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.
