ABSTRACT. A polycyclic aromatic hydrocarbon (PAH) is a hydrocarbonâa chemical compound containing only carbon and hydrogenâthat is composed of multiple aromatic rings.The group is a major subset of the aromatic hydrocarbons.The simplest of such chemicals are naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene.The terms polyaromatic hydrocarbon ⦠PAHs are usually found as a mixture containing two or more of these compounds, such as soot. PAHs generated from these sources can bind to or form small particles in the air. The results were used to evaluate lung cancer risk for the Chinese population ⦠Human health effects from environmental exposure to low levels of PAHs are unknown. 1. 2014;9:e111670. PACs can occur in complex mixtures or be synthesized as individual chemicals. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants and are the main byproducts of incomplete combustion.
