The European Union Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM) Strategy Document on Toxicokinetics (TK) outlines strategies to enable prediction of systemic toxicity by applying new approach methodologies (NAM). The central feature of the strategy focuses...

The U.S. Environmental Protection Agency (EPA) Engineering Issue Papers (EIPs) are a series of technology transfer documents that summarize the latest information on selected waste treatment and site remediation technologies and related issues. The information is presented in a c...

This report presents the results of twenty competitively funded Science-To-Achieve-Results (STAR) grants in EPA's Environmental Public Health Indicators (EPHI) research program. The grantsdirectly supported health interventions, informed policy and decision-making, and improved t...

This report by the U.S. Environmental Protection Agency’s (EPA’s) Homeland Security Research Program (HSRP) strives to provide expertise and products that can be widely used to prevent, prepare for, and recover from public health and environmental emergencies arising from terrori...

This report chronicles the study undertaken to evaluate the decontamination efficacy of diperadipic acid, under application conditions that were found to be effective for pH-adjusted bleach (a common sporicidal liquid). The results showed that diperadipic acid demonstrated >6 Lo...

Report—Exposure estimates were performed to rank the various livestock carcass management options relative to one another for a hypothetical site and mortality scenario from a potential biological incident. Assessment included an ordinal scale ranking (ranking of individual condi...

This update includes new information and factors needed to assess exposure to environmental agents that occur from ingestion of meats, dairy products, and fats that has become available since the <em>Exposure Factors Handbook: 2011 Edition</em> was released. The recommended value...

This update includes new information and factors on the intake of grain products that has become available since the <em>Exposure Factors Handbook: 2011 Edition</em> was released. The recommended values for use in risk assessment have been revised, as needed, to reflect this new ...

This update includes new information and factors on building characteristics that affect exposure in an indoor environment that has become available since the <em>Exposure Factors Handbook: 2011 Edition</em> was released. The recommended values have been revised, as needed, to re...

Report--Provides information and a screening tool to perform an exposure assessment for emerging pathogens in wastewater systems

In the complex arena of sustainability, where the costs of failure can be high and stakeholders have multiple and sometimes conflicting interests, communities need measurement tools to characterize their current state, develop meaningful goals and quantifiable objectives for the ...

This SHC 2.61.1 Output report (Practical Strategies for Assessing FEGS in Community Decision Making) describes the U.S. EPA&rsquo;s Office of Research and Development&rsquo;s (ORD) research to incorporate the sustainability of final ecosystem goods and services (FEGS) production ...

The City of Dover, Delaware, and Kent County are seeking to redevelop a vacant and formerly contaminated property, or brownfield, to spur revitalization in the Downtown Dover area. Given a desire to increase food access in and around Dover, local and state officials sought assist...

The GCSolar.NET program will allow the user to view, manipulate, or run the GCSolar.NET modeling simulation for photolysis of contaminants in water. This guide focuses on chemical contaminants, but the same steps can be used to compute values for biological contaminants.
