  12. EPA, OSHA DOT view hazards differently: Part 2 -- Reactivity and toxicity

    SciTech Connect

    Wray, T.K.

    1993-05-01

    DOT, EPA and OSHA definitions of reactivity and toxicity are similar in some cases, and seem to be contradictory in others. For example, the agencies' definitions of reactivity are comparable in most cases, but they are not always obvious. The toxicity definitions clearly delineate the responsible authority. OSHA's definitions are based on health hazards, EPA's on damage to health or the environment, and DOT's on causing a health hazard during transportation. There is considerable disagreement among environmental, health and safety professionals about which LD[sub 50] or LC[sub 50] levels indicate a true toxic response. Industrial hygienists and toxicologists know the answer does not exist. Individual tolerance, lifestyle, synergistic effects and inadequate data disallow calculation of definitive toxicity values. Exposure values are designed specifically to establish an acceptable safe level below which the average person can be exposed repeatedly with no deleterious effect. The no-threshold tenet held by EPA regarding carcinogens emphasizes the dearth of good toxicological knowledge. OSHA and its research arm, the National Institute for Occupational Safety and Health, stipulate that exposure to carcinogens be reduced to the lowest possible level.

  19. Improving the U.S. EPA Toxic Release Inventory database for environmental health research.

    PubMed

    Neumann, C M

    1998-01-01

    In 1986, Congress passed the Emergency Planning and Community Right-to-Know Act (EPCRA) in response to the tragic death of thousands of people in Bhopal, India, following the accidental release of the toxic gas methyl isocyanate (MIC) from a Union Carbide facility. As a component of EPCRA, certain manufacturers are required to report annually the total mass (pounds per year, lb/yr) of toxic chemicals released into the environment (air, water, land, or underground injection), treated on-site, or shipped off-site for further waste treatment. This information is compiled by the U.S. Environmental Protection Agency (EPA) into a publicly accessible database known as the Toxic Release Inventory (TRI). The TRI database is designed to encourage pollution prevention and waste reduction by increasing public access to and knowledge of environmental chemical releases. EPCRA has been generally considered by industry, government, and community representatives as one of the most successful environmental laws in U.S. history. Over the past few years, EPA has initiated a three-phased expansion to EPCRA reporting requirements that will enhance the overall usefulness of the TRI database. The focus of this article is to discuss these changes and highlight several current uses of the TRI database in environmental health research. PMID:9644330

  15. The U.S. EPA Geographic Information System for mapping environmental releases of Toxic Chemical Release Inventory (TRI) chemicals.

    PubMed

    Stockwell, J R; Sorensen, J W; Eckert, J W; Carreras, E M

    1993-04-01

    This study characterizes the environmental releases of toxic chemicals of the Toxic Chemical Release Inventory (TRI) in the southeastern United States by using the U.S. Environmental Protection Agency (EPA) Geographic Information System (GIS) to map them. These maps show that the largest quantities of TRI releases in the Southeast are usually near densely populated areas. This GIS mapping approach takes the first steps in defining those areas in the region which may be potential exposure zones and which could be strategic targets for future risk screening efforts in this geographic area.

  11. Statutory complexity disguises agency capture in Citizens Coal Council v. EPA

    SciTech Connect

    Mullen, R.

    2007-07-01

    In Citizens Coal Council v. EPA, an en banc panel for the Sixth Circuit Court of Appeals considered a challenge to EPA regulations promulgated pursuant to the Clean Water Act (CWA). The EPA promulgated the regulations in an attempt to incentivize coal companies to remine once abandoned mine sites. Petitioners, two nonprofit environmental organizations, claimed that the regulations violated the Clean Water Act and Administrative Procedure Act by allowing coal companies to remine without adhering to any enforceable pollution limitations. The EPA countered that more remining would improve water quality at abandoned sites. The Sixth Circuit rejected Petitioners' claims, finding that the EPA's regulations were reasonably consistent with the CWA's goal of restoring the integrity of the nation's waters. In so holding, the court struggled to understand the meaning of the CWA's complex procedural and technical language, and allowed the EPA to justify the rule based on the CWA's broad statement of purpose. Such superficial judicial review sets a dangerous precedent in environmental law, because it exacerbates the risk of agency capture. A captured agency promulgates regulations that benefit-industry, not the environment. Without the judiciary acting as a meaningful check against agency capture, the public loses a valuable tool in the fight against major-industrial polluters like the domestic coal industry. Citizens Coal Council therefore stands as a cautionary tale, a warning sign that the judiciary may be unable to identify agency capture where the regulations at issue are promulgated pursuant to a complex statute like the Clean Water Act.

  14. Developments in EPA`s air dispersion modeling for hazardous/toxic releases

    SciTech Connect

    Touma, J.S.

    1995-12-31

    Title 3 of the 1990 Clean Air Act Amendments (CAAA) lists many chemicals as hazardous air pollutants and requires establishing regulations to prevent their accidental release, and to minimize the consequence, if any such releases occur. With the large number of potential release scenarios that are associated with these chemicals, there is a need for a systematic approach for applying air dispersion models to estimate impact. Because some chemicals may form dense gas clouds upon release, and dispersion models that can simulate these releases are complex, EPA has paid attention to the development of modeling tools and guidance on the use of models that can address these types of releases.

    1990-10-01

    The U.S. Environmental Protection Agency (U.S. EPA) has advocated the establishment of general and scientific guidelines for the evaluation of toxicological data and their use in deriving benchmark values to protect exposed populations from adverse health effects. The Agency's reference dose (RfD) methodology for deriving benchmark values for noncancer toxicity originally addressed risk assessment of oral exposures. This paper presents a brief background on the development of the inhalation reference dose (RfDi) methodology, including concepts and issues related to addressing the dynamics of the respiratory system as the portal of entry. Different dosimetric adjustments are described that were incorporated into the methodology to account for the nature of the inhaled agent (particle or gas) and the site of the observed toxic effects (respiratory or extra-respiratory). Impacts of these adjustments on the extrapolation of toxicity data of inhaled agents for human health risk assessment and future research directions are also discussed.

    1987-01-01

    In January 1986 the U.S. Environmental Protection Agency (EPA) adopted a Wetlands Research Plan (Zedler and Kentula 1986). The plan describes the research necessary to assist the Agency in implementing its responsibilities for protecting wetlands, including Section 404 of the Clean Water Act. Three research needs were identified and an emphasis on freshwater systems was recommended. Research will be implemented to: (1) assess the water quality functions of wetlands; (2) develop methods to predict the cumulative impact(s) associated with wetland loss; and (3) improve the formulation and evaluation of wetland creation/ restoration projects required as mitigation for unavoidable impacts.

    Computational toxicology combines data from high-throughput test methods, chemical structure analyses and other biological domains (e.g., genes, proteins, cells, tissues) with the goals of predicting and understanding the underlying mechanistic causes of chemical toxicity and for predicting toxicity of new chemicals and products. A key feature of such approaches is their reliance on knowledge extracted from large collections of data and data sets in computable formats. The U.S. Environmental Protection Agency (EPA) has developed a large data resource called ACToR (Aggregated Computational Toxicology Resource) to support these data-intensive efforts. ACToR comprises four main repositories: core ACToR (chemical identifiers and structures, and summary data on hazard, exposure, use, and other domains), ToxRefDB (Toxicity Reference Database, a compilation of detailed in vivo toxicity data from guideline studies), ExpoCastDB (detailed human exposure data from observational studies of selected chemicals), and ToxCastDB (data from high-throughput screening programs, including links to underlying biological information related to genes and pathways). The EPA DSSTox (Distributed Structure-Searchable Toxicity) program provides expert-reviewed chemical structures and associated information for these and other high-interest public inventories. Overall, the ACToR system contains information on about 400,000 chemicals from 1100 different sources. The entire system is built using open source tools and is freely available to download. This review describes the organization of the data repository and provides selected examples of use cases. PMID:22408426

    This report describes a potential regulatory approach that the U.S. EPA could use for controlling sewage-sludge incinerators. The approach utilizes a most-exposed individual risk assessment to ensure that sludge-incineration air emissions will not cause an unacceptable health risk. An incinerator facility can demonstrate compliance using a three-tiered system which proceeds from a simple worst case calculation to a more resource intensive site-specific demonstration. A key part of the tiering system is development of an accurate and reliable emissions data base for U.S. sludge incinerators that can be used to develop reasonable worst case emission-control factors. The results of testing to date are discussed in the paper.

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

    2010-02-01

    In the 2007 report Toxicity Testing in the 21st Century: A Vision and a Strategy, the U.S. National Academy of Sciences envisioned a major transition in toxicity testing from cumbersome, expensive, and lengthy in vivo testing with qualitative endpoints, to in vitro robotic high-throughput screening with mechanistic quantitative parameters. Recognizing the need for agencies to partner and collaborate to ensure global harmonization, standardization, quality control and information sharing, the U.S. Environmental Protection Agency is leading by example and has established an intra-agency Future of Toxicity Testing Workgroup (FTTW). This workgroup has produced an ambitious blueprint for incorporating this new scientific paradigm to change the way chemicals are screened and evaluated for toxicity. Four main components of this strategy are discussed, as follows: (1) the impact and benefits of various types of regulatory activities, (2) chemical screening and prioritization, (3) toxicity pathway-based risk assessment, and (4) institutional transition. The new paradigm is predicated on the discovery of molecular perturbation pathways at the in vitro level that predict adverse health effects from xenobiotics exposure, and then extrapolating those events to the tissue, organ, or whole organisms by computational models. Research on these pathways will be integrated and compiled using the latest technology with the cooperation of global agencies, industry, and other stakeholders. The net result will be that chemical toxicity screening will become more efficient and cost-effective, include real-world exposure assessments, and eliminate currently used uncertainty factors.

    2006-01-01

    The US Environmental Protection Agency (EPA) recently issued a Staff Paper that articulates current risk assessment practices. In section 4.1.3, EPA states, "... effects that appear to be adaptive, non-adverse, or beneficial may not be mentioned." This statement may be perceived as precluding risk assessments based on non-default risk models, including the hormetic--or biphasic--dose-response model. This commentary examines several potential interpretations of this statement and the anticipated impact of ignoring hormesis, if present, in light of necessary conservatism for protecting human and environmental health, and the potential for employing alternative risk assessment approaches.

    The U.S. Environmental Protection Agency (EPA) Endocrine Disruptor Screening Program (EDSP) currently relies on an initial screening battery (Tier 1) consisting of five in vitro and six in vivo assays to evaluate a chemical's potential to interact with the endocrine system. Chemical companies may request test waivers based on Other Scientifically Relevant Information (OSRI) that is functionally equivalent to data gathered in the screening battery or that provides information on a potential endocrine effect. Respondents for 47 of the first 67 chemicals evaluated in the EDSP submitted OSRI in lieu of some or all Tier 1 tests, seeking 412 waivers, of which EPA granted only 93. For 20 of the 47 chemicals, EPA denied all OSRI and required the entire Tier 1 battery. Often, the OSRI accepted was either identical to data generated by the Tier 1 assay or indicated a positive result. Although identified as potential sources of OSRI in EPA guidance, Part 158 guideline studies for pesticide registration were seldom accepted by EPA. The 93 waivers reduced animal use by at least 3325 animals. We estimate 27,731 animals were used in the actual Tier 1 tests, with additional animals being used in preparation for testing. Even with EPA's shift toward applying 21st-century toxicology tools to screening of endocrine disruptors in the future, acceptance of OSRI will remain a primary means for avoiding duplicative testing and reducing use of animals in the EDSP. Therefore, it is essential that EPA develop a consistent and transparent basis for accepting OSRI. PMID:24151143

    Single point estimates of human health hazard/toxicity values such as a reference dose (RfD) are generally used in chemical hazard and risk assessment programs for assessing potential risks associated with site- or use-specific exposures. The resulting point estimates are often used by risk managers for regulatory decision-making, including standard setting, determination of emission controls, and mitigation of exposures to chemical substances. Risk managers, as well as stakeholders (interested and affected parties), often have limited information regarding assumptions and uncertainty factors in numerical estimates of both hazards and risks. Further, the use of different approaches for addressing uncertainty, which vary in transparency, can lead to a lack of confidence in the scientific underpinning of regulatory decision-making. The overarching goal of this paper, which was developed from an invited participant workshop, is to offer five approaches for presenting toxicity values in a transparent manner in order to improve the understanding, consideration, and informed use of uncertainty by risk assessors, risk managers, and stakeholders. The five approaches for improving the presentation and communication of uncertainty are described using U.S. Environmental Protection Agency's (EPA's) Integrated Risk Information System (IRIS) as a case study. These approaches will ensure transparency in the documentation, development, and use of toxicity values at EPA, the Agency for Toxic Substances and Disease Registry (ATSDR), and other similar assessment programs in the public and private sector. Further empirical testing will help to inform the approaches that will work best for specific audiences and situations. PMID:26827183

    During the past 3 years, EPA's ECAO/Cincinnati has developed a method to rank chemicals based on chronic toxicity data. This ranking system reflects two primary attributes of every chemical: the minimum effective dose and the type of effect elicited at that dose. The purpose for developing this chronic toxicity ranking system was to provide the EPA with the technical background required to adjust the RQs of hazardous substances designated in Section 101(14) of CERCLA or "Superfund." This approach may have applications to other areas of interest to the EPA and other regulatory agencies where ranking of chemicals based on chronic toxicity is desired. PMID:3843499

  17. After two decades, EPA`s hazardous waste regulations still rule

    SciTech Connect

    Wray, T.K.

    1996-11-01

    The Environmental Protection Agency (EPA) promulgated the first hazardous waste management regulations nearly 20 years ago under the Resource Conservation and Recovery Act. The rules were designed to ensure that hazardous wastes would be managed in an environmentally safe manner from cradle to grave--from the point of generation to final disposal. The regulations have undergone several revisions but still consist of four basic parts--waste identification, generator rules, transporter rules, and treatment, storage and disposal rules. This article focuses on rules for generators. EPA regulations define three classes of generators, based on waste volume and toxicity. All generators must obtain an EPA identification number, which requires completion and filing of form 8700-12 ``Notification of Hazardous Waste Activity.`` The alphanumeric identification numbers typically are issued by state environmental regulatory agencies.

    Henriques, W.D.; Dixon, K.R.

    1994-12-31

    Using data from the Environmental Protection Agency`s Toxic Release Inventory 1988 (EPA TRI88), pollutant concentration estimates were modeled for a point source air release of 1,1,1-trichloroethane at the Savannah River Plant located in Aiken, South Carolina. Estimates were calculating using the EPA`s SCREEN model utilizing typical meteorological conditions to determine maximum impact of the plume under different mixing conditions for locations within 100 meters of the stack. Input data for the SCREEN model were then manipulated to simulate the impact of the release under urban conditions (for the purpose of assessing future landuse considerations) and under flare release options to determine if these parameters lessen or increase the probability of human or wildlife exposure to significant concentrations. The results were then compared to EPA reference concentrations (RfC) in order to assess the size of the buffer around the stack which may potentially have levels that exceed this level of safety.

    1990-12-01

    The Agency for Toxic Substances and Disease Registry is required to conduct a health assessment of any site that is listed on or proposed for the US Environmental Protection Agency's National Priorities List. Sixteen US Department of Energy (DOE) sites currently fall into this category. Health assessments contain a qualitative description of impacts to public health and the environment from hazardous waste sites, as well as recommendations for actions to mitigate or eliminate risk. Because these recommendations may have major impacts on compliance activities at DOE facilities, the health assessments are an important source of information for the monitoring activities of DOE's Office of Environmental Compliance (OEC). This report provides an overview of the activities involved in preparing the health assessment, its role in environmental management, and its key elements.

    An easy-to-use indoor-air-quality (IAQ) model is described. It is multi-compartmented and based on a well-mixed mixing model. Sources and sinks are allowed in each compartment. A menu-driven fill-in-the-form user interface controls program flow and is used to obtain data from the user. On-screen graphical output is provided. The model estimates the effects of heating, ventilation, and air conditioning (HVAC), air cleaning, room-to-room air movement, and natural ventilation on pollutant concentrations. Experiments conducted in the EPA test house using moth crystal cakes for model verification are described. The agreement between small chamber emission factors, model predictions, and test house data is very good. Predicted weight loss of the moth crystal cakes was within 5% of the measured weight loss. Predicted room concentrations of p-dichlorobenzene are within 20% of the measured values. Future directions for model development and experimental studies are discussed.

    An interlaboratory study in which 20 laboratories participated was conducted to provide precision and accuracy statements for the proposed EPA Method 604-Phenols for measuring concentrations of the Category 8 chemicals phenol, 2,4-dimethylphenol, 2-chlorophenol, 4-chloro-3-methylphenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, pentachlorophenol, 2-nitrophenol, 4-nitrophenol, 4,6-dinitro-2-methylphenol, and 2,4-dinitrophenol in municipal and industrial aqueous discharges. The method provides for the determination of the phenols by gas chromatography (GC) with flame ionization detection (FID) or derivatization and detection by electron capture (EC). The study design was based on Youden's plan for collaborative tests of analytical methods. Three Youden pair samples of the test compounds were spiked into six types of test waters and then analyzed.

    This document announces the conclusions of the EPA evaluation of the POLARION-X device under the provisions of Section 511 of the Motor Vehicle Information and Cost Savings Act. The evaluation of the POLARION-X device was conducted upon receiving an application from the marketer of the device. The POLARION-X is installed in the fuel line between the pump and the carburetor. It incorporates two permanent magnets which subject the fuel to a magnetic field. This device is claimed to reduce emissions, to improve fuel economy and performance, to provide more complete combustion, to eliminate engine carbon buildup and dieseling, and to reduce the octane requirements of the engine. The Environmental Protection Agency (EPA) fully considered all of the information submitted by the applicant. The overall conclusion was that for the POLARION-X there is no reason to expect that the device will improve either the emissions or fuel economy of a typical motor vehicle in proper operating conditions.

    The Cold Weather Plume Study (CWPS) was a field measurement program carried out in February 1981 under the joint sponsorship of the U.S. Environmental Protection Agency and the Electric Power Research Institute. Its objective was to generate a data base suitable for quantitative analysis of the mesoscale physical dynamics and SOx, NOx chemistry of the plume of the 1320-MW coal-fired Kincaid power plant near Springfield, Illinois. The data base was intended to complement similar measurements made by other EPA and EPRI studies in the same region during other seasons. Measurements included in-situ chemical measurements from two instrumented aircraft, remote-sensing lidar measurements and meteorological measurements from a surface station, two towers, and from vertical soundings. The report provides a brief overview of the measurement platforms, the measured parameters, and the daily experiments, and describes and documents the data base available on magnetic tapes and in hard copy form.

    The biological stability of treated drinking water has become a major concern for water utilities. The U.S. E.P.A. is concerned from the perspective of coliform MCL compliance and remediation of coliform biofilm problems. The levels of readily assimilable nutrients present in treated water are affected by water treatment processes, but of greatest concern are those processes, such as ozonation, that cause increases in the levels of assimilable organic carbon (AOC) and therefore contribute to biological instability of the water. Thus, the combined use of ozonation (pre-oxidant) and a lower disinfectant residual as an approach to reducing disinfectant byproducts may result in increased bacterial growth, including coliforms, in the distribution system. Information is needed on: the AOC flux level that stimulate coliform growth in biofilm: the specific nutrients and concentrations that can stimulate growth of both coliforms and HPC; treatment strategies to reduce AOC levels and strategies to effectively control biofilm formation where AOC levels cannot be reduced.

    1992-01-01

    The Agency for Toxic Substances and Disease Registry (ATSDR) report "The Public Health Implications of Medical Waste: A Report to Congress" has been finalized and submitted to Congress. The report is a comprehensive review of all available data and information on the subject. Based on the data developed in the report, ATSDR concludes that the general public is not likely to be adversely affected by medical waste generated in the traditional health setting. However, the increase of in-home health care and other sources of nonregulated medical waste (e.g., intravenous drug users) provides opportunities for the general public to contact medical waste. In addition, ATSDR concludes that public health concerns exist for selected occupations involved with medical waste. These populations include janitorial and laundry workers, nurses, emergency medical personnel, and refuse workers. The ATSDR report also defines what material should be managed as medical waste and identifies research needs related to medical waste. PMID:1486856

    1987-04-29

    Traditionally, the oral route has been the most common route of administration in bioassays which tested the potential carcinogenicity of chemicals. Regulatory agencies, however, prefer to have test chemicals applied by the same route as expected human exposure, whenever possible. Since human exposure to industrial chemicals is frequently via the dermal route, this has become a route of choice for animal testing of certain chemicals. However, protocol design for dermal bioassays presents many unique problems which must be addressed before guidelines for bioassays by the dermal route can be formulated. Furthermore, it may be feasible to develop a limited dermal protocol to screen certain classes of chemicals such as acrylates/methacrylates. Recognizing the need for this workshop, it was designed in two distinct parts; to address the problems inherent in the development of a generic protocol for dermal bioassays and, a specific limited dermal bioassay protocol for acrylates/methacrylates.

    The U.S. Environmental Protection Agency (EPA) is not investing enough money in the science needed for the agency to make sound environmental policy decisions, according to several witnesses who testified before a U.S. House of Representatives subcommittee on 16 March. The House Science Subcommittee on Environment, Technology, and Standards brought together George Gray, EPA associate administrator for research and development, and three other witnesses to discuss the proposed cuts to EPA's Office of Research and Development (ORD), the agency's primary research arm. The Bush Administration has proposed cutting the ORD budget by six percent in Fiscal Year 2007, to $557 million. This would continue a trend of decreases for ORD, whose budget would decline by 14 percent from FY2004 to FY2007 if the cuts are approved by the U.S. Congress.

    Under a consent agreement among the Environmental Protection Agency (EPA) and proponents both for and against stricter regulation, EPA is to issue a new coal ash disposal rule by the end of 2014. Laboratory toxicity investigations often yield conservative estimates of toxicity because many standard test species are more sensitive than resident species, thus could provide information useful to the rule-making. However, few laboratory studies of coal ash toxicity are available; most studies reported in the literature are based solely on field investigations. This brief communication describes a broad range of toxicity studies conducted for the Tennessee Valley Authority (TVA) Kingston ash spill, results of which help provide additional perspective on the toxicity of coal ash.

    Life Cycle Impact Assessment (LCIA) and Risk Assessment (RA) employ different approaches to evaluate toxic impact potential for their own general applications. LCIA is often used to evaluate toxicity potentials for corporate environmental management and RA is often used to evaluate a risk score for environmental policy in government. This study evaluates the cancer, non-cancer, and ecotoxicity potentials and risk scores of chemicals and industry sectors in the United States on the basis of the LCIA- and RA-based tools developed by U.S. EPA, and compares the priority screening of toxic chemicals and industry sectors identified with each method to examine whether the LCIA- and RA-based results lead to the same prioritization schemes. The Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) is applied as an LCIA-based screening approach with a focus on air and water emissions, and the Risk-Screening Environmental Indicator (RSEI) is applied in equivalent fashion as an RA-based screening approach. The U.S. Toxic Release Inventory is used as the dataset for this analysis, because of its general applicability to a comprehensive list of chemical substances and industry sectors. Overall, the TRACI and RSEI results do not agree with each other in part due to the unavailability of characterization factors and toxic scores for select substances, but primarily because of their different evaluation approaches. Therefore, TRACI and RSEI should be used together both to support a more comprehensive and robust approach to screening of chemicals for environmental management and policy and to highlight substances that are found to be of concern from both perspectives.

    Bleiler, J.A.

    1996-09-01

    A recent Environmental Protection Agency initiative may enable contaminated-site owners and other responsible parties to negotiate more realistic sediment cleanup actions with state and federal agencies. EPA in December 1994 issued Equilibrium Partitioning Approach to Predicting Metal Bioavailability in Sediments and the Derivation of Sediment Quality Criteria (SQC) for Metals, a report on metals contamination in sediments. This document marks the agency`s first national initiative to develop SQC for metals. Because it could reduce site remediation costs substantially, the new approach may be good news for industry. The initiative`s goal is to protect sediment-dwelling organisms from toxic levels of such metals as cadmium, lead, zinc, nickel and copper.

    Biodiesel use as a fuel is increasing globally as an alternate to petroleum sources. To comprehensively assess the effects of the use of biodiesel as an energy source, end stage uses of biodiesel such as the effects of inhalation of combusted products on human health must be incorporated. To date, few reports concerning the toxicological effects of the emissions of combusted biodiesel or blends of biodiesel on surrogates of health effects have been published. The relative toxicity of the combusted biodiesel emissions compared to petroleum diesel emissions with short term exposures is also not well known. To address the paucity of findings on the toxicity of combusted biodiesel emissions, studies were undertaken at the U.S. Environmental Protection Agency laboratories in Research Triangle Park, North Carolina. The studies used a variety of approaches with nonhuman animal models to examine biological responses of the lung and cardiovascular systems induced by acute and repeated exposures to pure biodiesel and biodiesel blended with petroleum diesel. Effects of the emissions on induction of mutations in bacterial test strains and mammalian DNA adducts were also characterized and normalized to engine work load. The emissions were characterized as to the physicochemical composition in order to determine the magnitude of the differences among the emissions utilized in the studies. This article summarizes the major finding of these studies which are contained within this special issue of Inhalation Toxicology. The findings provided in these articles provide information about the toxicity of biodiesel emissions relative to petroleum diesel emissions and which can be utilized in a life cycle analyses of the effects of increased biodiesel usage.

    Attractive toxic sugar bait (ATSB) is a highly effective method which targets mosquitoes based on their sugar foraging behavior, by presenting baits of attractive compounds in combination with sugar and oral toxin to local mosquito populations. Environmental concerns and insecticide selection-pressure have prompted investigations of novel, ecologically-harmless substances which can be used as insecticides. This study examined the efficacy of microencapsulated garlic-oil as the oral toxin component of ATSB for controlling Anopheles sergentii populations inhabiting desert-surrounded wetlands in Israel. ATSB solution containing 0.4% encapsulated garlic oil was applied to local vegetation around a streamlet located in the lower Jordan Valley. To determine the propensity of bait ingestion, and assess the potential ecological impact of the method, mosquito and non-target specimens were collected and tested for the presence of natural plant- or attractive sugar bait (ASB)-derived sugars. Over the experimental period, biting-pressure values in the ATSB treatment site decreased by 97.5%, while at the control site, treated with non-toxic ASB, no significant changes were observed. Approximately 70% of the mosquitoes collected before both treatments, as well as those captured following the application of ASB at the control site, were found to have ingested sugar prior to capture. Non-target insects were minimally affected by the treatment when ATSB was applied to foliage of non-flowering plants. Of the non-Diptera species, only 0.7% of the sampled non-target insects were found to have ingested ASB-solution which was applied to green vegetation, compared with 8.5% which have foraged on ASB-derived sugars applied to flowering plants. Conversely, a high proportion of the non-target species belonging to the order Diptera, especially non-biting midges, were found to have ingested foliage-applied ASB, with more than 36% of the specimens collected determined to have foraged on bait

  19. Toxic releases from power plants

    SciTech Connect

    Rubin, E.S.

    1999-09-15

    Beginning in 1998, electric power plants burning coal or oil must estimate and report their annual releases of toxic chemicals listed in the Toxics Release Inventory (TRI) published by the US Environmental Protection Agency (EPA). This paper identifies the toxic chemicals of greatest significance for the electric utility sector and develops quantitative estimates of the toxic releases reportable to the TRI for a representative coal-fired power plant. Key factors affecting the magnitude and types of toxic releases for individual power plants also are discussed. A national projection suggests that the magnitude of electric utility industry releases will surpass those of the manufacturing industries which current report to the TRI. Risk communication activities at the community level will be essential to interpret and provide context for the new TRI results.

    1983-05-01

    This report announces the conclusions of the EPA evaluation of the Optimizer device under the provisions of section 511 of the Motor Vehicle Information and Cost Savings Act. The evaluation of the Optimizer was conducted upon the application of the manufacturer. The basic device is a combustion catalyst consisting of an electric fuel heater containing a bed of platinum deposited on an inert substrate. The remainder of the system includes a heater relay, a condenser to cool the fuel to operating temperature, and the associated plumbing. According to the applicant, the device introduces a very small amount of platinum into the fuel. This enhances the combustion process and allows ignition timing to be advanced. The device, coupled with the ignition timing adjustments, is claimed to improve fuel economy, increase performance, and reduce engine maintenance while keeping emissions low. EPA fully considered all of the information submitted by the applicant. The evaluation of the Optimizer device was based on that information and EPA's engineering judgement. The overall conclusion is that, for most vehicles, the device and the prescribed ignition timing adjustments of the engine will cause a small improvement in fuel economy and a large increase in NOx (oxides of nitrogen) emissions.

    1982-02-25

    On May 19, 1980, EPA promulgated regulations applicable to owners and operators of hazardous waste treatment, storage, and disposal facilities which prohibited the landfill disposal of most containerized liquid waste or waste containing free liquid on and after November 19, 1981. Further on June 29, 1981, EPA amended its hazardous waste management regulations so as to extend the compliance date of the restriction on the landfill disposal of containerized liquid ignitable wastes to coincide with the compliance data of the general restriction on landfill disposal of liquids. The Agency is today extending the compliance date on both these requirements until May 26, 1982, and, in a separate action, is proposing amendments to these restrictions. This extension of compliance dates is provided for the sole purpose of allowing time to complete the rulemaking action on today's proposed amendments. The Agency is also today exempting from the requirements of the hazardous waste management regulations, the acts of adding absorbent material to hazardous waste in containers and adding hazardous waste to absorbent material in a container, at the time waste is first placed in the container, in order to reduce the free liquids in a container.

    The US Environmental Protection Agency (EPA) announced its adjustments to the national air quality standards in late September after a mandatory five-year review process. The National Ambient Air Quality Standards (NAAQS) address fine and coarse particle pollution, also known as particulate matter (PM). The final action changes the 24-hour allowance for fine particulates, such as those emitted from coal-fired generation stacks, from 65 micrograms of particles per cubic meter of air to 35 {mu}g/m{sup 3}. EPA said this measure protects people from short-term exposure to fine particles. The annual standard will remain the same at 15 {mu}g/m{sup 3}. Carl Weilert of Burns and McDonnell gave some comments on implications of the standards in an interview with Power Engineering. 1 ref.

  12. EPA`s integrated nitrogen oxides strategy

    SciTech Connect

    Grano, D.H.

    1997-12-31

    Nitrogen oxides (NO{sub x}) are highly reactive and play a major role in the formation of various gases and particles in the atmosphere which lead to harmful effects on human health and welfare. This paper briefly describes the multiple impacts on human health and welfare that result from emissions of NO{sub x} and describes EPA`s strategy to integrate NO{sub x} reductions from various mobile and stationary sources in a balanced manner to achieve environmental benefits. Based on modeling information, it is clear that substantial reductions in NO{sub x} emissions over large geographic areas are needed if many densely populated areas of the nation are to attain the national ambient air quality standard for ozone. In addition to attainment of the health standard for ozone, the reduction of NO{sub x} emissions will also likely improve the nation`s environment by reducing adverse impacts of acid deposition, eutrophication of waterbodies, global warming, nitrogen dioxide, particulate matter, stratospheric ozone depletion, toxics, and visibility.

    The proposed Neurotoxicity Risk Assessment Guidelines (U.S. EPA, 1995c Fed. Reg. 60(192), 52032-52056) of the U.S. Environmental Protection Agency (EPA) were the subject of a workshop at the 1997 Meeting of the Society of Toxicology. The workshop considered the role of guidelines in the risk assessment process, the primary features, scientific basis, and implications of the guidelines for EPA program offices, as well as for industrial neurotoxicologists from the perspectives of both pesticides and toxic substances regulation. The U.S. National Academy of Sciences (NAS, 1983, Risk Assessment in the Federal Government: Managing the Process) established a framework for distinguishing risk management from risk assessment, the latter being the result of integrating hazard identification, hazard characterization, and exposure assessment data. The guidelines are intended to establish operating principles that will be used when examining data in a risk assessment context. The proposed neurotoxicity risk assessment guidelines provide a conceptual framework for deciding whether or not a chemically induced effect can be considered to be evidence of neurotoxicity. Topics in the proposed guidelines include structural and functional effects, dose-response and -duration considerations, and relationships between effects. Among the issues that must be considered are the multiplicity of chemical effects, the levels of biological organization in the nervous system, and the tests, measurements, and protocols used. Judgment of the adversity of an effect depends heavily on the amount and types of data available. The attribution of a chemically induced effect to an action on the nervous system depends on several factors such as the quality of the study, the nature of the outcome, dose-response and time-response relationships, and the possible involvement of nonneural factors. The guidelines will also serve as a reference for those conducting neurotoxicity testing, as well as establish a

  18. EPA in disarray: muzzling the watchdog

    SciTech Connect

    Goldberg, P.

    1981-12-01

    The average American's exposure to toxic industrial chemicals could double in the next 10 years as the chemical industry expands and chemicals continue to collect and concentrate in the environment because the administration plans to throw away needed environmental regulations along with the unneeded and ill-advised ones. The plan favors short-term economic gains for industry over long-term health and safety considerations. Budget cutbacks are eliminating funds for inspectors and increasing the risks of illegal dumping which accounts for an estimated 80% of chemical wastes. The author feels that Environmental Protection Agency (EPA) Director Ann Gorsuch, who brings no knowledge of chemistry or administration to the job, will halt funding for dump cleanups and delay the implementation of pollution regulations despite polls which show the public wants them to proceed.

    1989-01-01

    The emissions of a lean-burn natural-gas-fueled 3406 spark-ignited engine were determined on the EPA transient emission cycle for heavy-duty vehicle engines. The engine was rated at 350 hp at 1800 rpm. The engine was a minimally modified generator-set engine developed under the same GRI contract and was not optimized for truck applications or transient emissions. Transient emissions in g/hp-hr were 4.1 NOx, 9.2 total hydrocarbons, 0.84 non-methane hydrocarbons, 3.2 CO, 0.42 aldehydes, and 0.60 particulates. Steady-state emissions were also measured. The results indicate lean-burn spark-ignited engine technology is a promising approach to meeting 1994 EPA truck-engine-emission standards. NOx and CO standards can be readily met. Hydrocarbon emissions exceed the standard in the engine as presently configured but are believed to be controllable by improved air/fuel ratio control, combustion-system modification and/or an oxidation catalyst. The particulates were primarily from the lubricating oil and should be controllable with piston ring and valve-seal improvements and/or an oxidation catalyst.

    1985-04-01

    The document announces the conclusions of the EPA evaluation of the POLARION-X device under the provisions of Section 511 of the Motor Vehicle Information and Cost Savings Act. The second evaluation of the POLARION-X device was conducted upon receiving an application for evaluation from the marketer of the device. The device is a fuel magnet. It is claimed to reduce emissions, to improve fuel economy and performance, to provide more complete combustion, to eliminate engine carbon buildup and dieseling, and to reduce the octane requirements of the engine. EPA fully considered all of the previous correspondence and analyses that were incorporated in the prior evaluation. In addition, the intervening correspondence about the device and test fuel are also considered to apply to the application. The net result is that, except for the test data, the previous submission and the analyses of it are essentially unchanged. Based on engineering judgment and the results of test data, it is concluded that the POLARION-X device will not improve emissions or fuel economy.

    Di(2-ethylhexyl)phthalate (also known as DEHP, bis(2-ethylhexyl)phthalate, or BEHP; CAS Registry Number 117-81-7) is a widely-used plasticizer. It is found in numerous plastic articles, such as paints, inks, floor tiles, upholstery, shower curtains, footwear, plastic bags, food-packaging materials, toys, and medical tubing. Not surprisingly, DEHP appears at many waste sites. As part of its mandate, the Agency for Toxic Substances and Disease Registry (ATSDR) prepares toxicological profiles on hazardous chemicals that are of greatest public health concern at Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) National Priority List (NPL) sites. These profiles comprehensively summarize toxicological and environmental information. This article constitutes the release of the bulk of ATSDR's profile for DEHP (ATSDR, 1993) into the mainstream scientific literature. An extensive listing of human and animal health effects, organized by route, duration, and endpoint, is presented. Toxicological information on toxicokinetics, biomarkers, interactions, sensitive subpopulations, reducing toxicity after exposure, and relevance to public health is also included. Environmental information encompasses physical properties, production and use, environmental fate, levels seen in the environment, analytical methods, and a listing of regulations. ATSDR, at the behest of Congress and therefore the citizenry, prepares these profiles to inform the public about site contaminants. PMID:10786378

    A series of demonstration tests of the American Combustion, Inc., Thermal Destruction System was performed under the SITE program. This oxygen-enhanced combustion system was retrofit to the rotary-kiln incinerator at EPA's Combustion Research Facility. The system's performance was tested firing contaminated soil from the Stringfellow Superfund Site, both alone and mixed with a coal tar waste (KO87). Comparative performance with conventional incinerator operation was also tested. Compliance with the incinerator performance standards of 99.99% principal organic hazardous constituents (POHC) destruction and removal efficiency and particulate emissions of less than 180 mg/dscm at 7% O2 was measured for all tests. The Pyretron system was capable of in-compliance performance at double the mixed waste feedrate and at a 60% increase in batch waste charge mass than possible with conventional incineration. Scrubber blowdown and kiln ash contained no detectable levels of any of the POHCs chosen.

    1989-09-01

    The US Environmental Protection Agency (EPA) issued a final test rule (1985) for biphenyl on the authority of Section 4(a) of the Toxic Substances Control Act (TSCA). Contained within this rule was the requirement for generating chronic daphnid toxicity data for biphenyl. Biphenyl is used primarily to produce dye carriers, heat-transfer fluids and alkylated biphenyls. The acute toxicity of biphenyl to Daphnia magna has been reported. The 48-hr LC50 values were 4.7 and 2.1 mg/L, respectively. To date, the chronic toxicity of biphenyl to fish and aquatic invertebrates has not been investigated. The objective of this study was to determine the chronic toxicity of biphenyl to D. magna. The daphnid chronic toxicity test is designed to estimate the maximum acceptable toxicant concentration (MATC). The MATC is defined as the concentration falling between the highest concentration showing no effect and the next higher concentration showing a toxic effect when compared to the controls.

    PubMed Central

    Zelinkova, Zuzana; Wenzl, Thomas

    2015-01-01

    Occurrence and toxicity of polycyclic aromatic hydrocarbons (PAHs) have been extensively studied in countries all over the world. PAHs generally occur in complex mixtures which may consist of hundreds of compounds. The U.S. Environmental Protection Agency (EPA) proposed in the 1970 to monitor a set of 16 PAHs which are frequently found in environmental samples. This article reviews the suitability of the 16 EPA PAHs for the assessment of potential health threats to humans stemming from the exposure to PAHs by food ingestion. It presents details on analysis methods, the occurrence of PAHs in food, regulatory aspects, and related risk management approaches. In addition, consideration is given to newer evaluations of the toxicity of PAHs and the requirements for risk assessment and management stemming from them. PMID:26681897

  12. Understanding the EPA guidance on major source determinations for military installations

    SciTech Connect

    Ling, A.D.

    1997-12-31

    In August 1996, the Environmental Protection Agency (EPA) issued the first ever Clean Air Act (CAA) guidance directed specifically at military facilities. The Guidance, titled Major Source Determinations for Military Installations under the Air Toxics, New Source Review and Title V Operating Permit Programs of the Clean Air Act, was negotiated by an EPA/DoD workgroup that included field and headquarters EPA and DoD representatives, and was led by the Navy. This paper describes the development and contents of the guidance and the significant legal and policy issues raised. By statute and rule, all sources under common control on contiguous or adjacent property and belonging to the same two digit Standard Industrial Classification (SIC) Code must be aggregated when determining if the source is a major source. DoD requested that EPA develop the guidance because of a move by EPA to impose a fenceline-to-fenceline interpretation of what constitutes a major source for purposes of the three programs identified above. Such an interpretation could and did result in more stringent regulation of industrial sources on military installations than of similar industrial plants. The guidance establishes EPA`s allowable interpretation of two of the three key elements of the major source definition. First, the guidance specifies that common control occurs at the military service level; therefore, sources belonging to the Army, Navy, Marine Corps, Air Force, the National Guard or a Defense Agency that are located on the same installation could each be treated separately. Second, the guidance allows the military to assign SIC codes to functional industrial groupings in a manner similar to the private sector. Past practice grouped all national defense activities under the same SIC code.

    The proposed ERTS-DCS system is designed to allow EPA the capability to evaluate, through demonstrable hardware, the effectiveness of automated data collection techniques. The total effectiveness of any system is dependent upon many factors which include equipment cost, installation, maintainability, logistic support, growth potential, flexibility and failure rate. This can best be accomplished by installing the system at an operational environmental control agency (CAMP station) to insure that valid data is being obtained and processed. Consequently, it is imperative that the equipment interface must not compromise the validity of the sensor data nor should the experimental system effect the present operations of the CAMP station. Since both the system which is presently in use and the automatic system would be in operation in parallel, conformation and comparison are readily obtained.

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

    Over the next few months, the US Environmental Protection Agency (EPA) will be finalizing its proposal to revise the National Ambient Air Quality Standards (NAAQS) for fine and coarse particulate matter (PM). Since issuing the proposal in December 2005, the agency has sought comments from all interested parties, and will base its final decision on the record that was established through the comment period, which ended on April 17. In this issue articles present perspectives from some of the many non-EPA stakeholders who have played an important role in this review process. This article summarizes EPA's proposal, as well as the extensive process EPA goes through when setting air quality standards. 1 fig., 2 tabs.

    The bibliography contains citations concerning the Toxic Release Inventory (TRI) database issued by the Environmental Protection Agency (EPA). The TRI database was begun by EPA in response to Section 313 of the Emergency Planning and Community Right-to-Know Act of the Superfund Amendments and Reauthorization Act of 1986, which required EPA to establish an inventory by states of routine toxic chemical emissions from certain facilities. There are over 300 chemicals and categories on these lists. The reporting requirement applies to owners and operators of manufacturing facilities that employ 10 or more full-time employees and that manufacture, process, or otherwise use a tested toxic chemical in excess of specified threshold quantities. The data file is contained on diskettes in dBASE III format or LOTUS 1-2-3 format available from the National Technical Information Service (NTIS).

  15. Defining the scope of lender liability after Kelley v. EPA: Who will have safe harbor?

    SciTech Connect

    1995-08-01

    In 1980, Congress enacted CERCLA in order to clean up toxic waste sites and identify broad classes of people who would be financially responsible for the clean-up efforts. One of these broad classes of responsible parties includes owners or operators of hazardous waste sites. This category created enormous potential for liability risk for lenders who hold title to contaminated property as collateral. Congress created a {open_quotes}safe harbor{close_quotes} exemption from liability within the definition of owners and operators in order to protect lenders who held title merely as protection of a security interest. Conflicting interpretations have caused a great deal of confusion for lending institutions. In response to fears of unlimited liability expressed by lending institutions and in consideration of the federal government`s increasing role as a secured creditor, the Environmental Protection Agency (EPA) issued a regulation in 1992 that attempted to define clearly the scope of a lender`s liability under CERCLA. This rule provided the lending community with a precise standard by which to guide their actions in order to avoid incurring liability. In Kelley v. EPA, the EPA`s regulation that attempted to clarify issues of lender liability under CERCLA was struck down by the United States Court of Appeals for the D.C. Circuit. The court held that Congress had not granted the EPA authority to promulgate regulations that would define the scope of lender liability in private party litigation. It further determined that federal courts should evaluate claims in private cost recovery actions independent of the EPA`s {open_quotes}institutional view{close_quotes}. This note postulates that the Kelley decision to invalidate the rule once again exposes lenders to unlimited liability under CERCLA by leaving them to make decisions based on an ambiguous statutory provision that has been interpreted both broadly and narrowly in the past.

  19. Harmonization of standard toxicity test methods used in North America

    SciTech Connect

    Ingersoll, C.G.; Dwyer, F.J.; Ankley, G.T.

    1995-12-31

    Over the past two years, Environment Canada (EC) and the US Environmental Protection Agency (EPA) have developed standard methods for conducting toxicity and bioaccumulation tests with freshwater, estuarine, and marine sediments. Existing ASTM methods were used as a basis to harmonize these methods for conducting testing with either field-collected or laboratory-spiked sediments. For freshwater toxicity tests, methods are described by EC and EPA for the amphipod Hyalella azteca and the midges Chironomus tentans and C. riparius. Endpoints include 10- to 14-d survival of growth. Methods are also described by EPA for conducting 28-d bioaccumulation tests with the oligochaete Lumbriculus variegatus. For estuarine and marine toxicity tests, methods are described for several amphipods (i.e., Rhepoxynius abronius, Ampelisca abdita, Eohaustorius estuarius, Leptocheirus plumulosus). Endpoints include 10-d survival and reburial. EC is also developing methods for conducting toxicity tests with Atlantic, Pacific, and Arctic Canadian species of polychaetes. Methods are described by EPA for conducting 28-d bioaccumulation tests with a variety of mollusks (i.e., Macoma spp.) and polychaetes (i.e., Nereis spp.). Slight inconsistencies in methods between freshwater and estuarine/marine testing or between EC and EPA testing include: (1) static vs. flow-through conditions, (2) sieving of sediment, (3) types and quantity of food, (4) age of test organisms, or (4) duration of the test and required endpoints. Additional research is in progress to: (1) develop chronic toxicity tests with amphipods and midges measuring survival, growth, or reproduction, (2) develop whole-sediment toxicity identification evaluation (TIE) procedures, (3) refine sediment spiking procedures, and (4) field-validate laboratory tests.

    As a result of on-going internal and external assessment of the Acid Rain Program monitoring and reporting requirements, EPA, state environmental agencies, and utilities have identified areas of the Part 75 CEM regulations which would benefit from revision or clarification. Many of the suggested revisions will add increased flexibility to the utility industry in implementing and complying with the requirements of Part 75. Other revisions will clarify existing provisions in an effort to make the regulation more understandable. Still other revisions will provide increased quality assurance of the Acid Rain Program CEM data. The panel will present EPA`s current plans for a proposed rulemaking to incorporate the technical revisions to Part 75. The panel will briefly discuss EPA`s proposed revisions to some of the major issues and will respond to questions.

    NASA Astrophysics Data System (ADS)

    Clinton asked for $7.4 billion for the Environmental Protection Agency in FY 1996—a $138 million (2% increase) over FY 1995. EPA's hallmark, according to the agency, is “not growth, but change,” with its strategic plan The New Generation of Environmental Protection as its signpost. Ecosystem protection, environmental justice, pollution prevention, strong science and data, partnerships, environmental accountability, and reinventing EPA management are its top priorities.Clinton's budget asks for $1.56 billion for the Superfund program, a $131.7 million increase over fiscal year 1995. The budget has $77.3 million, a $7.3 million increase, for the Leaking Underground Storage Tank (LUST) program. EPA's water infrastructure program would take a $404 million hit in FY 1996, down to $2.37 billion.

    SciTech Connect

    Fort, D.J.; Stover, E.L.; Talley, J.M.; Copenhaver, M.B.

    1996-11-01

    As the result of Whole Effluent Toxicity (WET) test failures with Daphnia pulex, the US Environmental Protection Agency (EPA) required an industrial facility discharging approximately 5 million gallons per day (MGD) of recirculating cooling water obtained from a large freshwater river to conduct a Toxicity Reduction Evaluation (TRE) program. Under the terms of the National Pollutant Discharge Elimination System (NPDES) permit, the facility was required to conduct 48-hour acute toxicity tests with D. pulex and Pimephales promelas (fathead minnow). Although effluent toxicity to D. pulex was consistently observed, no toxicity was induced to the fathead minnow during the TRE program. The situation was further complicated by the fact that the recirculating cooling water was discharged back into the same river. The objectives of the TRE program were to investigate the causes of toxicity, locate potential sources of the suspected toxicant(s), and identify practicable toxicity reduction methodologies to be used. The TRE program approach and results from the associated studies are presented in this report, including a successful remedy for the WET problem.

  5. Computational toxicology as implemented by the U.S. EPA: providing high throughput decision support tools for screening and assessing chemical exposure, hazard and risk.

    PubMed

    Kavlock, Robert; Dix, David

    2010-02-01

    Computational toxicology is the application of mathematical and computer models to help assess chemical hazards and risks to human health and the environment. Supported by advances in informatics, high-throughput screening (HTS) technologies, and systems biology, the U.S. Environmental Protection Agency EPA is developing robust and flexible computational tools that can be applied to the thousands of chemicals in commerce, and contaminant mixtures found in air, water, and hazardous-waste sites. The Office of Research and Development (ORD) Computational Toxicology Research Program (CTRP) is composed of three main elements. The largest component is the National Center for Computational Toxicology (NCCT), which was established in 2005 to coordinate research on chemical screening and prioritization, informatics, and systems modeling. The second element consists of related activities in the National Health and Environmental Effects Research Laboratory (NHEERL) and the National Exposure Research Laboratory (NERL). The third and final component consists of academic centers working on various aspects of computational toxicology and funded by the U.S. EPA Science to Achieve Results (STAR) program. Together these elements form the key components in the implementation of both the initial strategy, A Framework for a Computational Toxicology Research Program (U.S. EPA, 2003), and the newly released The U.S. Environmental Protection Agency's Strategic Plan for Evaluating the Toxicity of Chemicals (U.S. EPA, 2009a). Key intramural projects of the CTRP include digitizing legacy toxicity testing information toxicity reference database (ToxRefDB), predicting toxicity (ToxCast) and exposure (ExpoCast), and creating virtual liver (v-Liver) and virtual embryo (v-Embryo) systems models. U.S. EPA-funded STAR centers are also providing bioinformatics, computational toxicology data and models, and developmental toxicity data and models. The models and underlying data are being made publicly

  6. The EPA's Study on the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources

    NASA Astrophysics Data System (ADS)

    Burden, Susan

    2013-03-01

    Natural gas plays a key role in our nation's clean energy future. The United States has vast reserves of natural gas that are commercially viable as a result of advances in horizontal drilling and hydraulic fracturing technologies, which enable greater access to gas in rock formations deep underground. These advances have spurred a significant increase in the production of both natural gas and oil across the country. However, as the use of hydraulic fracturing has increased, so have concerns about its potential human health and environmental impacts, especially for drinking water. In response to public concern, the US Congress requested that the US Environmental Protection Agency (EPA) conduct scientific research to examine the relationship between hydraulic fracturing and drinking water resources. In 2011, the EPA began research to assess the potential impacts of hydraulic fracturing on drinking water resources, if any, and to identify the driving factors that may affect the severity and frequency of such impacts. The study is organized around the five stages of the hydraulic fracturing water cycle, from water acquisition through the mixing of chemicals and the injection of fracturing fluid to post-fracturing treatment and/or disposal of wastewater. EPA scientists are using a transdisciplinary research approach involving laboratory studies, computer modeling, toxicity assessments, and case studies to answer research questions associated with each stage of the water cycle. This talk will provide an overview of the EPA's study, including a description of the hydraulic fracturing water cycle and a summary of the ongoing research projects.

    SciTech Connect

    Scofield, R.

    1984-01-01

    This report includes toxicological and regulatory evaluations performed in support of U.S. EPA regulation of toxic materials and hazardous wastes. The first section of the report describes evaluations which support: (a) the regulation of small-volume generators of hazardous wastes, (b) the regulation of hazardous wastes from pesticide manufacturing, and (c) the disposal of the herbicide, silvex. The second section describes the environmental fate, transport, and effect of glyphosate and dalapon. The third section deals with synthetic fuels, including evaluations of synfuel-product toxicity, uncontrolled air emissions, and particular focus on the toxicity of products from several indirect coal liquefaction processes including methanol synthesis, Fischer-Tropsch, Mobil M-Gasoline, and Lurgi gasification technologies. Three direct coal liquefaction processes were examined for product toxicity and air emissions: Solvent Refined Coal (I and II) and the Exxon Donor Solvent Process. Also described in the third section is an evaluation of environmental and health hazards associated with the use of synthetic fuels from indirect coal liquefaction, direct coal liquefaction, and shale oil. Finally, the fourth section discusses some problems associated with performing, on a contractual basis, scientific and technical evaluations in support of U.S. EPA regulatory and research decisions.

  12. Dietary reference intakes for DHA and EPA.

    PubMed

    Kris-Etherton, Penny M; Grieger, Jessica A; Etherton, Terry D

    2009-01-01

    Various organizations worldwide have made dietary recommendations for eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and fish intake that are primarily for coronary disease risk reduction and triglyceride (TG) lowering. Recommendations also have been made for DHA intake for pregnant women, infants, and vegetarians/vegans. A Dietary Reference Intake (DRI), specifically, an Adequate Intake (AI), has been set for alpha-linolenic acid (ALA) by the Institute of Medicine (IOM) of The National Academies. This amount is based on an intake that supports normal growth and neural development and results in no nutrient deficiency. Although there is no DRI for EPA and DHA, the National Academies have recommended that approximately 10% of the Acceptable Macronutrient Distribution Range (AMDR) for ALA can be consumed as EPA and/or DHA. This recommendation represents current mean intake for EPA and DHA in the United States ( approximately 100mg/day), which is much lower than what many groups worldwide are currently recommending. Global recommendations for long-chain omega-3 fatty acids underscore the pressing need to establish DRIs for DHA and EPA because DRIs are recognized as the "official" standard by which federal agencies issue dietary guidance or policy directives for the health and well-being of individuals in the United States and Canada. Because of the many health benefits of DHA and EPA, it is important and timely that the National Academies establish DRIs for the individual long-chain (20 carbons or greater) omega-3 fatty acids.

  16. U.S. EPA`s use of QSAR for new and existing chemical evaluations: Regulatory aspects

    SciTech Connect

    Zeeman, M.; Clements, R.G.; Nabholz, J.V.; Auer, C.M.

    1994-12-31

    As up front testing is not required, ecotoxicity or fate data are available for only about 5% of the 2,200 new chemicals/year submitted to EPA. The EPA`s Toxic Substances Control Act (TSCA) Inventory of existing chemicals currently lists about 72,000 chemicals. Most of existing chemicals also appear to have little or no ecotoxicity or fate data available. The EPA`s Office of Pollution Prevention and Toxics (OPPT) has developed and relies upon QSARs to estimate the ecotoxicity and fate of most of the new chemicals evaluated for ecological hazard and risk assessment. QSAR methods routinely result in ecotoxicity estimations of acute and sub/chronic toxicity to fish, aquatic invertebrates, and algae, and fate estimations of physical/chemical properties, degradation, and bioconcentration. GSAR methods were also used to screen the TSCA Inventory for the ecotoxicity of specific chemical classes of over 8,000 discrete chemicals. In the latter effort, seven major chemical classes made up almost 95% of these chemicals. From this QSAR analysis, about 10--20% or 15--18% of these chemicals, respectively, are expected to have high acute or high chronic toxicity to aquatic species. Estimates of ecotoxicity for > 8,000 discrete organics enhances prioritization of chemicals on the TSCA Inventory and helps focus EPA/OPPT regulatory efforts upon the potentially most toxic substances.

    The Clean Air Power Initiative (CAPI) is a multi-stakeholder project intended to improve air pollution control efforts involving the power generating industry. This paper documents the progress made in the first year of the initiative, which included a number of meetings with interested stakeholders and development and analysis of alternative approaches for more efficient and effective pollution control. The project`s goal is to develop an integrated regulatory strategy or three major pollutants emitted from electric power generators; namely, sulfur dioxide, nitrogen oxides, and, potentially, mercury. Major reductions in these pollutants are expected to be needed to reduce the detrimental health effects of ground-level ozone, fine particles, and hazardous air pollutants and reduce the environmental effects of acidification, eutrophication, ecosystem, crop, and materials damage, and regional haze. The Clean Air Power Initiative has considered, where feasible, new approaches to pollution control that recognize the long-range transport of many air pollutants and the economic benefits of emissions trading. The project was initiated by EPA`s Assistant Administrator for Air and Radiation in 1995. As individual companies develop and implement strategies to participate in more competitive power markets, they could benefit from greater certainty in being able to plan for and reduce costs of future environmental regulations. The EPA is interested in reinventing its regulatory approach to reduce the number, administrative complexity, and cost of its requirements while improving the likelihood of achieving environmental results.

  20. EPA Remote Sensing Information Gateway

    The Remote Sensing Information Gateway was developed by the U.S. Environmental Protection Agency (EPA) to assist researchers in easily obtaining and combining a variety of environmental datasets related to air quality research. Current datasets available include, but are not limited to surface PM2.5 and O3 data, satellite derived aerosol optical depth , and 3-dimensional output from U.S. EPA's Models 3/Community Multi-scale Air Quality (CMAQ) modeling system. The presentation will include a demonstration that illustrates several scenarios of how researchers use the tool to help them visualize and obtain data for their work; with a particular focus on episode analysis related to biomass burning impacts on air quality. The presentation will provide an overview on how RSIG works and how the code has been—and can be—adapted for other projects. One example is the Virtual Estuary, which focuses on automating the retrieval and pre-processing of a variety of data needed for estuarine research. RSIG’s source codes are freely available to researchers with permission from the EPA principal investigator, Dr. Jim Szykman. RSIG is available to the community and can be accessed online at http://www.epa.gov/rsig. Once the JAVA policy file is configured on your computer you can run the RSIG applet on your computer and connect to the RSIG server to visualize and retrieve available data sets. The applet allows the user to specify the temporal/spatial areas of interest, and the types of data to retrieve. The applet then communicates with RSIG subsetter codes located on the data owners’ remote servers; the subsetter codes assemble and transfer via ordinary Internet protocols only the specified data to the researcher’s computer. This is much faster than the usual method of transferring large files via FTP and greatly reduces network traffic. The RSIG applet then visualizes the transferred data on a latitude-longitude map, automatically locating the data in the correct

  19. Electrostatic Plasma Accelerator (EPA)

    NASA Technical Reports Server (NTRS)

    Brophy, John R.; Aston, Graeme

    1989-01-01

    The Electrostatic Plasma Accelerator (EPA) is a thruster concept which promises specific impulse levels between low power arcjets and those of the ion engine while retaining the relative simplicity of the arcjet. The EPA thruster produces thrust through the electrostatic acceleration of a moderately dense plasma. No accelerating electrodes are used and the specific impulse is a direct function of the applied discharge voltage and the propellant atomic mass. The goal of the present program is to demonstrate feasibility of the EPA thruster concept through experimental and theoretical investigations of the EPA acceleration mechanism and discharge chamber performance. Experimental investigations will include operating the test bed ion (TBI) engine as an EPA thruster and parametrically varying the thruster geometry and operating conditions to quantify the electrostatic plasma acceleration effect. The theoretical investigations will include the development of a discharge chamber model which describes the relationships between the engine size, plasma properties, and overall performance. For the EPA thruster to be a viable propulsion concept, overall thruster efficiencies approaching 30% with specific impulses approaching 1000 s must be achieved.

    This bibliography contains citations concerning the Toxic Release Inventory (TRI) database issued by the Environmental Protection Agency (EPA). The TRI database was begun by EPA in response to Section 313 of the Emergency Planning and Community Right-to-Know Act of the Superfund Amendments and Reauthorization Act of 1986, which required EPA to establish an inventory of routine toxic chemical emissions from certain facilities. There are over 300 chemicals and categories on these lists. The reporting requirement applies to owners and operators of manufacturing facilities that employ 10 or more full-time employees and that manufacture, process, or otherwise use a tested toxic chemical in excess of specified threshold quantities. The data file is contained on diskettes in dBASE III format or LOTUS 1-2-3 format available from the National Technical Information Service (NTIS).

    1998-12-31

    In September 1997, the US Department of Energy (DOE) and US Environmental Protection Agency (EPA) co-sponsored a demonstration of several multimetal continuous emission monitors (CEMs). The demonstration, performed at the EPA National Risk Management Research Laboratory, Air Pollution Prevention and Control Division`s combustion laboratory in Research Triangle Park, NC, involved the side-by-side testing of seven multimetal CEMs at various stages of commercialization. A series of tests were performed to compare results from the multimetal CEMs to Method 0060, the EPA reference method (RM) for metals emissions measurements, using the relative accuracy test audit (RATA) protocol. The EPA operated the test facility and performed the RM sampling, and each multimetal CEM was operated by the instrument`s respective developer. To accomplish these tests, an aqueous solution of six toxic metals (arsenic, beryllium, cadmium, chromium, lead, and mercury), along with flyash from a coal-fired utility boiler, was injected into the afterburner of the EPAs rotary kiln incinerator simulator facility to generate a combustor flue gas with realistic post-flue gas cleaning system particulate loadings and target metals concentrations of approximately 15 and 75 {micro}g/m{sup 3}, which constituted the low and high concentration test conditions. The multimetal CEMs that participated in the test included two laser-induced breakdown spectroscopy (LIBS) systems, two inductively coupled plasma (ICP) systems, a spark-induced breakdown spectroscopy (SIBS) system, a hazardous element sampling train with X-ray fluorescence (HEST/XRF), and a microwave plasma system. Ten RM-CEM sample pairs were taken at both the low and high concentration test conditions, and the relative accuracies of the multimetal CEMs were calculated. This test provided performance data that will be used to assess the current state of the art in multimetal CEMs.

    1982-09-01

    As stated at the beginning of this paper conclusions reached thus far cannot be discussed in this paper. However, a great deal of information is available for examination.EPA displayed its ability to coordinate widely separated laboratories, both Federal and private, into a smooth working team in a very short period of time. A very comprehensive study plan was also developed and implemented quickly. EPA was fortunate to have already had GCA under contract when the emergency arose. In no small part the success of the field effort was due to the managerial and technical abilities of the GCA team.Within a period of 6 weeks a plan was developed, a prime contractor retained, subcontractors hired, and field activities begun. Within a period of 3 months in excess of 8600 field samples were collected and over 12,000 field and QC samples were analyzed. During this same period 2 major data systems were developed, debugged, and placed into operation.In short this EPA project was probably the most comprehensive multimedia field project ever attempted by EPA and certainly the data is being subjected to the most strenuous quality control measures ever imposed by this Agency. The entire program is presently under peer review and the results are being prepared for publication by EPA Headquarters. PMID:24264296

  20. 2008 Toxic Chemical Release Inventory 2008 Toxic Chemical Release Inventory Community Right-to-Know Act of 1986, Title III, Section 313

    SciTech Connect

    Ecology and Air Quality Group

    2009-10-01

    For reporting year 2008, Los Alamos National Laboratory (LANL) submitted a Form R report for lead as required under the Emergency Planning and Community Right-to- Know Act (EPCRA) Section 313. No other EPCRA Section 313 chemicals were used in 2008 above the reportable thresholds. This document was prepared to provide a description of the evaluation of EPCRA Section 313 chemical use and threshold determinations for LANL for calendar year 2008, as well as to provide background information about data included on the Form R reports. Section 313 of EPCRA specifically requires facilities to submit a Toxic Chemical Release Inventory Report (Form R) to the U.S. Environmental Protection Agency (EPA) and state agencies if the owners and operators manufacture, process, or otherwise use any of the listed toxic chemicals above listed threshold quantities. EPA compiles this data in the Toxic Release Inventory database. Form R reports for each chemical over threshold quantities must be submitted on or before July 1 each year and must cover activities that occurred at the facility during the previous year. In 1999, EPA promulgated a final rule on persistent bioaccumulative toxics (PBTs). This rule added several chemicals to the EPCRA Section 313 list of toxic chemicals and established lower reporting thresholds for these and other PBT chemicals that were already reportable. These lower thresholds became applicable in reporting year 2000. In 2001, EPA expanded the PBT rule to include a lower reporting threshold for lead and lead compounds. Facilities that manufacture, process, or otherwise use more than 100 lb of lead or lead compounds must submit a Form R.

  1. Mixed welcome: Beware of some limitations in EPA`s audit policy

    SciTech Connect

    Hill, M.

    1996-03-01

    The US Environmental Protection Agency`s Final Policy on Environmental Audits became effective January 22. The policy provides guidance on penalty mitigation for voluntary disclosures of environmental violations, and replaces EPA`s March 30, 1995, Interim Policy. In the Final Policy, EPA gives three basic incentives for companies to conduct audits: full or partial waiver of penalties for violations discovered; no recommendations for criminal prosecution; and no routine requests for environmental audits. To achieve these benefits, however, the policy demands adherence to nine separate conditions. Moreover, EPA remains opposed to providing immunity or recognizing privilege--even when created by state statutes--with respect to environmental audits. The policy also provides no protections to individual managers or employees. Finally, the agency has retained broad discretion to deviate from the policy on a case-by-case basis; thus, the policy provides little certainty to industry. Although the policy is a welcome step in the right direction, companies should be aware of the many limitations in the policy as they consider implementing environmental audit or due-diligence systems.

  7. Aquatic toxicity variability for fresh- and saltwater species in refinery wastewater effluent

    SciTech Connect

    Bleckmann, C.A.; Rabe, B.; Edgmon, S.J.; Fillingame, D.

    1995-07-01

    The US Environmental Protection Agency (EPA) has established test requirements for toxicity reduction or toxicity identification evaluations (TR/TIE) of wastewater effluents. Interpretations of test results are complicated by factors other than toxicity when essentially freshwater wastewaters flow into estuaries and the effluent permit requires marine organisms for testing. This paper reports the results of an investigation of potential freshwater surrogate species, and Microtox{reg_sign}, for use in such a TIE. Of the five species tested, mysid shrimp were found to be most sensitive to unidentified toxicants in petroleum refinery wastewater. No strong correlations of this sensitivity to that of other organisms, or to several wastewater constitutents, were identified. The two marine species specified in the effluent permit were more sensitive to the toxicants that were the freshwater species.

  12. Air toxics provisions of the Clean Air Act: Potential impacts on energy

    SciTech Connect

    Hootman, H.A.; Vernet, J.E.

    1991-11-01

    This report provides an overview of the provisions of the Clean Air Act and its Amendments of 1990 that identify hazardous air pollutant (HAP) emissions and addresses their regulation by the US Environmental Protection Agency (EPA). It defines the major energy sector sources of these HAPs that would be affected by the regulations. Attention is focused on regulations that would cover coke oven emissions; chromium emission from industrial cooling towers and the electroplating process; HAP emissions from tank vessels, asbestos-related activities, organic solvent use, and ethylene oxide sterilization; and emissions of air toxics from municipal waste combustors. The possible implications of Title III regulations for the coal, natural gas, petroleum, uranium, and electric utility industries are examined. The report discusses five major databases of HAP emissions: (1) TRI (EPA`s Toxic Release Inventory); (2) PISCES (Power Plant Integrated Systems: Chemical Emissions Studies developed by the Electric Power Research Institute); (3) 1985 Emissions Inventory on volatile organic compounds (used for the National Acid Precipitation Assessment Program); (4) Particulate Matter Species Manual (EPA); and (5) Toxics Emission Inventory (National Aeronautics and Space Administration). It also offers information on emission control technologies for municipal waste combustors.

    SciTech Connect

    Denton, D.; Chapman, G.; Fulk, F.

    1995-12-31

    The US Environmental Protection Agency`s test method manuals recommend reference toxicant test be performed to determine test sensitivity and precision within a test and among tests over time. The levels of intra and interlaboratory precision with two reference toxicants (zinc and copper) were examined with six marine test species (Macrocystis pyrifera, Haliotis rufescens, Strongylocentrotus purpuratus, Dendraster excentricus, Mytilus spp., and Menidia beryllina) and with two freshwater test species (Ceriodaphnia dubia and Pimephales promelas). Data from the EPA`s Reference Toxicant Database were used in the analysis. Data was used if the tests met the specified test acceptability criteria. The test sensitivity was examined by calculation of the minimum significant difference (e.g. MSD) and will be discussed. Results were compared to the national final chronic value (FCV) for copper and zinc. Greater than 99% of the EC25 values were above the FCV for copper with Strongylocentrotus purpuratus, Dendraster excentricus and Macrocystis pyrifera. However, greater than 99% of the EC25 values were below the FCV for zinc with Haliotis rufescens.

  15. Use of genetic toxicology data in U.S. EPA risk assessment: the mercury study report as an example.

    PubMed Central

    Schoeny, R

    1996-01-01

    Assessment of human health risks of environmental agents has often been limited to consideration of the potential for the agent to cause cancer or general systemic toxicity after long-term exposure. The U.S. Environmental Protection Agency (U.S. EPA) is increasingly moving toward the development of integrated assessments, which consider all potential health end points including developmental toxicity, neurotoxicity, immunotoxicity, reproductive effects, and germ cell mutagenicity. The U.S. EPA has a responsibility to assess risks to nonhuman species or ecosystems when appropriate data are available. An example of a recent integrated human health and ecological risk assessment can be found in the U.S. EPA Mercury Study Report to Congress. This report covers the following topics in separate volumes: an inventory of anthropogenic mercury emissions in the United States; an exposure assessment using measured and predicted values and including indirect dietary exposure; an evaluation of human health risks; an assessment of ecologic risk wherein water criteria are presented for several wildlife species; an overall integrated characterization of human and nonhuman risk; and a discussion of risk management considerations. In the evaluation of human health risk, genetic toxicology data were considered for three forms of mercury: elemental, inorganic (divalent), and methylmercury. These data were used in judgments of two types of potential health effects (carcinogenicity and germ cell mutagenicity). In assessment of potential carcinogenicity of inorganic and methylmercury, genetic toxicity data were key. Data for clastogenicity in the absence of mutagenicity supported the characterization of inorganic and methylmercury as materials that produce carcinogenic effects only at high, toxic doses. The evidence for clastogenicity, coupled with information on metabolism and distribution, resulted in a judgment of a moderate degree of concern (or weight of evidence) that inorganic

  16. European Chemicals Agency dossier submissions as an experimental data source: refinement of a fish toxicity model for predicting acute LC50 values.

    PubMed

    2015-02-01

    As a result of the stringent data requirements of the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation, a vast amount of ecotoxicological data has become available through the dissemination portal of the European Chemicals Agency (ECHA). As of April 2014, the database contained 12,439 unique substances from 47,909 dossiers. This vast database could be used to refine existing, or to create new, non-testing methods, such as quantitative structure-activity relationships (QSARs). Acute fish toxicity data were mined from the ECHA database using the eChemPortal; after filtering for single organic substances, 1159 experimental data points remained, representing 564 compounds. To evaluate the quality and accessibility of this data, the authors used the data to refine and improve an existing QSAR. The reliability of the data submitted to the ECHA database, as well as the effectiveness of the Klimisch scoring system, were assessed by comparing the refined QSAR with established QSAR benchmarks. The model developed meets all Organisation for Economic Co-operation and Development principles, has strong internal (leave-one-out internally cross-validated correlation coefficient [Q(2)(LOO)] = 0.91) and external (external coefficient of determination (predicted vs experimental [test set])) validation statistics, and can provide reliable fish median lethal concentration (LC50) predictions for non-polar narcotics. Although some issues with dossier misinformation were discovered, it was found that the ECHA dissemination portal is a valuable and reliable data source. When queried using the eChemPortal, chemical dossiers containing reliable data could be found quickly. The ECHA dissemination portal holds great potential for future QSAR development and improvement, such as updating QSARs within the Ecological Structure-Activity Relationships (ECOSAR) program.
