采用气相色谱-质谱联用技术测定了罗马尼亚东南部17个地区表层土壤中的16种优先多环芳烃（PAHs），其中包括加拉蒂钢铁厂和加拉蒂县Lower Prut Meadow自然保护区附近的地点。研究土壤中多环芳烃（TPAHs）总浓度为0.003 mg/kg ~ 38.524 mg/kg干重。根据罗马尼亚关于不同用途土壤中微量有机化合物的立法，工业区土壤中多环芳烃的含量超过了大多数个别多环芳烃的正常值。在普鲁特河流域的一个动物技术农场附近采样的土壤中，TPAHs和苯并[b]荧光蒽的警戒水平超过了较不敏感地区，而在甲苯、苯并[a]蒽、苯并[k]荧光蒽和苯并[g，h，i]苝的警戒水平超过了敏感地区。PAR污染土壤的来源复杂，既有热成因，也有岩成因。(C) 2011 Elsevier B.V.版权所有
Gas chromatography-mass spectrometry was used for the determination of 16 priority polycyclic aromatic hydrocarbons (PAHs) in surface soils from seventeen areas in Southeast Romania, including sites placed in the vicinity of Galati iron and steel plant and Lower Prut Meadow natural reserve in Galati County. The total concentration of PAHs (TPAHs) in the investigated soils ranges from 0.003 mg/kg to 38.524 mg/kg dry weight. According to Romanian legislation for trace organic compounds in soils of different uses, the amounts of PAHs in soils from the industrial zone exceed the normal values for the majority of individual PAHs. The lowest concentrations were found in soils sampled from the protected area of Lower Prut Meadow natural reserve and the highest near a zootechnique farm in the Prut River basin, where the alert levels exceeded for the less sensitive area in the case of TPAHs and benzo[b]fluoranthene and for the sensitive area in the case of chrysene, benz[a]anthracene, benzo[k]fluoranthene and benzo[g,h,i]perylene. The sources of PAR contaminating soils are complex, being of both pyrogenic and petrogenic origins. (C) 2011 Elsevier B.V. All rights reserved.
