摘　　要：于2013年对南黄海西部海域25个站位表层沉积物中多环芳烃（PAHs）进行了测定。结果表明,16种美国EPA优先控制PAHs在大部分样品中均有检出,PAHs总量水平为19.8--172μg/kg（干重）,平均含量为67.2μg/kg。沉积物中PAHs与TOC、粒度有明显的线性相关关系。与国内外其它海区相比,调查海域PAHs总体处于低污染水平。表层沉积物中PAHs主要来源于木柴、煤炭燃烧,也有部分样品显示石油源。利用沉积物质量基准法（SQGs）评价了调查海域沉积物的生态风险,调查海域沉积物中PAHs处于较低生态风险水平。PAHs content of surface sediments were tested from 25 sampling sites of the western South Yellow Sea in 2013. The results showed that 16 kinds of PAHs, which are listed as priority pollutants by EPA, were found in most samples, with total PAHs level （dry weight） 19.8-172 μg/kg and average amount 67.2 μg/kg. PAHs in sediment and TOC, particle size have obvious linear relation. Compared with other sea areas, the survey sea area was at a low PAHs pollution level. The most of PAHs in surface sediments originated from combustion of wood and coal, however, some samples showed obvious petroleum features. Based on the Sediment Quality Guidelines （SQGs）, the assessment result showed that PAHs of surface sediments from survey sea area was at a relatively low level of ecological risk.
