IRIS
IRIS Home | 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.
