The EFDB aids in identifying persistent chemical classes, as well as physical or chemical properties that may correlate to particular behavior in the environment. The EFDB is comprised of several interrelated files, including DATALOG, CHEMFATE, BIOLOG, and BIODEG. These databases share a CAS# file containing over 20,000 chemicals with a preferred name and formula, and a bibliographic file containing full references on over 36,000 articles cited. They are under constant expansion, and may be accessed on the EFDB webpage. Quarterly, snapshots of the databases are made available in a Microsoft Windows version and on this web site.

By Congressional mandate, the Agency for Toxic Substances and Disease Registry (ATSDR) produces "toxicological profiles" for hazardous substances found at National Priorities List (NPL) sites. These hazardous substances are ranked based on frequency of occurrence at NPL sites, toxicity, and potential for human exposure. Toxicological profiles are developed from a priority list of 275 substances. ATSDR also prepares toxicological profiles for the Department of Defense (DOD) and the Department of Energy (DOE) on substances related to federal sites. So far, 296 toxicological profiles have been published or are under development as “finals” or “drafts for public comment”; 281 profiles were published as finals; 130 profiles have been updated. Currently, 7 profiles are being revised based on public comments received. These profiles cover more than 250 substances.
