IRIS Critical Effect Search Results

Searches using filters for organ/system affected are limited to effects (or tumor sites) used to derive the RfD, RfC, oral slope factor, or inhalation unit risk. Other effects associated with chemicals in the IRIS database that were not used as the basis for a toxicity value are not searchable with organ/system filters. IRIS Advanced Search searches only final IRIS assessments; to look for information on draft assessments, see Quick Check: Assessments in Development.
