AN - 80082157; 14709629 AB - Cytochrome P450-dependent oxidation and glutathione (GSH)-dependent conjugation are the primary routes of metabolism of haloalkanes. Using rat liver microsomes and cytosol, we investigated the metabolism of two halopropanes found on the U.S. Environmental Protection Agency Contaminant Candidate List, 1,3-dichloropropane (1,3-DCP) and 2,2-dichloropropane (2,2-DCP). An automated headspace technique using gas chromatography was developed to determine rates of metabolism. Additional dihaloalkanes (1,2-dichloroethane, 1,2-dichloropropane, 1,4-dichlorobutane, 1,2-dibromoethane, 1,2-dibromopropane, 1,4-dibromobutane) were evaluated to assess structure-activity relationships. In general, brominated dihaloalkanes were eliminated from rat cytosol faster than chlorinated dihaloalkanes, reflecting the expected halide order of reactivity (Br > Cl). Furthermore, the rate of GSH conjugation was proportional to alpha,omega-haloalkane chain length. The clearance of 1,3-DCP via the GSH conjugation pathway (1.6 x 10(-4) l/h/mg cytosol protein) was minor relative to the P450 pathway (2.8 x 10(-2) l/h/mg microsomal protein). In contrast, we did not observe metabolism of 2,2-DCP via the GSH-dependent conjugation pathway and observed only a minor level of clearance via the P450 pathway (7 x 10(-4) l/h/mg microsomal protein). Neither compound was mutagenic in various strains of Salmonella, including those containing GSTT1-1, indicating that GSTT1-1 does not metabolize 1,3-DCP or 2,2-DCP to mutagens. Analysis of the reaction products of 1,3-DCP and GSH in cytosol by liquid chromatography/mass spectrometry revealed significant production of S-(3-chloropropyl) glutathione conjugate, indicating that the conjugate half-mustard does not rearrange to form a sulfonium ion, as typically occurs with vicinal dihaloalkanes.

AN - 80074258; 14698938 AB - The proposed National Children's Study has helped raise awareness of the issues related to children's health and the importance of monitoring the growth and development of children from preconception through adulthood. Many genetic predispositions can adversely impact the normal development process, and various environmental exposures have been linked to adverse reproductive health in rodent models and a small number of accidental human exposures. To monitor reproductive health and identify adverse effects at the earliest possible juncture, investigators must develop a network of biomarkers covering all stages and aspects of reproductive development and function. Biomarkers are biological indicators that can be measured repeatedly and are informative on one or more aspects of biological development or function. They can range from the anatomical level down to the molecular level and may provide information on the nature of an exposure, the effect of an exposure, or the susceptibility of individuals or populations to the toxic effects of an exposure. In theory, biomarkers can be used to monitor a wide variety of conditions and responses ranging from abnormal development to early indicators of late-onset disease. The main stumbling block with this theory has been finding appropriate biomarkers for particular conditions and exposures. Such biomarkers must be easily accessible, robust, and sensitive. Ideally, they will be expressed across a large section of the population, and can be monitored quickly, easily, conveniently, and with minimal cost. In this review, we discuss some of the current and emerging biomarkers of human pubertal development.

AN - 80074231; 14698932 AB - Residential proximity to busy roads has been associated with adverse health outcomes, and school location may also be an important determinant of children's exposure to traffic-related pollutants. The goal of this study was to examine the characteristics of public schools (grades K-12) in California (n = 7,460) by proximity to major roads. We determined maximum daily traffic counts for all roads within 150 m of the school using a statewide road network and a geographic information system. Statewide, 173 schools (2.3%) with a total enrollment of 150,323 students were located within 150 m of high-traffic roads (greater than or equal to 50,000 vehicles/day); 536 schools (7.2%) were within 150 m of medium-traffic roads (25,000-49,999 vehicles/day). Traffic exposure was related to race/ethnicity. For example, the overall percentage of nonwhite students was 78% at the schools located near high-traffic roads versus 60% at the schools with very low exposure (no streets with counted traffic data within 150 m). As the traffic exposure of schools increased, the percentage of both non-Hispanic black and Hispanic students attending the schools increased substantially. Traffic exposure was also related to school-based and census-tract-based socioeconomic indicators, including English language learners. The median percentage of children enrolled in free or reduced-price meal programs increased from 40.7% in the group with very low exposure to 60.5% in the highest exposure group. In summary, a substantial number of children in California attend schools close to major roads with very high traffic counts, and a disproportionate number of those students are economically disadvantaged and nonwhite.

AN - 80072246; 14698937 AB - Detection, quantification, and prognosis of environmental exposures in humans has been vastly enhanced by the ability of epidemiologists to collect biospecimens for toxicologic or other laboratory evaluation. Ease of collection and level of invasiveness are commonly cited reasons why study participants fail to provide biospecimens for research purposes. The use of methodologies for the collection of biospecimens in the home offers promise for improving the validity of health effects linked to environmental exposures while maximizing the number and type of specimens capable of being collected in a timely and cost-effective manner. In this review we examine biospecimens (urine and blood) that have been successfully collected from the home environment. Related issues such as storage and transportation will also be examined as well as promising new approaches for collecting less frequently studied biospecimens (including hair follicles, breast milk, semen, and others). Such biospecimens are useful in the monitoring of reproductive development and function.

AN - 67307652; 19712347 AB - 16S rDNA clone libraries were evaluated for detection of fecal source-identifying bacteria from a collapsed equine manure pile. Libraries were constructed using universal eubacterial primers and Bacteroides-Prevotella group-specific primers. Eubacterial sequences indicated that upstream and downstream water samples were predominantly beta- and gamma-Proteobacteria (35 and 19%, respectively), while the manure library consisted predominantly of Firmicutes (31%) and previously unidentified sequences (60%). Manure-specific eubacterial sequences were not detectable beyond 5 m downstream of the pile, suggesting either poor survival or high dilution rates. In contrast, Bacteroides and Prevotella sp. sequences were detected both in manure and downstream using group-specific primers. Novel sequences from Bacteroides and Prevotella analysis produced an equine-specific phylogenetic cluster as compared to previous data sets obtained for human and bovine samples. While these results suggest that some anaerobic fecal bacteria might be potential identifiers for use in source-tracking applications, a comprehensive examination of environmental sequences within these species should be performed before methods targeting these bacterial groups are applied to watersheds for development of microbial source-tracking protocols.

The makeup of aquatic biological assemblages (e.g., fish, macroinvertebrates, algae, riparian birds, etc.) varies dramatically over the landscape, as do the environmental stresses that affect the condition of those assemblages. Ecoregions delineate areas where similar assemblages are likely to occur and, therefore, where similar expectations can be established. For this reason, ecological regions have proven to be an important tool for use in the process of ecological assessment. This article describes four examples of the use of ecological regions in important aspects of environmental monitoring and assessment: (1) design of monitoring networks; (2) estimating expected conditions (criteria development); (3) reporting of results; (4) setting priorities for future monitoring and restoration. By delineating geographic areas with similar characteristics, ecological regions provide a framework for developing relevant indicators, setting expectations through the use of regional reference sites, establishing ecoregion-specific criteria and/or standards, presenting results, focusing models based on relationships between landscape and surface water metrics, and setting regional priorities for management and restoration. The Environmental Protection Agency and many state environmental departments currently use ecoregions to aid the development of environmental criteria, to illustrate current environmental condition, and to guide efforts to maintain and restore physical, chemical and biological integrity in lakes, streams, and rivers.

These ideas center on the Hebraic idea of created nature (real, radically contingent, & artifactual) & of man (an iconoclast, covenant maker, & artificer). It is further shown that both the eschatological (historical- prophetic) & enlightenment (scientific-materialist) components of Hobbes's philosophy originate in these same biblical ideas. Therefore, the often stressed & accustomed division of Leviathan into a secular (Parts I & II) & a religious (Parts III & IV) teaching is mistakenly conceived. Adapted from the source document.

The bulk conductivity was measured using in-situ vertical resistivity probes; the most probable number method was used to characterize the spatial distribution of aerobic heterotrophic and oil-degrading microbial populations. The purpose of this study was to assess if high conductivity observed at aged LNAPL-impacted sites may be related to microbial degradation of LNAPL. The results show higher bulk conductivity coincident with LNAPL-impacted zones, in contrast to geoelectrical models that predict lower conductivity in such zones. The highest bulk conductivity was observed to be associated with zones impacted by residual and free LNAPL. Data from bacteria enumeration from sediments close to the resistivity probes show that oil-degrading microbes make up a larger percentage (5-55%) of the heterotrophic microbial community at depths coincident with the higher conductivity compared to approximately 5% at the uncontaminated location. The coincidence of a higher percentage of oil-degrading microbial populations in zones of higher bulk conductivity suggests that the higher conductivity in these zones may result from increased fluid conductivity related to microbial degradation of LNAPL, consistent with geochemical studies that suggest that intrinsic biodegradation is occurring at the site. The findings from this study point to the fact that biogeochemical processes accompanying biodegradation of contaminants can potentially alter geoelectrical properties of the subsurface impacted media.

When the propagation velocity in the borehole was greater than that in the formation (e.g., an air-filled borehole in the unsaturated zone), only a guided wave propagated along the borehole. As the frequency decreased, both the phase and the group velocities of the guided wave asymptotically approached the phase velocity of a plane wave in the formation. The guided wave radiated electromagnetic energy into the formation, causing its amplitude to decrease. When the propagation velocity in the borehole was less than that in the formation (e.g., a water-filled borehole in the saturated zone), both a refracted wave and a guided wave propagated along the borehole. The velocity of the refracted wave equaled the phase velocity of a plane wave in the formation, and the refracted wave preceded the guided wave. As the frequency decreased, both the phase and the group velocities of the guided wave asymptotically approached the phase velocity of a plane wave in the formation. The guided wave did not radiate electromagnetic energy into the formation. To analyze traces recorded by the prototype tool during laboratory tests, they were compared to traces calculated with the finite-difference method. The first parts of both the recorded and the calculated traces were similar, indicating that guided and refracted waves indeed propagated along the prototype tool.

Natural fractures in the upper Pottsville Formation of Alabama include joints in shale and sandstone, cleats in coal, bed-parallel partings, and fault-related shear fractures. As coalbed methane wells are completed, hydraulic fractures are generated by pumping fluid rapidly into coal, and these fractures can be incorporated into DFN models to assess the impact of hydraulic fracturing on the hydrologic system. Upper Pottsville fracture systems have distinctive statistical attributes that can be used to formulate DFN models on the basis of fracture height, length, spacing, cross-cutting relationships, and kinematic aperture. One set of DFN models features joints, coal beds, and hydraulic fractures. Another set of DFN models incorporates a normal fault and fault-related shear fractures. Compartmentalization analysis indicates that upper Pottsville fracture systems are structurally interconnected, but eliminating poorly transmissive hairline fractures results in the development of numerous hydrologic compartments. The compartmentalization results are insensitive to the presence of hydraulic fractures and thus indicate that hydraulic fractures do not significantly modify the natural hydrologic system. Analysis of a jointed DFN model indicates that a series of first-order reservoir compartments envelops each major coal zone. Analysis of fault-related shear fractures indicates that numerous elongate compartments can conduct fluid along strike of the faults but impede flow along dip of the faults. However, including joints and coal beds in a faulted DFN model results in a large first-order compartment that envelops the complete model and contains an abundance of elongate second-order compartments. Analysis of the faulted DFN model suggests that only a combination of joints, coal beds, and fault-related shear fractures can result in hydraulic communication between reservoir coal beds and shallow coal aquifers. The risk posed by coalbed methane operations to shallow aquifers is interpreted to be minimal or nonexistent. Multiple no-flow boundaries appear to separate reservoir coal zones from shallow coal aquifers, thus the aquifers appear to be shielded from completion and production operations in coalbed methane reservoirs. The faulted DFN model indicates that hydraulic communication between reservoir coal beds and shallow coal aquifers requires highly tortuous flow paths, and production experience from Deerlick Creek Field indicates that faults can be zones of minimal fluid production. Therefore, the risks posed by coalbed methane activities near faults can be regarded as minimal and speculative.

The formations making up the aquifer, the Garber Sandstone and the underlying Wellington Formation, consist of amalgamated fluvial sandstones interbedded with mudstones, siltstones, and some conglomerates (Breit et al., 1990). Water from some of the wells contains naturally occurring arsenic levels that exceed federal standards (EPA, 2001). Past work suggests that the arsenic is concentrated in water produced from sandstones isolated by finer-grained rocks. This is because the low permeability of the finer-grained intervals inhibits the flushing-out of soluble trace substances by freshwater (Schlottmann et al., 1998). Therefore, one strategy for remediation is to selectively produce water from low-arsenic zones and to limit or avoid completion and development of sandstones isolated by finer-grained lithofacies. This strategy requires the development of an improved stratigraphic model that defines the lateral and vertical distribution of arsenic-prone lithofacies. To accomplish this, geophysical logs from oil and water wells, subsurface core, and outcrops are being used to produce stratigraphic cross-sections and maps (such as net-to-gross and sandstone-shale ratio maps). To date, our work suggests that sand-prone and mud-prone packages within these formations can be correlated but that correlation of individual sandstone bodies is problematic. Through integration of on-going companion studies, the projection of outcrop gamma-ray profiles and paleodepositional environment to the subsurface should help to further constrain the habitat of arsenic and better define regional permeability fairways.

Increasing imperviousness has led to higher peak flows and lower base flows. The movement of pollutants and other materials to receiving waters has increased and stream water temperatures have risen. These changes alter the structure and functioning of rivers, streams, and associated riparian corridors and result in changes in ecosystem services. We define a hydrologic disturbance index that indicates varying degrees of disturbance on a reach-by-reach basis, dependent on the aggregate amount of urbanization upstream of each reach. For current conditions this index is more variable than for future conditions, because current land use in the study watershed is more variable, containing mixtures of urban, agricultural, and forested land. In contrast, future land use is projected to be more uniformly urban, leading to a less variable but greater overall degree of hydrologic disturbance. Two effects of urbanization on fish are explored through ecological modeling: effects of streambed disturbance on food availability and effects of stream temperature on spawning. We tabulate food availability as a function of bed-mobility for 30 different fish species. We show that additional stress occurs with additional urbanization of the watershed. We show that the urban-related increase in stream temperatures may cause several warm-water species to actually gain opportunities to spawn in some cases. However, combining food availability and spawning day availability into a single index reveals highly stressful conditions for all fish species under the fully developed scenario.

Two major stratigraphic units in the COA, the Garber Sandstone and Wellington Formation, contain naturally occurring arsenic that exceeds government mandated drinking-water standards (EPA, 2001). Previous work in the COA (Schlottmann et al., 1998) has shown that arsenic concentrations in the aquifer vary with lithofacies. Isolated sandstones (encased by thick shale intervals where flow is reduced) tend to yield water with elevated arsenic levels. In order to better constrain the distribution of arsenic with lithofacies, we have constructed numerous high-resolution spectral gamma-ray profiles of the outcrops using a portable gamma-ray scintillometer. In addition, rock samples associated with each gamma ray reading taken from outcrops were returned to the laboratory for textural analysis. We find that many of the arsenic-bearing lithofacies are characterized by high total gamma-ray counts (associated with K, U and Th). This result is because arsenic in the rocks is associated with iron oxide that appears to be enriched in the finer-grained, clay-rich lithofacies. Calculated permeability profiles mimic fining-upward grain-size profiles characteristic of fluvial depositional settings. Data from previous USGS studies (cores, geochemistry, petrography, and X-ray diffraction) are being incorporated into the evaluation of the gamma-ray responses as well. Results of this work are being integrated with other on-going companion studies to constrain subsurface well log correlation and the reconstruction of paleodepositional environments in the Garber-Wellington interval of the COA.

Water-quality assessments for parts of the COA, however, document arsenic concentrations above this standard. Based on the work of Schlottmann et al. (1998), concentrations of arsenic tend to occur in sandstone layers that are isolated between thick layers of mudstone. As a means to evaluate various approaches to arsenic remediation during well construction, we are developing a lithofacies and stratigraphic conceptual model for the Permian (Leonardian) Garber Sandstone. Detailed study of outcrops in Cleveland County and surrounding area has resulted in identification of nine lithofacies. The sandstone lithofacies include 1) massive, 2) ripple-laminated, 3) sandstone with horizontal to low angle planar laminations, and 4) tabular and trough cross-bedded sandstone, some with mud rip-up clasts. Other lithofacies include 5) carbonate clast conglomerate, 6) mud clast conglomerate, 7) iron stone, 8) shale/siltstones, and 9) blocky mudstones. These lithofacies and lithofacies associations provide the foundation for construction of lithofacies maps, vertical stratigraphic profiles, and paleoenvironmental reconstructions. A fluvial depositional setting for the Garber Sandstone is supported by the presence of lenticular-shaped sandstone bodies, erosional truncation of underlying units, fining upward grain-size profiles, and rapid lateral changes in the proportion of sandstone and shale. These findings are being used to constrain the habitat of arsenic in the aquifer system and as input to regional flow modeling.

EPA's research program provides data and support for building a science knowledge base to manage ecological resources, and reduce environmental risks. Oil-and-gas-related research is conducted at EPA's NRMRL and NCER. NRML's Superfund Innovative Technology Evaluation (SITE) Program has developed a phytoremediation process applicable for soils, sediments, and groundwater containing intermediate levels of organic contaminants. This process uses species of grasses, such as alfalfa and fescue, and soil nutrients to meet site's remedial goals. This process also uses deep-rooted, water-loving trees such as poplar to intercept groundwater plumes and reduce contaminant levels. A portable, compact gas chromatograph was designed and evaluated for on-site analysis of soil, water, and gas samples for organic compounds. Under NCER's Science to Achieve Results (STAR) program, the Integrated Petroleum Environmental Consortium is conducting research on phytoremediation, and bioremediation. Studies on phytoremediation have demonstrated that the use of long long-lived perennial plants provides an ecologically sound means of inexpensive, sustained remediation of contaminated soil. Sulfate amendment was demonstrated as a viable bioremediation technology in enhancing microbial sulfate reduction to in hydrocarbon-contaminated aquifers. NCER's research at the Oil Spills Research Center at Lake Charles, LA is directed at wetlands restoration, and the environmental effects of oil spills. A project under this program resulted in discovering a submerged plant that provides habitat, nursery, and food source for economically important flora and fauna.

The linear compounds consist primarily of the short-chain homologues (C (sub 10) -C (sub 20) ). The C (sub 27) -C (sub 29) sterols detected were dominated by C (sub 27) stenols. The molecular characteristics suggest that algae and bacteria were the major source organism. The presence of abundant fatty acid glycerol monoesters suggests that the biological lipids, particularly bacterial phospholipids were important contributors to the formation of the crude oils studied. The existence of abundant unsaturated linear compounds, stenols and high CPI values of linear non-hydrocarbon compounds is consistent with the low maturity of these crude oils.

However, complex questions with few answers surround the unknowns regarding the potential for environmental or human health effects from trace levels of xenobiotics in ground water, especially ground water augmented with treated waste water. Public acceptance for direct or indirect ground water recharge using treated municipal waste water (especially sewage) spans the spectrum from unquestioned embrace to outright rejection. In this paper, I detour around the issues most commonly discussed regarding ground water recharge and instead focus on some of the less-recognized issues--those that emanate from the mysteries created at the many literal and virtual interfaces involved with the subsurface world. My major objective is to catalyze discussion that advances our understanding of the barriers to public acceptance of waste water reuse with its ultimate culmination in direct reuse for drinking. I pose what could be a key question as to whether much of the public's frustration or ambivalence in its decision-making process for accepting, or rejecting, water reuse (for various purposes including personal use) emanates from fundamental inaccuracies, misrepresentation, or oversimplification of what water is and how it functions in the environment--just exactly what the water cycle is. These questions suggest it might behoove us to revisit some very elementary aspects of our science and how we are conveying them to the public.

AN - 51153343; 2004-061207 AB - A proof-of-concept experiment was devised to determine if pharmaceuticals and other organic waste water compounds (OWCs), as well as pathogens, found in treated effluent could be transported through a 2.4 m soil column and, thus, potentially reach ground water under recharge conditions similar to those in arid or semiarid climates. Treated effluent was applied at the top of the 2.4 m long, 32.5 cm diameter soil column over 23 days. Samples of the column inflow were collected from the effluent storage tank at the beginning (T (sub begin) ) and end (T (sub end) ) of the experiment, and a sample of the soil column drainage at the base of the column (B (sub end) ) was collected at the end of the experiment. Samples were analyzed for 131 OWCs including veterinary and human antibiotics, other prescription and nonprescription drugs, widely used household and industrial chemicals, and steroids and reproductive hormones, as well as the pathogens Salmonella and Legionella. Analytical results for the two effluent samples taken at the beginning (T (sub begin) ) and end (T (sub end) ) of the experiment indicate that the number of OWCs detected in the column inflow decreased by 25% (eight compounds) and the total concentration of OWCs decreased by 46% while the effluent was in the storage tank during the 23-day experiment. After percolating through the soil column, an additional 18 compounds detected in T (sub end) (67% of OWCs) were no longer detected in the effluent (B (sub end) ) and the total concentration of OWCs decreased by more than 70%. These compounds may have been subject to transformation (biotic and abiotic), adsorption, and (or) volatilization in the storage tank and during travel through the soil column. Eight compounds--carbamazapine; sulfamethoxazole; benzophenone; 5-methyl-1H-benzotriazole; N, N-diethyltoluamide; tributylphosphate; tri(2-chloroethyl) phosphate; and cholesterol--were detected in all three samples indicating they have the potential to reach ground water under recharge conditions similar to those in arid and semiarid climates. Results from real-time polymerase chain reactions demonstrated the presence of Legionella in all three samples. Salmonella was detected only in T (sub begin) , suggesting that the bacteria died off in the effluent storage tank over the period of the experiment. This proof-of-concept experiment demonstrates that, under recharge conditions similar to those in arid or semiarid climates, some pharmaceuticals, pathogens, and other OWCs can persist in treated effluent after soil-aquifer treatment.

Laboratory investigations involved both batch reactors using biologically active sand and continuous flow simulated aquifer storage and recovery experiments. All laboratory experiments were conducted using Colorado River water spiked with various target compounds at concentrations between 10 and 100 ng/L. Field studies were also conducted to determine the occurrence and attenuation of target compounds in water reuse applications. Two golf courses irrigated with reuse water were studied to determine if turf applications led to contamination of nearby ground water. A waste water treatment facility that uses rapid infiltration basins seasonally was also tested to determine the degree of attenuation of detectable target compounds along a subsurface flowpath. A qualitative structural activity relationship model was applied to the target compounds to predict the general rate of aerobic biological degradation. Significant attenuation of many target compounds was observed in both laboratory and field experiments. Conversely, several compounds displayed limited removal during these studies. Field experiments were limited to detectable compounds and various nonbiological removal or concentration effects that may impact data interpretations, which are discussed in this paper. The predictive model was found to be moderately accurate within the confines of the project scope.

The specific objectives of the results reported here were (1) to evaluate the use of rebound analysis of soil gas concentrations as the basis for operational strategies, and (2) establish the endpoint criteria for active remedial action. Three soil gas TCE concentration rebound tests were conducted over a period of 18 months to assess system performance and progress. For each rebound test, the system was shut down and allowed to equilibrate for two to four weeks. Soil gas TCE concentrations were measured several times during this equilibration period. Comparison of these rebound test results has been used for evaluating SVE system performance. A transient two-dimensional diffusion model has been used to convert soil gas TCE rebound concentrations to estimates from distance to source, and the model predictions correspond with observed dense nonaqueous phase liquid at the site. Also, these rebound tests can provide sufficient information about contaminant distribution and SVE mass transfer limitations to select a reasonable and appropriate endpoint for active remedial operations.

The propane injection resulted in degradation of a mixture of chlorinated solvents, including trichloroethylene (TCE), cis-dichloroethylene (c-DCE), and 1,1,1-trichloroethane (TCA). In only 20 d, the propane injection resulted in decreases of TCE and c-DCE of >98%, and a decrease in TCA in soil gas by approximately 70%. The degradation of the TCA may not have occurred with a methane, butane, toluene, or phenol injection. These decreases in chlorinated solvent concentrations were accompanied by large increases in propane-utilizing bacteria that ranged from below detection levels prior to the injection to approximately 1% of the ending total aerobic heterotrophic population by the end of the propane injection. Thus, a proportional increase occurred as heterotrophic counts increased a hundredfold. Microbial TCE degradation activity, as measured in microcosms, also increased with the propane injection. The highest rates of degradation were observed in microcosms with propane and nutrients, indicating the potential for higher field rates of degradation with nutrient additions.

Because future contaminant releases are likely it is necessary that local water managers develop release scenarios so as to be prepared prior to an actual contaminant release occurring. Release scenarios may be forecasted using appropriate historical data or they may be predicted using selected measured parameters. Forecasting contaminant releases to drinking-water supplies in karstic terranes is best accomplished by conducting numerous tracer tests from each potential source location to each exposure point so that acceptable solute-transport parameters for each solution conduit may be estimated from analyses of the breakthrough curves. Compositing the numerous breakthrough curves and fitting a quintic spline allows development of a single representative breakthrough curve that may then be used to forecast the effects of a release. Predicting contaminant releases is accomplished by combining basic measured field parameters for selected solution conduits in functional relationships for application in solute-transport models. The resulting breakthrough curve and solute-transport parameters can be used to predict the effects of a release. The forecasting and prediction methodologies were tested using a hypothetical release into a solution conduit developed in a karstic aquifer. Both methods were shown to produce reasonably acceptable results. The prediction methodology produced better time-of-travel results and better mass recovery and exposure concentration results than did the forecasting methodology.

The change of surface water quality is one of the main indicators used for the assessment of impacts on the environment. This paper investigates possibilities for employing MIKE 11 model in prediction and assessment of the change of surface water quality in the rivers, where power plants exist or may be built. The described methodology is used for evaluation of the effects of proposed for the construction hydro power plants on the quality of the Nemunas River.

Salamanders also can provide an important service to humans through their use as cost-effective and readily quantifiable metrics of ecosystem health and integrity. The diverse ecological roles of salamanders in natural areas underscore the importance of their conservation.

Measurements were made of semivolatile products of incomplete combustion (PICs), polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs), and mixed bromo-chloro dibenzo-p-dioxins and furans (PXDDs/Fs). A statistical analysis of the data has been performed so that variability in the PCDDs/Fs can be accounted for by variation in the semivolatile PICs, particularly the chlorobenzenes (CBz) and chlorophenols (CPh). In addition, a statistical analysis was performed to investigate the variability of the PXDDs/Fs as a function of the concentrations of the semivolatile chlorinated, brominated, and mixed bromo-chloro organics.

Blumm & William Warnock's Roads Not Taken: EPA vs. Clean Water, by Clifford J. Villa AN - 19430718; 6101364 AB - As a fan of Environmental Law and the federal Clean Water Act, it was with great interest that I received the symposium issue, The Clean Water Act Turns 30: Celebrating Its Past, Predicting Its Future. Unfortunately, in the articles that followed, celebrating and predicting appeared mighty scarce. To be sure, there is much cause for celebrating the gains in water quality since the modern Clean Water Act was passed in 1972. To be equally sure, the Clean Water Act has fallen short of the lofty goals that Congress originally set for it. Seeing only the failure, however, Michael C. Blumm and William Warnock set out to pin the blame on one agency with their symposium contribution Roads Not Taken: EPA vs. Clean Water. This Letter is not offered as a full response to Blumm and Warnock. Backed by the editors of Environmental Law, the authors may be trusted with their summaries of cases and points of fact. Rather, this Letter reflects on some of the unsupported conclusions of Blumm and Warnock that may detract, in my opinion, from what I take as the common goal of achieving clean water.

Cyclodextrin could increase significantly the degradation bacterial durability concentration on nitrobenzene, shorten the bacterial retention time, promote the growth of the degradation bacterial and accelerate the degradation of nitrobenzene. This function was related with the concentration of cyclodextrin and nitrobenzene. When the concentration of nitrobenzene was more than the durable concentration of the degradation bacteria the influence was more remarkable. The higher the concentration of cyclodextrin, the greater the influence.

In the United States, one possible route of environmental exposure to organotins (specifically dibutyltin and triphenyltin) is via fresh surface waters and fish taken from those waters. A unique methodology was used for quantitative and speciation of the organotins. This green-chemistry method combines two extraction techniques (solid-phase extraction for waters; hexane/tropolone extraction for fish) with mu -liquid chromatography-electrospray/ion trap mass spectrometry ( mu -LC-ES/ITMS) as the detection method. A small survey looking for organotins in fresh surface waters across the United States, and fish from those waters, was conducted. Various concentrations of dibutyltin and triphenyltin were detected in fresh water, ranging from nondetect to 2 ppb, and nondetect to 6 ppb, respectively.

A critical review of the technical literature is performed; a new estimate for the diffusivity of elemental mercury in water is obtained; a Setschenow coefficient for elemental mercury is published; and a normalized version of the Cole and Caraco (1998) low to intermediate windspeed air/water gaseous exchange model is developed. Findings from the study include: (1) some previously published estimates of elemental mercury diffusivity in water are likely too high by as much as a factor of four; (2) some published Schmidt number estimates are likely too low (by a similar factor); (3) some previously published elemental mercury air/water exchange estimates are likely too high; (4) overall water side environmental mass transfer coefficients for elemental mercury likely lie within the range 0.006 to 0.45 m/h; (5) there are both experimental and theoretical justifications for using a non-isothermal Henry's Law Constant in environmental systems over typical diel time periods; and (6) more complex non-isothermal Henry's Law Constants may be required to model air/water gaseous exchange in hydrothermal and/or industrial systems.

Community-based exposure assessments have the potential to be an effective way to address these concerns. The success of such studies depends critically on the effective translation and communication of study results back to the study participants and the community. In this article we describe the communication approach applied as part of the South Baltimore Community Exposure Study. Specifically, in conjunction with collecting measurements, we asked the community to define questions they wanted answered and the way in which they wanted to receive study results. To meet their needs, we applied the risk assessment framework. The approach we developed helped residents interpret exposure assessment measurements and gave them the raw materials to effect change in their community. The risk-based approach to presenting participant and community results provides the means to move beyond traditional reporting of concentration values in three important ways. First, risk takes into consideration toxicity, thereby enabling a dialogue about community health concerns. Second, risk provides a common denominator so that exposure and risk can be compared and priorities identified. Third, exposure and risk can be summed, thereby meeting the community's need for information regarding cumulative exposure. This approach may be a useful model for other researchers conducting exposure assessments in response to community concerns.

The 4-amino-MX (AMX) and 2-amino-MK (AMK) metabolites have been detected in trout fish hemoglobin (Hb) samples by gas chromatography-ion trap-mass spectrometry (GC-MS). Twelve Hb samples prepared from rainbow trout that were exposed to MX and MK, over a period of 24 and 72 h, were analyzed. Amino metabolites were liberated by basic hydrolysis and extracted from the fish Hb into n-hexane. The extract was concentrated, analyzed, and spiked with a standard solution (80 pg/ mu l) of AMX or AMK and reanalyzed. Concentrations of AMX from 10 to 25 ng/g were detected in Hb from fish taken 24 and 72 h after MX exposure. At 24 and 72 h after MK exposure, the concentration of AMK was found to be 25-51 ng/g and 9.5-25 ng/g, respectively. Concentrations of AMK in Hb from two of the three trout were substantially lower after 72 h compared with 24 h exposure. The AMX and AMK metabolites were not detected in four control samples. Average recoveries exceeding 89 and 86% could be achieved for AMX and AMK, respectively, with a coefficient of variation (CV) around 5%.

The present study was conducted to determine if the unanticipated estrogenic effects are produced by conversion of MT via aromatase activity to 17 alpha -methylestradiol (ME2). Aromatase activity at the end of a 7-day waterborne MT exposure (20, 200 mu g/l) was significantly decreased in ovarian microsomes and brain homogenates from exposed fish, to about 30-50% of control activity. Although aromatase activity was decreased by 7 days, it is possible that the conversion of MT to ME2 occurred soon after initial exposure. In support of this, ME2 was detected in plasma samples of the fish following the 7-day exposure, confirming their ability convert the androgen MT to the estrogen ME2. The concentration of ME2 in plasma was within the range of plasma 17'-estradiol (E2) found in control female fathead minnows (4-5 ng/ml). These results, in conjunction with competitive binding assays that indicate ME2 binds to the fathead minnow estrogen receptor with a relative binding affinity of 68.3% of E2, support the hypothesis that aromatization of MT to ME2 contributes to the estrogenic effects in fathead minnows following exposure to this androgen JF - Aquatic toxicology AU - Hornung, M W AU - Jensen, K M AU - Korte, J J AU - Kahl, MD AU - Durhan, E J AU - Denny, J S AU - Henry, T R AU - Ankley, G T AD - United States Environmental Protection Agency, Mid-Continent Ecology Division, 6201 Congdon Blvd., Duluth, MN 55804 USA, hornung.michael@epa.gov Y1 - 2004 PY - 2004 DA - 2004 SP - 15 EP - 23 VL - 66 IS - 1 SN - 0166-445X, 0166-445X KW - Fathead minnow KW - ASFA 3: Aquatic Pollution & Environmental Quality KW - Pimephales promelas KW - Vitellogenesis KW - Androgenesis KW - Freshwater KW - Sex hormones KW - Q5 08504:Effects on organisms UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/19322584?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%3Aasfaaquaticpollution&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Aquatic+toxicology&rft.atitle=Mechanistic+basis+for+estrogenic+effects+in+fathead+minnow+%28Pimephales+promelas%29+following+exposure+to+the+androgen+17+alpha+-methyltestosterone%3A+conversion+of+17+alpha+-methyltestosterone+to+17+alpha+-methylestradiol&rft.au=Hornung%2C+M+W%3BJensen%2C+K+M%3BKorte%2C+J+J%3BKahl%2C+MD%3BDurhan%2C+E+J%3BDenny%2C+J+S%3BHenry%2C+T+R%3BAnkley%2C+G+T&rft.aulast=Hornung&rft.aufirst=M&rft.date=2004-01-01&rft.volume=66&rft.issue=1&rft.spage=15&rft.isbn=&rft.btitle=&rft.title=Aquatic+toxicology&rft.issn=0166445X&rft_id=info:doi/10.1016%2Fj.aquatox.2003.06.004 L2 - http://www.elsevier.com/locate/aqtox LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2006-09-01 N1 - SuppNotes - Physical medium: Printed matter, Internet; http://www.elsevier.com/locate/aquatox N1 - Last updated - 2014-05-07 N1 - SubjectsTermNotLitGenreText - Vitellogenesis; Androgenesis; Sex hormones; Pimephales promelas; Freshwater DO - http://dx.doi.org/10.1016/j.aquatox.2003.06.004 ER - TY - JOUR T1 - Effects of restraint stress in gestation: Implications for rodent developmental toxicology studies AN - 19271340; 5846541 AB - Restraint has been used as a procedure to study the effects of stress on gestation outcome in rodents. The effects of restraint could potentially be used as a model for the impact of general stress produced by high doses of toxicants and other interventions. In mice, restraint in the peri-implantation period leads to implantation failure, and restraint at appropriate times in organogenesis produces cleft palate, supernumerary ribs, and resorption. In rats, there is some evidence for an association with restraint for implantation failure, but not for the morphological anomalies. Restraint in late gestation alters adult sexual behavior of male rat offspring, but consequences for their fertility are not known. Intrauterine growth retardation is not commonly associated with gestational restraint. In the few studies where they have been directly compared, different restraint procedures produced graded, qualitatively different, or no effects. Adrenocortical hormones have been implicated as mediating the effect of restraint on cleft palate, but not on supernumerary ribs, implantation failure, or sexual differentiation. Given the variety of restraint procedures and the varying species-dependent consequences, it is not possible to infer a generalizable pattern of developmental effects due to gestational stress from the restraint literature. As an alternative approach, contemporary methods in gene expression and developmental biology could profitably be applied to understanding different patterns of stress-mediated effects of toxicant exposures on intrauterine development.

We induced dose- related increases in SNR in fetal CD-1 mice by treating on gestation days 7-8 with benomyl (BEN; 0, 75, 150 mg/kg/d), dinoseb (DIN; 0, 30, 50 mg/kg/d); 2- methoxyethanol (2-ME; 0, 75, 150 mg/kg/d), or valproic acid (VPA; 0, 125, 250 mg/kg/d). Incidences of SNR were 9.3-27.6% in controls and 19.3-84.4% in the high dosage groups. SNR length showed a bimodal distribution with peaks at 0.3- 0.4 mm and 0.9-1.1 mm in both treated and control groups. Based on length distributions, we used an actual length of 0.6 mm to separate short (rudimentary) from long (extra) SNR. DIN, 2-ME, and VPA induced a dose-related increase of extra ribs, while the incidence of rudimentary ribs remained at control levels. There was no apparent correlation of the presence of either type of SNR in a fetus and the occurrence of other anomalies. These data support the idea that extra and rudimentary SNR may reflect separate developmental phenomena, and should be considered and reported separately in developmental toxicity studies for risk assessment.

These tolerance values have been used effectively to assess the biological condition of running waters. Generalised additive models were used to associate the presence and absence of different macroinvertebrate genera with different environmental gradients. The model results were then used to classify each genera as sensitive, intermediately tolerant or tolerant to different stressor gradients as quantified by total phosphorus concentration, sulphate ion concentration, qualitative habitat score and stream pH. The analytical approach provided a means of estimating stressor-specific tolerance classifications while controlling for covarying, natural environmental gradients. Computed tolerance classification generally conformed with expectations and provided some capacity for distinguishing between different stressors in test data.

AN - 18051067; 5994050 AB - In the northwestern United States, there is considerable interest in the recovery of Pacific salmon (Oncorhynchus spp.) populations listed as threatened or endangered. A critical component of any salmon recovery effort is the improvement of stream habitat that supports various life stages. Two factors in concert control the ability to detect consistent change in habitat conditions that could result from significant expenditures on habitat improvement: the magnitude of spatial and temporal variation and the design of the monitoring network. The important components of variation that affect trend detection are summarized here, and how well-designed networks of 30-50 sites monitored consistently over years can detect underlying changes of 1-2% per year in a variety of key habitat characteristics within 10-20 years, or sooner, if such trends are present is explained. The importance of the duration of surveys for trend detection sensitivity is emphasized because the power to detect trends improves substantially with the passage of years.

We tested this idea with 58 pairs of small estuaries (<260 km super(2)) and watersheds in the U.S. Mid-Atlantic coastal plain (Delaware Bay to Chesapeake Bay). We considered 34 landscape metrics as potential explanatory variables and seven estuarine parameters as response variables. We developed three logistic regression models: one to calculate the probability of degraded benthic environmental quality (BEQ), as defined by chemical parameters, and two for the probability of degraded estuarine bottom communities, one using a benthic index (BI) and a second using the total number of bottom-dwelling species (TNBS, consisting of benthic macroinvertebrates and fishes). We evaluated the discriminatory power of the models with ROC (receiver operating characteristic) curves of sensitivity and specificity. All three models showed excellent discrimination of high and low values. A model using the sum of all human land uses and percent wetlands correctly classified BEQ in 86% of the cases; low benthic index and low total number of bottom species were each associated with degraded BEQ (p < 0.01). The BI model used percent riparian urban, riparian wetlands, and agriculture on steep slopes (76% correct classification) and correctly predicted high-low benthic index of an independent data set 79% of the time (p < 0.05). The TNBS model used percent wetlands, riparian wetlands, and riparian agriculture (74% correct classification). Watersheds with higher percentages of urban and agricultural land uses were associated with lower benthic environmental quality, benthic index, and biodiversity, whereas those with higher percentages of wetlands were associated with higher numbers. As human development of watersheds increases, statistical prediction rules developed from landscape metrics could be a cost-effective method to identify potentially threatened estuaries.

Within a marsh, its location and relative size are governed largely by the degree of flooding by seawater. Iva's wide distribution and restricted location within salt marshes may make it a useful indicator of overall conditions of the marshes. This work was designed to provide basic information on the age and growth of I. frutescens, especially as they relate to the degree of flooding that is needed in order to investigate Iva's potential as an indicator. Cross- sections of older stems (living and standing dead) from salt marshes in Rhode Island, United States, were examined in order to age stems and estimate their growth rate from cumulative increase in woody tissue. Most stems were six yr old or less, suggesting that aboveground structures live for only a few years. Stem diameter correlated with growth rate and aboveground biomass. Elevation at the root zone was used to estimate the duration that plants were flooded, which was negatively correlated with stem diameter. The most robust plants came from sites that were flooded only up to 6-7% of the total time during the growing season. No plants were found in areas flooded more than 30% of the time.

Exposure to particles occurs mostly indoors, where a main removal mechanism is deposition to surfaces. Deposition can be affected by the use of forced-air circulation through ducts or by air filters. In this study, we calculate the deposition rates of particles in an occupied house due to forced-air circulation and the use of in-duct filters such as electrostatic precipitators (ESP) and fibrous mechanical filters (MECH). Deposition rates are calculated for 128 size categories ranging from 0.01 to 2.5 mu m. More than 110 separate 'events' (mostly cooking, candle burning, and pouring kitty litter) were used to calculate deposition rates for four conditions: fan off, fan on, MECH installed, ESP installed. For all cases, deposition rates varied in a 'U'- shaped distribution with the minimum occurring near 0.1 mu m, as predicted by theory. The use of the central fan with no filter or with a standard furnace filter increased deposition rates by amounts on the order of 0.1-0.5 h super(-1). The MECH increased deposition rates by up to 2 h super(-1) for ultrafine and fine particles but was ineffective for particles in the 0.1-0.5 mu m range. The ESP increased deposition rates by 2-3 h super(-1) and was effective for all sizes. However, the ESP lost efficiency after several weeks and needed regular cleaning to maintain its effectiveness. A reduction of particle levels by 50% or more could be achieved by use of the ESP when operating properly. Since the use of fans and filters reduces particle concentrations from both indoor and outdoor sources, it is more effective than the alternative approach of reducing ventilation by closing windows or insulating homes more tightly. For persons at risk, use of an air filter may be an effective method of reducing exposure to particles.

We evaluated methanol-induced pathogenesis in CD-1 and C57BL/6J embryos exposed during gastrulation in whole embryo culture. Conceptuses with five to seven somites were exposed to 0, 1, 2, 3, 4, or 6 mg methanol/ml culture medium for 24 hr and embryonic morphology was assessed. Cell death was evaluated by histology and LysoTracker red staining, and cell-cycle distribution was evaluated by flow cytometry. In C57BL/6J embryos, craniofacial defects were observed at 3 mg methanol/ml and greater. The response for CD-1 embryos was different, with increased dysmorphology only at 6 mg/ml. However, protein content in CD-1 embryos was reduced at 3 mg methanol/ml and above, indicating growth retardation. Yolk sac toxicity occurred only at 6 mg methanol/ml in both strains. Methanol caused only small changes in cell-cycle distribution, while cell death was induced at 4 and 6 mg methanol/ml in both strains after 8 hr. The extent of cell death after 8 hr was greater in C57BL/6J embryos, and increased over time through 18 hr; in contrast, CD-1 embryos showed less cell death at 18 than at 8 hr, suggesting recovery. Cell death plays a prominent role in methanol-induced dysmorphogenesis, while cell-cycle perturbation may not. Differences in the extent of cell death between CD-1 and C57BL/6J embryos correlated with differences in the severity of dysmorphogenesis. Published 2004 Wiley-Liss, Inc.

We describe dysmorphogenesis, cell death, cell cycle assessment, and effects on development of cranial ganglia and nerves observed following administration of methanol to pregnant C57BL/6J mice on gestation day (GD) 7. Mice were injected (i.p.) on GD 7 with 0, 2.3, 3.4, or 4.9 gm/kg methanol, split into two doses. In embryos of mice treated with 0 or 4.9 gm/kg methanol, we used histology and LysoTracker red staining on GD 8 0 hr through GD 8 18 hr to examine cell death and dysmorphogenesis, and we also evaluated cell- cycle distribution and proliferation using flow cytometry (FCM) and BrdU immunohistochemistry. On GD 10, we evaluated the effect of GD 7 exposure to 0, 2.3, 3.4, or 4.9 gm/kg methanol on cranial ganglia and nerve development using neurofilament immunohistochemistry. Methanol treatment on GD 7 resulted in reduced mesenchyme surrounding the fore- and midbrain, and in the first branchial arches, by GD 8 12 hr. There were disruptions in the forebrain neuroepithelium and optic pit. Neural crest cell emigration from the mid- and hindbrain region was reduced in methanol-exposed embryos. Methanol had no apparent effect on BrdU incorporation or cell-cycle distribution on GD 8. Cell death was observed in the hindbrain region along the path of neural crest migration and in the trigeminal ganglion on GD 8 18 hr. Development of the cranial ganglia and nerves was adversely affected by methanol. Development of ganglia V, VIII, and IX was decreased at all dosage levels; ganglion VII was reduced at 3.4 and 4.9 gm/kg, and ganglion X was reduced at 4.9 gm/kg. These results suggest that gastrulation-stage methanol exposure affects neural crest cells and the anterior mesoderm and neuroepithelium. Cell death was evident in areas of migrating neural crest cells, but only at time points after methanol was cleared from the embryo, suggesting an indirect effect on these cells.

C57BL/6J fetuses exhibit the holoprosencephaly spectrum of malformations after maternal exposure to ethanol during gastrulation, but the sensitivity of C57BL/6J mice to methanol- induced teratogenesis has not been previously described. Pregnant C57BL/6J mice were administered two i.p. injections totaling 3.4 or 4.9 g/kg methanol or distilled water four hrs apart on gestation day 'GD' 7. On GD 17, litters were examined for numbers of live, dead and resorbed conceptuses, fetuses were weighed as a litter and examined externally, and all fetuses were double stained for skeletal analysis. No maternal intoxication was apparent, but the high dosage level caused a transient deficit in maternal weight gain. The number of live fetuses per litter was reduced at both dosages of methanol, and fetal weight was lower in the high dosage group. Craniofacial defects were observed in 55.8% of fetuses in the low dosage group and 91.0% of fetuses in the high dosage group, including micro/anophthalmia, holoprosencephaly, facial clefts and gross facial angenesis. Skeletal malformations, particularly of the cervical vertebrae, were observed at both dosages of methanol, and were similar to those previously reported in the CD-1 mouse following methanol exposure. The types of craniofacial malformations induced in the C57BL/6J mouse by methanol indicate that methanol and ethanol have common targets and may have common modes of action.

The model was developed and optimized for sediments in Thalassia testudinum seagrass beds of Lower Laguna Madre, Texas, U.S., and is composed of a plant submodel and a sediment diagenetic submodel. Simulations were developed for a natural stressor (harmful algal bloom, Aureoumbra lagunensis) and an anthropogenic stressor (dredging event). The observed harmful algal bloom (HAB) was of limited duration and the simulations of that bloom showed no effect of the algal bloom on biomass trends but did suggest that sediment sulfides could inhibit growth if the bloom duration and intensity were greater. To examine this hypothesis we ran a simulation using data collected during a sustained 4-yr bloom in Upper Laguna Madre. Simulations suggested that light attenuation by the HAB could cause a small reduction in T. testudinum biomass, while input of organic matter from the bloom could promote development of a sediment geochemical environment toxic to T. testudinum leading to a major reduction in biomass. A 3-wk dredging event resulted in sedimentation of a layer of rich organic material and reduction of canopy light for a period of months. The simulations suggested that the seagrass could have recovered from the effects of temporary light reduction but residual effects of high sulfides in the sediments would make the region inhospitable for seagrasses for up to 2.5 yr. These modeling exercises illustrate that both natural and anthropogenic stressors can result in seagrass losses by radically altering the sedimentary geochemical environment.

The goal was to use four ecological indicators (number of species, abundance, biomass, and fish and crab prey abundance) to detect differences among four intertidal habitats in Willapa Bay, Washington, United States. The four habitats were eelgrass (Zostera marina), Atlantic cordgrass (Spartina alterniflora), mud shrimp (Upogebia pugettensis), and ghost shrimp (Neotrypaea californiensis). Four sample unit areas (0.005, 0.010, 0.015, and 0.020 m super(2)), two sample unit depths (0-5 and 0-10 cm), and two sieve mesh sizes (1.0 and 0.5 mm) were evaluated. The optimal sampling protocol was defined as the least costly protocol capable of reliably (statistical power, 1 - beta => 0.80) detecting significant (alpha = 0.05) differences among => 4 of the 6 pairwise habitat contrasts by ANOVA on all four ecological indicators. The relative cost of each sampling protocol was estimated as a direct function of the sample unit size and number and the cost-in-processing-time ratios of 1 (5 cm deep):1.7 (10 cm deep) and 1 (=> 1.0 mm macrofauna size fraction):2.5 (=> 0.5 mm macrofauna size fraction), which were taken from previous studies. The optimal sampling protocol was 15-20, 0.01-m super(2) x 5-cm deep, 0.5-mm mesh samples per habitat.

Nekton density and biomass were compared with a 1.75-m super(2) drop ring at 3 sites (marsh, intertidal, and subtidal) in Coggeshall Cove in Narragansett Bay and two subtidal sites (eelgrass and macroalgae) in Ninigret Pond, a coastal lagoon. We collected benthic core samples and examined nekton stomach contents in Coggeshall Cove. We identified 16 species of fish, 16 species of crabs, and 3 species of shrimp in our drop ring samples. A multivariate analysis of variance indicated differences in total nekton, invertebrates, fish, and winter flounder across the five sites. Relative abundance of benthic invertebrate taxa did not match relative abundance of prey taxa identified in the stomachs. Nonmetric multidimensional scaling plots showed groupings in nekton and benthic invertebrate prey assemblages among subtidal, intertidal, and marsh sites in Coggeshall Cove. Stepwise multiple regression indicated that biomass of macroalgae was the most important variable predicting abundance of nekton in Coggeshall Cove, followed by elevation and depth. In Rhode Island systems that do not experience chronic hypoxia, macroalgae adds structure to unvegetated areas and provides refuge for small nekton. All sites sampled were characterized by high abundance and diversity of nekton pointing to the importance of shallow inshore areas for production of fishes and decapods. Measurements of habitat quality should include assessment of the functional significance of a habitat (this can be done by comparing nekton numbers and biomass), some measure of habitat diversity, and a consideration of how habitat quality varies in time and space.

Several causes of action still remain, however, that can be an effective means of achieving environmental justice. This Article will explore these causes of action and show that each has unique characteristics and can present distinct opportunities. This Article will also address the importance of tailoring environmental justice claims to best suit the plaintiff. Finally, this Article will present a case study of a proposal to build a geothermal power plant in an area of California that is sacred to Native Americans, and suggest an effective strategy for bringing an environmental justice claim.

The drainage system monitored ( similar to 90 km long) included an artificial drain, natural creek and river during the irrigation season, and the drain and creek during the non-irrigation season. During the irrigation season, enzyme-linked immuno-sorbent assay (ELISA) for molinate and passive samplers containing 2,2,4-trimethylpentane (TRIMPS) were also used to assess their relative merits in measuring and monitoring pesticide discharges. A wide range of pesticides were analysed, but during the irrigation season, only molinate and thiobencarb were frequently detected in the drain, associated with irrigated rice crops. These pesticides were also detected at the most upstream site of the receiving creek but not further downstream. During the non-irrigation season, atrazine and simazine were often detected in the drain, while dimethoate and glyphosate were occasionally detected. During the irrigation season, the passive samplers detected thiobencarb that was not detected from surface water samples. ELISA was regarded as a useful screening method for molinate, although the method showed higher concentrations of molinate than GC/MS analysis.

A system was designed to score endemic species and remote populations of plants, using an extensive herbarium database to set the spring flora in context. The sum of these indices for individual wetland complexes yielded a ranked score. The high priority wetland complexes (scoring five or greater) adequately represent their floristic composition, capture all endemic plant species and 76% of the flora. Although data are limited, many of the high value spring wetlands have endemic fauna of which the snails have been most thoroughly surveyed. The procedure provides direction for an efficient conservation program that if implemented should provide security against a range of threatening processes.

AN - 16165461; 5854884 AB - Brominated flame retardants (BFRs) have routinely been added to consumer products for several decades in a successful effort to reduce fire-related injury and property damage. Recently, concern for this emerging class of chemicals has risen because of the occurrence of several classes of BFRs in the environment and in human biota. The widespread production and use of BFRs; strong evidence of increasing contamination of the environment, wildlife, and people; and limited knowledge of potential effects heighten the importance of identifying emerging issues associated with the use of BFRs. In this article, we briefly review scientific issues associated with the use of tetrabromobisphenol A, hexabromocyclododecane, and three commercial mixtures of polybrominated diphenyl ethers and discuss data gaps. Overall, the toxicology database is very limited; the current literature is incomplete and often conflicting. Available data, however, raise concern over the use of certain classes of brominated flame retardants.

AN - 71435570; 14630409 AB - This paper presents the results of a national scale evaluation of the environmental impact of surface impoundments that contain non-hazardous wastewaters. In the 1990s, it was found that approximately 18,000 surface impoundments existed in the US for treating, storing or disposing of non-hazardous wastewater. In this study, the focus was on the subset of 11,900 impoundments that contain at least one of 256 chemicals of interest or high or low pH wastewater. Questionnaires were sent to facilities chosen in a two-phase nationally representative random sample. The nature, extent and use of surface impoundments across manufacturing industries were characterized using the information collected in the survey. Also, the chemical composition of impounded wastewaters; the potential for chemical releases to the environment from the impoundments; and the risk from these releases were assessed. It is estimated that only approximately 5-6% of facilities with impoundments have the potential to pose risks to human health, although approximately 19-46% of facilities with impoundments release chemicals of concern to the environment. The information in this study should help environmental managers evaluate and avoid those risk factors that have the potential to result in environmental harm, particularly when present in combination.

AN - 71471541; 14686339 AB - Epidemiologic evidence suggests that increased morbidity and mortality are associated with the concentrations of ambient air particulate matter (PM). Many sources contribute to the particulate fraction of ambient air pollution, including diesel exhaust particulates (DEP). Diesel exhaust also contributes gas-phase pollutants to the atmosphere, and gaseous copollutants may influence the toxicity of PM. The composition of diesel exhaust varies greatly depending on the engine load conditions as well as other factors. To determine whether different diesel exhaust composition can affect lung cell resposes, the effects of of diesel exhaust extracts derived from different engine loads were examined on normal human bronchial epithelial cells (NHBE) in vitro. Diesel exhaust was collected into chilled impingers containing phosphate-buffered saline (PBS). Cultured NHBE cells were treated with 0 to 500 microg/well extract from approximately 0% engine load (termed low load or LL) or extract from approximately 75% engine load (termed high load or HL) for 24 h. The HL extract was cytotoxic at 500 microg compared to controls as measured by (51)Cr release. Production of the neutrophil chemotaxin interleukin 8 (IL-8) was decreased 4.7-fold in cells treated with 500 microg LL extract, whereas cells treated with 500 microg HL extract showed a 2.4-fold increase in IL-8 release. Production of the inflammatory and immune system mediator prostaglandin E(2) (PGE(2)) was increased up to 2.5-fold in cells treated with HL extract, but unchanged with other treatments. Melittin stimulation of cells showed that the LL extract had an inhibitory effect on PGE(2) release at 500 microg. Differences in carbonyl content of the extracts were found by high performance liquid chromatography/mass spectroscopy HPLC/MS, with the HL extract having more intermediate size carbonyls (i.e. with six to nine carbons). The data suggest that the response of NHBE cells to treatment with diesel exhaust will vary depending on the constituent components of the exhaust.

AN - 71516113; 14717192 AB - Experimental data from a laboratory-scale wet scrubber simulator confirmed that oxidized mercury, Hg2+, can be reduced by aqueous S(IV) (sulfite and/or bisulfite) species and results in elemental mercury (HgO) emissions under typical wet FGD scrubber conditions. The S(IV)-induced Hg2+ reduction and Hg0 emission mechanism can be described by a model which assumes that only a fraction of the Hg2+ can be reduced, and the rate-controlling step of the overall process is a first-order reaction involving the Hg-S(IV) complexes. Experimental data and model simulations predict that the Hg2+ in the flue gas can cause rapid increase of Hg0 concentration in the flue gas across a FGD scrubber. Forced oxidation can enhance Hg2+ reduction and Hg0 emission by decreasing the S(IV) concentration in the scrubbing liquor. The model predictions also indicate that flue gas Hg0 increase across a wet FGD scrubber can be reduced by decreasing the pH, increasing S(IV) concentration, and lowering the temperature.

Particulate matter (PM) from Research Triangle Park (NC) was collected and separated into 3 different size fractions: coarse (CO; >3.5 mu m), fine (FI; 1.7-3.5 mu m), and fine/ultrafine (FU; < 1.7, mu m) using impaction and electrostatic precipitation. Particle chemistry indicated the presence of sulfates, zinc, iron, and copper in all fractions. CD1 mice were intratracheally instilled with 10, 50, or 100 mu g of each fraction. After 18h, the lungs were lavaged and assayed for signs of inflammation. All particles produced increases in neutrophil number, and this was highest in the high-dose FU group. Biochemical analysis revealed no change in lactate dehydrogenase (LDH) activity, and increased albumin and tumor necrosis factor (TNF)- alpha levels were only seen with the high-dose FI particles. Interleukin 6 (IL-6) levels were increased over control levels after treatment with 100 mu g of all 3 particle sizes. To determine whether oxidative stress may contribute to these effects, antioxidant levels in the lung were boosted by an intraperitoneal (ip) injection with dimethylthiourea (DMTU). This treatment resulted in a twofold increase in the total antioxidant capacity of the lung and decreased the PM-induced cytokine and neutrophil influx up to 50%. The data indicate that on an equal mass basis, ambient particles of these three size ranges produce pulmonary inflammation, and that increasing the antioxidant capacity of the lung reduces particle-induced cytokine and cellular responses.

Such estimates based on direct measurements are quite limited for tropical dry forests. The goal of this study was to assess the species composition and biomass density in an intact Mexican forest representative of the tropical dry forest biome. We then compared our measured biomass with biomass estimates computed with a published model in current use. A total of 72 species were found in a 0.5ha stand with a basal area of 31.3m super(2)ha super(-1). The dominant species, in terms of biomass, were Brosimum alicastrum Sw., Manilkara zapota (L.) Royen, Luehea speciosa Wildl., Pouteria unilocularis (Donn. Sm.) Baehni, Trichilia minutiflora Standl., and Spondias mombin Linn. Tree heights ranged up to 30m and dbh to 82.1cm. Species-specific biomass regression models were developed for the six most common species of large (>10cmdbh) trees and for the nine most common species of small (10cmdbh) trees from the destructive harvest of 698 trees. Mass of large trees (n=195) were used to derive the regression model Y=exp{-2.173+0.868ln(D super(2)TH)+0.0939/2}, where Y is the total dry weight (kg), D the dbh (cm), and TH the total height (m). Total aboveground tree biomass was estimated to be 225Mgha super(-1), and was dominated (85%) by the biomass of the large trees. The actual biomass of each of the 195 large trees was compared to individual tree biomass calculated with a published regression model [Estimating biomass and biomass change of tropical forests. A primer. FAO Forestry Paper 134. Food and Agriculture Organization of the United Nations, Rome, Italy, 1997] that is based on measurements of 29 trees. We found that the published model underestimated biomass of these trees by 31% (37.6 versus 54.4Mg). Calculated biomass was less than measured biomass for 29 of 33 species. The current study points to the value of site-specific assessment of aboveground biomass and may contribute to more accurate estimates of dry tropical forest biomass densities currently used to estimate greenhouse gas flux from land management activity.

AN - 71523932; 14737232 AB - This paper evaluates the chemical stability of four arsenosugars using tetramethylammonium hydroxide (TMAOH) as an extraction solvent. This solvent was chosen because of the near quantitative removal of these arsenicals from difficult to extract seafood (oysters and shellfish). Four arsenosugars (3-[5'-deoxy-5'-(dimethylarsinoyl)-beta-ribofuranosyloxy]-2-hydroxypropylene glycol--As(328), 3-5'-deoxy-5'-(dimethylarsinoyl)-beta-ribofuranosyloxy]-2-hydroxypropanesulfonic acid--As(392), 3-[5'-deoxy-5'-(dimethylarsinoyl)-beta-ribofuranosyloxy]-2-hydroxypropyl hydrogen sulfate--As(408), and 3-[5'-deoxy-5'-(dimethylarsinoyl)-beta-ribofuranosyloxy]-2-hydroxypropyl-2,3-hydroxypropyl phosphate--As(482)) were evaluated. The stability of these four arsenosugars were studied independently in a solution of 2.5% TMAOH at 60 degrees C over a period of up to 8 h. Two arsenosugars, As(328) and As(392), were found to be relatively stable in this solution for up to 8 h. However, As(408) and As(482) formed detectable quantities of dimethylarsinic acid (DMAA) and As(328) within 0.5 and 2 h, respectively. It was found that 97% of As(408) degrades after 8 h of treatment producing 3.4 times as much DMAA as As(328). This is contrary to As(482), which produces 13 times as much As(328) as DMAA and only 37% of the As(482) was converted by the 8 h treatment at 60 degrees C. These degradation products led to the investigation of weaker TMAOH extraction solvents. Three different concentrations (2.5%, 0.83% and 0.25%) were used to determine the effect of TMAOH concentration on the degradation rate of As(408). By reducing the TMAOH concentration to 0.83%, the conversion of the arsenosugar to As(328) and DMAA is nearly eliminated (less than 5% loss). Arsenosugars, As(408) and As(482), were also studied in 253 mM NaOH to verify the degradation products. The NaOH experiments were conducted to investigate a possible hydroxide based reaction mechanism. Similar degradation plots were found for each arsenosugar when compared to the 2.5% TMAOH data. A mechanism has been proposed for the formation of As(328) from As(408) and As(482) in base via an SN2 reaction (hydroxide attack) at the side chain carbon adjacent to the inorganic ester. The formation of DMAA is observed in all arsenosugars after prolonged exposure. This probably occurs via an SN2 attack at the arsenic atom.

AN - 71505320; 14680324 AB - The extent to which humans and wildlife are exposed to toxicants is an important focus of environmental research. This work has been directed toward the development of molecular indicators diagnostic for exposure to various stressors in freshwater fish. Research includes the discovery of genes, indicative of environmental exposure, in the Agency's long-established aquatic toxicological organism, the fathead minnow (Pimephales promelas). Novel cDNAs and coding sequences will be used in DNA microarray analyses for pattern identification of stressor-specific, differentially up- and down-regulated genes. The methods currently used to discover genes in this organism, for which few annotated nucleic acid sequences exist, are cDNA subtraction libraries, differential display, exploiting PCR primers for known genes of other members of the family Cyprinidae and use of degenerate PCR primers designed from regions of moderate protein homology. Single or multiple genes noted as being differentially expressed in microarray analyses will then be used in separate studies to measure bioavailable stressors in the laboratory and field. These analyses will be accomplished by quantitative RT-PCR. Moving from analysis of single gene exposures to the global state of the transcriptome offers possibilities that those genes identified by DNA microarray analyses might be critical components of dynamic biological systems and networks, wherein chemical stressors exert toxic effects through various modes of action. Additionally, the ability to discriminate bioavailability of stressors in complex environmental mixtures, and correlation with adverse effects downstream from these early molecular events, presents challenging new ground to be broken in the area of risk assessment.

Membrane bioreactor system for sulfate reduction. AN - 71459750; 14669874 AB - Several biotreatmemt techniques for sulfate conversion by the sulfate reducing bacteria (SRB) have been proposed in the past, however few of them have been practically applied to treat sulfate containing acid mine drainage (AMD). This research deals with development of an innovative polypropylene hollow fiber membrane bioreactor system for the treatment of acid mine water from the Berkeley Pit, Butte, MT, using hydrogen consuming SRB biofilms. The advantages of using the membrane bioreactor over the conventional tall liquid phase sparged gas bioreactor systems are: large microporous membrane surface to the liquid phase; formation of hydrogen sulfide outside the membrane, preventing the mixing with the pressurized hydrogen gas inside the membrane; no requirement of gas recycle compressor; membrane surface is suitable for immobilization of active SRB, resulting in the formation of biofilms, thus preventing washout problems associated with suspended culture reactors; and lower operating costs in membrane bioreactors, eliminating gas recompression and gas recycle costs. Information is provided on sulfate reduction rate studies and on biokinetic tests with suspended SRB in anaerobic digester sludge and sediment master culture reactors and with SRB biofilms in bench-scale SRB membrane bioreactors. Biokinetic parameters have been determined using biokinetic models for the master culture and membrane bioreactor systems. Data are presented on the effect of acid mine water sulfate loading at 25, 50, 75 and 100 ml/min in scale-up SRB membrane units, under varied temperatures (25, 35 and 40 degrees C) to determine and optimize sulfate conversions for an effective AMD biotreatment. Pilot-scale studies have generated data on the effect of flow rates of acid mine water (MGD) and varied inlet sulfate concentrations in the influents on the resultant outlet sulfate concentration in the effluents and on the number of SRB membrane modules needed for the desired sulfate conversion in those systems. The pilot-scale data indicate that the SRB membrane bioreactors systems can be applied toward field-scale biotreatment of AMD and for recovery of high purity metals and an agriculturally usable water.

Metal precipitation for recovery and recycle. AN - 71453019; 14669873 AB - Acid mine drainage (AMD), an acidic metal-bearing wastewater, poses a severe pollution problem attributed to post mining activities. The metals usually encountered in AMD and considered of concern for risk assessment are arsenic, cadmium, iron, lead, manganese, zinc, copper and sulfate. The pollution generated by abandoned mining activities in the area of Butte, Montana has resulted in the designation of the Silver Bow Creek-Butte Area as the largest Superfund (National Priorities List) site in the U.S. This paper reports the results of bench-scale studies conducted to develop a resource recovery based remediation process for the clean up of the Berkeley Pit. The process utilizes selective, sequential precipitation (SSP) of metals as hydroxides and sulfides, such as copper, zinc, aluminum, iron and manganese, from the Berkeley Pit AMD for their removal from the water in a form suitable for additional processing into marketable precipitates and pigments. The metal biorecovery and recycle process is based on complete separation of the biological sulfate reduction step and the metal precipitation step. Hydrogen sulfide produced in the SRB bioreactor systems is used in the precipitation step to form insoluble metal sulfides. The average metal recoveries using the SSP process were as follows: aluminum (as hydroxide) 99.8%, cadmium (as sulfide) 99.7%, cobalt (as sulfide) 99.1% copper (as sulfide) 99.8%, ferrous iron (sulfide) 97.1%, manganese (as sulfide) 87.4%, nickel (as sulfide) 47.8%, and zinc (as sulfide) 100%. The average precipitate purity for metals, copper sulfide, ferric hydroxide, zinc sulfide, aluminum hydroxide and manganese sulfide were: 92.4, 81.5, 97.8, 95.6, 92.1 and 75.0%, respectively. The final produced water contained only calcium and magnesium and both sulfate and sulfide concentrations were below usable water limits. Water quality of this agriculturally usable water met the EPA's gold standard criterion.

AN - 71433204; 14641897 AB - Risk assessments include assumptions about sensitive subpopulations, such as the fraction of the general population that is sensitive and the extent that biochemical or physiological attributes influence sensitivity. Uncertainty factors (UF) account for both pharmacokinetic (PK) and pharmacodynamic (PD) components, allowing the inclusion of risk-relevant information to replace default assumptions about PK and PD variance (uncertainty). Large numbers of human organ donor samples and recent advances in methods to extrapolate in vitro enzyme expression and activity data to the intact human enable the investigation of the impact of PK variability on human susceptibility. The hepatotoxicity of trichloroethylene (TCE) is mediated by acid metabolites formed by cytochrome P450 2E1 (CYP2E1) oxidation, and differences in the CYP2E1 expression are hypothesized to affect susceptibility to TCE's liver injury. This study was designed specifically to examine the contribution of statistically quantified variance in enzyme content and activity on the risk of hepatotoxic injury among adult humans. We combined data sets describing (1) the microsomal protein content of human liver, (2) the CYP2E1 content of human liver microsomal protein, and (3) the in vitro Vmax for TCE oxidation by humans. The 5th and 95th percentiles of the resulting distribution (TCE oxidized per minute per gram liver) differed by approximately sixfold. These values were converted to mg TCE oxidized/h/kg body mass and incorporated in a human PBPK model. Simulations of 8-hour inhalation exposure to 50 ppm and oral exposure to 5 micro g TCE/L in 2 L drinking water showed that the amount of TCE oxidized in the liver differs by 2% or less under extreme values of CYP2E1 expression and activity (here, selected as the 5th and 95th percentiles of the resulting distribution). This indicates that differences in enzyme expression and TCE oxidation among the central 90% of the adult human population account for approximately 2% of the difference in production of the risk-relevant PK outcome for TCE-mediated liver injury.

AN - 71424928; 14514952 AB - Each year, 75 million pounds of the broadleaf herbicide atrazine (ATR) are applied to crops in the United States. Despite limited solubility, ATR is common in ground and surface water, making it of regulatory concern. ATR suppresses the immunomodulatory hormones prolactin (PRL) and the thyroid hormones (THs), with developmental exposure to ATR permanently disrupting PRL regulation. We hypothesized that ATR may cause developmental immunotoxicity through its disruption of PRL or THs. To test this hypothesis, pregnant Sprague-Dawley (SD) rats were exposed to 35-mg ATR/kg/d from gestational day (GD) 10 through postnatal day (PND) 23. Separate groups were exposed to bromocryptine (BCR) at 0.2 mg/kg/2x/day to induce hypoprolactinemia or to propylthiouracil (PTU) at 2 mg/kg/day to induce hypothyroidism. After the offspring reached immunologic maturity (at least 7 weeks old), the following immune functions were evaluated: natural killer (NK) cell function; delayed-type hypersensitivity (DTH) responses; phagocytic activity of peritoneal macrophages; and antibody response to sheep erythrocytes (SRBC). ATR decreased the primary antibody and DTH responses in male offspring only. Neither PTU nor BCR caused immunosuppression in any measured variable, although PTU increased phagocytosis by peritoneal macrophages. These results demonstrate that developmental exposure to ATR produced gender-specific changes in immune function in adult rats and suggest that immune changes associated with ATR are not mediated through the suppression of PRL or THs.

AN - 71417738; 14648359 AB - Descriptions of changes in hematological indices have contested the premise that the biological effects of suspended particulate matter (PM) are restricted to the lung. Employing approximately 40 hematologic parameters reflecting blood cells, chemistries, mediators, and coagulation factors, we tested the hypothesis that exposure to concentrated ambient air particles (CAPs) can be associated with changes in hematologic indices in normal humans. Twenty healthy young volunteers were exposed to either filtered air (n = 5) or CAPs (n = 15) with a mean PM mass of 120.5 +/- 14.0 microg/m3 and a range from 15.0-357.6 microg/m3. Hematologic indices were measured. Changes in all parameters are expressed as the absolute value either immediately after or 24 h after exposure. Differences between responses of those individuals exposed to filtered air and CAPs were tested using the T-test of independent means. If significant differences between the two groups were suggested by the T-test (p < .10), the relationship was further evaluated employing linear regression techniques. Regression analysis verified significant linear relationships between particle mass the individual was exposed to and (1) decrements in WBC count 24 h later, (2) decreases in lactate dehydrogenase (LDH) concentration 24 h later, and (3) elevations in fibrinogen levels 24 h later. There were no changes in either inflammatory mediators in the blood or indices of coagulation/fibrinolysis other than fibrinogen. We conclude that exposure of healthy volunteers to CAPs can be associated with decreases of both white blood cell (WBC) count and LDH and increased concentrations of fibrinogen in the blood.

AN - 71351868; 14607401 AB - U.S. EPA Methods 1622 and 1623 are used to detect and quantify Cryptosporidium oocysts in water. The protocol consists of filtration, immunomagnetic separation (IMS), staining with a fluorescent antibody, and microscopic analysis. Microscopic analysis includes detection by fluorescent antibody and confirmation by the demonstration of 1-4 sporozoites or nuclei after staining with 4',6-diamidino-2-phenyl indole dihydrochloride (DAPI). The purpose of this study was to evaluate a new IMS dissociation, a 10-min incubation at 80 degrees C. Heat dissociation improved the average oocyst recovery from 41% to 71% in seeded reagent water, and from 10% to 51% in seeded river samples. The average DAPI confirmation rate improved from 49% to 93% in reagent water, and from 48% to 73% in river samples. This modification improved both oocyst recovery and confirmation.

The amphibole-rich rock is the suspected cause of an abnormally high number of asbestos-related diseases reported in the residents of Libby, and in former mine and mill workers. The amphibole-rich samples were analyzed to determine composition and morphology of both fibrous and non-fibrous amphiboles. Sampling was carried out across the accessible portions of the deposit to obtain as complete a representation of the distribution of amphibole types as possible. The range of amphibole compositions, determined from electron probe microanalysis and X-ray diffraction analysis, indicates the presence of winchite, richterite, tremolite, and magnesioriebeckite. The amphiboles from Vermiculite Mountain show nearly complete solid solution between these end-member compositions. Magnesio-arfvedsonite and edenite may also be present in low abundance. An evaluation of the textural characteristics of the amphiboles shows the material to include a complete range of morphologies from prismatic crystals to asbestiform fibers. The morphology of the majority of the material is intermediate between these two varieties. All of the amphiboles, with the possible exception of magnesioriebeckite, can occur in fibrous or asbestiform habit. The Vermiculite Mountain amphiboles, even when originally present as massive material, can produce abundant, extremely fine fibers by gentle abrasion or crushing.

Methods for efficient, systematic reserve selection have generally been designed to maximize the protection of biodiversity while minimizing the costs of reserves. These techniques have not directly addressed the factors threatening species at specific sites. By incorporating measures of site vulnerability into reserve selection procedures, conservation planners can prioritize sites based on both representing biodiversity and the immediacy of factors threatening it. Here we develop two complementary approaches for identifying areas for conservation based on species composition and potential threats facing the species. These approaches build on two established methods of systematic reserve selection. The first approach involves mapping irreplaceability (a statistic derived from reserve selection theory that measures the potential importance of a site for protecting all species) and the degree to which the area is vulnerable to threats from three basic anthropogenic factors (the percentages of a site devoted to agriculture, to urban and suburban development, and to open mines). We classified areas with respect to both irreplaceability and the three indicators of vulnerability, producing a continuous ranking of all sites based on these factors. Our second approach was to incorporate site vulnerability into a reserve selection algorithm. This approach allowed us to locate those sets of sites that protected all species and were most likely to be threatened by human activities. These two analyses can provide regional-scale guidance for conservation in the Mid-Atlantic region of the United States, and they demonstrate two potential tools for solving complex conservation-planning problems.

Bioassessments reveal impairments but do not identify causes of impairments, a necessary step in the restoration of aquatic life. Furthermore, changes in biological condition are often caused by multiple stressors (chemical, physical, biological). To address this need, the USEPA has developed guidance to identify probable causes of biological impairments in aquatic ecosystems and to provide a structure for organizing the scientific evidence to make a credible case. The concepts and organizational structure of the process have potential applications to most ecoepi-demiological investigations.

As predicted by equilibrium thermodynamics, at near-neutral pH the experimental solutions were undersaturated with respect to orpiment (As sub(2)S sub(3)). However, upon acidification to pH 2 with HCl or HNO sub(3), instantaneous precipitation of poorly crystalline As sub(2)S sub(3) occurred in sulfidic solutions which resulted in the loss of dissolved arsenite. These results have implications concerning the practice of acidifying water samples containing hydrogen sulfide with HCl or HNO sub(3) for the purpose of preserving total arsenic values. If a near-neutral water sample contains 1 ppm arsenite and as little as 0.4 ppm sulfide, loss of dissolved arsenic will occur upon acidification. An alternative three-step preservation method involving base addition, oxidation, and acidification is proposed and investigated as an appropriate technique for preserving sulfide-bearing aqueous samples for total arsenic.

Despite this, prominent stream monitoring protocols focus on canopy closure (obstruction of the sky as a whole) rather than on measures of solar exposure or shading. We identify a candidate set of solar exposure metrics that can be derived from hemispheric images. These metrics enable a more mechanistic evaluation of solar exposure than can be achieved with canopy closure metrics. Data collected from 31 stream reaches in eastern Oregon enable us to quantify and compare metrics of solar exposure from hemispheric images and a metric of canopy closure with a concave densiometer. Repeatability of hemispheric metrics is generally as good as or better than the densiometer closure metric, and variation in the analysis of hemispheric images attributable to differences between analysts is negligibly small. Metrics from the hemispheric images and the densiometer are typically strongly correlated, at the scale of an individual observation and for 150 m stream reaches, but not always in a linear fashion. We quantify the character of the uncertainty in the relationship between the densiometer and the hemispheric metrics. Hemispheric imagery produces repeatable metrics representing an important ecological attribute; thus those researching the effects of solar exposure on stream ecosystems should consider the use of hemispheric imagery.

We found that subpopulations at many sites turn over frequently, with breeding choruses absent or undetectable in most years. Frequencies of detection across sites were significantly associated with the density of wetland patches (all species) and the areal extent of several terrestrial land cover categories (seven species) within 1 km. Intraspecific population fluctuations were statistically synchronized between survey sites separated by up to 50-100 km, but synchrony was not strong. Anuran abundances were significantly correlated with rainfall 1-4 years earlier, indicating that rainfall influences population fluctuations. However, population synchrony was much weaker than rainfall synchrony. Managers attempting to maintain amphibian populations regionally should focus on maintaining landscapes with high densities of wetlands and sufficient upland habitat resources. The dynamic nature of amphibian populations at individual wetlands is well known, and our results suggest that species distributions at the landscape level are similarly dynamic.

Larval Tallaperla spp. (Plecoptera:Peltoperlidae) were chosen as representative shredders and non-Tanypodinae Chironomidae (Diptera) were selected as representative collector-gatherers. Larval growth rates were measured in the treatment stream and in 2 undisturbed reference streams using in situ growth chambers. Estimates of daily growth rates were derived from change in mean length of larvae over incubation periods. Initial larval length was a significant predictor of growth in each stream for both taxonomic groups (r super(2) = 0.43-0.72, p < 0.05). Comparison of significant regression lines showed that size-specific growth of both Tallaperla spp. and chironomids was significantly reduced in the litter exclusion stream (ANCOVA, p < 0.05). Lower chironomid growth rates in the treatment stream than in the control streams indicate that production estimates based on the instantaneous growth method are actually lower than previously reported for the site. Mortality of Tallaperla spp. was also significantly higher in the treatment stream than in control streams (ANOVA, p < 0.05). Reduced growth of these representative taxa apparently results from reduced quantity of organic matter food resources. These results show that reduced growth is partially responsible for observed declines in detritivore production in the litter-exclusion stream. Riparian vegetation is often removed by urban development, logging, and agricultural activities. Failure to maintain appropriate riparian vegetation alters the connectivity between streams and the surrounding landscape and results in loss of the detrital subsidy. Several studies have now demonstrated the importance of detritus for stream ecosystem productivity (Hynes 1963, Fisher and Likens 1973, Wallace et al. 1997, 1999). Our results support those findings, and show that reduced growth of insect detritivores is yet another consequence of severing the terrestrial-aquatic linkage.

An arena ripe for application of such analysis is the deployment of transgenic crops. The new transgenic pesticidal or plant-incorporated protectant (PIP) crops have seen widespread application in the United States based on the features of higher yield, lower applications of insecticides, and control of mycotoxin content. However, open rejection of these new crops in Europe and in other countries has been a surprising message and has limited their worldwide acceptance. The US Environmental Protection Agency's (USEPA) Office of Pesticide Programs (OPP) has worked on the development and analysis of insect resistance management (IRM) strategies and has mandated specific IRM requirements for Bacillus thuringiensis (Bt) crops since 1995 under the Food, Fungicide, Insecticide, and Rodenticide Act. Improvement of data quality and sustainability of IRM strategies have been targeted in an ongoing partnership between the USEPA Office of Research and Development and the Office of Pesticide Programs that will further enhance the agency's ability to develop sustainable insect resistance management strategies for transgenic field corn (Bt corn) producing B. thuringiensis (Bt) insecticidal proteins.

Previous work has demonstrated a reduced capacity to support long-term potentiation (LTP) in animals exposed to a PCB mixture, Aroclor 1254 (A1254) via the dam in utero and throughout the preweaning period [Brain Res. 850; 1999:87-95; Toxicol. Sci. 57; 2000:102-11]. Assessment of normalized input/output (I/O) functions collected prior to LTP induction failed to reveal consistent differences in baseline synaptic transmission between control and PCB-exposed groups. The present study was designed to systematically evaluate excitatory and inhibitory synaptic transmission using a more extensive I/O analysis and paired pulse functions to assess short-term plasticity. Pregnant Long-Evans rats were administered either corn oil (control) or 6 mg/kg per day of A1254 by gavage from gestational day (GD) 6 until pups were weaned on postnatal day (PND) 21. In adult male offspring (5-11 months of age), field potentials evoked by perforant path stimulation were recorded in the dentate gyrus under urethane anesthesia. Detailed I/O functions were assessed by averaging the responses evoked in the dentate gyrus to stimulus pulses delivered to the perforant path in an extensive ascending intensity series. Population spike (PS) and postsynaptic potential (PSP) amplitudes recorded in the dentate gyrus were significantly enhanced in PCB-exposed animals relative to controls at midrange intensities. No group differences were observed in EPSP slope amplitudes. Short-term plasticity was assessed by delivering pairs of stimulus pulses at interpulse intervals (IPIs) ranging from 10 to 70 ms. In the dentate gyrus this range of intervals activates both inhibitory and excitatory mechanisms leading to a pattern of depression at brief intervals (<30 ms) followed by facilitation as the interval between pulses is extended. Paired pulse depression was decreased at an intermediate IPI (30 ms) with submaximal stimulus intensities. These data augment previous work demonstrating persistent changes in hippocampal plasticity as a result of exposure to PCBs during development. Furthermore, as increases in field potential amplitudes were observed, these findings support previous conclusions that A1254-induced LTP deficits are not readily attributable to reductions in synaptic excitability. Thus, in addition to impairment in use-dependent synaptic plasticity reported previously, the present report reveals that basic components of information processing within the hippocampus are permanently altered as a result of perinatal exposure to PCBs.

Our goal was to establish an in vivo murine model for hazard identification of LMW chemicals that have the potential to induce respiratory hypersensitivity (RH). We used a dermal sensitization protocol followed by a respiratory challenge with the evaluation of endpoints typically associated with RH in human disease. Trimellitic anhydride (TMA) was used as a prototype respiratory sensitizer and was compared to the dermal sensitizer; 2, 4-dinitrofluorobenzene (DNFB), along with vehicle controls. BALB/c mice were dermally sensitized using two exposure protocols. Mice in both protocols were dermally exposed on experimental days; D-18 and D-17 (abdomen), and D-13 (ear). On D 0 mice received an intratracheal (IT) challenge. The mice in Protocol 2 were abdominally exposed twice with the addition of exposures on D-25 and D-24. Results indicate that mice required the additional dermal sensitization and the IT challenge (Protocol 2) to significantly elevate total IgE in serum and bronchoalveolar lavage fluid (BALF). Additional responses suggestive of RH were seen following Protocol 2, including increases in BALF cell numbers and neutrophils post IT with TMA (but not DNFB). These data suggest that the dermal sensitization and IT challenge followed by evaluation of serum antibodies and lung parameters are a reasonable and logistically feasible approach towards the development of a model for RH responses to LMW chemicals.

Despite such reports from several populations, only one statistical analysis of loggerhead shrike territory distribution has been published to date. I use a spatio-temporal simulation technique to test for deviations from randomness in the spatial distribution of point data that takes into account date of nest establishment. I apply this model to data on the distribution of shrike nests in Comanche County, Oklahoma, USA, collected over the 1998 and 1999 breeding seasons. When the data are considered without regard to date of nest-establishment, the results are equivocal; nests are significantly aggregated in 1999, but not 1998. However, when order of nest establishment is taken into account, later nests are significantly more likely to be closer than expected to conspecifics in both years. This is true even when the distribution of simple resources, such as suitable nest-trees, is included in the model. These results are consistent with the hypothesis that loggerhead shrikes 'prospect' for suitable habitat using the distribution of breeding conspecifics. This aspect of loggerhead shrike breeding ecology should be considered for both habitat conservation and captive breeding and reintroduction programs for this species.

A striking example of plant species importance is the influence of N sub(2)-fixing red alder (Alnus rubra) on nutrient cycling in the forests of the Pacific Northwest. To understand the influence of red alder on watershed nutrient export, we studied the chemistry of 26 small watershed streams within the Salmon River basin of the Oregon Coast Range. Nitrate and dissolved organic nitrogen (DON) concentrations were positively related to broadleaf cover (dominated by red alder: 94% of basal area), particularly when near-coastal sites were excluded (r super(2) = 0.65 and 0.68 for nitrate-N and DON, respectively). Nitrate and DON concentrations were more strongly related to broadleaf cover within entire watersheds than broadleaf cover within the riparian area alone, which indicates that leaching from upland alder stands plays an important role in watershed nitrogen (N) export. Nitrate dominated over DON in hydrologic export (92% of total dissolved N), and nitrate and DON concentrations were strongly correlated. Annual N export was highly variable among watersheds (2.4-30.8 kg N ha super(-1) y super(-1)), described by a multiple linear regression combining broadleaf and mixed broadleaf-conifer cover (r super(2) = 0.74). Base cation concentrations were positively related to nitrate concentrations, which suggests that nitrate leaching increases cation losses. Our findings provide evidence for strong control of ecosystem function by a single plant species, where leaching from N saturated red alder stands is a major control on N export from these coastal watersheds.

Such relationships, however, are thought to be rare in wetland plant roots, although several recent studies suggest that arbuscular mycorrhizae may be important in wetland ecosystems. Our objectives were to determine (1) the level of arbuscular mycorrhizal colonization of plant roots in three freshwater marshes and (2) the effect of restoration status, hydrologic zone, and plant species identity on mycorrhizal colonization. We quantified the percentage of plant roots colonized by mycorrhizal fungi in one reference and two restored freshwater marshes in northern Indiana, USA during summer 1999. Roots were collected from soil cores taken around dominant plant species present in each of three hydrologic zones and then stained for microscopic examination of mycorrhizal colonization. Mycorrhizae were present in each wetland, in all hydrologic zones and in all sampled plants, including Carex and Scirpus species previously thought to be non-mycorrhizal. Both restored and reference wetlands had moderate levels of mycorrhizal colonization, but no clear trends in colonization were seen with hydrologic zone, which has been hypothesized to regulate the formation of mycorrhizae in wetlands. Mycorrhizal colonization levels in the roots of individual species ranged from 3 to 90% and were particularly large in members of the Poaceae (grass) family. Our results suggest that arbuscular mycorrhizae may be widely distributed across plant species and hydrologic zones in both restored and reference freshwater marshes. Thus, future research should examine the functional role of mycorrhizal fungi in freshwater wetlands.

Using 1-km advanced very high resolution radiometer (AVHRR) satellite-based land cover, we present a method to separate forest fragmentation into natural and anthropogenic components, and report results for all inhabited continents summarized by World Wildlife Fund biomes. Globally, over half of the temperate broadleaf and mixed forest biome and nearly one quarter of the tropical rainforest biome have been fragmented or removed by humans, as opposed to only 4% of the boreal forest. Overall, Europe had the most human-caused fragmentation and South America the least. This method may allow for improved risk assessments and better targeting for protection and remediation by identifying areas with high amounts of human-caused fragmentation.

The availability and appropriate use of biomarkers to determine absorbed doses of environmental chemicals such as OPs are critical issues. Biomarkers of OP exposure are typically measured in blood and urine; however, postpartum meconium has been shown to be a promising matrix for assessing cumulative in utero exposure to the fetus, and studies are currently in progress to determine the utility of using saliva and amniotic fluid as matrices. In this article, we discuss the advantages and disadvantages of the currently available OP exposure monitoring methods (cholinesterase inhibition in blood, pesticides in blood, metabolites in urine and alternative matrices); study design issues for a large, long-term study of children's environmental health; and current research and future research needs. Because OPs are rapidly metabolized and excreted, the utility of one-time spot measurements of OP biomarkers is questionable unless background exposure levels are relatively stable over time or a specific time frame of interest for the study is identified and samples are collected accordingly. Biomarkers of OP exposure can be a valuable tool in epidemiology of children's environmental health, as long as they are applied and interpreted appropriately.

Some practitioners have advocated an ecological approach (i.e., "top down") to wildlife assessments to account directly for the uncertainties inherent in aggregating direct toxicological effects to individuals when estimating population risk (i.e., "bottom up" techniques). This paper suggests a methodology for conducting wildlife risk assessments that incorporates both the "bottom up" and "top down" techniques by taking into account multiple lines of evidence that are gathered by proceeding through a tiered approach including: 1) concentration of chemicals in relation to levels reported to be harmful; 2) bioassays or toxicity studies to define dose-response relationships; and 3) field studies of population or community responses. A step-wise process progressing through these three tiers is a cost-effective method for developing the necessary information. This method is analogous to standard epidemiological approaches. Incorporation of continued monitoring and directed field studies into risk management is suggested as a means to move forward with environmental management decisions in the face of the significant uncertainties that will continue to be associated with wildlife risk assessments.

As these developments continue, it is reasonable that some of these chemistries or technologies have the potential to be implemented on the plant scale. With this in mind, a new green technology will most certainly have a potential impact on the sustainability of a process. It should also be noted that although a "green" technology may appear environmentally friendly, there currently is no all-inclusive methodology for assessing the actual sustainability of the chemical reaction or process. In order to assess a process, a set of sustainability indicators, or metrics, are required. Research within the U.S. Environmental Protection Agency (USEPA) has laid the foundation for an indicator model, GREENSCOPE (Gauging Reaction Effectiveness for the ENvironmental Sustainability of Chemistries with a multi-Objective Process Evaluator), that evaluates a particular reaction or process for sustainability in the following areas: Environment, Energy, Efficiency, and Economics. These four Es provide a quantitative definition of process sustainability, and allow for a direct comparison between two similar processes with differing reaction chemistries or process technologies. These aspects of sustainable chemical research will also be of importance as bench processes are scaled up to sustainable industrial processes.

Should this rate of use be maintained, two dire consequences will follow: first, the future generations will be unable to maintain a high standard of living, and second, developing countries will have less of an opportunity to bring their living standards to a level comparable to that of the affluent West. The practice of chemical engineering, perhaps more than any other technical discipline, involves the use of natural material and energy resources for the production of value-added articles and services of commerce. It is critically important that chemists and chemical engineers incorporate the ideas of sustainability into process and product design, manufacturing, and value chain management for the purpose of minimizing resource utilization and adverse environmental impact. This paper deals with the ideas of sustainability, and what chemists and chemical engineers can do to prevent the consequences of unsustainable resource utilization.

Consumption leads to different kinds of environmental impacts from all parts of a product's life cycle: raw material extraction, production, use, recovery, and final disposal, including transportation throughout the cycle. Working with products embraces many different environmental problems, instruments and mechanisms, stakeholders, various policy areas, etc. The current structure of industry and the considerable amount of international trade requires a strategy that takes these conditions into account in advancing sustainable production and consumption. The European Union has developed an Integrated Product Policy, built on life cycle thinking, in order to reduce resource use. The Swedish Environmental Protection Agency (SEPA) was commissioned by the Swedish Government in 2001 to develop the Integrated Product Policy (IPP). The aim of IPP is to minimize the impact of products on human health and the environment throughout their life cycles, from cradle-tograve, to improve sustainable production and consumption, and advance the government's environmental quality objectives. SEPA studied how instruments and mechanisms can work together and be made more effective, and what new instruments and mechanisms might be needed to achieve the goals laid down in IPP. This paper presents the results of the study.

A Look at Three USEPA Case Studies AN - 16171283; 5896727 AB - The movement to buy "environmentally-friendly" products was recently reinvigorated by the signing of the 2002 Farm Act that requires all federal agencies to give preference to products made, in whole or significant part, from biobased material. This paper addresses the reality behind widely held beliefs regarding "green" issues, and shows how complex it can be to choose among alternative products. Examples are presented in which the U.S. Environmental Protection Agency (USEPA) used different approaches, all based on life cycle assessment (LCA), to evaluate the environmental trade-offs of bio-based alternatives. These examples incorporate various combinations of life cycle inventory (LCI) and life cycle impact assessment (LCIA). The first example presents results of a USEPA Office of Research & Development (ORD) project called the Framework for Responsible Environmental Decision-Making (FRED). The FRED framework uses a set of impact categories in an LCIA. Motor oil, wall insulation, and asphalt coating alternatives were all studied using FRED. The second example is a pilot study in the USEPA's Environmentally Preferable Purchasing program. Using a mix of LCI and LCIA, transformer oil and hard surface cleaner alternatives were evaluated. Finally, the paper presents preliminary LCI results of another ORD effort comparing fuel additives ethanol and MTBE. These examples demonstrate that the move to bio-based products is not an across-the-board "win" for the environment. While LCAs cannot, at this time, provide a definitive answer as to the preferability of bio-based products, it is the best tool to identify environmental trade-offs, thereby providing additional information to support decision-making.

This was a 1-year investigation of PM and related co-pollutants involving participants living within the RTP area of North Carolina. Primary goals were to characterize the relationships between ambient and residential PM measures to those obtained from personal exposure monitoring and estimate ambient source contributions to personal and indoor mass concentrations. A total of 38 participants living in 37 homes were involved in personal, residential indoor, residential outdoor and ambient PM sub(2.5) exposure monitoring. Participants were 30 non-smoking hypertensive African-Americans living in a low-moderate SES neighborhood (SE Raleigh, NC) and a cohort of eight individuals having implanted cardiac defibrillators (Chapel Hill, NC). Residential and ambient monitoring of PM sub(10) and PM sub(10-2.5) (coarse by differential) was also performed. The volunteers were monitored for seven consecutive days during each of four seasons (summer 2000, fall 2000, winter 2001, spring 2001). Individual PM sub(2.5) personal exposure concentrations ranged from 4 to 218 mu g m super(-3) during the study. The highest personal exposures were determined to be the result of passive environmental tobacco exposures. Subsequently, similar to 7% of the total number of personal exposure trials were excluded to minimize this pollutant's effect upon the overall analysis. Results indicated that a pooled data set (seasons, cohorts, residences, participants) was appropriate for investigation of the basic mass concentration relationships. Daily personal PM sub(2.5) mass concentrations were typically higher than their associated residential or ambient measurements (mean PERSONAL=23.0, INDOOR=19.1, OUTDOOR=19.3, AMBIENT=19.2 mu g m super(-3)). Mean personal PM sub(2.5) exposures were observed to be only moderately correlated to ambient PM sub(2.5) concentrations (r=0.39).

One member of each pair served as a reference site and the other was affected by mild to moderate human disturbance from a point or diffuse source (fish farm effluents, small municipal sewage discharges, a dam, agriculture and grazing). Samples were taken from riffles, stream edges and rocks in pools, mostly using hand nets (RBA) and Hess samplers (quantitative). Macroinvertebrates in RBA samples were always subsampled by live-picking by eye on site for 30 min. Comparisons were made between novice operators (university undergraduates) and experienced river biologists in the application of RBA, including sample identification. Quantitative samples were collected only by experienced river biologists, preserved and picked under stereomicroscopes in the laboratory, either in their entirety or after mechanical subsampling. Specimens were identified to family level for both methods. Novices recorded slightly fewer families than experts and misidentified some specimens, and expert data for the same site and habitat were on average more consistent than novice data. Nevertheless, Procrustes analysis of ordinations showed that differences between RBA and quantitative data did not depend on the type of RBA operator. And regardless of the operator, RBA data were better than quantitative data at discriminating between reference and disturbed sites for all three habitat types. We conclude that this type of RBA is sensitive and cost-effective, and we recommend improvements to inter-operator consistency.

Following the application, measurements were made in the kitchen, den and master bedroom over 21 days. Airborne concentrations were collected using both polyurethane foam (PUF) and the OSHA versatile sampler composed of XAD and PUF media located in tandem. Measured airborne concentrations were similar for the two samplers and were higher in the three rooms following the application. The highest measured concentrations were reached during the initial 24-h following application; concentrations subsequently declined over the 21-day study period to levels slightly above background. Spatial and temporal distributions onto surfaces were measured using 10-cm super(2) rayon deposition coupons located on the floor. Sections were cut from existing carpet to determine the total extractable residues. Chlorpyrifos was measured from all matrixes in the kitchen, den and bedroom and the data shows the transport of airborne residues from the point of application to remote locations in the house. The findings are compared and discussed relative to another study conducted in which total release aerosols containing chlorpyrifos were activated in the IAQ research house and the resulting distributions evaluated. For both studies dose estimates were constructed for the exposure pathways using the Stochastic Human Exposure and Dose Estimation Model for pesticides. The United States Environmental Protection Agency has been mandated to examine children's exposure to environmental pollutants such as pesticides.

AN - 71432001; 14655712 AB - As part of the EPA's mission to protect the environment, chemicals of concern (CoCs) at Superfund or other hazardous waste sites are cleaned up based on their potential toxicity to humans and the surrounding ecosystem. Oftentimes, there is a lack of experimental toxicity data to assess the health effects for a CoC in the literature. This research describes a method using Quantitative Structure Toxicity Relationships (QSTRs) for identifying a surrogate chemical for any given CoC. The toxicity data of the surrogate chemical can then be used to rank hazardous waste-site chemicals prior to cleanup decisions. A commercial QSTR model, TOPKAT, was used to establish structural and descriptor similarity between the CoC and the compounds in the QSTR model database using the Oral Rat Chronic LOAEL model. All database chemicals within a similarity distance of < or = 0.200 from the CoC are considered as potential surrogates. If the CoC fails to satisfy model considerations for the LOAEL model, no surrogate is suggested. Potential surrogates that have toxicity data on Integrated Risk Information System (IRIS), Health Effects Assessment Summary Tables (HEAST), or National Center for Environmental Assessment (NCEA) provisional toxicity value list become candidate surrogates. If more than one candidate surrogate is identified, the chemical with the most conservative RfD is suggested as the surrogate. The procedure was applied to determine an appropriate surrogate for dichlorobenzophenone (DCBP), a metabolite of chlorobenzilate, dichlorodiphenyltrichloroethane, and dicofol. Forty-seven potential surrogates were identified that were within the similarity distance of < or = 0.200, of which only five chemicals had an RfD on IRIS, HEAST, or on the NCEA provisional toxicity value list. Among the five potential surrogates, chlorobenzilate with an RfD of 2 x 10(-2) mg/kg-day was chosen as a surrogate for DCBP as it had the most conservative toxicity value. This compared well with surrogate selection using available metabolic information for DCBP and its metabolites or parent compounds in the literature and the provisional toxicity value of 3 x 10(-2) mg/kg-day that NCEA developed using a subchronic study.

AN - 75715894; 14511724 AB - The main objective of this paper is to use Bayesian methods to estimate the kinetic parameters for the inactivation kinetics of Cryptosporidium parvum oocysts with chlorine dioxide or ozone which are characterized by the delayed Chick-Watson model, i.e., a lag phase or shoulder followed by pseudo-first-order rate of inactivation. As the length of the lag phase (CT(lag)) is not known, Bayesian statistics provides a more accurate approach than traditional statistical methods to fitting the delayed Chick-Watson kinetics. Markov Chain Monte Carlo method is used to estimate CT(lag) and first-order rate constant values. This method is also used to estimate the minimum CT requirement (with safety factor) for 99% inactivation of C. parvum oocysts.

These have received some attention in the mathematical literature, but very little has appeared on their applications to chemical graphs. The present study focuses on these and also generalizes the acyclic or matching polynomial to an equally large class of acyclic immanantal polynomials, generalizes the Sachs theorem to immanantal polynomials, and sets forth relationships between the immanants and other graph properties, namely, Kekulé structure count, number of Hamiltonian cycles, Clar covering polynomial, and Hosoya sextet polynomial.

AN - 71353911; 14620836 AB - The Solvent Extraction Residual Biotreatment (SERB) technology was evaluated at a former dry cleaner site in Jacksonville, FL, where an area of tetrachloroethylene (PCE) contamination was identified. The SERB technology is a treatmenttrain approach for complete site restoration, which combines an active in situ dense nonaqueous-phase liquid (DNAPL) removal technology, cosolvent extraction, with a passive enhanced in situ bioremediation technology, reductive dechlorination. During the in situ cosolvent extraction test, approximately 34 kL of 95% ethanol/5% water (v:v) was flushed through the contaminated zone, which removed approximately 60% of the estimated PCE mass. Approximately 2.72 kL of ethanol was left in the subsurface, which provided electron donorfor enhancement of biological processes in the source zone and downgradient areas. Quarterly groundwater monitoring for over 3 yr showed decreasing concentrations of PCE in the source zone from initial values of 4-350 microM to less than 150 microM during the last sampling event. Initially there was little to no daughter product formation in the source zone, but after 3 yr, measured concentrations were 242 microM for cis-dichloroethylene (cis-DCE), 13 microM for vinyl chloride, and 0.43 microM for ethene. In conjunction with the production of dissolved methane and hydrogen and the removal of sulfate, these measurements indicate that in situ biotransformations were enhanced in areas exposed to the residual ethanol. First-order rate constants calculated from concentration data for individual wells ranged from -0.63 to -2.14 yr(-1) for PCE removal and from 0.88 to 2.39 yr(-1) for cis-DCE formation. First-order rate constants based on the change in total mass estimated from contour plots of the groundwater concentration data were 0.75 yr(-1) for cis-DCE, -0.50 yr(-1) for PCE, and -0.33 yr(-1) for ethanol. Although these attenuation rate constants include additional processes, such as sorption, dispersion, and advection, they provide an indication of the overall system dynamics. Evaluation of the groundwater data from the former dry cleaner site showed that cosolvent flushing systems can be designed and utilized to aid in the enhancement of biodegradation processes at DNAPL sites.

AN - 71353329; 14603346 AB - The transfer of pesticides from household surfaces to foods was measured to determine the degree of excess dietary exposure that occurs when children's foods contact contaminated surfaces prior to being eaten. Three household flooring surfaces (ceramic tile, hardwood, and carpet) were contaminated with an aqueous emulsion of commercially available pesticides (diazinon, heptachlor, malathion, chlorpyrifos, isofenphos, and cis- and trans-permethrin) frequently found in residential environments. A surface wipe method, as typically used in residential exposure studies, was used to measure the pesticides available on the surfaces as a basis for calculating transfer efficiency to the foods. Three foods (apple, bologna, and cheese) routinely handled by children before eating were placed on the contaminated surfaces and transfers of pesticides were measured after 10 min contact. Other contact durations (1 and 60 min) and applying additional contact force (1500 g) to the foods were evaluated for their impact on transferred pesticides. More pesticides transferred to the foods from the hard surfaces, that is, ceramic tile and hardwood flooring, than from carpet. Mean transfer efficiencies for all pesticides to the three foods ranged from 24% to 40% from ceramic tile and 15% to 29% from hardwood, as compared to mostly non-detectable transfers from carpet. Contact duration and applied force notably increased pesticide transfer. The mean transfer efficiency for the seven pesticides increased from around 1% at 1 min to 55- 83% when contact duration was increased to 60 min for the three foods contacting hardwood flooring. Mean transfer efficiency for 10-min contact increased from 15% to 70% when a 1500 g force was applied to bologna placed on hardwood flooring. Contamination of food occurs from contact with pesticide-laden surfaces, thus increasing the potential for excess dietary exposure of children.

AN - 71318781; 14587918 AB - The risk of photoactivated PAH toxicity in contaminated aquatic systems has not been well characterized. To document risk, amphipods (Gammarus spp.) were collected from two polycyclic aromatic hydrocarbon (PAH)-contaminated sites in the lower St. Louis River and Duluth Harbor, USA (Hog Island and USX) as well as a reference site (Chipmunk Cove) and were exposed in two separate, replicate tests to controlled intensities of solar radiation for 3 d. Contaminated site organisms died significantly faster compared to control site organisms. In all tests, mortality was strongly related to ultraviolet-A (UV-A; 320-400 nm) dose. Ultraviolet-B (280-320 nm) radiation did not increase mortality. To compare susceptibility among populations, regressions of arcsine-transformed, proportionate mortality versus UV dose were completed for each, and the slopes were statistically compared. Response slopes for the two contaminated site populations were both significantly greater than the reference site population (p = 0.0001 for test 1; p = 0.0002 for test 2). These results indicate that organisms residing in PAH-contaminated environments can accumulate PAH concentrations sufficient to be at risk for photoactivated toxicity. Although amphipods are not typically at risk of PAH-photoactivated toxicity because they are largely protected from exposure to sunlight, they are representative surrogates for species that may be similarly protected at some life stages (and thus able to accumulate significant PAH tissue concentrations) but not at others.

The potential exposure and associated health risks due to the contaminants are dependent upon the environmental transport mechanisms, as well as the pathways by which receptors may be exposed to the transported chemicals. For the groundwater pathway, particularly in shallow unconfined aquifers, the transport of volatile organic chemicals (VOCs) is of special interest because active migration of the contaminants could occur in the vapor phase, either volatilizing directly from the source or from the water table. The simulation of transport of contaminants in unconfined aquifers requires a solution of the variably saturated flow and transport equations which are highly non-linear, and subsequently computationally intensive. As modern risk assessment relies more and more on stochastic simulations to assist in quantifying uncertainty associated with the evaluation of contamination levels at receptor locations, it is imperative that an appropriate simulation methodology for flow and transport of VOCs, taking into account of the vapor-phase transport stochastically, be developed. This paper presents an approximate solution technique designed to minimize the computational efforts, while maintaining the accuracy of the solution. It is based on a composite technique which allows the flow and transport processes to be divided into three stages: (i) flow and transport in the vadose zone in the vicinity of the source or waste management unit, (ii) in the saturated zone, and (iii) in the vapor phase due to back volatilization at a distance away from the source or the waste management unit. The developed solution technique assumes that the waste management unit is rectangular, and that the vadose zone thickness, the saturated thickness, and material properties are uniform. Semi-analytical and numerical techniques are used to provide solutions to the three-dimensional flow and transport equations. Details of the solution procedures, verification and application examples, and substantial savings in computational efforts are discussed.

These impacts include high acidity and metals in surface and ground water, substantial precipitation of iron-bearing phases on the stream substrate, channel modification, sedimentation and habitat disruption. DMC comprises a watershed of about 5.2 square miles, of which approximately one-half is drained by Belltown Creek, a tributary to DMC that was not impacted by mine wastes and materials. DMC is the subject of continuing remedial actions by EPA Region 4. A phased approach to remediating the watershed was developed during a planning process. Initial efforts concentrated on understanding the nature of impacts and included surface water monitoring; reconnaissance sampling of wastes, soil, and sediment; a mine waste inventory; and waste testing. The inventory identified approximately 9.7 million cubic yards of mine wastes, by-product materials and contaminated soils in the affected area of about 2.5 square miles, including slag, iron calcine, sulfide concentrate, and sulfide-bearing mine rock. Most of these materials are situated on the stream banks, atop the former creek channel, or in the creek bed. In the second phase, studies of the lower creek permitted decisions to be made that will limit discharge of contaminated water from DMC to the Ocoee River. In the third phase, we examined four significant sources of acid to DMC: 1) a pile of sulfide-bearing iron calcine at the creek headwaters; 2) a small pile of sulfide-bearing waste rock; 3) a pile of mixed iron-sulfide and copper-sulfide mill concentrate; 4) a tunnel outlet and French drain that collect seepage from overlying waste materials. These sources were prioritized for remedial action based on increases in contaminant load in DMC, effects on ground water, and source volume and character. Future remedial investigations will target non-acid generating materials, mostly slag, that contribute metals to the DMC system. Once sources are controlled, restoration of the stream channel and rehabilitation of aquatic and riparian habitat can begin.

Laboratory experiments were conducted using site-derived water to assess the impact of these coupled processes on the removal of dissolved arsenic from the water column. The measured concentration of total organic carbon (TOC) from shallow and deep water sampled from the pond was approximately 15 and 200 mg C/L, respectively. Experiments conducted with these samples along with synthetic controls containing no organic carbon demonstrated that observed rates were dependent on the chemical composition of the discharging ground water. Increasing dissolved organic matter did not significantly interfere with ferrous iron oxidation, but inhibited precipitation of hydrous ferric oxide and subsequent sorption of arsenic. For experiments with 200 mg C/L TOC, there was a strong relationship between the fraction of precipitated iron and the fraction of sorbed arsenic. Laboratory- and field-derived hydrous iron oxide precipitates were characterized to evaluate mineralogy and arsenic distribution. Precipitates formed in the presence of organic carbon were consistent with formation of a 2-line ferrihydrite. These data were used to aid interpretation of field observations at the ground water-surface water interaction zone with respect to observed arsenic removal.

Hydrochemical characteristics of ground water near landfills within this zone indicate a substantial mobilization of arsenic beneath and immediately down gradient from these sites. Arsenic levels, typically less than 30 mu g/L up gradient, range from 50 to 700 mu g/L down gradient occasionally exceeding 5000 mu g/L. High arsenic concentrations correlate with iron concentrations of up to 220,000 mu g/L and manganese concentrations of up to 9,250 mu g/L. ORP ranges from 339 mV to -64 mV and pH values range between 4.88 and 6.70. Our study of 57 ground water samples from five landfill sites indicates that the source of arsenic is most likely due to a reductive dissolution of HFO coatings and release of sorbed arsenic complexes. All samples were analyzed for major and minor dissolved constituents as well as characterized by water quality parameters in the field. Chemical parameters analyzed as part of this study include alkalinity, chloride, fluoride, nitrite, nitrate, bromide, sulfate, ortho-phosphate, sodium, ammonium, potassium, magnesium, calcium, lithium, iron, manganese, arsenic, DOC, DIC, temperature, pH, ORP, conductance, dissolved oxygen, and turbidity. Our objective for this study is to evaluate the role of hydrochemical constraints, if any, on the levels of arsenic present in the down gradient ground water. The Geochemist's Workbench program is applied to model As, Fe, and Mn using the measured constituents in the liquid solutions. Eh-pH modeling of arsenic in the up gradient section of ground water points to the presence of singly and doubly dissociated pentavalent arsenic (H (sub 2) AsO (sub 4) - and HAsO (sub 4) --) whereas in the contaminated down gradient ground water the arsenic is in the form of undissociated H (sub 3) AsO (sub 3) . No arsenic bearing solids in equilibrium with ground water have been identified. However, there is an evidence for precipitation of solids containing iron and manganese. In the case of manganese the model indicates saturation with respect to rhodochrosite and for iron saturation with respect to siderite and pyrite. Arsenic variation diagrams suggest that the solid phases of Mn or Fe appear to have no effect on the dissolved arsenic.

Under these conditions synthetic fine-grained crystalline ferberite ( approximately 10-30 mu m) dissolves incongruently and is accompanied by precipitation of potassium tungstate bronze phases, K (sub x) WO (sub 3) x = 0.2-0.3). Changes in the W/Fe mol ratios in the aqueous phase were also observed. Aqueous W and Fe concentration values are a function of the total mKCl in the system and the initial mHCl. Representative molal solubility values of W and Fe range from 0.002-0.05 in 0.7 mKCl to 0.02-0.15 in mKCl. An analysis of experimental results indicate monomer tungsten species are dominant in homogeneous 0.7-3.0 mKCl solutions at 1000 bars; whereas, dimer complexes of tungsten are dominant in 4.0-8.9 mKCl and in the two-phase region at 400 and 500 bars. The relationship between solubility and pressure is yet to be defined. The data at 400 and 500 bar represent the apparent solubility values, since two conjugate fluids of different density co-exist. Estimated ferberite solubility (in wt. %) in the liquid (L) and vapor (V) phases are S (sub Ferb) (500 degrees C, 500 bar) = 0.21 (C (sub V) = 0.96 wt. %), 2.03 (C (sub L) = 34.59) and S (sub Ferb) (500 degrees C, 400 bar) = 0.5 (C (sub V ) = 0.32), 2.57 (C (sub L) = 58.25), where C (sub L ) and C (sub V) are KCl concentrations in liquid and vapor, respectively. The results suggest a large bulk solubility value (ore-bearing capacity) in the dense, salt-rich component of the two-phase fluid.

A few studies have shown horizontal flow for short periods of time, and others have demonstrated specific circumstances under which the assumption fails. But, surprisingly, this investigator could not find direct testing of the underlying concept-that under "normal" conditions (i.e., no vertical hydraulic gradient) water enters one side of a well and exits the other side of the well at roughly the same elevation. To test the horizontal flow assumption, a physical sand tank model was constructed to observe flow-through in a simulated monitoring well. The well, filter pack, and aquifer on either side of the well largely mimics real-world conditions of a submerged well in a moderately high permeability sand. Behavior of a dye "stringer" was recorded using digital time-lapse photography at real-world ground water seepage velocities. Neutrally-buoyant and different-density dye "stringers" were observed entering the well over a period of several days for each test. In all tests, regardless of flow rate or small density differences, the dye stringer eventually diluted and mixed in the monitoring well. Since the well model closely approximates a cross-section of an actual-size well subjected to real-world flow rates, mixing appears to be the rule rather than the exception for near-neutrally-buoyant contaminant stringers as they enter monitoring wells. There are several clear and important implications. 1) In-well mixing and flow-weighted concentration averaging occurs in a well before any purge or sampling efforts are made. 2) In-well mixing may mask low to moderate contaminant stratification in an aquifer. 3) Contaminant stratification, if present inside a well, implies strong contaminant stratification outside the well. 4) Contaminant stratification inside a well may not correspond to stratification at the same interval outside the well. 5) Vertical stratification within an aquifer may not be accurately monitored by sampling multiple intervals within an open well. 6) In-well barriers may limit mixing and assist in defining intervals of aquifer contaminant stratification.

Wheat and rice straw stubble collected from two western US states were tested in a field burn simulation to determine emission factors. The resulting emission factor was approximately 0.5 ng toxic equivalency (TEQ)/kg burned for both sources. When coupled with published agricultural data on crop residue burning, about 1 g TEQ/year can be expected from wheat and rice straw residue burning, making this an apparently minor source of PCDDs/Fs in the United States.

The primary purpose of this paper is to develop two mathematical models, lognormal and logarithmic, that effectively express excess lung cancer mortality as a function of asbestos concentration for an example set of data and also to suggest using these two models for additional HAPs. The secondary purpose of this paper is to calculate a "safe" asbestos concentration by first assuming a default linear extrapolation (to one excess death per million people, as specified for carcinogenic HAPs). The resulting "safe" concentration is an impossible-to-achieve 1/1000 of present background asbestos concentrations. A letter to the editor and a response in this Journal issue use additional asbestos data that suggest that the "safe" concentration should be about 730 times higher than first calculated here and that a default nonlinear extrapolation should be used instead, with the "safe" concentration proportional to the desired mortality level raised to the 0.39 power. These results suggest that the most important problem in setting a "safe" concentration for each carcinogenic HAP is to determine the correct nonlinear extrapolation to use for each HAP.

Copies were produced on a single photocopier using two toners manufactured for this copier but having different styrene contents. The resulting emission models were used to predict whether indoor styrene concentrations resulting from copied paper in a typical office might be significantly reduced by use of a low-emitting toner for a given copier. The styrene emissions were best represented by either a 3rd-order decay model or by a power law model having an exponent between 0.3 and 0.5 (R super(2) = 0.94-0.99). The two toners resulted in copied paper having significantly different styrene emissions (p < 0.01), with unit mass emissions over 1000 hr being nine times greater with the higher-emitting toner. But copied paper is predicted to produce peak indoor styrene concentrations in a typical office no more than 1% of the World Health Organization health-based guideline. Thus, for the toners considered here, indoor styrene exposures from copied paper appear to be too limited to provide incentive for switching to the lower-emitting toner. The ability to generalize these conclusions is limited by the fact that only one copier and two toners could be tested.

AN - 19189112; 5772481 AB - We investigated linkages between fishes and fluvial geomorphology in 31 wadeable streams in the Etowah River basin in northern Georgia, U.S.A. Streams were stratified into three catchment sizes of approximately 15, 50 and 100 km super(2), and fishes and geomorphology were sampled at the reach scale (i.e. 20-40 times stream width).Non-metric multidimensional scaling (NMDS) identified 85% of the among-site variation in fish assemblage structure and identified strong patterns in species composition across sites. Assemblages shifted from domination by centrarchids, and other pool species that spawn in fine sediments and have generalised food preferences, to darter-cyprinid-redhorse sucker complexes that inhabit riffles and runs, feed primarily on invertebrates, and spawn on coarser stream beds.Richness and density were correlated with basin area, a measure of stream size, but species composition was best predicted (i.e. |r| between 0.60-0.82) by reach-level geomorphic variables (stream slope, bed texture, bed mobility and tractive force) that were unrelated to stream size. Stream slope was the dominant factor controlling stream habitat. Low slope streams had smaller bed particles, more fines in riffles, lower tractive force and greater bed mobility compared with high slope streams.Our results contrast with the 'River Continuum Concept' which argues that stream assemblages vary predictably along stream size gradients. Our findings support the 'Process Domains Concept', which argues that local-scale geomorphic processes determine the stream habitat and disturbance regimes that influence stream communities.

This species complex displays continuous morphological variation across the study area, which has been previously interpreted as the product of hybridization between allopatric species. A microsatellite analysis indicates that there was little genetic structuring across the morphological cline and only low levels of population differentiation. The nested clade analysis of the J sub(LA+) region of the chloroplast DNA (cpDNA) indicates that the geographical distribution of cpDNA haplotypes is unlikely to be the result of historical hybridization events, and that restricted seed-mediated gene flow with isolation by distance is responsible for the phylogeographical distribution. A more plausible explanation for the origin and persistence of the morphological cline is that the process of continuous morphological diversification has been promoted by a directional selection gradient. This study addresses species status within Eucalyptus and the belief that hybridization is widespread and is an important process in the group's evolution.

This paper reviews 149 self-described landscape studies published between 1987 and 2001. From each paper, data for several variables were gathered that we proposed may influence the choice of scale. These variables included the taxa the research considered, the characteristics of the landscape of interest, the species response variables measured, the type of methodology employed by the study, the habitat type(s) surveyed, and the technique(s) used to create habitat maps. Our results demonstrated that only 61% of the papers identified both the grain and extent at which the research was conducted. Taxonomic group, landscape characteristics, and study type all appeared to influence both the choice of grain and extent for the study. Wide variation (standard deviation) in grain and extent among studies suggests that researchers either used some factor not considered here to select scale, or made decisions of the scale on pragmatic grounds, rather than on the appropriateness of the scale to the variables. Finally, 24 of the 149 studies reviewed researched the same combination of categories of the six variables that we considered, yet only for one combination was the grain and extent used within the same order of magnitude. This review highlights the need for more structured choice of scale in landscape studies, and in particular the need for more standardized size of grain and extent for greater comparability among studies.

A database of input parameters allowed Monte Carlo analysis with the model. The resulting kernel densities of predicted attenuation during percolation indicated very small, but finite probabilities of failure for all homogeneous USDA classified soils to attenuate reovirus 3 by 99.99% in one-half meter of gravity drainage. The logarithm of saturated hydraulic conductivity and water to air-water interface mass transfer coefficient affected virus fate and transport about 3 times more than any other parameter, including the logarithm of inactivation rate of suspended viruses.Model results suggest extreme infiltration events may play a predominant role in leaching of viruses in soils, since such events could impact hydraulic conductivity. The air-water interface also appears to play a predominating role in virus transport and fate. Although predictive modeling may provide insight into actual attenuation of viruses, hydrogeologic sensitivity assessments for the unsaturated zone should include a sampling program.

The approach is based on five basic parameters that affect bioaccumulation of nonionic organic chemicals: The distribution of chemical between sediment and water, the hydrophobicity of the compound (expressed as the n-octanol/water partition coefficient, K sub(ow)), the relationship of food chains to water and sediment, the length of the food chains, and the degree to which the chemical is metabolized. The visualization approach using water-sediment XY plots captures and visually presents the existing bioaccumulation knowledge in a form that is readily understandable from chemical, biological, and ecological aspects and, therefore, useful in the assessment, communication, and management of risk for persistent bioaccumulative toxicants.

The effect of HOCI appears at first to be contrary because HOCI rapidly oxidizes nitrite and hence should reduce NDMA formation from a mechanism involving classical nitrosation. The enhanced nitrosation by the presence of HOCI is, however, consistent with a mechanism that involves the formation of a highly reactive nitrosating intermediate such as dinitrogen tetroxide (N sub(2)O sub(4)) formed during the oxidation of nitrite to nitrate. This mechanism is quite unlike another recently proposed NDMA formation pathway involving the rate-limiting oxidation of DMA directly by monochloramine. NDMA formation by the proposed HOCI-enhanced nitrosation pathway is inhibited by the presence of ammonia and occurs very quickly, only during the short period during which nitrite oxidation occurs. The general importance of this NDMA formation mechanism in actual drinking water appears to be limited by the amount of DMA and nitrite typically present. The mechanism described here, however, suggests the potential involvement of other nitrogen redox reactions that may produce reactive intermediates leading to the indirect and incidental formation of NDMA in the presence of appropriate organic nitrogen precursor.

Surrogates for exposure have also been used, such as the ambient air quality measured at fixed monitoring sites. These approaches are based on available science. Meanwhile, during the past decade, researchers at the U.S. EPA, universities, and institutes have been developing better scientific approaches for measuring and modeling real or potential human exposures that explain hazardous exposure situations. In parallel, the President, Congress, and the public have set higher expectations for government programs, such as NAAQS. These expectations were first defined through the evolution of the "risk assessment-risk management paradigm" and then by the requirements of the Government Performance and Results Act (GPRA), which defines accountability for government programs. In this article we examine the challenges that EPA faces in its NAAQS program and how the scientific results of its National Exposure Research program, conducted by the National Exposure Research Laboratory (NERL) within EPA's Office of Research and Development, and its partners, such as the Exposure Measurement & Assessment Program at the Environmental and Occupational Health Sciences Institute (EOHSI), can be used to achieve these higher expectations. Specifically, we will show the implications that accountability brings to the risk assessment-risk management paradigm.

Rates of acid- neutralization and of metal (Cu, Cd, Ni, Zn, Hg, Al, and Mn) and metalloid (As) uptake were determined in batch systems using simulated mine drainage (initial pH 2.3-4.5; total dissolved solids 14 000-16 000 mg l super(-1)). Metal removal from solution and acid-neutralization occurred simultaneously and were most rapid during the initial 24 h of reaction. Reaction half-lives ranged from 1.50 +/- 0.09 h for Al to 8.15 +/- 0.36 h for Zn. Geochemical model results indicate that metal removal is most effective in solutions that are highly undersaturated with respect to pure-metal hydroxides suggesting that adsorption is the initial and most rapid metal uptake mechanism. Continued adsorption onto or co-precipitation with iron corrosion products are secondary metal uptake processes. Sulfate green rust was identified as the primary iron corrosion product, which is shown to be the result of elevated [SO sub(4) super(2-)]/[HCO sub(3) super(-)] ratios in solution. Reversibility studies indicate that zero-valent iron will retain metals after shifts in redox states are imposed, but that remobilization of metals may occur after the acid-neutralization capacity of the material is exhausted.

AN - 75758608; 14550852 AB - Chlorotriazines interact with undifferentiated PC12 cells in vitro to modulate catecholamine synthesis and release, but the mechanism(s) responsible for this effect had not been determined. In this study we evaluated the effect of atrazine, simazine and cyanazine on the protein expression of the enzymes responsible for the synthesis of dopamine [tyrosine hydroxylase (TH)] and norepinephrine [dopamine-beta-hydroxylase (DbetaH)]. We also examined the possible intracellular pathway associated with chlorotriazine-induced changes in catecholamine synthesis and release. Incubating PC12 cells in the presence of 100 microM atrazine and simazine decreased intracellular dopamine (DA), norepinephrine (NE) concentration and NE release, and the protein expression of TH (approximately 20%) and DbetaH (approximately 50 and 25%, respectively) after 12-24 h exposure. In contrast, cyanazine (100 microM) stimulated intracellular and released NE concentration, and the protein expression of TH (approximately 20%) and DbetaH (approximately 225%) after 12-36 h exposure. Simultaneous exposure to the essential TH co-factors (iron and tetrahydrobiopterine) was ineffective in altering cellular DA. Agents known to enhance TH and DbetaH transcription, phosphorylation or activity (e.g., 8-bromo cAMP, forskolin or dexamethasone) reversed the inhibitory effects of atrazine and simazine on the NE. Again, in contrast to atrazine and simazine, cyanazine attenuated catecholamine-depleting effect of alpha-Methyl-p-tyrosine (alphaMpT) on NE. Both DA and NE synthesis can be altered by the chlorotriazines and suggest these occur via an alteration of the synthetic enzymes TH and DbetaH.

AN - 71319427; 14584702 AB - A method was developed for the confirmed identification and quantitation of 17beta-estradiol, estrone, 17alpha-ethynylestradiol and 16alpha-hydroxy-17beta-estradiol (estriol) in ground water and swine lagoon samples. Centrifuged and filtered samples were extracted using solid-phase extraction (SPE), and extracts were derivatized using pentafluorobenzy] bromide (PFBBR) and N-trimethylsilylimidazole (TMSI). Analysis was done using negative ion chemical ionization (NICI) gas chromatography-mass spectrometry-mass spectrometry (GC-MS-MS). Deuterated analogs of each of the estrogens were used as isotope dilution standards (IDS) and were added to the samples before extraction. A limit of quantitation of 1 ng/l in ground water was obtained using 500 ml of ground water sample, 1.0 ml of extract volume and the lowest calibration standard of 0.5 pg/microl. For a 25 ml swine lagoon sample, the limit of quantitation was 40 ng/l. The average recovery of the four estrogens spiked into 500 ml of distilled water and ground water samples (n = 16) at 2 ng/l was 103% (S.D. 14%). For 25 ml of swine lagoon samples spiked at 500, 1000 and 10,000 ng/l, the average recovery for the four estrogens was 103% (S.D. 15%). The method detection limits (MDLs) of the four estrogens spiked at 2 ng/l in a 500 ml of ground water sample ranged from 0.2 to 0.6 ng/l. In swine lagoon samples from three different types of swine operations, estrone was found at levels up to 25,000 ng/l, followed by estriol and estradiol up to levels at 10,000 and 3000 ng/l, respectively. It was found that pretreatment of swine lagoon samples with formaldehyde was necessary to prevent conversion of estradiol to estrone. JF - Journal of chromatography.

Paper No. TAM-A.10 N1 - Last updated - 2010-05-03 ER - TY - JOUR T1 - Evaluation of Two Methods for Prediction of Bioaccumulation Factors AN - 19814692; 5820992 AB - Two methods for deriving bioaccumulation factors (BAFs) used by the U.S. Environmental Protection Agency in development of water quality criteria were evaluated using polychlorinated biphenyl (PCB) data from the Hudson River and Green Bay ecosystems. One method predicts BAF super(f) sub(L) super(d) values (BAFs based upon concentrations of freely dissolved chemical in ambient water and in the lipid fraction of tissue) using field-measured biota-sediment accumulation factors (BSAFs): greater than 90% of the predicted BAF super(f) sub(L) super(d) values were within a factor of 5 of their measured values for both ecosystems. The second method predicts BAF super(f) sub(L) super(d) values as the chemical's 1-octanol/water partition coefficient (K sub(ow)) times a food chain multiplier: greater than 90% of the predicted BAF super(f) sub(L) super(d) values were within a factor of 5 of their measured values for the Green Bay ecosystem and for three of the six sampling locations on the Hudson River. Poorer predictive ability with the K sub(ow) method for the other three sampling locations was believed to be due to the existence of environmental conditions not representative of the longer term ecosystem conditions assumed for the method. BAF super(f) sub(L) super(d) and BAF super(t) sub(T) values (BAFs based upon concentrations of total chemical in ambient water and in wet tissue) were compared. The within ecosystem and across ecosystems comparisons demonstrated a 2-5-fold decrease in variability (expressed as ratios of coefficients of variation, percentile ranges, and confidence ranges) for predicted BAF super(f) sub(L) super(d) values in comparison to BAF super(t) sub(T) values.

AN - 75721713; 14519490 AB - Reductions in thyroid hormone during critical periods of brain development can have devastating effects on neurological function that are permanent. Neurochemical, molecular and structural alterations in a variety of brain regions have been well documented, but little information is available on the consequences of developmental hypothyroidism on synaptic function. Developing rats were exposed to the thyrotoxicant, propylthiouracil (PTU: 0 or 15 ppm), through the drinking water of pregnant dams beginning on GD18 and extending throughout the lactational period. Male offspring were allowed to mature after termination of PTU exposure at weaning on PND21 and electrophyiological assessments of field potentials in the dentate gyrus were conducted under urethane anesthesia between 2 and 5 months of age. PTU dramatically reduced thyroid hormones on PND21 and produced deficits in body weight that persisted to adulthood. Synaptic transmission was impaired as evidenced by reductions in excitatory postsynaptic potential (EPSP) slope and population spike (PS) amplitudes at a range of stimulus intensities. Long-term potentiation of the EPSP slope was impaired at both modest and strong intensity trains, whereas a paradoxical increase in PS amplitude was observed in PTU-treated animals in response to high intensity trains. These data are the first to describe functional impairments in synaptic transmission and plasticity in situ as a result of PTU treatment and suggest that perturbations in synaptic function may contribute to learning deficits associated with developmental hypothyroidism.

AN - 75761108; 14551995 AB - Aquatic toxicity tests are laboratory experiments that measure the biological effect (e.g., growth, survival, reproduction) of effluents, receiving waters, or storm water on aquatic organisms. These toxicity tests must be performed using the best laboratory practices, and every effort must be made to enhance repeatability of the test method. We evaluated the generated reference toxicant test data for insurance of a level of quality assurance for tests over time within a laboratory and among laboratories. We recommend the reporting and evaluation of the percent minimum significant difference (PMSD) value for all toxicity test results. The minimum significant difference (MSD) represents the smallest difference between the control mean and a treatment mean that leads to the statistical rejection of the null hypothesis (i.e., no toxicity) at each concentration of the toxicity test dilution series. The MSD provides an indication of within-test variability, and smaller values of MSD are associated with increased power to detect a toxic effect. We recommend upper and lower PMSD bounds for each test method in order to minimize within-test variability and increase statistical power. To ensure that PMSD does not exceed an upper bound, testing laboratories may need to increase replication, decrease variability among replicates, or increase the control mean performance.

AN - 73564476; 13678286 AB - Recent wildland fires near two U.S. nuclear facilities point to a need to rapidly identify the presence of airborne plutonium during incidents involving the potential release of radioactive materials. Laboratory turn-around times also need to be shortened for critical samples collected in the earliest stages of radiological emergencies. This note discusses preliminary investigations designed to address both these problems. The methods under review are same day high-resolution alpha spectroscopy to screen air filter samples for the presence of plutonium and inductively coupled plasma mass spectrometry to perform sensitive plutonium analyses. Thus far, using modified alpha spectroscopy techniques, it has been possible to reliably identify the approximately 5.2 MeV emission of 239Pu on surrogate samples (air filters artificially spiked with plutonium after collection) even though the primary alpha-particle emissions of plutonium are, as expected, superimposed against a natural alpha radiation background dominated by short-lived radon and thoron progeny (approximately 6-9 MeV). Several processing methods were tested to prepare samples for analysis and shorten laboratory turn-around time. The most promising technique was acid-leaching of air filter samples using a commercial open-vessel microwave digestion system. Samples prepared in this way were analyzed by both alpha spectroscopy (as a thin-layer iron hydroxide co-precipitate) and inductively coupled plasma mass spectrometry. The detection levels achieved for 239Pu--approximately 1 mBq m(-3) for alpha spectroscopy screening, and, < 0.1 mBq m(-3) for inductively coupled plasma mass spectrometry analysis--are consistent with derived emergency response levels based on EPA's Protective Action Guides, and samples can be evaluated in 36 to 72 h. Further, if samples can be returned to a fixed-laboratory and processed immediately, results from mass spectrometry could be available in as little as 24 h. When fully implemented, these techniques have the potential to provide useful information and improved operational flexibility to emergency planners and first-responders during radiological emergencies.

AN - 71549185; 14986899 AB - Multimetric indices of biotic integrity (IBIs) are commonly used to assess condition of stream fish assemblages, but their ability to monitor trends within streams over time is largely unknown. We assessed the trend detection ability of two IBI formulations (one with traditional scoring and metrics, and one with nontraditional scoring and region-specific metrics) and of similarity and diversity indices using simulations that progressively altered the fish assemblages of 39 streams in the United States mid-Atlantic Highlands region. We also assessed responses to simulated 50% variability in fish abundances, as a measure of background "noise." Fish assemblage indices responded little to changes that affected all species proportionally despite substantial changes in total fish number. Assemblage indices responded better to scenarios that differentially affected fish species, either according to life history traits or by increasing dominance of already common species, but even these changes took some time to detect relative to background variability levels. Ordinations of stream fish assemblage data suggested that differences among sites were maintained even after substantial alterations of fish composition within sites. IBIs are designed to detect broad assemblage differences among sites while downplaying abundance changes and variability increases that were the first indications of within-site changes, and they appear more suited to detecting large departures from natural fish assemblages than for monitoring gradual changes such as those our simulations produced. Inferences about causes of assemblage changes should be made with caution because of correlations among species traits and interdependence among IBI component metrics. Site trend assessments should be made based on all available data rather than just by summary indices.

AN - 71466827; 14674581 AB - Isolating and analyzing interstitial water (IW) during sediment toxicity tests enables researchers to relate concentrations of contaminants to responses of organisms, particularly when IW is a primary route of exposure to bioavailable contaminants by benthic dwelling organisms. We evaluate here the precision of sampling IW with the dialysis or 'peeper' method using sediments spiked with five different concentrations of cadmium. This method is one of several that are commonly used for collecting IW. Seven consecutive ten-day toxicity tests were conducted on these sediments and IW samples were collected at the end of each of these tests. Prior to each test initiation and insertion of IW samplers, sediments were allowed to equilibrate for seven days under flow-through conditions with filtered seawater. At the end of each ten-day testing period, peepers were retrieved, and IW cadmium measured. Data sets were organized by treatment and test number. Coefficients of variation (CV) for the six replicates for each sediment and testing period and for each sediment across testing periods (42 replicates) was used as a measure of sampling precision. CVs ranged from 25 to 206% when individual testing periods were considered, but ranged from 39 to 104% when concentrations for all testing periods were combined. However, after removal of outliers using Dixon's Criteria, the CVs improved and ranged from 6 to 88%. These levels of variability are comparable to those reported by others. The variability shown is partially explained by artifacts associated with the dialysis procedure, primarily sample contamination. Further experiments were conducted that support our hypothesis that contamination of the peeper causes much of the variability observed. If method artifacts, especially contamination, are avoided the dialysis procedure can be a more effective means for sampling IW metal.

AN - 71337514; 14604330 AB - The U.S. Environmental Protection Agency's National Exposure Research Laboratory is pursuing a project to improve the methodology for modeling human exposure to motor vehicle emissions. The overall project goal is to develop improved methods for modeling the source through the air pathway to human exposure in significant exposure microenvironments. Current particulate matter (PM) emission models, particle emission factor model (used in the United States, except California) and motor vehicle emission factor model (used in California only), are suitable only for county-scale modeling and emission inventories. There is a need to develop a site-specific real-time emission factor model for PM emissions to support human exposure studies near roadways. A microscale emission factor model for predicting site-specific real-time motor vehicle PM (MicroFacPM) emissions for total suspended PM, PM less than 10 microm aerodynamic diameter, and PM less than 2.5 microm aerodynamic diameter has been developed. The algorithm used to calculate emission factors in MicroFacPM is disaggregated, and emission factors are calculated from a real-time fleet, rather than from a fleet-wide average estimated by a vehicle-miles-traveled weighting of the emission factors for different vehicle classes. MicroFacPM requires input information necessary to characterize the site-specific real-time fleet being modeled. Other variables required include average vehicle speed, time and day of the year, ambient temperature, and relative humidity.

The method was applied to detect BTEXC in a sample collected from the surface, or 5 cm depth of water. Two-hundred milliliters of n-hexane-pretreated and filtered water samples were applied directly to a C18 SPE column. BTEXC were extracted with dichloromethane and the BTEX concentrations were obtained to be 0.1 to 0.37 microg ml(-1). The highest concentration of benzene was found as 0.37 microg ml(-1) with a relative standard deviation (RSD) of 6.2%; cumene was not detected. The factors influencing SPE e.g., adsorbent types, sample load volume, eluting solvent, headspace and temperatures, were investigated. A cartridge containing a C18 adsorbent and using dichloromethane gave a better performance for the extraction of BTEXC from water.

AN - 71256908; 14550757 AB - Environmental regulations aimed at reducing cancer risks usually have the effect of reducing exposure to a carcinogen at the time the regulation is implemented. The reduction of cancer risk may occur shortly after the reduced exposure or after a considerable period of time. The time of risk reduction associated with exposure reduction will vary by compound. Some recommended measures of the economic benefits associated with environmental regulations are sensitive to the timing of the risk reductions and cannot be effectively addressed by the conventional dose-response procedures. This paper introduces the concept and methodologies for calculating cessation lag effects, with the specific goal of answering the following questions: (1) How many cancer cases are avoided at age t after cessation (or reduction) of exposure concentration? and (2) How long does the effect of an exposure last after exposure has terminated (or been reduced)? The proposed procedures do not require more information than what is required by the conventional dose-response procedures for which cumulative or an averaged lifetime exposure is used.

Previous investigations of drinking water from wells in the fractured crystalline bedrock encountered persistent elevated total arsenic. Such contamination may be related to discharging ground water from fractured zones in the basin. Modeled discharge rates greater than +10 cm/yr and super(18)O values lighter than -9.5 per mil VSMOW may indicate recent recharge is mixing with deeper ground water and is focused along some fractured zones in arsenic bearing crystalline rocks.

The catchment is 255 ha in area and has experienced extensive soil erosion and losses of nutrients from intensive vegetable cultivation, irrigated dairy pasture and poultry farms. Simulations of nitrogen and phosphorus loads in the Currency Creek catchment were performed at various temporal scales and the degree of calibration was quantified by comparing the simulated data with the monitoring results. In addition, the model independent, nonlinear parameter estimation code PEST, was applied for sensitivity testing to determine and assess the relative importance of the key parameters of the model. Event flows were simulated satisfactorily with AnnAGNPS but only moderate accuracy was achieved for prediction of event-based nitrogen and phosphorus exports. The biggest deviations from the measured data were observed for daily simulations but trends in the generated nutrients matched observed data. Despite achieving good resemblance between measured and predicted phosphorus loads the model showed high level of sensitivity to assigned pH values for topsoil. Increase in pH by one unit resulted in up to 34% increase in model generated particulate phosphorus load.

Often, benthic production has been considered to be important primarily in shallow systems or as a subsidy to planktonic food web pathways. Stable isotope food web analyses of two arctic lakes (NE14 and I minus) in the Toolik Lake region of Alaska indicate that benthos are the primary source of carbon for adults of all species of benthic and pelagic fish present. We found no effect of turbidity, which may suppress benthic algae by shading, on food web structure. Even though Secchi transparency varied from 10.2 m in NE14 to 0.55-2.6 m in I minus, food webs in both lakes were based upon benthos, had four trophic levels, and culminated with omnivorous lake trout. We suggest that the importance of benthos in the food webs of these lakes is due to their extreme oligotrophy, resulting in planktonic resources that are insufficient for the support of planktivorous consumers.

A validated measure of cognitive function in human infants that also has a homologous or parallel test in laboratory animal studies will provide a valuable approach for large-scale studies. Such a comparable test will allow researchers to observe the effect of environmental neurotoxicants in animals and relate those findings to humans. In this article, we present the results of a review of post-1990, peer-reviewed literature and current research examining measures of cognitive function that can be applied to both human infants (0-12 months old) and laboratory animals. We begin with a discussion of the definition of cognitive function and important considerations in cross-species research. We then describe identified comparable measures, providing a description of the test in human infants and animal subjects. Available information on test reliability, validity, and population norms, as well as test limitations and constraints, is also presented.

The spring wetlands in the Great Artesian Basin are of conservation significance because they provide habitat for endemic species including fish, invertebrates and plants. Since European settlement massive quantities of water have been artificially extracted through bores, reducing spring-flows. Records of the springs of the Queensland section of the Great Artesian Basin (excluding Cape York Peninsula) were compiled from a range of historical sources. Most remaining active springs were visited and surveyed, the physical attributes of the springs described and their current status determined. Recharge springs occur in areas where the evidence suggests the basin is recharged by rainfall and 93% of the original 245 spring-groups in these areas are still active. Discharge springs occur in sections of the Basin down-gradient of the recharge areas and only 36% of the original 300 spring-groups in these areas have at least some springs that are still active. The capping of bores could provide a partial restoration of artesian pressure and enhance spring flows. Of the active spring-groups surveyed 26% have suffered major or total damage as a result of excavation of the wetlands. An emerging threat is the use of exotic grasses as ponded pastures, which have the ability to dominate the habitat of spring wetlands. The potential impacts of other threats including those associated with stock, exotic animals and fire are also discussed. Mitigating these threats requires a conservation strategy that seeks to protect remaining springs with high conservation values.

Striped bass tissue and scale samples were collected from Rhode Island coastal waters during 1996 and archived scale samples (1982-1997) were obtained from Chesapeake Bay. Known striped bass prey items were also collected from Chesapeake Bay and analysed for delta super(13)C. A significant correlation was observed between carbon isotope ratios in striped bass scales and muscle tissue (r super(2) = 0.52; P < 0.05). Carbon isotope ratios were enriched (less negative) in scales relative to muscle tissue by about 3ppt. Carbon isotope ratios in archived striped bass scales from Chesapeake Bay increased significantly from -16.7 plus or minus 0.2ppt in 1982 to -15.1 plus or minus 0.3ppt in 1997. Benthic species, especially invertebrates, were isotopically enriched relative to pelagic fish species collected from the main-stem of Chesapeake Bay. Prey samples collected from riverine locations within Chesapeake Bay were isotopically depleted relative to those collected in the open portion of the Bay. The changes in the carbon isotope ratios of the striped bass scales could be related to changes in the relative proportions of pelagic and benthic food items in the diet of striped bass or to changes in the feeding locations of this species. In either case, there have been changes in the feeding behaviour and/or relationships of the striped bass between 1982 and 1997. Such changes may be related to changing ecological conditions within the estuary, which could influence the health of Chesapeake Bay striped bass.

We explore the thesis that a well-designed, tradable runoff allowance system can create economic incentives for landowners to employ low-cost runoff management practices to reduce excess stormwater flow to more ecologically sound levels. Attributes such as percent impervious surface, soil type, and so on, determine a given land parcel's runoff potential and management alternatives and, by extension, its allowance requirements. Using a small watershed in Cincinnati, Ohio, as a case study, we show that a tradable runoff allowance system carries promise as a low-cost method for attaining reductions in storm-water runoff.

The primary objective of this study was to determine the laboratory- derived toxicities of clay flocculation of the toxic dinoflagellate, Karenia brevis, for four common estuarine test species. Phosphatic clay mixed with a coagulant (polyaluminum hydroxy chloride (PAC)) was not acutely or chronically toxic in most cases to infaunal amphipods (Leptocheirus plumulosus and Ampelisca abdita), grass shrimp embryos (Palaemonetes pugio) and larval sheepshead minnows (Cyprinodon variegatus). K. brevis alone (density RANGE = 3880-5060 cells ml super(-1); brevetoxin (Btx) RANGE = 19.8-140.7 mu g l super(-1)) was very toxic to C. variegatus and, to a lesser extent, L. plumulosus. The addition of clay-coagulant did not usually reduce this toxicity. The combination of clay, coagulant and K. brevis cells when settled over a natural sediment were usually as toxic to the benthic test species as K. brevis alone. This result suggests that clay flocculation of K. brevis blooms will neither increase, nor decrease toxicity to benthic organisms relative to that attributable to an untreated bloom. Validation of this conclusion, however, is required since it is based on laboratory-derived, single species toxicity data using media collected from a simulated red tide event. The determination of environmental effects on indigenous benthic biota in near-coastal areas during a natural red tide event, prior to and after treatment with clay flocculation, would provide the perspective needed for a more realistic hazard assessment of this possible control procedure.

Ten legume species were tested, comprising both native and exotic species. The ten species responded variously to the treatments. Brief exposure to temperatures between 80 and 100 degree C was found to break the seed dormancy of the native ephemeral herbs Chamaecrista mimosoides, Crotalaria calycina, Crotalaria montana, Indigofera hirsuta and Tephrosia juncea, as well as the exotic ephemeral herb Crotalaria lanceolata. Exposure to 80 degree C combined with treatment with a nitrate solution produced an additive effect on the germination of Chamaecrista mimosoides and Crotalaria lanceolata. However, the four species with the heaviest seeds, two exotic ephemeral herbs (Chamaecrista absus and Crotalaria pallida) and two native perennials (Galactia tenuiflora and Glycine tomentella) displayed no significant increase in germination with exposure to fire-related cues. Exposure to 120 degree C for 5 min produced seed mortality in all species tested. Two of the largest seeded species, Crotalaria pallida and Galactia tenuiflora, displayed the lowest tolerance to heat shock, with seed mortality after exposure to 100 degree C for 5 min. These data indicate that fire can promote the germination of some tropical savanna legumes. As a proportion of seeds of each species displayed no innate dormancy, some germination may occur in the absence of fire, especially of exotic species.

About 20% of the differences could be attributed to changes in the predictions of extinction probability. Most differences arose from refinement of ICUN Red List Categories and Criteria. Research showed that some populations were more threatened than realised and a few changes resulted from taxonomic revision. Funds might have been distributed differently had the adjusted analysis been available in 1992. Nevertheless, comparisons between either the original or the revised 1992 list and the 2000 list demonstrate degeneration in overall status of threatened birds in Australia. It is concluded that trends in conservation status are a valid long-term measure of the risk of biodiversity loss. Stabilisation of IUCN Red List definitions should mean that an increasing proportion of the status flux should be attributable to real changes in extinction probability.

Current concerns about degradation of reef environments and alteration of the hydrologic and sediment cycles place the issue at a focal point of multiple environmental concerns. We use a geospatial clustering of a coastal zone database of river and local runoff identified with 0.5 degree grid cells to identify areas of high potential runoff effects, and combine this with a database of reported coral reef locations. Coastal cells with high runoff values are much less likely to contain reefs than low runoff cells and GIS buffer analysis demonstrates that this inhibition extends to offshore ocean cells as well. This analysis does not uniquely define the effects of sediment, since salinity, nutrients, and contaminants are potentially confounding variables also associated with runoff. However, sediment effects are likely to be a major factor and a basis is provided for extending the study to higher resolution with more specific variables.

However, there is no mathematical theory embodying these concepts, although one would be immensely valuable in humanity's efforts to manage the environment. The concept of sustainability applies to integrated systems comprising humans and the rest of nature; the structures and operation of the human component (society, economy, law, etc.) must be such that they reinforce the persistence of the structures and operation of the natural component (ecosystem trophic linkages, biodiversity, biogeochemical cycles, etc.). One of the challenges of sustainability research lies in linking measures of ecosystem functioning to the structure and operation of the associated social system. We review the nature of this complex system including its ecological, social, economic, and technological aspects, and propose an approach to assessing sustainability based on Information Theory that bridges the natural and human systems. These principles are then illustrated using a model system with an ecological food web linked to a rudimentary social system.

Although true gliding motility has not been observed in Sun4, this strain does exhibit a spreading colony morphology when grown on R2A agar. Strain Sun4 has been identified by 16S rRNA sequencing and phylogenetic analysis as belonging to the genus Flavobacterium, and is most closely related to Cytophaga sp. strain Type 0092 and associated Flavobacterium columnare strains. Lipid analysis also identified fatty acids characteristic of the Cytophaga-Flavobacterium group of bacteria. In culture, Sun4 is able to degrade casein and cellulose, but not chitin, gelatin, starch, or agar. Degradation of Giardia cysts by Sun4 appears to require direct cellular contact as neither cell-free extracts nor cells separated from the cysts by dialysis membranes showed any activity against cysts. Activity against Giardia cysts is rapid, with Sun4 killing over 90% of cysts within 48 h. Strain Sun4 requires elevated levels of Ca super(2+) for optimal growth and degradative activity against Giardia cysts. We propose that bacterial strains such as Sun4 could be used as biological control agents against Giardia cysts in drinking water treatment systems.

Over 800 probability-based stations were monitored in four main estuarine systems--Chesapeake Bay, the Delaware Estuary, Maryland and Virginian coastal bays, and the Albemarle-Pamlico Estuarine System. Twelve smaller estuaries within the four main systems were also assessed to establish variance at the local scale. A subset of the MAIA-Estuaries data is used here to estimate the extent of eutrophication, sediment contamination, and benthic degradation in mid-Atlantic estuaries. An Environmental Report Card and Index of Environmental Integrity summarize conditions in individual estuaries, the four estuarine systems, and the entire MAIA region. Roughly 20-50% of the region showed signs of eutrophication (high nutrients, excessive production of organic matter, poor water clarity, or depleted dissolved oxygen), 30% had contaminated sediments, and 37% had degraded benthic communities. Compared with the Environmental Monitoring and Assessment Program (EMAP)-Virginian Province study in 1990-1993, larger fractions of Chesapeake Bay (17%) and Delaware River (32%) had increased metals or organics in sediments.

However, the disposition of arsenic after repeated exposure is not well known. This study examined the disposition of arsenic after repeated po administration of arsenate. Whole-body radioassay of adult female B6C3F1 mice was used to estimate the terminal elimination half-life of arsenic after a single po dose of [ super(73)As]arsenate (0.5 mg As/kg). From these data, it was estimated that steady-state levels of whole-body arsenic could be attained after nine repeated daily doses of [ super(73)As]arsenate (0.5 mg As/kg). The mice were whole-body radioassayed immediately before and after the repeated dosing. Excreta were collected daily and analyzed for arsenic-derived radioactivity and arsenicals. Whole-body radioactivity was determined 24 h after the last repeated dose, and five mice were then euthanized and tissues analyzed for radioactivity. The remaining mice were whole-body radioassayed for 8 more days, and then their tissues were analyzed for radioactivity. Other mice were administered either a single or nine repeated po doses of non-radioactive arsenate (0.5 mg As/kg). Twenty-four hours after the last dose, the mice were euthanized, and tissues were analyzed for arsenic by atomic absorption spectrometry (AAS). Whole-body radioactivity was rapidly eliminated from mice after repeated [ super(73)As]arsenate exposure, primarily by urinary excretion in the form of dimethylarsinic acid (DMA(V)). Accumulation of radioactivity was highest in bladder, kidney, and skin. Loss of radioactivity was most rapid in the lung and slowest in the skin. There was an organ-specific distribution of arsenic as determined by AAS. Monomethylarsonic acid was detected in all tissues except the bladder. Bladder and lung had the highest percentage of DMA(V) after a single exposure to arsenate, and it increased with repeated exposure. In kidney, iAs was predominant. There was a higher percentage of DMA(V) in the liver than the other arsenicals after a single exposure to arsenate. The percentage of hepatic DMA(V) decreased and that of iAs increased with repeated exposure. A trimethylated metabolite was also detected in the liver. Tissue accumulation of arsenic after repeated po exposure to arsenate in the mouse corresponds to the known human target organs for iAs-induced carcinogenicity.

AN - 75755102; 14535309 AB - To evaluate the importance of both the inorganic and organic fractions in biosolids on Cd chemistry, a series of Cd sorption and desorption batch experiments (at pH 5.5) were conducted on different fractions of soils from a long-term field experimental site. The slope of the Cd sorption isotherm increased with rate of biosolids and was different for the different biosolids. Removal of organic carbon (OC) reduced the slope of the Cd sorption isotherm but did not account for the observed differences between biosolids-amended soils and a control soil, indicating that the increased adsorption associated with biosolids application was not limited to the increased OC from the addition of biosolids. Removal of both OC and Fe/Mn further reduced the slopes of Cd sorption isotherms and the sorption isotherm of the biosolids-amended soil was the same as that of the control, indicating both OC and Fe/Mn fractions added by the biosolids were important to the increased sorption observed for the biosolids-amended soil samples. Desorption experiments failed to remove from 60 to 90% of the sorbed Cd. This "apparent hysteresis" was higher for biosolids-amended soil than the control soil. Removal of both OC and Fe/Mn fractions was more effective in removing the observed differences between the biosolids-amended soil and the control than either alone. Results show that Cd added to biosolids-amended soil behaves differently than Cd added to soils without biosolids and support the hypothesis that the addition of Fe and Mn in the biosolids increased the retention of Cd in biosolids-amended soils.

AN - 75744652; 14524539 AB - We used geospatial techniques to study the potential impact of 2 exotic mosquitoes, Aedes albopictus and Ochlerotatus japonicus japonicus, on the epidemiology of West Nile virus in Maryland. These 2 species have established populations in Maryland over the past 15 years. Larvae of both mosquito species are found in natural and artificial water-holding cavities and containers, particularly water in tires. Therefore, we used locations of licensed tire dealers and of tire dumps scheduled for clean up as an index for potential sources of mosquito vectors. This index was expected to underestimate the actual population of source habitats. West Nile virus activity in Maryland during 1999, 2000, and 2001 was indicated by the presence of dead, infected birds, particularly American crows and other corvids; infected pools of mosquitoes; and human and horse infections. Adult females of both mosquito species are aggressive, opportunistic feeders that have been observed to take blood meals from avian and mammalian hosts. Susceptible vertebrate hosts, particularly birds, are ubiquitously distributed throughout the developed areas of the state. This analysis demonstrated a spatial convergence of the virus, the exotic mosquito vectors, and susceptible hosts. This conjunction indicated that these 2 mosquito species have a high potential to serve as bridge vectors and thus, impact the epidemiology of West Nile virus under favorable environmental and climatic conditions. Positive mosquito pools were collected from only the Baltimore-Washington metropolitan corridor, suggesting a newly created enzootic focus for this virus. Land-cover analysis of the sites where virus activity had been detected showed predominantly developed land uses. Analyses of the environmental justice aspects (social, economic, and housing characteristics) of block groups with human West Nile fever cases or with positive mosquito pools were equivocal. Human cases seemed to occur in developed block groups with lower income levels.

AN - 73623835; 12959524 AB - A mercury (Hg) saturation assay for measuring metallothionein (MT) in fish liver was modified by optimizing binding conditions to minimize the mercury and tissue consumed. The revised method uses stable Hg at low concentrations instead of 203Hg. At the reduced Hg concentrations used, MT concentrations in livers homogenized in saline appeared to increase systematically with dilution in both bluegill sunfish (Lepomis macrochirus) and largemouth bass (Micropterus salmoides). This error suggested a binding limitation due to sulfhydryl oxidation or competition for and removal of mercury by non-MT proteins. Homogenizing tissues in trichloroacetic acid (TCA) eliminated the interference. To further evaluate the method, the protocol was tested in the laboratory and field. Metallothionein in bluegill injected with 0.6 mg/kg zinc chloride increased at a rate of 0.03 nmole MT/g liver/h (r2 = 0.53, p = 0.001). Linearity improved when data were corrected for protein content (r2 = 0.74, p < 0.0001). Metallothionein levels in bluegill from a coal ash-contaminated environment were significantly increased over that of hatchery-reared sunfish (F = 20.17, p = 0.0003). The microscaled procedure minimizes concerns related to radioisotope use and waste generation while retaining the high sensitivity of the 203Hg assay.

AN - 73610598; 12933695 AB - Thyroid hormones are essential for neonatal brain development. It is well established that insufficiency of thyroid hormone during critical periods of development can impair cognitive functions. The mechanisms that underlie learning deficits in hypothyroid animals, however, are not well understood. As impairments in synaptic function are likely to contribute to cognitive deficits, the current study tested whether thyroid hormone insufficiency during development would alter quantitative characteristics of synaptic function in the hippocampus. Developing rats were exposed in utero and postnatally to 0, 3, or 10 ppm propylthiouracil (PTU), a thyroid hormone synthesis inhibitor, administered in the drinking water of dams from gestation d 6 until postnatal day (PN) 30. Excitatory postsynaptic potentials and population spikes were recorded from the stratum radiatum and the pyramidal cell layer, respectively, in area CA1 of hippocampal slices from offspring between PN21 and PN30. Baseline synaptic transmission was evaluated by comparing input-output relationships between groups. Paired-pulse facilitation, paired-pulse depression, long-term potentiation, and long-term depression were recorded to examine short- and long-term synaptic plasticity. PTU reduced thyroid hormones, reduced body weight gain, and delayed eye-opening in a dose-dependent manner. Excitatory synaptic transmission was increased by developmental exposure to PTU. Thyroid hormone insufficiency was also dose-dependently associated with a reduction paired-pulse facilitation and long-term potentiation of the excitatory postsynaptic potential and elimination of paired-pulse depression of the population spike. The results indicate that thyroid hormone insufficiency compromises the functional integrity of synaptic communication in area CA1 of developing rat hippocampus and suggest that these changes may contribute to learning deficits associated with developmental hypothyroidism.

AN - 73603627; 12948975 AB - This study investigated the scale of the public health risk from stormwater runoff caused by urbanization. We compiled turbidity data for municipal treated drinking water as an indication of potential risk in selected US cities and compared estimated costs of waterborne disease and preventive measures. Turbidity levels in other US cities were similar to those linked to illnesses in Milwaukee, Wis, and Philadelphia, Pa. The estimated annual cost of waterborne illness is comparable to the long-term capital investment needed for improved drinking water treatment and stormwater management. Although additional data on cost and effectiveness are needed, stormwater management to minimize runoff and associated pollution appears to make sense for protecting public health at the least cost.

AN - 73397300; 12850101 AB - This article reviews the state of the science regarding the health effects of polybrominated dibenzo-p-dioxins (PBDDs) and dibenzofurans (PBDFs). While thousands of articles have been published on the health effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin and related polychlorinated dibenzodioxins (PCDDs) and dibenzofurans (PCDFs), little is know about the brominated and mixed chloro/bromo homologs. Available literature suggests that brominated compounds have similar toxicity profiles to their chlorinated homologs. However, further research investigating health effects will only be useful if exposure scenarios truly exist. Current exposure data is extremely limited, posing a major data gap in assessing potential risk of these chemicals. The rapid increase in the use of brominated flame retardants has raised the level of environmental concern regarding PBDDs/PBDFs as it is likely that human, as well as wildlife, exposure to brominated dioxins and furans will increase with their use.

AN - 71323491; 14582718 AB - The form of the dose-response curve for radiation-induced cancers, particularly at low doses, is the subject of an ongoing and spirited debate. The present review describes the current database and basis for establishing a low dose, linear no threshold (LNT) model. The requirement for a dose-response model to be used for risk assessment purposes is that it fits the great majority of data derived from epidemiological and experimental tumour studies. Such is the case for the LNT model as opposed to other nonlinear models. This view is supported by data developed for radiation-induced mutations and chromosome aberrations. Potential modifiers of low dose cellular responses to radiation (such as adaptive response, bystander effects and genomic instability) have not been shown to be associated with tumour development. Such modifiers tend to influence the slope of the dose-response curve for cellular responses at low doses and not the shape--thereby resulting in a quantitative modification rather than a qualitative one. Additional data pertinent to addressing the shape of the tumour dose-response relationship at low doses are needed.

AN - 71263886; 14555197 AB - Oral exposures to high concentrations of the drinking water disinfection by-product dibromoacetic acid (DBA) over the course of 14 days have been found to disrupt estrous cyclicity in the female rat. In order to investigate possible alterations in the relevant hormonal regulatory mechanisms, female Sprague-Dawley rats were gavaged for 2 weeks with 270 mg/kg DBA, ovariectomized (OVX) and implanted with estradiol capsules. For these females, the induced luteinizing hormone (LH) surge in these animals showed a borderline suppression in peak LH concentrations that was accompanied by a marked increase in circulating estradiol. This elevation in estradiol was DBA dose-related and, for intact, normally cycling females receiving lower doses of DBA (60 and 120 mg/kg, 14 days), was present on the day of estrus, at a time when a dramatic fall from proestrous concentrations is normally evident. Evaluations of liver microsomal cytochrome p450 activity in OVX/estradiol-implanted rats showed a suppression in ethoxyresorufin-O-deethylase (EROD) and pentoxyresorufin-O-deethylase (PROD) activity (indications of the activity of CYP1A and 2B, respectively-two key enzymes in estradiol oxidative metabolism). Phenobarbital (PhB) exposure in these animals did show induction of this activity, but was unable to lower E2 concentrations. This suggests that a DBA-induced suppression in estradiol catabolism is present and may either involve a targeted effect on the estrogen binding site on the CYP2B1/2 and CYP1A genes apart from the PhB-responsive unit, or a second pathway (possibly sulfation) that is not PhB-inducible.

A key component of the equitable development & implementation of environmental policies is the participation of citizens & community-based organizations in the policy process. Such participation rests upon equitable access to agency-generated environmental information & effective use of that information by citizens. This article focuses on the adoption of Internet technologies by environmental agencies as a mechanism for disseminating information & the implications for low-income & minority residents in urban communities. A framework is developed to guide a programmatic response to overcome these implications. The results from several community-based projects are described & analyzed for their capacity-building effectiveness. Analysis of the projects indicates improvement in community capacity for information access & use, which bolstered community participation in the environmental decision-making process. 1 Table, 41 References.

AN - 51869155; 2004-028645 AB - Surveys have shown that pocosins (swamp-on-a-hill) occur on the southeastern Coastal Plain of the U.S. from Virginia to north Florida and once covered more than one million hectares in North Carolina. A broad definition of pocosins (sensu lato) would include all shrub and forested bogs, as well as Atlantic white cedar stands and some loblolly pine stands on flooded soils on the Coastal Plain. A stricter definition (sensu stricto) of pocosins would only include the classic shrub-scrub (short pocosin) and pond-pine-dominated tall pocosin. Common synonyms for pocosins, including bay, bayland, bayhead, xeric shrub bog, and evergreen shrub bog, further confuse what is and is not classified as a pocosin. Over 51% of the forested palustrine wetlands in North Carolina have been disturbed, with approximately 33% of pocosins having been destroyed. Pocosins are rainfall driven and lack a well-defined stream surface-flow connection to major rivers on the landscape. However, they are often found adjacent to estuaries and have surface hydrologic connections that are linked to the regional water quality and salinity gradients found in estuarine areas along the southeastern coast. This hydrologic connection, combined with the vast continuous expanses of pocosins on the landscape, suggests that they are connected to regulated tributary waters of the United States. In addition, a survey of U.S. Army Corps of Engineers personnel in North Carolina indicates that most pocosins are considered hydrologically connected to regional water supplies since they are the source of water flow on the landscape where they dominate. However, the potential impact of the U.S. Supreme Court's 2001 decision in the case of Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers (SWANCC) on the future development of pocosins is still unknown in most states. Moreover, the Bush administration's recent (January 2003) review and redefinition of the Clean Water Act's (CWA) jurisdiction over isolated wetlands may remove federal oversight on 20% of the nation's wetlands, including pocosins not immediately adjacent to estuaries. The high rate of past wetland loss, especially for pocosin wetlands, suggests that stricter wetland laws are needed at the state and local level if we are to support the concept of "no net loss" of wetlands.

Depressional wetlands completely surrounded by upland have traditionally been called "isolated wetlands". Isolated wetlands are not confined to basins, as some occur on broad flats and others form on slopes. The term "geographically isolated wetlands" better describes these wetlands, since many are hydrologically connected to other wetlands and waterbodies through ground-water flows or by intermittent overflows (spillovers). Numerous types of geographically isolated wetlands occur throughout the United States. They may be naturally formed or the result of human action. Naturally formed types include prairie pothole wetlands, playas, Nebraska's Rainwater Basin and Sandhills wetlands, West Coast vernal pools, sinkhole wetlands, Carolina bays, interdunal and intradunal wetlands, desert springs, terminal basins in the Great Basin, and kettle-hole bogs in glaciated regions. Human-caused isolated types may be intentionally built, such as ponds designed for various purposes and wetlands built on mined lands, or they may be accidentally created (e.g., natural wetlands that were once connected to rivers and streams but are now isolated by roads, railroads, and other development or isolated by altered river hydrology). Many of the functions and benefits attributed to non-isolated wetlands are present in isolated wetlands.

In this paper, we examine water-quality data for isolated wetlands in three hydrogeomorphic classes (depressions, slopes, flats). Some isolated wetlands are dominated by atmospheric exchanges and have little ground-water or surface-water connections with adjacent systems. Other isolated wetlands are dominated by ground-water inputs and have intermittent or continuous hydrologic connections to adjacent systems. Water-quality characteristics of isolated wetlands are highly variable and depend primarily on the sources of water, substrate characteristics, and land uses associated with the wetland watershed. We were unable to identify any general pattern of water-quality characteristics within or between isolated wetlands in the three hydrogeomorphic classes. Alteration of hydrologic conditions (e.g., ditching, filling), however, usually results in increased nutrient export to downstream systems. From a water-quality perspective, we conclude that so-called isolated wetlands are rarely isolated, and isolation is a term that is not very useful from an ecosystem perspective. Isolated wetlands are nutrient sinks and, because most are hydrologically connected to other waters and wetlands, the loss of isolated wetlands would potentially have negative impacts on the water quality of downstream systems.

Although the definition is based on surface-water connections to other water bodies, isolated wetlands commonly are integral parts of extensive ground-water flow systems, and isolated wetlands can spill over their surface divides into adjacent surface-water bodies during periods of abundant precipitation and high water levels. Thus, characteristics of ground-water flow and atmospheric-water flow affect the isolation of wetlands. In general, the degree that isolated wetlands are connected through the ground-water system to other surface-water bodies depends to a large extent on the rate that ground water moves and the rate that hydrologic stresses can be transmitted through the ground-water system. Water that seeps from an isolated wetland into a gravel aquifer can travel many kilometers through the ground-water system in one year. In contrast, water that seeps from an isolated wetland into a clayey or silty substrate may travel less than one meter in one year. For wetlands that can spill over their surface watersheds during periods of wet climate conditions, their isolation is related to the height to a spill elevation above normal wetland water level and the recurrence interval of various magnitudes of precipitation. The concepts presented in this paper indicate that the entire hydrologic system needs to be considered in establishing a definition of hydrologic isolation.

The common denominator among all types of fens is recognition of the importance of ground-water discharge, especially mineral-rich ground water, in determining fen hydrology, chemistry, and vegetation, in contrast to wetlands whose characteristics are determined primarily by precipitation or surface-water inputs. Thus, fens tend to occur where climate and hydrogeologic setting sustain flows to the plant-rooting zone of mineral-rich ground water. In the United States, these areas include the glaciated Midwest and Northeast, as well as portions of the Appalachian Mountains and mountainous West. Individually and collectively, fens are among the most floristically diverse of all wetland types, supporting a large number of rare and uncommon bryophytes and vascular plant species, as well as uncommon animals including mammals, reptiles, land snails, butterflies, skippers, and dragonflies. Several species listed under the federal Endangered Species Act inhabit or use fens. Fens also help maintain stream water quality through denitrification and phosphorus sorption. Few estimates of loss and current extent exist, but where estimates are available, they indicate extensive loss, fragmentation, and degradation. Cultural eutrophication threatens the biological and functional integrity of remaining fens because, along with mineral-rich water, low availability of nitrogen and phosphorus controls many of their distinctive characteristics. Because they occur where ground water discharges to the surface, fens are isolated from neither ground water nor surface water. However, the majority of fens develop in headwater areas and could be defined as "isolated" for jurisdictional purposes because of their distance from navigable-in-fact waters. If so defined, the critical roles that fens play in maintaining biological diversity and stream water quality are at risk regarding federal jurisdiction over "isolated waters" because of the 2001 U.S. Supreme Court ruling in the case of Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers.

The individual was observed three times over a period of 5 days. The timing of the observation in the annual cycle of this species suggests this to be the first reported example of singing by a female Canada Warbler. Previous reports of female song in the congeneric Wilson's Warbler (Wilsonia pusilla) and Hooded Warbler (Wilsonia citrina) support this inference.

To investigate the variability and significant differences in ACRs, an extensive data set was compiled of 456 same-species pairs of acute and maximum acceptable toxicant concentrations for metals, narcotics, pesticides, and other organic chemicals. The overall median value for 456 aquatic invertebrate and fish ACRs analyzed in the present study was 8.3, with a 16,000-fold range in values (1.1- 18,550) and a 32-fold range in 10th and 90th percentile values (2.5-79.5). Median ACRs for taxa, ambient habitat media, chronic test end point, and chemical mode of action (MOA)/class categories generally were similar but, in some cases, extremely variable (ranges of 1 to >10,000). No significant differences (p le 0.05) were found in median ACRs between taxa, although invertebrate ACRs generally were more variable than fish ACRs. Freshwater organisms had median ACRs significantly greater than those of saltwater species and also were more variable. No significant differences were found in median ACRs among chemical MOA/class data sets; however, ACR variance differed significantly among MOAs. Although few significant differences occurred among median ACRs for different groups, those categories that were highly variable are at an increased risk of underestimated chronic toxicity when mean or median ACRs are used.

Evidence, however, exists that fish sex steroid hormone receptors differ from mammalian receptors both structurally and in their binding affinities for some steroids and environmental chemicals. Most of the binding studies to date have been conducted using cytosolic preparations from various tissues. In the present study, we compare competitive binding of a set of compounds to full-length recombinant rainbow trout androgen receptor alpha (rtAR), fathead minnow androgen receptor (fhAR), and human androgen receptor (hAR), each expressed in COS cells. Saturation binding and subsequent Scatchard analysis using [ super(3)H]R1881, a high-affinity synthetic androgen, revealed an equilibrium dissociation constant (K sub(d)) of 0.11 nM for the rtAR, 1.8 nM for the fhAR, and 0.84 nM for the hAR. Compounds, including endogenous and synthetic steroids, known mammalian antiandrogens, and environmental compounds, were tested for competitive binding to each of the three receptors. Overall, agreement existed across receptors as to binding versus nonbinding for all compounds tested in this study. Minor differences, however, were found in the relative order of binding of the compounds to the individual receptors. Studies such as these will facilitate the identification of EDCs that may differentially affect specific species and aid in the development and support of future risk assessment protocols.

The loading of large amounts of these chemicals into Lake Ontario during the middle of the 20th century coincided with a population decline that culminated in extirpation of this species around 1960. Prediction of past TCDD toxicity equivalence concentrations in lake trout eggs (TEC sub(egg)s) relative to recent conditions required fine resolution of radionuclide-dated contaminant profiles in two sediment cores; reference core specific biota-sediment accumulation factors (BSAFs) for TCDD-like chemicals in lake trout eggs; adjustment of the BSAFs for the effect of temporal changes in the chemical distributions between water and sediments; and toxicity equivalence factors based on trout early life stage mortality. When compared to the dose-response relationship for overt early life stage toxicity of TCDD to lake trout, the resulting TEC sub(egg)s predict an extended period during which lake trout sac fry survival was negligible. By 1940, following more than a decade of population decline attributable to reduced fry stocking and loss of adult lake trout to commercial fishing, the predicted sac fry mortality due to AHR-mediated toxicity alone explains the subsequent loss of the species. Reduced fry survival, associated with lethal and sublethal adverse effects and possibly complicated by other environmental factors, occurred after 1980 and contributed to a lack of reproductive success of stocked trout despite gradually declining TEC sub(egg)s. Present exposures are close to the most probable no observable adverse effect level (NOAEL TEC sub(egg) = 5 pg TCDD toxicity equivalence/g egg). The toxicity predictions are very consistent with the available historical data for lake trout population levels in Lake Ontario, stocking programs, and evidence for recent improvement in natural reproduction concomitant with declining levels of persistent bioaccumulative chemicals in sediments and biota.

Analysis of the concentrations of toxic organic compounds, contaminant and crustal metals, organic carbon content and isotopic composition in sediment cores from two estuarine systems in Buzzards Bay allowed reconstruction of human impacts over 350 years. Vertical distributions of the contaminants correlate with changes in the nature of watershed/estuarine activities. All contaminants were highly enriched (tens to hundreds times background) in modern New Bedford Harbor sediments. Enrichment began around the turn of the 20th century for all but PCBs, which were first synthesized in the 1930s. An increase in organic carbon content and a shift of carbon isotopes toward a more terrestrial signature illustrates increasing anthropogenic impact in New Bedford as population grew along with the industrial base. Institution of environmental protection measures in the late 20th century was reflected in decreased, although still substantially elevated, concentrations of contaminants. A lack of industrial development in Apponagansett Bay resulted in much lower concentrations of the same indicators, although specific contaminants related to the early whaling industry increased significantly above background as early as the late 18th century. The similarity of indicators in older portions of cores from NBH and unimpacted Apponagansett Bay demonstrates that cores can be used to establish reference conditions as successfully as using separate sites judged a priori to represent the reference state. The historical reconstruction approach provides the basis for establishing relationships between environmental stressors and factors that drive the stressors, as well as a framework for the assessment of ecological response(s) to environmental stressors over a range of time and/or exposure scales.

U.S. Army Corps of Engineers (SWANCC) has had profound implications on the legal status of isolated wetlands. As a result, policymakers need ecological information on the definition and functions of isolated wetlands to respond to this decision. The term 'isolated wetlands' is of fairly recent usage and has been poorly defined. In response, I recommend definition as wetlands 'that are completely surrounded by upland.' Isolation needs to be considered with respect to specific processes and functions. I suggest that isolation not be viewed discretely but be considered within an isolation-connectivity continuum. Isolation has a fundamental influence on the way water enters and leaves a wetland. This consequently affects any wetland function that depends on water as a vector (e.g., pollutant transport and certain types of dispersal). These wetlands can also have a high level of endemism, extensive plant zonation, and high biodiversity. Isolated wetlands, however, do not represent ecologically isolated habitat for many organisms. I conclude that the effect of isolation may not be as significant as the term 'isolated wetlands' suggests: many of the biological features of isolated wetlands may result from environmental conditions that also occur in non-isolated wetlands. As a result of SWANCC, assessment methods are needed that can help regulators distinguish between jurisdictional and non-jurisdictional isolated wetlands. I propose that the merger of simple, source-sink-transport vector concepts with landscape-level assessment methods could be useful in this regard. I point to the need for documented examples of organisms that spend most of their lives in waters of the U.S. but also require isolated wetlands. I conclude that wetland science would benefit from the development of a comprehensive view of isolation as a formative process across different regional wetland types.

Current guidance covers inactivation levels in the pH range between 6 and 9. Subsequent to the publication of these criteria, studies on the inactivation kinetics of Giardia cysts by chlorine have been performed at pH levels greater than 9. It has been shown that the chlorine inactivation process for Giardia cysts is pH dependent. The objective of this paper is to extend the current Ct values for higher pH levels. The Chick-Watson first order kinetics model was used to develop Ct values for pH levels from 6 to 11.5. A formula is provided to calculate a 100(1- alpha )% upper confidence bound for these values.

Human caliciviruses (HuCVs) were suspected as the etiological agent of the outbreak based on the incubation period, duration of illness, and symptoms observed in ill patrons. A retrospective cohort study demonstrated that ill patrons were 4.5 times more likely to have exposure to drinking water and/or ice than nonill patrons. No food items were associated with illness. An environmental investigation gave evidence that the saloon's groundwater was contaminated with sewage. Water from the saloon's only well was processed for viruses. The processed water sample and stool samples collected from three ill patrons were analyzed by reverse transcription-PCR (RT-PCR) for the presence of HuCV. All positive RT-PCR results were confirmed by sequence and phylogenetic analyses of cloned RT-PCR products. A genogroup I, subtype 3, HuCV stain was found to be present in the well water sample and two stool samples. In addition, a genogroup II, subtype 6, strain was detected in one stool sample. The identification of the same HuCV strain in both the well water and stool samples strongly suggests a link between exposure to well water and the outbreak of gastroenteritis. The presence of a genogroup II, subtype 6, strain in one of the stool samples suggests that multiple HuCV strains may have been involved in this outbreak. The laboratory isolation of HuCV strains from outbreak-associated drinking water is relatively novel in the United States. This investigation outlines the procedure for virus isolation and illustrates the utility of RT-PCR for the identification of HuCV in large volumes of water and stool samples obtained during outbreaks of acute nonbacterial gastroenteritis.

Sparse or inadequate data limit the extent to which nutrient exports may be estimated from direct observations. The paucity of data for calibration and simulation limits the use of sophisticated models in most Australian catchments. Therefore, a simple unit-area load model-Catchment Management Support System (CMSS)-was selected to estimate aggregated catchment emissions for the NPI. Estimates from models like CMSS are sensitive to spatial and categorical resolution of land uses identified within the catchment and to nutrient generation rates selected for each land use category. Using three Hawkesbury-Nepean subcatchments, we show that while high spatial resolution of land use mapping is useful, only four or five major land use categories with carefully selected generation rates were required to estimate potential nutrient exports sufficiently well and to determine subcatchments contributing most. Nutrient emission estimates proved to be highly dependent on selection of generation rates so a bootstrap technique was adopted to reduce subjectivity and to improve estimates of confidence limits. This led to a specification of new generation rates for Natural, Unimproved pasture, Rural and Urban land uses and to establishment of uncertainty limits.

Samples of fine particulate matter (<2.5 mu m aerodynamic diameter; PM sub(2.5)) collected in Hettstedt in 1999 had several-fold higher levels of zinc, magnesium, lead, copper, and cadmium than samples from Zerbst. To determine if the results from epidemiologic studies could be repeated in an animal model, we administered PM sub(2.5) from Hettstedt and Zerbst to ovalbumin-allergic mice. In Balb/c mice, PM sub(2.5) from Hettstedt, but not PM sub(2.5) from Zerbst or control filter extract, caused a significant increase in immediate responses to ovalbumin challenge when aspirated 2 hr before challenge, but not when aspirated immediately before sensitization 2 weeks earlier. Antigen-specific IgE was increased by Hettstedt PM sub(2.5) whether administered before sensitization or challenge. Airway responsiveness to methacholine aerosol and lung inflammatory cell numbers were significantly increased only in allergic mice exposed to Hettstedt PM sub(2.5) before challenge. Both Hettstedt and Zerbst PM sub(2.5) significantly increased lung injury parameters and proinflammatory cytokines. These results are consistent with epidemiologic findings and show that metal composition of ambient PM sub(2.5) influences the severity of allergic respiratory disease.

AN - 18948463; 5731234 AB - Bacillus thuringiensis (Bt) is a naturally occurring soil bacterium that produces proteins active against certain insects. Beginning in the mid-1990s, crop plants expressing Bt genes were commercialized in the United States. Cry1Ab and Cry1F Bt corn are effective in controlling certain pests of corn (European corn borer, corn earworm and southwestern corn borer), and Cry1Ac Bt cotton is effective in controlling certain pests of cotton (tobacco budworm, cotton bollworm and pink bollworm). Beyond the economic benefits to growers, the use of Bt corn and Bt cotton result in less risk to human health and the environment than chemical alternatives. In 2001, the US Environmental Protection Agency (EPA; Washington, DC, USA) reassessed the four still registered, but expiring, Bt crops that had been accepted for agricultural use in the preceding six years (from 1995 to October 2001; Table 1). The Bt crop reassessment approvals included provisions to prevent gene flow from Bt cotton to weedy relatives, increase research data on potential environmental effects and strengthen insect resistance management.

Location The study was conducted in a 500 ha pocket of Eucalyptus-dominated savanna surrounded by a late Quaternary lava flow. The flow is known as the Great Basalt Wall, located c. 50 km northeast of Charters Towers in semi-arid north-eastern Australia. This region was exposed to the largest 5-year rainfall deficit on record between 1992 and 1996. Methods All individual woody plants were tagged within a 1.56 ha plot. Species were segregated into their habitat affinities (rain forest, ecotone, savanna) and regeneration strategy (resprouter, seeder). The survivorship of plants within these categories was analysed in relation to fire intensity from the first fire, and to each of four fires lit between 1996 and 2001. Results Before the first fire, the plot contained thirty-one tree species including twenty-one typical of the surrounding dry rain forest. These rain forest species were represented by small individuals and constituted <1% of the total basal area of woody plants. The basal area of savanna trees was 7.5 m super(2) ha super(-1) at the commencement of monitoring, although 31% had recently died and others had major crown damage. Further death of the drought debilitated savanna trees was substantial during the first year of monitoring and the basal area of live savanna trees declined to 1.1 m super(2) ha super(-1) after 5 years. Most species from both rain forest and savanna were classified as resprouters and are capable of regenerating from underground organs after fire. Species without this ability (rain forest seeders and ecotone seeders) were mostly eliminated after the first two consecutive fires. Among resprouters, survivorship declined as fire intensity increased and this was more pronounced for rain forest than for savanna species. Repeated burning produced a cumulative effect of decreasing survivorship for rain forest resprouters relative to savanna resprouters. Main conclusions The study provides evidence that savanna and rain forest trees differ in fire susceptibility and that recurrent fire can explain the restricted distribution of rain forest in the seasonally arid Australian tropics. The time of death of the savanna trees is consistent with the regional pattern after severe drought, and highlights the importance of medium term climate cycles for the population dynamics of savanna tree species and structure of Australian savannas.

Epidemiological studies have shown an association of sub-optimal pregnancy outcomes in one generation with similar events in the following one, a phenomenon termed the 'intergenerational effect'. Data indicate that the incidence of adverse pregnancy outcomes and/or low birth weight infants is more closely correlated with the mother's perinatal environment than with that during her pregnancy. However, epidemiological studies are inherently limited given the variability of lifestyles, ethnicity, nutritional status, and exposures to environmental factors. An appropriate animal model would permit control of parameters that may be impossible to evaluate in human populations. The current studies investigated the mouse as a possible animal model. Pregnant CD-1 mice were placed on an ad libitum or food-restricted diet (50% normal) throughout gestation to generate control (CON) and intrauterine growth retarded (IUGR) litters. At birth (postnatal day (PD) 1) pups (F1) were cross-fostered to control dams in litters of either 8 (CON) or 16 (postnatal food restriction (FR)). The experimental groups thus generated represented adequate nutrition (CON-CON) and undernutrition during the prenatal (IUGR-CON), or postnatal periods (CON-FR), or both (IUGR-FR). Pups of dams on a restricted diet during gestation had significant IUGR (P<0.001) as compared to controls (birth weights of 1.32 g versus 1.63 g). At weaning, the average weight of the pups was dependent on postnatal litter size and the difference in birth weights between IUGR and CON animals was not a significant factor. CON-CON pup weight was 24.1 g and IUGR-CON was 22.2 g as compared to the CON-FR (17.0 g) and IUGR-FR (17.3 g) groups. The difference in weaning pup weights between the FR and CON groups was significant (P<0.01). The F1 FR females did not reach CON female weights at any time point through 11 months after weaning. At PD60, a single breeding period for all groups of females with CON males began and continued for 75 days with 17 opportunities for breeding. Animals that became pregnant during this time were removed and allowed to litter. No significant differences were noted in average F2 litter size or average pup weight at birth: (CON-CON 12.2/1.62 g; IUGR-CON 11.9/1.62 g; CON-FR 10.9/1.70 g; IUGR-FR 11.3/1.61 g). We conclude that body weight at birth in the CD-1 mouse is not correlated with growth through the period of weaning (PD28). We did not find any evidence for an intergenerational reproductive effect after developmental undernutrition.

Streambed stone stability, packing and embeddedness were assessed within and adjacent to beds of the macrophyte Justicia americana in five Alabama streams.The force needed to dislodge stones and embeddedness was about two times lower outside Justicia beds than within them. Significant positive correlations between stone stability and (i) degree of embeddedness, and (ii) the abundance of binding rhizomes and the presence of attached roots indicate that Justicia may physically modify the local streambed, indirectly enhancing substratum stability and reducing flow, thereby increasing sand deposition.Despite higher stability (i.e. physical refugia during bed-moving spates) within Justicia beds, the abundance of epilithic plants (moss and Podostemum ceratophyllum) and pleurocerid snails (Elimia spp.) was similar both inside and outside the macrophyte beds. Several physical characteristics within macrophyte beds, such as low light, reduced current and increased sand intrusion, may create suboptimal conditions for benthic organisms in these habitats.Additional work is needed to determine if Justicia biogenically enhances substratum stability or if its presence merely reflects patches of stable substratum within the streambed. Regardless of the mechanism, there is an association between Justicia beds and streambed characteristics.

The size, height, and spatial distribution of micromounds and surrounding depressions were measured by a modified erosion bridge at three distances (50, 450, and 1050m) from water points in desert grassland pastures in the Jornada Basin, New Mexico, USA. Plots at 50m had fewer micromounds and the mounds were smaller than those recorded on the more distant plots. Microtopography of plots at 450m from water was not significantly different from that recorded at 50m. Microtopography of plots that were 1050m from water points was significantly different from that of plots nearer water points. Strong correlation between microtopography and the cover of long-lived perennial grasses (R super(2)=91%) was found, such dependence could be used for assessing the trend in organic matter content that is in concordance with that of microtopography. Loss of microtopography from the impact of livestock in piospheres exacerbates erosion processes and contributes to desertification.

The choice of an MMU that is appropriate for the projected use of a classification is an important consideration. The objective of this experiment was to determine the effect of MMU on a LC classification of the Neuse River Basin (NRB) in North Carolina. The results of this work indicate that MMU size had a significant effect on accuracy estimates only when the MMU was changed by relatively large amounts. Typically, an MMU is selected as close as possible to the original data resolution so as to reduce the loss of specificity introduced in the resampling process. Since only large MMU changes resulted in significant differences in the accuracy estimates, an analyst may have the flexibility to select from a range of MMUs that are appropriate for a given application.

This study represents the first comprehensive investigation of DBPs formed by chlorine dioxide under high bromide conditions. Drinking water from full-scale treatment plants in Israel was studied, along with source water (Sea of Galilee) treated under carefully controlled laboratory conditions. Select DBPs (trihalomethanes, haloacetic acids, aldehydes, chlorite, chlorate, and bromate) were quantified. Many of the DBPs identified have not been previously reported, and several of the identifications were confirmed through the analysis of authentic standards. Elevated bromide levels in the source water caused a significant shift in speciation to bromine-containing DBPs; bromoform and dibromoacetic acid were the dominant DBPs observed, with very few chlorine-containing compounds found. Iodo-trihalomethanes were also identified, as well as a number of new brominated carboxylic acids and 2,3,5-tribromopyrrole, which represents the first time a halogenated pyrrole has been reported as a DBP. Most of the bromine-containing DBPs were formed during pre-chlorination at the initial reservoir, and were not formed by chlorine dioxide itself. An exception was the iodo-THMs, which appeared to be formed by a combination of chlorine dioxide with chloramines or chlorine (either added deliberately or as an impurity in the chlorine dioxide). A separate laboratory study was also conducted to quantitatively determine the contribution of fulvic acids and humic acids (from isolated natural organic matter in the Sea of Galilee) as precursor material to several of the DBPs identified. Results showed that fulvic acid plays a greater role in the formation of THMs, haloacetic acids, and aldehydes, but 2,3,5-tribromopyrrole was produced primarily from humic acid. Because this was the first time a halopyrrole has been identified as a DBP, 2,3,5-tribromopyrrole was tested for mammalian cell cytotoxicity and genotoxicity. In comparison to other DBPs, 2,3,5-tribromopyrrole was 8x, 4.5x, and 16x more cytotoxic than dibromoacetic acid, 3-chloro-4-(dichloromethyl)-5-hydroxy-2-[5H]-furanone [MX], and potassium bromate, respectively. 2,3,5-Tribromopyrrole also induced acute genomic damage, with a genotoxic potency (299 mu M) similar to that of MX.

SWANCC represented a major reinterpretation of the CWA by re-emphasizing the importance of navigability in the definition of 'waters of the United States' protected by the statute. The decision also implied that isolated waters might be 'waters of the United States' where they had a 'significant nexus' to navigable waters. Understanding the significance of SWANCC requires a historical look at the geographic scope of federal laws and regulations protecting surface waters. The concept of navigability had been prominent in the Rivers and Harbors Act of 1899, but the principal implementation focus for the CWA after its enactment in 1972 and prior to SWANCC had been on the hydrologic cycle and the relevance of links to interstate commerce for determining what waters were protected under the CWA. In upcoming years and months, the geographic jurisdiction of the CWA will continue to be debated in the courts, within Federal agencies, and by the public. Aquatic resource science will play a key role in helping ensure that the CWA is implemented in a scientifically defensible manner, consistent with SWANCC. One area in need of particular emphasis is additional research on the ways in which isolated waters help ensure the physical, chemical, and biological integrity of navigable waters and their tributaries. It is this question-the 'significant nexus' between an intrastate non-navigable isolated water and the rest of the aquatic ecosystem-that will likely determine whether the water will be protected by the CWA.

U.S. Army Corps of Engineers (SWANCC), the U.S. Supreme Court held that isolated, intrastate, non-navigable waters could not be protected under the Clean Water Act based solely on their use by migratory birds. The SWANCC decision has created a need to compile and make available scientific information for post-SWANCC policy development. In response, this article reviews the state of our scientific understanding of isolated wetlands, based on the major findings of papers contributed to this special issue of Wetlands. Because the term 'isolated wetland' has not been used consistently in the scientific literature, we recommend that geographically isolated wetlands be defined as 'wetlands that are completely surrounded by upland,' as proposed by Tiner, for the purposes of scientific studies. Geographically isolated wetlands are not homogeneous but have a broad range of functional response, partly due to their occurrence over a wide range of climatic and geologic settings. One major question addressed through this special issue is the role that isolation plays in the function of geographically isolated wetlands. It appears that isolation is not a primary factor and that many of the functions performed by isolated wetlands are also performed by non-isolated wetlands and non-wetland ecosystems. Variability in moisture conditions plays an important role in the function of many geographically isolated wetlands. However, hydrologic isolation may affect moisture conditions, and biotic isolation could be important for certain populations. Depending on the factor being considered, geographically isolated wetlands are not entirely isolated but are better viewed as occurring within an isolation-connectivity continuum that has both hydrologic and biotic expressions. The juxtaposition of isolation and connectivity occurring in geographically isolated wetlands may represent a semi-isolated state that uniquely shapes these wetlands and their functions. Comprehensive data, designating the number, total area, and functional classification of isolated wetlands, would provide the foundation for monitoring impacts to isolated wetlands. Studies are needed to examine and quantify how isolated wetlands, wetland complexes, and other potentially impacted waters contribute hydrologically, chemically, and biologically to waters of the U.S. Methods to assess and map the degree of connectivity between geographically isolated wetlands and waters of the U.S., based on ground-water travel time, recurrence frequency of intermittent surface-water connections, and home ranges of species that require both types of waters, could be useful for regulators. Whatever policies are developed, scientific input and technical information will continue to play a crucial role in the policy and regulatory arena. Maintaining and enhancing the dialogue among wetland scientists, policy-makers, and regulators will ensure that critical information is developed and communicated and also continue to invigorate wetland science.

AN - 1859421854; 12915002 AB - Animal models of human cognitive processes are essential for studying the neurobiological mechanisms of these processes and for developing therapies for intoxication and neurodegenerative diseases. A discrete-trial signal detection task was developed for assessing sustained attention in rats; a previous study showed that rats perform as predicted from the human sustained attention literature. In this study, we measured the behavior of humans in a task formally homologous to the task for rats, varying two of the three parameters previously shown to affect performance in rats. Signal quality was manipulated by varying the increment in the intensity of a lamp. Trial rate was varied among values of 4, 7, and 10 trials/min. Accuracy of signal detection was quantified by the proportion of correct detections of the signal (P(hit)) and the proportion of false alarms (P(fa), i.e. incorrect responses on non-signal trials). As with rats, P(hit) in humans increased with increasing signal intensity whereas P(fa) did not. Like rats, humans were sensitive to the trial rate, though the change in behavior depended on the sex of the subject. These data show that visual signal detection behavior in rats and humans is controlled similarly by two important parameters, and suggest that this task assesses similar processes of sustained attention in the two species.

AN - 73608737; 12953855 AB - The geologic storage (GS) of carbon dioxide (CO2) is emerging as an important tool for managing carbon. While this Journal recently published an excellent review of GS technology (Bruant, R. G.; Guswa, A. J.; Celia, M. A.; Peters, C. A. Environ. Sci. Technol. 2002, 36, 240A-245A), few studies have explored the regulatory environment for GS or have compared it with current underground injection experience. We review the risks and regulatory history of deep underground injection on the U.S. mainland and surrounding continental shelf. Our treatment is selective, focusing on the technical and regulatory aspects that are most likely to be important in assessing and managing the risks of GS. We also describe current underground injection activities and explore how these are now regulated.

Previous studies have associated Zn super(2+) levels in PM with health effects in exposed populations and have shown proinflammatory properties of Zn super(2+) exposure in vivo and in vitro. In the present study, we studied the mechanisms of epidermal growth factor receptor (EGFR) dimerization, phosphorylation, and kinase activity in A431 cells treated with Zn super(2+). EGF, but not Zn super(2+), induced dimerization of EGFR in A431 cells and membrane extracts. Like EGF, Zn super(2+) induced phosphorylation of EGFR at tyrosines 845, 1068, and 1173. However, unlike EGF, Zn super(2+) failed to induce detectable dimerization of EGFR. The EGFR kinase inhibitor PD153035 ablated all phosphorylation induced by EGF but none caused by Zn super(2+). PD153035 abolished EGF-induced phosphorylation of the EGFR substrate Cbl, but had no effect on levels of phospho-Cbl caused by Zn super(2+). Inhibition of EGFR kinase activity did, however, blunt Zn super(2+)-induced phosphorylation of ERK. Exposure to Zn super(2+), but not EGF, induced phosphorylation of the activating site of c-Src (tyrosine 416), and Zn super(2+)-induced phosphorylation of EGFR at tyrosines 845 and 1068 was blocked by the c-Src kinase activity inhibitor PP2. In summary, Zn super(2+) ions induce EGFR phosphorylation in a manner dependent on c-Src but not on EGFR dimerization or EGFR kinase activation, suggesting that Zn super(2+) induces EGFR transactivation by c-Src.

The results indicate that the remaining air plumes from the disaster site were comprised of many pollutants and classes and represent a complex mixture of biogenic (wood-smoke) and anthropogenic sources. This mixture includes compounds that are typically associated with fossil fuel emissions and their combustion products. The molecular markers for these emissions include the high molecular weight PAHs, the n-alkanes, a Carbon Preference Index similar to 1 (odd carbon:even carbon similar to 1), as well as pristane and phytane as specific markers for fuel oil degradation. These results are not unexpected considering the large number of diesel generators and outsized vehicles used in the removal phases. The resulting air plume would also include emissions of burning and remnant materials from the WTC site. Only a small number of molecular markers for these emissions have been identified such as retene and 1,4a-dimethyl-7-(methylethyl)-1,2,3,4,9,10,10a,4a-octahydrophenant hrene that are typically biogenic in origin. In addition, the compound 1,3-diphenylpropane-[1',1'-(1,3-propanediyl)bis-benzene] was observed, and to our knowledge, this species has not previously been reported from ambient sampling. It has been associated with polystyrene and other plastics, which are in abundance at the WTC site. These emissions lasted for at least 3 weeks (September 26-October 21, 2001) after the initial destruction of the WTC.

Possible explanations for the patterns in autotroph abundances were explored through examination of their correlations with the physicochemical characteristics of the water column. Study sites were established in each of three zones in the estuary defined by temperature and salinity and were sampled monthly June through September 1998 and in July 1999.Z. marina and macroalgal cover andZ. marina shoot density were measured in 0.25-m super(2) plots at each site. After cover estimates and shoot counts were made, material was harvested for determination ofZ. marina and macroalgal biomass. Water column variables were measured from stations near each study site and composited on a depth-averaged, monthly basis for each zone. BothZ. marina and green macroalgal abundance differed between sites, over the summer in 1998, and between years. Seasonal patterns were most obvious forZ. marina at the site closest to the ocean while the pattern in macroalgal abundance suggested a bloom moving up river as summer progressed. The physicochemical characteristics of the zones differed with the season and could be related to the patterns inZ. marina and macroalgal abundance. In particular, salinity was positively correlated withZ. marina abundance, while abundance of both autotrophs was related to light availability.Z. marina biomass ranged 19-109 g dry weight m super(-2); green macroalgae biomass ranged 5-234 g dry weight m super(-2). The biomass of the green macroalgae at several sites and dates equaled or exceed that of theZ. marina suggesting the potential for nuisance algal blooms does exist in Yaquina Bay.

AN - 75705581; 14506632 AB - We report on a deposition of oxalate crystals on ferruginous bodies after occupational exposure to asbestos demonstrated in 3 patients. We investigated the mechanism and possible significance of this deposition by testing the hypothesis that oxalate generated through nonenzymatic oxidation of ascorbate by asbestos-associated iron accounts for the deposition of the crystal on a ferruginous body. Crocidolite asbestos (1000 microg/mL) was incubated with 500 micromol H(2)O(2) and 500 micromol ascorbate for 24 hours at 22 degrees C. The dependence of oxalate generation on iron-catalyzed oxidant production was tested with the both the metal chelator deferoxamine and the radical scavenger dimethylthiourea. Incubation of crocidolite, H(2)O(2), and ascorbate in vitro generated approximately 42 nmol of oxalate in 24 hours. Oxalate generation was diminished significantly by the inclusion of either deferoxamine or dimethylthiourea in the reaction mixture. Incubation of asbestos bodies and uncoated fibers isolated from human lung with 500 micromol H(2)O(2) and 500 micromol ascorbate for 24 hours at 22 degrees C resulted in the generation of numerous oxalate crystals. We conclude that iron-catalyzed production of oxalate from ascorbate can account for the deposition of this crystal on ferruginous bodies.

AN - 73655115; 12971695 AB - Parents in all countries want and deserve safe and healthy environments for their children. Children in all countries need, as part of normal growth and development, regular and frequent opportunities to interact with their environments as they learn to crawl, run, climb, swim, and explore. Environmental scientists and regulators recognize that environmental hazards are not contained by international borders. This is of special concern for children, because they are intrinsically at greater risk, compared to adults. They have different opportunities for exposure, greater response to certain toxicants, and less empowerment to alter their environments. There is a growing awareness that adverse health effects in children can adversely affect a country's future productivity and well-being. Multiple government agencies, NGOs, and advocates are mobilizing to address these concerns. A sustained concerted effort will be needed to afford equitable and effective environmental health protection to the world's children, present and future.

AN - 73642232; 12971694 AB - The success of regional networks to provide incentives and mechanisms for sharing information is illustrated through the North American Regional Action Plan on DDT (NARAP). This NARAP was designed to reduce human and environmental exposure to DDT and its metabolites in North America through cooperative efforts. The increasing role of environmental concerns in the planning and design of Mexico's DDT phase-out program motivated the Mexican Ministry of Health to undertake an alternative program for malaria control maximizing community participation without negatively affecting human and ecosystem health. This program relies on: 1) elimination of parasites in people, 2) improvement of personal and household hygiene, and 3) use of environmental management practices to eliminate mosquito breeding sites. This new strategy resulted in the elimination of DDT for malaria control in Mexico in the year 2000. While malaria and its corresponding vectors show considerable variability within a single country and certainly around the globe, the case example of Mexico provides a methodology for developing alternatives to DDT.

AN - 73533006; 12902193 AB - Chronic high-dose inhalation of carbon black (CB) can produce carcinomas in rat lungs. The mechanisms underlying this response are uncertain. It has been hypothesized that chronic inflammation and cell proliferation may play a role in the development of tumors after high dose, long-term contact of the particles with lung epithelial cells. In this investigation, we analyzed the formation of a known mutagenic lesion [8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dG)] in the lung DNA of rats following subchronic inhalation of CB (Printex-90 and Sterling V). Briefly, female Fischer 344 rats were exposed for 6 h/day, 5 days/week for 13 weeks to 1, 7, and 50 mg/m(3) of Printex-90 (16 nm; specific surface area 300 m(2)/g) and to 50 mg/m(3) of Sterling V CB (70 nm; surface area of 37 m(2)/g). The exposure concentration of Sterling V was selected to be equivalent in terms of retained mass in the lung to the high dose of Printex-90 at the end of exposure. However, in terms of retained particle surface area, the retained lung dose of Sterling V was equivalent to the mid-dose of Printex 90. This design allows comparison of results on the basis of retained particle mass as well as retained particle surface area between the two CB particles. The formation of 8-oxo-dG in the lung DNA was assessed using a reverse phase HPLC system coupled with UV and electrochemical (EC) detection. After 13 weeks of exposure, measurements were made on lung samples obtained at the end of the exposure and a 44-week recovery period in clean air. Lung burdens of CB were determined at both time points as well as differential cell populations from bronchoalveolar lavage fluid (BAL). The results indicate that lung particle overload was achieved after exposure to 7 and 50 mg/m(3) (Printex-90) and 50 mg/m3 (Sterling V) but not at 1 mg/m(3) (Printex-90). Consistent with these results, a significant increase (P < 0.05) in 8-oxo-dG induction was observed following 13 weeks of exposure to 50 mg/m(3) Printex-90 and at 7 and 50 mg/m(3) after the 44-week recovery period. Interestingly, no increase in 8-oxo-dG was observed for Sterling V CB at either time point despite lung particle overload. Although the retained mass dose of Sterling V at the end of exposure was even higher than for Printex 90 (50 mg/m(3) exposure group) (approximately 7.6 vs 4.8 mg), the surface area of the retained Sterling V was similar to that of the retained Printex 90 of the mid-dose exposure (7 mg/m(3)) (approximately 0.2 m(2) in both groups). Since both Sterling V (50 mg/m(3)) and Printex 90 (7 mg/m(3)) did not induce significant increases in 8-oxo-dG in the lung at the end of the 13-week exposure, this finding indicates that a retained large particle mass is not always correlated with similar adverse effects but that particle surface area is a better dose parameter. The lower effect per unit mass dose seen with Sterling V is consistent with earlier studies showing that particle surface area of low toxicity particles is a more appropriate dosemetric for induction of inflammation in the lungs than particle mass (Oberdörster et al., 1994, 2001; Brown et al. 2001; Donaldson et al., 2002). An increase (p < 0.05) in lung lavage neutrophils was observed at 7 mg/m(3) (Printex-90) and 50 mg/m(3) (Printex-90 and Sterling V) at the 13-week exposure period and again at 50 mg/m(3) (Printex-90 and Sterling V, 44-week recovery period). Our current findings suggest that prolonged, high-dose exposure to CB can promote oxidative DNA damage that is consistent with the hypothesis that inflammatory cell-derived oxidants may play a role in the pathogenesis of rat lung tumors following long-term high-dose exposure to CB in rats.

AN - 73518933; 12877875 AB - Accounting of carbon stocks in woody vegetation for greenhouse purposes requires definition of medium term trends with accurate error assessment. Tree and shrub cover was sampled through time at randomly located sites over a large area of central Queensland, Australia using aerial photography from 1945 to 1999. Calibration models developed from field data for the same land types as those represented within the study area allowed for the extrapolation of overstorey and understorey cover, basal area and biomass values and these were modelled as trends over the latter half of the 20th century. These structural attributes have declined over the region because of land clearing with values for biomass changing from a mean of 58.0(+/-1.2)t/ha in 1953 to 41.1(+/-1.0)t/ha in 1991. The biomass of Acacia on clay and Eucalypt on texture contrast soils land types has declined most dramatically. Within uncleared vegetation there was an overall trend of increase from 56.1(+/-1.2)t/ha in 1951 to 67.6(+/-1.3)t/ha in 1995. The increase in structural attributes within uncleared vegetation was most pronounced for the Eucalypt on texture contrast soils and Eucalypt on clay land types. It was demonstrated that the sites sampled were representative of their land types and that spatial bias of the photography, undetected tree-killing, sampling error, inherent variability of structural attributes and measurement error should not have impacted greatly on bias or precision of trend estimates for well-sampled land types. Certainly the errors are not likely to be substantial for trends averaged over all land types and they provide an accurate assessment of the magnitude and direction of change. The technique presented here would appear to be a robust means of accounting for the above-ground woody component of woodlands and open forests and will also contribute to a broader understanding of savanna dynamics.

AN - 73498436; 12877874 AB - Features of the land management history over a 125,755 km(2) area of central Queensland, Australia were determined from a variety of sources. A random sample of 205 site locations provided the basis for determining trends in land use. Trends in vegetation clearing were determined using sequential aerial photography for the sample sites, revealing a steady rate averaging nearly 1% of the region per annum over 41 years. This measure of sustained clearing over a large region is higher than recently published clearing rates from South America. Land types have been selectively cleared with over 90% of the Acacia on clay land type having been cleared. A land-holder questionnaire pertaining to the random sites yielded a response rate of 71% and provided information on vegetation clearing, ploughing, tree killing (ring-barking or tree poisoning), and fire frequency, season and intensity. The land-holder responses were compared with independent data sources where possible and revealed no mis-information. However, land-holders may have been marginally less likely to respond if the sample area had been cleared, although this effect was not statistically significant. Ploughing and tree killing are variable depending on land type, but the former has affected about 40% of the Acacia on clay land type, effectively eliminating options for natural regrowth. The proportion of decade-site combinations that were reported as having no fires increased from 22% in the 1950s to an average of 42% for subsequent decades, although the reporting of more than one fire per decade has been relatively constant through the study period. The reporting of at least one fire per decade varies from 46% for the Acacia on sand land type to 77% for the Eucalypt on sand land type for decade-site combinations. Fires are more intense when associated with clearing than in uncleared vegetation, but the proportion of cool and hot fires is relatively constant between land types in uncleared vegetation. Nearly all fires reported were either in spring or summer and this seasonally restricted regime is probably at variance with Aboriginal fire regimes. This study describes the rapid transformation of central Queensland. This has yielded substantially increased agricultural production but may also result in a range of negative impacts and these are discussed.

I: maternal and prenatal evaluations. AN - 73481855; 12773773 AB - The maternal and developmental toxicities of perfluorooctane sulfonate (PFOS, C8F17SO3-) were evaluated in the rat and mouse. PFOS is an environmentally persistent compound used as a surfactant and occurs as a degradation product of both perfluorooctane sulfonyl fluoride and substituted perfluorooctane sulfonamido components found in many commercial and consumer applications. Pregnant Sprague-Dawley rats were given 1, 2, 3, 5, or 10 mg/kg PFOS daily by gavage from gestational day (GD) 2 to GD 20; CD-1 mice were similarly treated with 1, 5, 10, 15, and 20 mg/kg PFOS from GD 1 to GD 17. Controls received 0.5% Tween-20 vehicle (1 ml/kg for rats and 10 ml/kg for mice). Maternal weight gain, food and water consumption, and serum chemistry were monitored. Rats were euthanized on GD 21 and mice on GD 18. PFOS levels in maternal serum and in maternal and fetal livers were determined. Maternal weight gains in both species were suppressed by PFOS in a dose-dependent manner, likely attributed to reduced food and water intake. Serum PFOS levels increased with dosage, and liver levels were approximately fourfold higher than serum. Serum thyroxine (T4) and triiodothyronine (T3) in the PFOS-treated rat dams were significantly reduced as early as one week after chemical exposure, although no feedback response of thyroid-stimulating hormone (TSH) was observed. A similar pattern of reduction in T4 was also seen in the pregnant mice. Maternal serum triglycerides were significantly reduced, particularly in the high-dose groups, although cholesterol levels were not affected. In the mouse dams, PFOS produced a marked enlargement of the liver at 10 mg/kg and higher dosages. In the rat fetuses, PFOS was detected in the liver but at levels nearly half of those in the maternal counterparts, regardless of administered doses. In both rodent species, PFOS did not alter the numbers of implantations or live fetuses at term, although small deficits in fetal weight were noted in the rat. A host of birth defects, including cleft palate, anasarca, ventricular septal defect, and enlargement of the right atrium, were seen in both rats and mice, primarily in the 10 and 20 mg/kg dosage groups, respectively. Our results demonstrate both maternal and developmental toxicity of PFOS in the rat and mouse.

Efforts were made to draw yield surfaces in the stress space. To pay special attention to anisotropic yielding due to solely the shear process, p' was kept constant to avoid yielding caused by the change of p'.sigma (sub 1) - direction from the vertical in the shear process was fixed to be from 0 degrees to 90 degrees at 11.25 degrees interval. It was found that the sand starts yielding progressively from the strain level as small as 0.002%. The simple way of interpreting elastic behaviour below the large-scale yield surface, which is determined to be at much larger strain level, can not explain such behaviour. Two subyield surfaces, Y (sub 1) and Y (sub 2) , were identified inside the large-scale yield surface, Y (sub 3) . It is shown that these surfaces can explain nonlinearity and degradation of stiffness moduli. Anisotropy and mobility of the subyield surfaces were also studied in the p'-constant shear plane. When the initial stress state was at the origin of the shear plane (isotropic stress state), the shape of the yield surface was approximately circular with the center shifted toward compression in the vertical direction. Anisotropy increased with the progress of shearing. Y (sub 1) and Y (sub 2) surfaces were mobile and moved with the current stress point in the p'-constant shear plane, though Y (sub 3) surface was comparatively immobile. The shapes of yield surfaces also changed with the movement of current stress point.

Many of these absorption bands are relatively broad and overlapping; however, spectral analysis methods, including continuum removal and derivative analysis, permit most of the minerals to be distinguished. Key spectral differences between the minerals are illustrated in a series of plots showing major absorption band centers and other spectral feature positions. Because secondary iron minerals are sensitive indicators of pH, Eh, relative humidity, and other environmental conditions, spectral mapping of mineral distributions promises to have important application to mine waste remediation studies.

Projected increases in carbon dioxide and temperature over the next 50 years exceed the conditions under which coral reefs have flourished over the past half-million years. However, reefs will change rather than disappear entirely, with some species already showing far greater tolerance to climate change and coral bleaching than others. International integration of management strategies that support reef resilience need to be vigorously implemented, and complemented by strong policy decisions to reduce the rate of global warming.

However, a number of simplifying assumptions can be used to develop and validate (Q)CARs to predict the toxicity of metals: The ionic form is the most active form of a metal; the bioactivity of a dissolved metal is correlated with its free ion concentration or activity; most metals exist in biological systems as cations, and differences in metal toxicity result from differences in metal ion binding to biological molecules (ligand-binding). In summary, it appears that certain useful correlations can be made between several physical and chemical properties of ions (mostly cations) and toxicity of metals. This review provides a historical perspective of studies that have reported correlations between physical and chemical properties of cations and toxicity to mammalian and nonmammalian species using in vitro and in vivo assays. To prepare this review, approximately 100 contributions dating from 1839 to 2003 were evaluated and the relationships between about 20 physical and chemical properties of cations and their potential to produce toxic effects were examined.

Many structure-activity relationship models have been developed to predict chemical binding to the estrogen receptor as an indication of potential estrogenicity. Models based on either two-dimensional or three-dimensional molecular descriptions that have been used to predict potential for binding to the estrogen receptor are the subject of the current review. The utility of such approaches to predict binding potential of diverse chemical structures in large chemical inventories, with potential application in a tiered risk assessment scheme, is discussed.

As the demand for different types of regulatory testing increases and the cost of experimental testing escalates, there is a need to evaluate the use of QSARs and provide some guidance to avoid their misuse, especially as QSARs are being considered for regulatory purposes. This paper provides some guidelines that will promote the proper development and use of QSARs. While this paper uses examples of QSARs to predict toxicity, the proposed guidelines are applicable to QSARs used to predict physical or chemical properties, environmental fate, ecological effects and health effects.

Overall progress has been hampered by the sparseness of good quality experimental data. A number of researchers have used the same data set to develop QSARs for predicting percutaneous absorption rates, a fact that makes it difficult, at this time, to recommend one or two QSARs for predicting percutaneous absorption rates. Identification of chemicals within domains of large chemical universes that should be tested to improve QSARs and the subsequent development of experimental percutaneous absorption rates for those chemicals will facilitate the development of more robust QSARs for predicting percutaneous absorption rates.

These models differ not only in the processes they address but also in the way a given process is described. Processes described by these models include chemical diffusion through the gills interlamellar water, epithelium, and lamellar blood plasma; advective chemical transport to and from the gill by ventilation and perfusion, respectively; and internal chemical deposition by thermodynamic partitioning to lipid and other organic phases. This article reviews the construction and associated assumptions of 10 of the most widely cited fish bioconcentration models. These models are then compared with respect to their ability to predict observed uptake and elimination rates using a common database for those model parameters that they have in common. Statistical analyses of observed and predicted exchange rates reveal that rates predicted by these models can be calibrated almost equally well to observed data. This fact is independent of how well any given model is able to predict observed exchange rates without calibration. The importance of gill exchange models and how they might by improved are also discussed.

This work studies a literature procedure as a possible general approach to many pesticides and potentially other analytes that are considered to be liquid chromatographic (LC) candidates, rather than gas chromatographic (GC) ones. The analysis of the sewage effluent of a major southwestern U.S. city serves as an example of the application of the methodology to a real sample. Recovery studies were also conducted to validate the proposed extraction step. A gradient elution program was followed for the high-performance LC (HPLC) leading to a general approach for acidics. Confirmation of identity was by electron ionization-GC-mass spectrometry (MS) after conversion of the acids to the methyl ester (or other appropriate methylation) by means of trimethylsilyldiazomethane. The 3,4-dichlorophenoxyacetic acid is used as an internal standard to monitor the reaction, and polychlorobiphenyl #19 is used for the quantitation internal standard. Although others have reported similar analyses of acids, conversion to the methyl ester is by means of diazomethane itself, rather than by the more convenient and safe trimethylsilyldiazomethane. Thus, the present paper supports the use of trimethylsilyldiazomethane with all of these acids (trimethylsilyldiazomethane has been used in environmental work with some phenoxyacetic acid herbicides) and further supports the usefulness of this reagent as a potential replacement for diazomethane. The HPLC approach here could also serve as the separation basis for an LC-MS solution for confirmation of identity, as well as quantitation.

The amount of residual EO remaining in a device depends partly on the type and size of polymeric material. A major concern is the amount of residue that may be available in the body. With the use of the method described by AAMI for headspace analysis of EO residues, different polymers and medical devices subjected to different numbers of sterilization cycles were examined. Next, the effect of various extraction conditions and extraction solutions on these polymers and medical devices was evaluated. The results showed different polymers desorb EO differently. One polyurethane (PU 75D) had much higher EO residue than a different polyurethane (PU 80A). Repeated extraction of the PU 75D was necessary to quantify total EO residue levels. Different extraction solutions influence the amount and reproducibility of EO detected, whereas multiple resterilizations showed no difference in amount of residual EO. Bioavailability of EO was estimated by extracting the devices and polymers in water. Comparison of total EO residues to EO that was bioavailable showed no difference for some polymers and devices, while others had an almost eightfold difference.

With the ever-increasing production of new chemicals, and the need to optimize resources to assess thousands of existing chemicals in commerce, regulatory agencies have turned to QSARs as essential tools to help prioritize tiered risk assessments when empirical data are not available to evaluate toxicological effects. Progress in designing scientifically credible QSARs is intimately associated with the development of empirically derived databases of well-defined and quantified toxicity endpoints, which are based on a strategic evaluation of diverse sets of chemical structures, modes of toxic action, and species. This review provides a brief overview of four databases created for the purpose of developing QSARs for estimating toxicity of chemicals to aquatic organisms. The evolution of QSARs based initially on general chemical classification schemes, to models founded on modes of toxic action that range from nonspecific partitioning into hydrophobic cellular membranes to receptor-mediated mechanisms is summarized. Finally, an overview of expert systems that integrate chemical-specific mode of action classification and associated QSAR selection for estimating potential toxicological effects of organic chemicals is presented.

At times, it is useful to conduct screening risk assessments to assist in prioritizing or ranking chemicals on the basis of potential hazard and exposure assessment parameters. Ranking of large chemical inventories can provide evidence for focusing research and/or cleanup efforts on specific chemicals of concern. Because of financial and time constraints, data gaps exist, and the risk assessor is left with decisions on which models to use to estimate the parameter of concern. In this review, several methods are presented for using quantitative structure- activity relationships (QSARs) in conducting hazard screening or screening-level risk assessments. The ranking methods described include those related to current regulatory issues associated with chemical inventories from Canada, Europe, and the United States and an example of a screening-level risk assessment conducted on chemicals associated with a watershed in the midwest region of the United States.

This article describes how the park establishment process turned negative local opinion positive. The basis for success was a shift of focus from restrictions inside the boundaries of the national park to opportunities outside. This 'inside-out' process implies a new approach to area protection and local community participation in Sweden. This is in line with the contemporary Swedish nature conservation strategy based on the principle of sustainability, which takes account of both ecological and socioeconomic development in a district.

The transfer of electrons to organochlorines via reductive dehalogenation reactions plays an important role in hydrogen dynamics in impacted systems. We studied the flux of aqueous hydrogen concentrations in methanogenic sediment microcosms prior to and during reductive dehalogenation of a variety of substituted chlorophenols (CP) and tetrachloroethene (perchloroethylene, PCE). Mean hydrogen concentrations during reductive dehalogenation of 2,4-CP, 2,3,4-CP, and PCP were 3.6 nM, 4.1 nM, and 0.34 nM, respectively. Sediment microcosms that were not dosed with chlorophenols yet were actively methanogenic maintained a significantly higher mean hydrogen concentration of 9.8 nM. During active PCE dehalogenation, sediment microcosms maintained a mean hydrogen concentration of 0.82 nM. These data indicate that during limiting hydrogen production, the threshold ecosystem hydrogen concentration is controlled by microbial populations that couple hydrogen oxidation to thermodynamically favorable electron accepting reactions, including reductive dehalogenation of chloroaromatic and chloroaliphatic compounds. We also present revised estimates for the Gibbs free energy available from the reductive dehalogenation of a variety of substituted chlorophenols based on recently published values of vapor pressure, solubility, and pK sub(a) for these compounds.

In contrast, biological invasions are occurring daily in the US and have significant impacts on human health, agriculture, infrastructure, and the environment, yet they receive far less attention and fewer resources. Scientists and the US government must work together to implement a comprehensive approach to biosecurity that addresses not only bioterrorism, but also the more common incursions of invasive alien species. This approach should also address the potential for the deliberate use of invasive alien species as agents of bioterrorism. To achieve these goals, it will be necessary for the relevant government institutions to acknowledge and include prevention, early detection, and rapid response to species incursions as central mission themes. In addition, the scientific community, industry, and the public must work together to ensure that the necessary technology and information systems are readily available.

We analyzed additional adipose and serum samples collected in the late 1990s from San Francisco Bay Area women participating in a breast cancer study and in a reproductive study, respectively. Adipose samples (n = 32) were analyzed by low-resolution mass spectrometry in negative-ion chemical ionization mode, whereas serum samples (n = 50) were analyzed by dual-column gas chromatography with electron capture detection. The results confirmed our earlier findings. Concentrations of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) in contemporary California women ranged between 5 and 510 ng/g lipid, with a median (16.5 ng/g lipid) 3-10 times higher than those reported from Europe. In contrast, PBDEs were not measurable in any of 420 archived serum samples collected in the 1960s from San Francisco Bay Area women participating in a study of child development. BDE-47 concentrations did not increase with age or with concentrations of a polychlorinated biphenyl (PCB-153), suggesting other routes of exposure in addition to diet. Rising body burdens of endocrine-disrupting chemicals such as PBDEs may pose a potential public health threat.

A complicating factor receiving increasing attention is that arsenic is biomethylated to form various metabolites. Eleven different arsenicals were studied for in vitro genotoxicity to supercoiled DNA (pBR 322 and phi X174). Five arsenicals showed various degrees of positivity-monomethylarsonous acid, dimethylarsinous acid, monomethylarsine, dimethylarsine, and trimethylarsine. Supercoiled DNA, blotted on nitrocellulose filter paper, was exposed to gaseous arsines by suspending the filter paper above aqueous reaction mixtures of sodium borohydride and an appropriate arsenical. All three methylated arsines damaged DNA; inorganic arsine did not. Arsines were generated in situ in reaction mixtures containing DNA by reaction of sodium borohydride with arsenite, monomethylarsonous acid, dimethylarsinous acid, and trimethylarsine oxide, at pH 8.0. Both dimethylarsine and trimethylarsine (generated from 200 mu M dimethylarsinous acid and trimethylarsine oxide, respectively) damaged DNA in less than 30 min. Under certain conditions, the two most potent genotoxic arsines, trimethylarsine and dimethylarsine, are about 100 times more potent than dimethylarsinous acid (the most potent genotoxic arsenical previously known). There was no evidence to suggest that anything other than the arsines caused the DNA damage. Possible models for the biological production of arsines were examined. The coenzymes, NADH and NADPH, are biological hydride donors. When NADH or NADPH (5 mM) were incubated with dimethylarsinous acid (0-2 mM) for 2 h, DNA damage was increased by at least 10-fold. A possible explanation for this result is that these compounds react with dimethylarsinous acid to generate dimethylarsine. DNA was incubated with a dithiol compound, dithioerythritol (5 mM), and trimethylarsine oxide (0.5 mM) for 2 h, and the reduction of trimethylarsine oxide to trimethylarsine resulted in DNA damage.

To understand how this species might respond to changing environments, we examine the relationship between two hydrologic variables and growth of three stands of P. elliottii var. densa occurring along a hydrologic gradient using tree-ring records. The two variables were a short-term indicator of water status, precipitation minus potential evapotranspiration (P-PET), and a long-term indicator of water status, runoff (R). Growth at all sites was positively correlated to current growing season P-PET and R, and strongly, negatively correlated with previous winter R. The positive correlation with spring R was greater in the site with the deepest water table than in sites with shallower water tables. We discuss the potential for root dynamics to explain the relationships between growth and R.

Two recycling strategies adopted before and after 1998 were compared because of changes in the management of recycling funds, the performance of sanitation workers, and the auditing system. The overall volumes of all recycled materials and the amount of selected items recycled such as disposed PET bottles were compared. In the five years from 1997 to 2002, the materials collected for recycle by sanitation teams increased from 106.2 thousand tons per year to 878.3 thousand tons. This meant that the nationwide recycling rate had increased from 2.56% to 15.48%, respectively. During the periods of 1988-1997, the average amount of solid waste in Taiwan increased 4.5% annually. On the other hand, from 1998 to 2002, the average amount of solid waste decreased 5.9% annually. The amount of various specific recycled materials increased from 1.71 times to 10.77 times in five years. The resource recycling system based on monetary incentives incorporating a command-and-control strategy can raise the recycling rate significantly.

The influences of alkalinity, Cl super(-), and different concentrations of ethylene diamine tetraacetic acid (EDTA) and fulvic acid (FA) on the labile concentration and toxicity of Cu were investigated in reconstituted water and natural water. The results showed that Cl super(-) and alkalinity did not affect labile Cu concentration, but decreased the toxicity of Cu to S. obliquus in the Cu concentration range observed in fresh water. The influences of alkalinity and Cl super(-) could be modeled if Cu-carbonate complexes and Cu-chloride complexes were considered as non-toxic species. Organic complexes of Cu with EDTA and FA did not contribute either to the labile concentration of Cu or to the toxicity of Cu on S. oblignus. The growth inhibition of Cu on S. oblignus in natural water could be predicted by using the bioavailable concentration of Cu, or [Cu], which could be calculated from the labile Cu concentration using the DAM-DPASV method and the concentrations of Cu-carbonate and Cu-chloride complexes obtained from the MINTEQ A2 model.

In this effort, based on continuity of mass flux, we derive a mass flux boundary condition of the third type in terms of physically based mass transfer rate coefficients, describing the resistance to mass inflow of the soil-air interface, and obtain one-dimensional analytical solutions for transport and degradation of volatile organic compounds in semi-infinite structured soils under steady, unsaturated flow conditions. The advective- dispersive mass balance formulation allows for mobile-immobile liquid phase and vapor diffusive mass transfer, with linear equilibrium adsorption and liquid- vapor phase partitioning in the dynamic and stagnant soil regions. The mass transfer rate coefficients of volatile organic chemicals across the soil-air interface are expressed in terms of solute properties and hydrodynamic characteristics of resistive soil and air-boundary layers. The solutions estimate solute vapor flux from soil surface and describe mobile-phase solute concentration as a function of depth in the soil and time. In particular, solutions were derived for: (1) zero-initial concentration in the soil profile subject to a continuous and pulsed source at the soil surface; and (2) depletion from the soil following an initially contaminated soil profile. Sensitivity analysis with respect to different dimensionless parameters is conducted and the effect on solute concentration and vapor flux of such parameters as volatilization mass transfer velocity relative to infiltration, soil Peclet number, biochemical decay, and diffusive mass transfer into the immobile phase, is plotted and the results are discussed. The mass transfer rate coefficients and the analytical solutions are applied to simulate transport of an example volatile organic compound in an aggregated soil. The simulated results indicate that macropore-aggregate vapor phase diffusion may profoundly impact transport of volatile compounds in aggregated soils.

The water quality target of the TMDL was determined by the state to be the chlorophyll-a concentrations in the estuary. EPA Region 4 partnered with the State of North Carolina to provide technical assistance and guidance for nutrient TMDL development in the Neuse River Estuary. The goal was the development of hydrodynamic and water quality models that are sufficient to simulate the complex circulation and water quality kinetics within the system, including salinity and temperature stratification, wind driven seiching, dissolved oxygen stratification, and longitudinal and lateral variations in nutrient and chlorophyll-a concentrations. A three-dimensional, hydrodynamic, and water quality model was developed in the estuary from Maw Point at the Pamlico Sound boundary, to upstream at Streets Ferry Bridge above New Bern, North Carolina. The complex three-dimensional hydrodynamics of the Neuse estuary were modeled using the Environmental Fluid Dynamics Code (EFDC). EFDC was applied with water surface elevation forcing at the downstream boundary, freshwater inflows at the upstream boundaries, and wind over the water surface of the modeled domain. Water surface elevation, flows, currents, salinity, and temperature were simulated using EFDC. The U.S. EPA Water Quality Analysis Simulation Program (WASP6) was applied for the water quality portion of the model. The eutrophication model of WASP was used to simulate the complex nutrient transport and cycling in the estuary. The purpose of the water quality model is to predict a response in chlorophyll-a and dissolved oxygen concentrations as a function of nutrient loadings and transport throughout the Neuse River Estuary. The model was used to evaluate various loading scenarios and the impact on water quality within the "use support" areas within the 303(d) listed segments. The hydrodynamic and water quality models were calibrated for 1998 and confirmed for 1999 and 2000. A comparison of the model simulations with the extensive dataset shows that the models are accurately simulating the longitudinal/seasonal distribution of the hydrodynamics, mass transport, and water quality. The water quality model was used to evaluate TMDL scenarios.

AN - 73565768; 12927729 AB - Factors influencing dense non-aqueous phase liquid (DNAPL) removal by concurrent injection of cosolvent and air were evaluated using micromodels and visualization techniques. Cosolvent (ethanol/water) was injected simultaneously with air into glass micromodels containing residual perchloroethylene (PCE). Impacts of the air flow rates and PCE solubility in the remedial fluid on PCE removal processes were examined. Although two major processes, immiscible displacement and dissolution, may contribute PCE removal from porous media during cosolvent-air (CA) flooding, PCE displacement occurred only in the initial flooding period and was independent of the air flow rate and ethanol content. However, faster airflow through the porous medium improved remedial fluid distribution and dynamics and resulted in enhanced dissolution of the DNAPL.

AN - 73460214; 12851231 AB - The authors examined influences of asthma and household environment (passive smoking, use of a gas stove, and having a dog or cat) on five measures of spirometric lung function among 8- to 16-year-old subjects, as measured cross-sectionally in the Third National Health and Nutrition Examination Survey (NHANES III) (1988-1994). In regression models, independent variables included asthma status, household environmental factors, age, and anthropometric measurements. Regression analyses were weighted by the NHANES III examination sample weighting factor, and results were adjusted for clustering in the sampling design. There were distinct sex differences in the results. In girls, lung function was lowest among active asthmatics taking prescription respiratory medicine, whereas lung function in other active and inactive asthmatics did not differ greatly from that in nonasthmatics. In boys, however, all groups of asthmatics had substantially lower lung function than nonasthmatics. Differences in lung function between active asthmatics and nonasthmatics were stable with increasing age. However, the lung function of inactive asthmatic girls and boys returned to and diverged from nonasthmatics' levels, respectively. In asthmatic girls, passive smoking was associated with reduced lung function; having a dog or cat was associated with increased lung function; and gas stove use was associated with reduced lung function among subjects not taking prescription respiratory medicine.

The microbial measures included super(3)H-L-leucine incorporation, ectoenzyme activity (aminopeptidase, alpha -D-glucosidase, beta -D-glucosidase) and bacterial abundance. Bacterioplankton abundance ranged from 1.8 to 15.3 x 10 super(9) l super(-1) (average: 6.2 x 10 super(6)); highest abundances occurred during summer months, particularly in the upper estuary. Bacterial secondary production ranged from 20 to 273 mu g C l super(-1) d super(-1) (average 115), aminopeptidase activities ranged from 34 to 356 nmol l super(-1) d super(-1) (average 165), alpha -D-glucosidase ranged from 0.4 to 61 nmol l super(-1) d super(-1) (average: 8.3), and beta -D-glucosidase ranged from 1.4 to 53.1 nmol l super(-1) d super(-1) (average: 10.5). Bacterioplankton exhibited strong seasonality, suggesting that temperature was an important driver of the observed variability. When normalized for bacterial biomass, metabolic rates exhibited a striking inter-annual pattern with lower rates during summer 2000 than 2001. This pattern was consistent with freshwater flows, which were much lower during 2000 than 2001, consequently lowering nutrient and dissolved organic carbon (DOC) supply to the estuary. These results underscore the importance of riverine flux of materials to support bacterial metabolism and suggest that bacterioplankton were substrate-limited during the low flow period. The empirical relationships between bacterioplankton and phytoplankton variables were similar to those found in literature synthesis studies, with the notable exception that bacterial abundances and production were higher than predicted from chlorophyll a concentration. One explanation for this departure is that these relationships are drawn largely from cool temperate environments and warm subtropical systems are underrepresented in the literature.

AN - 73427610; 12834753 AB - Trihalomethanes (THMs) are disinfection by-products and suspected human carcinogens present in chlorinated drinking water. Previous studies have shown that many THMs induce sister chromatid exchanges and DNA strand breaks in human peripheral blood lymphocytes in vitro. Exposure to THMs occurs through oral, dermal, or inhalation routes, with the lung being a target of exposure by the latter route, although not a target for rodent carcinogenicity. Thus, to examine the genotoxicity of THMs in this tissue, we used the comet assay to examine the DNA damaging ability of five THMs in primary human lung epithelial cells. Cells were collected by scraping the large airways of four volunteers with a cytology brush and then passaging the cells no more than three times in order to have sufficient numbers for the experiments. Cells were exposed for 3h to 10, 100, or 1000 microM CHCl(3), CHCl(2)Br, CHClBr(2), or CHBr(3); CH(2)Cl(2) was also used as a model dihalomethane for comparison to the THMs. The compounds ranked as follows for DNA damaging ability: CHCl(2)Br>CHBr(3)>CHCl(3) approximately equal CH(2)Cl(2); CHClBr(2) was negative. Considerable inter-individual variation was observed. For example, CHCl(3) was genotoxic in only two subjects, and the interaction between dose and donor was highly significant (P<0.001). The same variation was observed for CHCl(2)Br, which was positive only in the two subjects in which CHCl(3) was negative. This variation was not due to the GSTT1-1 genotype of the subjects. Although two subjects were GSTT1-1(+), and two were GSTT1-1(-), no cultured cells with a GSTT1-1(+) genotype had detectable GSTT1-1 enzymatic activity nor did any frozen epithelial cells that had not been cultured. However, GSTT1-1 enzymatic activity was detected in fresh (neither frozen nor cultured) lung cells. These results show that freezing or culturing causes lung cells to lose GSTT1-1 activity and that factors other than GSTT1-1 activity play a role in the variable responses of these human cells to the genotoxicity of the halomethanes studied here.

AN - 73595724; 12931889 AB - This study was conducted to determine the extent of Pb absorption into young rats (Rattus norvegicus var. Sprague-Dawley) fed untreated Pb-contaminated soil or Pb-contaminated soil treated with two different sources of P and P + Mn oxide. Data were compared from an in vitro, physiologically based extraction test (PBET) with the animal data to support the validity of the in vitro test to assess bioavailable Pb from a treated Pb-contaminated soil. Soil with a total Pb concentration of 2290 mg kg(-1) was used. Rats were fed 19 different test diets for 21 consecutive days. The test diets represented 95 g AIN93G rat meal kg(-1) diet with varying proportions of silica sand or soil to provide low, medium, or high doses of Pb from either Pb acetate, treated, or untreated soil. Blood, liver, kidney, and bone Pb concentrations were examined. For all four tissues, Pb concentrations for the Pb acetate groups were significantly higher than concentrations for all the soil groups. In general, either triple superphosphate (TSP) or phosphate rock (PR) treatments resulted in significant reductions in tissue Pb concentrations compared with untreated soil. Blood and kidney Pb concentrations for the PR + Mn oxide group were significantly lower than those of the PR group at the low and high doses. Relative bioavailability of Pb, as measured in all tissues, was significantly reduced when comparing untreated with amended soil. Correlation between the in vitro and in vivo tests, based on bone and liver tissue, showed that the in vitro test is successful at predicting Pb bioavailability.

AN - 73585367; 12923556 AB - This paper tests factors thought to be important in explaining the choices people make in where they spend time. Three aggregate locations are analyzed: outdoors, indoors, and in-vehicles for two different sample groups: a year-long (longitudinal) sample of one individual and a cross-sectional sample of 169 individuals from the US Environmental Protection Agency's Consolidated Human Activity Database (CHAD). The cross-sectional sample consists of persons similar to the longitudinal subject in terms of age, work status, education, and residential type. The sample groups are remarkably similar in the time spent per day in the tested locations, although there are differences in participation rates: the percentage of days frequenting a particular location. Time spent outdoors exhibits the most relative variability of any location tested, with in-vehicle time being the next. The factors found to be most important in explaining daily time usage in both sample groups are: season of the year, season/temperature combinations, precipitation levels, and day-type (work/nonwork is the most distinct, but weekday/weekend is also significant). Season, season/temperature, and day-type are also important for explaining time spent indoors. None of the variables tested are consistent in explaining in-vehicle time in either the cross-sectional or longitudinal samples. Given these findings, we recommend that exposure modelers subdivide their population activity data into at least season/temperature, precipitation, and day-type "cohorts" as these factors are important discriminating variables affecting where people spend their time.

AN - 73534802; 12908862 AB - A prior case-control study found a positive, monotonic exposure-response relationship between exposure to diesel exhaust and lung cancer among decedents of the Central States Conference of the International Brotherhood of Teamsters. In response to critiques of the Teamsters' exposure estimates by the Health Effects Institute's Diesel Epidemiology Panel, historical exposures and associated uncertainties are investigated here. Historic diesel exhaust exposures are predicted as a function of heavy-duty diesel truck emissions, increasing use of diesel engines, and occupational elemental carbon (EC) measurements taken during the late 1980s and early 1990s. EC from diesel and nondiesel sources is distinguished in light of recent studies indicating a substantial contribution of gasoline vehicles to ambient EC. Monte Carlo sampling is used to characterize exposure distributions. The methodology used in this article-a probabilistic model for historical exposure assessment-is novel.

AN - 73501248; 12873012 AB - Geochemical and microbiological factors that control long-term performance of subsurface permeable reactive barriers were evaluated at the Elizabeth City, North Carolina, and the Denver Federal Center, Colorado, sites. These ground water treatment systems use zero-valent iron filings (Peerless Metal Powders Inc.) to intercept and remediate chlorinated hydrocarbon compounds at the Denver Federal Center (funnel-and-gate system) and overlapping plumes of hexavalent chromium and chlorinated hydrocarbons at Elizabeth City (continuous wall system). Zero-valent iron at both sites is a long-term sink for carbon, sulfur, calcium, silicon, nitrogen, and magnesium. After about four years of operation, the average rates of inorganic carbon (IC) and sulfur (S) accumulation are 0.09 and 0.02 kg/m2/year, respectively, at Elizabeth City where upgradient waters contain <400 mg/L of total dissolved solids (TDS). At the Denver Federal Center site, upgradient ground water contains 1000 to 1200 mg/L TDS and rates of IC and S accumulation are as high as 2.16 and 0.80 kg/m2/year, respectively. At both sites, consistent patterns of spatially variable mineral precipitation and microbial activity are observed. Mineral precipitates and microbial biomass accumulate the fastest near the upgradient aquifer-Fe0 interface. Maximum net reductions in porosity due to the accumulation of sulfur and inorganic carbon precipitates range from 0.032 at Elizabeth City to 0.062 at the Denver Federal Center (gate 2) after about four years. Although pore space has been lost due the accumulation of authigenic components, neither site shows evidence of pervasive pore clogging after four years of operation.

AN - 73495683; 12874868 AB - Measurements for determining of the path of groundwater migration remain an important tool in the overall assessment of environmental processes and transport of pollutants. This paper examines a multiwavelength laser for the determination of eosin, a groundwater tracer, using capillary electrophoresis/laser-induced fluorescence (CE-LIF) at excitation wavelength 514.5 nm. Eosin was one of four dyes used in a study of adjacent resource conservation and recovery act (RCRA) and Superfund sites (created by the comprehensive environmental response, compensation, and liability act) that routinely relied on spectrofluorimetry for determination as we have previously reported. However, the improved specificity of CE-LIF is further illustrated in this work applied to the analysis of adsorbent pads placed in monitoring wells after dye injection and flushing from injection wells. The multiwavelength laser provided the capability to analyze for several dyes with one laser. The advantages/disadvantages of CE-LIF versus spectrofluorimetry are discussed. Spectrofluorimetry is fast and sensitive and will likely continue to be the primary workhorse technique. CE-LIF could provide confirmation when greater specificity is needed in a regulatory context.

AN - 73461025; 12842770 AB - Following our first report on elevated polybrominated diphenyl ether (PBDE) concentrations in California women, we expanded our investigation to include diverse groups of local women. We analyzed additional adipose and serum samples collected in the late 1990s from San Francisco Bay Area women participating in a breast cancer study and in a reproductive study, respectively. Adipose samples (n = 32) were analyzed by low-resolution mass spectrometry in negative-ion chemical ionization mode, whereas serum samples (n = 50) were analyzed by dual-column gas chromatography with electron capture detection. The results confirmed our earlier findings. Concentrations of 2,2,4,4 -tetrabromodiphenyl ether (BDE-47) in contemporary California women ranged between 5 and 510 ng/g lipid, with a median (16.5 ng/g lipid) 3-10 times higher than those reported from Europe. In contrast, PBDEs were not measurable in any of 420 archived serum samples collected in the 1960s from San Francisco Bay Area women participating in a study of child development. BDE-47 concentrations did not increase with age or with concentrations of a polychlorinated biphenyl (PCB-153), suggesting other routes of exposure in addition to diet. Rising body burdens of endocrine-disrupting chemicals such as PBDEs may pose a potential public health threat.

AN - 73453413; 12759813 AB - Stable isotopes are increasingly being used as tracers in environmental studies. One application is to use isotopic ratios to quantitatively determine the proportional contribution of several sources to a mixture, such as the proportion of various pollution sources in a waste stream. In general, the proportional contributions of n+1 different sources can be uniquely determined by the use of n different isotope system tracers (e.g., delta13C, delta15N, delta18O) with linear mixing models based on mass balance equations. Often, however, the number of potential sources exceeds n+1, which prevents finding a unique solution of source proportions. What can be done in these situations? While no definitive solution exists, we propose a method that is informative in determining bounds for the contributions of each source. In this method, all possible combinations of each source contribution (0-100%) are examined in small increments (e.g., 1%). Combinations that sum to the observed mixture isotopic signatures within a small tolerance (e.g., +/-0.1 per thousand ) are considered to be feasible solutions, from which the frequency and range of potential source contributions can be determined. To avoid misrepresenting the results, users of this procedure should report the distribution of feasible solutions rather than focusing on a single value such as the mean. We applied this method to a variety of environmental studies in which stable isotope tracers were used to quantify the relative magnitude of multiple sources, including (1) plant water use, (2) geochemistry, (3) air pollution, and (4) dietary analysis. This method gives the range of isotopically determined source contributions; additional non-isotopic constraints specific to each study may be used to further restrict this range. The breadth of the isotopically determined ranges depends on the geometry of the mixing space and the similarity of source and mixture isotopic signatures. A sensitivity analysis indicated that the estimated ranges vary only modestly with different choices of source increment and mass balance tolerance parameter values. A computer program (IsoSource) to perform these calculations for user-specified data is available at http://www.epa.gov/wed/pages/models.htm.
