Ecological Risk Assessment Tools

Online databases and other sources of information used in Ecological Risk Assessments:

These links provide information that may be useful in preparing an ecological risk assessment (ERA). The information includes life-history data, tools to assist in developing ERAs, modelling information, and other resources providing information on the processes and procedures for ecological risk assessment. Information on various screening benchmarks can be found on the Screening Numbers page

U.S. EPA Region 5 makes no promise that the information presented therein is correct. Always be sure to consult with a regional Superfund ecologist to verify that the use of any and all toxicity values and life history information is acceptable. References and links via this webpage are not endorsements of the information on those websites.

Wildlife Exposure Factors (WEF) - Life history information of birds, mammals, reptiles and amphibians

U.S. EPA ECOTOX Database system
The ECOTOXicology database is a source for locating single chemical toxicity data for aquatic life, terrestrial plants and wildlife. ECOTOX integrates three toxicology effects databases: AQUIRE (aquatic life), PHYTOTOX (terrestrial plants), and TERRETOX (terrestrial wildlife). These databases were created by the U.S. EPA, Office of Research and Development (ORD), and the National Health and Environmental Effects Research Laboratory (NHEERL), Mid-Continent Ecology Division.

AQUATOX is a simulation model for aquatic systems. AQUATOX predicts the fate of various pollutants, such as nutrients and organic chemicals, and their effects on the ecosystem, including fish, invertebrates, and aquatic plants. AQUATOX is a valuable tool for ecologists, biologists, water quality modelers, and anyone involved in performing ecological risk assessments for aquatic ecosystems.

Spatial Analysis and Decision Assistant Software (SADA):Exit EPA Disclaimer
Software developed to assist in analyzing the spatial distribution of contaminants at sites. It also can calculate Hazard Quotients and assist in sampling plans.
