The National Center for Environmental Assessment (NCEA) in the EPA’s Office of Research and Development (ORD) develops toxicological reviews/assessments for various chemicals for IRIS. NCEA is developing a draft IRIS assessment for Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and has asked the SAB to peer review the draft document. The draft will be a reassessment of RDX. NCEA’s draft Toxicological Review of Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) currently posted to the IRIS database includes an oral reference dose (RfD) (posted in 1988), and a cancer descriptor and oral cancer slope factor (posted in 1990). Epidemiological data, experimental animal data, and other relevant data from studies of the noncancer and cancer effects of RDX are being evaluated in this reassessment. The reassessment is expected to include an updated RfD and oral cancer assessment.
