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.
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.
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.

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]
Dibenz[a,j]anthracene or Benzo[m]tetraphene or 1,2:7,8-Dibenzanthracene is an organic compound with the chemical formula C 22 H 14.It belongs to the class of polycyclic aromatic hydrocarbons (PAHs) and is formed whenever there is incomplete combustion of organic matter.

Indeno(1,2,3-cd)pyrene is a polycyclic aromatic hydrocarbon (PAH), one of 16 PAHs generally measured in studies of environmental exposure and air pollution.Many compounds of this class are formed when burning coal, oil, gas, wood, household waste and tobacco, and can bind to or form small particles in the air.
