The Integrated Risk Information System (IRIS) is a U.S. Environmental Protection Agency (EPA) database that contains information on human health effects that may result from exposure to chemical substances in the environment. IRIS is maintained by EPA’s Office of Research and Development.
The IRIS process consists of development of a draft Toxicological Review for the chemical, internal and external scientific reviews of the draft document, EPA responses to review comments, and development and posting on the IRIS web site. IRISTrack is available to see the progress of the chemicals currently under review.
