WebPolycyclic aromatic hydrocarbons are a group of chemicals that occur naturally in coal, crude oil, and gasoline. PAHs are also present in products made from fossil fuels, such as coal-tar pitch, creosote, and asphalt. When coal is converted to natural gas, PAHs can be released.

Polycyclic Aromatic Hydrocarbons (PAHs) Factsheet
WebAbstract. Polycyclic aromatic hydrocarbons (PAH) comprise the largest class of cancer-causing chemicals and are ranked ninth among chemical compounds threatening to humans. Although interest in PAH has been mainly due to their carcinogenic property, many of these compounds are genotoxic, mutagenic, teratogenic, and carcinogenic. WebPolycyclic aromatic hydrocarbons (PAHs) are a large group of diverse organic compounds that contain two or more fused aromatic rings ranging from the two-ring naphthalene … WebPAHs generally have a low degree of acute toxicity to humans. Some studies have shown noncarcinogenic effects that are based on PAH exposure dose [Gupta et al. 1991]. After chronic exposure, the non-carcinogenic effects of PAHs involve primarily the. pulmonary, gastrointestinal, renal, and dermatologic systems. undiluted whiskey
