BACKGROUND.

EPA’s Office of Research and Development has developed a draft Toxicological Review of Benzo[a]pyrene (September 2014), which updates a 1987 assessment of the toxicity of benzo[a]pyrene posted to the IRIS database. The 2014 draft assessment contains a qualitative characterization of the hazards for benzo[a]pyrene, including a cancer descriptor of the chemical’s human carcinogenic potential, cancer risk estimates for oral, inhalation and dermal exposure, and noncancer toxicity values for chronic oral (reference dose) and inhalation (reference concentration) exposure. The draft assessment also includes the IRIS Program’s first dermal slope factor. ORD has requested SAB peer review of its September 2014 draft toxicological review for benzo[a]pyrene.
