| 摘 要： | 利用气相色谱质谱仪(GC/MS)测定曹妃甸、山海关及沧州渤海新区表层海水样品中16种优先控制PAHs.结果表明,三个地区近岸海域表层海水中∑PAHs含量分别为14.1-226ng/L、29.9-229ng/L和97.4-254ng/L;平均含量分别为108ng/L、102ng/L和204ng/L.沧州渤海新区近岸∑PAHs含量高于曹妃甸和山海关近岸的含量,且检出的PAHs种类多.与其它国家和地区表层水体样品中PAHs含量相比较,本研究区域表层海水中PAHs含量处于中等水平.高低分子量比值和异构体比值分析表明,渤海西北部海域表层海水中PAHs主要来源于石油污染,此外,生物质及煤的燃烧也有一定贡献.应用商值法对研究区域表层海水中PAHs的生态风险进行评价,结果发现生态风险非常小.
