Benzo (a)pyrene - Wikipedia
Benzo [a]pyrene (B a P) is a polycyclic aromatic hydrocarbon found in coal tar with the formula C 20 H 12. The compound is one of the benzopyrenes, formed by a benzene ring fused to pyrene, and is the result of incomplete combustion at temperatures …
Benzo [a]pyrene | C20H12 | CID 2336 - PubChem
Benzo(a)pyrene is a biomarker of polycyclic aromatic hydrocarbon (PAH) exposure as occurs in aluminum production and coal gasification, two processes which are carcinogenic to humans (urinary bladder and lung).
BENZO[ a ]PYRENE - National Center for Biotechnology Information
Benzo [a]pyrene and other polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants formed during incomplete combustion or pyrolysis of organic material. These substances are found in air, water, soils and sediments, generally at trace levels except near their sources.
IRIS Toxicological Review of Benzo[A]Pyrene (Final Report ...
EPA has finalized the Integrated Risk Information System (IRIS) assessment of benzo[a]pyrene. This assessment addresses the potential cancer and noncancer human health effects from long-term exposure to benzo[a]pyrene.
Benzopyrene - Wikipedia
Two isomeric species of benzopyrene are benzo [a]pyrene and the less common benzo [e]pyrene. They belong to the chemical class of polycyclic aromatic hydrocarbons. Related compounds include cyclopentapyrenes, dibenzopyrenes, indenopyrenes and naphthopyrenes.
What is Benzo(a)pyrene and how is it used? Benzo(a)pyrene, or BaP, is one of a group of compounds called polycyclic aromatic hydrocarbons (PAHs). They are not produced or used commercially but are very commonly found since they are formed as a result of incomplete combustion of organic materials. Trade Names and Synonyms: BaP 3,4-Benz(a)pyrene ...
