The draft Toxicological Review of Bromobenzene provides scientific support and rationale for the hazard and dose-response assessment pertaining to subchronic and chronic exposure to bromobenzene. Bromobenzene is a heavy, colorless liquid with a pungent odor and is also known as monobromobenzene and phenyl bromide. Bromobenzene is used as an additive to motor oils, as a crystallizing solvent, and in the production of the synthetic intermediate phenyl magnesium bromide. Release of bromobenzene to the environment may occur during its production and the production of phenyl magnesium bromide as well as in its use as a solvent and as an additive in motor oil. Bromobenzene can be formed in small quantities during water chlorination. Bromobenzene is on the Office of Water's Contaminant Candidate List and is found at hazardous waste and Superfund sites. This assessment contains the derivation of reference doses for two durations of exposure (subchronic and chronic). EPA is also putting forth for external review the statement that data are inadequate for an assessment of the human carcinogenic potential of bromobenzene.
|2003||The bromobenzene IRIS assessment was initiated in 2003. Bromobenzene was nominated for assessment by the IRIS Program because it appears on the Office of Water’s Contaminant Candidate List (CCL). It has also been detected at Superfund sites. An assessment for bromobenzene is not currently on IRIS.|
|Jun 2007||EPA released the external review draft for the Toxicological Review of Bromobenzene.|
|Aug 2007||An external peer review panel workshop was hosted by an independent contractor to review the draft document.|
|Sep 2009||EPA released the Final Toxicological Review (PDF) (123 pp, 764K) and accompanying Summary for Bromobenzene to the IRIS Web site.|
