Benzo[a]pyrene is a polycyclic aromatic hydrocarbon (PAH) originally found in coal tar, cigarette smoke, and wood smoke. Metabolites of this compound bind DNA and induce mutations. Benzo[a]pyrene is highly carcinogenic and is used in research models to induce carcinogenesis and tumor formation.
WARNING: Strong carcinogen. Handle with care.
