Benzo[a]pyrene

pentacyclo[10.6.2.0^{2,7}.0^{9,19}.0^{16,20}]icosa-1(18),2,4,6,8,10,12,14,16,19-decaene

C20H12 (252.0939)

Benzo[a]pyrene appears as a liquid. Presents a threat to the environment. Immediate steps should be taken to limits its spread to the environment. Easily penetrates the soil and contaminates groundwater or nearby waterways. Benzo[a]pyrene is an ortho- and peri-fused polycyclic arene consisting of five fused benzene rings. It has a role as a carcinogenic agent and a mouse metabolite. Benzo[a]pyrene is a natural product found in Angelica sinensis and Homo sapiens with data available. 3,4-Benzpyrene is a crystalline, aromatic hydrocarbon consisting of five fused benzene rings and formed during the incomplete combustion of organic matter. 3,4-Benzpyrene is primarily found in gasoline and diesel exhaust, cigarette smoke, coal tar and coal tar pitch, charcoal-broiled foods and certain other foods, amino acids, fatty acids and carbohydrate pyrolysis products, soot smoke, creosote oil, petroleum asphalt and shale oils. This substance is used only for research purposes. 3,4-Benzpyrene is reasonably anticipated to be a human carcinogen. (NCI05) Benzo[a]pyrene is one of over 100 different polycyclic aromatic hydrocarbons (PAHs). PAHs are chemicals that are formed during the incomplete burning organic substances, such as fossil fuels. They are usually found as a mixture containing two or more of these compounds. It is one ingredient of cigarette. (L10) A potent mutagen and carcinogen. It is a public health concern because of its possible effects on industrial workers, as an environmental pollutant, an as a component of tobacco smoke. See also: Tobacco Leaf (part of) ... View More ... Benzo[a]pyrene, also known as 3,4-Benzopyrene or 3,4-BP, is classified as a member of the Benzopyrenes. Benzopyrenes are organic compounds containing a benzene fused to a pyrene(benzo[def]phenanthrene) ring system. Benzo[a]pyrene is formally rated as a carcinogenic (IARC 1) potentially toxic compound. Benzo[a]pyrene is a crystalline, aromatic hydrocarbon consisting of five fused benzene rings and formed during the incomplete combustion of organic matter. Benzo[a]pyrene is primarily found in gasoline and diesel exhaust, cigarette smoke, coal tar and coal tar pitch, charcoal-broiled foods and certain other foods, amino acids, fatty acids and carbohydrate pyrolysis products, soot smoke, creosote oil, petroleum asphalt and shale oils. This substance is used only for research purposes. Benzo[a]pyrene is reasonably anticipated to be a human carcinogen (NCI05). Its diol epoxide metabolites (more commonly known as BPDE) react and bind to DNA, resulting in mutations and eventually cancer. It is listed as a Group 1 carcinogen by the IARC. In the 18th century a scrotal cancer of chimney sweepers, the chimney sweeps carcinoma, was already connected to soot. [Wikipedia] An ortho- and peri-fused polycyclic arene consisting of five fused benzene rings. Benzo[a]pyrene shows lung carcinogenicity in animal models, and it is frequently used in chemoprevention studies.
