This annual evaluation activity fulfills the conditions of CERCLA section 104 (i), as ammended, which requires ATSDR and EPA to revise the priority list of hazardous substances (N=275) periodically to include additional hazardous substances.
Each chemical is identified with a Rank Number and includes an ATSDR Public Health Statement.
The Public Health Statements were prepared by the ATSDR Division of Toxicology. They provide general information on the properties of the chemical and answer many health concerns that are voiced by community groups.
