Identifier: CID 2336

Polycyclic aromatic hydrocarbon with five connected six-membered rings
Benzo[a]pyrene occurs in fossil fuels and is a product of incomplete combustion of organic material. It is found, e.g., in automobile and industrial exhausts, in tobacco smoke and charbroiled meat.
Its volatility is low and in the atmosphere it is mostly particle bound. It enters soils and waters through dry and wet deposition.
Benzo[a]pyrene is toxic and has a high potential for bioaccumulation. In animal experiments it is carcinogenic and is suspected to be carcinogenic also to humans. Furthermore, it is classified as mutagenic, teratogenic and reproductive toxic.
Benzo[a]pyrene is one of 16 PAHs which were included in the U.S. EPA-list of Priority Pollutants and is on the EU-list of PAH recommended for monitoring.
It is frequently used as indicator for PAH-contamination.
