Benzo[e]pyrene, also known as B(e)P, is a highly toxic member of a family of compounds called polyaromatic hydrocarbons (PAHs). It is a pentacyclic aromatic hydrocarbon contaminant and a structural isomer of the potent carcinogen benzo[a]pyrene. Found in the environment, particularly in industrially active areas, it is a significant component of air pollution. Benzo[e]pyrene is present in tobacco smoke. Metabolized in the body, it generates reactive metabolites that interact with DNA and other cellular components, causing mutations and cellular changes. Additionally, Benzo[e]pyrene is believed to induce oxidative stress and inflammation, further damaging cellular components.
