The Agency for Toxic Substances and Disease Registry (ATSDR) is a federal public health agency of the U.S. Department of Health and Human Services. ATSDR protects communities from harmful health effects related to exposure to natural and man-made hazardous substances. We do this by responding to environmental health emergencies; investigating emerging environmental health threats; conducting research on the health impacts of hazardous waste sites; and building capabilities of and providing actionable guidance to state and local health partners.
This site provides information about toxic substances and how they affect our health including: characteristics, exposure risks, associated health effects, related CDC and ATSDR health studies and assessments.
The ECOTOXicology database (ECOTOX) is a source for locating single chemical toxicity data for aquatic life, terrestrial plants and wildlife. ECOTOX was created and is maintained by the U.S.EPA
The Consumer Product Information Database (cpid) contains health effects information for products used in the home and in some commercial/institutional settings that contain chemicals. (Formerly known as Household Products Database)
