摘要
在8个点位采集了抚顺地区表层土壤样品，以液相色谱法检测其多环芳烃（PAHs）含量。结果表明：土壤中PAHs单体浓度在0．6～121．0μg／kg，以3环、4环结构为主；2家化工企业附近土壤属燃煤和煤／焦炭污染源造成的轻度污染，具一定潜在致癌性。
The soil samples were collected from 8 different locations in Fushun Area and the polycyclic aromatic hydrocarbons （PAHs） contents were determined by high-performance liquid chromatography.The results showed that individual PAHs concentration ranged from 0.6 μg/kg to 121.0 μg/kg,and among them the 3-ring and 4-ring PAHs were the dominant form.The soil samples near two chemical enterprises were slightly polluted probably by coal burning, coal and coke, and the samples showed potential carcinogenicity compared with other samples.
