Wikipedia	License
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. The substance with the formula C20H12 is one of the benzopyrenes, formed by a benzene ring fused to pyrene. Its diol epoxide metabolites, more commonly known as BPDE, react with 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 known to be connected to soot.

Roles Classification
Biological Role(s):	Escherichia coli metabolite Any bacterial metabolite produced during a metabolic reaction in Escherichia coli. food bleaching agent A food additive that is used for the purpose of decolourising food.

Application(s):	refrigerant A substance used in a thermodynamic heat pump cycle or refrigeration cycle that undergoes a phase change from a gas to a liquid and back. Refrigerants are used in air-conditioning systems and freezers or refrigerators and are assigned a "R" number (by ASHRAE - formerly the American Society of Heating, Refrigerating and Air Conditioning Engineers), which is determined systematically according to their molecular structure. food bleaching agent A food additive that is used for the purpose of decolourising food.
