IRIS is a toxicology data file on the National Library of Medicine's (NLM) Toxicology Data Network (TOXNET®). It contains data in support of human health risk assessment. It is compiled by the U.S. Environmental Protection Agency (EPA) and contains over 500 chemical records. IRIS data, focusing on hazard identification and dose-response assessment, is reviewed by work groups of EPA scientists and represents EPA consensus. Among the key data provided in IRIS are EPA carcinogen classifications, unit risks, slope factors, oral reference doses, and inhalation reference concentrations.
IRIS is accessible, free of charge, via TOXNET at: http://toxnet.nlm.nih.gov
Users can search by chemical or other name, chemical name fragment, Chemical Abstracts Service Registry Number (RN), and/or subject terms. Search results can easily be viewed, printed or downloaded.

Users can easily conduct their IRIS search strategy against other databases: Hazardous Substances Data Bank®, Chemical Carcinogenesis Research Information System, GENE-TOX, TOXLINE®, ChemIDplus®, and ITER®.
