was observed of the γ-diastereoisomer to the β-diastereoisomer in liver and brain tissues and to the α- and β-diastereoisomer in fat and feces. Polar metabolites in the blood and urine were a major factor in determining the initial whole-body half-life (1 day) after a single po exposure. Elimination, both whole-body and from individual tissues, was biphasic. Initial half-lives were approximately 1 day, whereas terminal half-lives were up to 4 days, suggesting limited potential for γ-diastereoisomer bioaccumulation. The toxicokinetic behavior reported here has important implications for the extrapolation of toxicological studies of the commercial HBCD mixture to the assessment of risk.

AN - 755170128; 20655892 AB - Carbon monoxide (CO) in tissues and cells can originate from inhalation of CO or endogenously. Endogenous production, carboxyhemoglobin (COHb) formation, and exhaled CO levels are influenced by physiological factors, including disease. It is suggested that endogenous CO production can be used as a biomarker for oxidative and inflammatory processes. Also, endogenous CO can contribute to increased body burden of CO, which may both disrupt normal CO signaling cascades and increase the risk of CO toxicity. Published by Elsevier Inc.

All of the spatially explicit fully distributed hydraulic and hydrological models use topography (represented by the DEM of the area modelled) to derive bathymetry. DEM is also used to derive some other key information critical in fully distributed hydraulic and hydrological models. With high-resolution DEMs such as LiDAR (Light Detection and Ranging) becoming more readily available and also with the advancements in computing facilities which can handle these large data sets, there is a need to quantify the impact of using different resolution DEMs (e.g. 1m against 10m or 25m) on hydrologically important variables and the loss of accuracy and reliability of the results as we move from high resolution to coarser resolution. The results from statistical analysis carried out to compare field survey elevations with the LiDAR DEM-derived elevations, show that there are small differences between the two data sets but LiDAR DEM is a reasonably good representation of the actual ground surface compared to other commonly used DEMs derived from contour maps. The results from the analysis clearly show that the accuracy and resolution of the input DEM have serious implications on the values of the hydrologically important spatial indices derived from the DEM. The result also indicates that the loss of details by re-sampling the higher resolution DEM to coarser resolution are much less compared to the details captured in the commonly available coarse resolution DEM derived from contour maps. Topographic indices based on contour derived DEMs should be used with caution and where available, the higher resolution DEM should be used instead of the coarse resolution one.

Diet selection of urban breeding Desert Eagle Owls (Bubo ascalaphus) in Hurghada, Egypt AN - 1777103850; 13248300 AB - The diet selection of Desert Eagle Owl (Bubo ascalaphus) was investigated in the outskirts of Hurghada, the Egyptian Western Desert, and the results were used to test the main hypotheses describing the urbanization process of these birds. The diet primarily comprised mammals (78%) and birds (11.3%), with a small proportion of arthropods (9.2%) and reptiles (2.1%). The diet had a low diversity and was dominated by the two mammal species and a temporally abundant migrant bird species. The mammalian component of the diet is the most important in terms of biomass (91.7%), with the Norway Rat (Rattus norvegicus) dominating both by number (66.1%) and by biomass (89.1%). The results suggest that in the urban environments of Hurghada the Desert Eagle Owl is an opportunistic feeder, relying on exotic mammals. The major driving effect for its new habitat choice is the abundance of the main prey.

Surficial sediment was collected in 2003 from 29 sites along five streams with watersheds that extend from the core of the metropolitan area to its development fringe. Sediment was analyzed for 16 polycyclic aromatic hydrocarbons (PAHs), 3 common polychlorinated biphenyl mixtures (Aroclors), and 25 pesticide-related compounds of eight chemical classes. Multiple PAHs were detected at more than 50% of the sites, and concentrations of total PAHs ranged from 290 to 82,150 mu g/kg (dry weight). The concentration and frequency of detection of PAHs increased with increasing urbanization of the residential watersheds. Four- and five-ring PAH compounds predominated the PAH composition (73-100%), especially fluoranthene and pyrene. The PAH composition profiles along with the diagnostic isomer ratios [e.g., anthracene/(anthracene + phenanthrene), 0.16 + or - 0.03; fluoranthene/(fluoranthene + pyrene), 0.55 + or - 0.01)] indicate that pyrogenic sources (i.e., coal-tar-related operations or materials and traffic-related particles) may be common PAH contributors to these residential streams. Historical-use organochlorine insecticides and their degradates dominated the occurrences of pesticide-related compounds, with chlordane and dieldrin detected in over or nearly 50% of the samples. The occurrence of these historical organic compounds was associated with past urban applications, which may continue to be nonpoint sources replenishing local streams. Concentrations of low molecular weight (LMW; two or three rings) and high molecular weight (HMW; four to six rings) PAHs covaried along individual streams but showed dissimilar distribution patterns between the streams, while the historical pesticide-related compounds generally increased in concentration downstream. Correlations were noted between LMW and HMW PAHs for most of the streams and between historical-use organochlorine compounds and total organic carbon and clay content of sediments for one of the streams (Brush Creek). Stormwater runoff transport modes are proposed to describe how the two groups of contaminants migrated and distributed in the streambed.

Physical, chemical, and toxicity data (Hyalella azteca 28-day whole-sediment toxicity test) for 29 samples collected in 2003 were used for this evaluation, and the potential causes for the toxic effects were explored. The sediments exhibited a low to moderate toxicity, with five samples identified as toxic to H. azteca. Metals did not likely cause the toxicity based on low concentrations of metals in the pore water and elevated concentrations of acid volatile sulfide in the sediments. Although individual polycyclic aromatic hydrocarbons (PAHs) frequently exceeded effect-based sediment quality guidelines [probable effect concentrations (PECs)], only four of the samples had a PEC quotient (PEC-Q) for total PAHs over 1.0 and only one of these four samples was identified as toxic. For the mean PEC-Q for organochlorine compounds (chlordane, dieldrin, sum DDEs), 4 of the 12 samples with a mean PEC-Q above 1.0 were toxic and 4 of the 8 samples with a mean PEC-Q above 3.0 were toxic. Additionally, four of eight samples were toxic, with a mean PEC-Q above 1.0 based on metals, PAHs, polychlorinated biphenyls (PCBs), and organochlorine pesticides. The increase in the incidence of toxicity with the increase in the mean PEC-Q based on organochlorine pesticides or based on metals, PAHs, PCBs, and organochlorine pesticides suggests that organochlorine pesticides might have contributed to the observed toxicity and that the use of a mean PEC-Q, rather than PEC-Qs for individual compounds, might be more informative in predicting toxic effects. Our study shows that stream sediments subject to predominant nonpoint sources contamination can be toxic and that many factors, including analysis of a full suite of PAHs and pesticides of both past and present urban applications and the origins of these organic compounds, are important to identify the causes of toxicity.

Results of animal studies have varied depending on species, strain, and treatment. METHODS: We compared birth weight and adult health in offspring following 50% maternal undernutrition on gestation days (GD) 1-15 (UN1-15) or GD 10-21 (UN10-21) in Sprague Dawley and Wistar rats. Offspring from food-deprived dams were weighed and cross-fostered to control dams. Litters were weighed during lactation and initiating at weaning males were fed either control or a high-fat diet. Young and mature adult offspring were evaluated for obesity, blood pressure (BP), insulin response to oral glucose, and serum lipids. Nephron endowment, renal glucocorticoid receptor, and renin-aldosterone-angiotensin system components were measured. RESULTS: The UN10-21 groups had birth weights lower than controls and transient catch up growth by weaning. Neither strain demonstrated obesity or dyslipidemia following prenatal undernutrition, but long-term body weight deficits occurred in the UN groups of both strains. High-fat diet fed offspring gained more weight than control offspring without an effect of prenatal nutrition. Sprague Dawley were slightly more susceptible than Wistar rats to altered insulin response and increased BP following gestational undernutrition. Nephron endowment in Sprague Dawley but not Wistar offspring was lower in the UN10-21 groups. Glucocorticoid and renin-aldosterone-angiotensin system pathways were not altered. CONCLUSIONS: The most consistent effect of maternal undernutrition was elevated BP in offspring.

This paper describes the application of a previously verified watershed loading model to estimate total nitrogen loading rates and relative source contributions to 74 small-medium sized embayment-type estuaries in southern New England. The study estuaries exhibited a gradient in nitrogen inputs of a factor of over 7000. On an areal basis, the range represented a gradient of approximately a factor of 140. Therefore, all other factors being equal, the study design is sufficient to evaluate ecological effects conceptually tied to excess nitrogen along a nitrogen gradient. In addition to providing total loading inputs rates to the study estuaries, the model provides an estimate of the relative contribution of the nitrogen sources from each watershed to each associated estuary. Cumulative results of this analysis reveal the following source ranking (means): direct atmospheric deposition (37%), wastewater (36%), >indirect atmospheric deposition (16%)>fertilizer (12%). However, for any particular estuary the relative magnitudes of these source types vary dramatically. Together with scientific evidence on symptoms of eutrophication, the results of this paper can be used to develop empirical pressure-state models to determine critical nitrogen loading limits for the protection of estuarine water quality.

We recently published maximum likely exposure rates for several hundred human prescription pharmaceuticals commonly used in the US. These rates were estimated from nationally aggregated marketing data and wastewater production rates. The accuracy of these estimates is unclear, and it is unclear how to use the national-level estimates of exposure to predict local exposure rates. In this study we compare our previous predicted environmental concentrations (PECs), which were based on marketing data, with PECs based on regulatory data. We then use local dispensing rates for 12 APIs along with local wastewater production rates to estimate the distribution of local PECs relative to national averages, in order to identify an a~application factor' suitable for converting national-level PECs into reliable bounds for local concentrations. We compare the national-level PECs and the proposed application factor with measured environmental concentrations (MECs) published in 62 recent peer-reviewed publications. Regulatory data-based national average PECs are uniformly lower than marketing data-based national average PECs, corroborating the intended conservative nature of the marketing data-based PECs. Variability in local API usage and wastewater production rates suggest local PECs may occasionally exceed national averages by about 10-fold. Multiplying national average PECs by an a~application factor' of 10 and comparing the resulting predicted maximum local PECs to published MEC data for 83 APIs corroborates the usefulness of 10-fold adjusted national PECs as a reasonable ceiling for measured environmental concentrations.

Phase I of ToxCast used a battery of 467 in vitro, high-throughput screening assays to assess 309 environmental chemicals. One important mode of action leading to toxicity is endocrine disruption, and the U.S. EPA's Endocrine Disruptor Screening Program (EDSP) has been charged with screening pesticide chemicals and environmental contaminants for their potential to affect the endocrine systems of humans and wildlife. The goal of this study was to develop a flexible method to facilitate the rational prioritization of chemicals for further evaluation and demonstrate its application as a candidate decision-support tool for EDSP. Focusing on estrogen, androgen, and thyroid pathways, we defined putative endocrine profiles and derived a relative rank or score for the entire ToxCast library of 309 unique chemicals. Effects on other nuclear receptors and xenobiotic metabolizing enzymes were also considered, as were pertinent chemical descriptors and pathways relevant to endocrine-mediated signaling. Combining multiple data sources into an overall, weight-of-evidence Toxicological Priority Index (ToxPi) score for prioritizing further chemical testing resulted in more robust conclusions than any single data source taken alone. Incorporating data from in vitro assays, chemical descriptors, and biological pathways in this prioritization schema provided a flexible, comprehensive visualization and ranking of each chemical's potential endocrine activity. Importantly, ToxPi profiles provide a transparent visualization of the relative contribution of all information sources to an overall priority ranking. The method developed here is readily adaptable to diverse chemical prioritization tasks.

Previous studies have identified associations between the proportion of urinary MMA (%MMA) and increased risks of several arsenic-related diseases, although none of these reported on lung cancer. In this study, urinary arsenic metabolites were assessed in 45 lung cancer cases and 75 controls from arsenic-exposed areas in Cordoba, Argentina. Folate has also been linked to arsenic-disease susceptibility, thus an exploratory assessment of associations between single nucleotide polymorphisms in folate metabolizing genes, arsenic methylation, and lung cancer was also conducted. In analyses limited to subjects with metabolite concentrations above detection limits, the mean %MMA was higher in cases than in controls (17.5% versus 14.3%, p =0.01). The lung cancer odds ratio for subjects with %MMA in the upper tertile compared to those in the lowest tertile was 3.09 (95% CI, 1.08-8.81). Although the study size was too small for a definitive conclusion, there was an indication that lung cancer risks might be highest in those with a high %MMA who also carried cystathionine b-synthase (CBS) rs234709 and rs4920037 variant alleles. This study is the first to report an association between individual differences in arsenic metabolism and lung cancer, a leading cause of arsenic-related mortality. These results add to the increasing body of evidence that variation in arsenic metabolism plays an important role in arsenic-disease susceptibility.

Based on about 400 paired samples, we examined the responsiveness of benthic assemblages sampled in the littoral zone and assemblages sampled from the surface of woody snags in the main channel. The assemblages in the two mesohabitats were different in all rivers. Taxa richness was much higher in the benthos than on snags. Macroinvertebrate assemblage response to water quality variation was weak on the Mississippi River, but the reasons for this are unknown. Based on analysis of the similarity between the composition of assemblages from groups of sites with high and low concentrations of water quality variables, benthic assemblages were only slightly more sensitive to water chemistry variation than were snag assemblages. Results of two-sample comparisons between groups of sites with high and low concentrations of water quality variables were consistent with rank correlations of assemblage metrics with water quality. In general, there was little difference between habitats in response to variation in water quality on any river. Our simple method of snag sampling in great rivers is usually much easier than littoral benthic sampling because it does not require wading. Snag sampling in large rivers has some limitations (e.g., natural snags are sometimes absent, samples are semi-quantitative), but lack of sensitivity to water quality gradients compared to the benthos is not among them.

The goal of this research was to identify estuarine benthic invertebrates that could be used as indicator species to detect presence or absence of pollution in the Virginian Biogeographic Province using available monitoring data from the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program. The data were first subdivided by habitat. Then we summarized the benthic community using principal coordinates analysis and projected the results onto a pollution gradient. Then we compared medians and corrected interquartile ranges to identify indicator species that were sensitive to pollution (or lack thereof) and showed low variation in response. Our data set was divided into smaller subsets that ranged from 108 to 532 stations per habitat. Out of 707 species in the Virginian Province, 67 were identified as pollution indicator species; 37 pollution sensitive taxa and 30 pollution tolerant taxa. The pollution sensitive taxa were represented by more phyla than were the pollution tolerant taxa. The pollution tolerant taxa were dominated by deposit feeders while the pollution sensitive taxa were not dominated by animals using any one feeding strategy. The pollution sensitive taxa included many crustaceans, known to be sensitive to pollution, while the pollution tolerant taxa included many tubificid oligochaetes, which are common indicators of pollution. Our empirically based results corresponded well with other studies that identified tolerance values or indicator species. One advantage of this technique is that it can be used on smaller data sets, assuming that there are not major habitat differences among the samples. We believe that this parsimonious technique can be applied to other coastal areas where mid-size (100-500 stations) monitoring data sets are available.

Weibull distributions best fit the observed data from studies with no statistical differences, and are presented by study, age group, and location. As age increases, both indoor and outdoor object-to-mouth frequencies decrease. Object-to-mouth frequency is significantly greater indoors (2-32 contacts/h) than outdoors (average 1-9 contacts/h). This paper compares results to a similar hand-to-mouth frequency meta-analysis. Children who tend to mouth hands indoors also tend to mouth hands outdoors; children who tend to mouth objects indoors tend to mouth objects outdoors. However, children who tend to mouth objects do not necessarily have a tendency to mouth hands. Unlike for hand-to-mouth frequency, a statistical difference was found among the various studies for object-to-mouth frequency. This could be due to different definitions for object mouthing across the studies considered. The analysis highlights the need for additional object-to-mouth data (indoors and especially outdoors) for various age groups using standardized collection and analysis.

To investigate this phenomenon, we examined delta super(13)C values of filter-feeding hard clams Mercenaria mercenaria from 13 locations in Greenwich Bay, a sub-estuary of Narragansett Bay, Rhode Island (USA). The delta super(13)C values of the clams showed a marked linear gradient of 2ppt over the 4 km length of Greenwich Bay (-19 to -17ppt), from lower delta super(13)C values in the inner bay to higher values at the mouth, where Greenwich Bay joins Narragansett Bay proper (R super(2) = 0.94, p < 0.0001). This is in contrast to previous work that has shown that delta super(13)C values of clams in Narragansett Bay proper (over 40 km long) are homogenous (mean +/- SD, -16.8 +/- 0.6 ppt, n = 247). Mean daily pH, temperature, and salinity data from 2 fixed monitoring stations were used to estimate aqueous CO sub(2) (CO sub(2(aq))) concentrations in the surrounding water. CO sub(2(aq)) concentrations were higher in inner Greenwich Bay than immediately outside of the bay, suggesting that the dissolved inorganic carbon sources supporting phytoplankton production are quite different across the bay. The outer Greenwich Bay clams appear to feed on Narragansett Bay phytoplankton with higher delta super(13)C values that are grown in a higher pH, more bicarbonate-rich environment. In contrast, the inner Greenwich Bay clams may feed on phytoplankton grown in lower pH water with a greater availability of CO sub(2(aq)). The lower delta super(13)C of CO sub(2(aq)) relative to HCO sub(3) super(-) is reflected in the phytoplankton and in the clams that feed on them. Our work suggests that delta super(13)C values may be sensitive to changes in inorganic C in estuarine systems, which may confound attempts to use stable isotopes to identify organic carbon sources.

The hypothesis tested was that lowland riverine bacterioplankton are DOC limited when flow events are absent and simulating an increase in assimilable DOC similar to that expected during an environmental flow will lead to heterotrophic dominance. Experiments took place in the Namoi River, a highly regulated lowland river in Australia. Specifically, in situ microcosms were used to examine the responses of bacterioplankton and phytoplankton to various additions of DOC as glucose or leaf leachate, with and without additions of inorganic nutrients. The results indicated that ambient DOC availability limited the bacterioplankton for the three seasons over which we conducted the experiments. When DOC was added alone, dissolved oxygen concentrations decreased primarily because of increased bacterial respiration and bacterioplankton growth generally increased relative to controls. Additions of DOC alone led to a pattern of decreased chlorophyll a concentration relative to controls, except for willow leachate. Additions of inorganic nutrients alone increased chlorophyll a concentrations above controls, indicating limitation of phytoplankton. These findings support our hypothesis. Based on the present results, environmental flows should increase the duration of allochthonously driven heterotrophic dominance, thus shifting regulated lowland rivers to more natural (pre-regulation) conditions for greater periods.

The present study reports the results of a 42-week exposure of estuarine sheepshead minnows (Cyprinodon variegatus) to the androgen, 17 beta -trenbolone (Tb) conducted to determine if partial-(F0) or single-generation (F1) fish exposures identify multigenerational (F0-F3) effects of androgens on fish. Adult F0 fish were exposed to 0.007, 0.027, 0.13, 0.87,and 4.1 mu g Tb/L, the F1 generation to <0.87 mu g Tb/L, the F2 fish to <0.13 mu g Tb/L, and the F3 fish to <0.027 mu g Tb/L. The highest concentrations with reproducing populations at the end of the F0, F1, and F2 generations were 4.1, 0.87, and 0.027 mu g Tb/L, respectively. Reproduction in the F0, F1, and F2 generations was significantly reduced at 0.87, 0.027, and 0.027 mu g Tb/L, respectively. Fish were significantly masculinized in the F1 generation exposed to 0.13 mu g Tb/L or greater. Female plasma vitellogenin was significantly reduced in F0 fish exposed to greater than or equal to 0.87 mu g Tb/L. Gonadosomatic indices of the F0 and F1 generations were significantly increased at 0.87 and 0.13 mu g Tb/L in the F0 and F1 generation, respectively, and were accompanied by ovarian histological changes. Reproduction was the most consistently sensitive measure of androgen effects and, after a life-cycle exposure, the daily reproductive rate predicted concentrations affecting successive generations. The present study provides evidence that a multiple generation exposure of fish to some endocrine-disrupting chemicals can result in developmental and reproductive changes that have a much greater impact on the success of a species than was indicated from shorter term exposures.

In this study, acute and chronic tests were conducted to determine the toxicity and bioconcentration of nonylphenol to freshwater organisms for use in deriving national water quality criteria. Acute median effect concentrations (EC50s) based on loss of equilibrium, immobility, and lethality for species representing several taxonomic groups ranged from 21 to 596 mu g/L. The EC50s were up to a factor of 2 less than median lethal concentrations (LC50s) and decreased with time over the test periods of 24 to 96 h. In chronic tests, early life stages of rainbow trout were 14 times more sensitive to nonylphenol than in acute tests and approximately 20 times more sensitive than Daphnia magna exposed over their complete life cycle. Comparisons of chronic test endpoints showed that 20% effect concentrations (EC20s), determined by regression testing, and chronic values, determined by hypothesis testing, were similar for both the rainbow trout and Daphnia magna. The lowest mean tissue-effect concentrations of nonylphenol appeared to be greater for the fathead minnow than bluegill, and ranged from approximately 130 to 160 mu g/g after 96-h exposure and from approximately 20 to 90 mu g/g after 28-d exposure. Mean lipid normalized bioconcentration factors (BCFs) associated with no-effect concentrations were approximately 180 and 50 for the fathead minnow and bluegill, respectively. The present test results suggest that long-term exposures to nonylphenol at concentrations found in some surface waters could adversely impact sensitive components of freshwater communities.

Individual stands can differ in C content and storage, based on characteristics such as vegetation type, site history, and soil properties. These site differences may cause stands to vary in their response to extreme weather events such as droughts. We examined ecosystem C pools, soil respiration, and litterfall in four hardwood stands with widely varying soil drainage in Rhode Island. Total ecosystem C increased as soils became more poorly drained, ranging from 181 Mg C ha-1 in the excessively drained Entisol to 547 Mg C ha-1 in the very poorly drained Histosol. The proportion of ecosystem C contained in the soil was much higher in the poorly drained soils, and ranged from 57% in the excessively drained Entisol to 91% in the poorly drained Histosol. While total ecosystem C stocks varied by a factor of three, rates of litterfall and soil respiration were similar among sites. Soil carbon content was highest in the very poorly drained site, and respiration was lowest from this site. During the summer drought of 1999, all soils except the Histosol had lower respiration rates than predicted from temperature alone. Rain events that ended the drought produced a pulse of soil respiration in all mineral soils, stimulating soil C flux more than expected from temperature alone. The effect of drought and rewetting on soil respiration varied by site, suggesting that the response to climate variability will depend upon soil drainage to some extent. Soil respiration rates were most variable in dry conditions, and current and antecedent soil moisture conditions played an important role during those times. In general, soil respiration was much more variable over time than across sites, even among these sites with very different total soil C content, indicating that climate--mainly temperature--is the main determinant of soil CO2 release even across soils with widely varying drainage.

Understanding the determinants and magnitude of variability and uncertainty in this relationship is critical for understanding personal exposures in the evaluation of epidemiological data. The repeated measures regression models presented here address temporal and spatial characteristics of data measured in the 2004-2007 Detroit Exposure and Aerosol Research Study, and they take into account missing data and other data features. The models incorporate turbulence kinetic energy and planetary boundary layer height, meteorological data that are not routinely considered in models that relate central-site concentrations to exposure to health effects. It was found that turbulence kinetic energy was highly statistically significant in explaining the relationship of PM2.5 measured at a particular stationary outdoor air monitoring site with PM2.5 measured outside nearby residences for the temporal coverage of the data.

Many methods rely on the use of standard curves to make estimates of DNA target concentrations in unknown samples. Traditional absolute quantification approaches dictate that a standard curve must accompany each experimental run. However, the generation of a standard curve for each qPCR experiment set-up can be expensive and time consuming, especially for studies with large numbers of unknown samples. As a result, many researchers have adopted a master calibration strategy where a single curve is derived from DNA standard measurements generated from multiple instrument runs. However, a master curve can inflate uncertainty associated with intercept and slope parameters and decrease the accuracy of unknown sample DNA target concentration estimates. Here we report two alternative strategies termed a~pooled' and a~mixed' for the generation of calibration equations from absolute standard curves which can help reduce the cost and time of laboratory testing, as well as the uncertainty in calibration model parameter estimates. In this study, four different strategies for generating calibration models were compared based on a series of repeated experiments for two different qPCR assays using a Monte Carlo Markov Chain method. The hierarchical Bayesian approach allowed for the comparison of uncertainty in intercept and slope model parameters and the optimization of experiment design. Data suggests that the a~pooled' model can reduce uncertainty in both slope and intercept parameter estimates compared to the traditional single curve approach. In addition, the a~mixed' model achieved uncertainty estimates similar to the a~single' model while increasing the number of available reaction wells per instrument run.

Five years (2000-2004) of data from 614 non-polluted, soft-bottom stations from the National Coastal Assessment were analyzed. Multi-dimensional scaling done on Bray-Curtis similarity matrices of species' relative abundance (547 species) suggested seven subregions: two based on salinity (oligohaline, mesohaline) and five based on latitude. Species' distribution patterns for stations with salinities .18 (n=558) were strongly influenced by latitude; Cape Cod was a clear faunal transition zone (R=0.92, p<0.001). Conversely, for stations with salinities <18 (n=56), salinity was the more important factor. An ordination of abiotic variables (temperature, salinity, sediment percent silt-clay, depth) correlated well with the ordination of species' relative abundance data (R=0.77, p<0.001). The first split of a multivariate regression tree was by a summer bottom temperature of 20C at Cape Cod. Salinity and percent silt-clay led to further splits. These results support the existence of Virginian and Transhatteran biogeographic provinces. They constitute a baseline for addressing broad-scale and long-term issues such as global climate change, species invasions, and conservation planning.

An annual aerial SAV monitoring program and a bi-monthly to monthly water quality monitoring program have been conducted throughout Chesapeake Bay since 1984. We performed an analysis of SAV abundance and up to 22 environmental variables potentially influencing SAV growth and abundance (1984-2006). Historically, SAV abundance has changed dramatically in Chesapeake Bay, and since 1984, when SAV abundance was at historic low levels, SAV has exhibited complex changes including long-term (decadal) increases and decreases, as well as some large, single-year changes. Chesapeake Bay SAV was grouped into three broad-scale community-types based on salinity regime, each with their own distinct group of species, and detailed analyses were conducted on these three community-types as well as on seven distinct case-study areas spanning the three salinity regimes. Different trends in SAV abundance were evident in the different salinity regimes. SAV abundance has (a) continually increased in the low-salinity region; (b) increased initially in the medium-salinity region, followed by fluctuating abundances; and (c) increased initially in the high-salinity region, followed by a subsequent decline. In all areas, consistent negative correlations between measures of SAV abundance and nitrogen loads or concentrations suggest that meadows are responsive to changes in inputs of nitrogen. For smaller case-study areas, different trends in SAV abundance were also noted including correlations to water clarity in high-salinity case-study areas, but nitrogen was highly correlated in all areas. Current maximum SAV coverage for almost all areas remain below restoration targets, indicating that SAV abundance and associated ecosystem services are currently limited by continued poor water quality, and specifically high nutrient concentrations, within Chesapeake Bay. The nutrient reductions noted in some tributaries, which were highly correlated to increases in SAV abundance, suggest management activities have already contributed to SAV increases in some areas, but the strong negative correlation throughout the Chesapeake Bay between nitrogen and SAV abundance also suggests that further nutrient reductions will be necessary for SAV to attain or exceed restoration targets throughout the bay.

Recognizing the need to assess the credibility of air quality models in a policy-relevant context, we perform a dynamic evaluation of the Community Multiscale Air Quality (CMAQ) modeling system for the "weekend ozone effect" to determine if observed changes in ozone due to weekday-to-weekend (WDWE) reductions in precursor emissions can be accurately simulated. The weekend ozone effect offers a unique opportunity for dynamic evaluation, as it is a widely documented phenomenon that has persisted since the 1970s. In many urban areas of the Unites States, higher ozone has been observed on weekends than weekdays, despite dramatically reduced emissions of ozone precursors (nitrogen oxides [NOx] and volatile organic compounds [VOCs]) on weekends. More recent measurements, however, suggest shifts in the spatial extent or reductions in WDWE ozone differences. Using 18 years (1988-2005) of observed and modeled ozone and temperature data across the northeastern United States, we re-examine the long-term trends in the weekend effect and confounding factors that may be complicating the interpretation of this trend and explore whether CMAQ can replicate the temporal features of the observed weekend effect. The amplitudes of the weekly ozone cycle have decreased during the 18-year period in our study domain, but the year-to-year variability in weekend minus weekday (WEWD) ozone amplitudes is quite large. Inter-annual variability in meteorology appears to influence WEWD differences in ozone, as well as WEWD differences in VOC and NOx emissions. Because of the large inter-annual variability, modeling strategies using a single episode lasting a few days or a few episodes in a given year may not capture the WEWD signal that exists over longer time periods. The CMAQ model showed skill in predicting the absolute values of ozone concentrations during the daytime. However, early morning NOx concentrations were underestimated and ozone levels were overestimated. Also, the modeled response of ozone to WEWD differences in emissions was somewhat less than that observed. This study reveals that model performance may be improved by (1) properly estimating mobile source NOx emissions and their temporal distributions, especially for diesel vehicles; (2) reducing the grid cell size in the lowest layer of CMAQ; and, (3) using time-dependent and more realistic boundary conditions for the CMAQ simulations.

Part I: Background, emission scenarios and evaluation of meteorological predictions AN - 762267849; 13249813 AB - Under the 11th Five Year Plan (FYP, 2006-2010) for national environmental protection by the Chinese government, the overarching goal for sulfur dioxide (SO2) controls is to achieve a total national emissions level of SO2 in 2010 10% lower than the level in 2005. A similar nitrogen oxides (NOx) emissions control plan is currently under development and could be enforced during the 12th FYP (2011-2015). In this study, the U.S. Environmental Protection Agency (U.S.EPA)'s Community Multi-Scale Air Quality (Models-3/CMAQ) modeling system was applied to assess the air quality improvement that would result from the targeted SO2 and NOx emission controls in China. Four emission scenarios -- the base year 2005, the 2010 Business-As-Usual (BAU) scenario, the 2010 SO2 control scenario, and the 2010 NOx control scenario--were constructed and simulated to assess the air quality change from the national control plan. The Fifth-Generation NCAR/Penn State Mesoscale Model (MM5) was applied to generate the meteorological fields for the CMAQ simulations. In this Part I paper, the model performance for the simulated meteorology was evaluated against observations for the base case in terms of temperature, wind speed, wind direction, and precipitation. It is shown that MM5 model gives an overall good performance for these meteorological variables. The generated meteorological fields are acceptable for using in the CMAQ modeling.

Part II: Evaluation of air quality predictions and air quality benefits assessment AN - 762266079; 13249812 AB - Following the meteorological evaluation in Part I, this Part II paper presents the statistical evaluation of air quality predictions by the U.S. Environmental Protection Agency (U.S. EPA)'s Community Multi-Scale Air Quality (Models-3/CMAQ) model for the four simulated months in the base year 2005. The surface predictions were evaluated using the Air Pollution Index (API) data published by the China Ministry of Environmental Protection (MEP) for 31 capital cities and daily fine particulate matter (PM2.5, particles with aerodiameter less than or equal to 2.5I14m) observations of an individual site in Tsinghua University (THU). To overcome the shortage in surface observations, satellite data are used to assess the column predictions including tropospheric nitrogen dioxide (NO2) column abundance and aerosol optical depth (AOD). The result shows that CMAQ gives reasonably good predictions for the air quality. The air quality improvement that would result from the targeted sulfur dioxide (SO2) and nitrogen oxides (NOx) emission controls in China were assessed for the objective year 2010. The results show that the emission controls can lead to significant air quality benefits. SO2 concentrations in highly polluted areas of East China in 2010 are estimated to be decreased by 30-60% compared to the levels in the 2010 Business-As-Usual (BAU) case. The annual PM2.5 can also decline by 3-15I14gma3 (4-25%) due to the lower SO2 and sulfate concentrations. If similar controls are implemented for NOx emissions, NOx concentrations are estimated to decrease by 30-60% as compared with the 2010 BAU scenario. The annual mean PM2.5 concentrations will also decline by 2-14I14gma3 (3-12%). In addition, the number of ozone (O3) non-attainment areas in the northern China is projected to be much lower, with the maximum 1-h average O3 concentrations in the summer reduced by 8-30ppb.

However, it is often difficult to collect concentration information at each study subject location. In the absence of complete subject-specific measurements, land-use regression (LUR) models have frequently been used for estimating individual levels of exposures to ambient air pollution. The LUR models, however, have several limitations mainly dealing with extensive monitoring data needs and challenges involved in their broader applicability to other locations. In contrast, air quality models can provide high-resolution source-concentration linkages for multiple pollutants, but require detailed emissions and meteorological information. In this study, first we predicted air quality concentrations of PM2.5, NOx, and benzene in New Haven, CT using hybrid modeling techniques based on CMAQ and AERMOD model results. Next, we used these values as pseudo-observations to develop and evaluate the different LUR models built using alternative numbers of (training) sites (ranging from 25 to 285 locations out of the total 318 receptors). We then evaluated the fitted LUR models using various approaches, including: 1) internal "Leave-One-Out-Cross-Validation" (LOOCV) procedure within the "training" sites selected; and 2) "Hold-Out" evaluation procedure, where we set aside 33-293 tests sites as independent datasets for external model evaluation. LUR models appeared to perform well in the training datasets. However, when these LUR models were tested against independent hold out (test) datasets, their performance diminished considerably. Our results confirm the challenges facing the LUR community in attempting to fit empirical response surfaces to spatially- and temporally-varying pollution levels using LUR techniques that are site dependent. These results also illustrate the potential benefits of enhancing basic LUR models by utilizing air quality modeling tools or concepts in order to improve their reliability or transferability.

In addition, our data reveal the presence of three well supported but previously unrecognized clades of A. valida among specimens in the north-eastern Pacific. Different species of Jassa and different genetic lineages of Ampithoe exhibit striking disparity in geographic distribution across the region as well as substantial differences in genetic diversity indices.Main conclusions Molecular genetic methods greatly improve the accuracy and resolution of identifications for invasive benthic marine amphipods at the species level and below. Our data suggest that multiple cryptic introductions of Ampithoe have occurred in the north-eastern Pacific and highlight uncertainty regarding the origin and invasion histories of both Jassa and Ampithoe species. Additional morphological and genetic analyses are necessary to clarify the taxonomy and native biogeography of both amphipod genera.

AN - 749020921; 20573408 AB - Various assays with adult fish have been developed to identify potential endocrine-disrupting chemicals (EDCs) which may cause toxicity via alterations in the hypothalamic-pituitary-gonadal (HPG) axis. These assays can be sensitive and highly diagnostic for key mechanisms such as agonism of the estrogen and androgen receptors (ERs, ARs) and inhibition of steroid synthesis. However, most of the tests do not unambiguously identify AR antagonists. The purpose of this work was to explore the utility of a mixture test design with the fathead minnow (Pimephales promelas) for detecting different classes of EDCs including AR antagonists. Adults of both sexes were exposed via the water to EDCs with diverse mechanisms of action in the absence or presence of 17beta-trenbolone (TB), a potent AR agonist which masculinizes female fathead minnows. Similar to previous studies with the model AR antagonists flutamide and vinclozolin, exposure of females to the AR antagonist cyproterone acetate in the presence of TB decreased expression of an easily-observed masculinization response, nuptial tubercle formation. Mixture studies with TB and the model ER agonists, 17alpha-ethinylestradiol and bisphenol A, also showed inhibition of tubercle formation in the females, but unlike the AR antagonists, the estrogens markedly induced synthesis of vitellogenin (VTG: egg yolk protein), particularly in males. The ER agonists also offset TB-induced depressions in plasma VTG concentrations in female fish. Additional mixture experiments were conducted with TB and triclocarban, an anti-microbial reported to enhance AR-mediated responses, or ammonia, a "negative control" with no known direct effects on HPG function. Neither chemical affected VTG status in males or females in the absence or presence of TB; however, both slightly enhanced TB-induced tubercle formation in females. Based on studies described herein and elsewhere with the fathead minnow, a TB co-exposure assay appears to be an effective approach for clearly identifying AR antagonists as well as potential EDCs with other relevant mechanisms of action.

AN - 748955343; 20558277 AB - Risk assessments are typically conducted on a chemical-by-chemical basis; however, many regulatory bodies are developing frameworks for assessing the cumulative risk of chemical mixtures of chemicals. The current investigation examined how chemicals that disrupt rat sex differentiation via two diverse mechanisms disrupt F1 male rat reproductive development, when administered together orally on days 14-18 of gestation. Experiment 1 used a mixture of 50 mg/kg-d procymidone and 500 mg/kg-d dibutyl phthalate (DBP), whereas experiment 2 used 150 mg/kg-d procymidone and 1125 mg/kg-d DBP (top dose), or 0, 4.17, 8.33, 16.7, 33.3, 50, 66.7, and 83.3% of the top dose. When we compared the dose and response addition predictions to the observed effects we found that dose addition models were more accurate than response addition models, indicating that compounds that act by different mechanisms of toxicity produce cumulative dose-additive effects.

AN - 748945859; 20398750 AB - Following the passage of the Food Quality Protection Act, which mandated an increased focus on evaluating the potential toxicity of pesticides to children, the number of guideline developmental neurotoxicity (DNT) studies (OPPTS 870.6300) submitted to the U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs (OPP) was greatly increased. To evaluate the impact of available DNT studies on individual chemical risk assessments, the ways in which data from these studies are being used in pesticide risk assessment were investigated. In addition, the neurobehavioral and neuropathological parameters affected at the lowest observed adverse effect level (LOAEL) for each study were evaluated to ascertain whether some types of endpoints were consistently more sensitive than others. As of December 2008, final OPP reviews of DNT studies for 72 pesticide chemicals were available; elimination of studies with major deficiencies resulted in a total of 69 that were included in this analysis. Of those studies, 15 had been used to determine the point of departure for one or more risk assessment scenarios, and an additional 13 were determined to have the potential for use as a point of departure for future risk assessments (selection is dependent upon review of the entire database available at the time of reassessment). Analysis of parameters affected at the study LOAELs indicated that no single parameter was consistently more sensitive than another. Early assessment time points (e.g., postnatal day (PND) 11/21) tended to be more sensitive than later time points (e.g., PND 60). These results demonstrate that data generated using the current guideline DNT study protocol are useful in providing points of departure for risk assessments. The results of these studies also affirm the importance of evaluating a spectrum of behavioral and neuropathological endpoints, in both young and adult animals, to improve the detection of the potential for a chemical to cause developmental neurotoxicity.

This monitoring programme was designed to provide a baseline prior to environmental improvements being undertaken to reduce pollutant loads returned to the river. Pollutant (Escherichia coli, total nitrogen, oxidised nitrogen, total phosphorus, filtered reactive phosphorus and total organic carbon) concentrations were significantly (p<0.01) higher in the drainage water than the river water and increased during the irrigation season. Salt concentrations were also significantly (p<0.01) higher in the drainage water than the river inflow water but decreased during the irrigation season because of dilution of the saline groundwater inputs. Pollutant loads exported to the river were significantly higher (p<0.01-0.05) during the irrigation season for all water quality parameters except oxidised nitrogen. Levels of oxidised nitrogen, filtered reactive phosphorus and E. coli increased in the river downstream of the where the agricultural pollutant inputs begin. Load calculations indicated that this increased water pollution is likely due to the pollutant contributions from the flood-irrigated areas and biogeochemical processing of dissolved nutrients in the river.

These seven refineries are designed to produce from 330,000 to 100 million gal of ethanol per year. The overall average estimated air emission rates for criteria, hazardous, and greenhouse gas pollutants at the 7CEDF are shown here in terms of tons per year and pounds per gallon of ethanol produced. Water use rates estimated for the cellulosic ethanol refineries are also noted. The air emissions are then compared with similar estimates from a U.S. cellulosic ethanol pilot plant, a commercial Canadian cellulosic ethanol refinery, four commercial U.S. corn ethanol refineries, and U.S. petroleum refineries producing gasoline. The U.S. Environmental Protection Agency (EPA) air pollution rules that may apply to cellulosic ethanol refineries are also discussed. Using the lowest estimated emission rates from these cellulosic ethanoi demonstration facilities to project air emissions, EPA's major source thresholds for criteria and hazardous air pollutants might not be exceeded by cellulosic ethanol refineries that produce as high as 25 million gal per year of ethanol (95 ML). Emissions are expected to decrease at cellulosic ethanol refineries as the process matures and becomes more commercially viable.

Several of these contaminants that are not able to bind to mammalian estrogen receptors (such as atrazine and cyanazine) have previously been reported to bind to the alligator estrogen receptor from oviductal tissue. Binding of known Lake Apopka contaminants to full length estrogen receptors alpha from human (hER) and alligator (aER) was assessed in a side-by-side comparison within the same assay system. Baculovirus-expressed recombinant hERand aERwere used in a competitive binding assay. Atrazine and cyanazine were not able to bind to either receptor. p,p'-Dicofol was able to bind to aERwith a concentration inhibiting 50% of binding (IC50) of 4 [mu]M, while only partially displacing 17 beta -estradiol (E2) from hERand yielding a projected IC50 of 45 [mu]M. Chemicals that only partially displaced E2 from either receptor, including some dichlorodiphenyltrichloroethane (DDT) metabolites and trans-nonachlor, appeared to have higher affinity for aERthan hER. p,p'-Dicofol-mediated transcriptional activation through aERand hERwas assessed to further explore the preferential binding of p,p'-dicofol to aERover hER. p,p'-Dicofol was able to stimulate transcriptional activation in a similar manner with both receptors. However, the in vitro results obtained with p,p'-dicofol were not reflected in an in vivo mammalian model, where Kelthane[TM] (mixed o,p'- and p,p'-dicofol isomers) did not elicit estrogenic effects. In conclusion, although there was no evidence of exclusively species-specific estrogen receptor binders, some xenoestrogens, especially p,p'-dicofol, had a higher affinity for aERthan for hER.

There are two sealant types generally used in the United States today: asphalt emulsion and coal tar emulsion. Coal tar is a suspected human carcinogen and is detrimental to the health of a variety of organisms. Runoff from these surfaces may be a significant source of polycyclic aromatic hydrocarbons (PAHs) to the environment. The results from a field study of PAH concentrations and potential toxicity of runoff from asphalt surfaces sealed with coal tar sealant and asphalt emulsion sealant will be presented. The study assessed exposure concentrations and evaluated the short-term effects of leached PAHs on potential toxicity to receiving waters. The field study was conducted on an actively-used asphalt parking lot at EPA's Urban Watershed Research Facility (UWRF) in Edison, NJ. The lot was divided into three test plots: one sealed with coal tar sealant, one coated with asphalt emulsion sealant, and an unsealed control. Collected rainwater was homogenized and delivered to the plots for each test. Samples were collected immediately after running off the asphalt, as well as after mixing downstream at the end of a common trench drain. This was done in order to compare runoff from sealed asphalt surfaces to that which has been mixed and transported downstream.

In collaboration with the Unilever Research India, a series of microbial tests were conducted on a Unilever Pureit super(TM) microbiological purifier for household drinking water at the EPA's Test and Evaluation Facility in Cincinnati, Ohio. The Pureit super(TM) water treatment system is fed by gravity and combines the unit operations of physical filtration, chlorine disinfection, and carbon adsorption for treating drinking water. EPA evaluated the Pureit super(TM) device for removal of E. coli (as a surrogate for bacteria), and MS2 bacteriophage (as a surrogate for viruses). Results demonstrated that the Pureit super(TM) system achieved EPA requirements of a 6 log reduction of bacteria and a 4 log reduction of virus for a "Microbiological Purifier" throughout the design life of the device ( similar to 2250 liters). The final polisher of the unit was capable of reducing the residual chlorine concentration to less than the EPA's 2 mg/L maximum limit for tap water.

The NO sub(x) bias been shown in model evaluations using aircraft data (Singh et al., 2007) and total column NO sub(2) (molecules cm super(-2)) from satellite observations (Napelenok et al., 2008). The causes of NO sub(x) underpredictions have yet to be fully understood due to the interconnected nature of simulated emission, transport, and chemistry processes. Recent observation-based studies suggest that, in the upper troposphere, simulated chemistry overpredicts hydrogen radicals (OH super(; ) and HO sub(2) super(; )) and would convert NO sub(x) to HNO sub(3) too quickly (Olson et al., 2006; Bertram et al., 2007; Ren et al., 2008). Since typical chemistry evaluation techniques are not available for upper tropospheric conditions, this study develops an evaluation platform from in situ observations, stochastic convection, and deterministic chemistry. We derive a stochastic convection model and optimize it using two simulated datasets of time since convection, one based on meteorology and the other on chemistry. The chemistry surrogate for time since convection is calculated using seven different chemical mechanisms, all of which predict shorter time since convection than our meteorological analysis. We evaluate chemical simulations by inter-comparison and by pairing results with observations based on NO sub(x):HNO sub(3), a photochemical aging indicator. Inter-comparison reveals individual chemical mechanism biases and recommended updates. Evaluation against observations shows that all chemical mechanisms overpredict NO sub(x) removal relative to long-lived methanol and carbon monoxide. All chemical mechanisms underpredict observed NO sub(x) by at least 30%, and further evaluation is necessary to refine simulation sensitivities to initial conditions and chemical rate uncertainties.

We examined the relationship between water intake measures and adverse birth outcomes in participants from three study sites in the United States. Using a prospective cohort study, we examined daily intake of bottled, cold tap, total tap, and total water in relation to birth weight and risk of small-for-gestational-age (SGA) among term births and risk of preterm delivery. Based on water consumption data collected between 20-24 weeks of gestation, the adjusted mean birth weight was 27 (95% confidence interval [CI]: -34, 87), 39 (95% CI: -22, 99), and 50 (95% CI: -11, 110) grams higher for the upper three total water intake quartiles (> 51-78, > 78-114, and > 114 ounces/day) compared to the lowest quartile (, 51 ounces/day). Adjusted birth weight results were similar for bottled water, cold tap water, and total tap water intake. An exposure-response gradient was not detected for either preterm delivery or SGA with increasing total water intake and total tap water intake, but adjusted relative risks for all three upper quartiles were below 1.0 (range: 0.6-0.9) for SGA. These data suggest that high water intake may be associated with higher mean birth weight following adjustment for confounding.

Including socioeconomic variables further complicates assessments. While statistical or process-based regional environmental assessment models may be computationally or financially expensive, we propose a simple nonparametric outcomes-based approach using a directional distance function from the efficiency and productivity analysis literature. The regional environmental-economic directional distance function characterizes the relative efficiency of geographic units in combining multiple inputs to produce multiple desirable and undesirable socioeconomic and environmental outputs. This function makes no assumptions about the functional relationships among variables, but by quantifying the extent to which desirable outputs can be expanded and inputs and undesirable outputs contracted, the function can help decisionmakers identify the most important broad-scale management and restoration opportunities across a heterogeneous region. A case study involving 134 watersheds in the Mid-Atlantic region of the USA indicates that, depending on which outputs are specified as desirable in the models, 25%-33% of the watersheds are efficient in producing desirable outputs while minimizing inputs and undesirable outputs. Models including socioeconomic indicators exhibit increased watershed efficiency compared to models using only environmental indicators. Efficiency levels appear to be correlated with ecoregions.

AN - 754564582; 13399782 AB - This paper examines a proposal to incorporate the use of wetlands in water quality trading (WQT) programs in order to meet national wetlands goals and advance WQT. It develops a competitive WQT model wherein wetland services are explicitly considered. To participate in a WQT program, an agricultural producer could employ wetlands as his nutrient management practice. Unlike most other management practices, wetlands not only remove nutrients from agricultural runoff but also provide ancillary benefits like wildlife habitat and flood control that do not exclusively accrue to the farmer. Thus, when appropriate, a WQT program should be coupled with additional incentives for wetland creation and restoration, such as using a wetland subsidy. Despite the water quality enhancement properties of wetlands, the model reveals that implementing a wetland subsidy will not necessarily translate into water quality improvements. While wetland creation is externally incentivized, the farm's opportunity cost of fertilizer usage in the WQT market is also reduced. In this sense, a wetland subsidy acts like a fertilizer subsidy. Conditions under which a wetland subsidy will help expand WQT include some degree of farmland area fixity, which is resembled in some, but not all, watersheds, and high efficiency of the wetland abatement technology.

The Salmonella mammalian microsome mutagenicity assay has been central to the field of genetic toxicology since the 1970s. Here we document the paradigm shifts engendered by the assay, the validation and applications of the assay, and how the assay is a model for future in vitro toxicology assays. We searched PubMed, Scopus, and Web of Knowledge using key words relevant to the Salmonella assay and additional genotoxicity assays. We merged the citations, removing duplicates, and categorized the papers by year and topic. The Salmonella assay led to two paradigm shifts: that some carcinogens were mutagens and that some environmental samples (e.g., air, water, soil, food, combustion emissions) were mutagenic. Although there are > 10,000 publications on the Salmonella assay, covering tens of thousands of agents, data on even more agents probably exist in unpublished form, largely as proprietary studies by industry. The Salmonella assay is a model for the development of 21st century in vitro toxicology assays in terms of the establishment of standard procedures, ability to test various agents, transferability across laboratories, validation and testing, and structure-activity analysis.

The first of these (December 2004) was the most severe and caused important geomorphic changes in the Riu Flumineddu watershed where the influence of human activity is limited. The hydrological characterisation of this flood is extremely difficult because of the lack of streamflow gauges and the relative paucity of meteorological stations in the region. Peak discharge of the fluviokarstic Riu Flumineddu Canyon has been estimated based on a distributed hydrological model (TOPKAPI) and on empirical methods based on geomorphic and sedimentological observations. The comparison between the results derived from these independent methods allows us to obtain the best possible estimate of peak discharge. Differences between modelled and measured peak flows can be attributed to water losses and/or gains along the river channel from interactions with the underground karst drainage network. The December 2004 flood, with an estimated recurrence interval of at least 65 years, generated overbank flow and destroyed several bridges in upstream reaches, caused important changes in channel morphology and sediment distribution and was able to move boulders up to 1 m in diameter in downstream reaches.

Because of limitations of currently used approaches for evaluating regional air quality models, a framework for model evaluation is introduced here for determining the suitability of a modeling system for a given application, distinguishing the performance between different models through confidence-testing of model results, guiding model development and analyzing the impacts of regulatory policy options. The framework identifies operational, diagnostic, dynamic, and probabilistic types of model evaluation. Operational evaluation techniques include statistical and graphical analyses aimed at determining whether model estimates are in agreement with the observations in an overall sense. Diagnostic evaluation focuses on process-oriented analyses to determine whether the individual processes and components of the model system are working correctly, both independently and in combination. Dynamic evaluation assesses the ability of the air quality model to simulate changes in air quality stemming from changes in source emissions and/or meteorology, the principal forces that drive the air quality model. Probabilistic evaluation attempts to assess the confidence that can be placed in model predictions using techniques such as ensemble modeling and Bayesian model averaging. The advantages of these types of model evaluation approaches are discussed in this paper.

However, because of its hazardous properties, the unreacted ClO2 gas must be contained and captured during fumigation events. Although activated carbon has been used during some decontamination events to capture the ClO2 gas, no data are available to quantify the performance of the activated carbon in terms of adsorption capacity and other sorbent property operational features. Laboratory experiments were conducted to determine and compare the ClO2 adsorption capacities of five different types of activated carbon as a function of the challenge ClO2 concentration. Tests were also conducted to investigate other sorbent properties, including screening tests to determine gaseous species desorbed from the saturated sorbent upon warming (to provide an indication of how immobile the ClO2 gas and related compounds are once captured on the sorbent). In the adsorption tests, ClO2 gas was measured continuously using a photometric-based instrument, and these measurements were verified with a noncontinuous method utilizing wet chemistry analysis. The results show that the simple activated carbons (not impregnated or containing other activated sorbent materials) were the most effective, with maximum adsorption capacities of approximately 110 mg/g. In the desorption tests, there was minimal release of ClO2 from all sorbents tested, but desorption levels of chlorine (CI2) gas (detected as chloride) varied, with a maximum release of nearly 15% of the mass of ClO2 adsorbed.

Here, we assess the degree to which kinetic limitations, size exclusion effects, and electrostatic repulsions impaired PCB sorption to activated carbon. Sorption of 11 PCB congeners with activated carbon was studied in fixed bed reactors with organic-free water (OFW) and Suwannee River natural organic matter (SR-NOM), made by reconstituting freeze-dried SR-NOM at a concentration of 10 mg L (super -1) as carbon. In the OFW test, no PCBs were detected in the column effluent over the 390-d study, indicating that PCB-activated carbon equilibrium sorption capacities may be achieved before breakthrough even at the relatively high hydraulic loading rate (HLR) of 3.1 m h (super -1) . However, in the SR-NOM fixed-bed test, partial PCB breakthrough occurred over the entire 320-d test (HLRs of 3.1-, 1.5-, and 0.8 m h (super -1) ). Simulations from a modified pore and surface diffusion model indicated that external (film diffusion) mass transfer was the dominant rate-limiting step but that internal (pore diffusion) mass transfer limitations were also present. The external mass transfer limitation was likely caused by formation of PCB-NOM complexes that reduced PCB sorption through a combination of (i) increased film diffusion resistance; (ii) size exclusion effects; and (iii) electrostatic repulsive forces between the PCBs and the NOM-coated activated carbon. However, the seepage velocities in the SR-NOM fixed bed test were about 1000 times higher than would be expected in a sediment cap. Therefore, additional studies are needed to assess whether the mass transfer limitations described here would be likely to manifest themselves at the lower seepage velocities observed in practice.

It is recognized that the short list of impact categories has remained fairly constant, even after extensive discussions. The termination point of impact assessment modeling (e.g., inventory, midpoint, endpoint, damage, single score) has been discussed extensively, and the advantages and disadvantages of these different levels are well published. Early LCIAs were conducted independent of system location, but now site-specificity has been a research topic for many of the local and regional categories (e.g., acidification, eutrophication, and smog formation). In reality, even though many advances have been made in site-specific analysis, the life cycle assessment (LCA) case studies are often limited to their inventory data, and as a result, most LCAs are still site-generic even though the LCIA methodologies exist to allow for site-specific analysis. Pollutant-based impacts have received the most research effort and support in the past, but resource depletion categories (e.g., land use and water use) are now recognized as being highly complex, site-specific, data intensive, and important for contributing toward the sustainability of the planet. Efforts in these categories are still in the neophyte stages and are expected to have the greatest advances in the upcoming years.

This evaluation effort focused on weekday morning rush hours since urban NOX concentrations are strongly influenced by the significant loading of emissions associated with heavy commuter traffic. On-road vehicle NOX emissions generated by the MOBILE6 model revealed a steady decline with an overall decrease of 25% for 2002-2006. In this study, a dynamic model evaluation was undertaken that entails an assessment of the predicted concentration response of the Community Multiscale Air Quality (CMAQ) model due to changes in NOX emissions as well as to meteorological variability spanning 3-month summer periods over five consecutive years (2002-2006) against observed concentration changes at NOX monitoring sites located primarily in urban areas of the eastern United States. Both modeled and observed hourly NOX concentrations exhibited maximum values that coincided with the morning peak NOX emissions. The notable results, based on 3-h average (6-9 AM local time) NOX concentrations, derived between the 50th and 95th percentiles of cumulative concentration distributions, revealed that modeled changes at these elevated NOX levels generally tracked the year-to-year variations in the observed concentration changes. When summer 2002 values were used as a reference, both modeled and observed results also showed definitive decreases in weekday morning urban NOX concentrations over this multi-year period, which can be primarily attributed to the reductions in mobile source emissions. Whereas observed NOX concentrations have declined by about 25% over this period consistent with the decline in the modeled mobile emission sector, modeled NOX concentration changes were close to the decreases exhibited in all (mobileaa+aaother sectors) surface NOX emissions whose overall decline was about 15% over this multi-year period.

One-half the trees were exposed to elevated O3 for 6aayrs prior to and during the experiment. Soil-gas sampling wells were placed at 8 and 15aacm and soil CO2 was sampled during labeling in mid-late August, 2006. In beech, I13CO2 at both depths decreased approximately 50aah after labeling, reflecting rapid translocation of fixed C to roots and release through respiration. In spruce, label was detected in fine-root tissue, but there was no evidence of label in I13CO2. The results show that C fixed in the canopy rapidly reaches respiratory pools in beech roots, and suggest that spruce may allocate very little of recently-fixed carbon into root respiration during late summer. A change in carbon allocation belowground due to long-term O3 exposure was not observed. Below-ground carbon allocation in mature beech and spruce exposed to ozone.

The carbon stable isotope ratio ( delta 13C) is widely used in food web studies, but it must be corrected to remove variability associated with varying lipid content in the tissue. A lipid correction has not been determined for any deep-sea fish. These fishes are ideal for studying lipid correction because lipid content varies widely among species. Our objective was to evaluate an application of a mass balance delta 13C correction to a taxonomically diverse group of deep-sea fishes by determining the effect of lipid extraction on the stable isotope ratios, examining the quality of the model parameters derived for the mass balance correction, and comparing the correction to published results. We measured the lipid extraction effect on the nitrogen stable isotope ratio ( delta 15N) and delta 13C of muscle tissue from 30 North Atlantic species. Lipid extraction significantly increased tissue delta 15N (+0.66) and delta 13C values, but the treatment effect on delta 13C was dependent on C:N, a proxy for lipid content. We compared the lipid-extracted delta 13C to the delta 13C predicted by the mass balance correction using model variables estimated from either all individuals (pooled) or species-by-species or using published values from other species. The correction using the species-by-species approach performed best; however, all three approaches produced corrected values that were generally within 0.5 of the measured lipid-free delta 13C and that had a small over-all bias (8).

In many cases these smaller communities have no established stormwater utility, and are investigating alternatives for complying with these new, sometimes expensive requirements. We note that it might be cost effective for some communities to encourage homeowners to control stormwater runoff at the parcel level instead of, or in conjunction with more traditional large, infrastructural best management practices (BMP). We go onto argue that in the absence of a strict regulatory cap, an auction is a cost-effective tool for implementing controls on stormwater runoff quantity at the parcel level. In this paper, we test the effectiveness of a procurement auction as the coordinating mechanism for encouraging installation of parcel-scale rain gardens and rain barrels within a small suburban watershed in the Midwest. The auction, which was conducted in spring 2007 and 2008, resulted in installation of 81 gardens and 165 barrels on 107 of the 350 eligible properties. Average cost per liter of runoff detention in both years was $0.36 for gardens and $0.59 for barrels. Interestingly, approximately 55% of the bids were for $0, suggesting that an educational campaign may result in substantial runoff mitigation if utilities paid for the installation of stormwater management practices. However, we found that an auction promoted more participation than education alone and at a cheaper per-unit control cost than a flat stormwater control payment plan. Overall, this study demonstrates that relatively minimal financial incentives can result in homeowners' willingness-to-accept stormwater management practices on their property, thus opening an important avenue for retrofitting watersheds that are largely in private ownership.

The biological effect of this anti-neoplastic agent is dependent on its coordination of iron with subsequent oxidant generation. In lung cells, divalent metal transporter 1 (DMT1) can participate in metal transport resulting in control of an oxidative stress and tissue damage. We tested the postulate that metal import by DMT1 would participate in preventing lung injury after exposure to bleomycin. Microcytic anemia (mk/mk) mice defective in DMT1 and wild-type mice were exposed to either bleomycin or saline via intratracheal instillation and the resultant lung injury was compared. Twenty-four h after instillation, the number of neutrophils and protein concentrations after bleomycin exposure were significantly elevated in the mk/mk mice relative to the wild-type mice. Similarly, levels of a pro-inflammatory mediator were significantly increased in the mk/mk mice relative to wild-type mice following bleomycin instillation. Relative to wild-type mice, mk/mk mice demonstrated lower non-heme iron concentrations in the lung, liver, spleen, and splenic, peritoneal, and liver macrophages. In contrast, levels of this metal were elevated in alveolar macrophages from mk/mk mice. We conclude that DMT1 participates in the inflammatory lung injury after bleomycin with mk/mk mice having increased inflammation and damage following exposure. This finding supports the hypothesis that DMT1 takes part in iron detoxification and homeostasis in the lung.

This study evaluated UV-irradiated oocysts by three assays: a SCID mouse bioassay, an in vitro T. gondii oocyst plaque (TOP) assay, and a quantitative reverse transcriptase real-time PCR (RT-qPCR) assay. The results from the animal bioassay show that 1- and 3-log10 inactivation is achieved with 4 mJ/cm2 UV and 10 mJ/cm2 low-pressure UV, respectively. TOP assay results, but not RT-qPCR results, correlate well with bioassay results. In conclusion, a 3-log10 inactivation of T. gondii oocysts is achieved by 10-mJ/cm2 low-pressure UV, and the in vitro TOP assay is a promising alternative to the mouse bioassay.

AN - 748984119; 20602530 AB - The Deepwater Horizon oil spill has led to the use of >1 M gallons of oil spill dispersants, which are mixtures of surfactants and solvents. Because of this large scale use there is a critical need to understand the potential for toxicity of the currently used dispersant and potential alternatives, especially given the limited toxicity testing information that is available. In particular, some dispersants contain nonylphenol ethoxylates (NPEs), which can degrade to nonylphenol (NP), a known endocrine disruptor. Given the urgent need to generate toxicity data, we carried out a series of in vitro high-throughput assays on eight commercial dispersants. These assays focused on the estrogen and androgen receptors (ER and AR), but also included a larger battery of assays probing other biological pathways. Cytotoxicity in mammalian cells was also quantified. No activity was seen in any AR assay. Two dispersants showed a weak ER signal in one assay (EC50 of 16 ppm for Nokomis 3-F4 and 25 ppm for ZI-400). NPs and NPEs also had a weak signal in this same ER assay. Note that Corexit 9500, the currently used product, does not contain NPEs and did not show any ER activity. Cytotoxicity values for six of the dispersants were statistically indistinguishable, with median LC50 values approximately 100 ppm. Two dispersants, JD 2000 and SAF-RON GOLD, were significantly less cytotoxic than the others with LC50 values approaching or exceeding 1000 ppm.

Log-log relationships have been consistently observed between trace metal and reference metal concentrations and are often considered constant. Consequently, we used a regional geochemistry data set to evaluate background trace metal/Fe log-log associations across soils with highly diverse composition. Our results indicate that, although geochemical associations may be proportional, they significantly differ across predominant United States Department of Agriculture (USDA) soil orders. This suggests that highly complex interactions between soil-forming factors and variable secondary clay mineral composition affect the ratio of trace metals to Fe concentrations in soils. Also, intra-order variability in trace metal/Fe ratios generally ranged multiple orders of magnitude which suggest that the order level of the USDA soil taxonomic system is insufficient to reasonably classify background trace metal concentrations. Consequently, geochemical association plots are a useful screening tool for environmental site assessments, but ubiquitous application of generic background metal data sets could result in erroneous conclusions. Because significantly different ratios were observed across predominant USDA soil orders, an agglomerative clustering technique was used to elucidate hierarchical patterns of association. We present these results as a mechanism to aid environmental assessors in screening candidate background metal data sets for their applicability to site-specific soil composition; although site-specific background metal data should be utilized if ample pristine reference sites with similar (i.e., sub-order) soil composition can be identified and sampled.

AN - 733161125; 20399226 AB - Microelectrode arrays (MEAs) have been in use over the past decade and a half to study multiple aspects of electrically excitable cells. In particular, MEAs have been applied to explore the pharmacological and toxicological effects of numerous compounds on spontaneous activity of neuronal and cardiac cell networks. The MEA system enables simultaneous extracellular recordings from multiple sites in the network in real time, increasing spatial resolution and thereby providing a robust measure of network activity. The simultaneous gathering of action potential and field potential data over long periods of time allows the monitoring of network functions that arise from the interaction of all cellular mechanisms responsible for spatio-temporal pattern generation. In these functional, dynamic systems, physical, chemical, and pharmacological perturbations are holistically reflected by the tissue responses. Such features make MEA technology well suited for the screening of compounds of interest, and also allow scaling to high throughput systems that can record from multiple, separate cell networks simultaneously in multi-well chips or plates. This article is designed to be useful to newcomers to this technology as well as those who are currently using MEAs in their research. It explains how MEA systems operate, summarizes what systems are available, and provides a discussion of emerging mathematical schemes that can be used for a rapid classification of drug or chemical effects. Current efforts that will expand this technology to an influential, high throughput, electrophysiological approach for reliable determinations of compound toxicity are also described and a comprehensive review of toxicological publications using MEAs is provided as an appendix to this publication. Overall, this article highlights the benefits and promise of MEA technology as a high throughput, rapid screening method for toxicity testing. (c) 2010 Elsevier Inc. All rights reserved.

The model consists of six tissue compartments corresponding to the brain, liver, kidney, gut, red blood cells, and remaining carcass. Additional compartments describe the elimination of CH sub(3)Hg to eggs and growing feathers. Dietary uptake of CH sub(3)Hg was modeled as a diffusion-limited process, and the distribution of CH sub(3)Hg among compartments was assumed to be mediated by the flow of blood plasma. To the extent possible, model parameters were developed using information from American kestrels. Additional parameters were based on measured values for closely related species and allometric relationships for birds. The model was calibrated using data from dietary dosing studies with American kestrels. Good agreement between model simulations and measured CH sub(3)Hg concentrations in blood and tissues during the loading phase of these studies was obtained by fitting model parameters that control dietary uptake of CH sub(3)Hg and possible hepatic demethylation. Modeled results tended to underestimate the observed effect of egg production on circulating levels of CH sub(3)Hg. In general, however, simulations were consistent with observed patterns of CH sub(3)Hg uptake and elimination in birds, including the dominant role of feather molt. This model could be used to extrapolate CH sub(3)Hg kinetics from American kestrels to other bird species by appropriate reassignment of parameter values. Alternatively, when combined with a bioenergetics-based description, the model could be used to simulate CH sub(3)Hg kinetics in a long-term environmental exposure.

15040320 AB - Dates of special, historical significance, such as the 50th anniversary of the founding of the Teratology Society, prompt a desire to pause and look back and contemplate where we began, how far we have come, and consider the future for our scientific endeavors. The study of the etiology of cleft palate extends many years into the past and was a subject of interest to many of the founding members of the Teratology Society. This research area was intensively pursued and spawned a vast portfolio of published research. This article will look back at the state of the science around the time of the founding of the Teratology Society, in the 1950s and 1960s, and track the emergence and pursuit of an interest in an etiology for cleft palate involving failure of palatal fusion. Studies of medial epithelial cell fate and induction of cleft palate by interference with adhesion or fusion span the period from the 1960s to the present time. Teratology Society members have been and continue to be key players in cleft palate research. In this retrospective article, seminal research published by Teratology Society members will serve as a platform to launch the discussion of the emergence of our current understanding of medial epithelial cell differentiation and fate and the potential for these processes to be targets of teratogenic action.

Consequently, there are few examples where the etiology of birth defects caused by a specific agent has been well described. One such example is the 'Edema Syndrome' first described by Casimer Grabowski in the 1960s as a mechanism of hypoxia-induced malformations in the chick embryo. The Edema Syndrome comprised a series of events in the embryo starting with osmotic imbalances followed by edema, distention, blisters, hematomas, and hemorrhage in or near developing structures. Malformation or deformation of structures resulted from mechanical disruption or loss of blood supply. A similar etiology has since been described by others in a variety of laboratory mammals following treatment with drugs including epinephrine, hydroxyurea, cocaine, phenytoin, and potassium channel-blocking drugs. Free radical excess following transient hypoxia may be a common factor in all of these insults. Vascular disruption is also associated with a number of birth defects in humans, including limb and digit reduction defects and urogenital defects. Birth Defects Res (Part B) 89:300-303, 2010.

The fire growth index, total heat release amount index, total smoke release amount index and toxicity product index were calculated, based on which an index system for evaluating fire hazard was set up. All factors in this index system had been analyzed by the analytic hierarchy process, and the specific weight for each factor had been determined. Then fire hazard of thermoplastics was evaluated considering integrated fire hazard index. The results show that fire hazards of HIPS-phosphate fire retardant (PFR), PVC-non-flame retardant, ABS-brominated flame retardant (BFR) and PC/ABS-PFR are higher than PC-BFR and PP-non-halogenated flame retardant.

Iron hydroxy carbonate (chukanovite) is frequently observed as a secondary mineral precipitate in granular iron PRBs. Mineralogical characterization was carried out using X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and X-ray absorption spectroscopy on materials collected from three field-based PRBs in the US (East Helena, MT; Elizabeth City, NC; Denver Federal Center, CO). These PRBs were installed to treat a range of contaminants, including chlorinated organics, hexavalent chromium, and arsenic. Results obtained indicate that chukanovite is a prevalent secondary precipitate in the PRBs. Laboratory experiments on high-purity chukanovite separates were carried out to constrain the room-temperature solubility for this mineral. An estimated Gibbs energy of formation (f GA) for chukanovite is 1174.4 plus or minus 6kJ/mol. A mineral stability diagram is consistent with observations from the field. Water chemistry from the three reactive barriers falls inside the predicted stability field for chukanovite, at inorganic carbon concentrations intermediate to the stability fields of siderite and ferrous hydroxide.

AN - 733161067; 20346927 AB - Benzo[a]pyrene (B[a]P) is a potent human and rodent lung carcinogen. This activity has been ascribed in part to the formation of anti-trans-7,8-dihydroxy-7,8-dihydroB[a]P-9,10-epoxide (BPDE)-DNA adducts. Other carcinogenic mechanisms have been proposed: (1) the induction of apurinic sites from radical cation processes, and (2) the metabolic formation of B[a]P-7,8-quinone (BPQ) that can form covalent DNA adducts or reactive oxygen species which can damage DNA. The studies presented here sought to examine the role of stable BPQ-DNA adducts in B[a]P-induced mouse lung tumorigenesis. Male strain A/J mice were injected intraperitoneally once with BPQ or trans-7,8-dihydroxy-7,8-dihydroB[a]P (BP-7,8-diol) at 30, 10, 3, or 0mg/kg. Lungs and livers were harvested after 24h, the DNA extracted and subjected to (32)P-postlabeling analysis. Additional groups of mice were dosed once with BPQ or BP-7,8-diol each at 30 mg/kg and tissues harvested 48 and 72 h later, or with B[a]P (50mg/kg, a tumorigenic dose) and tissues harvested 72 h later. No BPQ or any other DNA adducts were observed in lung or liver tissues 24, 48, or 72 h after the treatment with 30 mg/kg BPQ. BP-7,8-diol gave BPDE-DNA adducts at all time points in both tissues and B[a]P treatment gave BPDE-DNA adducts in the lung. In each case, no BPQ-DNA adducts were detected. Mouse body weights significantly decreased over time after BPQ or BP-7,8-diol treatments suggesting that systemic toxicity was induced by both agents. Model studies with BPQ and N-acetylcysteine suggested that BPQ is rapidly inactivated by sulfhydryl-containing compounds and not available for DNA adduction. We conclude that under these treatment conditions BPQ does not form stable covalent DNA adducts in the lungs or livers of strain A/J mice, suggesting that stable BPQ-covalent adducts are not a part of the complex of mechanisms involved in B[a]P-induced mouse lung tumorigenesis.

The concentrations of eight heavy metals(Pb, Cd, Cu, Zn, Cr, Ni, Hg and As) from surface sediments of Changshouhu were analyzed. The results showed that the surface sediments of Changshouhu were polluted mainly by Cd, Hg and As compared with the Environmental quality standard for soils, and the intensity of heavy metals pollution of middle area was higher than that of eastern and western area. According to the correlation analysis of various heavy metals, there was a remarkable correlation between Cu, Ni and Zn, which suggested they might have the same origin. Based on the potential ecological risk assessment results, the surface sediments of Changshouhu had reached a low ecological risk level, and the degree of ecological risk of different heavy metals in surface sediments in descending order was Hg>Cd>As>Pb>Ni>Cu>Cr>Zn. Ecological risk index presented by Hakanson to assess the potential ecological risk of Changshouhu was utilized, and some countermeasures for controlling of heavy metals pollution were set forth. Aim of this study is to pretend and control heavy metals pollution of Changshouhu.

In this study, we evaluated the effects of various reaction environments on the adsorption-mediated dechlorination of 2-chlorobiphenyl (2-ClBP) in the RAC system. The results were discussed in close connection to the implementation issue of the RAC system for the remediation of contaminated sites with PCBs. Adsorption event of 2-ClBP onto RAC limited the overall performance under condition with a 2-ClBP/RAC mass ratio of less than 1.0x10 super(4) above which dechlorination of 2-ClBP adsorbed to RAC was the reaction rate-determining step. Acidic and basic conditions were harmful to 2-ClBP adsorption and iron stability while neutral pH showed the highest adsorption-promoted dechlorination of 2-ClBP and negligible metal leaching. Coexisting natural organic matter (NOM) slightly inhibited 2-ClBP adsorption onto RAC due to the partial partitioning of 2-ClBP into NOM in the liquid phase while the 2-ClBP absorbed into NOM, which also tended to adsorb onto RAC, was less available for the dechlorination reaction. Common anions slowed down 2-ClBP adsorption but adsorbed 2-ClBP was almost simultaneously dechlorinated. Some exceptions included strong inhibitory effect of carbonate species on 2-ClBP adsorption and severe detrimental effect of sulfite on 2-ClBP dechlorination. Results on treatment of 2-ClBP spiked to actual sediment supernatants implied site-specific reactivity of RAC.

With increasing organic carbon content and no effort to equilibrate internal standards with the matrix, results are less likely to be accurate. Adding internal standards to soils prior to diluting the sample with water gives more accurate determinations but less reliable quality control (QC). Extending times for equilibration of internal standards improves accuracy but is conducive to analyte degradation not normally observed during analyses. Soil-matrix effects on a given analyte can be greatly understated using a single internal standard as described in Method 8260C while the use of multiple internal standards as described in Method 8261A is more accurate. Method 8261A's reporting error when spiking soils before adding water provides confidence intervals with accuracy near the experimental rule (75.2, 95.7 and 99.5%) with the exception of two analytes that require overnight equilibration.

AN - 733553831; 20363515 AB - Interpretation of toxicogenomic experiments conducted with ovary tissue from asynchronous-spawning small fish species is complicated by background variation in the relative abundance and proportion of follicles at different stages within the ovary tissue sample. This study employed both real-time quantitative polymerase chain reaction and a 15,000 gene oligonucleotide microarray to examine variation in the fathead minnow (Pimephales promelas) ovarian transcriptional profile as a function of quantitative and qualitative differences in ovarian histology. The objectives were to provide data that could potentially aid interpretation of future toxicogenomics experiments, identify putative stage-related transcriptional markers, and generate insights into basic biological regulation of asynchronous oocyte development. Multiple lines of evidence from the present study indicate that variation in the transcriptional profile is primarily dependent on the relative abundance of previtellogenic versus vitellogenic follicles in the ovary. Due to the relatively small proportions of mature ovulated follicles or atretic follicles in the overall follicle population, few potential transcriptional markers of maturation, ovulation, or atresia could be identified. However, among the 460 differentially expressed genes identified in the present study, several targets, including HtrA serine peptidase 3 (htra3), tissue inhibitor of metalloproteinase 3 (timp3), aquaporin 8 (aqp8), transgelin 2 like (tagln2), Nedd4 family interacting protein 2 (ndfip2), chemokine ligand 12a (cxcl12a), midkine-related growth factor (mdka), and jagged 1b (jag 1b) exhibited responses and functional properties that support them as candidate molecular markers of significant shift in gross ovarian stage. Genes associated with a diversity of functions including cellular development, morphogenesis, coated vesicle transport, sexual reproduction, and neuron development, among others, were statistically enriched within the list of 460 genes differentially expressed among different ovarian classes. Overall, results of this study provide insights into background variation in ovary transcript profiles that should aid and enhance the interpretation of toxicogenomic data generated in experiments conducted with small, asynchronous-spawning fish species.

13709898 AB - When a large number of alleles are lost from a population, increases in individual homozygosity may reduce individual fitness through inbreeding depression. Modest losses of allelic diversity may also negatively impact long-term population viability by reducing the capacity of populations to adapt to altered environments. However, it is not clear how much genetic diversity within populations may be lost before populations are put at significant risk. Development of tools to evaluate this relationship would be a valuable contribution to conservation biology. To address these issues, we have created an experimental system that uses laboratory populations of an estuarine crustacean, Americamysis bahia with experimentally manipulated levels of genetic diversity. We created replicate cultures with five distinct levels of genetic diversity and monitored them for 16 weeks in both permissive (ambient seawater) and stressful conditions (diluted seawater). The relationship between molecular genetic diversity at presumptive neutral loci and population vulnerability was assessed by AFLP analysis. Populations with very low genetic diversity demonstrated reduced fitness relative to high diversity populations even under permissive conditions. Population performance decreased in the stressful environment for all levels of genetic diversity relative to performance in the permissive environment. Twenty percent of the lowest diversity populations went extinct before the end of the study in permissive conditions, whereas 73% of the low diversity lines went extinct in the stressful environment. All high genetic diversity populations persisted for the duration of the study, although population sizes and reproduction were reduced under stressful environmental conditions. Levels of fitness varied more among replicate low diversity populations than among replicate populations with high genetic diversity. There was a significant correlation between AFLP diversity and population fitness overall; however, AFLP markers performed poorly at detecting modest but consequential losses of genetic diversity. High diversity lines in the stressful environment showed some evidence of relative improvement as the experiment progressed while the low diversity lines did not. The combined effects of reduced average fitness and increased variability contributed to increased extinction rates for very low diversity populations. More modest losses of genetic diversity resulted in measurable decreases in population fitness; AFLP markers did not always detect these losses. However when AFLP markers indicated lost genetic diversity, these losses were associated with reduced population fitness.

Laboratory tests were conducted in an attempt to volatilize or mobilize contaminants of concern (selected polycyclic aromatic hydrocarbons [PAHs]) from the contaminated sediment into a phase that could be physically removed. The processes were operated above ambient temperature and pressure in an attempt to increase the removal of the contaminants of concern from the sediment. The ability of both the steam injection process and the steam/surfactant process to remove PAHs from the sediment was considered ineffective; as only two of the seventeen selected PAHs (naphthalene and C1 naphthalene) were associated with a percentage mass reduction greater than 34% for both treatments (four trials). The steam/surfactant injection process generally resulted in higher reductions than the steam injection process, but had larger variances within the two trials using the treatment type. This preliminary evaluation suggests that steam-based injection processes for removing petroleum contamination from this canal sediment, using the surfactants selected, equipment set-up, and operating conditions studied, would be considered ineffective.

First morning void (FMV) and spot urine samples from 131 participants in southeastern Michigan were analyzed using an HPLC-IC-PMS system for six different arsenic species: arsenobetaine (AsB), arsenite (As[III]), arsenate (As[V]), methylarsonous acid MMA[III], methylarsenic acid MMA[V], and dimethylarsenic DMA[V]. Bland-Altman plots, intraclass correlation coefficients (ICCs), and Pearson correlation procedures were used to evaluate the relationship between the arsenic species in FMV and spot urine collections after normalizing the samples by specific gravity. DMA[III] and MMA[III] were not detected in any of the samples. The sum of As[III], As[V], MMA[V], and DMA[V] was designated SumAs. The ICC between SumAs in FMV and SumAs in spot samples was 0.90. The ICC showed that 90% of variation comes from between individuals and not within individuals. A significant correlation (r = 0.80 p 0.001) was observed between FMV and spot samples for SumAs. The spot sample were a good predictor of the MMA[V] (r = 0.83 p 0.0001), and DMA[V] (r = 0.77 p 0.0001) in the FMV sample. These associations suggest that either FMV or spot samples can be used as an adequate bioindicator of arsenic metabolites in human urine. The benefit of using spot urine samples, instead of 24-h or FMV urine samples, is the potential reduction in budgetary and logistic requirements in epidemiological studies.

This study integrates He isotope data with radiogenic isotope data (Sr-Nd-Pb-Hf), stable isotope data (delta (super 18) O), and trace element data to characterize the compositional features of the trace element enriched components of the Icelandic mantle. We also present high-precision Pb isotope data on an additional 57 lava samples from the flank zones (including Oeraefajoekull in the SE) and the Northern and Eastern rift zones. Most Icelandic lavas have negative (super 207) Pb (-4 to -1), with higher values (-1 to +4) found only in samples from Oeraefajoekull, Snaefell, and parts of the Reykjanes Peninsula. At Snaefell, this EM1-type component is characterized by a low (super 18) O olivine signature (+4.1 ppm to +4.6 ppm), moderate (super 206) Pb/ (super 204) Pb values (18.4-18.6) and mid-ocean ridge basalt (MORB)-like (super 3) He/ (super 4) He (6.9-7.5 R/RA). Samples from Vestmannaeyjar and Snaefellsnes have mantle-like delta (super 18) O (sub olivine) (+4.9 ppm to +5.0 ppm), and radiogenic (super 206) Pb/ (super 204) Pb values (18.9-19.3) that fall on the Northern Hemisphere Reference Line for (super 208) Pb/ (super 204) Pb (Delta (super 208) Pb - 5 to +5). Compared with the Vestmannaeyjar lavas, Snaefellsnes lavas have higher La/YbN (5-11 vs 3-5), lower epsilon (sub Nd) (5.5-6.5 vs 6.8-7.6) and lower (super 3) He/ (super 4) He (6.3-8.6 R/RA vs 11.4-13.5 R/RA). Therefore, the most trace element enriched components in the Icelandic mantle are not the carriers of the high (super 3) He/ (super 4) He values (< R/RA) found in some lavas on Iceland and the adjacent ridges, and instead are consistent with degassed, recycled components. Even after excluding the EM1-type high (super 207) Pb samples, high-precision Pb isotope data produce a kinked array on a (super 206) Pb/ (super 204) Pb vs (super 208) Pb/ (super 204) Pb plot, which is not consistent with simple binary mixing between two end-members. This requires significant lateral heterogeneity within the Icelandic mantle and the presence of more than just two compositionally distinct local mixing end-member components. Samples from each of the main axial rift zones define different trends. Despite the tectonic continuity between the Northern Volcanic Zone and the Eastern Volcanic Zone, lavas from these two rift zones define separate sub-parallel linear arrays. Lavas from the adjacent Western Volcanic Zone and the Eastern Volcanic Zone define oblique linear arrays that converge on a common local end-member that is not involved in the magmatism of the Northern Volcanic Zone. Therefore, there is a distinct NE-SW compositional heterogeneity within the Icelandic mantle.

Prior to this event, the island was a 23-km-long microtidal composite barrier island located in the northern Gulf of Mexico approximately 8.0km offshore from southwestern Alabama (U.S.A.). The eastern portion of Dauphin Island was morphologically a barrier island, and it experienced gulf-facing beach erosion at several isolated hot spots. The western portion of Dauphin Island was an elongated barrier spit with little topographic relief, and it experienced gulf-facing beach erosion and occasional washover due to elevated tides and storm waves. The protection and preservation of the residential property on the barrier-spit portion of the island has been a priority for the incorporated Town of Dauphin Island since the late 1970s. On two separate occasions the Town of Dauphin Island combined funds with those provided by the U.S. Federal Emergency Management Agency and contracted the U.S. Army Corps of Engineers to construct a shore-parallel sand dune. The first dune was built following Hurricane Georges and the second after Hurricane Katrina. Both of these structures were completely eroded away within a short span of time, the post-Hurricane Georges dune in 27 months and the post-Hurricane Katrina dune in 15 months. Despite the high cost, limited effectiveness, and short service life of constructed sand dunes, the remaining options are either unacceptable (e.g., beach armoring, land use reclassification, or abandonment) or too costly (e.g., engineered beach). Constructed shore-parallel sand dunes will likely remain integral to the protection and preservation of the residentially developed, barrier-spit portion of Dauphin Island East due to its low relief and the high probability of washover events from elevated tides and storm waves.

However, no studies have evaluated the effects of the chlorotriazine simazine on pubertal development in the female rat. Here we report the effects of a 21- and 41-day exposure to simazine on pubertal development and estrous cyclicity in the female rat using the U.S. Environmental Protection Agency's Endocrine Disruptor Screening Program, Pubertal Development and Thyroid Function in Intact/Juvenile Peripubertal Female Rats (Tier 1) protocol. In the first study, Wistar rats were exposed orally to 0, 12.5, 25, 50, or 100mg/kg of simazine from postnatal day 22 to 42. In the second study, rats were exposed from PND 22 until the first day of estrus after PND 62 to 0, 12.5, 25, 50, 100 or 200mg/kg of simazine. In the 21-day exposure, vaginal opening (VO) was delayed, the number of normal cycles was significantly decreased, and the day of first estrus was delayed compared to controls. In the 41-day exposure, VO and the day of first estrus was delayed, but the number of normal estrous cycles was not different than controls. In addition, both studies showed a significant decrease in serum prolactin (PRL) following simazine exposure. This data clearly demonstrates that simazine delays the onset of puberty in the female rat and decreases serum PRL similar to other chlorotriazines. The extended dosing period after VO provides a sufficient time period to monitor the effects of a toxicant on estrous cyclicity, an important measure for reproductive competence.

For the analyses involved, we used data from a total of more than 300 microarrays representing 58 conditions, which encompassed 4 tissue types from zebrafish of both genders exposed for 1 of 3 durations to 10 different test chemicals (17 alpha -ethynyl estradiol, fadrozole, 17 beta -trenbolone, fipronil, prochloraz, flutamide, muscimol, ketoconazole, trilostane, and vinclozolin). Differentially expressed genes were identified by one class t-tests for each condition, and those with false discovery rates of less than 40% and treatment/control ratios greater than or equal to 1.3-fold were mapped to orthologous human, mouse, and rat pathways by Ingenuity Pathway Analysis to look for overrepresentation of known biological pathways. To complement the analysis of known biological pathways, the genes regulated by approximately 1800 transcription factors were inferred using the ARACNE mutual information-based algorithm. The resulting gene sets for all transcriptional factors, along with a group of compiled HPG-axis genes and approximately 130 publicly available biological pathways, were analyzed for their responses to the 58 treatment conditions by Gene Set Enrichment Analysis (GSEA) and its variant, Extended-GSEA. The biological pathways and transcription factors associated with multiple distinct treatments showed substantial interactions among the HPG-axis, TGF-beta, p53, and several of their cross-talking partners. These candidate networks/pathways have a variety of profound impacts on such cellular functions as stress response, cell cycle, and apoptosis.

Determination of the sources of PM2.5 most responsible for these health effects could lead to improved understanding of the mechanisms of such effects and more targeted regulation. This has provided the impetus for the Denver Aerosol Sources and Health (DASH) study, a multi-year source apportionment and health effects study relying on detailed inorganic and organic PM2.5 speciation measurements. In this study, PM2.5 source apportionment is performed by coupling positive matrix factorization (PMF) with daily speciated PM2.5 measurements including inorganic ions, elemental carbon (EC) and organic carbon (OC), and organic molecular markers. A qualitative comparison is made between two models, PMF2 and ME2, commonly used for solving the PMF problem. Many previous studies have incorporated chemical mass balance (CMB) for organic molecular marker source apportionment on limited data sets, but the DASH data set is large enough to use multivariate factor analysis techniques such as PMF. Sensitivity of the PMF2 and ME2 models to the selection of speciated PM2.5 components and model input parameters was investigated in depth. A combination of diagnostics was used to select an optimum, 7-factor model using one complete year of daily data with pointwise measurement uncertainties. The factors included 1) a wintertime/methoxyphenol factor, 2) an EC/sterane factor, 3) a nitrate/polycyclic aromatic hydrocarbon (PAH) factor, 4) a summertime/selective aliphatic factor, 5) an n-alkane factor, 6) a middle-oxygenated PAH/alkanoic acid factor and 7) an inorganic ion factor. These seven factors were qualitatively linked with known PM2.5 emission sources with varying degrees of confidence. Mass apportionment using the 7-factor model revealed the contribution of each factor to the mass of OC, EC, nitrate and sulfate. On an annual basis, the majority of OC and EC mass was associated with the summertime/selective aliphatic factor and the EC/sterane factor, respectively, while nitrate and sulfate mass were both dominated by the inorganic ion factor. This apportionment was found to vary substantially by season. Several of the factors identified in this study agree well with similar assessments conducted in St. Louis, MO and Pittsburgh, PA using PMF and organic molecular markers.

Molecular methods, such as the reverse transcriptase PCR (RT-PCR), can detect viral genomes in a few hours, but they cannot distinguish between infectious and noninfectious viruses. Since only infectious viruses are a public health concern, methods that not only are rapid but also provide information on the infectivity of viruses are of interest. The intercalating dye propidium monoazide (PMA) has been used for distinguishing between viable and nonviable bacteria with DNA genomes, but it has not been used to distinguish between infectious and noninfectious enteric viruses with RNA genomes. In this study, PMA in conjunction with RT-PCR (PMA-RT-PCR) was used to determine the infectivity of enteric RNA viruses in water. Coxsackievirus, poliovirus, echovirus, and Norwalk virus were rendered noninfectious or inactivated by treatment with heat (72C, 37C, and 19C) or hypochlorite. Infectious or native and noninfectious or inactivated viruses were treated with PMA. This was followed by RNA extraction and RT-PCR or quantitative RT-PCR (qRT-PCR) analysis. The PMA-RT-PCR results indicated that PMA treatment did not interfere with detection of infectious or native viruses but prevented detection of noninfectious or inactivated viruses that were rendered noninfectious or inactivated by treatment at 72C and 37C and by hypochlorite treatment. However, PMA-RT-PCR was unable to prevent detection of enteroviruses that were rendered noninfectious by treatment at 19C. After PMA treatment poliovirus that was rendered noninfectious by treatment at 37C was undetectable by qRT-PCR, but PMA treatment did not affect detection of Norwalk virus. PMA-RT-PCR was also shown to be effective for detecting infectious poliovirus in the presence of noninfectious virus and in an environmental matrix. We concluded that PMA can be used to differentiate between potentially infectious and noninfectious viruses under the conditions defined above.

Lack of confidence in the risk assessment process (as the basis for a risk management decision), beginning with evaluation of raw data and continuing through the risk decision process, is largely because of issues surrounding transparency. There is a critical need to implement greater transparency throughout the risk assessment process, and although doing so will not guarantee the correctness of the risk assessment or that all risk assessors come up with the same conclusions, it will provide essential information on how a particular conclusion or decision was made, thereby increasing confidence in the conclusions. Recognizing this issue, the International Life Sciences Institute Health and Environmental Sciences Institute convened a multisector committee tasked with discussing this issue and examining existing guidance and recommendations related to transparency in risk assessment. The committee concluded that transparency is inextricably linked to credibility: credibility of the data, credibility of the risk assessment process, and credibility of the resulting decision making. To increase this credibility, existing guidance concerning criteria elements of transparency related to the risk assessment process must be more widely disseminated and applied, and raw data for studies used in human health and environmental risk assessment must be more widely available. Finally, the decision-making process in risk management must be better documented and a guidance framework established for both the process itself and its communication to the public.

Interactions between aboveground C and N cycling are more clearly characterized than belowground processes. Through synthesizing data from multiple terrestrial ecosystems, we quantified the responses of belowground C cycling under N addition. We found that N addition increased litter input from aboveground (+20%) but not from fine root. N addition inhibited microbial activity as indicated by a reduction in microbial respiration (-8%) and microbial biomass carbon (-20%). Although soil respiration was not altered by N addition, dissolved organic carbon concentration was increased by 18%, suggesting C leaching loss may increase. N addition increased the C content of the organic layer (+17%) but not the mineral soil layer. Overall, our meta-analysis indicates that N addition will increase short term belowground C storage by increasing C content of organic layer. However, it is difficult to predict the response of long term C sequestration since there is no significant change in mineral soil C content.

Variation among killifish populations was characterized in 28-day laboratory challenges using embryonic and larval life stages and the highly toxic, dioxin-like PCB congener, 3,3'4,4',5-hexachlorobiphenyl (PCB126). In summarizing results for 24 populations, we show that killifish populations vary over four orders of magnitude in their sensitivity to PCB126 and that this variation is adaptive to the magnitude of contamination at their residence site. The four least-sensitive killifish populations reside in US Atlantic coast urban harbors >100km apart from one another: New Bedford, MA, Bridgeport, CT, Newark, NJ, and Norfolk, VA, USA. Prior studies examining all but the CT population have shown that these killifish are relatively insensitive to local contaminants, with mixed evidence concerning the heritability of this trait. We show here that tolerance to PCB126 is extreme, with some mechanistic similarities among these four killifish populations. However, these populations do not respond identically to each other, and in at least one population, tolerance appears to degrade over the F1 and F2 generations tested. Complementary ongoing studies using molecular approaches provide opportunity to identify unique and shared mechanisms of tolerance in these independently evolving populations and explore the adaptive benefits and costs of contemporary evolutionary responses in the wild.

Tests were also conducted in a dry heat oven to determine the destruction kinetics for the same species. In the pilot-scale incinerator tests, B. atrophaeus and G. stearothermophilus demonstrated similar thermal sensitivity, but B. anthracis (Sterne) was less thermally resistant than G. stearothermophilus. For the dry heat oven tests conducted at 175C, the D-values were 0.4, 0.2 and 0.3 min for B. atrophaeus, B. anthracis (Sterne) and G. stearothermophilus, respectively.Conclusions: Bacillus anthracis (Sterne) possesses similar or less dry heat resistance compared to B. atrophaeus and G. stearothermophilus.Significance and Impact of the Study: Previous studies have demonstrated conditions under which bacterial spores may survive in an incinerator environment. The data from this study may assist in the selection of surrogates or indicator micro-organisms to ensure B. anthracis spores embedded in building materials are completely inactivated in an incinerator.

The use of species traits to interpret biological changes in invertebrate assemblages across environmental gradients has been suggested as a method to improve discrimination over existing species composition methods. One reason for greater potential discrimination and predictive ability is the assumed universality of traits across a range of spatial and temporal scales. We explore this assumption by comparing the consistency of stressor-response relationships of a trait characteristic (percent clinging taxa) and a common taxonomy-based metric [percent Ephemeroptera, Plecoptera and Trichoptera (EPT)] over a stressor gradient of increasing benthic fine sediment.2. We use invertebrate assemblage and environmental data from three large-scale surveys that cover the western United States, eastern United States and the Mid-Atlantic Highlands of the US. These three datasets allow us to compare stressor-response relationships in terms of geographic position (west versus east) and spatial scale (entire east versus a sub-region of the east). We compare the slopes and intercepts of the two measures of assemblage response.3. Trait characteristics exhibited more consistent stressor-response relationships than identity characteristics. Stressor-response relationships generated for clinging invertebrate richness had statistically similar slopes over sediment gradients, regardless of spatial scale or geographic location. In contrast, slopes were significantly different for relationships generated with EPT richness over sediment gradients.4. Results of this study support the hypothesis that trait-based measures have a more consistent response to a stressor gradient than identity-based assemblage measures. Choosing consistent measures of community response will facilitate comparisons among assemblages across large spatial scales.

AN - 733307619; 20375078 AB - Developmental effects of polybrominated diphenyl ethers (PBDEs) have been suspected due to their structural similarities to polychlorinated biphenyls (PCBs). This study evaluated neurobehavioral, hormonal, and reproductive effects in rat offspring perinatally exposed to a widely used pentabrominated commercial mixture, DE-71. Pregnant Long-Evans rats were exposed to 0, 1.7, 10.2, or 30.6 mg/kg/day DE-71 in corn oil by oral gavage from gestational day 6 to weaning. DE-71 did not alter maternal or male offspring body weights. However, female offspring were smaller compared with controls from postnatal days (PNDs) 35-60. Although several neurobehavioral endpoints were assessed, the only statistically significant behavioral finding was a dose-by-age interaction in the number of rears in an open-field test. Developmental exposure to DE-71 caused severe hypothyroxinemia in the dams and early postnatal offspring. DE-71 also affected anogenital distance and preputial separation in male pups. Body weight gain over time, reproductive tissue weights, and serum testosterone concentrations at PND 60 were not altered. Mammary gland development of female offspring was significantly affected at PND 21. Congener-specific analysis of PBDEs indicated accumulation in all tissues examined. Highest PBDE concentrations were found in fat including milk, whereas blood had the lowest concentrations on a wet weight basis. PBDE concentrations were comparable among various brain regions. Thus, perinatal exposure to DE-71 leads to accumulation of PBDE congeners in various tissues crossing blood-placenta and blood-brain barriers, causing subtle changes in some parameters of neurobehavior and dramatic changes in circulating thyroid hormone levels, as well as changes in both male and female reproductive endpoints. Some of these effects are similar to those seen with PCBs, and the persistence of these changes requires further investigation.

AN - 733298092; 20398685 AB - Dermal exposure to pyrethroid pesticides can occur during manufacture and application. This study examined the in vitro dermal absorption of pyrethroids using rat and human skin. Dermatomed skin from adult male Long Evans rats or human cadavers was mounted in flow-through diffusion cells, and radiolabeled bifenthrin, deltamethrin or cis-permethrin was applied in acetone to the skin. Fractions of receptor fluid were collected every 4h. At 24h, the skins were washed with soap and water to remove unabsorbed chemical. The skin was then solubilized. Two additional experiments were performed after washing the skin; the first was tape-stripping the skin and the second was the collection of receptor fluid for an additional 24 h. Receptor fluid, skin washes, tape strips and skin were analyzed for radioactivity. For rat skin, the wash removed 53-71% of the dose and 26-43% remained in the skin. The cumulative percentage of the dose at 24 h in the receptor fluid ranged from 1 to 5%. For human skin, the wash removed 71-83% of the dose and 14-25% remained in the skin. The cumulative percentage of the dose at 24 h in the receptor fluid was 1-2%. Tape-stripping removed 50-56% and 79-95% of the dose in rat and human skin, respectively, after the wash. From 24-48 h, 1-3% and about 1% of the dose diffused into the receptor fluid of rat and human skin, respectively. The pyrethroids bifenthrin, deltamethrin and cis-permethrin penetrated rat and human skin following dermal application in vitro. However, a skin wash removed 50% or more of the dose from rat and human skin. Rat skin was more permeable to the pyrethroids than human skin. Of the dose in skin, 50% or more was removed by tape-stripping, suggesting that permeation of pyrethroids into viable tissue could be impeded. The percentage of the dose absorbed into the receptor fluid was considerably less than the dose in rat and human skin. Therefore, consideration of the skin type used and fractions analyzed are important when using in vitro dermal absorption data for risk assessment. Published by Elsevier Inc.

Posthurricane conditions were compared to prehurricane (2000-2004) conditions, for sediment quality data. There were no exceedances of effects range median (ERM) sediment quality guideline values for chemical contaminants in any of the sediment samples collected from the Lake Pontchartrain or the Mississippi Sound study areas following the hurricane. Lower threshold effects range low (ERL) values were exceeded for As, Cd, and Ni at several stations in both survey areas, similar to levels of contamination observed prior to the hurricane. The comparison of sediment quality indicators before and after the hurricane suggests considerable stability of these systems with respect to short-term ecological impacts. Although other studies have shown storm-related changes could be detected (e.g., effects on benthic communities associated with shifts in salinity), there were no indications of widespread sediment contamination.

In this study, different concentrations of TiO2 nanoparticles were suspended in cell culture medium. The suspension was then sonicated and characterized by dynamic light scattering and microscopy. Cultured human-derived retinal pigment epithelial cells (ARPE-19) were incubated with TiO2 nanoparticles at ,0.,0.3, 1, 3, 10, and 30 Delta *mg/ml for 24 hours. Cellular reactions to nanoparticles were evaluated using flow cytometry and dark field microscopy. A FACSCalibur Delta TM flow cytometer was used to measure changes in light scatter after nanoparticle incubation. Both the side scatter and forward scatter changed substantially in response to the TiO2. From 0.1 to 30 Delta *mg/ml TiO2, the side scatter increased sequentially while the forward scatter decreased, presumably due to substantial light reflection by the TiO2 particles. Based on the parameters of morphology and the calcein-AM/propidium iodide viability assay, TiO2 concentrations below 30 Delta *mg/ml TiO2 caused minimal cytotoxicity. Microscopic analysis was done on the same cells using an E-800 Nikon microscope containing a xenon light source and special dark field objectives. At the lowest concentrations of TiO2 (0.1-0.3 Delta *mg/ml), the flow cytometer could detect as few as 5-10 nanoparticles per cell due to intense light scattering by TiO2. Rings of concentrated nanoparticles were observed around the nuclei in the vicinity of the endoplasmic reticulum at higher concentrations. These data suggest that the uptake of nanoparticles within cells can be monitored with flow cytometry and confirmed by dark field microscopy. This approach may help fulfill a critical need for the scientific community to assess the relationship between nanoparticle dose and cellular toxicity Such experiments could potentially be performed more quickly and easily using the flow cytometer to measure both nanoparticle uptake and cellular health.

16194465 AB - The U.S. Environmental Protection Agency (EPA) in partnership with the National Council on Skin Cancer Prevention requests a session entitled "Sun Safety and Preventing Skin Cancer: How broadcast meteorologists can use Social Media to Educate the Public". The explosion of social media - Facebook, Twitter, and Smartphones - is creating new ways for people to get weather information. EPA is using the UV Index as an entry point into social media for its sun safety efforts. By providing easy access to a discrete number, which in turn is tied to actionable steps, the sun safety message is reaching new audiences. As broadcast meteorologists continue to use more multimedia during their weather forecasts, providing weather information via social media provides opportunities to stay connected to existing audiences and also reach new audiences. The themes of the session will be: -An overview of stratospheric ozone layer depletion and its connection to public health; -Highlights of the social media campaign; -Enhancements to the UV Index forecast (hourly data, XML feed); and -Highlights from another sun safety initiative, Don't Fry Day 2010 Background: EPA is involved in skin cancer prevention and sun safety education through its stratospheric ozone protection program and SunWise program. As broadcast meteorologists know, the ozone layer forms a thin shield in the upper atmosphere, protecting life on Earth from the sun's ultraviolet (UV) rays. Sustained depletion of the ozone layer results in increased UV radiation reaching the Earth's surface. Overexposure to UV radiation can in turn lead to serious health effects, such as skin cancer, cataracts, and immune suppression. JF - American Meteorological Society. [np]. 23 Jun 2010.

16194931 AB - Recent simulations of the eastern United States using the Community Multiscale Air Quality (CMAQ) modeling system identified the summer of 2005 as a period of poor model performance for fine particulate sulfate (SO42-). The meteorological conditions during this time period included hot and dry conditions in the upper Midwest, an extreme heat wave in the southwestern U.S., and a high frequency of tropical cyclones affecting the southeastern U.S. The primary pathways for SO42- formation in the atmosphere include the gas-phase reaction of SO2 with OH, and aqueous oxidation of S(IV) to S(VI) in cloud water. An investigation using the CMAQ sulfur tracking model for this time period estimates that the aqueous pathway accounted for ~50% of the SO42- in the upper Mississippi Valley and ~75% in the southeastern U.S; the gas-phase reaction accounts for the other SO42- production. Because clouds play such an important role in the formation of SO42- (both directly by providing the cloud water for aqueous oxidation and indirectly by attenuating the solar radiation that drives the photochemistry and OH concentrations), errors in cloud cover may be affecting the model's performance during this period. The 5th Generation Mesoscale Model (MM5) and now more recently the Weather Research and Forecasting (WRF) model include the capability of assimilating satellite-derived clouds to improve the performance of model predictions. In addition, CMAQv4.7 includes an option to use satellite-derived cloud products to calculate photolysis rates. This study will investigate the impacts of using satellite-derived products on SO42- model performance. The period of July 2005 will be simulated using two different CMAQ model configurations, one utilizing model-derived photolysis rate estimates and the other utilizing the satellite-derived estimates. The SO42- predictions from each simulation will be compared to available surface observations and the performance of each simulation assessed. This work has direct implications for many retrospective air quality simulation applications, including federal rule-making and to State Implementation Plan (SIP) development.

To investigate the in utero effects of DE exposure, timed pregnant BALB/c mice were exposed to 0, 0.8 or 3.1mg/m super(3) of DE during gestation days (GD) 9 to GD 18. The number of successful pregnancies was 15/20 in the air controls and 10/20 in each of the diesel exposures. Immune function in the 6-week-old offspring as determined by development of delayed type hypersensitivity (DTH) reactions to bovine serum albumin (BSA), antibody titers to injected sheep red blood cells (SRBC), splenic T cells expressing CD45 super(+)CD3 super(+)CD8 super(+) and CD3 super(+)CD25 super(+), and mRNA expression of TNF- alpha , TLR2, SP-A, TGF- beta and Foxp3 in the lung were not affected by prenatal DE exposure. On the other hand, lung TLR4 mRNA expression, the number of neutrophils in the bronchoalveolar lavage fluid (BALF) and splenic T cells expressing CD45 super(+)CD3 super(+)CD4 super(+) and CD4 super(+)CD25 super(+) were differentially affected depending on the DE concentration and gender. When additional groups of mice were sensitized and challenged via the respiratory tract with ovalbumin to induce allergic airway inflammation, female mice had higher protein levels in the BALF compared to males and this was reduced by prenatal exposure to either concentration of DE. No other changes in allergen-induced immunity, lung function or severity of inflammation were noted. Collectively, the results show that in utero exposure to DE altered some baseline inflammatory indices in the lung in a gender-specific manner, but had no effect on development of specific immune responses to experimental antigens, or the severity of allergic lung inflammation.

Our objective was to determine how a plant community responds over several generations to elevated ozone exposures. Seed bank soil collected from the Oregon State University Farm, containing a population of naturalized plants common to the Willamette Valley, was uniformly dispersed across the surface of nine modified open top chambers. Each chamber was randomly assigned one of three ozone treatments (0, 90 and 120ppb episodic ozone). Sixty plant species from 22 families emerged in the chambers over the four year study. Seedling emergence was a highly sensitive period. High seedling mortality rates in the ozone treatments allowed more resistant individuals to persist. Communities not exposed to elevated ozone levels also had high rates of mortality probably due to density dependant mortality. No species were eliminated from the communities because of ozone. Plant species did not demonstrate ozone tolerance or susceptibility based on taxonomic relationships. Year-to-year environmental heterogeneity was a stronger influence on community composition than ozone exposures. At the community level, there was a trend of decreasing biomass with increasing ozone exposure. In the ozone treatments, premature senescence of taller species increased light availability to understory species, changing competitive interactions and altering community dynamics in the understory. The effects of ozone on individual species, both direct and indirect, in a community may be detrimental, insignificant, or positive. Predication of a species performance in a community will be difficult due to the many environmental and biological interactions occurring simultaneously or at alternative times during a specific species life cycle. Studies are necessary to decrease the uncertainty in attempting to assess the impact of ozone on both managed and natural ecosystems currently determined from extrapolating the effects on individuals. Currently, plant communities remain protected at an unknown level from ozone exposure.

Nationwide, NLCD 2001 overall Anderson Level II and Level I accuracies were 78.7% and 85.3%, respectively. By comparison, overall accuracies at Level II and Level I for the NLCD 1992 were 58% and 80%. Forest and cropland were two classes showing substantial improvements in accuracy in NLCD 2001 relative to NLCD 1992. NLCD 2001 forest and cropland user's accuracies were 87% and 82%, respectively, compared to 80% and 43% for NLCD 1992. Accuracy results are reported for 10 geographic regions of the United States, with regional overall accuracies ranging from 68% to 86% for Level II and from 79% to 91% at Level I. Geographic variation in class-specific accuracy was strongly associated with the phenomenon that regionally more abundant land-cover classes had higher accuracy. Accuracy estimates based on several definitions of agreement are reported to provide an indication of the potential impact of reference data error on accuracy. Drawing on our experience from two NLCD national accuracy assessments, we discuss the use of designs incorporating auxiliary data to more seamlessly quantify reference data quality as a means to further advance thematic map accuracy assessment.

Large-volume water sampling (up to 100 L) was employed because it was anticipated that pesticide contamination, if present, would be at very low levels. The target compounds comprise pesticides (and selected oxygen transformation products) known to have been extensively used in agriculture in the San Joaquin Valley, CA, USA. Solid phase extraction using the polymeric resin Abselut Nexus was optimized to extract the pesticide analytes from water samples. A single determinative method using GC-MS with electron ionization was used for all the analytes. Recoveries from 100 L of reagent water at 100 pg/L and 1 ng/L concentrations were generally greater than 75%, although dimethoate, disulfoton, and phorate were not recovered. Analysis of the extracts without cleanup yielded detection limits for the remaining 38 analytes between 0.1 and 30 ng/L. A silica cleanup with separate analysis of 3 eluant fractions improved detection limits for 37 of the compounds to between 6 and 600 pg/L in high-elevation surface waters.

Previous work demonstrated increases in the expression of Ca2+/calmodulin-dependent protein kinase 1-gamma (Camk1g) mRNA following acute deltamethrin and permethrin exposure. In the rat, this gene is expressed as two distinct splice variants, Camk1g1 and Camk1g2. The present study tests the hypothesis that changes in Camk1g mRNA expression in the rat following acute pyrethroid exposure are due to a specific increase in the Camk1g1 splice variant and not the Camk1g2 splice variant. Long-Evans rats were acutely exposed to permethrin, deltamethrin, or corn oil vehicle. Frontal cortex was collected at 6 h postdosing. In addition, rats were exposed to permethrin (100 mg/kg) or deltamethrin (3 mg/kg), and frontal cortex was collected at 1, 3, 6, 9, 12, or 24 h along with time-matched vehicle controls. Expression of Camk1g1 and Camk1g2 mRNA was measured by quantitative real-time RT-PCR and quantified using the 2- Delta *D Delta *D CT method. Dose-dependent increases in Camk1g1 mRNA expression were observed for both pyrethroids at 6 h. In addition, a dose-dependent increase in Camk1g2 was observed at 6 h although it was very small in magnitude. The increases in Camk1g1 expression for deltamethrin and permethrin peak between 3 and 6 h postexposure and returns to control levels by 9 h. There was no increase in CAMK1G1 protein as measured with Western blots. The present data demonstrate that pyrethroid-induced changes in Camk1g are driven mainly by increased expression of the Camk1g1 splice variant. [copy 2010 Wiley Periodicals, Inc.

For the last 20years, however, the scientific community has paid great attention to alternative strategies in compliance with common moral and ethical values. The new European chemical regulation REACH (Reg. EC 1907/2006) requires the performance of new studies in vertebrates only as a last resort. REACH asks for the development of validated in vitro protocols that can replace, in the medium to the long term, animal bioassays. An in vitro cell transformation assay (CTA) is proposed as an alternative to in vivo carcinogenicity testing. This assay is reported in the list of accepted methods for REACH (Reg. EC 440/2008). The BALB/c 3T3 model represents one of the most well-known CTAs and is regarded as a useful tool to screen single chemicals or complex mixtures for carcinogenicity prediction. In this study we used a modified protocol to highlight the transforming potential of three single compounds, ethinylestradiol (EE), azathioprine (AZA-T), melphalan, and two polychlorinated biphenyls (PCBs) mixtures, which are known or suspected to be human carcinogens. We also evaluated the activity of the antioxidant alpha-lipoic acid (ALA), a promising tumor chemopreventive. A significant increase in transformation frequency was observed when the BALB/c 3T3 cells were exposed to EE, AZA-T or melphalan as well as after PCBs treatment. On the contrary, ALA did not induce any increase of foci occurrence. Our results confirm the suitability of the improved protocol to discriminate carcinogenic compounds and support the use of BALB/c 3T3 cell transformation assay as a possible alternative to predict carcinogenic risk to humans.

It is important to understand the potential interactive effects of these mixtures to properly assess their risk. Estrogen receptor agonists exhibit additivity in mixtures when tested in vivo and in vitro. Little is known, however, concerning possible mixture interactions of androgen receptor agonists. In these studies we used the MDA-kb2 cell line, a human breast cancer cell line with endogenous androgen receptors and a stably transfected luciferase reporter gene construct to quantify the androgenic activity of seven natural and synthetic androgens: 17 beta -trenbolone, dihydrotestosterone, methyltestosterone, testosterone, trendione, 17-trenbolone, and androstenedione. We tested combinations of these androgens and compared the observed activity to expected androgenic activity based on a concentration addition model. Our analyses support the hypothesis that androgen receptor agonists cause additive responses in a mixture. Binary mixtures of 17 beta -trenbolone with 17 beta -estradiol or triclocarban (an anti-microbial found in the environment) were also tested. 17 beta -Estradiol induced androgenic activity, but only at concentrations 600-fold greater than those found in the environment. Triclocarban enhanced the activity of 17 beta -trenbolone. Additionally, three anti-androgens were each paired with three androgens of varying potencies. The relative potencies of the antagonists were a vinclozolin metabolite (M2) > procymidone > prochloraz regardless of the androgen used. The results of our studies demonstrate the potential utility of the androgen-responsive MDA-kb2 cell line for quantifying the activity of mixtures of endocrine-active chemicals in complex wastes such as municipal effluents and feedlot discharges.

Methods used to determine oocyst infectivity have relied primarily on mouse, chicken, and feline bioassays. Although considered gold standards, they only provide a qualitative assessment of oocyst viability. In this study, two alternative approaches were developed to quantitate viable T. gondii oocysts following treatment with several common sanitizers. The first is a quantitative reverse transcriptase real-time PCR (RT-qPCR) assay targeting the ACT1 and SporoSAG genes to enumerate viable T. gondii oocysts. RT-qPCR C T values between WescodyneA+, acidified ethanol, or heat treated oocysts were not significantly different as compared with untreated controls. By contrast, treatment with formalin or CloroxA+ resulted in a 2-log10 reduction in C T values. An in vitro T. gondii oocyst plaque assay (TOP-assay) was also developed to measure oocyst viability. This assay used a combination of bead milling and bile digestion, followed by culturing the excysted sporozoites in a confluent fibroblast cell monolayer. Results showed that no significant reduction in sporozoite viability was detected in acidified ethanol or WescodyneA+ treated oocysts while at least a 2-log10 reduction in plaques formed was observed with CloroxA+ treated oocysts. Moreover, formalin or heat treatment of oocysts resulted in at least a 5-log10 reduction in plaques formed. This study demonstrates that an mRNA-based PCR viability assay targeting the ACT1 or SporoSAG genes is a relatively rapid technique compared to in vitro and in vivo assays.

Ground-based measurements were made primarily at 30aam behind the engine for PM mass and number concentration, particle size distribution, and total volatile matter using both time-integrated and continuous sampling techniques. The experimental results showed a PM mass emission index (EI) ranging from 10 to 550aamgaakga1 fuel depending on engine type and test parameters as well as a characteristic U-shaped curve of the mass EI with increasing fuel flow for the turbofan engines tested. Also, the Teflon filter sampling indicated that a1440-80% of the total PM mass on a test-average basis was comprised of volatile matter (sulfur and organics) for most engines sampled. The number EIs, on the other hand, varied from a141015 to 1017 particles kga1 fuel with the turbofan engines exhibiting a logarithmic decay with increasing fuel flow. Finally, the particle size distributions of the emissions exhibited a single primary mode that were lognormally distributed with a minor accumulation mode also observed at higher powers for all engines tested. The geometric (number) mean particle diameter ranged from 9.4 to 37aanm and the geometric standard deviation ranged from 1.3 to 2.3 depending on engine type, fuel flow, and test conditions.

In some cases, these affected individuals are completely sex reversed and are morphologically indistinguishable from normal individuals of the opposite sex. Detecting shifts in sex ratios following chemical exposure often requires large numbers of organisms to achieve the necessary statistical power, especially in those species with genetic sex determination and homomorphic sex chromosomes (such as amphibians and many fish). The ability to assess the genetic sex of individuals would allow for detection of sex reversal (genotype-phenotype mismatches) that have greater statistical power compared to examining changes in sex ratios. Utilizing amplified fragment length polymorphisms (AFLPs), we developed a method for genotyping sex in the amphibian, Xenopus (Silurana) tropicalis, that can be incorporated into endocrine disruptor screening assays that examine the effects of chemicals on gonad differentiation. AFLPs from 512 primer pairs were assessed in one spawn of X. tropicalis. Each primer pair yielded, on average, 100 fragments. In total 17 sex-linked AFLPs were identified, isolated, and sequenced. A recombination map of these AFLPs was generated using over 300 individuals with four AFLPs having a recombination rate of 0% with regard to sex. A BLASTn search of the X. tropicalis genome using these AFLP sequences resulted in identification of sex-linked scaffolds. Areas of these scaffolds were searched for additional polymorphisms that could be utilized for genotyping sex. Retrospective and prospective strategies for incorporating genotyping sex in endocrine disruptor bioassays with X. tropicalis were developed. A Monte Carlo simulation comparing analyzing data as sex ratio shifts versus assessment of sex reversal using genotyping demonstrates the increase in statistical power that can be obtained by genotyping sex in studies dealing with altered gonad differentiation. This approach to identifying sex-linked markers and developing sex genotyping methods is applicable to other species with genetic sex determination.

Bioassay methods that include thyroid-related endpoints have been developed in a variety of species, including amphibians, whose metamorphic development is thyroid hormone (TH)-dependent. Inhibition of TH synthesis in these species leads to developmental delay, and assays designed to capture these effects take several weeks to complete. In an effort to develop a shorter term approach, the early responses of various endpoints were evaluated in Xenopus laevis throughout 8d of exposure to three TH synthesis inhibitors: methimazole (100mg/L), 6-propylthiouracil (6-PTU) (20mg/L), and perchlorate (4mg/L). Endpoints included thyroid gland histology and cell numbers, circulating TH concentrations, and thyroidal TH and associated iodo-compounds. Thyroidal 3,5-diodo-l-tyrosine (DIT) and thyroxine (T4) were significantly reduced from day 2 onward by all three chemicals, while 3-monoiodo-l-tyrosine (MIT) was significantly reduced by methimazole and perchlorate, but not by 6-PTU. These reductions were the earliest indicators of TH synthesis inhibition. Histological effects were apparent on day 4 and became more exaggerated through day 8. However, reductions in circulating T4 and increases in thyroid gland cell numbers were not apparent until day 6. Reductions of thyroidal MIT, DIT, and T4 and circulating T4 are indicative of inhibitory effects of the chemicals on TH synthesis. Changes in thyroid histology and cell number represent compensatory effects modulated by circulating TSH. These observations establish a basis for the development of short term amphibian-based methods to evaluate thyroid axis effects using a suite of diagnostic endpoints.

CMAQ representation of the regional nitrogen budget is limited by its treatment of ammonia (NH3) soil emission from, and deposition toaaunderlying surfaces as independent rather than tightly coupled processes, and by its reliance on soil emission estimates that do not respond to variable meteorology and ambient chemical conditions. The present study identifies an approach that addresses these limitations, lends itself to regional application, and will better position CMAQ to meet future assessment challenges. These goals were met through the integration of the resistance-based flux model of Nemitz et al. (2001) with elements of the United States Department of Agriculture EPIC (Environmental Policy Integrated Climate) model. Model integration centers on the estimation of ammonium and hydrogen ion concentrations in the soil required to estimate soil NH3 flux. The EPIC model was calibrated using data collected during an intensive 2007 field study in Lillington, North Carolina. A simplified process model based on the nitrification portion of EPIC was developed and evaluated. It was then combined with the Nemitz et al. (2001) model and measurements of near-surface NH3 concentrations to simulate soil NH3 flux at the field site. Finally, the integrated flux (emission) results were scaled upward and compared to recent national ammonia emission inventory estimates. The integrated model results are shown to be more temporally resolved (daily), while maintaining good agreement with established soil emission estimates at longer time-scales (monthly). Although results are presented for a single field study, the process-based nature of this approach and NEI comparison suggest that inclusion of this flux model in a regional application should produce useful assessment results if nationally consistent sources of driving soil and agricultural management information are identified.

Large pulses of contaminants such as this event may occur more often given evidence of increased variability of precipitation and hydrologic extremes occurring with climate change [Intergovernmental Panel on Climate Change (IPCC), 2007]. Conversion of land to human-dominated uses has increased contaminant loads in streams and rivers and further transformed hydrologic cycles [Vitousek et al., 1997]. Together, land use and climate change may interact in unexpected ways to alter the amplitude, frequency, and duration of contaminant pulses in streams and rivers (i.e., large contaminant loads that are transported over relatively short time scales).

The components of the EPA's safety analysis, which includes food and drinking water exposures, MRL establishment, as well as evaluations for worker exposure and risk, and ecological effects will be presented. EPA assessments relative to evaluating the safety of new drugs from the standpoint of resistant bacteria will be covered. In this regard, EPA is using an approach similar to that of FDA to characterize the safety of antimicrobial drugs, which will be described. Milestones around the public participation process EPA applies to first domestic food uses will be explained as well as plans for direct dialogue and coordination with partner agencies, such as FDA and CDC. Regulatory mechanisms that may be available through FIFRA labeling to enhance the safety and utility of antibiotics used in agriculture will be discussed. In addition, post registration considerations such as monitoring for the development of resistant bacteria will be summarized for discussion.

Information on tool use, development and research needs, was gathered from websites, documents, and CBCRA program participants and researchers, including 25 project officers who work directly with community groups. The tools were assessed on the basis of information provided by project officers, community members, CBCRA researchers, and by case study applications. Tables summarize key environmental issues and tool features: (1) a listing of CBCRA-related environmental issues of concern to communities; (2) web-based tools that map environmental information; (3) step-by-step guidance documents; (4) databases of environmental information; and (5) computer models that simulate human exposure to chemical stressors. All tools described here are publicly available, with the focus being on tools developed by the US Environmental Protection Agency. These tables provide sources of information to promote risk identification and prioritization beyond risk perception approaches, and could be used by CBCRA participants and researchers. The purpose of this overview is twofold: (1) To present a comprehensive, though not exhaustive, summary of numerous tools that could aid with performing CBCRAs; and (2) To use this toolset as a sample of the current state of CBCRA tools to critically examine their utility and guide research for the development of new and improved tools.

Additional challenges include determining what scientific tools are available and most relevant, and understanding how to use those tools; given these barriers, community groups tend to rely more on risk perception than science. The U.S. Environmental Protection Agency's Office of Research and Development, National Exposure Research Laboratory (NERL) and collaborators are developing and applying tools (models, data, methods) for enhancing cumulative risk assessments. The NERL's 'Cumulative Communities Research Program' focuses on key science questions: (1) How to systematically identify and prioritize key chemical stressors within a given community?; (2) How to develop estimates of exposure to multiple stressors for individuals in epidemiologic studies?; and (3) What tools can be used to assess community-level distributions of exposures for the development and evaluation of the effectiveness of risk reduction strategies? This paper provides community partners and scientific researchers with an understanding of the NERL research program and other efforts to address cumulative community risks; and key research needs and opportunities. Some initial findings include the following: (1) Many useful tools exist for components of risk assessment, but need to be developed collaboratively with end users and made more comprehensive and user-friendly for practical application; (2) Tools for quantifying cumulative risks and impact of community risk reduction activities are also needed; (3) More data are needed to assess community- and individual-level exposures, and to link exposure-related information with health effects; and (4) Additional research is needed to incorporate risk-modifying factors ('non-chemical stressors') into cumulative risk assessments. The products of this research program will advance the science for cumulative risk assessments and empower communities with information so that they can make informed, cost-effective decisions to improve public health.

Here, we examined how precipitation alters the ecological effects of ocean water intrusion to coastal dunes on two oceanic carbonate islands in the Bahamas. The approach was to compare sites that receive high and low annual rainfall and are also characterized by seasonal distribution (wet and dry season) of precipitation. The spatial and temporal variations in precipitation serve as a proxy for conditions of altered precipitation which may occur via climate change. We used the natural abundances of stable isotopes to identify water sources (e.g., precipitation, groundwater and ocean water) in the soil-plant continuum and modeled the depth of plant water uptake. Results indicated that decreased rainfall caused the shallow freshwater table on the dune ecosystem to sink and contract towards the inland, the lower freshwater head allowed ocean water to penetrate into the deeper soils, while shallow soils became exceedingly dry. Plants at the drier site that lived nearest to the ocean responded by taking up water from the deeper and consistently moist soil layers where ocean water intruded. Towards the inland, decreased rainfall caused the water table to sink to a depth that precluded both recharge to the upper soil layers and access by plants. Consequently, plants captured water in more shallow soils recharged by infrequent rainfall events. The results demonstrate dune ecosystems on oceanic islands are more susceptible to ocean water intrusion when annual precipitation decreases. Periods of diminished precipitation caused drought conditions, increased exposure to saline marine water and altered water-harvesting strategies. Quantifying species tolerances to ocean water intrusion and drought are necessary to determine a threshold of community sustainability.

In recent years, a transgenic corn expressing the Cry3Bb1 toxin has been successfully used for protection against corn rootworm larvae (genus Diabrotica). The biological action of the Bt toxin in corn rootworms has not yet been clearly defined. Because development of resistance to Bt by corn rootworms will have huge economic and ecological costs, insight into larval response to Bt toxin is highly desirable. We identified 19 unique transcripts that are differentially expressed in D. virgifera virgifera larvae reared on corn transgenic for Cry3Bb1. Putative identities of these genes were consistent with impacts on metabolism and development. Analysis of highly modulated transcripts resulted in the characterization of genes coding for a member of a cysteine-rich secretory protein family and a glutamine-rich membrane protein. A third gene that was isolated encodes a nondescript 132 amino acid protein while a fourth highly modulated transcript could not be further characterized. Expression patterns of these four genes were strikingly different between susceptible and resistant western corn rootworm populations. These genes may provide useful targets for monitoring of Bt exposure patterns and resistance development in pest and non-target insect populations.

However, the use of urban marine habitats may have consequences for bird populations, as birds can be subject to stress from increased levels of passive and active human disturbance. We examined the effects of human disturbance, available foraging habitat, and prey abundance on wading bird density and species richness at 17 urban coastal sites in Narragansett Bay, Rhode Island USA. The sites represented a gradient of immediately adjacent residential and commercial land use (e.g., 0.0-67.7% urban land use within a 30.5m buffer of the sites) within an urban matrix (i.e., all sites were located within a suburban center with a population of about 85,000 people). Wading bird density (0.62 plus or minus 0.12 birds ha super(-1)) and species richness (average 4.49 plus or minus 0.37 species across all sites) were not influenced by passive human disturbance as measured by the extent of urban land surrounding a site. However, wading bird density and species richness both decreased significantly as active disturbance (i.e., number of boats moored or docked upstream of the site) increased (r=-0.56, F=6.85, p=0.019 and r=-0.73, F=16.6, p=0.001, respectively). In addition, both density (r=0.72, F=16.2, p=0.001) and species richness (r=0.72, F=16.2, p=0.001) increased concomitantly with a prey index that combines the density of fish and invertebrates on which the birds feed with the amount of available shallow water foraging habitat at a site. Our results suggest that wading birds i) may not be negatively affected by urban land surrounding estuarine foraging areas in and of itself; and ii) may be utilizing urban areas in the absence of high levels of active disturbance to take advantage of potentially enhanced prey resources. In the case where the benefits of foraging at a site outweigh the costs related to human disturbance, urban marine habitats may need to be considered for restoration or protection from further increases in active human disturbance.

The main environmental limitations of much of the land used for olive orchards in the Mediterranean are the steep slopes and the shallow soil depth--and this was the case in the study area. Soil erosion and runoff over two hydrological years (2005-2006 and 2006-2007) were monitored in an olive orchard microcatchment of 6.1 ha under no-tillage with spontaneous grass in order to evaluate its hydrological and erosive behaviour. Moreover, soil parameters such as organic matter (%OM), bulk density (BD) and hydraulic saturated conductivity (Ks) were also examined in the microcatchment to describe management effects on hydrological balance and on erosive processes. In the study period, the results showed runoff coefficients of 6.0% in the first year and 0.9% in the second. The differences respond to the impact of two or three yearly maximum events which were decisive in the annual balances. On the event scale, although maximum rainfall intensity values had a big influence on peak flows and runoff, its importance on mean sediment concentrations and sediment discharges was difficult to interpret due to the likely control of grass cover on volume runoff and on soil protection. In the case of annual soil erosion, they were measured as 1.0 Mg ha (super -1) yr (super -1) and 0.3 Mg ha (super -1) yr (super -1) . Both are lower than the tolerance values evaluated in Andalusia (Spain). These results support the implementation of no-tillage with spontaneous grass cover for sloping land, although the reduced infiltration conditions determined by Ks in the first horizon suggest grass should be allowed to grow not only in spring but also in autumn. In addition, specific measurements to control gullies, which have formed in the terraced area in the catchment, should be included since it is expected that they could be the main sources of sediments.

AN - 733959563; 20188755 AB - Throughout development neurons undergo a number of morphological changes including neurite outgrowth from the cell body. Exposure to neurotoxic chemicals that interfere with this process may result in permanent deficits in nervous system function. Traditionally, rodent primary neural cultures and immortalized human and non-human clonal cell lines have been used to investigate the molecular mechanisms controlling neurite outgrowth and examine chemical effects on this process. The present study characterizes the molecular phenotype of hN2 human embryonic stem cell (hESC)-derived neural cells and uses automated high-content image analysis to measure neurite outgrowth in vitro. At 24h post-plating hN2 cells express a number of protein markers indicative of a neuronal phenotype, including: nestin, beta(III)-tubulin, microtubule-associated protein 2 (MAP2) and phosphorylated neurofilaments. Neurite outgrowth in hN2 cells proceeded rapidly, with a majority of cells extending one to three neurites by 48h in culture. In addition, concentration-dependent decreases in neurite outgrowth and ATP-content were observed following treatment of hN2 cells with either bisindolylmaleimide I, U0126, lithium chloride, sodium orthovanadate and brefeldin A, all of which have previously been shown to inhibit neurite outgrowth in primary rodent neural cultures. Overall, the molecular phenotype, rate of neurite outgrowth and sensitivity of hN2 cells to neurite outgrowth inhibitors were comparable to other in vitro models previously characterized in the literature. hN2 cells provide a model in which to investigate chemical effects on neurite outgrowth in a non-transformed human-derived cells and provide an alternative to the use of primary rodent neural cultures or immortalized clonal cell lines.

AN - 733547294; 19293846 AB - Community-based programs for assessing and mitigating environmental risks represent a challenge to participants because each brings a different level of understanding of the issues affecting the community. These programs often require the collaboration of several community sectors, such as community leaders, local governments and researchers. Once the primary concerns, community vulnerabilities and assets are identified, participants plan on how to address immediate actions, rank known risks, collect information to support decision making, set priorities and determine an evaluation process to assess the success of the actions taken. The evaluation process allows the community to develop new action plans based on the results obtained from earlier actions. Tracking the success of the community actions may be as simple as a visual/tangible result (e.g., cleaning a park) or as complex as the collection of specific measurements to track the reduction of toxic pollutants or to determine the presence of a specific contaminant. Recognizing that communities may need to perform measurements to meet their goals, this paper provides an overview of the available measurement methods for several chemicals and biologicals in relevant environmental samples to a community setting. The measurement methods are organized into several categories according to their level of complexity, estimated cost and sources. Community project technical advisors are encouraged to examine the objective(s) of the community to be addressed by a measurement collection effort and the level of confidence that needed for the data to make appropriate decisions. The tables provide a starting point for determining which measurement method may be appropriate for specific community needs.

AN - 733333911; 20544697 AB - Hemimelic extra toes (Hx) arose spontaneously as a dominant mutation in B10.D2/nSnJ mice in 1967. It specifically affects the appendicular skeleton, causing variable foreshortening of the tibia (radius) and preaxial polydactylism. Early anatomical studies revealed anterior overgrowth of the autopod, with decreased apoptosis and increased mitosis in the anterior apical ectodermal ridge and underlying mesenchyme; overextension of apoptosis in the central zeugopod accounted for hemimelia. The Hx mutant phenotype was coarsely mapped to mouse chromosome (Chr) 5 and closely linked to engrailed-2 (En2) and Sonic hedgehog (Shh). This region is syntenic to human Chr 7q36 that harbors several dominant mutations affecting the hand. High-resolution genome mapping identified the Hx mutation as a G --> A base pair transition within Intron 5 of the murine Lmbr1 locus. The critical effect is on a multifunctional conserved regulatory element that acts as a limb-specific, long-distance cis-acting enhancer of Shh expression. As such, the Hx mutant phenotype results from ectopic Shh signals at the anterior margin of the limb bud that directly or indirectly alter FGF4 signaling from the apical ectodermal ridge. Given significant advances in understanding of embryonic development in general and limb development in particular, this review article reveals how research that once attracted interest of teratologists has advanced across the decades to pinpoint a critical molecular lesion and reveal a potential mechanism of a specific malformation that is found commonly in experimental teratology.

This paper describes the implementation of a real-time Kalman Filter (KF) bias-adjustment technique to improve the accuracy of O3 and PM2.5 forecasts at discrete monitoring locations. The operational surface-level O3 and PM2.5 forecasts from the NAQFC system were post-processed by the KF bias-adjusted technique using near real-time hourly O3 and PM2.5 observations obtained from EPA's AIRNow measurement network. The KF bias-adjusted forecasts were created daily, providing 24-h hourly bias-adjusted forecasts for O3 and PM2.5 at all AIRNow monitoring sites within the CONUS domain. The bias-adjustment post-processing implemented in this study requires minimal computational cost; requiring less than 10aamin of CPU on a single processor Linux machine to generate 24-h hourly bias-adjusted forecasts over the entire CONUS domain. The results show that the real-time KF bias-adjusted forecasts for both O3 and PM2.5 have performed as well as or even better than the previous studies when the same technique was applied to the historical O3 and PM2.5 time series from archived AQF in earlier years. Compared to the raw forecasts, the KF forecasts displayed significant improvement in the daily maximum 8-h O3 and daily mean PM2.5 forecasts in terms of both discrete (i.e., reduced errors, increased correlation coefficients, and index of agreement) and categorical (increased hit rate and decreased false alarm ratio) evaluation metrics at almost all locations during the study period in 2008.

13199395 AB - Polybrominated diphenyl ethers (PBDEs) are used as additive flame retardants and have been detected in human blood, adipose tissue, and breast milk. Both in vitro and in vivo studies have shown that the effects of PBDEs are similar to the known human developmental neurotoxicants such as polychlorinated biphenyls (PCBs) on a molar basis. Previously, we reported that PBDE mixtures and congeners, perturbed calcium homeostasis which is critical for the development and function of the nervous system. In the present study, we tested whether environmentally relevant PBDE/PCB mixtures and congeners affected mitogen-activated protein kinase (MAPK) pathways, which are down-stream events of calcium signaling in cerebellar granule neuronal cultures. In this study, phosphorylated extracellular signal-regulated kinase (pERK)1/2, a widely studied MAPK cascade and known to be involved in learning and memory, levels were quantitated using western blot technique with phospho-specific antibodies. Glutamate (a positive control) increased pERK1/2 in a time- and concentration-dependent manner reaching maximum activation at 5-30 min of exposure and at doses greater than or equal to 10 mu M. Both Aroclor 1254 (a commercial penta PCB mixture) and DE-71 (a commercial penta PBDE mixture) elevated phospho-ERK1/2, producing maximum stimulation at 30min and at concentrations greater than or equal to 3 mu g/ml; Aroclor 1254 was more efficacious than DE-71. DE-79 (an octabrominated diphenyl ether mixture) also elevated phospho-ERK1/2, but to a lesser extent than that of DE-71. PBDE congeners 47, 77, 99, and 153 also increased phospo-ERK1/2 in a concentration-dependent manner. The data indicated that PBDE congeners are more potent than the commercial mixtures. PCB 47 also increased phospho-ERK1/2 like its structural analog PBDE 47, but to a lesser extent, suggesting that these chemicals affect similar pathways. Cytotoxicity, measured as %LDH release, data showed that higher concentrations (>30 mu M) and longer exposures (>30min) are required to see cell death. These results show that PBDE mixtures and congeners activate MAPK pathway at concentrations where no significant cytotoxicity was observed, suggesting that perturbed intracellular signaling including MAPK pathway might be involved in the initiation of adverse effects, including learning and memory, related to these persistent chemicals.

Evaluation of the TE-GC-GC-MS method shows high average relative accuracy ( greater than or equal to 90%), reproducibility ( less than or equal to 10% relative standard deviation), detection limits of less than 3 ng/ mu L, and negligible carryover for levoglucosan, mannosan, and galactosan markers. TE-GC-GC-MS- and solvent extraction (SE)-GC-MS-measured levoglucosan concentrations correlate across several diverse types of biomass burning aerosols. Because the SE-GC-MS measurements were taken 8 years prior to the TE-GC-GC-MS ones, the stability of levoglucosan is established for quartz filter-collected biomass burning aerosol samples stored at ultra-low temperature (− 50 degree C). Levoglucosan concentrations (w/w) in aerosols collected following atmospheric dilution near open fires of varying intensity are similar to those in biomass burning aerosols produced in a laboratory enclosure. An average levoglucosan-mannosan-galactosan ratio of 15:2:1 is observed for these two aerosol sets. TE-GC-GC-MS analysis of atmospheric aerosols from the US and Africa produced levoglucosan concentrations (0.01-1.6 mu g/m super(3)) well within those reported for aerosols collected globally and examined using different analytical techniques (0.004-7.6 mu g/m super(3)). Further comparisons among techniques suggest that fast TE-GC-GC-MS is among the most sensitive, accurate, and precise methods for compound-specific quantification of anhydro-sugars. In addition, an approximately twofold increase in anhydro-sugar determination may be realized when combining TE with fast chromatography.

We reviewed evidence on the impact of environmental chemicals on lung development and key signaling events in lung morphogenesis, and the relevance of potential outcomes to public health and regulatory science. We evaluated the peer-reviewed literature on developmental lung biology and toxicology, mechanistic studies, and supporting epidemiology. Lung function in infancy predicts pulmonary function throughout life. In utero and early postnatal exposures influence both childhood and adult lung structure and function and may predispose individuals to chronic obstructive lung disease and other disorders. The nutritional and endogenous chemical environment affects development of the lung and can result in altered function in the adult. Studies now suggest that similar adverse impacts may occur in animals and humans after exposure to environmentally relevant doses of certain xenobiotics during critical windows in early life. Potential mechanisms include interference with highly conserved factors in developmental processes such as gene regulation, molecular signaling, and growth factors involved in branching morphogenesis and alveolarization. Assessment of environmental chemical impacts on the lung requires studies that evaluate specific alterations in structure or function--end points not regularly assessed in standard toxicity tests. Identifying effects on important signaling events may inform protocols of developmental toxicology studies. Such knowledge may enable policies promoting true primary prevention of lung diseases. Evidence of relevant signaling disruption in the absence of adequate developmental toxicology data should influence the size of the uncertainty factors used in risk assessments.

In recent years, photosynthetic bacteria along with their wide adaptability are commonly used in sewage treatment. The photosynthetic bacteria which are isolated from the sea have a high salt tolerance. A feasibility study of the photosynthetic bacteria with UASB Process treatment of high-salinity organic wastewater is presented in this paper. With the concentration of seawater proportion gradually (12%, 24%, 36%) increasing, the gradient acclimatization is tested to explore the effect of salinity on the degradation of organic matter and to determine the biological contact oxidation system operating parameters.

The hypothesis that contaminant concentrations in a high-elevation portion of the Sierra Nevada decrease with distance from the adjacent San Joaquin Valley was tested. Air, sediment, and tadpoles were sampled twice at 28 water bodies in 14 dispersed areas in Sequoia and Kings Canyon National Parks (2,785-3,375 m elevation; 43-82 km from Valley edge). Up to 15 chemicals were detected frequently in sediment and tadpoles, including current- and historic-use pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons. Only beta -endosulfan was found frequently in air. Concentrations of all chemicals detected were very low, averaging in the parts-per-billion range or less in sediment and tadpoles, and on the order of 10 pg/m (super 3) for beta -endosulfan in air. Principal components analysis indicated that chemical compositions were generally similar among sites, suggesting that chemical transport patterns were likewise similar among sites. In contrast, transport processes did not appear to strongly influence concentration differences among sites, because variation in concentrations among nearby sites was high relative to sites far from each other. Moreover, a general relationship for concentrations as a function of distance from the valley was not evident across chemical, medium, and time. Nevertheless, concentrations for some chemical/medium/time combinations showed significant negative relationships with metrics for distance from the Valley. However, the magnitude of these distance effects among high-elevation sites was small relative to differences found in other studies between the valley edge and the nearest high-elevation sites.

After a steady state distribution was achieved with a seaward hydraulic gradient, freshwater was introduced while keeping the total head constant at each boundary. This caused the propagation of freshwater seaward. Two initial uniform concentrations were used: Case 1: 2.0 g/L (low salinity case) and Case 2: 34.0 g/L (high salinity case). The observed salinity and pressure data were closely reproduced using the MARUN (Boufadel et al. 1999a) numerical code. The results indicated that buoyancy plays an important role for Case 2 but is negligible for Case 1. The results also indicated that the flow in the offshore beach aquifer (submerged portion of beach) was negligible especially for Case 2. For this case, the pressure increased with time until reaching a peak and then decreased (i.e., humps were formed). This was not observed in the low salinity case. Investigations revealed that the increase in pressure is due to a combination of remnant high salinity and a rise in the water table at that location. Numerical investigations revealed that for the same difference in total head, the seaward flow of freshwater increases with a decrease in the seawater salinity. The increase, however, was nonlinear as a function of seawater density. For example, the discharge in the high salinity case was 20% lower than that in the low salinity case.

We measured NH4+ and PO4-3 uptake length (Sw), uptake velocity (Vf), uptake rate (U), biofilm respiration and enzyme activity and channel geomorphology in streams draining forested catchments in the northwestern (Northern California Coast Range and Cascade Mountains) and southeastern (Appalachian and Ouachita mountains) regions of the United States. Our goal was to use measures of biofilm enzyme activity and nutrient uptake to assess nutrient limitation in forested streams across broad regional scales.2. Geomorphological attributes, biofilm enzyme activity and NH4+ uptake were significantly different among streams in the four study units. There was no study unit effect on PO4-3 uptake. The proportion of the stream channel in pools, % woody debris, % canopy closure, median substrate size (d50), stream width (w), stream velocity (v), discharge (Q), dispersion coefficient (D) and transient storage (As-A) were correlated with biofilm enzyme activity and nutrient uptake in some study units.3. Canonical correlation analyses across study units revealed significant correlations of NH4-Vf and PO4-Vf with geomorphological attributes (w, d50, D, % woody debris, channel slope and % pools) and biofilm phosphatase activity.4. The results did not support our expectation that carbon processing rates by biofilm microbial assemblages would be governed by stream nutrient availability or that resulting biofilm enzyme activity would be an indicator of nutrient uptake. However, the relative abundances of peptidases, phosphatase and glycosidases did yield insight into potential N-, P- and C-limitation of stream biofilm assemblages, and our use of biofilm enzyme activity represents a novel application for understanding nutrient limitations in forested streams.5. Regressions of Vf and U against ambient NH4+ and PO4-3 indicated that none of our study streams was either NH4+ or PO4-3 saturated. The Appalachian, Ouachita and Coastal streams showed evidence of NH4+ limitation; the Ouachita and Coastal streams were PO4-3 limited. As a correlate of nutrient limitation and saturation in streams, ratios of total aminopeptidase and phosphatase activities and the ratio of NH4-U to PO4-U indicate these forested streams are predominantly N-limited, with only the streams draining Ouachita and Coastal catchments demonstrating appreciable levels of P-limitation.6. Our results comparing the stoichiometry of microbial enzyme activity with nutrient uptake ratios and with the molar ratios N and P in stream waters suggest that biological limitations are not strictly the result of stream chemistry and that the assessments of nutrient limitations in stream ecosystems should not be based on chemistry alone.7. Our present study, along with previous work in streams, rivers and wetlands, suggests that microbial enzyme activities, especially the ratios of total peptidases to phosphatase, are useful indicators of nutrient limitations in aquatic ecosystems.

Effects of a dopamine receptor antagonist on fathead minnow, Pimephales promelas, reproduction AN - 746079371; 13030132 AB - Neurotransmitters such as dopamine play an important role in regulating fish reproduction. However, the potential for neuroendocrine active chemicals to disrupt fish reproduction has not been well studied, despite emerging evidence of their discharge into aquatic environments. This study is the first to apply the fathead minnow 21d reproduction assay developed for the US Endocrine Disruptor Screening Program to evaluate the reproductive toxicity of a model neuroendocrine active chemical, the dopamine 2 receptor antagonist, haloperidol. Continuous exposure to up to 20 mu ghaloperidol/L had no significant effects on fathead minnow fecundity, secondary sex characteristics, gonad histology, or plasma steroid and vitellogenin concentrations. The only significant effect observed was an increase in gonadotropin-releasing hormone (cGnRH) transcripts in the male brain. Results suggest that non-lethal concentrations of haloperidol do not directly impair fish reproduction. Potential effects of haloperidol on reproductive behaviors and gene expression were examined in a companion study.

Traditionally, the assessment of gonad phenotype is done via histology, which involves specialized and time-consuming techniques. The method detailed here increases the efficiency of the analysis by first determining the relative expression of four genes involved in gonad development/maintenance in Japanese medaka (Oryzias latipes), and then by using principal component analysis, assigning a phenotype to each gonad based upon the gene expression data. The gonad phenotype and the sexual genotype, which can be determined in medaka, can then be compared to assess potential adverse effects of exposure to endocrine disrupting chemicals.

The integration of modern computing with molecular biology and chemistry will allow scientists to better prioritize data, inform decision makers on chemical risk assessments and understand a chemical's progression from the environment to the target tissue within an organism and ultimately to the key steps that trigger an adverse health effect. In this paper, several of the major research activities being sponsored by Environmental Protection Agency's National Center for Computational Toxicology are highlighted. Potential links between research in computational toxicology and human exposure science are identified. As with the traditional approaches for toxicity testing and hazard assessment, exposure science is required to inform design and interpretation of high-throughput assays. In addition, common themes inherent throughout National Center for Computational Toxicology research activities are highlighted for emphasis as exposure science advances into the 21st century.

In order to address this, the bacterial diversity of membrane biofilm reactors (MBfR) set up under autotrophic denitrifying and perchlorate-reducing conditions were examined by analyses of the 16S rRNA gene sequences of clone libraries. Inocula from diverse locations were tested for their ability to reduce nitrate and perchlorate in synthetic ion exchange spent brine (45 g/l NaCl) using H sub(2)-based MBfRs. Phylogenetic analysis of 16S rRNA gene sequences showed that proteobacterial species dominated the biofilm communities, particularly nitrate-reducing g-proteobacteria. Even though the inocula to the MBfRs came from different sources, clones closely related to Marinobacter hydrocarbonoclasticus represented 53% of all clones in the MBfR biofilms. The clone libraries contained no known perchlorate-reducing bacteria, which suggest that denitrifiers carried out perchlorate reduction, probably by secondary-utilization.

Establishing the extent of these biological responses as the system approaches a new equilibrium allows us more reliably to emulate comparable native systems. That is, the sensitivity of analyzing ecosystem processes in a reconstructed system is improved by excluding the period when observed phenomena are primarily responses caused by establishing the experiment rather than effects of imposed treatments; achieved by determining the extent of any pulse of activity caused by preparatory procedures. A native forest soil was physically disrupted when it was collected, sieved, and then rebuilt in lysimeters in a controlled-environment study evaluating the influence of elevated atmospheric CO sub(2) concentration and elevated atmospheric temperature on the reconstructed soil that was planted with Douglas-fir (Pseudotsuga menziesii Mirb. Franco) seedlings. Generally, soil food web populations responded in two phases during the exposure as indicated by preliminary evaluation of the 4.5-year dataset. Also, previous work indicated that relatively elevated soil CO sub(2) effluxes occurred during the first phase, suggesting that food web populations may have responded to carbon sources made available when the soil was harvested and its profile reconstructed in the lysimeters. Results are presented for bacterial and fungal biomass, numbers of protozoa and nematodes to gain insight on whether the first phase responses are attributable to the acute stress of physically disrupting the soil. We found clear relationships between changes in predator and prey populations. A prominent spike for many of the food web populations occurred the year after the climate exposures began. Except for total bacterial biomass and total fungal-hyphae biomass, overall food web responses generally were unrelated to treatments. It appears that initial food web population responses were related to increased availability of soil carbon caused by establishing the experiment. Our results provide insights into determining the length of time to maintain reconstructed forest ecosystems before responses are observed related to experimental treatments. It appears that as long as 3 years elapsed before the soil food web appeared to recover from the acute physical disturbance; 1 year of recovery prior to commencing the climate exposures to allow the soil to rest after it was reconstructed, plus approximately the first 2 years of maintaining the climate treatments. Accounting for consequences of such periods of adjustment is critical for forecasting whether comparable natural ecosystems will be net sources or sinks of elevated concentrations of atmospheric CO sub(2).

AN - 733899008; 20235799 AB - A report by the Institute of Medicine suggested that more research is needed to better understand mold effects on allergic disease, particularly asthma development. The authors compared the ability of the fungus Stachybotrys chartarum (SCE) and house dust mite (HDM) extracts to induce allergic responses in BALB/c mice. The extracts were administered by intratracheal aspiration (IA) at several doses (0, 2.5, 5, 10, 20, 40, and 80 microg) 4 times over a 4-week period. Three days after the last IA exposure, serum and bronchoalveolar lavage fluid (BALF) were collected. The relative allergenicity of the extracts was evaluated based on the lowest dose that induced a significant response compared to control (0 microg) and the linear regression slope analysis across the dose range. SCE induced a more robust response than HDM for BALF some inflammatory cells (macrophage and neutrophils), whereas HDM induced more robust BALF lymphocyte and eosinophil responses. Although SCE induced a more robust serum total immunoglobulin E (IgE) response than did HDM, the induction of a similar response in a functional, antigen-specific IgE assay required approximately twice as much SCE as HDM. Even though SCE demonstrates the ability to induce allergic responses in the mouse model, considering the importance and relevance of eosinophil, lymphocyte, and antigen-specific IgE in allergic airway disease, it is concluded that HDM is more potent than SCE in the induction of allergic responses. These data suggest a threshold dose for SCE allergy induction. Furthermore, in damp water-damaged environments, exposure to S. chartarum might easily exceed the sensitization threshold for a susceptible population.

AN - 733895144; 20064898 AB - The mouse liver tumorigenic conazole fungicides triadimefon and propiconazole have previously been shown to be in vivo mouse liver mutagens in the Big Blue transgenic mutation assay when administered in feed at tumorigenic doses, whereas the non-tumorigenic conazole myclobutanil was not mutagenic. DNA sequencing of the mutants recovered from each treatment group as well as from animals receiving control diet was conducted to gain additional insight into the mode of action by which tumorigenic conazoles induce mutations. Relative dinucleotide mutabilities (RDMs) were calculated for each possible dinucleotide in each treatment group and then examined by multivariate statistical analysis techniques. Unsupervised hierarchical clustering analysis of RDM values segregated two independent control groups together, along with the non-tumorigen myclobutanil. The two tumorigenic conazoles clustered together in a distinct grouping. Partitioning around mediods of RDM values into two clusters also groups the triadimefon and propiconazole together in one cluster and the two control groups and myclobutanil together in a second cluster. Principal component analysis of these results identifies two components that account for 88.3% of the variability in the points. Taken together, these results are consistent with the hypothesis that propiconazole- and triadimefon-induced mutations do not represent clonal expansion of background mutations and support the hypothesis that they arise from the accumulation of reactive electrophilic metabolic intermediates within the liver in vivo.

AN - 733853627; 20153349 AB - Dichloromethane (DCM, methylene chloride) is a lipophilic volatile compound readily absorbed and then metabolized to several metabolites that may lead to chronic toxicity in different target organs. Physiologically based pharmacokinetic (PBPK) models are useful tools for calculation of internal and target organ doses of parent compound and metabolites. PBPK models, coupled with in vivo inhalation gas-uptake data, can be useful to estimate total metabolism. Previously, such an approach was used to make predictions regarding the metabolism and to make subsequent inferences of DCM's mode of action for toxicity. However, current evidence warrants re-examination of this approach. The goal of this work was to examine two different hypotheses for DCM metabolism in mice. One hypothesis describes two metabolic pathways: one involving cytochrome P450 2E1 (CYP2E1) and a second glutathione (GSH). The second metabolic hypothesis describes only one pathway mediated by CYP2E1 that includes multiple binding sites. The results of our analysis show that the in vivo gas-uptake data fit both hypotheses well and the traditional analysis of the chamber concentration data is not sufficient to distinguish between them. Gas-uptake data were re-analyzed by construction of a velocity plot as a function of increasing DCM initial concentration. The velocity (slope) analysis revealed that there are two substantially different phases in velocity, one rate for lower exposures and a different rate for higher exposures. The concept of a "metabolic switch," namely that due to conformational changes in the enzyme after one site is occupied - a different metabolic rate is seen - is also consistent with the experimental data. Our analyses raise questions concerning the importance of GSH metabolism for DCM. Recent research results also question the importance of this pathway in the toxicity of DCM. GSH-related DNA adducts were not formed after in vivo DCM exposure in mice and DCM-induced DNA damage has been detected in human lung cultures without GSH metabolism. In summary, a revised/updated metabolic hypothesis for DCM has been examined using in vivo inhalation data in mice combined with PBPK modeling that is consistent with up-to-date models of the active site for CYP2E1 and suggests that this pathway is the major metabolizing pathway for DCM metabolism.

AN - 733578179; 20045049 AB - Low weight at birth is a common adverse developmental effect reported in human populations and animal toxicity studies. Epidemiological evidence links low birth weight to a syndrome of metabolic changes that increase later risk for obesity, type 2 diabetes, hypertension, and cardiovascular disease. The present study used a four-treatment cross-over experimental design to evaluate the selective impact of early nutritional deficiency on metabolism and brain function across the lifespan of male Sprague Dawley rats. Undernutrition was induced prenatally by restricting maternal food intake to 50% of ad lib from GD3 to birth. Postnatal undernutrition was induced by fostering pups at birth to naïve dams in large (n=16) litters as opposed to small (n=8) control litters. Body weights were monitored in the early neonatal period, in early adulthood beginning at 5months and through to senescence at 21months of age. In contrast to recent reports, no increase in the prevalence of obesity was seen in animals born to food restricted dams and reared under ad lib feeding conditions. Behavioral tests of locomotion, learning and memory were performed in young, middle-aged, and aged animals. No effects of pre or postnatal nutritional history were detected. Age-dependent reductions in locomotor activity were detected, as well as deficits in spatial learning as measured in the Morris water maze and in context fear conditioning. These findings indicate that moderate fetal undernutrition followed by neonatal adequate nutrition does not appear to lead to obesity or neurological dysfunction in young adulthood or old age.

Summary of a symposium presented at the annual meeting of the neurobehavioral teratology society, June, 2009. AN - 733577897; 20171276 AB - The National Research Council (NRC) of the National Academies of Science recently published a report of its vision of toxicity testing in the 21st century. The report proposes that the current toxicity testing paradigm that depends upon whole-animal tests be replaced with a strategy based upon in vitro tests, in silico models and evaluations of toxicity at the human population level. These goals are intended to set in motion changes that will transform risk assessment into a process in which adverse effects on public health are predicted by quantitative structure-activity relationship (QSAR) models and data from suites of high-throughput in vitro tests. The potential roles for whole-animal testing in this futuristic vision are both various and undefined. A symposium was convened at the annual meeting of the Neurobehavioral Teratology Society in Rio Grande, Puerto Rico in June, 2009 to discuss the potential challenges and opportunities for behavioral scientists in developing and/or altering this strategy toward the ultimate goal of protecting public health from hazardous chemicals. R. Kavlock described the NRC vision, introduced the concept of the 'toxicity pathway' (a central guiding principle of the NRC vision), and described the current status of an initial implementation this approach with the EPA's ToxCast(R) program. K. Crofton described a pathway based upon disruption of thyroid hormone metabolism during development, including agents, targets, and outcomes linked by this mode of action. P. Bushnell proposed a pathway linking the neural targets and cellular to behavioral effects of acute exposure to organic solvents, whose predictive power is limited by our incomplete understanding of the complex CNS circuitry that mediates the behavioral responses to solvents. B. Weiss cautioned the audience regarding a pathway approach to toxicity testing, using the example of the developmental toxicity of phthalates, whose effects on mammalian sexual differentiation would be difficult to identify based on screening tests in vitro. Finally, D. Rice raised concerns regarding the use of data derived from toxicity screening tests to human health risk assessments. Discussion centered around opportunities and challenges for behavioral toxicologists regarding this impending paradigm shift. Opportunities include: identifying and characterizing toxicity pathways; informing the conditions and limits of extrapolation; addressing issues of susceptibility and variability; providing reality-checks on selected positives and negatives from screens; and performing targeted testing and dose-response assessments of chemicals flagged during screening. Challenges include: predicting behavior using models of complex neurobiological pathways; standardizing study designs and dependent variables to facilitate creation of databases; and managing the cost and efficiency of behavioral assessments. Thus, while progress is being made in approaching the vision of 21st century toxicology, we remain a long way from replacing whole-animal tests; indeed, some animal testing will be essential for the foreseeable future at least. Initial advances will likely provide better prioritization tools so that animal resources are used more efficiently and effectively.

Obstacles to change are formidable. Educators debate their purpose - provide knowledge or achieve environmental goals - and we have limited evidence of the effectiveness of environmental programs and policies. Change requires collaboration across organizations and disciplines, targeted capacity building, and building systems of assessment into programs that enable more sophisticated evaluations. As in other fields, an evidence-based movement will increase the credibility and effectiveness of environmental education. A culture of evaluation offers educators a solid platform to collaboratively and efficiently achieve society's environmental goals.

Neuroendocrine-active chemicals in the environment have potential to interfere with and/or alter these processes. A companion study with the dopamine 2 receptor antagonist, haloperidol, found no evidence of a direct effect of the chemical on fish reproduction. This study considered haloperidol's potential effects on behavior and ovarian gene expression. Male fathead minnows exposed to 50 mu g haloperidol/L for 96h were found to be significantly more dominant than control males. In terms of molecular signaling, investigated using oligonucleotide microarrays, there was little similarity in the identity and functions of genes differentially expressed in the ovaries of fathead minnows (Pimephales promelas) versus zebrafish (Danio rerio) exposed under the same conditions. Results suggest that non-lethal concentrations of haloperidol do not induce ovarian molecular responses that could serve as biomarkers of exposure to D2R antagonists, but may impact behavior.

The spatial and temporal characteristics of these surfaces may reveal new information about the associations between emissions, pollution levels, and human exposure and health outcomes that may not have been discernable before. This paper presents four techniques, ranging from simple to complex, to statistically combine observed and modeled daily maximum 8-hr ozone concentrations for a domain covering the greater New York State area for the summer of 2001. Cross-validation results indicate that, for the domain and time period studied, the simpler techniques (additive and multiplicative bias adjustment) perform as well as or better than the more complex techniques. However, the spatial analyses of the resulting ozone concentration surfaces revealed some problems with these simpler techniques in limited areas where the model exhibits difficulty in simulating the complex features such as those observed in the New York City area.

Drinking water systems that employ riverbank filtration may receive additional treatment credits beyond that which they can obtain using traditional engineering approaches. In order to develop guidance for removal effectiveness, screening level predictive modeling by colloid filtration theory combined with advection and dispersion modeling is potentially useful. Currently, only few studies have measured basic effective colloid filtration parameters for Cryptosporidium oocysts with naturally occurring riverbank sediments. In the focus of this study we conducted flow column experiments in triplicate and measured effective attachment rate coefficients for sandy river sediments of the Southern Great Plains which are low in organic matter. We found that for sediment sampled from these high-energy rivers there was no apparent dependency of C. parvum removal with carbon content, bacterial colony forming units, or with gross texture properties of the sands. The differences in particle size distribution for the sediments suggested that straining did not play a role in removal efficiency. First-order colloid attachment rate coefficients followed lognormal distribution functions. The coefficients also appeared to be unrelated to the differences in particle size distributions of the sediments, bacterial counts, or levels of total carbon or total organic carbon. Using Monte Carlo analyses, the lowest observed 5th percentile was 8.0x10 super(-6) and the highest observed 95th percentile was 1.6x10 super(-3). Total log10 removals ranged from 23 to 200m super(-1). These results have application for screening level colloid filtration modeling of riverbank filtration in these systems.

However, present research on these fractures is mostly confined to qualitative descriptions. An accurate calculation of certain fracture parameters, such as openness, density, porosity and permeability, is of great importance to fracture quantitative descriptions and are also a fundamental factor in the development of oil and gas fields. This paper documents a study that constructs a relationship between ancient earth stress during the fracture-forming period and fracture parameters, and that between present earth stress and parameters; in this comparison, the study determines the characteristics and directions of ancient earth stress through a structural analysis and calculates the direction and strength of the present earth stress by using such means as sonic velocity, hydrofracturing, and sound emission. The results are introduced into the fracture parameter calculation model to simulate and calculate the openness, density, porosity and permeability of fractures in the 3rd sand set of the Paleogene Fu-2 member in the Qiaohekou Oilfield. It is concluded that fractures are highly developed in the structural high near the main fault and the differences in fracture permeability reflect the differences of their directions. Core statistics and log interpretation verify the correctness of the simulation results of the model.

13023706 AB - Immature rats are more susceptible than adults to the acute neurotoxicity of pyrethroid insecticides like deltamethrin (DLM). A companion kinetics study (Kim et al., in press) revealed that blood and brain levels of the neuroactive parent compound were inversely related to age in rats 10, 21, 40 and 90 days old. The objective of the current study was to modify a physiologically based pharmacokinetic (PBPK) model of DLM disposition in the adult male Sprague-Dawley rat (Mirfazaelian et al., 2006), so blood and target organ dosimetry could be accurately predicted during maturation. Age-specific organ weights and age-dependent changes in the oxidative and hydrolytic clearance of DLM were modeled with a generalized Michaelis-Menten model for growth and the summary equations incorporated into the PBPK model. The model's simulations compared favorably with empirical DLM time-courses in plasma, blood, brain and fat for the four age-groups evaluated (10, 21, 40 and 90 days old). PND 10 pups' area under the 24-h brain concentration time curve (AUC0-24h) was 3.8-fold higher than that of the PND 90 adults. Our maturing rat PBPK model allows for updating with age- and chemical-dependent parameters, so pyrethroid dosimetry can be forecast in young and aged individuals. Hence, this model provides a methodology for risk assessors to consider age-specific adjustments to oral Reference Doses on the basis of PK differences.

The possibilities of decreased precipitation and increased competition for water resources will be especially important for farmers who depend on rainfed agriculture. A study of coffee agroforestry systems in Southern Mexico (Chiapas, Mexico) was conducted to examine the ability of shade trees to maintain water availability for the coffee crop in a shade agroecosystem. Soil moisture, soil evaporation rates, and the evaporative transpiration potential of coffee plants were measured to examine the amount of water available to coffee plants and potential amount of water lost by the soil and coffee plants in systems under varying levels of shade cover. Soil evaporation and evaporative demand for crop transpiration were compared in coffee systems under different levels of shade canopy during both the wet season and dry season between July 2004 and June 2005. With 60-80% shade cover, daily soil evaporation rates significantly decreased by 41% compared to the low shade site (10-30% shade), although high levels of soil moisture were maintained in the dry season with only 30-65% shade cover. Coffee transpiration demand was strongly affected by shade cover as shade cover affects microclimate and the radiant energy within the system. Microclimate factors (light, temperature, and air saturation vapor pressure deficit) showed strong correlations to evaporative demand as a result. Shade cover a[control][yen30% showed significant reductions of 32% in evaporative transpiration demand when compared to the low shade site. The presence of shade cover in agroforestry systems is capable of reducing overall evaporative demand from soil evaporation and coffee transpiration, therefore offering a higher level of crop protection for farmers with agricultural vulnerability to reduced water resources.

The physical and chemical properties of the resulting particles were characterized. Two RDD simulation tests were conducted at Lawrence Livermore National Laboratory: one of the simulated RDDs was positioned 1m above a steel plate and the other was partially buried in soil. Particles were collected with filters at a distance of 150m from the origin of the RDD device, and particle mass concentrations were monitored to identify the particle plume intensity using real time particle samplers. Particles collected on filters were analyzed via computer-controlled scanning electron microscopy coupled with energy dispersive X-ray spectrometry (CCSEM/EDX) to determine their size distribution, morphology, and chemical constituents. This analysis showed that particles generated by the detonation of explosives can be associated with other materials (e.g., soil) that are in close proximity to the RDD device and that the morphology and chemical makeup of the particles change depending on the interactions of the RDD device with the surrounding materials.

AN - 733839620; 20045013 AB - Effective hazard screening will require the development of high-throughput or in vitro assays for the identification of potential sensitizers. The goal of this preliminary study was to identify potential biomarkers that differentiate the response to allergens vs non-allergens following an acute exposure in naïve individuals. Female BALB/c mice received a single intratracheal aspiration exposure to Metarhizium anisopliae crude antigen (MACA) or bovine serum albumin (BSA) in Hank's Balanced Salt Solution (HBSS) or HBSS alone. Mice were terminated after 1, 3, 6, 12, 18 and 24 h. Bronchoalveolar lavage fluid (BALF) was evaluated to determine total and differential cellularity, total protein concentration and LDH activity. RNA was isolated from lung tissue for microarray analysis and qRT-PCR. MACA administration induced a rapid increase in BALF neutrophils, lymphocytes, eosinophils and total protein compared to BSA or HBSS. Microarray analysis demonstrated differential expression of genes involved in cytokine production, signaling, inflammatory cell recruitment, adhesion and activation in 3 and 12 h MACA-treated samples compared to BSA or HBSS. Further analyses allowed identification of approximately 100 candidate biomarker genes. Eleven genes were selected for further assessment by qRT-PCR. Of these, 6 demonstrated persistently increased expression (Ccl17, Ccl22, Ccl7, Cxcl10, Cxcl2, Saa1), while C3ar1 increased from 6-24 h. In conclusion, a single respiratory exposure of mice to an allergenic mold extract induces an inflammatory response which is distinct in phenotype and gene transcription from the response to a control protein. Further validation of these biomarkers with additional allergens and irritants is needed. These biomarkers may facilitate improvements in screening methods. Copyright 2009 Elsevier Inc.

The meltwater flow from a continuous ice core melting system was split into two aliquots, with one aliquot directed to an inductively coupled plasma quadrupole mass spectrometer for continuous trace elements determinations and the second introduced into a solid phase C18 (SPE) cartridge for semicontinuous PAH extraction. The depth resolution for PAH extractions ranged from 40 to 70 cm, and corresponds to 0.7-5 years per sample. The concentrations of 11 PAH were determined in dated snow/ice samples to reconstruct the atmospheric concentration of these compounds in Europe for the last 300 years. The PAH pattern is dominated by phenanthrene (Phe), fluoranthene (Fla), and pyrene (Pyr), which represent 60-80% of the total PAH mass. Before 1875 the sum of PAH concentration (*SPAH) was very low with total mean concentrations less than 2 ng/kg and 0.08 ng/kg for the heavier compounds (*SPAH*, more than four aromatic rings). During the first phase of the industrial revolution (1770-1830) the PAH deposition showed a weak increase which became much greater from the start of the second phase of the industrial revolution at the end of 19th Century. In the 1920s, economic recession in Europe decreased PAH emissions until the 1930s when they increased again and reached a maximum concentration of 32 ng/kg from 1945 to 1955. From 1955 to 1975 the PAH concentrations decreased significantly, reflecting improvements in emission controls especially from major point sources, while from 1975 to 2003 they rose to levels equivalent to those in 1910. The Fla/(Fla+Pyr) ratio is often used for source assignment and here indicates an increase in the relative contribution of gasoline and diesel combustion with respect to coal and wood burning from 1860 to the 1980s. This trend was reversed during the last two decades.

AN - 754545351; 13269063 AB - The implicit assumption that biogenic secondary organic aerosol (SOA) is natural and can not be controlled hinders effective air quality management. Anthropogenic pollution facilitates transformation of naturally emitted volatile organic compounds (VOCs) to the particle phase, enhancing the ambient concentrations of biogenic secondary organic aerosol (SOA). It is therefore conceivable that some portion of ambient biogenic SOA can be removed by controlling emissions of anthropogenic pollutants. Direct measurement of the controllable fraction of biogenic SOA is not possible, but can be estimated through 3-dimensional photochemical air quality modeling. To examine this in detail, 22 CMAQ model simulations were conducted over the continental U.S. (August 15 to September 4, 2003). The relative contributions of five emitted pollution classes (i.e., NOx, NH3, SOx, reactive non methane carbon (RNMC) and primary carbonaceous particulate matter (PCM)) on biogenic SOA were estimated by removing anthropogenic emissions of these pollutants, one at a time and all together. Model results demonstrate a strong influence of anthropogenic emissions on predicted biogenic SOA concentrations, suggesting more than 50% of biogenic SOA in the eastern U.S. can be controlled. Because biogenic SOA is substantially enhanced by controllable emissions, classification of SOA as biogenic or anthropogenic based solely on VOC origin is not sufficient to describe the controllable fraction.

AN - 733814181; 20149836 AB - In vitro test methods can provide a rapid approach for the screening of large numbers of chemicals for their potential to produce toxicity (hazard identification). In order to identify potential developmental neurotoxicants, a battery of in vitro tests for neurodevelopmental processes such as cell proliferation, differentiation, growth, and synaptogenesis has been proposed. The development of in vitro approaches for toxicity testing will require choosing a model system that is appropriate to the endpoint of concern. This study compared several cell lines as models for neuronal proliferation. The sensitivities of neuronal cell lines derived from three species (PC12, rat; N1E-115, mouse; SH-SY5Y, human) to chemicals known to affect cell proliferation were assessed using a high content screening system. After optimizing conditions for cell growth in 96-well plates, proliferation was measured as the incorporation of 5-bromo-2'-deoxyuridine (BrdU) into replicating DNA during S phase. BrdU-labeled cells were detected by immunocytochemistry and cell counts were obtained using automated image acquisition and analysis. The three cell lines showed approximately 30-40% of the population in S phase after a 4h pulse of BrdU. Exposure to the DNA polymerase inhibitor aphidicolin for 20 h prior to the 4h pulse of BrdU significantly decreased proliferation in all three cell lines. The sensitivities of the cell lines were compared by exposure to eight chemicals known to affect proliferation (positive controls) and determination of the concentration inhibiting proliferation by 50% of control (I(50)). PC12 cells were the most sensitive to chemicals; 6 out of 8 chemicals (aphidicolin, cadmium, cytosine arabinoside, dexamethasone, 5-fluorouracil, and methylmercury) inhibited proliferation at the concentrations tested. SH-SY5Y cells were somewhat less sensitive to chemical effects, with five out of eight chemicals inhibiting proliferation; dexamethasone had no effect, and cadmium inhibited proliferation only at concentrations that decreased cell viability. Data from the N1E-115 cell line was extremely variable between experiments, and only 4 out of 8 chemicals resulted in inhibition of proliferation. Chemicals that had not been previously shown to alter proliferation (negative controls) did not affect proliferation or cell viability in any cell line. The results show that high content screening can be used to rapidly assess chemical effects on proliferation. Three neuronal cell lines exhibited differential sensitivity to the effect of chemicals on this endpoint, with PC12 cells being the most sensitive to inhibition of proliferation.

Thus there are possibilities of both increasing and decreasing river nutrients depending on national priorities. River flow rates which also influence the extent of hypoxia on the shelf may be altered by global climate change. We have therefore developed a series of simulations to forecast ecosystem response to alterations in nutrient loading and river flow. We simulate ecosystem response and hypoxia events using a linked model consisting of multiple phytoplankton groups competing for nitrogen, phosphorus and light, zooplankton grazing that is influenced by prey edibility and stoichiometry, sub-pycnocline water-column metabolism that is influenced by sinking fecal pellets and algal cells, and multi-element sediment diagenesis. This model formulation depicts four areas of increasing salinity moving westward away from the Mississippi River point of discharge, where the surface mixed layer, four bottom layers and underlying sediments are represented in each area. The model supports the contention that a 40% decrease in river nutrient will substantially reduce the duration and areal extent of hypoxia on the shelf. But it also suggests that in low and middle salinity areas the hypoxia response is saturated with respect to nutrients, and that in high salinity regions small increases in nutrient and river flow will have disproportionally large effects on GOM hypoxia. The model simulations also suggest that river discharge is a stronger factor influencing hypoxia than river nutrients in the Mississippi River plume. Finally, the model simulations suggest that primary production in the low salinity regions is light limited while primary production in the higher salinity zones is phosphate limited during the May to October period when hypoxia is prevalent in the Mississippi River plume.

Under pH and ionic conditions similar to natural water bodies, Ca2+ induced aggregation of nTiO2 and nAg NPs more strongly than K+ and Na+. Although K+ and Na+ had a similar effect on aggregation, K+ provided better screening of the particle surface charge presumably because of its small hydrated radius. These effects were decidedly more prominent for TiO2 than Ag. Anions (co-ions), SO42- and Cl-, affected the surface charge behavior of nTiO2 but not of nAg NPs. The zeta potential (ZP) of nTiO2 NPs was more negative at higher SO42-/Cl- ratios than lower. When Mg2+ was the counterion, charge inversion and rapid aggregation of nC60 NPs occurred under alkaline conditions, with a more pronounced effect for Cl- than SO42-. Response dissimilarities suggest fundamental differences in the interfacial-interaction characteristics of these NPs in the aquatic environment with corresponding differences in transport of these particles. Our study also shows the important role played by the iso-electric point pH (pHiep) of the NPs in determining their aggregation kinetics in the environment.

An alternative separation process integrating vapor stripping with a vapor compression step and a vapor permeation membrane separation step, termed membrane assisted vapor stripping (MAVS), has been proposed. The hydrophilic membrane separates the ethanol-water vapor into water-rich permeate and ethanol-enriched retentate vapor streams from which latent and sensible heat can be recovered. The objective of this work was to demonstrate experimentally the performance of a MAVS system and to compare the observed performance with chemical process simulation results using a 5 wt% ethanol aqueous feed stream as the benchmark. RESULTS: Performance of the steam stripping column alone was consistent with chemical process simulations of a stripping tower with six stages of vapor liquid equilibria (VLE). The overhead vapor from the stripper contained about 40 wt% ethanol and required 6.0 MJ of fuel-equivalent energy per kg of ethanol recovered in the concentrate. Introduction of the vapor compressor and membrane separation unit and recovery of heat from both membrane permeate and retentate streams resulted in a retentate ethanol concentrate containing ca 80 wt% ethanol, but requiring only 2.2 MJ fuel kg-1 ethanol, significantly less than steam stripping alone. CONCLUSION: Performance of the experimental unit with a 5 wt% ethanol feed liquid corroborated chemical process simulation predictions for the energy requirement of the MAVS system, demonstrating a 63% reduction in the fuel-equivalent energy requirement for MAVS compared with conventional steam stripping or distillation.

The crop area distributions and changes in crop rotations were characterized by comparing annual crop map products for 2005, 2006, and 2007. The total acreages for corn and soybeans were relatively balanced for calendar years 2005 (31,462 km super(2 and 31,283 km) super(2), respectively) and 2006 (30,766 km super(2 and 30,972 km) super(2), respectively). Conversely, corn acreage increased approximately 21% from 2006 to 2007, while soybean and wheat acreage decreased approximately 9% and 21%, respectively. Two-year crop rotational change analyses were conducted for the 2005-2006 and 2006-2007 time periods. The large increase in corn acreages for 2007 introduced crop rotation changes across the GLB. Compared to 2005-2006, crop rotation patterns for 2006-2007 resulted in increased corn-corn, soybean-corn, and wheat-corn rotations. The increased corn acreages could have potential negative impacts on nutrient loadings, pesticide exposures, and sediment-mediated habitat degradation. Increased in US corn acreages in 2007 were related to new biofuel mandates, while Canadian increases were attributed to higher world-wide corn prices. Additional study is needed to determine the potential impacts of increases in corn-based ethanol agricultural production on watershed ecosystems and receiving waters.

This paper explores the role of logjams as important agents of channel:floodplain interaction. We draw on a specific case study as well as examples from the literature to show that although the processes of interaction differ, the resulting dynamic floodplain patchwork is a common feature of rivers with logjams. In addition, we contend that the presence of logjams is an important factor in the evolution and maintenance of multiple channel patterns in both montane and lowland river environments. These observations have important implications for the definition of reference targets for river restoration. The specific results of this research show: 1) The presence of a range of types of multiple channel network dissecting the floodplains of low order channels that are strongly associated with the presence of logjams. 2) The relatively rapid formation of floodplain channels following logjam formation. 3) The dynamic nature of logjams within headwater channels on both seasonal and annual timescales that lead to a highly dynamic habitat mosaic on the floodplain surface. 4) An increased frequency of overbank flooding and high rates of floodplain sediment accumulation upstream of logjams and along floodplain channel networks that create the complex topography observed in the case study forested floodplains.

It has been demonstrated that chemical extractability of Cd is persistently decreased in biosolids-amended soils. This study was conducted to determine if Cd phytoavailability in long-term biosolids-amended soils was also persistently decreased. Paired control and biosolids-amended soils were collected from three experimental sites where large cumulative rates of biosolids were applied about 20 yr ago. The pH of all soils [in 0.01 mol L (super -1) Ca(NO (sub 3) ) (sub 2) ] was adjusted to 6.5+ or -0.2. Increasing rates of Cd-nitrate (from 0 to 10.0 mg Cd kg (super -1) soil) enriched in (super 111) Cd stable isotope were added to all soils, and Romaine lettuce (Lactuca sativa L. var. longifolia Lam.) was grown in pots to bioassay phytoavailable Cd. After harvest, Cd concentrations in shoots and labile pool of Cd (Cd (sub L) ) in soils were determined. The relationship between added salt-Cd and Cd concentrations in lettuce shoots was linear for all soils tested. Ratios of (shoot Cd):(soil Cd) slopes were highest in the control soils. Biosolids amendment decreased (shoot Cd):(soil Cd) slopes to varied extent depending on biosolids source, properties, and application rate. The decrease in slope in comparison to the control was an indication of the lower phytoavailability of Cd in biosolids-amended soils. A significant negative correlation existed between Cd uptake slopes and soil organic matter, free and amorphous Fe and Al oxides, Bray-P, and soil and plant Zn. Biosolids-Cd was highly labile (%L 80-95) except for Fulton County soil (%L=61).

Among the most commonly used recreation demand models are site choice models based on the multinomial logit framework, which account for the spatial relationships between each recreator's home and multiple alternative destinations thereby capturing the substitution possibilities among recreation sites. However, standard applications of this framework typically do not account for the possibility of spatial connections among the sites via movements of the target species, such as fish in connected water bodies in recreational angling applications or terrestrial species in hunting or wildlife viewing applications. In this paper we examine aspects of environmental valuation and natural resource dynamics that generally are addressed separately. Specifically, we show that in such spatially connected systems, a "reduced form" application of the standard site choice modeling approach, using proxy measures of environmental quality rather than direct measures of species abundances, can produce biased estimates of willingness to pay for environmental improvements. Furthermore, we show that under some conditions poorly targeted environmental improvements in spatially connected systems can lead to welfare decreases. In such systems a structural model of recreator site choices and species sorting behavior and population dynamics may be required to fully account for the spatial linkages among sites and the feedback effects between recreators and the target species.

To this end, we are conducting studies with mixtures of chemicals to elucidate mechanisms of joint action at the systemic level with the goal of providing a framework for assessing the cumulative effects of reproductive toxicants. Previous mixture studies conducted with antiandrogenic chemicals are reviewed briefly and two new studies are described. In all binary mixture studies, rats were dosed during pregnancy with chemicals, singly or in pairs, at dosage levels equivalent to approximately one-half of the ED50 for hypospadias or epididymal agenesis. The binary mixtures included androgen receptor (AR) antagonists (vinclozolin plus procymidone), phthalate esters [di(n-butyl) phthalate (DBP) plus benzyl n-butyl phthalate (BBP) and diethyl hexyl phthalate (DEHP) plus DBP], a phthalate ester plus an AR antagonist (DBP plus procymidone), a mixed mechanism androgen signalling disruptor (linuron) plus BBP, and two chemicals which disrupt epididymal differentiation through entirely different toxicity pathways: DBP (AR pathway) plus 2,3,7,8 TCDD (AhR pathway). We also conducted multi-component mixture studies combining several 'antiandrogens'. In the first study, seven chemicals (four pesticides and three phthalates) that elicit antiandrogenic effects at two different sites in the androgen signalling pathway (i.e. AR antagonist or inhibition of androgen synthesis) were combined. In the second study, three additional phthalates were added to make a 10 chemical mixture. In both the binary mixture studies and the multi-component mixture studies, chemicals that targeted male reproductive tract development displayed cumulative effects that exceeded predictions based on a response-addition model and most often were in accordance with predictions based on dose-addition models. In summary, our results indicate that compounds that act by disparate mechanisms of toxicity to disrupt the dynamic interactions among the interconnected signalling pathways in differentiating tissues produce cumulative dose-additive effects, regardless of the mechanism or mode of action of the individual mixture component.

Using direct sample analysis and respirometric testing, anaerobic degradation was examined with (a) each compound as the sole organic carbon source and (b) each compound at a lower concentration (250Akg/L) and cellulose serving as the primary organic carbon source. The change in pharmaceutical concentration was determined following 7, 28, 56, and 112days of anaerobic incubation at 37AC. Only acetylsalicylic acid demonstrated significant degradation; the remaining compounds showed a mixture of degradation and abiotic removal mechanisms. Experimental results were compared with BIOWIN, an anaerobic degradation prediction model of the US Environmental Protection Agency. The BIOWIN model predicted anaerobic biodegradability of the compounds in the order: acetylsalicylic acid>metoprolol tartrate>ibuprofen>acetaminophen>17a-ethinylestradiol>pr ogesterone.

Four forms of iron (ferric sulfate, ferric chloride, ferric nitrate, ferrous sulfate) were amended separately to GAC. Following Fe amendment, MTBE was adsorbed to the GAC followed by multiple applications of H2O2. Fe retention in GAC was high (83.8-99.9%) and decreased in the following order, FeSO4.7H2O>Fe2(SO4) sub(3). 9H2O>Fe(NO3) sub(3) 9H2O>FeCl3. A correlation was established between the post-sorption aqueous MTBE concentrations and Fe on the GAC for all forms of Fe investigated indicating that Fe amendment interfered with MTBE adsorption. However, the mass of MTBE adsorbed to the GAC was minimally affected by Fe loading. Relative to ferric iron amendments to GAC, ferrous iron amendment resulted in lower residual iron in solution, greater Fe immobilization in the GAC, and less interference with MTBE adsorption. MTBE oxidation was Fe limited and no clear trend was established between the counter-ion (SO4 super(-2), Cl super(-), NO3 super(-)) of the ferric Fe amended to GAC and H2O2 reaction, MTBE adsorption, or MTBE oxidation, suggesting these processes are anion independent.

These physics parameterizations were developed for the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) and have been used extensively by the air quality modeling community, so there was a need based on several factors to extend these parameterizations to WRF. Simulations executed with the new WRF physics are compared with simulations produced with the MM5 and another WRF configuration with a focus on the replication of near-surface meteorological conditions and key planetary boundary layer features. The new physics in WRF is recommended for retrospective simulations, in particular, those used to drive air quality simulations. In the summer, the error of all variables analyzed was slightly lower across the domain in the WRF simulation that used the new physics than in the similar MM5 configuration. This simulation had an even lower error than the other more common WRF configuration. For the cold season case, the model simulation was not as accurate as the other simulations overall, but did well in terms of lower 2-m temperature error in the western part of the model domain (plains and Rocky Mountains) and most of the Northeast. Both MM5 and the other WRF configuration had lower errors across much of the southern and eastern United States in the winter. The 2-m water vapor mixing ratio and 10-m wind were generally well simulated by the new physics suite in WRF when contrasted with the other simulations and modeling studies. Simulated planetary boundary layer features were compared with both wind profiler and aircraft observations, and the new WRF physics results in a more precise wind and temperature structure not only in the stable boundary layer, but also within most of the convective boundary layer. These results suggest that the WRF performance is now at or above the level of MM5. It is thus recommended to drive future air quality applications.

The magnitude of the stress reflects not only the quantity of aliens present, but also the quality of their interactions with native ecosystems. We develop an Index of Alien Impact (IAI) to estimate the collective ecological impact of in situ alien species. IAI summarizes the frequency of occurrence and potential ecological impact (Invasiveness-Impact Score (I sub(i)) of individual alien species for all aliens present in a particular location or community type. A component metric, I sub(i), is based on ecological species traits (life history, ecological amplitude, and ability to alter ecosystem processes) that reflect mechanisms, which can increase impact to ecosystem structure and function. While I sub(i) is less complex than some other multi-metric rankings of alien impact, it compares well to these metrics and to qualitative judgments. IAI can be adapted for different ecological settings by modifying the set of species traits incorporated in I sub(i) to reflect properties likely to breach biotic and abiotic barriers or alter ecosystem function in a particular region or community type of interest. To demonstrate our approach, we created versions of IAI and I sub(i), applicable to the diverse streamside vegetation of a river basin (19,631km super(2)) spanning low-elevation arid to mesic montane habitats in eastern Oregon, USA. In this demonstration effort, we (1) evaluate relationships of IAI to metrics describing invasion level, and (2) illustrate the potential utility of IAI for prioritizing alien species management activities and informing restoration goals.

A growing body of evidence indicates that iron sulfides play an important role in degrading TCE in natural environments and in engineered systems designed for groundwater cleanup. In this study, we investigate transformation processes of iron sulfides and consequent impacts on TCE degradation using batch experimental techniques, transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray absorption spectroscopy (XAS). Our results show that mackinawite is highly reactive toward TCE and no detectable mineralogical changes were detected during the course of reaction. However, freeze-dried FeS transformed to a mixture of mackinawite and greigite during the freeze drying process, with further mineralogical changes during reaction with TCE to lepidocrocite, goethite and pyrite. Newly formed lepidocrocite is a transient phase, with conversion to goethite over time. TCE transformation kinetics show that freeze-dried FeS is 20-50 times less reactive in degrading TCE than non-freeze-dried FeS, and the TCE degradation rate increases with pH (from 5.4 to 8.3), possibly due to an increase of surface deprotonation or electron transfer at higher pH. Results suggest that freeze drying could cause FeS particle aggregation, decreased surface area and availability of reactive sites; it also could change FeS mineralogy and accelerate mineral transformation. These aspects could contribute to the lower reactivity of freeze-dried FeS toward TCE degradation. Modeling results show that FeS transformation in natural environments depends on specific biogeochemical conditions, and natural FeS transformation may affect mineral reactivity in a similar way as compared to the freeze drying process. Rapid transformation of FeS to FeS (sub 2) could significantly slow down TCE degradation in both natural and engineered systems.

AN - 733636896; 20039168 AB - Numerous methods exist for assessing the potential toxicity of sediments in aquatic systems. In this study, the results from 10-day bulk sediment toxicity test methods using Hyalella azteca and Chironomus tentans were compared to results from 96-h Pimephales promelas and Ceriodaphnia dubia renewed acute toxicity tests conducted using elutriate samples prepared from the same sediments. The goal of the study was to determine if the results from the elutriate tests were comparable to those obtained from the bulk sediment tests. Of the 25 samples analyzed, 16 were found to be toxic to at least one of the species tested, in either elutriate or bulk sediment tests. The C. tentans 10-day bulk sediment test was the most sensitive, with 12 sediment samples exhibiting toxicity to this species, whereas the H. azteca bulk sediment test and C. dubia 96-h elutriate test were the least sensitive, exhibiting toxicity in only 7 of the 25 sediments tested. The P. promelas elutriate test found 8 of the 25 sediments to be toxic. Based on the total number of sites found to show toxicity, results from testing indicate 96-h elutriate tests show a level of sensitivity comparable to 10-day bulk sediment tests in assessing toxicity quantitatively. However, the methods did not always find toxicity at the same sites, suggesting that the ability of elutriate tests to predict toxicity (quantitatively) is not statistically correlated with bulk sediment methods. This would indicate that a suite of toxicity test methods would provide the most complete measure of site condition; however, in circumstances where bulk sediment testing is not feasible, elutriate tests can provide a practical and credible alternative for toxicity assessment.

(wild celery). AN - 733636227; 19795158 AB - Accelerated eutrophication is common to many freshwater and marine environments and often co-occurs with the presence of anthropogenic chemicals. However, the toxic effects of common chemical stressors such as herbicides in the presence of elevated nutrients are not well understood for most aquatic flora, particularly vascular species. To provide insight, field-collected Vallisneria americana Michx. (wild celery) were sequentially exposed to three nutrient concentrations for 3 months and then to nominal 11 and 110 microg L(-1) atrazine for 96 h. Nutrient concentrations (combined NH(4)(+), NO(2)(-), NO(3)(-), PO(4)(-)) were based on ambient concentrations in the St. Johns River (FL) and ranged from 0.013 to 0.668 mg L(-1). Nutrient pretreatment potentiated the toxicity of atrazine as determined by chlorophyll fluorescence activity. Electron transport rates (ETR) were significantly less (48-59%) for plants pretreated with low and ambient nutrient levels in the presence of an average of 107.5-128.1 microg L(-1) atrazine. Significant ETR reductions were also observed for plants exposed to an average of 11.4 microg L(-1) atrazine after exposure to nutrients three times the ambient concentration in the St. Johns River. The results indicate the importance of considering the presence of nutrients in chemical hazard assessments, particularly for phytotoxicants and nontarget vascular plants.

AN - 733508932; 20175128 AB - Triadimefon, propiconazole, and myclobutanil are conazoles, an important class of agricultural fungicides. Triadimefon and propiconazole are mouse liver tumorigens, while myclobutanil is not. As part of a coordinated study to understand the molecular determinants of conazole tumorigenicity, we analyzed the microRNA expression levels in control and conazole-treated mice after 90 d of administration in feed. MicroRNAs (miRNAs) are small noncoding RNAs composed of approximately 19-24 nucleotides in length, and have been shown to interact with mRNA (usually 3' UTR) to suppress its expression. MicroRNAs play a key role in diverse biological processes, including development, cell proliferation, differentiation, and apoptosis. Groups of mice were fed either control diet or diet containing 1800 ppm triadimefon, 2500 ppm propiconazole, or 2000 ppm myclobutanil. MicroRNA was isolated from livers and analyzed using Superarray whole mouse genome miRNA PCR arrays from SABioscience. Data were analyzed using the significance analysis of microarrays (SAM) procedure. We identified those miRNAs whose expression was either increased or decreased relative to untreated controls with q < or = 0.01. The tumorigenic conazoles induced many more changes in miRNA expression than the nontumorigenic conazole. A group of 19 miRNAs was identified whose expression was significantly altered in both triadimefon- and propiconazole-treated animals but not in myclobutanil-treated animals. All but one of the altered miRNAs were downregulated compared to controls. This pattern of altered miRNA expression may represent a signature for tumorigenic conazole exposure in mouse liver after 90 d of treatment.

AN - 733117985; 20166807 AB - At some level, carboxyhemoglobin (COHb) due to inhalation of carbon monoxide (CO) reduces maximum exercise duration in both normal and ischemic heart patients. At high COHb levels in normal subjects, brain function is also affected and behavioral performance is impaired.These are findings from published experiments that are, due to ethical or practical considerations, incomplete in that higher or lower ranges of COHb, and exercise have not been well studied. To fill in this knowledge base, a whole-body human physiological model was used to make estimates of physiological functioning by the simulation of parametric exposures to CO and various exercise levels. Ischemic heart disease was simulated by introducing a stenosis in the left heart arterial supply. Brain blood flow was also limited by such a stenosis. To lend credibility to such estimation, the model was tested by simulating experiments from the published literature. Simulations permitted several new conclusions. Increases in COHb produced the largest decreases in exercise duration when exercise was least strenuous and when COHb was smallest. For ischemic heart disease subjects, the greatest change in exercise duration produced by COHb increase was when ischemia and COHb was smallest. Brain aerobic metabolism was unaffected until COHb exceeded 25%, unless the maximum brain blood supply was limited by a stenosis greater than 50% of normal. For higher levels of stenosis, aerobic brain metabolism was reduced for any increase in COHb level, implying that behavior would be impaired with no "threshold" for COHb.

Stainless steel, SilcosteelA+ and SulfinertA+ treated stainless steel tubes exhibited varying degrees of adsorption and reactivity towards some analytes. However, the typical short exposure of the sample stream to wall material before entering an adsorbent bed, minimizes the effect of these properties. Three forms of silica wool (untreated glass wool and siloxane-treated glass and fused silica wool), often used as adsorbent bed retainers, were evaluated and found to function as an adsorbent bed especially for oxygenated monoterpenes and sesquiterpenes. Tenax-TA was evaluated in stainless steel tubes (untreated and treated) with a 2 mu m mesh woven wire disk (also untreated and treated) to circumvent the effects of using a silica wool bed retainer. Tenax-TA adsorbent in stainless steel, Silcosteel and Sulfinert tubes yielded equivalent results when compared with direct (cryogenic) pre-concentration analysis of a multi-component mixture of n-alkanes and selected biogenic VOC. Tenax-TA tubes that had been used for 15-20 bake out-sample-desorption cycles (field and laboratory sampling) were compared with freshly packed tubes and found to give equivalent results.

This article focuses on how landfills are participating in voluntary carbon and renewable energy markets, and presents case studies from award-winning projects that utilize these funding mechanisms. Landfills participate in the voluntary carbon markets using one of two main mechanisms: on an exchange or through an over-the-counter (OTC) transaction. An exchange, such as the Chicago Climate Exchange (CCX), is likely the most well known mechanism. At present, CCX has 35 registered landfill methane offset project providers in the United States [1]. As of April 2008, landfill methane projects comprised approximately 9 percent of all the carbon credits issued by CCX. OTC transactions are private between the seller, buyer, and/or broker involved in the transaction. Despite their private nature, the volume of OTC traded emissions has substantially grown in recent years according to research from Ecosystem Marketplace [2]. Recent data from Point Carbon indicate that 132 U.S. landfills have either made a transaction in the carbon market, or are in the process of developing, producing, certifying, or verifying their emissions reductions to prepare for an OTC transaction or exchange on the CCX [3]. In addition to carbon finance, LFGE projects generating electricity are also selling renewable energy certificates (RECs). These RECs are then purchased by companies wishing to reduce their environmental footprint or used by utilities to comply with various renewable portfolio standards. Stakeholders are also using state and federal financial incentives to promote LFGE projects. In 2008, the IRS awarded 45 applicants the authority to issue Clean Renewable Energy Bonds (CREBs) to support LFGE projects [4]. Several other new financial incentives were funded under the American Recovery and Reinvestment Act of 2009 (ARRA) including the Energy Efficiency and Conservation Block Grants (EECBG) and extensions to the federal production tax credits. This article summarizes financial incentives available for LFGE projects and provides case study examples of several landfills that are implementing projects with these funds.

This study describes relationships among primary nutrients (phosphorus and nitrogen), benthic chlorophyll a concentrations, daily dissolved oxygen (DO) concentrations, and the condition of macroinvertebrate and fish communities in small rivers and streams in Ohio, USA. Clear associations between nutrients, secondary response indicators (i.e., benthic chlorophyll and DO), and biological condition were found, and change points between the various indicators were identified for use in water quality criteria for nutrients in small rivers and streams (<1300km super(2)). A change point in benthic chlorophyll a density was detected at an inorganic nitrogen concentration of 0.435mg/l (c0.599 SD), and a total phosphorus (TP) concentration of 0.038mg/l (c0.085 SD). Daily variation in DO concentration was significantly related to benthic chlorophyll concentration and canopy cover, and a change point in 24-h DO concentration range was detected at a benthic chlorophyll level of 182mg/m super(2). The condition of macroinvertebrate communities was related to benthic chlorophyll concentration and both minimum and 24-h range of DO concentration. The condition of fish communities was best explained by habitat quality. The thresholds found in relationships between the stressor and the response variables, when interpreted in light of the uncertainty surrounding individual change points, may now serve as a framework for nutrient criteria in water quality standards.

We estimated the toxicity of mixtures of chlorinated, brominated, and mixed bromochloro-dioxins and -furan (PBCDDs/Fs) laboratory standards using a chemically-activated luciferase gene expression cell bioassay (CALUX). The relative effects potency (REP) values obtained were comparable to the World Health Organization (WHO) toxic equivalency factors (TEFs) and in agreement with the concept of additive congener toxicity of mixtures of dioxins and furans. Enzyme immunoassay (EIA)-based toxic equivalents (TEQs), however, showed overestimation for PCDDs/Fs (0-4 orders of magnitudes higher) and underestimation for PBDDs/Fs (0-1 orders of magnitude lower) when compared to high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS)-based TEQ calculation (using WHO TEFs) in samples from an industrial source line. No correlation was found between the EIA and the HRGC/HRMS data, which could be attributed to differences in homologue-specific cross-reactivity responses, sample matrix type, and presence of other compounds competing for antibody binding in the immunoassay.

At sites in Virginia (one coastal and one Piedmont), lowland forested wetlands separate upland fields from nearby surface waters (an estuary and a stream). At the coastal site, nitrate concentrations near the water table decreased from more than 10 mg/l beneath fields to 2 mg/l beneath a riparian forest buffer because recharge through the buffer forced water with concentrations greater than 5 mg/l to flow deeper beneath the buffer. Diurnal changes in groundwater levels up to 0.25 meters at the coastal site reflect flow from the water table into unsaturated soil where roots remove water and nitrate dissolved in it. Decreases in aquifer thickness caused by declines in the water table and decreases in horizontal hydraulic gradients from the uplands to the wetlands indicate that more than 95% of the groundwater discharged to the wetlands. Such discharge through organic soil can reduce nitrate concentrations by denitrification. Model simulations are consistent with field results, showing downward flow approaching toe slopes and surface waters to which groundwater discharges. These effects show the importance of buffer placement over use of fixed-width, streamside buffers to control nitrate concentrations. Abstract Copyright (2010), American Water Resources Association.

We focused on groundwater denitrification capacity, water table dynamics, and the presence and pattern of organically enriched deposits. We used the push-pull method (measurement of (super 15) N-enriched denitrification gases derived from an introduced groundwater plume of (super 15) N-enriched nitrate) to evaluate groundwater denitrification capacity on nine forested wetland riparian sites developed in alluvial or outwash parent materials in southern New England. Three replicate sites were located in each of the three watershed types, those with substantial (1) irrigated agriculture, (2) suburban development, and (3) forest. Soil morphology and water table dynamics were assessed at each site. We found significantly lower mean annual water tables at sites within watersheds with substantial irrigated agriculture or suburban development than forested watersheds. Water table dynamics were more variable at sites within suburban watersheds, especially during the summer. Groundwater denitrification capacity was significantly greater at sites within forested watersheds than in watersheds with substantial irrigated agriculture. Because of the high degree of variability observed in riparian sites within suburban watersheds, groundwater denitrification capacity was not significantly different from either forested or agricultural watersheds. The highly variable patterns of organically enriched deposits and water tables at sites within suburban watersheds suggests that depositional events are irregular, limiting the predictability of groundwater N dynamics in these riparian zones. The variability of riparian N removal in watersheds with extensive suburbia or irrigated agriculture argues for N management strategies emphasizing effective N source controls in these settings.

In this study, the impact of the 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 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 show that overall none of the mechanisms performs systematically better than the others. On the other hand, at the AIRNow surface sites, 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%) for observed O sub(3).75 ppb, whereas CB4 has the best performance with the least overestimation for 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) mixing ratios 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 southwesterly/westerly offshore flows. The results of the O sub(3)-NO sub(z) slopes over the ocean indicate that SAPRC-99 has the highest upper limits of the ozone production efficiency (e 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 JF - Atmospheric Chemistry and Physics AU - Yu, S AU - Mathur, R AU - Sarwar, G AU - Kang, D AU - Tong, D AU - Pouliot, G AU - Pleim, J AD - Atmospheric Modeling and Analysis Division, National Exposure Research Laboratory, US Environmental Protection Agency, Research Triangle Park, NC 27711, USA Y1 - 2010/03/30/ PY - 2010 DA - 2010 Mar 30 SP - 3001 EP - 3025 PB - European Geophysical Society, Max-Planck-Str. 13 Katlenburg-Lindau Germany VL - 10 IS - 6 SN - 1680-7316, 1680-7316 KW - Aqualine Abstracts;

Recent ecosystem-scale measurements indicate that a fraction of recently deposited mercury is recycled back into the atmosphere quickly, and that an atmospheric compensation point exists at background ambient concentrations. Modeled Hg0 emissions from natural sources are typically uncoupled from dry deposition estimates and unconstrained by air-biosphere gradient processes. A module has been developed for the Community Multiscale Air Quality (CMAQ) model to parameterize concentration-dependent processes of bidirectional mercury exchange. The Hg0 air-surface exchange was modeled as a function of a dynamic compensation point. The compensation point is modeled as a function of sources and sinks of Hg0 in vegetation and soil media using partitioning coefficients. A box model simulation was run for five months and a CMAQ simulation with bidirectional (BIDI) and without bidirectional (BASE) mercury exchange was run for the month of July 2002. The BASE case modeling scenario estimated that 8.5% of the total mercury (Hg0 + Hg2 + PHg) deposited to terrestrial systems and 47.8% of the total mercury deposition to aquatic systems was re-emitted as Hg0, while the re-emission ratios were 70.4% and 52.5% in the base case. The BIDI case was in better agreement with recent estimates of mercury cycling using stable isotopic mass balance experiments. JF - Journal of Geophysical Research.

The processing, use, and transport of the ore, which was contaminated with amphibole asbestos, led to generalized contamination of the community. The mine closed in 1990. We examined the prevalence of respiratory symptoms in 2000-2001 and their association with history of vermiculite exposure among people who were , 18 years of age when the mine closed. Information on respiratory symptoms and exposure history was collected by questionnaire in 2000-2001, at which time participants were 10-29 years old. Logistic regression was used to model the associations between exposures and outcomes adjusted for age, sex, and tobacco smoke exposure. Of the 1,003 individuals included in the study, 10.8% reported usually having a cough, 14.5% reported experiencing shortness of breath when walking up a slight hill or hurrying on level ground, and 5.9% reported having coughed up bloody phlegm in the past year. These respiratory symptoms were positively associated with frequently handling vermiculite insulation compared with never handling vermiculite insulation. We found no association between vermiculite insulation in the house and respiratory symptoms. Respiratory symptoms were associated with other vermiculite exposures as well, and the number and frequency of these activities showed a positive trend with usually having a cough. We found no association between any of the activities and abnormal spirometry. These data suggest that residents of Libby, Montana, who were children when the mine closed experienced some respiratory symptoms associated with asbestos-contaminated vermiculite exposure.

The main elements of green infrastructure are hubs and links. Hubs tend to be large areas of natural vegetation and links tend to be linear features (e.g., streams) that connect hubs. Within the United States, green infrastructure projects can be characterized as: (1) reliant on classical geographic information system (GIS) techniques (e.g., overlay, buffering) for mapping; (2), mainly implemented by states and local jurisdictions; and (3) static assessments that do not routinely incorporate information on land-cover change. We introduce morphological spatial pattern analysis (MSPA) as a complementary way to map green infrastructure, extend the geographic scope to the conterminous United States, and incorporate land-cover change information. MSPA applies a series of image processing routines to a raster land-cover map to identify hubs, links, and related structural classes of land cover. We identified approximately 4000 large networks (>100 hubs) within the conterminous United States, of which approximately 10% crossed state boundaries. We also identified a net loss of up to 3.59 million ha of links and 1.72 million ha of hubs between 1992 and 2001. Our national assessment provides a backbone that states could use to coordinate their green infrastructure projects, and our incorporation of change illustrates the importance of land-cover dynamics for green infrastructure planning and assessment.

AN - 733472598; 20143881 AB - Exposure to environmental chemicals adds to the burden of disease in humans and wildlife to a degree that is difficult to estimate and, thus, mitigate. The ability to assess the impact of existing chemicals for which little to no toxicity data are available or to foresee such effects during early stages of chemical development and use, and before potential exposure occurs, is a pressing need. However, the capacity of the current toxicity evaluation approaches to meet this demand is limited by low throughput and high costs. In the context of EPA's ToxCast project, we have evaluated a novel cellular biosensor system (Factorial (1) ) that enables rapid, high-content assessment of a compound's impact on gene regulatory networks. The Factorial biosensors combined libraries of cis- and trans-regulated transcription factor reporter constructs with a highly homogeneous method of detection enabling simultaneous evaluation of multiplexed transcription factor activities. Here, we demonstrate the application of the technology toward determining bioactivity profiles by quantitatively evaluating the effects of 309 environmental chemicals on 25 nuclear receptors and 48 transcription factor response elements. We demonstrate coherent transcription factor activity across nuclear receptors and their response elements and that Nrf2 activity, a marker of oxidative stress, is highly correlated to the overall promiscuity of a chemical. Additionally, as part of the ToxCast program, we identify molecular targets that associate with in vivo end points and represent modes of action that can serve as potential toxicity pathway biomarkers and inputs for predictive modeling of in vivo toxicity.

Moreover, the answers are not always positive. In particular some postprocessing method is competitive or superior to human forecast. Within the alert system of ARPA Piemonte it is possible to study in an objective manner if the human forecaster is able to add value with respect to computer-generated forecasts. Every day the meteorology group of the Centro Funzionale of Regione Piemonte produces the HQPF (Human Quantitative Precipitation Forecast) in terms of an areal average and maximum value for each of the 13 warning areas, which have been created according to meteo-hydrological criteria. This allows the decision makers to produce an evaluation of the expected effects by comparing these HQPFs with predefined rainfall thresholds. Another important ingredient in this study is the very dense non-GTS (Global Telecommunication System) network of rain gauges available that makes possible a high resolution verification. In this work we compare the performances of the latest three years of QPF derived from the meteorological models COSMO-I7 (the Italian version of the COSMO Model, a mesoscale model developed in the framework of the COSMO Consortium) and IFS (the ECMWF global model) with the HQPF. In this analysis it is possible to introduce the hypothesis test developed by Hamill (1999), in which a confidence interval is calculated with the bootstrap method in order to establish the real difference between the skill scores of two competitive forecasts. It is important to underline that the conclusions refer to the analysis of the Piemonte operational alert system, so they cannot be directly taken as universally true. But we think that some of the main lessons that can be derived from this study could be useful for the meteorological community. In details, the main conclusions are the following: - despite the overall improvement in global scale and the fact that the resolution of the limited area models has increased considerably over recent years, the QPF produced by the meteorological models involved in this study has not improved enough to allow its direct use: the subjective HQPF continues to offer the best performance for the period +24 h/+48 h (i.e. the warning period in the Piemonte system); - in the forecast process, the step where humans have the largest added value with respect to mathematical models, is the communication. In fact the human characterization and communication of the forecast uncertainty to end users cannot be replaced by any computer code; - eventually, although there is no novelty in this study, we would like to show that the correct application of appropriated statistical techniques permits a better definition and quantification of the errors and, mostly important, allows a correct (unbiased) communication between forecasters and decision makers.

AN - 733116989; 20095644 AB - We have performed for the first time a comprehensive profiling of changes in protein expression of soluble proteins in livers from mice treated with the mouse liver tumorigen, propiconazole, to uncover the pathways and networks altered by this fungicide. Utilizing two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS), we identified 62 proteins that were altered. Several of these protein changes detected by 2-DE/MS were verified by Western blot analyses. These differentially expressed proteins were mapped using Ingenuity Pathway Analyses (IPA) canonical pathways and IPA tox lists. Forty-four pathways/lists were identified. IPA was also used to create networks of interacting protein clusters. The protein-generated IPA canonical pathways and IPA tox lists were compared to those pathways and lists previously generated from genomic analyses from livers of mice treated with propiconazole under the same experimental conditions. There was a significant overlap in the specific pathways and lists generated from the proteomic and the genomic data with 27 pathways common to both proteomic and genomic analyses. However, there were also 17 pathways/lists identified only by proteomics analysis and 21 pathways/lists only identified by genomic analysis. The protein network analysis produced interacting subnetworks centered around hepatocyte nuclear factor 4 alpha (HNF4 alpha), MYC, proteasome subunit type 4 alpha, and glutathione S-transferase (GST). The HNF4 alpha network hub was also identified by genomic analysis. Five GST isoforms were identified by proteomic analysis and GSTs were present in 10 of the 44 protein-based pathways/lists. Hepatic GST activities were compared between mice treated with propiconazole and 2 additional conazoles and higher GST activities were found to be associated with the tumorigenic conazoles. Overall, this comparative proteomic and genomic study has revealed a series of alterations in livers induced by propiconazole: nuclear receptor activation, metabolism of xenobiotics, metabolism of biochemical intermediates, biosynthesis of biochemical intermediates, and oxidative stress in mouse liver. The present study provides novel insights into toxic mechanisms and/or modes of action of propiconazole which are required for human health risk assessment of this environmental chemical.

Data were compiled from three surveys conducted in Santa Rosa Sound, located in northwest Florida, at three different meadows in sequential years. Biomass measurements and leaf growth rates decreased between stations along transects from shallow to deeper water. Belowground biomass weights decreased and leaf C:P ratios increased with temperature reflecting a seasonal growth pattern. The T. testudinum parameters were highly correlated with each other. Sulfate reduction rates (at times exceeding 1000 nmol ml-1 day-1) were among the highest recorded for seagrass beds with temperature accounting for 79% of the variation. Even though sulfate reduction rates were high, total Fe:reduced S ratios indicated sufficient Fe to account for all reduced S as pyrite. Sediment Fe, C, N, and organic P concentrations increased with sediment depth, whereas inorganic P decreased with depth, suggesting burial of organic P and root uptake of inorganic P. Leaf C:N:P ratios indicated P-limited growth for two surveys. NH4 + was detected in water above the sediment surface during some surveys demonstrating T. testudinum meadows at times may serve as sources of inorganic N to the water column. Plant parameters correlated with concentrations of sediment organic C and N, Fe, S, and porewater NH4 +. These results highlight the importance of the organic matter and Fe contents of sediments to seagrass growth.

The use of physiologically based pharmacokinetic (PBPK) models to better describe chemical exposure is made more powerful by incorporation of high quality in vitro kinetic data. To this end, metabolism of the conazole fungicide triadimefon was studied in hepatic microsomes of both genders of SD rats and CD-1 mice. Triadimefon depletion and triadimenol formation were measured in each type of microsomes. Michaelis-Menten regressions were applied to metabolic data and V MAX and the Michaelis constant (K M) values calculated. Male SD rats metabolized triadimefon more rapidly than female SD rats or either gender of CD-1 mouse. K M values were in the micromolar range, indicating the possibility of competitive inhibition with endogenous substrates. Intrinsic clearances derived from kinetic parameters indicate that triadimefon metabolism is blood-flow limited in all organisms studied with the possible exception of female rat. The in vitro half-life method was investigated as a less resource intensive method for the derivation of intrinsic clearance, and was found to be useful as a complement to the traditional Michaelis-Menten approach.

Limited information on the exposure to nanomaterials is available, with only a few occupational exposure studies having been performed. While laboratory animal studies on the biological effects of some nanomaterials have been published, no epidemiological studies have been reported to date. This lack of data on exposure and human health effects hinders risk assessment of these materials. As the use of nanomaterials increases rapidly, it is of vital importance that the risk assessment community understands the complexities of the issues surrounding the manufacture, use and disposal of nanomaterials, the potential of environmental and occupational exposure to human populations, as well as adverse health outcomes. For this to happen, it is in many ways necessary for the scientific community to also understand what questions risk assessors need to ask, and what research will best answer them. Risk management of nanomaterials requires more information as to the human and ecological effects of exposure to various nanomaterials. At this time, there are no specific regulations for nanomaterials, but a few efforts to include nanomaterials under existing environmental regulations have begun. The purpose of this article is to describe the potential regulations for nanomaterials, and the current issues related to the risk assessment of nanomaterials.

At sufficiently high contaminant levels, sediments can cause toxicity to aquatic organisms and impair benthic communities. As a result, remediation is necessary and diagnosing the cause of sediment toxicity becomes imperative. In the present study, six sediments from a highly industrialized area in Patrick Bayou (TX, USA) were subjected to initial toxicity testing with the mysid, Americamysis bahia, and the amphipod, Ampelisca abdita. All sediments were toxic to the amphipods, while sites PB4A, PB6A, and PB9 were the only sites toxic to mysids. Due to its toxicity to both test organisms, site PB6A was chosen for a marine whole sediment phase I toxicity identification evaluation (TIE). Results of the TIE found toxicity to amphipods was primarily due to nonionic organic contaminants (NOCs), rather than cationic metals or ammonia. Causes of mysid toxicity in the TIE were less clear. An assessment of metal bioavailability using equilibrium partitioning (EqP) approaches supported the results of the TIE that cationic metals were not responsible for observed toxicity in PB6A for either organism. Toxic units (TU) calculated on measured concentrations of NOCs in the sediment yielded a total TU of 1.25, indicating these contaminants are contributing to the observed sediment toxicity. Using a combination of these TIE and EqP assessment tools, this investigation was capable of identifying NOCs as the likely class of contaminants causing acute toxicity to amphipods exposed to Patrick Bayou sediment. The cause of mysid toxicity was not definitively determined, but unmeasured NOCs are suspected.

New approaches in biological and computational sciences may be able to generate mechanistic information that could help in meeting these challenges. However, to use mechanistic data to support chemical assessments, there is a need for effective translation of this information into endpoints meaningful to ecological risk-effects on survival, development, and reproduction in individual organisms and, by extension, impacts on populations. Here we discuss a framework designed for this purpose, the adverse outcome pathway (AOP). An AOP is a conceptual construct that portrays existing knowledge concerning the linkage between a direct molecular initiating event and an adverse outcome at a biological level of organization relevant to risk assessment. The practical utility of AOPs for ecological risk assessment of chemicals is illustrated using five case examples. The examples demonstrate how the AOP concept can focus toxicity testing in terms of species and endpoint selection, enhance across-chemical extrapolation, and support prediction of mixture effects. The examples also show how AOPs facilitate use of molecular or biochemical endpoints (sometimes referred to as biomarkers) for forecasting chemical impacts on individuals and populations. In the concluding sections of the paper, we discuss how AOPs can help to guide research that supports chemical risk assessments and advocate for the incorporation of this approach into a broader systems biology framework.

Headwater mayfly assemblages were evaluated with respect to regional landuse disturbances (coal mining and residential) in eastern Kentucky, USA. Estimates of mayfly taxa richness and relative abundance were compared at 92 sites represented by least-disturbed reference (REF; n=44), residential only (RESID; n=14), mixed residential and mining (MINED/RESID; n=14), and mining only (MINED; n=20) landuse categories. A total of 48 species from 27 genera and 9 families were identified; Ephemerella, Epeorus, Ameletus, Cinygmula, and Paraleptophlebia comprised the core 5 genera most frequently encountered at REF sites. These same genera (among others) were often reduced or extirpated from other landuse categories. Mean mayfly richness and relative abundance were significantly higher at REF sites compared to all other categories; MINED sites had significantly lower metric values compared to RESID and MINED/RESID sites. Relative mayfly abundance was most strongly correlated to specific conductance (r=0.72) compared to total habitat score (r=0.59), but relationships varied depending on landuse category. Non-metric multidimensional scaling (for mayfly taxa) and principal components analysis (for environmental variables) separated REF sites strongly from most other sites. The results indicate that expected mayfly communities are disappearing from streams where mining disturbance and residential development has occurred and because of the long-term impacts incurred by both landuses, recovery is uncertain.

As the primary directive moved from aiding fishermen in expanding their operations emphasizing conservation, the government over time recognized that management involves influencing people not fish, and has hired social scientists to complement the biologists who assess fish populations. This change has not always been smooth. We use archival documents and oral histories to trace the development of sociocultural analytic capabilities within NMFS and describe future plans for growing the program. Four points are made. First, NMFS has created the best developed social science program in NOAA. Second, established institutions change slowly; achieving the social science presence in NMFS has taken over 25 years. Third, change needs visionaries and champions with both tenacity and opportunity. Fourth, social science data collection and research helps in making fishery management decisions, but they have also been useful in evaluating the impact and helping with the recovery from Hurricane Katrina. Good work finds other uses.

Euhedral arsenopyrite grains are found with ilmenite, apatite, and REE phosphates in zones that generally mimic the intersection between a gneissic fabric and a relict magmatic foliation. Arsenopyrite crystals are typically elongate with this lineation. Euhedral to subhedral pyrite crystals have also been observed, but are localized to areas without As-bearing phases. Micro-fractures that parallel either a steep NW-striking joint set or gently-dipping sheeting joints are commonly filled with interwoven calcite cements and As-bearing Fe-oxides. Surface coatings of major fracture sets are also characterized by Fe-As-rich rinds that host micron-scale sub-angular particles of quartz, feldspars, and phyllosilicates. Where micro-fractures are most concentrated, sulfide-bearing minerals are less common; however, subhedral to anhedral arsenopyrite grains do occur along some open micro-fractures. These crystals preserve lobate grain boundaries and are associated with As-bearing Fe-oxide-rich coatings along adjacent fractures. The presence of 1) pyrite, 2) arsenopyrite associated with phosphates, and 3) As-bearing fracture coatings suggests multiple stages of mineralization. We propose that intrusion-related fluid-rock interaction associated with heating of nearby sulfide-bearing schists of the Berwick Formation during Acadian orogenesis may have provided the necessary constituents for growth of sulfide phases in the Ayer. It appears that Late Devonian greenschist facies metamorphism and metasomatism led to mineralization that generated arsenopyrite and accompanying phosphates; however, the role of the cross-cutting Clinton Newbury Fault Zone as a conduit for hydrothermal fluids may also be important. Lower temperature As-bearing Fe-oxide and calcite coatings on open fractures surfaces may be associated with a change from lithostatic- to hydrostatic-pressures during post-glacial regional uplift. This mineralization appears to be synchronous with intense microfracturing that post-dates all other mineralization.

We now know that for most locations atmospheric deposition is the dominant mercury source, and that mercury methylation is the key process that translates low mercury loading rates into relatively high levels in top predators of aquatic food webs. Despite significant advances in our understanding of the controlling processes, and national-scale image of relative contamination levels has remained elusive. As such, resource managers and public health officials have limited options for informing the public on of where elevated mercury concentrations in sport fish are more likely to occur than others. This project provides, for the first time, a national map of predicted (modeled) methylmercury concentrations in surface waters. The map shows clear regional trends. East of the Mississippi, the Gulf and southeastern Atlantic coasts, the northeast, the lower Mississippi Valley, and Great Lakes area are predicted to have generally higher environmental methylmercury levels. Higher-elevation, well-drained areas of Appalachia are predicted to have relatively lower methylmercury abundance. Other than the prairie pothole region, in the Western US incessant regional patterns are less clear. However, the full range of predicted methylmercury levels is predicted to occur in Western US watersheds. Lastly, although this map is being presented at the continental US scale, the principles used to generate the modeled results can easily applied to data sets that represent ranges (local to global) in geographic scales.

The purpose of this study is to utilize the sediment record of Conroy Lake to reconstruct environmental variability in the lake during the late Holocene, specifically with regard to organic carbon deposition. During the summer of 2009, a modified Kullenberg corer was used to obtain a sediment core from the deep hole of the lake (CL09KC1, l=239.7cm; z=35m). This core was split, and a multiproxy approach was used to interpret the environmental history of the lake. Loss on ignition analyses were used to obtain records of dry/wet bulk density, organic carbon (LOI at 550 degrees C), and carbonate content (LOI at 1000 degrees C). Magnetic susceptibility and image analysis (i.e. RGB) were used to corroborate with organic carbon variability. Loss on ignition results have shown that organic carbon percentages through the core ranged from 15% to 23% throughout the 240cm core, with a gradually increasing trend from 239-82cm (range 15.6%-18.7%), increasing rapidly from 82-44cm (range 16.6%-22.5%), followed by an decreasing trend for the remaining 44-0cm (range 22.5%-17%). Image analysis displays high frequency variability interpreted to represent the laminated nature of sediment. An apparent negative correlation is noted between organic carbon and the green spectrum, suggesting that the RGB data may provide a higher-resolution record of organic matter deposition than the LOI can afford. Magnetic susceptibility results ranged from -.05 to 5.5 SI units, with noticeable peaks at or near vivianite layers. A slight positive correlation between magnetic susceptibility and organic content suggests a common control over magnetic input and organic matter input to the sediment. One possible explanation of this observation may involve the role of magnetotactic bacteria in the water column. Ongoing work is utilizing carbon and nitrogen stable isotope ratios, as well as carbon/nitrogen elemental ratios, to determine the origin of the organic matter preserved in the sediment. In addition, pending radiocarbon dates from terrestrial macrofossils are expected to provide age constraints to the variability observed.

The emissions test locations included a coal-fired utility boiler (CFUB) that typically uses low sulfur (<0.7%) Eastern bituminous coal as a fuel source, whereas the oil-fired utility boiler (OFUB) uses number 6 residual oil containing 2.4 % sulfur. From both facilities co-located sets of fine fraction (<2.5 mm mass median aerodynamic diameter) particulate matter samples were acquired over a period of several days using a dilution sampler system (DSS) from stack sampling ports at a location of approximately 40 meters above the ground surface. The DSS is designed to dilute stack emissions with clean ambient air (1:35), and then allows sufficient residence time at near-ambient temperature and pressure conditions to promote condensation and coagulation of particulate matter. The PM (sub 2.5) total metal concentrations were determined using energy dispersive X-ray fluorescence (ED-XRF). Subsequently the results from leaching experiments, designed to yield water and dilute acid extractable metal concentrations, were quantified using high resolution inductively coupled plasma mass spectrometry (HR-ICPMS). In general, the total amount of metals emitted from CFUB was greater than that emitted from the OFUB, but the water soluble fraction of the metals from the OFUB was higher than from the CFUB. In combination, these total concentration as well as solubility based trace element profiles will provide new insights from source apportionment, ecosystem impact and human health perspectives.

The sites represented five unique river reaches--impounded and unimpounded reaches of the Upper Mississippi River, the upper and lower reaches of the Missouri River, and the entire Ohio River. Land use and river chemistry varied significantly between rivers and reaches. There was more agriculture in the two Upper Mississippi River reaches, and this was reflected in higher nutrient concentrations at sites in these reaches. EEA was highest in the two Upper Mississippi River reaches, followed by the lower Missouri River reach. EEA was generally lowest in the upper Missouri River reach. Canonical correlation analysis revealed a strong correlation between EEA and the suite of water and sediment chemistry variables, and the percent of the catchment in anthropogenically dominated land uses, including agriculture and urban development. Nutrient ratios of the waters and sediments suggested carbon (C), nitrogen (N), or phosphorus (P) limitation at a large number of sites in each reach. C-limitation was most pronounced in the unimpounded Mississippi River and lower Missouri River reaches; N-limitation was prevalent in the two Missouri River reaches; and P-limitation dominated the Ohio River. Linking microbial enzyme activities to regional-scale anthropogenic stressors in these large river ecosystems suggests that microbial enzyme regulation of carbon and nutrient dynamics may be sensitive indicators of anthropogenic nutrient and carbon loading.

The large tidal range (2-3 m) in this region exposes most of this seagrass community at low tide, permitting the use of false colour near-infrared film that provides good contrast in imaging vegetated intertidal habitats. Three Oregon coastal estuaries in the USA were surveyed in 2004 or 2005 at photoscales of 1:10 000 or 1:20 000. Spatial resolution was 0.25 m and the minimum mapping unit was 2.5 t 2.5 m. Spatial accuracy was within 1.5 m. Comparison of the image classification and ground survey results yielded overall classification accuracies of 83% to 97%. This appears to be an effective technique for mapping intertidal eelgrass distributions in turbid coastal estuaries with large tidal ranges.

Uncertainty was calculated for budget terms by propagating the standard error and degrees of freedom. New aspects include the combined use of Monte Carlo simulations with classical error propagation methods, uncertainty analyses for GIS computations, and uncertainty propagation involving literature and subjective estimates of terms used in the budget calculations. The methods employed are broadly applicable to the mathematical operations employed in ecological studies involving step-by-step calculations, scaling procedures, and calculations of variables from direct measurements and/or literature estimates. Propagation of the standard error and the degrees of freedom allowed for calculation of the uncertainty intervals around every term in the budget. For scientists and environmental managers, the methods developed herein provide a relatively simple framework to propagate and assess the contributions of uncertainty in directly measured and literature estimated variables to calculated variables. Application of these methods to environmental data used in scientific reporting and environmental management will improve the interpretation of data and simplify the estimation of risk associated with decisions based on ecological studies.

These predictions were examined in the dune swales of an Australian desert, with data on herbaceous species collected along transects up to 14 km from artificial water points between four and 33 years old. A cumulative grazing index was constructed utilizing both the spatial occupation patterns of cattle and the length of exposure. Despite restricting sampling to a narrow habitat, silt/clay content and soil pH influence floristic patterns independent of grazing. The analysis of quadrat data in relation to grazing revealed almost no patterns in plant cover, species richness (at two different scales), or abundance across plant life-form groups. Five species had an increasing response, and seven a decreasing response, while the only species restricted to areas of extremely low grazing pressure was sufficiently rare that it could have occurred there by chance. The dominant annual grass, the most common shrub, and a perennial tussock-forming sedge all decrease with high levels of grazing. Most species exhibit an ephemeral life strategy in response to unreliable rainfall, and this boom and bust strategy effectively doubles as an adaptation to grazing. After 20 years of exposure to managed grazing with domestic stock in Australian dune swales, patterns in species richness have not emerged in response to grazing pressure, the ecosystem has not been transformed to another degradation "state," and there is no evidence that grazing relief refuges provide havens for species highly sensitive to grazing.

We investigated amino-acid and mineral N availability along a 10-site chronosequence of jack pine stands, varying in age from 4 to 60 yr following wildfire. We measured free amino-acid N and mineral N in soil extracts; native proteolytic rates; net N mineralization rates; and microbial amino-acid consumption via a super(15)N leucine tracer assay in 6 of the 10 sites (4, 10, 18, 22, 46, and 55-yr-old). Amino-acid N was consistently low in the youngest sites (4-10 yr), increased rapidly in mid-aged sites (15-22 yr), and was highest in stand age 46. In contrast, mineral N exhibited a parabolic shape (R super(2) = 0.499; P < 0.0001), with the youngest site and the four oldest sites containing the highest amounts of mineral N. As a result, amino-acid N as a percentage of amino-acid N + mineral N was greatest in mid-aged stands (e.g., 67% in the 22-yr-old stand). We observed no trend in proteolytic rates across the chronosequence (P = 0.632). Percentage super(15)N tracer recovery was lowest in the extractable organic N pool for the 4, 10, and 18-yr-old sites, though only site age 10 was significantly different from the older sites. Percentage of recovery in the organic N pool was significantly positively related (R super(2) = 0.798; P < 0.05) to standing pools of amino-acid N. Overall, our results suggest that heterotrophic consumption, not production via proteolysis, controls soil free amino-acid availability. Higher microbial demand for free amino acids in younger vs. older sites likely results from greater microbial C and N limitation early in stand development due to the lack of fresh litter inputs. Since amino-acid N exceeds mineral N in a time period of stand development where jack pine growth rates and N demand are highest, we speculate that amino-acid N may be important to the N economy of these forests.

Vehicles traveling on arterial roadways may also contribute to air pollution spatial variability in urban areas. To characterize the nature of near-road air quality in a complex urban environment, an instrumented all-electric vehicle was deployed to perform high spatial- and temporal-resolution mapping of ultrafine particles (UFPs, particle diameter 100 nm) and carbon monoxide (CO). Sampling was conducted in areas surrounding a highway in Durham, NC, with multiple repeats of the driving route accomplished within a morning or evening commute time frame. Six different nearroad transects were driven, which included features such as noise barriers, vegetation, frontage roads, and densely built houses. Under downwind conditions, median UFP and CO levels in near-road areas located 20-150 m from the highway were a factor of 1.8 and 1.2 higher, respectively, than in areas characterized as urban background. Sampling in multiple near-road neighborhoods during downwind conditions revealed significant variability in absolute UFP and CO concentrations as well as in the rate of concentration attenuation with increasing distance from the highway. During low-speed meandering winds, regional UFP and CO concentrations nearly doubled n relative to crosswind conditions; however, near-road UFP levels were still higher than urban background levels by a factor of 1.2, whereas near-road CO concentrations were not significantly different than the urban background.

Heating, ventilating, and air-conditioning (HVAC) system components such as duct-liners, cooling coils, drip pans, interior insulation and areas subjected to high levels of moisture can create an environment which is prone to biological contamination on surfaces. The movement of indoor air being dominated by HVAC system operation can carry biological contaminants which can expose large numbers of building occupants to bioaerosols. The use of germicidal ultraviolet lamps (UVGI) in commercial and residential HVAC systems has increased. UVGI treatment has focused on HVAC component internal surfaces and airflow. A method to determine the antimicrobial efficacy of UVGI irradiation was developed and tested on the surface of agar plates with four species of vegetative bacteria and seven species of fungi. The percent kill and the kinetics of the rate of killing, k value, were calculated for each organism.

This discipline has proven indispensable for addressing the problems associated with skin exposure to chemicals. The 55th anniversary of Lehman's landmark publication on safety factors presents the opportunity to reflect upon the historical beginnings of dermatotoxicology and the role of regulatory policies on the development of this field over the years. The complexity and sheer volume of information that has been collected makes it difficult to comprehensively cover all aspects of this vast discipline. This overview will touch upon the general concepts of ADME, the various forms of contact dermatitis, and transdermal drug delivery systems. The traditional tests performed in animals and humans to identify allergic or irritant potential of chemicals, in addition to alternative methods such as QSAR modeling will be discussed. The subspecialties of infant and occupational dermatotoxicology, as well as dermatotoxicology of aged and ethnic skin, and skin of the vulva and vagina will also be noted.

AN - 734281613; 20043972 AB - Polychlorinated biphenyls (PCBs) are ubiquitous toxic contaminants. Health risk assessment for this class of chemicals is complex: the current toxic equivalency factor (TEF) method covers dioxin-like (DL-) PCBs, dibenzofurans, and dioxins, but excludes non-DL-PCBs. To address this deficiency, we evaluated published data for several PCB congeners to determine common biomarkers of effect. We found that the most sensitive biomarkers for DL-non-ortho-PCB 77 and PCB 126 are liver enzyme (e.g., ethoxyresorufin-O-deethylase, EROD) induction, circulating thyroxine (T4) decrease, and brain dopamine (DA) elevation. For DL-ortho-PCB 118 and non-DL-ortho-PCB 28 and PCB 153, the most sensitive biomarkers are brain DA decrease and circulating T4 decrease. The only consistent biomarker for both DL- and non-DL-PCBs is circulating T4 decrease. The calculated TEF-(TH), based on the effective dose to decrease T4 by 30% (ED(30)) with reference to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), is identical to both TEF-(WHO98) and TEF-(WHO05) for TCDD and DL-PCBs (correlation coefficients are r=1.00, P<0.001; and r=0.99, P<0.001, respectively). We conclude that T4 decrease is a prospective biomarker for generating a new TEF scheme which includes some non-DL-congeners. The new TEF-(TH) parallels the TEF-(WHO) for DL-PCBs and, most importantly, is useful for non-DL-PCBs in risk assessment to address thyroid endocrine disruption and potentially the neurotoxic effects of PCBs.

AN - 734277818; 19708067 AB - In response to the 2005 revised U.S Environmental Protection Agency's (EPA) Cancer Guidelines, a strategy is being developed to include all mutagenicity and other genotoxicity data with additional information to determine whether the initiating step in carcinogenesis is through a mutagenic mode of action (MOA). This information is necessary to decide if age-dependent adjustment factors (ADAFs) should be applied to the risk assessment. Chromium (VI) [Cr (VI)], a carcinogen in animals and humans via inhalation, was reassessed by the National Toxicology Program (NTP) in 2-year drinking water studies in rodents. From these data, NTP concluded that the results with Cr (VI) showed clear evidence of carcinogenicity in male and female mice and rats. Cr (VI) is also mutagenic, in numerous in vitro assays, in animals (mice and rats) and in humans. Accordingly, Cr (VI) was processed through the MOA framework; postulated key steps in tumor formation were interaction of DNA with Cr (VI) and reduction to Cr (III), mutagenesis, cell proliferation, and tumor formation. Within the timeframe and tumorigenic dose range for early events, genetic changes in mice (single/double-stranded DNA breaks) commence within 24 hr. Mechanistic evidence was also found for oxidative damage and DNA adduct formation contributing to the tumor response. The weight of evidence supports the plausibility that Cr (VI) may act through a mutagenic MOA. Therefore, the Cancer Guidelines recommend a linear extrapolation for the oral risk assessment. Cr (VI) also induces germ cell mutagenicity and causes DNA deletions in developing embryos; thus, it is recommended that the ADAFs be applied. Published 2009 by Wiley-Liss, Inc.

AN - 734271677; 20043233 AB - In this study, genome-wide expression profiling based on Affymetrix ATH1 arrays was used to identify discriminating responses of Arabidopsis thaliana to five herbicides, which contain active ingredients targeting two different branches of amino acid biosynthesis. One herbicide contained glyphosate, which targets 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), while the other four herbicides contain different acetolactate synthase (ALS) inhibiting compounds. In contrast to the herbicide containing glyphosate, which affected only a few transcripts, many effects of the ALS inhibiting herbicides were revealed based on transcriptional changes related to ribosome biogenesis and translation, secondary metabolism, cell wall modification and growth. The expression pattern of a set of 101 genes provided a specific, composite signature that was distinct from other major stress responses and differentiated among herbicides targeting the same enzyme (ALS) or containing the same chemical class of active ingredient (sulfonylurea). A set of homologous genes could be identified in Brassica napus that exhibited a similar expression pattern and correctly distinguished exposure to the five herbicides. Our results show the ability of a limited number of genes to classify and differentiate responses to closely related herbicides in A. thaliana and B. napus and the transferability of a complex transcriptional signature across species.

AN - 733923184; 20194069 AB - Dietary exposure from food to toxic inorganic arsenic (iAs) in the general U.S. population has not been well studied. The goal of this research was to quantify dietary As exposure and analyze the major contributors to total As (tAs) and iAs. Another objective was to compare model predictions with observed data. Probabilistic exposure modeling for dietary As was conducted with the Stochastic Human Exposure and Dose Simulation Dietary (SHEDS-Dietary) model, based on data from the National Health and Nutrition Examination Survey. The dose modeling was conducted by combining the SHEDS-Dietary model with the MENTOR-3P (Modeling ENvironment for TOtal Risk with Physiologically Based Pharmacokinetic Modeling for Populations) system. Model evaluation was conducted via comparing exposure and dose-modeling predictions against duplicate diet data and biomarker measurements, respectively, for the same individuals. The mean modeled tAs exposure from food is 0.38 microg/kg/day, which is approximately 14 times higher than the mean As exposures from the drinking water. The mean iAs exposure from food is 0.05 microg/kg/day (1.96 microg/day), which is approximately two times higher than the mean iAs exposures from the drinking water. The modeled exposure and dose estimates matched well with the duplicate diet data and measured As biomarkers. The major food contributors to iAs exposure were the following: vegetables (24%); fruit juices and fruits (18%); rice (17%); beer and wine (12%); and flour, corn, and wheat (11%). Approximately 10% of tAs exposure from foods is the toxic iAs form. The general U.S. population may be exposed to tAs and iAs more from eating some foods than from drinking water. In addition, this model evaluation effort provides more confidence in the exposure assessment tools used.

AN - 733890176; 19934164 AB - N-Methyl carbamate insecticides are reversible inhibitors of central and peripheral acetylcholinesterase (ChE). Despite their widespread use, there are few studies of neurotoxicity in young animals. To study potential age-related differences, we evaluated seven carbamates (carbaryl, carbofuran, formetanate, methiocarb, methomyl, oxamyl, and propoxur) in preweanling (17 days old or postnatal day [PND] 17) male rats. Motor activity was monitored, and ChE inhibition was measured in brain and red blood cells (RBCs) using a radiometric assay that minimized reactivation of ChE. First, we conducted time-course studies in PND17 Long-Evans male rats, using a single oral dose of each carbamate. Almost all carbamates showed maximal ChE inhibition at a 45-min time point; only methomyl showed an earlier peak effect (15 min). At 24 h, most inhibition had recovered. Next, dose-response data were collected for each carbamate, using four doses and control, with motor activity testing beginning 15 min after dosing and tissue collection at 40-45 min. RBC ChE was generally inhibited to a greater degree than brain. Motor activity was not as sensitive a measure for some of the carbamates, with some differences across carbamates in the shapes of the dose-response curves. Additional studies documented age-related differences by comparing ChE inhibition in PND11, PND17, and adult rats following administration of carbaryl or carbofuran. Only the youngest (PND11) rats were more sensitive than adults to carbaryl, but both younger ages showed more effects than adults with carbofuran. Comparisons of the other carbamates to previous studies in adult rats suggest similar age-related sensitivity. Thus, these data show the time-course and dose-response characteristics for each carbamate and document greater sensitivity of the young for carbofuran and carbaryl.

AN - 733528998; 19864446 AB - Many chemicals released into the environment display estrogenic activity including the oral contraceptive ethinyl estradiol (EE2) and the plastic monomer bisphenol A (BPA). EE2 is present in some aquatic systems at concentrations sufficient to alter reproductive function of fishes. Many concerns have been raised about the potential effects of BPA. The National Toxicology Program rated the potential effects of low doses of BPA on behavior and central nervous system (CNS) as an area of "some concern," whereas most effects were rated as of "negligible" or "minimal" concern. However, the number of robust studies in this area was limited. The current study was designed to determine if maternal exposure to relatively low oral doses of EE2 or BPA in utero and during lactation would alter the expression of well-characterized sexually dimorphic behaviors or alter the age of puberty or reproductive function in the female Long-Evans rat offspring. Pregnant rats were gavaged with vehicle, EE2 (0.05-50 microg/kg/day), or BPA (2, 20, and 200 microg/kg/day) from day 7 of gestation to postnatal day (PND) 18, and the female offspring were studied. EE2 (50 microg/kg/day) increased anogenital distance and reduced pup body weight at PND2, accelerated the age at vaginal opening, reduced F1 fertility and F2 litter sizes, and induced malformations of the external genitalia (5 microg/kg). F1 females exposed to EE2 also displayed a reduced (male-like) saccharin preference (5 microg/kg) and absence of lordosis behavior (15 microg/kg), indications of defeminization of the CNS. BPA had no effect on any of the aforementioned measures. These results demonstrate that developmental exposure to pharmacologically relevant dosage levels of EE2 can permanently disrupt the reproductive morphology and function of the female rat.

The determination of which approaches are most suitable for field applications can be difficult because each assay targets a different gene, in many cases from different microorganisms, leading to variation in assay performance. We describe a performance evaluation of seven end-point PCR and real-time quantitative PCR (qPCR) assays reported to be associated with either ruminant or bovine feces. Each assay was tested against a reference collection of DNA extracts from 247 individual bovine fecal samples representing 11 different populations and 175 fecal DNA extracts from 24 different animal species. Bovine-associated genetic markers were broadly distributed among individual bovine samples ranging from 39 to 93%. Specificity levels of the assays spanned 47.4% to 100%. End-point PCR sensitivity also varied between assays and among different bovine populations. For qPCR assays, the abundance of each host-associated genetic marker was measured within each bovine population and compared to results of a qPCR assay targeting 16S rRNA gene sequences from Bacteroidales. Experiments indicate large discrepancies in the performance of bovine-associated assays across different bovine populations. Variability in assay performance between host populations suggests that the use of bovine microbial source-tracking applications will require a priori characterization at each watershed of interest.

This study was performed as part of a U.S. EPA program to evaluate treatment and disposal alternatives to the current land disposal restriction (LDR) treatment standards for mercury. The stabilized materials were subjected to a suite of leaching tests: one test characterized the solubility and release behavior of mercury as a function of pH between the pH values of 2 and 12; the second test used the toxicity characteristic leaching procedure (TCLP); and the third leaching test used the TCLP "cage" modification. TCLP results showed that leachability of Hg decreased by approximately two orders of magnitude and a maximum of five orders of magnitude. The three leachability test methods produced similar amounts of leached mercury, but the test that studied mercury solubility as a function of pH released slightly higher levels (at pH 2) compared to the TCLP methods. On comparing the results obtained with the standard TCLP and the TCLP cage modification, we learned that the leachates from stabilized wastes containing 50 wt % loading of elemental Hg and HgCl sub(2) were within the LDR requirements. However, wastes containing higher loadings (i.e., 70 wt % loading of Hg and HgCl sub(2)) had leachate concentrations exceeding the 0.2 mg/L treatment standard and therefore would not meet the Resource Conservation and Recovery Act disposal requirements.

Urbanization is a landscape process affecting biodiversity world-wide. Despite many urban-rural studies of bird assemblages, it is still unclear whether more species-rich communities have more individuals, regardless of the level of urbanization. The more-individuals hypothesis assumes that species-rich communities have larger populations, thus reducing the chance of local extinctions.2. Using newly collated avian distribution data for 1 km2 grid cells across Florence, Italy, we show a significantly positive relationship between species richness and assemblage abundance for the whole urban area. This richness-abundance relationship persists for the 1 km2 grid cells with less than 50% of urbanized territory, as well as for the remaining grid cells, with no significant difference in the slope of the relationship. These results support the more-individuals hypothesis as an explanation of patterns in species richness, also in human modified and fragmented habitats.3. However, the intercept of the species richness-abundance relationship is significantly lower for highly urbanized grid cells. Our study confirms that urban communities have lower species richness but counters the common notion that assemblages in densely urbanized ecosystems have more individuals. In Florence, highly inhabited areas show fewer species and lower assemblage abundance.4. Urbanized ecosystems are an ongoing large-scale natural experiment which can be used to test ecological theories empirically.

Killifish (Fundulus heteroclitus) populations in New Bedford Harbor, Massachusetts, USA (NBH) and Newark Bay, New Jersey, USA (NB) are generationally exposed to coplanar PCBs and PAHs and have developed resistance to PCB mediated induction of CYP1A. We hypothesized that fish resistant to CYP1A induction would also exhibit resistance to PCB and PAH induced ROS production and teratogenesis. Killifish embryos from two contaminated (NB, NBH) and two reference-site populations were exposed to vehicle or 3,3'4,4'5-pentachlorobiphenyl (PCB126) or 3-methylcholanthrene (3-MC) and evaluated for in ovo CYP1A activity, heart deformities, and ROS production. Both chemicals significantly increased in ovo ethoxyresorufin-O-deethylase (EROD) and ROS production in reference-site embryos. These chemicals provoked only moderate induction of in ovo EROD in NBH and NB embryos, and neither PCB126 nor 3-MC induced ROS production in these populations. Similarly, heart deformities were significantly induced by PCB126 in reference-site embryos, but had no significant effects on NB and NBH animals. These results indicate that fish resistant to CYP1A induction also exhibit decreased sensitivity to PCB126 and 3-MC-induced ROS production and teratogenesis. These findings further our understanding of toxicant resistance by demonstrating that reduced response to coplanar PCBs and PAHs extends beyond resistance to CYP1A induction to resistance to the physiological and teratogenic effects of these toxicants, responses that undoubtedly contribute to the increased survival of killifish inhabiting contaminated sites.

One data set, from which we derived reference values for fish community indicators, was based on bottom trawl samples collected from 367 randomly located sites during the summers of 1992-1994. A second trawl data set with similar geographic scope from 2000 to 2004 was used to test the robustness of the indicators derived from the reference data set to new data. We constructed a fish community index (FCI) from three basic indicators: number of species per trawl, total abundance per trawl, and an index of trophic balance among three common feeding guilds. The FCI was not correlated with salinity over a range from freshwater to marine and hypersaline conditions (0-52psu). Direct correlations between the index and environmental variables generally were weak, although some were significant (p<0.05). The FCI was negatively correlated with water clarity (secchi depth), water column depth, and sediment toxicity; correlations of the FCI with pH, sediment organic carbon, and sediment silt+clay content were positive. There was a hyperbolic relationship between dissolved oxygen and maximum values of the index, and no significant correlation with watershed land cover at the whole-estuary or estuary-complex scale. Values of all indicators increased between the two time periods. The FCI is a broad indicator of ecological condition for estuaries within the Louisianan Province, with data aggregated at scales ranging from large estuaries to the entire region. Sample density was insufficient to judge performance of the indicators or index at smaller scales.

Elevated concentrations of natural and synthetic androgenic steroids have been shown to adversely affect normal development in indigenous aqueous species. Androgens and their synthetic analogs released from agricultural activities and wastewater discharge may be introduced into drinking water sources. The fate of androgenic steroids during drinking water treatment, specifically the use of chlorine for biological control, has not been extensively studied. As such, this study focuses on the hypochlorite oxidation of a select number of androgenic compounds that vary in their structural composition. Where a favorable reaction is observed, we also attempt to describe the product distribution. The results show compounds that possess a ketonic functional group conjugated with a double bond inhibit oxidation by hypochlorite in the absence of biological or indirect oxidative pathways. Oxidative reactivity in the presence of hypochlorite was favorably correlated with the presence of isolated unsaturated carbon bonds and resulted in various transformation products.

As a result, RNA-based methods have been suggested to study the active microbial fraction in environmental matrices. The aim of this study was to identify bacterial populations in drinking water by analyzing 16S rRNA-based clone libraries. Hollow-fiber ultrafiltration was used to concentrate bacterial communities from 40l of tap water collected at 12 different times during three different summer months from a single point-of-use. Total RNA was extracted from the microbial concentrates and used to develop 16S rRNA-based clone libraries. Phylogenetic analyses of 1231 partial 16S rRNA gene sequences showed that difficult-to-classify bacterial sequences were the most predominant clones, representing 57.6% of the sequences analyzed. Within these unclassified clades, most sequences were closely related to sequences retrieved from previous DNA- and RNA-based drinking water studies. Other bacterial groups represented in this study included Proteobacteria, cyanobacteria, Actinobacteria, Bacteroidetes, and Planctomycetes. Overall, the results suggest that these bacterial groups are amongst potentially active bacteria in drinking water. Diversity analyses of clones generated show that while overall diversity is similar amongst the different months, membership changes with respect to time. The results from this study further improve our understanding of the molecular diversity and bacterial population dynamics of drinking water microbial communities. Moreover, these results provide the sequence foundation for the development of molecular assays that target active drinking water bacteria.

Less is known about the ecology of wood in great rivers than in smaller rivers and streams. We used a probability survey to estimate the abundance of littoral and shoreline wood along the following mid-continent great rivers of the United States in summer 2004-2006: the Missouri River, Upper Mississippi River, and the Ohio River. We counted wood pieces >0.3m in diameter from a zone between the bank full level out into the river 10m. We categorized wood according to its origin and function as 'beached' (transported from upriver but not providing aquatic habitat), 'wet' (origin unknown and providing aquatic habitat; includes snags), or 'anchored' (attached to the bank at its current location and providing aquatic habitat). We counted 5900 pieces of wood at 447 sites across rivers. Approximately 56 percent of pieces were beached, 30 percent were wet, and 14 percent were anchored. Overall, mean abundance of wood was 2.6 pieces of wood 100m-1 of shoreline (approximately 3.0m3 100m-1). Abundance of wood (pieces per unit distance of river) was much lower than has been reported for many smaller streams and rivers. There was more wood along the Upper Mississippi River (3.3 pieces 100m-1) than elsewhere (<=2.4 pieces 100m-1). The mean abundance of wood on the Ohio River decreased significantly between the 2004 and 2005 survey periods due to high flows. Longitudinal patterns in wood abundance were weak. There was less anchored and wet wood along shorelines protected by revetment (e.g., rip rap). There was generally more wood along shorelines where the riparian land use was characterized as forest rather than agriculture or developed. Mean abundance of wood along forested, un-revetted shorelines was approximately four pieces 100m-1 of shoreline (=80 pieces km-1 of river). This estimate of mean wood abundance for what amounts to least disturbed riparian and shoreline conditions is relevant for great river bioassessment and management.

Surfactants, which are commonly used in AF4, were avoided as they may alter suspension characteristics. Aqu/C sub(60 aggregates generated by sonication in deionized water ranged in size from 80 to 260 nm in hydrodynamic diameter (D) sub(h)) as determined by DLS in flow through mode, which was corroborated by analysis of fractions by DLS in batch mode and by TEM. The mass of C sub(60 in each fraction was determined by LC-APPI-MS. Only 5.2 +/- 6.7% of the total aqu/C) sub(6)0 mass had D sub(h less than 80 nm, while 58 +/- 32% of the total aqu/C) sub(6)0 mass had D sub(h between 80 and 150 nm and 14 +/- 9.2% of the total aqu/C) sub(6)0 were between 150 and 260 nm in D sub(h. With the optimal fractionation parameters, 77 +/- 5.8% of the aqu/C) sub(6)0 mass eluted from the AF4 channel, indicating deposition on the AF4 membrane had occurred during fractionation; use of alternative membranes did not reduce deposition. Channel flow splitting increased detector response although channel split ratios greater than 80% of the channel flow led to decreased detector response. This is the first report on the use of AF4 for fractionating a colloidal suspension of aqu/C sub(60.)

AN - 733546229; 20178601 AB - Simian Virus 40 (SV40) immortalization followed by treatment of cells with 3-methylcholanthrene (3-MC) has been used to elicit tumors in athymic mice. 3-MC carcinogenesis has been thoroughly studied, however gene-level interactions between 3-MC and SV40 that could have produced the observed tumors have not been explored. The commercially-available human uroepithelial cell lines were either SV40-immortalized (HUC) or SV40-immortalized and then 3-MC-transformed (HUC-TC). To characterize the SV40 - 3MC interaction, we compared human gene expression in these cell lines using a human cancer array and confirmed selected changes by RT-PCR. Many viral Large T Antigen (Tag) expression-related changes occurred in HUC-TC, and it is concluded that SV40 and 3-MC may act synergistically to transform cells. Changes noted in IFP 9-27, 2'-5' OAS, IF 56, MxA and MxAB were typical of those that occur in response to viral exposure and are part of the innate immune response. Because interferon is crucial to innate immune host defenses and many gene changes were interferon-related, we explored cellular growth responses to exogenous IFN-gamma and found that treatment impeded growth in tumor, but not immortalized HUC on days 4 - 7. Cellular metabolism however, was inhibited in both cell types. We conclude that IFN-gamma metabolic responses were functional in both cell lines, but IFN-gamma anti-proliferative responses functioned only in tumor cells. Synergism of SV40 with 3-MC or other environmental carcinogens may be of concern as SV40 is now endemic in 2-5.9% of the U.S. population. In addition, SV40-immortalization is a generally-accepted method used in many research materials, but the possibility of off-target effects in studies carried out using these cells has not been considered. We hope that our work will stimulate further study of this important phenomenon.

13268932 AB - In response to growing interest in human exposure to perfluorinated compounds (PFCs), the state of Minnesota measured and reported PFC concentrations in fish collected from the Minneapolis-St. Paul area. To better determine the geographical distribution of PFC contamination throughout Minnesota, fish were collected from 59 lakes throughout the state and several areas along the Mississippi River. Composite fish samples were analyzed for 10 PFC analytes by solid-phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC/MS/MS). PFOS (perfluorooctanesulfonate) was the most commonly detected PFC, occurring in 73% of fish from the Mississippi River but only 22% of fish from lakes. Fish from Mississippi River Pool 2 near the Minneapolis-St. Paul area had the highest levels of PFOS, whereas locations upstream had PFOS concentrations below 40 ng/g, the concentration at which Minnesota issues 'one meal per week' fish consumption advice. Fish from most Minnesota lakes tested (88%) had PFOS concentrations below 3 ng/g. Two lakes, McCarrons and Zumbro, contained fish with PFOS levels above 40 ng/g.

Both genetic and environmental factors are implicated in its etiology. The number of individuals identified as having autism has increased dramatically in recent years, but whether some proportion of this increase is real is unknown. If real, susceptible populations may have exposure to controllable exogenous stressors. Using literature AD data from long-term (10-year) studies, we determined cumulative incidence of AD for each cohort within each study. These data for each study were examined for a changepoint year in which the AD cumulative incidence first increased. We used data sets from Denmark, California, Japan, and a worldwide composite of studies. In the Danish, California, and worldwide data sets, we found that an increase in AD cumulative incidence began about 1988-1989. The Japanese study (1988-1996) had AD cumulative incidence increasing continuously, and no changepoint year could be calculated. Although the debate about the nature of increasing autism continues, the potential for this increase to be real and involve exogenous environmental stressors exists. The timing of an increase in autism incidence may help in screening for potential candidate environmental stressors.

AN - 734026004; 20035570 AB - Exposure to inorganic arsenic (iAs) induces cancer in human lungs, urinary bladder, skin, kidney, and liver, with the majority of deaths from lung and bladder cancer. To date, cancer risk assessments for iAs have not relied on mechanistic data, as we have lacked sufficient understanding of arsenic's pharmacokinetics and mode(s) of carcinogenic action (MOA). Furthermore, while there are vast amounts of toxicological data on iAs, relatively little of it has been collected using experimental designs that efficiently support development of biologically based dose-response (BBDR) models and subsequently risk assessment. This review outlines an efficient approach to the development of a BBDR model for iAs that would reduce uncertainties in its cancer risk assessment. This BBDR-based approach is illustrated by using oxidative stress as the carcinogenic MOA for iAs but would be generically applicable to other MOAs. Six major research needs that will facilitate BBDR model development for arsenic-induced cancer are (1) MOA research, which is needed to reduce the uncertainty in risk assessment; (2) development and integration of the pharmacodynamic component (MOA) of the BBDR model; (3) dose-response and extrapolation model selection; (4) the determination of internal human speciated arsenical concentrations to improve physiologically based pharmacokinetic (PBPK) models; (5) animal models of arsenic carcinogenesis; and (6) the determination of the low dose human relationship for death from cancer, particularly in lungs and urinary bladder. The major parts of the BBDR model are arsenic exposure, a physiologically based pharmacokinetic model, reactive species, antioxidant defenses, oxidative stress, cytotoxicity, growth factors, transcription factors, DNA damage, chromosome damage, cell proliferation, mutation accumulation, and cancer. The BBDR model will need to be developed concurrently with data collection so that model uncertainties can be identified and addressed through an iterative process of targeted additional research.

It has been applied to real time NWP, TRMM-SSM/I based multi-analysis, Seasonal Climate Forecasts and Hurricane Forecasts. The novelty of this approach lies in the methodology, which differs from ensemble analysis techniques used elsewhere. Several model outputs are put together with adequate weights to obtain a combined estimation of meteorological parameters. Weights are calculated by least-square minimization of the difference between the model and the observed field during a so-called training period. Although it can be applied successfully on the continuous parameters like temperature, humidity, wind speed and mean sea level pressure, the Multimodel SuperEnsemble gives good results also when applied on the precipitation, a parameter quite difficult to handle with standard post-processing methods. Here we present our methodology for the Multimodel precipitation forecasts, involving a new accurate statistical method for bias correction and a wide spectrum of results over Piemonte very dense non-GTS weather station network.

We report the first N sub(2)O emission measurements from the Gulf of Mexico Hypoxic Zone (GOMHZ), including an estimate of the emission 'pulse' associated with the passage of Tropical Storm Edouard in August, 2008. Prestorm emission rates (25-287 nmol m super(-2) hr super(-1)) and dissolved N sub(2)O concentrations (5 - 30 nmol L super(-1)) were higher than values reported for the Caribbean and western Tropical Atlantic, and on the lower end of the range of observations from deeper coastal hypoxic zones. During the storm, N sub(2)O rich subsurface water was mixed upward, increasing average surface concentrations and emission rates by 23% and 61%, respectively. Approximately 20% of the N sub(2)O within the water column vented to the atmosphere during the storm, equivalent to 13% of the total 'hypoxia season' emission. Relationships between N sub(2)O, NO sub(3) super(-), and apparent oxygen utilization (AOU) suggest enhanced post storm N sub(2)O production, most likely in response to reoxygenation of the water column and redistribution of organic nitrogen. Our results indicate that mixing related emissions contribute significantly to total seasonal emissions and must therefore be included in emission models and inventories for the GOMHZ and other shallow coastal hypoxic zones.

Size distribution of particles emitted into a mesoscale model AN - 1777120288; 13369178 AB - In order to improve the Community Multiscale Air Quality modeling system (CMAQ) performance for ultrafine particle concentrations in the Pacific Northwest, CMAQ v4.4 was modified so that particles are input to the model with an appropriate size distribution. CMAQʼ s default emission size distributions are based on outdated measurements which underrepresent ultrafine particles. At the same time, the size distribution must represent the results of all processes between the point of emission and the smallest resolvable spatial scale of the model. As a computationally efficient and simple solution, size distributions were compiled from published modern observations for traffic-dominated urban areas, power plants, and marine sources at the typical mesoscale air quality model spatial resolution of 4-15 km. CMAQ was modified so that all chemical species are input according to the emission size distribution of traffic-dominated urban areas because this source emits the majority of each aerosol species in the Pacific Northwest. For a summer 2001 case study based around field measurements, CMAQ v4.4 underpredicts the observable aerosol number concentrations by 1-2 orders of magnitude, while CMAQ with new emission size distributions underpredicts by ~1 order of magnitude. The modeled size distributions have improved properties in terms of more distinct Aitken and accumulation modes and a more prominent Aitken mode. Errors remain, especially in the accumulation mode.

Variable fermentor volumes were used to enable enhanced sugar utilization, accounting for differences in glucose and xylose utilization rates. Saccharomyces cerevisiae 424A-LNH-ST was used for fermentation of glucose-xylose mixtures. The dilution rates employed for continuous fermentation were based on earlier batch kinetic studies of ethanol production and sugar utilization. With a feed containing approximately 30 g L super(-1 glucose and 15 g L) super(-)1 xylose, cell washout was observed at a dilution rate of 0.8 h super(-1. At dilution rates below 0.5 h) super(-)1, complete glucose utilization was observed. Xylose consumption in the first-stage 1 L reactor was only 37% at the lowest dilution rate studied, 0.05 h super(-1. At this same flow rate, xylose consumption rose to 69% after subsequently passing through 3 and 1 L reactors in series, primarily due to the longer residence time in the 3 L reactor (0.0167 h) super(-)1 dilution rate).

This model will identify aquatic ecosystems where fish and piscivores and, ultimately, humans (via fish comsumption) are at risk for contamination by mercury. Over a decade, the team, including EPA, NESCAUM, USGS, BioDiversity Research Institute, Ecosystems Research Group and others, has gathered data on mercury, including sources, transport and deposition, and environmental responses. EPA and USGS scientists realized that this data could be integrated into an empirical, regression-based model for assessing risk of mercury contamination in aquatic ecosystems throughout New England. In 2006, EPA Region 1 received a grant to complete MERGANSER through EPA's Advanced Monitoring Initiative. The model, to be completed in 2010, will link a large body of data on mercury levels in fish and piscivores (especially loons) throughout New England to mercury-deposition models and data on mercury sources and ecosystem features. The model will identify variables (e.g., wetlands in contact with lakes, forest type, pH) correlated with mercury levels in biota and use this information to predict contaminant levels in fish and piscivores in unsampled lakes and lake breeding areas. An empirical linkage will be developed between mercury levels in biota and species population effects, such as reproductive impairment. Powerful features of MERGANSER will be its ability to predict changes in mercury levels in fish and piscivores resulting from implementing various policy options, and to identify optimal locations for monitoring. Additionally, the model will be useful for developing mercury models elsewhere where this high level of mercury data is not available.

Sediment-air mercury volatilization fluxes measured at an urban/industrial (Secaucus High School Marsh, New Jersey Meadowlands) and a regional background (Great Bay estuary, Tuckerton, New Jersey) site peaked at midday and were below detection or negative at night. Cumulative mercury fluxes exhibited strong positive correlations with cumulative solar radiation (r (super 2) = 0.97, p < 0.01) consistent with a light-driven mercury volatilization efficiency of about 15 ng Hg mol PAR (super -1) or about 0.06 ng Hg kJ (super -1) . The role of UV and visible light in the volatilization of Hg from air-exposed sediments was examined using a dynamic flux chamber. Sediments were collected from a highly Hg-contaminated site (Berry's Creek estuary), the less mercury-impacted Raritan and Passaic River estuaries, and from mudflats of the freshwater Tivoli South Bay in New York. Mercury volatilization from sediments was 5 to 20 times higher in the presence of visible plus UV-A light than in the dark. Removal of UV light caused Hg volatilization to decrease and UV-A generally drove greater mercury fluxes that UV-B. Across sediment sample, Hg volatilization was inversely related with sediment acid-volatile sulfide concentration (r (super 2) = 0.8, p = 0.02), suggesting that mercury sulfide complexes or solids are not the photochemically active form of mercury in these sediments.

Although ethanol demand is increasing, a growing economic trend in decreased profitability and resource conflicts have called into question the future of grain-based ethanol production Growing emphasis is being placed on utilizing cellulosic feedstocks to produce ethanol, and the need for renewable resources has made the development of cellulosic ethanol a national priority. Cellulosic ethanol production plants are being built in many areas of the United States to evaluate various feedstocks and processes. The waste streams from many varying processes that are being developed contain a variety of components. Differences in ethanol generation processes and feedstocks are producing waste streams unique to biofuel production, which could be potentially harmful to the environment if adequate care is not taken to manage those risks. Waste stream management and utilization of the cellulosic ethanol process are equally important components of the development of this industry.

The influences of two landscape measures, percent row crop cover (%RCC, computed at three spatial scales), and soil permeability (PERM), on baseflow nutrient concentrations were modeled using linear regressions. Quarterly water samples collected for four years were analyzed for nitrate-N (NN), Kjeldahl-N (KN), total-N (TN), and total-P (TP). In till plain streams (n=17), NN concentrations were 8.5-times greater than drift plain streams (n=18), but KN and TP were 20-40% lower at comparable %RCC. These differences resulted in TN/TP molar ratios >80 in till plain streams, but <6 in drift plain streams. For till plain steams regression models based on %RCC accounted for 79% of the variance in NN concentrations but only 27% in drift plain streams. However, regressions on %RCC accounted for 68-75% of the KN and TP concentration variance in the drift plain streams but essentially none in the till plain. Catchment PERM influenced the regional NN/KN ratios which were 10-fold higher in the drift plain streams. For both till and drift streams the catchment scale %RCC gave the best predictions of NN, a water soluble anion, but the smaller spatial scales produced better models for insoluble nutrient species (e.g., KN and TP). Published literature on Ohio streams indicates that these inter-regional differences in nutrient ratios have potential implications for aquatic biota in the receiving streams.

The condition of the ten coastal wetlands with similar hydrology and geomorphology were ranked from least altered to highly altered using a combination of statistical methods and best professional judgment. Variables of plants, soils, and invertebrates were examined separately using principal component analysis to reduce the multidimensional variables to principal component scores. The first principal component scores of each set of variables (i.e., plants, soil, invertebrates) significantly (p<0.05) correlated with both residential land use and watershed nitrogen (N) loads. Using cumulative frequency diagrams, the first principal component scores of each plant, soil, and invertebrate data set were plotted, and natural breaks and best professional judgment were used to rank the first principal component scores among the sites. We weighted all three ranked components equally and calculated an overall salt marsh condition index by summing the three ranks and then transforming the index to a 0-1 scale. The overall salt marsh condition index for the reference coastal wetland set significantly correlated with the residential land use (R=-0.87, p=0.001) and watershed N loads (R=-0.86, p=0.001). Overall, condition deteriorated in salt marshes and their associated discharge streams when subjected to increasing watershed residential land use and N loads.

There is an increasing realization that other environmental factors, including water mixing, solar radiation, water depth, and water clarity, interact with temperature to either exacerbate bleaching or protect coral from mass bleaching. The relative contribution of these factors to variability in mass bleaching at a global scale has not been quantified, but can provide insights when making large-scale predictions of mass bleaching events. Using data from 708 bleaching surveys across the globe, a framework was developed to predict the probability of moderate or severe bleaching as a function of key environmental variables derived from global-scale remote-sensing data. The ability of models to explain spatial and temporal variability in mass bleaching events was quantified. Results indicated approximately 20% improved accuracy of predictions of bleaching when solar radiation and water mixing, in addition to elevated temperature, were incorporated into models, but predictive accuracy was variable among regions. Results provide insights into the effects of environmental parameters on bleaching at a global scale.

Amorphous and crystalline nanoparticles were prepared using sol-gel synthesis techniques. For amorphous TiO2, solute pH in the range of 4-9 had a profound impact on only As (V) sorption. As (III) and As (V) sorption isotherms indicated that sorption capacities of the different TiO2 polymorphs were dependent on the sorption site density, surface area (particle size) and crystalline structure. When normalized to surface area, As (III) surface coverage on the TiO2 surface remained almost constant for particles between 5 and 20nm. However, As (V) surface coverage increased with the degree of crystallinity. X-ray absorption spectroscopic analysis provided evidence of partial As (III) oxidation on amorphous TiO2 rather than crystalline TiO2. The data also indicated that As (III) and As (V) form binuclear bidentate inner-sphere complexes with amorphous TiO2 at neutral pH.

Due to monochloramine autodecomposition, it is difficult to observe the direct reaction of monochloramine with each OP pesticide. Therefore, a model was developed to examine the reaction of monochloramine (NH2Cl) and dichloramine (NHCl2) with chlorpyrifos (CP), diazinon (DZ), and malathion (MA). Monochloramine was found not to be very reactive with each OP pesticides, kNH2Cl,OP=11-21M super(-1)h super(-1). While, dichloramine (NHCl2) was found to be 2 orders of magnitude more reactive with each of the OP pesticides than monochloramine, kNHCl2,OP=2000-2900M super(-1)h super(-1), which is still three orders of magnitude less than the hypochlorous acid reaction rate coefficient with each OP pesticide. For each pesticide, the reactivity of the three chlorinated oxidants was then found to correlate with half-wave potentials (E1/2) of each oxidant. With reaction rate coefficients for the three chlorinated oxidations as well as neutral and alkaline hydrolysis rate coefficients for the pesticides, the model was used to determine the dominant reaction pathways as a function of pH. At pH 6.5, OP pesticide transformation was mostly due to the reaction of hypochlorous acid and dichloramine. Above pH 8, alkaline hydrolysis or the direct reaction with monochloramine was the primary degradation pathway responsible for the transformation of OP pesticides. This demonstrates the ability of models to be used as tools to elucidate degradation pathways and parameterize critical reaction parameters when used with select yet comprehensive data sets.

These multi-model ensembles incorporated a diverse set of meteorological models, chemical mechanisms, and emission inventories. Evaluation of individual model and ensemble forecasts of surface ozone and particulate matter (PM) was performed using data from 119 EPA AIRNow ozone sites and 38 PM sites during a 50-day period in August and September of 2006. From the original set of models, two new bias-corrected model data sets were built, either by applying a simple running mean average to the past 7 days of data or by a Kalman-Filter approach. From the original and two bias-corrected data sets, three ensembles were created by a simple averaging of the seven models. For further improvements three additional weighted model ensembles were created, where individual model weights were calculated using the singular value decomposition method. All six of the ensembles are compared to the individual models and to each other in terms of root mean square error, correlation, and contingency and probabilistic statistics. In most cases, each of the ensembles show improved skill compared to the best of the individual models. The over all best ensemble technique was found to be the combination of Kalman-Filtering and weighted averaging. PM2.5 aerosol ensembles demonstrated significant improvement gains, mostly because the original model's skill was very low.

In 2004-2005, as part of the Environmental Monitoring and Assessment Program for Great River Ecosystems (EMAP-GRE), we measured legacy organochlorines (OCs) (pesticides and polychlorinated biphenyls, PCBs) and emerging compounds (polybrominated diphenyl ethers, PBDEs) in whole fish to estimate human and wildlife exposure risks from fish consumption. PCBs, PBDEs, chlordane, dieldrin and dichlorodiphenyltrichloroethane (DDT) were detected in most samples across all rivers, and hexachlorobenzene was detected in most Ohio River samples. Concentrations were highest in the Ohio River, followed by the Mississippi and Missouri Rivers, respectively. Dieldrin and PCBs posed the greatest risk to humans. Their concentrations exceeded human screening values for cancer risk in 27-54% and 16-98% of river km, respectively. Chlordane exceeded wildlife risk values for kingfisher in 11-96% of river km. PBDE concentrations were highest in large fish in the Missouri and Ohio Rivers (mean>1000ngg super(-1) lipid), with congener 47 most prevalent. OC and PBDE concentrations were positively related to fish size, lipid content, trophic guild, and proximity to urban areas. Contamination of fishes by OCs is widespread among great rivers, although exposure risks appear to be more localized and limited in scope. As an indicator of ecological condition, fish tissue contamination contributes to the overall assessment of great river ecosystems in the U.S. JF - Science of the Total Environment AU - Blocksom, Karen A AU - Walters, David M AU - Jicha, Terri M AU - Lazorchak, James M AU - Angradi, Theodore R AU - Bolgrien, David W AD - U.S. Environmental Protection Agency, National Exposure Research Laboratory, Ecological Exposure Research Division, 26 W.

AN - 745978574; 12744855 AB - BACKGROUND: Tetrachloroethylene, also known as perchloroethylene or perc, is a highly volatile and lipophilic solvent widely used in dry cleaning, textile processing, and metal-cleaning operations. The limited epidemiological and toxicological data available for exposure to perc during developmental lifestages, as well as the evidence for critical windows of exposure, highlight early life as a period of potential susceptibility. METHODS: A literature search was performed to identify all peer-reviewed epidemiological and toxicologial studies examining outcomes from early lifestage exposure to perc, and reviewed by developmental stage for both exposure and outcome. RESULTS: Exposure scenarios to perc unique to early lifestages include transplacental and breast milk intake, along with inhalation, ingestion, or dermal exposure. Toxicokinetics factors that may influence early lifestage susceptibility to perc, along with existing physiologically based pharmacokinetic (PBPK) models, are described. Adverse outcomes examined include: reproductive outcomes examined prior to conception including reduced fertility, adverse effects on sperm, or altered reproductive hormones; prenatal outcomes examined after exposure prior to conception or prenatally including fetal death, birth defects, and decreased birth weight; postnatal outcomes examined after exposure prior to conception, prenatally, or during childhood including neurotoxicity, immunotoxicity, cancer, hepatotoxicity, congential anomalies and mortality; and adult schizophrenia examined after exposure prior to conception. CONCLUSIONS: The limited evidence on early lifestage exposure to perc does not provide sufficient evidence of this sensitive period as being more or less important than exposure at a later lifestage, such as during adulthood. However, there are a number of adverse health effects observed uniquely in early lifestages, and increased sensitivity to visual system deficits is suggested in children. Other outcomes observed in adults may not have been adequately assessed in children to directly compare sensitivity. Birth Defects Res (Part B) 89:50-65, 2010. Published 2009 Wiley-Liss, Inc.

The study was conducted from January to February, 2004 when Harmattan dust appeared to be most pronounced. PM2.5 concentrations at the Nongo American housing compound ranged from 38I14gma3 to 177I14gma3, and PM10 ranged from 80I14gma3 to 358I14gma3, exceeding standards set by EPA and European Commission Environment Directorate-General. PTFE filter samples were analyzed for insoluble and soluble inorganic constituents by XRF and IC, respectively. Sulfur and associated SO 4 2 - concentrations were notably consistent among PM2.5 and PM10 samples which marked a relatively stable S background signal from anthropogenic sources. Enrichment factor (EF) analysis and aerosol mass reconstruction (AMR) techniques were used to isolate potential PM source contributors. The EF's for SiO2, TiO2, Al2O3, Fe2O3, and MnO were near unity which suggests a crustal origin for these elements. EF's for Na2O and K2O were above unity and highly variable, these elements were elevated due to widespread mangrove wood combustion as a fuel source in Conakry. The EF's for Cr were notably high with a median of 7 and interquartile range from 5 to 16, the elevated levels were attributed to unregulated point source and mobile source emitters in and around Conakry.

Part IV: Occupational reentry and public non-dietary exposure and risk AN - 744688399; 13015171 AB - The California Department of Pesticide Regulation (CDPR) and the United States Environmental Protection Agency (USEPA) released revised draft risk assessments for the pesticidal active ingredient, endosulfan, just 2months apart, in November 2007 and January 2008. The exposure estimates, critical to risk assessment, were calculated by each agency using dissimilar approaches in certain aspects. The scenarios for which exposures and risks were estimated also varied somewhat between the two agencies, although there were substantial overlaps that allowed specific comparisons of exposure and risk estimates. Reasons underlying major differences in estimates of exposure for field workers working in treated crops (reentry exposure) are discussed in this paper. Differences in dislodgeable foliar residue levels calculated by CDPR and USEPA, reflecting endosulfan residues encountered by field workers entering treated orchards and fields, contributed the most to discrepancies in reentry exposure estimates between the two agencies. Additionally, because of differences in legal mandates CDPR estimated exposures for members of the public exposed to endosulfan in ambient air and when swimming, whereas USEPA did not.

Part III: Occupational handler exposure and risk AN - 744679442; 13015173 AB - The United States Environmental Protection Agency (USEPA) and the California Department of Pesticide Regulation (CDPR) have authority to regulate pesticides, respectively, within the United States and within the state of California. Both agencies are obligated to protect human and environmental health within the geographical boundaries where they have authority. Risk assessment of pesticidal active ingredients is conducted by both USEPA and CDPR, yet the agencies have different legal mandates that influence how they conduct assessments. Exposure estimates are key inputs into the risk assessment. Both agencies released draft risk assessments for endosulfan in the same time frame, and while some exposure estimates were similar, many differed considerably. This paper focuses on the differences in exposure estimates for individuals involved in endosulfan applications (handler exposures). Although CDPR and USEPA relied on the same data sets for their exposure estimates for most handler scenarios, CDPR estimates were in some cases more than an order of magnitude higher than estimates from USEPA. Reasons underlying these disparities, and their effects on risk estimates and resulting regulatory decisions, are discussed in this paper. Additionally, because of differences in legal mandates, CDPR estimated exposures for scenarios lacking data, whereas USEPA did not.

Both chemicals are chiral: triadimefon has one chiral center with two enantiomers while its enzymatic reduction to triadimenol produces a second chiral center and two diastereomers with two enantiomers each. All six stereoisomers of the two fungicides were separated from each other using a chiral BGB-172 column on a GC-MS system so as to follow stereospecificity in metabolism by rainbow trout hepatic microsomes. In these microsomes the S-(+) enantiomer of triadimefon was transformed to triadimenol 27% faster than the R-(-) enantiomer, forming the four triadimenol stereoisomers at rates different from each other. The most fungi-toxic stereoisomer (1S,2R) was produced at the slowest rate; it was detectable after 8 h, but below the level of method quantitation. The triadimenol stereoisomer ratio pattern produced by the trout microsomes was very different from that of the commercial triadimenol standard, in which the most rat-toxic pair of enantiomers (known as Diastereomer A) is about 85% of the total stereoisomer composition. The trout microsomes produced only about 4% of Diastereomer A. Complementary metabolomic studies with NMR showed that exposure of the separate triadimefon enantiomers and the racemate to rainbow trout for 48 h resulted in different metabolic profiles in the trout liver extracts, i.e., different endogenous metabolite patterns that indicated differences in effects of the two enantiomers.

Landowners that periodically thin a stand can increase growth rates and mitigate loss of timber and carbon stocks from wildfire. Results indicate that thinning and shortening rotations are cost-effective strategies to mitigate wildfire risk. Carbon prices cause landowners to delay both their thinning treatments and the final rotation age. Thinning and extending timber rotations are thus a viable climate-change mitigation option even when stands are susceptible to risks of fire.

Using a stated-preference survey fielded to a large, nationally representative internet panel, we find that WTP to reduce fatal-disease risks (caused by consuming pesticide residues on foods) are similar for several types of cancer and non-cancer diseases and similar to WTP to reduce motor-vehicle crashes. WTP to reduce risk to one's child is uniformly larger than to reduce risk to another adult or to oneself. Estimated values per statistical life are $6DS10 million for adults and $12DS15 million for children.

It was suspected that the source of N fowleri was the domestic water supply which originates from ground water sources. In this study, ground water from the greater Phoenix Metropolitian area was tested for the presence of N. fowleri using a nested polymerase chain reaction approach. Phylogenetic analyses of 16S RNA sequences of bacterial populations in the ground water were performed to examine the potential link between the presence of N. fowleri and bacterial groups inhabiting water wells. The results showed the presence of N. fowleri in five out of six wells sampled and in 26.6% of all ground water samples tested. Phylogenetic analyses showed that beta - and gamma -proteobacteria were the dominant bacterial populations present in the ground water. Bacterial community analyses revealed a very diverse community structure in ground water samples testing positive for N. fowleri.

I: Toxicology and hazard identification. AN - 733927613; 19733203 AB - Endosulfan is persistent in the environment and toxic to wildlife. Legal mandates necessitate that a risk assessments be performed for endosulfan by the California Department of Pesticide Regulation (CDPR) and the United States Environmental Protection Agency (USEPA). This hazard identification (hazard ID) compared critical no-observed effect levels (NOEL) for acute, subchronic and chronic exposure intervals between the agencies. NOELs were discussed in light of their application to numerous exposure scenarios (occupational, general population and dietary). Only the acute oral NOELs differed between CDPR (0.7 mg/kg/day) and USEPA (1.5 mg/kg/day). Pregnant rabbits were considered by CDPR to be more responsive to low gavage doses of endosulfan than non-pregnant female or male rats in the acute study selected by USEPA. NOELs for other exposure routes and durations were similar between agencies. CDPR and USEPA concurred that a Food Quality Protection Act (FQPA, 1996) Safety Factor is not needed after evaluating all studies including a Developmental Neurotoxicity study. The SF was reduced to 1x. NOELs generated from this hazard ID will be used to calculate the Margins of Exposure for all scenarios and subsequently the risk characterization for endosulfan.

Dietary exposure assessment. AN - 733927469; 19733202 AB - The California Department of Pesticide Regulation (CDPR) and the United States Environmental Protection Agency (USEPA) performed dietary exposure assessments for endosulfan in 1998 and 2002, respectively. Results of the USEPA assessment showed an increased risk for the population sub-group "Children 1-6 years" (>100% of the Population Adjusted Dose [PAD]). USEPA then required registrants to satisfy database uncertainties by performing subchronic neurotoxicity and developmental neurotoxicity studies and, based on the results, USEPA decreased the Food Quality Protection Act (FQPA, 1996) Safety Factor from 10x to 1x. Additionally, several tolerances on commodities consumed in quantity by children were cancelled in 2006. CDPR re-evaluated the dietary risk initially performed in 1998 after review of these same studies. Based on a review of the revised USEPA tolerances, decreased usage, decreased consumption, cancellations, and prior health protective margins of exposure (MOEs>100), CDPR determined that it was not necessary to redo the 1998 exposure assessment. In 2007, USEPA conducted a new human health risk assessment for endosulfan combining food+drinking water residues that characterized dietary risk as %PAD=([Exposure/PAD]x100). For all relevant USEPA population sub-groups, the %PADs were<100% (health protective benchmark). Published by Elsevier Inc.

12930165 AB - Pesticide metabolites are routinely measured in the urine of children in the United States. Although the sources of these metabolites are believed to include residues in food from agricultural applications and residues from applications in everyday environments (e.g., homes), few studies have been able to demonstrate an association between indoor residential pesticide applications and pesticide metabolite concentrations. To better quantify the effects of potential risk factors related to demographics, household characteristics, occupation, and pesticide use practices on urinary biomarker levels, we performed a study in a city (Jacksonville, Florida) previously determined to have elevated rates of pesticide use. We enrolled a convenience sample of 203 children ranging in age from 4 to 6years; their caregivers completed a questionnaire and the children provided a urine sample, which was analyzed for a series of organophosphorus and pyrethroid insecticide metabolites. The questionnaire responses substantiated much higher pesticide use for the study participants as compared to other studies. Urinary metabolite concentrations were approximately an order of magnitude higher than concentrations reported for young children in other studies. Few statistically significant differences (at the p<0.05 level) were observed, however, several trends are worth noting. In general, mean urinary pesticide metabolite concentrations were higher for males, Caucasians, and those children living in homes with an indoor pesticide application occurring within the past four weeks. Comparing the urinary pesticide metabolite concentrations in this study to those reported in the NHANES and GerES studies showed that the children living in Jacksonville had substantially higher pyrethroid pesticide exposures than the general populations of the United States and Germany. Further research is needed in communities where routine pesticide use has been documented to obtain information on the most important routes and pathways of exposure and to develop the most effective strategies for reducing pesticide exposures for children.

The study was conducted in a petro-industrial area and the results showed that PAH profiles in lichens were similar to those of the air and pine needles, but completely different from those of soils. Lichens accumulated higher PAH concentrations when compared to the other environmental compartments and its concentrations were significantly and linearly correlated with concentrations of PAHs in soil; we showed that a translation of the lichen PAHs concentrations into regulatory standards is possible, fulfilling one of the most important requirements of using lichens as biomonitors. With lichens we were then able to characterize the air PAHs profile of urban, petro-industrial and background areas. Abstract Copyright (2010) Elsevier, B.V.

However, the carcinogenic mode of action of arsenicals is unknown. We investigated the effects of inorganic arsenic (iAsIII), monomethylarsonous acid (MMAIII), dimethylarsinous acid (DMAIII) and dimethylthioarsinic acid (DMTA), a sulfur containing dimethyl arsenic metabolite, in human bronchial epithelial (BEAS-2B) cells. Cells were exposed to 3, 15 mu M-iAsIII; 0.3, 1 mu M-MMAIII; 0.2, 1 mu M-DMAIII; 0.2, 0.9 mu M-DMTA as non-cytotoxic and minimally cytotoxic (20%) concentrations based on Neutral Red uptake assays after 24h of culture. Total RNA was isolated and gene expression analysis conducted using AffymetrixA+ Human Genome 133 Plus 2.0 arrays. Differentially expressed genes (DEGs) were determined using a one-way ANOVA (p greater than or equal to 0.05) by Rosetta ResolverA+, a Benjamini-Hochberg FDR (false discovery rate) multiple testing correction (90% of DEG altered in the low concentration were also changed at the high concentration. There was a clear dose-response seen in the number of DEGs for all four compounds. iAsIII showed the highest number of DEG at both concentrations (2708 and 123, high and low, respectively). 1749, 420 and 120 DEGs were unique to the high concentrations of iAsIII, MMAIII and DMAIII, respectively. Transferrin receptor is a common DEG in low concentration arsenical treated cells. Ingenuity Pathway Analysis+ revealed p53 signaling (E2F1 and 2, SERPIN), and cell cycle related genes (cyclin D1) were altered by the high concentrations of DMTA, MMAIII and iAsIII. Oxidative stress (DUSP1, GPX2, NQO1, GCLC) and NF- Kappa B signaling (TLR4, NF- Kappa B) pathways were changed by the high concentrations of MMAIII and iAsIII. The genes identified in this study can be a valuable tool to determine the mechanism of arsenic toxicity and cancer formation. A number of similarities were observed in the gene expression profiles of DMAIII and DMTA and also iAsIII and MMAIII.

Some transformation products detected through the use of high performance liquid chromatography-electrospray mass spectrometry are consistent with the formation of N-chloro atrazine. The effects of applied chlorine, pH, and reaction time on the transformation reaction were studied to help understand the practical implications of the transformation on the accurate determination of atrazine in drinking waters. The errors in the determination of atrazine are a function of the type of dechlorinating agent applied during sample preparation and the analytical instrumentation utilized. When a reductive dechlorinating agent, such as sodium sulfite or ascorbic acid is used, the quantification of the atrazine can be inaccurate, ranging from 2-fold at pH 7.5 to 30-fold at pH 6.0. The results suggest HPLC/UV and ammonium chloride quenching may be best for accurate quantification. Hence, the results also appear to have implications for both compliance monitoring and health effects studies that utilize gas chromatography analysis with sodium sulfite or ascorbic acid as the quenching agent.

We used stable carbon (d super(13)C) and oxygen (d super(18)O) isotope ratios in otoliths to differentiate juvenile winter flounder (Pseudopleuronectes americanus) collected from locations along the coast of Rhode Island, USA. Sagittal otoliths from the flounder were analysed for d super(13)C and d super(18)O using isotope ratio mass spectrometry. Plots of d super(13)C v. d super(18)O and discriminant function analysis (DFA) indicated differences among samples from Narragansett Bay, the coastal ponds and the Narrow River. Separations were observed among fish from the upper, middle and lower portions of Narragansett Bay and along the salinity gradient in Narrow River. Otoliths from sites grouped on the basis of low, medium and high salinities also showed differences according to DFA. Correlation analysis indicated a significant negative relationship (r = -0.60, P = 0.009) between seawater temperature and d super(18)O, and a significant positive relationship (r = 0.93, P < 0.001) between salinity and d super(18)O for the combined dataset. These results indicate that d super(13)C and d super(18)O values of juvenile winter flounder otoliths may prove useful for differentiating individuals from various juvenile habitats.

This model was applied to quantify in-canopy air-surface exchange rates and above-canopy NH3 fluxes in a fertilized corn (Zea mays) field. Modeled air-canopy NH3 fluxes agreed well with independent above-canopy flux estimates. Based on the model results, the urea fertilized soil surface was a consistent source of NH3 one month following the fertilizer application, whereas the vegetation canopy was typically a net NH3 sink with the lower portion of the canopy being a constant sink. The model results suggested that the canopy was a sink for some 70% of the estimated soil NH3 emissions. A logical conclusion is that parametrization of within-canopy processes in air quality models are necessary to explore the impact of agricultural field level management practices on regional air quality. Moreover, there are agronomic and environmental benefits to timing liquid fertilizer applications as close to canopy closure as possible. Finally, given the large within-canopy mean NH3 concentration gradients in such agricultural settings, a discussion about the suitability of the proposed model is also presented.

Capping agents are chemicals used in the synthesis of nanoparticles to prevent aggregation. The AgNPs examined in the study were as follows: (a) uncoated AgNPs (H2-AgNPs), (b) electrostatically stabilized (citrate and NaBH4-AgNPs), (c) sterically stabilized (polyvinylpyrrolidone (PVP)-AgNPs), and (d) electrosterically stabilized (branched polyethyleneimine (BPEI)-AgNPs)). The uncoated (H2-AgNPs), the citrate, and NaBH4-coated AgNPs aggregated at higher ionic strengths (100 mM NaNO3) and/or acidic pH (3.0). For these three nanomaterials, chloride (Cl-, 10 mM), as a background electrolyte, resulted in a minimal change in the hydrodynamic diameter even at low pH (3.0). This was limited by the presence of residual silver ions, which resulted in the formation of stable negatively charged AgCl colloids. Furthermore, the presence of Ca2+ (10 mM) resulted in aggregation of the three previously identified AgNPs regardless of the pH. As for PVP coated AgNPs, the ionic strength, pH and electrolyte type had no impact on the aggregation of the sterically stabilized AgNPs. The surface charge and aggregation of the BPEI coated AgNPs varied according to the solution pH.

16192196 AB - In this study, a comparison of model performance of four state-of-the practice Lagrangian dispersion models: CALPUFF, SCIPUFF, HYSPLIT, and FLEXPART is presented. These models were used to simulate the dispersion of the tracer cloud for the European Tracer Experiment (ETEX) and the Cross-Appalachian Tracer Experiment (CAPTEX). Dispersion simulations for each of the modeling systems were done using a common meteorological dataset derived from the NCAR/PSU MM5 model. Statistical evaluation procedures used for model verification follow a hybrid approach based upon the procedures used in the second Atmospheric Transport Model Evaluation Study (ATMES-II) and the NOAA Data Archive of Tracer Experiments and Meteorology (DATEM) project. Verification scores show that the NOAA HYSPLIT model performed best overall, followed by the SCIPUFF and FLEXPART models. CALPUFF performance was significantly poorer than the other three models in the ETEX experiment and improved in CAPTEX, but will require additional analysis to diagnose possible causes of predicted tracer advection errors noted in the ETEX experiment.

This dynamic evaluation approach, an emerging technique being employed as part of a comprehensive model evaluation effort, is specifically designed to assess a model's ability to reproduce observed changes in pollutant concentrations that could be attributed to changes in emissions and variability in meteorological conditions. In this study, changes in the maximum daily average 8-hour (MDA8) ozone concentrations from 3 summer (June, July, August) months spanning 5 consecutive years (2002-2006) from CMAQ (Community Multiscale Air Quality) model results and measurements at CASTNet (Clean Air Status and Trends Network) monitoring sites are investigated. Substantial NOx emissions reductions (close to 40%) occurred during 2003-2004 in the major point source sector, primarily power plants, in the eastern US due to the implementation of the U.S. Environmental Agency's NOx SIP (State Implementation Plan) Call program. Additionally, estimated mobile NOx emissions exhibited a steady decline of about 5% per year. Consequently, this multi-year period serves as a valuable case study for applying dynamic evaluation to test how well the model's O3 response compares to observed changes due to these notable NOx precursor emission reductions as well as to meteorological variability that took place over these periods. The CMAQv4.7 modeling system using the CB-05 (Carbon Bond 2005) chemical mechanism was applied with a 12-km grid cell size and 24 vertical layers on a regional domain covering all states and Canadian provinces east of the Rocky Mountains. Hourly meteorological fields were generated by the MM5 meteorological model and hourly gridded emissions inputs were developed by the SMOKE emissions processing system based on the 2002 NEI (National Emissions Inventory) with updates including county-specific MOBILE6 on-road NOx emissions and hourly CEMS (Continuous Emissions Monitoring Systems) data at major NOx point sources from each summer period. Graphical results of modeled gridded fields of the MDA8 O3 at the 95th percentile reveal broad areas displaying decreases of up to 20% between 2002 and 2006 across the Ohio River Valley region and various eastern states with much smaller changes in the southern and southwestern portions of the domain. Using summer 2002 MDA8 O3 results as a reference, comparisons of relative (%) change reveal the model results closely track the pattern of the overall observed decreases in MDA8 O3 from summer-to-summer. Modeled and observed percentage changes of MDA8 O3 concentrations in groups of individual locations from different sections of the domain are also analyzed to examine how well the model captures spatial variations across the region.

Environmental conditions may act on nanoparticles to change their size, shape, and surface chemistry. Changing these basic characteristics of nanoparticles may result in a final reaction product that is significantly different than the initial nanomaterial. As such, basing long-term risk and toxicity on the initial properties of a nanomaterial may lead to erroneous conclusions if nanoparticles change upon release to the environment.

We measured enantiomeric fractions (EFs) of six PCB atropisomers (PCBs 84, 91, 95, 136, 149, and 174) in surface sediment, fine benthic organic matter (FBOM), coarse particulate organic matter (CPOM), periphyton, Asian clam, mayflies, yellowfin shiner, and semipermeable membrane devices (SPMDs) using gas chromatography (GC-ECD). Nonracemic EFs of PCBs 91, 95, 136, and 149 were measured in almost all samples. Enantiomeric compositions of PCBs 84 and 174 were infrequently detected with racemic EFs measured in samples except for a nonracemic EF of PCB 84 in clams. Nonracemic EFs of PCBs 91, 136, and 149 in SPMDs may be due to desorption of nonracemic residues from FBOM. EFs for some atropisomers were significantly different among FBOM, CPOM, and periphyton, suggesting that their microbial communities have different biotransformation processes. Nonracemic EFs in clams and fish suggest both in vivo biotransformation and uptake of nonracemic residues from their food sources. Longitudinal variability in EFs was generally low among congeners observed in matrices.

Although HSPF is a comprehensive and highly flexible model, a number of investigators noted the model's limited capabilities in representing and simulating best management practices (BMPs), such as detention basins and infiltration trenches. We present herein a stand-alone web-based HSPF BMP Toolkit that allows HSPF to represent and simulate storage and infiltration BMPs in a more comprehensive way.

METHODS: SLE cases (n = 258) were recruited from 11 rheumatology centres across Canada. Controls (without SLE, n = 263) were randomly selected from phone number listings and matched to cases by age, sex and area of residence. Data were collected using a structured telephone interview. RESULTS: An association was seen with outdoor work in the 12 months preceding diagnosis [odds ratio (OR) 2.0; 95% CI 1.1, 3.8]; effect modification by sun reaction was suggested, with the strongest effect among people who reported reacting to midday sun with a blistering sunburn or a rash (OR 7.9; 95% CI 0.97, 64.7). Relatively strong but imprecise associations were seen with work as an artist working with paints, dyes or developing film (OR 3.9; 95% CI 1.3, 12.3) and work that included applying nail polish or nail applications (OR 10.2; 95% CI 1.3, 81.5). Patients were more likely than controls to report participation in pottery or ceramics work as a leisure activity, with an increased risk among individuals with a total frequency of at least 26 days (OR 2.1; 95% CI 1.1, 3.9). Analyses of potential respirable silica exposures suggested an exposure-response gradient (OR 1.0, 1.4. and 2.1 for zero, one and two or more sources of exposure, respectively; trend test P < 0.01). CONCLUSIONS: This study supports the role of specific occupational and non-occupational exposures in the development of SLE.

What is now the Gulf Ecology Division (GED) is located on a 17-acre, federally owned, man-made island in Santa Rosa Sound just south of Gulf Breeze, FL, off the northern shore of Santa Rosa Island and Pensacola Beach (Fig. 1). The first known record of the island was made by William Davison, Port Inspector at the Pensacola Quarantine Station, when, in Sept. 23, 1876, he marked a location for Captain Klem to unload his ballast, about 55 tons of rock. Davison's journal from 1876 was transcribed by an anonymous editor; the transcription is available in the GED library (Davison, 1876). From the 1870s to the 1920s, ships entering the Port of Pensacola were required to discharge ballast before they were fumigated to stop the spread of yellow fever.

Three strains of Pseudomonas aeruginosa PAO1 (wild type and rhlA and pilA mutant) with different motility and attachment properties were used. Varying concentrations of both live and dead cells of P. aeruginosa wild type in sand columns showed no effect on the real conductivity component (sigma '). However, the imaginary conductivity component (sigma ") increased linearly with increasing concentrations of live cells in sand columns, whereas minimal changes were observed with different concentrations of dead cells. A strong power law relationship was observed between sigma " and the number of cells adsorbed onto sand grain surfaces with the rhlA mutant of P. aeruginosa displaying a higher power law exponent compared to the wild type and pilA mutant. In addition, power law exponents were greater in columns with iron oxide-coated sands compared to clean quartz sands. Minimal changes were observed on the sigma ' due to the attachment of P. aeruginosa cells onto sands. We relate the measured low-frequency electrical responses to (1) the distinct electrical properties of live cells and (2) the density of cells attached to mineral surfaces enhancing the surface roughness of sand grains and hence the polarization response. The information obtained from this study enhances our interpretation of microbially induced geoelectrical responses in biostimulated geologic media and may have implications for microbial transport studies.

Corrosion is an important problem in drinking water because it can affect public health due to leaching of lead or other metals into the drinking water. For this reason, a corrosion control program is an important measure to help mitigate exposure to lead in drinking water. The biggest challenge that remains in assessing corrosion control through monitoring programs is the variability of the concentrations of metals such as lead in drinking water, and the interpretation of the results when using different approaches for monitoring. This is due to the many factors that contribute to the leaching of metals from drinking water distribution system materials. Balancing the challenges of stagnation time, sample volume and sampling frequency to assess corrosion control with their practicality and the need to ensure optimal corrosion control treatment are important considerations for regulators and decision-makers to ensure that potential exposure to lead through drinking water is minimized.

These limitations often require risk assessors to estimate bioaccumulation relationships in order to complete the assessments of risk. In the present study, the errors are evaluated with the simple (direct) application of field measured biota-sediment accumulation factors (BSAFs) to other species at a specific location, and to the same species and/or other species at other locations within a site and to other sites. The median (90th percentile) differences in directly applying BSAFs to other species at a specific location were <2.1x (<5.1x) for fish and mussel species groups. The median (90th percentile) differences for applications across locations within a site for a specific species and to other species were <3.3x (<10x) for fish, mussel, and decapod crustacean groups. For direct application across sites, slightly larger median (90th percentile) differences were observed, i.e., <4.0x (<12x). The analysis was performed using a data set of 17,848 BSAFs spanning 392 chemicals/chemical combinations and 71 species.

ER - TY - JOUR T1 - Triclosan Exposure Modulates Estrogen-Dependent Responses in the Female Wistar Rat AN - 856771471; 14152235 AB - Triclosan is an antimicrobial found in personal care and sanitizing products, such as soaps, toothpaste, and hair products. There have been recent concerns for the possible effects on human health, as triclosan has been detected in human breast milk, blood, and urine samples. In a previous study, we found that triclosan alters serum thyroid hormone and testosterone concentrations in male rats. In the current study, we evaluated the effects of triclosan in the female Wistar rat following exposure for 21 days in the Endocrine Disruptor Screening Program pubertal protocol and the weanling uterotrophic assay (3-day exposure). In the pubertal study, triclosan advanced the age of onset of vaginal opening and increased uterine weight at 150 mg/kg, indicative of an estrogenic effect. In the uterotrophic assay, rats received oral doses of triclosan (1.18, 2.35, 4.69, 9.37, 18.75, 37.5, 75, 150, and 300 mg/kg) alone, 3 mu g/kg ethinyl estradiol (EE), or triclosan (same doses as above) plus 3 mu g/kg EE. Uterine weight was increased in the EE group (positive control) as compared with the control but was not affected by triclosan alone. However, there was a significant dose-dependent increase in the group cotreated with EE and triclosan ( greater than or equal to 4.69 mg/kg) as compared with EE alone, indicating a potentiation of the estrogen response on uterine weight. This result was well correlated with potentiated estrogen-induced changes in uterine histology. Serum thyroid hormone concentrations were also suppressed by triclosan in this study, similar to other studies in the male and female rat. In conclusion, triclosan affected estrogen-mediated responses in the pubertal and weanling female rat and also suppressed thyroid hormone in both studies. The lowest effective concentrations in the rodent model are similar to 10 (for estrogen) and 40 (for thyroid hormone) times higher than the highest concentrations reported in human plasma.

The proposed approach utilizes a biclustering method based on iterative optimal reordering (DiMaggio, P. A., McAllister, S. R., Floudas, C. A., Feng, X. J., Rabinowitz, J. D., and Rabitz, H. A. (2008). Biclustering via optimal re-ordering of data matrices in systems biology: rigorous methods and comparative studies. BMC Bioinformatics 9, 458-474.; DiMaggio, P. A., McAllister, S. R., Floudas, C. A., Feng, X. J., Rabinowitz, J. D., and Rabitz, H. A. (2010b). A network flow model for biclustering via optimal re-ordering of data matrices. J. Global. Optim. 47, 343-354.) to identify biclusters corresponding to subsets of chemicals that have similar responses over distinct subsets of the in vitro assays. The biclustering of the in vitro assays is shown to result in significant clustering based on assay target (e.g., cytochrome P450 [CYP] and nuclear receptors) and type (e.g., downregulated BioMAP and biochemical high-throughput screening protein kinase activity assays). An optimal method based on mixed-integer linear optimization for reordering sparse data matrices (DiMaggio, P. A., McAllister, S. R., Floudas, C. A., Feng, X. J., Li, G. Y., Rabinowitz, J. D., and Rabitz, H. A. (2010a). Enhancing molecular discovery using descriptor-free rearrangement clustering techniques for sparse data sets. AIChE J. 56, 405-418.; McAllister, S. R., DiMaggio, P. A., and Floudas, C. A. (2009). Mathematical modeling and efficient optimization methods for the distance-dependent rearrangement clustering problem. J. Global. Optim. 45, 111-129) is then applied to the in vivo data set (21.7% sparse) in order to cluster end points that have similar lowest effect level (LEL) values, where it is observed that the end points are effectively clustered according to (1) animal species (i.e., the chronic mouse and chronic rat end points were clearly separated) and (2) similar physiological attributes (i.e., liver- and reproductive-related end points were found to separately cluster together). As the liver and reproductive end points exhibited the largest degree of correlation, we further analyzed them using regularized logistic regression in a rank-and-drop framework to identify which subset of in vitro features could be utilized for in vivo toxicity prediction. It was observed that the in vivo end points that had similar LEL responses over the 309 chemicals (as determined by the sparse clustering results) also shared a significant subset of selected in vitro descriptors.

However, the capacity of environmental manganese to cause neurotoxicity is of most concern following inhalation exposure. Reference exposure levels (RELs) are values developed by California EPA's Office of Environmental Health Hazard Assessment (OEHHA) to protect the general public from periodic and continual exposures to airborne toxicants. The recently revised guidelines for the development of noncancer RELs encourage the use of benchmark dose methodology where appropriate, and explicitly address the potential susceptibilities associated with early-life exposures (OEHHA, 2008). This paper describes the application of those guidelines to the derivation of RELs to protect the general public from routine 8h and chronic exposures to airborne manganese. The data were amenable to benchmark analysis and the RELs derived reflect the mounting evidence that children represent a population that is differentially susceptible to manganese toxicity.

The mechanism by which Libby amphibole (LA) causes pulmonary injury is not known. The purpose of this study is to compare the cellular stress responses induced in primary human airway epithelial cells (HAECs) exposed to a respirable size fraction ( less than or equal to 2.5 mu m) of Libby amphibole (LA sub(2.5)) to a similar size fraction of a reference amphibole sample amosite (AM sub(2.5)). HAEC were exposed to 0, 2.64, 13.2, or 26.4 mu g/cm super(2) AM sub(2.5) or LA sub(2.5) or to equivalent doses of unfractionated amosite (AM) or LA for 2 or 24 h. Comparable messenger RNA transcript levels were observed for interleukin-8, cyclooxygenase-2, and heme oxygenase-1 in HAEC following a 24-h exposure to AM or LA. Conversely, exposure to AM sub(2.5) resulted in a 4- to 10-fold greater induction in these proinflammatory mediators compared with LA sub(2.5) after 24 h. Evaluation of the expression of 84 additional genes involved in cellular stress and toxicity responses confirmed a more robust response for AM sub(2.5) compared with LA sub(2.5) on an equal mass basis. Differences in total surface area (TSA) by gas adsorption, total particle number, or oxidant generation by the size-fractionated particles did not account for the observed difference in response. In summary, AM sub(2.5) and LA sub(2.5) are at least as potent in stimulating production of proinflammatory cytokines as unfractionated AM and LA. Interestingly, AM sub(2.5) was more potent at inducing a proinflammatory response than LA sub(2.5). This difference could not be explained by differences in mineral contamination between the two samples, TSA, or oxidant generation by the samples.

This research assesses whether the poor and people of color receive the benefits of brownfields revitalization projects or become gentrified. The study reviews the intersection of urban settlement, segregation, racism, brownfields, environmental justice, urban planning and gentrification literature. It first locates U.S. Environmental Protection Agency brownfields pilot sites residing in environmental justice communities. Second, a pre-post demographic study evaluates gentrification variables at the selected locations. Finally, statistical analyses determine whether environmental justice populations experience displacement. Results find that widespread displacement occurs in conjunction with brownfields revitalization projects. Discussion offers environmental justice methodologies able to produce more equitable outcomes and promote sustainability. Adapted from the source document.

In 30 d exposures, no effects were observed on the growth and survival of rainbow trout (Oncorhynchus mykiss), fathead minnow (Pimephales promelas), and channel catfish (Ictalurus punctatus) fed diets contaminated with copper, cadmium, and lead. However, rainbow trout growth was reduced in a dose-dependent manner for diets contaminated with arsenic. These effects of arsenic on fish growth were accompanied by slower feeding rate, reduced food conversion efficiency, liver cell abnormalities, and fecal matter changes suggestive of digestive effects, and occurred to a similar extent whether the diet was exposed to arsenate or arsenite. Effects from these dietary levels of arsenic, and the absence of effects from these dietary levels of metals, were generally consistent with literature reports using laboratory diets amended with toxicant salts. These results also indicated that reported growth effects on rainbow trout fed diets of invertebrates collected from mining-contaminated areas of the Clark Fork River (Montana, USA) or exposed in the laboratory to Clark Fork River sediments are likely more attributable to the arsenic than the metals in those diets.Original Abstract: Nous avons evalue les effets du cuivre, du cadmium, du plomb et de l'arsenic dans le regime alimentaire sur de jeunes poissons en utilisant des proies vivantes, des oligochetes Lumbriculus variegatus. Au cours d'expositions de 30 j, nous n'avons observe aucun effet sur la croissance et la survie de truites arc-en-ciel (Oncorhynchus mykiss), de tetes-de-boule (Pimephales promelas) et de barbues de riviere (Ictalurus punctatus) de regimes alimentaires contamines par le cuivre, le cadmium et le plomb. Cependant, la croissance de la truite arc-en-ciel est reduite en proportion directe de la dose par un regime contamine par l'arsenic. Les effets de l'arsenic comprennent une alimentation ralentie, une efficacite reduite de la conversion de nourriture, des anomalies dans les hepatocytes et des changements dans les feces, ce qui semble representer un impact sur la digestion; ces effets se produisent a la meme intensite que le regime soit expose a l'arseniate ou a l'arsenite. Les effets produits par ces concentrations alimentaires d'arsenic et l'absence d'effets des concentrations alimentaires de metaux s'accordent assez bien avec les resultats de la litterature bases sur des regimes alimentaires modifies au moyen de sels de substances toxiques. Ces resultats indiquent aussi que les effets signales chez les truites arc-en-ciel nourries de regimes d'invertebres recoltes dans des zones contaminees par les operations minieres dans la riviere Clark Fork (Montana, E.-U.) ou exposees en laboratoire a des sediments provenant de la Clark Fork sont plus probablement attribuables a l'arsenic qu'aux metaux dans le regime.

We defined urban and non-urban zones of each river based on mean percent impervious surface extracted from recent land cover data. We estimated that 28-36 % of the rivers, by length, was urbanized. Based on multivariate ordination, the overall structure of the great river assemblages was not different between urban and non-urban zones for either the benthos or snags in any river. Most taxa (82 %) did not exhibit a significant positive or negative effect of urbanization in either river. Many of the taxa that were responsive to zone type were relatively rare (river- and habitat-specific relative abundance < 5 %). For responsive taxa, the effects of urbanization were generally weaker on the Upper Mississippi and Ohio Rivers than on the Lower Missouri River and weaker for snag-surface assemblages than for the littoral benthos. Among the taxa that were more abundant in urban sections were several insect taxa generally considered intolerant of pollution. We speculate that urbanization, possibly due to nutrient enrichment and resulting increased food resources (algae, seston), may improve conditions for these taxa. There appeared to be a threshold in mean percent impervious surface for a great river subcatchment near 5 % above which urban-intolerant taxa were always rare and urban tolerant taxa were often abundant.

The response of cultured thyroid glands to bovine thyroid stimulating hormone (bTSH) and the TH synthesis inhibitors methimazole, 6-propylthiouracil, and perchlorate was determined. Thyroid glands continuously exposed for 12 days to graded concentrations of bTSH released thyroxine (T4) in a dose-dependent manner. Over time, the glands appeared to reach a constant daily rate of T4 release. This suggested that the T4 stores in the glands were initially depleted but continuous release was maintained by synthesis of new hormone. The potency of methimazole, 6-propylthiouracil, and perchlorate for inhibiting T4 release was determined using glands cotreated with a single maximally effective bTSH concentration and graded concentrations of chemical. Inhibition of T4 release was dose dependent for all three chemicals. Perchlorate was the most potent inhibitor of T4 release. Methimazole and 6-propylthiouracil exhibited lower potency than perchlorate but similar potency to each other. The IC50 (mean plus or minus SD) for inhibition of T4 release by the thyroid glands was 1.2 plus or minus 0.55, 8.6 plus or minus 1.3, and 13 plus or minus 4.0 mu M for perchlorate, 6-propylthiouracil, and methimazole, respectively. This model system shows promise as a tool to evaluate the potency of chemicals that inhibit T4 release from thyroid glands and may be predictive of in vivo T4 synthesis inhibition in prometamorphic tadpoles.

Buffalo green monkey cells were inoculated with a 10-fold dilution series of mixed enteroviruses and incubated prior to qRTPCR quantification. Optimal assay conditions included three post infection washes and a 24-hour post infection incubation period based on successful differentiation between infectious and noninfectious viruses and significant and consistent viral replication rates. Ultraviolet disinfection studies were performed to validate the ICC-qRTPCR assay. Using the optimized assay, three-log microbial inactivation was achieved at UV doses of 30--44, 28--42, and 28--29 mJ/cm2 for coxsackievirus B6, echovirus 12, and poliovirus 1, respectively. These results compare favorably to side-by-side assessments using conventional cultural techniques and values previously reported in the literature. This indicates that ICC-qRTPCR is a practical alternative for the simultaneous quantification of enteroviruses in disinfection studies.

Reservoir embayments may have unique characteristics relevant for assessment, and the reservoirs may include zones that combine the characteristics of lotic and lentic systems. The purpose of this study was to characterize spatial variation in benthic macroinvertebrate assemblages of three large upper Missouri River reservoirs in the USA. A probability design was used to select sample sites from Lake Oahe (North and South Dakota), Lake Sakakawea (North Dakota), and Fort Peck Lake (Montana). Sites were chosen to represent the main stem of each reservoir, as well as small, medium, and large bays. The assemblages in all lakes were dominated by oligochaetes (46 - 60 % of total organisms) and chironomids (29 - 49 %). Small and medium bays generally had greater total densities, particularly of chironomids and the burrowing mayfly Hexagenia. Composition and density of the benthos were strongly influenced by depth. Information on the density, distribution, and variability of benthic macroinvertebrates will be used to further refine assessment strategies for large reservoirs.

Many of the metrics are data-intensive and require extensive effort to collect data and compute the metrics. Moreover, individual metrics do not capture all aspects of a system that are relevant to sustainability. A pilot project was initiated to create an approach to measure, monitor, and maintain prosperity and environmental quality of a regional system. The goal was to produce a straightforward, inexpensive methodology that is simple to use and interpret. This requires historical data be readily accessible, metrics must be applicable to the relevant scale, and results must meet the needs of decision-makers. Because sustainability is a multidimensional concept, the research group consisted of a multidisciplinary team that identified the major components of an environmental system. We selected metrics to capture the multidimensionality of sustainability in environmental systems and included: (1) emergy to capture the quality-normalized flow of energy through the system; (2) ecological footprint to capture the impact of humans on the system; (3) green net regional product to estimate human prosperity and well being within the system; and (4) Fisher information to capture the dynamic order of the system. We were able to compute metrics for a test geographic region using existing datasets. Preliminary analysis indicates that each metric reveals a somewhat different trend. These preliminary findings support the idea that characterization of sustainability requires a multidisciplinary approach and demonstrate the need to measure multiple aspects of an environmental system.

Such disorders are hypothesised to be caused by endocrine disrupting contaminants occurring in the lake due to pesticide spills and runoff from bordering agricultural lands. Various studies have resulted in identification of several persistent chlorinated organic pollutants, some of them known endocrine disrupters, in various alligator tissues and fluids. In this report, livers from 12 juvenile alligators inhabiting Lake Apopka and 10 from Lake Woodruff, a control lake, were extracted and analysed using gas chromatography-mass spectrometry with chiral GC columns for identification of both chiral and non-chiral organochlorine pesticides (OCPs, including their metabolites); in so doing, the enantiomer fractions of any chiral OCPs identified were also measured. In Lake Apopka, p,p'-DDE was the most prominent OCP identified, being found in all samples at concentrations ranging from 4 to 779 ng g-1, based on wet weight of the liver samples. Trans- and cis-nonachlor were also detected in all samples at a concentration range of 0.3 to 64 ng g-1; p,p'-DDD was also detected in all samples, but at an even lower concentration of 0.2 to 11 ng g-1. Only 5 chiral OCPs were identified; their enantiomer fractions were mostly non-racemic, indicating pre-ingestion enantioselective biotransformation or enantioselective metabolism by the alligators. p,p'-Dichlorobenzophenone (p,p'-DCBP), a known metabolite of p,p'-dicofol, was detected in all but one sample; most concentrations were <1 ng g-1. Dicofol is known to have been used and spilled near Lake Apopka, and is highly toxic to fish and aquatic invertebrates. Experiments showed that the p,p'-DCBP identified in these samples occurred via thermal degradation during GC analysis of p,p'-dicofol that was present in the liver sample extracts. Only 5 OCPs, at levels much below those in Lake Apopka, were found in control Lake Woodruff.

To explore this question relative to global gene expression, we performed microarray analysis of Salmonella TA100 after treatment under conditions of mutagenesis by the drinking-water mutagen MX and two of its structural homologues, BA-1, and BA-4. Approximately 50% of the genes expressed differentially following MX treatment were unique to MX; the corresponding percentages for BA-1 and BA-4 were 91 and 80, respectively. Among these mutagens, there was no overlap of altered Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways or RegulonDB regulons. Among the 25 Comprehensive Microbial Resource functions altered by these mutagens, only four were altered by more than one mutagen. Thus, the three structural homologues produced distinctly different transcriptional profiles, with none having a single altered KEGG pathway in common. We tested whether structural similarity between a xenobiotic and endogenous metabolites could explain transcriptional changes. For the 830 intracellular metabolites in Salmonella that we examined, BA-1 had a high degree of structural similarity to 2-isopropylmaleate, which is the substrate for isopropylmalate isomerase. The transcription of the gene for this enzyme was suppressed twofold in BA-1-treated cells. Finally, the distinct transcriptional responses of the three structural homologues were not predicted by a set of phenotypic anchors, including mutagenic potency, cytotoxicity, mutation spectra, and physicochemical properties. Ultimately, explanations for varying transcriptional responses induced by compounds with similar structures await an improved understanding of the interactions between small molecules and the cellular machinery.

We investigated the groundwater ecosystem of Minebank Run, a geomorphically degraded urban stream near Baltimore, Maryland in the Chesapeake Bay watershed. Our objectives were to identify the spatial and temporal extent of chemical, microbial, and hydrological factors known to influence denitrification, a microbial process that removes nitrate nitrogen NO sub(3) super(-). Measurements of denitrification enzyme activity confirmed that subsurface sediments at Minebank Run, especially those with high concentrations of organic carbon, have the capacity to denitrify NO sub(3) super(-). Levels of NO sub(3) super(-) in groundwater were lower where more dissolved organic carbon (DOC) was available, suggesting that denitrification and removal of NO sub(3) super(-) in groundwater were limited by DOC availability. Groundwater NO sub(3) super(-) was highest when groundwater levels were highest, which, in turn, corresponded to high oxidation-reduction potential (ORP), indicative of high groundwater-surface water exchange. Stream flow patterns controlled stream bank and bed infiltration and, subsequently, dictated groundwater levels. Declines in water levels likely increased subsurface mixing, which led to low ORP conditions that sustained NO sub(3) super(-) removal via denitrification. The groundwater-surface water interface is a zone of active nitrogen transformation. Management efforts that increase DOC availability to denitrifiers, reduce stream-flow velocity and flashiness, and increase groundwater residence time will likely improve the nitrogen removal capacity of urban stream channels.

The National Risk Management Research Laboratory, part of the U.S. EPA Office of Research and Development, evaluated the effectiveness of stream bank and channel restoration as a means of improving in-stream water quality and biological habitat in Accotink Creek, Fairfax City, Va., using discrete sampling and continuous monitoring techniques before and after restoration. This project monitored the effects of a 549 m (1,800 linear-ft) restoration of degraded stream channel in the North Fork of Accotink Creek. Restoration, which was intended to restore the stream channel to a stable condition, thereby reducing stream bank erosion and sediment loads in the stream, included installation of native plant materials along the stream and bioengineering structures to stabilize the stream channel and bank. Results of sampling and monitoring for 2 years after restoration indicated a slight improvement in biological quality for macroinvertebrate indices such as Virginia Stream Condition Index, Hilsenhoff Biotic Index, and Ephemeroptera, Plecoptera, Trichoptera taxa; the differences were statistically significant at 90% level of confidence with the power of greater than 0.8. However, indices were all below the impairment level, indicating poor water quality conditions. No statistically significant differences in chemical constituents and bacteriological indicator organisms were found before and after restoration as well as upstream and downstream of the restoration. The results indicated that stream restoration alone had little effect in improving the conditions of in-stream water quality and biological habitat, though it has lessened further degradation of stream banks in critical areas where the properties were at risk. Control of storm-water flows by placing best management practices in the watershed might reduce and delay discharge to the stream and may ultimately improve habitat and water quality conditions.

Extracting an essence of decades of inductive empirical research to specify the main characteristics of professions & professionalism, he also turns the research agenda into a direction where deductive clarification is in focus. If the power position & status of a profession is associated with autonomy in the work performance & labour marked monopoly, the basis of these social relations is the sociocultural principle of a good work that reflects theoretical knowledge and self-discipline through the maintenance of occupational & ethical standards. The logic or rationale of professionalism is first and foremost associated with this occupationally determined control of the work performance, which contrasts the ways in which a bureaucracy or marked organizes & controls work. However, Freidson does not really fulfil the ambition to explicate professional expertise as closely associated with both micro and macro levels of society. Another limitation in his approach is a rather narrow & traditional focus on labour marked and occupational policy issues (division of work, specialisation, etc.) at the cost of the more profound discussion of how professionalism is associated with the very notion of modernity. A third problem is about Freidson's somewhat loose distinction between the three ideal types, which leaves it very open how we must proceed methodologically from theoretical to empirical studies of professionalism. My paper sketches an attempt to tackle these shortcomings in Freidson's position on the basis of a sociological approach, which is anchored in Merleau-Ponty's social phenomenology and includes closely related concepts from Bourdieu & others to clarify in what sense the ethical character of spontaneous social interplay is set aside in the modern work life through political and economical power.

On the Role and Relevance of Insecurity and Uncertainty in the Lives of Freelancers in Denmark and Germany T2 - International Sociological Association AN - 743046885; 2010S00798 AB - The paper discusses findings of my PhD research project on work and life patterns of freelancers in Denmark & Germany. In this project I have investigated work & life of freelancers within a cross-national comparative design by means of qualitative interview research. In the paper I am focusing on the role & relevance of insecurity in the narratives of the freelancers. Here a remarkable difference could be found: Whereas insecurity & related fear and anxiety played a huge role in the German interviews ('German Angst') the Danish freelancers attached less importance to the topic of insecurity & showed nearly no sign of related anxiety ('Danish Easy-Going'). Some reasons for this can be found in the different social security backgrounds: The Danish welfare state, characterised by universalism, is much more inclusive for atypical workers (like freelancers) than the German one with its Bismarckian public insurance, where inclusion depends on 'standard employment patterns'. As not all programmes of the Danish welfare state are characterised by universalism (any more) Danish freelancers are faced with exclusion, too. Therefore I am arguing to understand the difference in the context of the concept of "system trust" & its meaning on the micro level.

Paramount to this objective is appropriate sampling strategies. While methodologies have been proposed that focus on optimizing the spatial scale of sampling efforts, sampling depths for ecological risk assessments (ERAs) are usually dictated by the vertical distribution of soil contamination or default to a generic constant. However, these approaches may not adequately reflect site-specific exposures to soil biota. This study uses a meta-analysis approach to quantify the zone of highest biological activity, for soil-dwelling ecological receptors commonly utilized in ERAs. Results suggest sampling strategies should be adaptive allowing for variable depths. If constant depths are utilized, our results suggest that samples should be collected to a depth of approximately 25-30 cm as opposed to shallower depths.

AN - 734203629; 19329556 AB - Exposure to diesel exhaust particles (DEP) has been associated with adverse health outcomes such as inflammation, adjuvancy, and mutagenesis. However, the molecular mechanisms by which DEP inhalation exerts these effects are still largely unknown. We previously reported that exposure to DEP activates the transcription factor Stat3 in airway epithelial cells, a primary target cell of inhaled DEP. To elucidate the functional role of Stat3 activation in these cells, we investigated the function of Stat3 in DEP-induced expression of the p21 gene in the human bronchial epithelial cell line BEAS-2B. We report that DEP exposure induces increased levels of p21 mRNA and protein in a manner that is independent of p53 and Sp1 expression or DNA binding to the p21 gene. Using chromatin immunoprecipitation assays and expression of a dominant-negative Stat3 mutant, we show that activation of Stat3 and its binding to the p21 promoter are required for DEP-induced expression of p21, suggesting that Stat3 plays an essential role in the induction of p21 by DEP. Additional experiments demonstrated that activation of p21 gene expression is dependent on the activation of epidermal growth factor receptor and Src kinase activities. Finally, we provide evidence suggesting that DEP exposure can inhibit the proliferation of human bronchial epithelial cells, suggesting a functional role of p21 activation airway epithelial cells exposed to DEP.

AN - 733904193; 19559085 AB - Development of high-throughput assays for chemical screening and hazard identification is a pressing priority worldwide. One approach uses in vitro, cell-based assays which recapitulate biological events observed in vivo. Neurite outgrowth is one such critical cellular process underlying nervous system development that can be quantified using automated microscopy and image analysis (high content analysis). The present study characterized and compared the PC-12 cell line (NS-1) and primary cultures of cerebellar granular cells (CGC), as models for assessing chemical effects on neurite outgrowth. High content analysis of neurite outgrowth was performed using the Cellomics ArrayScan V(Ti) automated epifluorescent imaging system to acquire and analyze images of beta-tubulin immunostained cells in 96-well plates. Cell viability was assessed using the CellTiter-Glo assay. Culture of NS-1 or CGC in nerve growth factor or serum respectively, rapidly induced neurite outgrowth that increased over four days in vitro. Seven compounds previously shown to affect neurite outgrowth in vitro were tested in both models for changes in total neurite length and cell viability. In NS-1 cells, four chemicals (PKC inhibitor Bis-I, MEK inhibitor U0126, trans-Retinoic acid, methylmercury) inhibited neurite outgrowth, while lead, amphetamine and valproic acid had no effect. In CGC, five chemicals inhibited neurite outgrowth (Bis-I, U0126, lead, methylmercury, and amphetamine), while trans-Retinoic acid decreased cell viability but not neurite outgrowth. Valproic acid was without effect. The sensitivity of the two models was chemical specific: NS-1 cells were more sensitive to Bis-I, methylmercury and trans-Retinoic acid, while CGC were more sensitive to U0126, lead, and amphetamine. For every chemical (except trans-Retinoic acid), neurite outgrowth was equal to or more sensitive than cell viability. In comparison, out of seven chemicals without prior evidence for effects on neurite outgrowth, only one decreased neurite outgrowth (diphenhydramine in CGC). These findings demonstrate that the effects of chemicals on neurite outgrowth may be cell type specific. Published by Elsevier Inc.

AN - 733904082; 19460430 AB - Hazard information essential to guide developmental neurotoxicity risk assessments is limited for many chemicals. As developmental neurotoxicity testing using rodents is laborious and expensive, alternative species such as zebrafish are being adapted for rapid toxicity screening. Assessing the developmental neurotoxicity potential of chemicals in a rapid throughput mode will be aided by the identification and characterization of transcriptional biomarkers that can be measured accurately and rapidly. To this end, the developmental expression profiles of ten nervous system genes were characterized in 1 to 6 days post fertilization zebrafish embryos/larvae using quantitative real time PCR (qRT-PCR). Transcripts of synapsinII a (syn2a) and myelin basic protein (mbp) increased throughout development, while transcripts of gap43, elavl3, nkx2.2a, neurogenin1 (ngn1), alpha1-tubulin, and glial fibrillary acidic protein (gfap) initially increased, but subsequently declined. Transcripts for nestin and sonic hedgehog a (shha) decreased during development. We tested the responses of these potential biomarkers to developmental neurotoxicant exposure, and found that the expression profiles of a subset of genes were altered both during and after exposure to sublethal doses of ethanol, a known developmental neurotoxicant. Collectively, these data indicate that transcript levels of the candidate genes change during development in patterns which are consistent with literature reports, and that the expression of the transcripts is perturbed by treatment with a developmental neurotoxicant (ethanol). These results suggest that the expression profiles of these genes may be useful biomarkers for rapid evaluation of the developmental neurotoxicity potential of chemicals. Published by Elsevier Inc.

AN - 733840856; 19858168 AB - Rodent toxicity studies typically use water bottles to administer test chemicals via drinking water. However, water bottles provide inconsistent exposure of volatile chemicals due to varying headspace, and lead to excessive waste of test material. To refine drinking water toxicity studies in rodents by enhancing sample quality and consistency, and minimizing waste, we designed and implemented a novel water delivery system that keeps the water chilled, headspace free and protected from light. Materials used were resistant to chemical interaction. In this gravity-fed system, a 6-L Teflon water bag, stored in a polystyrene cooler on the cage rack, was connected to a stainless steel manifold delivering water to five cages via specialized drinking valves. Due to the absence of headspace in the water bag, this system allows consistent exposure of volatile chemicals. In addition, small diameter tubing throughout the system reduces the amount of test material residing in the system and minimizes chemical waste.

AN - 733807006; 19950929 AB - This work reports on the first known field study determining emission factors for polychlorinated and polybrominated dibenzodioxins/dibenzofurans (P[C/B]DDs/Fs) and polybrominated diphenyl ethers (PBDEs) from open burning of domestic waste. Two burning waste dump sites in Mexico were sampled using high-volume samplers mounted to a mobile sampling boom. Concurrent measurements of CO and CO(2) allowed determination of emission factors via the carbon balance method. PCDD/F emission factors averaged 823 ng toxic equivalency (TEQ)/kg C(burned) (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 mug/kg C(burned) (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 C(burned) (RSD = 105%), and may originate as reaction products of PBDE combustion or as thermally desorbed impurities from the PBDE flame retardant.

AN - 733796815; 19773591 AB - Existing risk assessment data and procedures can be used to address the estimation of cumulative risk, but there are several uncertainties. These are explored in the context of the State of California's Air Toxic Hot Spots program. Hazard identification for single agents is an established procedure but is much more complex for incompletely characterized or variable mixtures. Hazards from exposure to multiple agents are often only identified by chance. Similar concerns affect dose-response assessment. Although additivity is assumed by default for similar effects at low doses, exceptions are known for specific mixtures and for higher dose rates. Exposure assessment is especially complex for multiple sources, multiple agents from different sources, and target populations or individuals who face cumulative, but not necessarily simultaneous, impacts. With these contributory uncertainties, providing an integrated analysis that can inform risk management and presenting this to a diverse and often already stressed community are challenging.

AN - 733796319; 19789390 AB - Cumulative risks and impacts have taken on different meanings in different regulatory and programmatic contexts at federal and state government levels. Traditional risk assessment methodologies, with considerable limitations, can provide a framework for the evaluation of cumulative risks from chemicals. Under an environmental justice program in California, cumulative impacts are defined to include exposures, public health effects, or environmental effects in a geographic area from the emission or discharge of environmental pollution from all sources, through all media. Furthermore, the evaluation of these effects should take into account sensitive populations and socioeconomic factors where possible and to the extent data are available. Key aspects to this potential approach include the consideration of exposures (versus risk), socioeconomic factors, the geographic or community-level assessment scale, and the inclusion of not only health effects but also environmental effects as contributors to impact. Assessments of this type extend the boundaries of the types of information that toxicologists generally provide for risk management decisions.

AN - 733796177; 19710296 AB - A cumulative risk assessment is generally intended to address concurrent exposure by all exposure routes to a group of chemicals that share a common mechanism of toxicity. However, the contribution of different exposure routes will change over time. This is most critical when estimating risks to infants and children because their exposure sources change rapidly during the first few years of life because of dietary and behavioral changes. In addition, there may be changes in sensitivity to toxicants during this time period, associated with various developmental stages. Traditional risk assessments do not address this progression. Examples of how these factors might be incorporated into an early life risk assessment are provided for lead, dioxins and furans, and organophosphate pesticides. The same concepts may apply to other potentially susceptible subpopulations, such as the elderly.

AN - 733717073; 20055703 AB - The protein tyrosine phosphatases (PTPs) consist of a diverse group of enzymes whose activity opposes that of the tyrosine kinases. As such, the PTPs have critical roles in maintaining signaling quiescence in resting cells and in restoring homeostasis by effecting signal termination. Interest in these enzymes has increased in recent years following the discovery that the activity of PTPs is modulated through redox mechanisms during signaling. The molecular features that enable redox regulation of PTPs during physiological signaling also render them highly susceptible to oxidative and electrophilic inactivation by a broad spectrum of structurally disparate xenobiotic compounds. The loss of PTP activity results in a profound disregulation of protein phosphotyrosine metabolism, leading to widespread and persistent activation of signaling cascades in the cell.

AN - 733582623; 19800024 AB - Arsenic is a human carcinogen, and only recently animal models have been developed that are useful in investigating its carcinogenic mode of action (MOA). However, how arsenic induces cancer is still an open question. In a previous paper, we proposed a model detailing how arsenic might induce DNA lesions leading to cytogenetic damage [A.D. Kligerman, A.H. Tennant, Toxicol. Appl. Pharmacol. 222 (2007) 281-288]. In this model we hypothesized that arsenic does not induce chromosome damage via DNA adduction but induces short-lasting lesions from the action of reactive oxygen species (ROS). These lesions cause single-strand breaks (SSB) that induce chromosome breakage when treatment is in late G(1)- or S-phase. However, if treatment is confined to the G(0)- or early G(1)-phase of the cell cycle, it is predicted that little or no cytogenetic damage will result at the subsequent metaphase. Here, we describe the results from testing this model using monomethylarsonous acid (MMA(III)) and cytosine arabinoside (araC), a DNA chain terminator, to extend the time that DNA lesions remain open during repair to allow the lesions to reach S-phase or interact to form DNA exchanges that would lead to exchange aberrations at metaphase. The results of our study only partially confirmed our hypothesis. Instead, the results indicated that the lesions induced by MMA(III) are quickly repaired through base excision repair, that there is little chance for araC to extend the life of the lesions, and thus the DNA damage induced by arsenicals that leads to chromosome aberrations is very short lived.

AN - 733562350; 20036879 AB - The physiological response to environmental toxicants and drugs is modulated by the thermoregulatory system. Environmental and body temperature can affect the entry of toxicants into the body through pulmonary, cutaneous, and gastrointestinal routes. Thermoregulation can ultimately influence the metabolic clearance of chemicals and their toxicity, including lethality. The thermoregulatory response following acute exposure to many toxic chemicals involves a regulated hypothermic response, characterized by activation of autonomic thermoeffectors to raise heat loss and a behavioral preference for cooler temperatures. Moderate hypothermia in rodents improves recovery and survival following toxic exposure. In relatively large mammals, including humans, the hypothermic response is minimal. Fever-like responses are often seen in humans and other large mammals exposed to many toxicants. Fever is also observed in rodents exposed to some toxicants provided that core temperature can be monitored without disturbing the animal (e.g., telemetry). Overall, the universal effects of temperature on chemical toxicity call for researchers to have a better understanding of how body and ambient temperature affect the physiological response to environmental toxicants.

In this paper, we extend the EPI to include an index of multiple bad outputs. After deriving the index as a Malmquist Quantity Index, we assemble data from 1998 to 2005 on releases of selected toxic chemicals and electricity generation for a sample of coal-fired power plants in the United States to demonstrate how the EPI can provide initial perspectives on trends in releases of toxic chemicals by coal-fired power plants.

Previously, however, risk assessors were unable to describe manganese pharmacokinetics quantitatively across dose levels and routes of exposure, to account for mass balance, and to incorporate this information into a quantitative risk assessment. In addition, the prior risk assessment of inhaled manganese conducted by the U.S. Environmental Protection Agency (EPA) identified a number of specific factors that contributed to uncertainty in the risk assessment. In response to a petition regarding the use of a fuel additive containing manganese, methylcyclopentadienyl manganese tricarbonyl (MMT), the U.S. EPA developed a test rule under the U.S. Clean Air Act that required, among other things, the generation of pharmacokinetic information. This information was intended not only to aid in the design of health outcome studies, but also to help address uncertainties in the risk assessment of manganese. To date, the work conducted in response to the test rule has yielded substantial pharmacokinetic data. This information will enable the generation of physiologically based pharmacokinetic (PBPK) models capable of making quantitative predictions of tissue manganese concentrations following inhalation and oral exposure, across dose levels, and accounting for factors such as duration of exposure, different species of manganese, and changes of age, gender, and reproductive status. The work accomplished in response to the test rule, in combination with other scientific evidence, will enable future manganese risk assessments to consider tissue dosimetry more comprehensively than was previously possible.

The transect was installed parallel to the groundwater flow direction through the treatment area. The ERD technology involves the injection of organic C (OC) to stimulate in situ microbial dechlorination processes. A secondary effect of the ERD treatment at this site, however, is the mobilization of As, as well as Fe and Mn. The concentrations of these elements are low in groundwater collected upgradient of the ERD treatment area, indicating that, in the absence of the injected OC, the As that occurs naturally in the sediment is relatively immobile. Batch experiments conducted using sediments from the site inoculated with an Fe(III)- and As(V)-reducing bacterium and amended with lactate resulted in mobilization of As, Fe and Mn, suggesting that As mobilization in the field is due to microbial processes. In the areas of the transect downgradient of the ERD treatment area, however, the concentrations of OC, As, Fe and Mn in the groundwater are not elevated relative to background levels. The decrease in the dissolved concentration of OC can be attributed to mineralization by microorganisms. The losses of As, Fe and Mn from the dissolved phase must presumably be accompanied by their uptake onto aquifer solids, but chemical extractions provided evidence only for the enrichment of Fe(II). Nor could sorption of As(III) onto sediments be detected by X-ray absorption spectroscopy (XAS) against the background of native As in the sediments, which was present as As(V).

Determining the extent of contamination or the efficacy of decontamination is a challenge, because it may require sampling of the wetted surfaces of distribution infrastructure. This study evaluated two sampling techniques that utilities might use to sample exhumed pipe sections. Polyvinyl chloride (PVC), cement-lined ductile iron, and ductile iron pipe coupons (3 cm x 14 cm) cut from new water main piping were conditioned for three months in dechlorinated Cincinnati, Ohio tap water. Coupons were spiked with Bacillus atrophaeus subsp. globigii, a surrogate for Bacillus anthracis. Brushing and scraping were used to recover the inoculated spores from the coupons. Mean recoveries for all materials ranged from 37 c 30% to 43 c 20% for brushing vs. 24 c 10% to 51 c 29% for scraping. On cement-lined pipe, brushing yielded a significantly different recovery than scraping. No differences were seen between brushing and scraping the PVC and iron pipe coupons. Mean brushing and scraping recoveries from PVC coupons were more variable than mean recoveries from cement-lined and iron coupons. Spore retention differed between pipe materials and the presence of established biofilms also had an impact. Conditioned PVC coupons (with established biofilms) had significantly lower spore retention (31 c 11%) than conditioned cement-lined coupons (61 c 14%) and conditioned iron coupons (71 c 8%).

Manipulative studies have provided insights into different mechanisms by which changes in nutrient concentrations influence aquatic biota, but these studies are limited in spatial scope and in their quantification of nutrient effects on aggregate measures of the invertebrate assemblage. Observational data provide a complementary source of information to manipulative studies, but these data must be analyzed such that the potential effects of spurious correlations are minimized. Propensity scores, a technique developed to analyze human health observational data, are applied here to estimate the effects of increased nutrients on the total taxon richness of stream invertebrates in a large observational data set collected from the western United States. The analysis indicates that increases in nutrient concentration are strongly associated with and cause decreases in invertebrate richness in large, but wadeable, open-canopied streams. These decreases in invertebrate richness were not mediated by periphyton biomass, a commonly proposed mechanism by which nutrients influence invertebrates. In smaller, closed-canopied streams, increases in nutrients were associated with small increases in total richness that were not statistically significant. Using propensity scores can greatly improve the accuracy of insights drawn from observational data by minimizing the potential that factors other than the factor of interest may confound the results.

This model predicts serum and urine concentrations of five DEHP metabolites: MEHP, 5oxo-MEHP, 5OH-MEHP, 5cx-MEPP, and 2cx-MMHP. The model was calibrated using data from an individual who dosed himself with 48.5mg DEHP, and then took blood and urine samples over a 44-h period. The calibrated model was then used in two applications: one on a second set of individuals whose exposure to DEHP was through PVC medical devices in a blood platelet donation procedure, and one on background exposures in the United States (US). Based on 2001/02 NHANES data, median US background urine concentrations of MEHP, 5OH-MEHP, and 5oxo-MEHP are 4.1, 20.1, and 14.0kg/l, respectively. Creatine and urine volume-correction approaches were used to backcalculate an average daily dose of DEHP in the range of 0.6-2.2kg/kgperday. A 'background cohort' including 8 individuals and 57 complete days of urination were assumed to be exposed to1.5kg/kgperday, spread out in equal doses of 0.3kg/kgperday at 0900, 1200, 1500, 1800, and 2100h. The average predicted urine concentrations were 4.6, 15.9, and 9.4kg/l for MEHP, 5OH-MEHP, and 5oxo-MEHP. These are similar, but the two secondary metabolites are slightly lower than medians found in NHANES. This slight difference between the NHANES results and the background simulations could have been due to differences in metabolism between the individual who provided the calibration data (61-year-old Caucasian male) and the general US population. Another explanation evaluated was that urine concentrations further from the time of exposure may have larger disparities between MEHP and the two secondary metabolites as compared with concentrations measured closer to the time of exposure.

It is important to evaluate quantitatively these surrogates against measured pollutant concentrations to determine how their use affects the interpretation of epidemiological study results. In this study, we quantified the implications of using exposure models derived from validation studies, and other alternative surrogate models with varying amounts of measurement error on epidemiological study findings. We compared previously developed multiple regression models characterizing residential indoor nitrogen dioxide (NO sub(2)), fine particulate matter (PM sub(2.5)), and elemental carbon (EC) concentrations to models with less explanatory power that may be applied in the absence of validation studies. We constructed a hypothetical epidemiological study, under a range of odds ratios, and determined the bias and uncertainty caused by the use of various exposure models predicting residential indoor exposure levels. Our simulations illustrated that exposure models with fairly modest R super(2) (0.3 to 0.4 for the previously developed multiple regression models for PM sub(2.5) and NO sub(2)) yielded substantial improvements in epidemiological study performance, relative to the application of regression models created in the absence of validation studies or poorer-performing validation study models (e.g., EC). In many studies, models based on validation data may not be possible, so it may be necessary to use a surrogate model with more measurement error. This analysis provides a technique to quantify the implications of applying various exposure models with different degrees of measurement error in epidemiological research.

Strains of this species typically lack virulence factors (VFs) such as enterotoxins and hemolysins that are produced by other human pathogens of the Aeromonas genus. Microarray profiling of murine small intestinal extracts, 24 h after oral infection with an A. caviae strain, provides evidence of a Th1 type immune response. A large number of gamma-interferon (g-IFN) induced genes are up-regulated as well as several tumor necrosis factor-alpha (TNF-a) transcripts. Aeromonas caviae has always been considered an opportunistic pathogen because it lacks obvious virulence factors. This current effort suggests that an A. caviae strain can colonize the murine intestinal tract and cause what has been described by others as a dysregulatory cytokine response. This response could explain why a number of diarrheal waterborne disease cases have been attributed to A. caviae even though it lacks obvious enteropathogenic properties.Original Abstract: Aeromonas caviae a ete associee a des maladies gastro-intestinales chez l'humain. Les souches appartenant a cette espece sont typiquement depourvues de facteurs de virulence (FV) tels que les enterotoxines et les hemolysines qui sont produites par d'autres pathogenes humains du genre Aeromonas. Une determination des profils sur des puces d'ADN d'extraits d'intestin grele de souris, obtenus 24 h apres une infection orale avec une souche de A. caviae, fournit des preuves de l'existence d'une reponse immune de type Th1. Un grand nombre de genes induits par l'interferon-gamma (IFN-g) sont actives, ainsi que plusieurs transcrits du facteur necrosant des tumeurs alpha (TNF-a). Aeromonas caviae a toujours ete consideree comme pathogene opportuniste car elle etait depourvue de facteurs de virulence. Le present travail suggere qu'une souche de A. caviae peut coloniser le tractus intestinal de la souris et causer ce qui est decrit par d'autres comme une reponse de deregulation par les cytokines. Cette reponse pourrait expliquer pourquoi un certain nombre de maladies vehiculees par l'eau qui causent des diarrhees ont ete attribuees a A. caviae, meme si cette bacterie ne possede pas de proprietes enteropathogenes evidentes.

To improve the predictability of gas production, landfill gas (LFG) composition and flow rates were monitored for 4 yr from one conventional and two bioreactor landfill cells at the Outer Loop Landfill in Louisville, KY, The ultimate methane yield (LO) was estimated from the biochemical methane (CH(4)) potential of freshly buried refuse and the decay rate constant (k) was estimated from measured CH4 collection. The site-specific LO was estimated to be 48.4 m(3)-CH(4) wet Mg-1. The estimated decay rate in the conventionai cell (0.06 yr-1) was comparable to the AP-42 default value of 0.04 yr-1, whereas estimates for the two bioreactor cells were substantially higher (-0.11 yr-1). The data document the ability of the bioreactor operation to enhance landfill CH4 generation, although the estimated decay rate is sensitive to the selected LO. The more rapid decomposition in the bioreactor cells reduces the length of time over which gas will be produced and emphasizes the importance of having a LFG collection system operational once the waste receives added moisture.

This paper analyzes that assumption and provides information on the temporal and spatial distributions associated with school commuting. The data were obtained using Oak Ridge National Laboratory's LandScan USA population distribution model applied to Philadelphia, PA. It is a high-resolution model used to allocate individual school-aged children to both a home and school location, and to devise a minimum-time home-to-school commuting path (called a trace) between the two locations. LandScan relies heavily on Geographic Information System (GIS) data. With respect to school children attending school in their home census tract, the vast majority does not in Philadelphia. Our analyses found that: (1) about 32% of the students walk across two or more census tracts going to school and 40% of them walk across four or more census blocks; and (2) 60% drive across four or more census tracts going to school and 50% drive across 10 or more census blocks. We also find that: (3) using a 5-min commuting time interval - as opposed to the modeled 'trace' - results in misclassifying the 'actual' path taken in 90% of the census blocks, 70% of the block groups, and 50% of the tracts; (4) a 1-min time interval is needed to reasonably resolve time spent in the various census unit designations; and (5) approximately 50% of both the homes and schools of Philadelphia school children are located within 160m of highly traveled roads, and 64% of the schools are located within 200m. These findings are very important when modeling school children's exposures, especially, when ascertaining the impacts of near-roadway concentrations on their total daily body burden. As many school children also travel along these streets and roadways to get to school, a majority of children in Philadelphia are in mobile source-dominated locations most of the day. We hypothesize that exposures of school children in Philadelphia to benzene and particulate matter will be much higher than if home and school locations and commuting paths at a 1-min time resolution are not explicitly modeled in an exposure assessment. Undertaking such an assessment will be the topic of a future paper.

In broad terms, the review has highlighted the relative importance of vertical water column stability and horizontal transport processes in influencing the abundance and composition of phytoplankton. In coastal waters, the seasonal stabilization and de-stabilization of the water column accounts for most of the natural variation in both phytoplankton species composition and biomass. Much of the remaining natural variability can be explained by the interaction of phytoplankton with a number of oceanographic features and processes such as the presence of tidal and thermohaline fronts, wind and topographically associated coastal upwelling, advection landward of offshore water masses and the flow of coastal and oceanic currents. In estuarine waters, the scenario is somewhat reversed, and although seasonality is important in broad terms, the structure of phytoplankton populations is determined more by local factors operating over much smaller time-scales in the order of days and weeks. The interplay of these factors, such as the periodic rise and fall of the tide and episodic changes in river flow, creates a broad range of conditions that result in greater variation in phytoplankton biomass, while at the same time selecting for a reduced number of species that are adapted to survive in this highly changeable environment.

AN - 1777150600; 12509844 AB - Whether or not children are at higher risk from exposure to air pollutants has become a central question in regulatory toxicology. In order to examine this issue for essential metals several questions related to toxicokinetics and toxicodynamics need to be addressed. These include (1) whether exposure patterns among infants and children are likely to result in disproportionately high exposures to substances in ambient air, and (2) whether infants display special susceptibilities in comparison to the general population. In addition, differences in how developing systems handle metals compared to adults, and interactions between specific metals and other substances with common mechanisms, need to be considered. This study examined the toxicodynamic differences between adults and infants exposed to manganese via inhalation and/or dietary routes of exposure.

Solanum tuberosum (Russet Burbank) plants were grown from seed pieces in a mineral soil in pots under greenhouse conditions. Plants were treated with herbicides (cloransulam, dicamba, glyphosate, imazapyr, primsulfuron, sulfometuron, or tribenuron) at simulated drift levels [<0.1 x standard field application rates (f.a.r.)], approximately 14 d after emergence (DAE). Plant height was measured approximately 14 d after treatment (DAT). Production of small tubers and shoot dry weight were determined at approximately 28 DAT. Imazapyr, sulfometuron, and tribenuron caused significant reductions in tuber fresh weight, with the effective concentrations producing a 25% potato tuber fresh weight (EC25) of 0.00038, 0.0016, and 0.0021 x f.a.r. of 1,124, 52, and 9 g active ingredient hectare super(-1) (g a.i. HA super(-1)), respectively. Primisulfuron, dicamba, and cloransulam also significantly reduced tuber fresh weight, but with higher EC25 values of 0.011, 0.07, and 0.010 to 0.2 x f.a.r. of 40, 558, and 18 g a.i. HA super(-1), respectively. Glyphosate had little effect on tuber fresh weight, with a significant reduction in only one experiment. Sulfometuron reduced tuber fresh weight at an EC25 value lower than the EC25 values for shoot dry weight or plant height. For other herbicides, the reduction in tuber fresh weight occurred within the range of EC25 values for other responses. Although additional experiments are required to develop further a phytotoxicity test, these results indicated that tuber production in young potato plants (harvested approximately 42 DAE) may be an effective assay for below-ground asexual reproductive responses to herbicides, especially acetolactate synthase inhibitors.

However, there is little information on the susceptibility of the aged to toxicants. The toxicity of toluene has been well characterized in young adult rodents but there is little information in the aged. Three approaches were used: (1) pharmacokinetic (PK), (2) cardiac biomarkers, and (3) whole-animal physiology to assess whether aging increases susceptibility to toluene in the Brown Norway (BN) rat. Three life stages, young adult, middle aged, and aged (4, 12, and 24 mo, respectively), were administered toluene orally at doses of 0, 0.3, 0.65, or 1 g/kg and subjected to the following: terminated at 45 min or 4 h post dosing, and blood and brain toluene concentration were measured; terminated at 4 h post dosing, and biomarkers of cardiac function were measured; or monitor heart rate (HR), core temperature (Tc), and motor activity (MA) by radiotelemetry before and after dosing. Brain toluene concentration was significantly elevated in aged rats at 4 h after dosing with either 0.3 or 1 g/kg. Blood toluene concentrations were unaffected by age. There were various interactions between aging and toluene-induced effects on cardiac biomarkers. Most notably, toluene exposure led to reductions in mRNA markers for oxidative stress in aged but not younger animals. Toluene also produced a reduction in cardiac endothelin-1 in aged rats. Higher doses of toluene led to tachycardia, hypothermia, and a transient elevation in MA. Aged rats were less sensitive to the tachycardic effects of toluene but showed a prolonged hypothermic response. Elevated brain levels of toluene in aged rats may be attributed to their suppressed cardiovascular and respiratory responses. The expression of several cardiac biochemical markers of toluene exposure in the aged may also reflect differential susceptibility to this toxicant.

In the US, several national estimates have been conducted using a weight-per-construction-area approximation; national estimates using alternative procedures such as those used for other segments of the solid waste stream have not been reported for C&D debris. A materials flow analysis (MFA) approach for estimating C&D debris generation and composition for the US is evaluated. The consumption of construction materials in the US and typical waste factors used for construction materials purchasing were used to estimate the mass of solid waste generated as a result of construction activities. Debris from demolition activities was predicted from various historical construction materials consumption data and estimates of average service lives of the materials. The MFA approach estimated that approximately 610-780 x 10 exp(6) Mg of C&D debris was generated in 2002. The range of C&D debris composition was 42-59% portland cement concrete, 26-43% asphalt concrete, 6-7% wood, 1-3% brick and clay tile, 2-3% asphalt shingles, 1-2% gypsum products, and <1% steel and iron. This predicted mass exceeds previous estimates using other C&D debris predictive methodologies and reflects the large waste stream that exists.

The surface area of the systems ranged from 1.9 to 193.4 km (super 2) . Parameters examined were depth, bottom temperature, bottom salinity, surface chlorophyll a, bottom dissolved oxygen, lead concentration in sediments, silt-clay content of sediments, and number of infaunal benthic species. Statistical methods included means, standard deviations, coefficients of variation, empirical cumulative distribution functions, and contours determined by bivariate interpolation and interpolation by kriging. All of these methods were found to be appropriate depending upon the purpose of the characterization. Contouring was applied only to those systems with at least 23 discrete sample sites (7 systems). Cross-validation and randomization techniques were used to compare the two interpolation methods. Kriging was advantageous over bivariate interpolation when moderate to strong spatial correlation existed in the residuals (that is, after removal of the spatial trend with a nonparametric regression model). When kriging was conducted, the removal of the trend was necessary if the stationarity assumption was to be valid. The Delaware/Maryland coastal bays are shallow, well-mixed (horizontally and vertically) systems that exhibit little or no spatial correlation for the parameters examined. The South and Severn Rivers, subsystems of the Chesapeake Bay, exhibited moderate to strong spatial dependence for some parameters. Randomization techniques were used to evaluate the effect of decreasing the number of sites in kriged parameters. Based upon these randomizations, it was found that 23 discrete sites could be used for kriging in estuaries with characteristics similar to those in the mid-Atlantic and if the samples were collected with a comparable design.

Surface flow is described by the two-dimensional parabolic approximation of the St. Venant equation, using Manning's equation of motion; subsurface flow is described by the three-dimensional Richards' equation for the unsaturated zone and by three-dimensional Darcy's law for the saturated zone, using an integrated finite difference formulation. The hydrological component is a dynamic link library implemented within a comprehensive model which simulates surface energy, radiation budget, snow melt, potential evapotranspiration, plant development and plant water uptake. We tested the model by comparing distributed and integrated three-dimensional simulated and observed perched water depth (PWD), stream flow data, and soil water contents for a small catchment. Additional tests were performed for the snow melting algorithm as well as the different hydrological processes involved. The model successfully described the water balance and its components as evidenced by good agreement between measured and modelled data. Abstract Copyright (2010) Elsevier, B.V.

A specially designed boat was used to resuspend the top 3 cm of sediment by a jets of air-water directed towards the bottom. This disturbance was carried out for 3 months in each of two areas with a surface area of 24 and 20 hectares respectively. In a total of 80 stations in these two areas and in two undisturbed areas of 16 and 20 ha, organic matter, porosity, density and redox potential were monitored in sediment bimonthly and free sulphides were monitored in water close to the bottom. Before, during and after disturbance, the impact of daily sediment resuspension on the water column was monitored monthly, as ammonium nitrogen (N-NH (sub 4) ), soluble reactive phosphorus (SRP), dissolved oxygen (DO) and pH. In the whole lagoon, sediment texture was determined at the start and at the end of the experiment in 120 stations, and seaweed (mainly Chaetomorpha linum and Lophosiphonia subadunca) and seagrass (Ruppia cirrhosa) biomasses were estimated in 42 stations every month. The results showed a stable organic matter content in disturbed areas and an increase in undisturbed areas, as well as an increase in seaweed in areas distant from disturbed areas. No significant effect of sediment resuspension on water column N-NH (sub 4) , SRP, DO or pH was found.

Mercury sequestered in upland and wetland soils represents a source that may contribute to mercury contamination in sensitive ecosystems. An improved understanding of mercury cycling in stream ecosystems requires identification and quantification of mercury speciation and transport dynamics in upland and wetland soils within a watershed. This report presents data for soils collected in 2008 from two small watersheds in New York and South Carolina. In New York, 163 samples were taken from multiple depths or soil horizons at 70 separate locations near Fishing Brook, located in Hamilton County. At McTier Creek, in Aiken County, South Carolina, 81 samples from various soil horizons or soil depths were collected from 24 locations. Sample locations within each watershed were selected to characterize soil geochemistry in distinct land-cover compartments. Soils were analyzed for total mercury, selenium, total and carbonate carbon, and 42 other elements. A subset of the samples was also analyzed for methylmercury. JF - U. S.

This so-called bipolar seesaw pattern explains many millennial-scale features identified in paleo-proxy records from both hemispheres. Here we present modeling evidence that suggests that the Southern Hemispheric response to a weakening of the AMOC includes elements that have previously been overlooked. Under present-day conditions, an AMOC weakening leads to an intensification of the negative phase of the Pacific South America (PSA) pattern with its southernmost pole north of the Ross Sea. An intensified PSA pattern may lead to a regional cooling of Marie Byrd Land, thereby favoring an in-phase temperature relationship between the Northern Hemisphere and the western side of the West Antarctic Ice Sheet on millennial timescales. However, under glacial conditions due to reduced tropical diabatic forcing and reduced tropical extratropical teleconnections, the weakening of the AMOC induces a different austral winter-time atmospheric response pattern that is characterized by a wavenumber 2 structure and different air-temperature anomalies. We furthermore demonstrate that the observed CO (sub 2) changes that accompanied major disruptions of the AMOC may have helped to amplify Antarctic warming events (A-events) due to radiative forcing and the polar amplification mechanism. Our modeling results provide a new framework to explain a considerable fraction of the observed millennial-scale variance in Southern Hemispheric climate records during Marine Isotope Stage 3 (MIS3).

This method relies on the assumption that the groundwater end-member can be accurately defined and remains constant. We simulate solute transport within the aquifer during and after single and multiple river flow events, to show that (1) water adjacent to the river will have a concentration intermediate between that of the river and that of regional groundwater and (2) the concentration of groundwater discharge will approach that of regional groundwater after a flow event but may take many months or years before it reaches it. In applying chemical base flow separation, if the concentration in the river prior to a flow event is used to represent the pre-event or groundwater end-member, then the groundwater contribution to streamflow will be overestimated. Alternatively, if the concentration of regional groundwater a sufficient distance from the river is used, then the pre-event contribution to streamflow will be underestimated. Changes in concentration of groundwater discharge following changes in river stage predicted by a simple model of stream-aquifer flows show remarkable similarity to changes in river chemistry measured over a 9 month period in the Cockburn River, southeast Australia. If the regional groundwater value was used as the groundwater end-member, chemical base flow separation techniques would attribute 8% of streamflow to groundwater, as opposed to 25% if the maximum stream flow value was used.

Analytical solutions provide one alternative for interpreting test results. In this work, an exact analytical solution to two-dimensional equations describing the governing processes acting on a dissolved compound during a modified push-pull test (advection, longitudinal and transverse dispersion, first-order decay, and rate-limited sorption/partitioning in steady, divergent, and convergent flow fields) is developed. The coupling of this solution with inverse modeling to estimate aquifer parameters provides an efficient methodology for subsurface characterization. Synthetic data for single-well push-pull tests are employed to demonstrate the utility of the solution for determining (1) estimates of aquifer longitudinal and transverse dispersivities, (2) sorption distribution coefficients and rate constants, and (3) non-aqueous phase liquid (NAPL) saturations. Employment of the solution to estimate NAPL saturations based on partitioning and non-partitioning tracers is designed to overcome limitations of previous efforts by including rate-limited mass transfer. This solution provides a new tool for use by practitioners when interpreting single-well push-pull test results.

We collected comprehensive, spatially referenced physicochemical data (pH, dissolved oxygen, temperature, and specific conductance) from the partially mined Buckhorn Creek, KY, watershed in summer 2005 (n = 239 sites) and spring 2006 (n = 494 sites). We found conductivity was >10X higher in mined streams than in forested streams. Semivariograms, which quantify the degree of spatial dependence in chemistry values, indicated summer temperatures in both mined and unmined portions of the watershed had similar lag distances (approximately 5 km). Data for other parameters and seasons, however, violated model assumptions because of strong confluence effects in headwaters. We therefore developed a post hoc predictive model for water physicochemistry downstream of confluences using watershed areas as weighting factors. This weighted average model accurately predicted downstream conductivity (mean absolute error, MAE = 55.34 mu S cm (super -1) ), pH (MAE = 0.16 units), and temperature (MAE = 0.41 degrees C) for confluences in Buckhorn Creek and two additional watersheds with headwater disturbance in West Virginia and Ohio. Use of semivariograms or predictive confluence models can help regulatory agents identify downstream influence of headwater streams and presence of a "significant nexus" with downstream waters.
