Benzo(a)pyrene
Benzo(a)pyrene [B(a)P] is a polycyclic aromatic hydrocarbon (PAH) having five aromatic rings in a fused, honeycomb-like structure. Its formula and molecular weight are C20H12 and 252.30, respectively. It is a naturally occurring and man-made organic compound formed along with other PAH in incomplete combustion reactions, including the burning of fossil fuels , motor vehicle exhaust, wood products, and cigarettes. It is classified as a known human carcinogen by the EPA, and is considered to be one of the primary carcinogens in tobacco smoke . Synthesized in 1933, it was the first carcinogen isolated from coal tar and often serves as a surrogate compound for modeling PAHs.
