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-C10 through n-C36) 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.
本文研究了意大利北部、中部和南部三个油罐区污染土壤中烃类污染源的识别。检测了母体多环芳烃（萘到苯并（g，h，i）苝）和正构烷烃（正十烷到正三十六烷）。通过其分布模式、特征比值以及较少使用的标志物的确定，对源分配进行了研究。研究数据表明，正构烷烃来源于人为和生物源，而多环芳烃则来源于石油源和热解源。确定了多种在初步环境评估中未考虑的烃类污染源。多标准方法的应用可以定位影响研究地点的石油污染来源。结果表明，应用多标准方法进行源识别是评估环境损害的关键，证明必须进行准确的源识别研究。所提出的方法是管理污染场地和规划适当清理干预措施的有用工具。
