Abstract
Benzo[a]pyrene is a five-ring polycyclic aromatic hydrocarbon that is relatively insoluble in water and has low volatility. It is ubiquitous in the environment primarily as a result of incomplete combustion emissions. Natural sources of benzo[a]pyrene include forest fires and volcanoes, and anthropogenic sources include stoves/furnaces burning fossil fuels (especially wood and coal), motor vehicle exhaust, and various industrial combustion processes. Major sources of occupational exposure involve production of aluminum, coke, graphite and silicon carbide, as well as coal tar distillation. Major sources of non-occupational exposure involve tobacco products and diet (e.g., barbequed or charred meats).
In September 2014, EPA submitted the draft IRIS assessment of benzo[a]pyrene (see downloads) to the agency’s Science Advisory Board (SAB) for peer review and comments. EPA had previously released a draft of the assessment for public comment (see related links), held a public meeting about the draft, and then revised it based on the comments received. The SAB Chemical Assessment Advisory Committee (CAAC), augmented for the review of the draft IRIS assessment of benzo[a]pyrene (CAAC-benzo[a]pyrene panel), will review this draft assessment. Details about the CAAC-Benzo[a]pyrene panel, meeting dates, and times will be announced in a Federal Register Notice released by the SAB. The notice will provide information on how the public can participate in the BaP external peer review meetings, as well as instructions about how to provide comments to the SAB. Additional information on the SAB-CAAC review of benzo[a]pyrene is on the SAB website.
