  1. Benzo[a]pyrene belongs to the class of polycyclic aromatic hydrocarbons (PAHs).
  2. It is produced during incomplete combustion or pyrolysis of organic material and found in nature from the eruption of volcanoes and forest fires. Man-made benzo[a]pyrene is formed by burning plants, wood, coal, and operating cars, trucks and other vehicles. It is also present in some foods (e.g. smoked and barbecued meals), in a few pharmaceutical products, and in tobacco smoke. It is considered as potent mutagen and carcinogen. Benzo[a]pyrene containing extender oil is used for the rubber/plastic production to achieve the desired elasticity at a cheaper price. Benzo[a]pyrene containing coal tar pitch is used in many paints or coatings as corrosion protection coats, such as hydraulic equipment, pipework, steel pilings in ports, vessels, and sealcoat products. Benzo[a]pyrene can be used as wood-preservatives to prevent wood parasites and the wood from drying out.

  1. Benzopyrene is a polyaromatic hydrocarbon (PAH) found in coal tar. Benzopyrene is a known carcinogen. The metbolism of Benzopyrene results in diol epoxides that react and bind to DNA forming adducts which in turns leads to mutations and eventually cancer.
  2. BaP is not commercially produced; it is a by-product of combustion. Its primary uses include toxicological mechanistic studies and cancer studies, as a positive control in carcinogenicity studies. There is no known commercial use for BaP.
