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.
Dibenz(a,h)anthracene is a polycyclic aromatic hydrocarbon with five benzene rings. It has low water solubility and low volatility and therefore occurs predominantly in solid form, white to light yellow crystalline, bound to particulates in polluted air, soil, or sediment. [2]
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.
Benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide is a metabolite of benzo[a]pyrene formed by the introduction of vicinal hydroxyl and epoxide functional groups to the fifth benzene ring. [7] These oxidations are stereoselective , producing the pair of enantiomers with the hydroxyl groups on opposite sides of the pyrene plane and with the epoxide on ...

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]
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo-p-dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [3] with the chemical formula C 12 H 4 Cl 4 O 2. Pure TCDD is a colorless solid with no distinguishable odor at room temperature.
