Benzo a pyrene. Benzoapyrene BaP is a polycyclic aromatic hydrocarbon found in coal tar with the formula C 20 H 12. The compound is one of the benzopyrenes formed by a benzene ring fused to pyrene and is the result of incomplete combustion at temperatures between 300 C 572 F and 600 C 1112 F. The main source of atmospheric BaP is residential wood burning.

It is also found in coal. Benzoapyrene BaP is a ubiquitous environmental pollutant which may contribute to the development of human cancer. The ultimate carcinogenic BaP metabolite produced by cytochrome P450 enzymes CYP such as CYP1A1 and CYP1B1 anti-BaP-78-diol-910-epoxide binds covalently to DNA and causes mutations.

The levels of various CYP isoforms can be significantly modulated under inflammatory. A benzopyrene is an organic compound with the formula C 20 H 12Structurally speaking the colorless isomers of benzopyrene are pentacyclic hydrocarbons and are fusion products of pyrene and a phenylene groupTwo isomeric species of benzopyrene are benzopyrene and the less common benzopyreneThey belong to the chemical class of polycyclic aromatic hydrocarbons.

Detectable amounts of pyrene and benzoapyrene were found on all chimney sweeps at all exposure sites. This method can thus be used to detect and quantify dermal exposure to pyrene and benzoapyrene. The results also show that pyrene and benzoapyrene may be taken up by the skin.
