Polycyclic aromatic hydrocarbons (PAHs) are a major class of environmental pollutants mainly arising from anthropogenic activities. In this paper, the behavior and the distribution patterns of sixteen PAHs, listed as priority pollutants by the United States Environmental Protection Agency, were evaluated in 119 soil samples collected in different areas of Campania region in the southern Italy. The observation of the geochemical distribution patterns showed that both high and low molecular weight PAHs are mostly concentrated within the metropolitan area of Naples, the Agro Aversano area, and, partly, the Sarno River basin. In accordance with the Italian environmental law (D. Lgs. 152/2006), these areas should be considered potentially contaminated and not suitable for a residential use unless an environmental risk analysis does not demonstrate their safety. As a consequence, a preliminary quantitative risk assessment enhanced by the use of GIS was run revealing the existence of an incremental lifetime cancer risk higher than 1 9 10(-5) for the city of Naples and for some other populous areas.
