Dibenzopyrenes are a group of high molecular weight polycyclic aromatic hydrocarbons with the molecular formula C 24 H 14.There are five isomers of dibenzopyrene which differ by the arrangement of aromatic rings: dibenzo[a,e]pyrene, dibenzo[a,h]pyrene, dibenzo[a,i]pyrene, dibenzo[a,l]pyrene, and dibenzo[e,l]pyrene.
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.

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). Pyrene forms during incomplete combustion of organic compounds. [10]
This test showed that myricetin was more effective in preventing mutagenesis initiated by certain carcinogenic polycyclic aromatic hydrocarbons (benzo(a)pyrene, dibenzo(a,h)pyrene, and dibenzo(a,i)pyrene) as compared to others in which it was less effective in preventing against mutagenesis (benzo(a)pyrene 4, 5-oxide and the bay-region diol ...
