A-Z List of Substances

The substances in IRIS are listed in order alphabetically by the substance name. You can click on the Alphabetical letter corresponding to the chemicals beginning with that letter to list the relevant substances, or use your browser's "Find" command to search for a substance name or Chemical Abstracts Service Registry Number (CASRN).

The IRIS Program does not currently develop updated assessments for registered pesticides unless the registered pesticides also have non-pesticide uses. The IRIS user should consult OPP Reregistration Eligibility Decision (RED) documents prepared by the Office of Pesticide Programs for additional health assessment information (see link provided in the OPP Reregistration Eligibility Decision (RED) column below).

* Refers to the most recent statement of or change to a toxicity value [RfD, RfC, slope factor or unit risk], or most recent significant statement of or change to the basis or justification for the conclusions in the assessment. This column is provided for the convenience of the IRIS user. For specific information, see the Revision History for each substance.
