ATSDR is directed by congressional mandate to perform specific functions concerning the effect on public health of hazardous substances in the environment. These functions include public health assessments of waste sites, health consultations concerning specific hazardous substances, health surveillance and registries, response to emergency releases of hazardous substances, applied research in support of public health assessments, information development and dissemination, and education and training concerning hazardous substances.
When harmful chemical exposure happens, the Agency for Toxic Substances and Disease Registry (ATSDR) is ready to respond. Our top priority is to protect people from harmful chemical exposures. ATSDR has helped people in more than 900 communities all over the country.
