ABSTRACT
The National Database on Body Burden of Toxic Chemicals is composed of two major files, Chemicals Identified in Human Biological Media and Chemicals Identified in Feral and Food Animals, which were established in 1978 and 1980, respectively, under the aegis of the Interagency Collaborative Group on Environmental Carcinogenesis, National Cancer Institute (NCI). The program to develop and maintain the data base is funded through the NCI/Environmental Protection Agency (EPA) Collaborative Program and an interagency agreement between the EPA and the Department of Energy (DOE). The work is conducted under the management of the Office of Toxic Substances (OTS), EPA, by Science Applications International Corporation (SAIC).
