The ECOTOXicology Knowledgebase (ECOTOX) is a comprehensive, publicly available knowledgebase providing single chemical environmental toxicity data on aquatic life, terrestrial plants and wildlife. The ECOTOX database (as of March 2019) contains data for 11,695 chemicals and 12,7...

Quality Criteria for the Protection of Aquatic Organisms and Their Uses specifies Minimum Data Requirements (MDRs) for developing national Aquatic Life Ambient Water Quality Criteria (WQC) under Section 304(a) (l) of the Clean Water Act. MDRs define minimum toxicity test data, by...

The ECOTOXicology Knowledgebase (ECOTOX, http://www.epa.gov/ecotox/), is a comprehensive, curated database that summarizes toxicity data fromsingle-chemical exposure studies to aquatic life, terrestrial plants, and wildlife. For over 30 years, ECOTOX has provided ecologically-rel...

Toxicity tests used in regulatory programs to develop ambient water quality criteria (AWQC) or Environmental Quality Standards (EQS) have historically consisted of single organism assays of either 48-96 hr (acute) or 7-28-day (chronic or short term chronic) duration. Resulting da...

Little information is available on the fate and effects of nanomaterials in the marine environment; however, to develop informed regulations for these materials, this type of information is essential. In 2010, a research program was initiated by the U.S. EPA&rsquo;s Office of Re...

Presentation to be given at the Annual UNC Water Microbiology Meeting. Fecal Pollution is a Worldwide Problem. Fecal microbes are a common biological contaminant in surface waters worldwide. EPA Responsibilities are to protect and restore waters for recreational use, Clean Water ...

Abstract Anthropogenic chemicals have been proposed as potential markers of human fecal contamination in recreational water. However, to date, there are no published studies describing their relationships with illness risks. Using a cohort of swimmers at seven U.S. beaches, we e...

Freshwater mussels, one of the most imperiled groups of animals in the world, are generally underrepresented in toxicity databases used for the development of ambient water quality criteria and other environmental guidance values. Acute 96-h toxicity tests were conducted to evalu...

A methodology for developing remediation goals for sites with contaminated sediments is provided. The remediation goals are based upon the concentrations of chemicals in the sediment interstitial water measured using the passive sampling technique. The passive sampling technique ...

Evaluating the potential human health and/or ecological risks associated with exposures to complex chemical mixtures in the ambient environment is one of the central challenges of chemical safety assessment and environmental protection. There is a need for approaches that can he...
