BENZO[A]PYRENE

Benzo[a]pyrene (B[a]P) is one of the polycyclic aromatic hydrocarbon (PAH) compounds. Because it is formed when petrol, rubbish, or any animal or plant material is burned, it is usually found in smoke and soot. Benzo[ a]pyrene is also found in the coal tar pitch that is used to join electrical parts together and in creosote.
