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 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).

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.

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.

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.

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 ...

Benzo[a]pyrene (B[a]P) is the main representative of polycyclic aromatic hydrocarbons (PAHs), and has been repeatedly found in the air, surface water, soil, and sediments. It is present in cigarette smoke as well as in food products, especially when smoked and grilled.

2012年2月1日 · Benzo[a]pyrene, a representative polycyclic aromatic hydrocarbon, is one of the human genotoxic carcinogens (IARC Group 1) showing tumorigenic potential in virtually all in vivo experimental animal model systems.

Fumes that develop from fat dripping on hot charcoal are rich in benzopyrene, which can condense on grilled foods. • It has been estimated that more than 20% of the carbon in the universe may be associated with PAHs.

Benzo[a]pyrene, an aromatic hydrocarbon produced in small amounts by the combustion of organic substances, contains five fused benzene rings. Like several other polycyclic aromatic hydrocarbons, it is carcinogenic.
