The Agency for Toxic Substances and Disease Registry (ATSDR) is an agency of the U.S. Department of Health and Human Services (HHS).
  As mandated by the federal superfund law, the agency assesses health risks from hazardous waste sites on the EPA's National Priorities List.
 ATSDR determines if additional health studies are needed at these sites, provides health advisories and publishes toxicological profiles on chemicals found at hazardous waste sites.

  ATSDR also maintains exposure registries of people exposed to certain substances.
