Benzo[a]pyrene (BaP or B[a]P) is a polycyclic aromatic hydrocarbon and the result of incomplete combustion of organic matter at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F). The ubiquitous compound can be found in coal tar, tobacco smoke and many foods, especially grilled meats.
Chemical structure of benzo[a]pyrene Chemical structure of benzo[e]pyrene. A benzopyrene is an organic compound with the formula C 20 H 12.Structurally speaking, the colorless isomers of benzopyrene are pentacyclic hydrocarbons and are fusion products of pyrene and a phenylene group.
Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. The chemical formula is C 16 H 10 . This yellow-green solid is the smallest peri-fused PAH (one where the rings are fused through more than one face).
A DNA adduct (at center) of a metabolite of benzo[a]pyrene. (+)-Benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide has been shown to bind to an N2 atom of a guanine nucleobase in DNA, [2] [3] distorting the double helix structure [4] by intercalation of the pyrene moiety between base pairs through π-stacking.

One significant compound the bacteria can biodegrade is benzo(a)pyrene (BaP). [13] BaP is a polycyclic aromatic hydrocarbon (PAH), well-known organic pollutant associated with properties of teratogenicity, mutagenicity, and carcinogenicity. BaP is a degradation-resistant compound; thus, it is more inclined to accumulate in the environment. [14]
Benzo[e]pyrene is a polycyclic aromatic hydrocarbon with the chemical formula C 20 H 12. It is listed as a Group 3 carcinogen by the IARC. [1] See also. Benzopyrene;
Benz[a]anthracene or benzo[a]anthracene is a polycyclic aromatic hydrocarbon with the chemical formula C 18 H 12. [2] It is produced during incomplete combustion of organic matter. Benz[ a ]anthracene is one of carcinogenic constituents of tobacco smoke .
Dibenz[a,h]anthracene, Benzo[k]tetraphene or 1,2:5,6-Dibenzanthracene is an organic compound with the chemical formula C 22 H 14. It is a polycyclic aromatic hydrocarbon (PAH) made of five fused benzene rings. It is a fused five-ringed PAH which is common as a pollutant of smoke and oils.
