Polycyclic Aromatic hydrocarbons ( pahs ) are persistent organic compounds. These chemicals come from both natural and man-made sources. pahs are naturally released in the environment from wildfires, volcanic eruptions, and degradation of biological materials contained in various sediments and fossil fuels (CDC/ATSDR, 1995; White and Lee, 1980). Man-made sources of pahs in the environment include the incomplete burning of organic materials ( , coal, oil, gas, wood, garbage); vehicle exhaust; asphalt; Coal-Tar and Coal-Tar based sealcoats; creosote; and cigarette and tobacco smoke (CDC/ATSDR, 1995; CDC, 2009; EPA, 2009; National Research Council, 2009).Many pahs are of concern because of their harmful impacts on humans and the environment.
