The present paper deals with identification of hydrocarbon sources in contaminated soil of three tank farms located in north, central and south Italy. Parent polycyclic aromatic hydrocarbons (naphthalene through benzo(g,h,i) perylene) and n-alkanes (n-C-10 through n-C-36) were determined. The study of source assignments was carried out by their distribution patterns, their diagnostic ratios, and determination of less-commonly used markers. The data show anthropogenic and biogenic origin of n-alkanes and petrogenic and pyrolytic sources of PAHs. Multiple sources of hydrocarbons, that were not considered in the preliminary environmental assessments, are identified. The application of a multi-criteria approach allows to locate petroleum pollution sources that affect the study sites. The results demonstrate that the application of a multi-criteria approach for source identification is a key point to assess environmental damage and prove that an accurate study of source identification has to be performed. The suggested methodology is a useful tool to manage contaminated sites and to plan appropriate interventions of clean up. (C) 2013 Elsevier B.V. All rights reserved.
