Benzo[a]pyrene

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) that consists of five fused benzene rings. It has the chemical formula C20H12 and a molecular weight of 252.32 g/mol.

BaP is formed during the incomplete combustion of organic matter and is found in coal tar, crude oil, and cigarette smoke. It is also used as a starting material in the synthesis of other organic compounds, such as dyes, pigments, and pharmaceuticals.

BaP is considered to be a potent human carcinogen by various regulatory agencies due to its mutagenic and genotoxic properties. Exposure to BaP has been linked to an increased risk of cancer, particularly lung and skin cancers. BaP is one of the most extensively studied PAHs and has been found to cause cancer in laboratory animals. Therefore, appropriate safety precautions should be taken when handling BaP to minimize the potential risks to human health and the environment.
