摘要(Abstract)：

曹妃甸和黄骅港是河北省近海工业布局和港口分布较密集的区域,对其近岸海域海水水质进行监测具有重要意义。2014年9月采集研究区近岸海域表层海水,并利用GC-MS对其中16种优先控制PAHs进行测定。结果表明,曹妃甸和黄骅港近岸海域表层海水中∑PAHs含量分别为52.6~192.1 ng·L~(-1)和85.4~156 ng·L~(-1),平均含量分别为74.59 ng·L~(-1)和121.45 ng·L~(-1)。黄骅港近岸海域∑PAHs含量高于曹妃甸近岸海域的含量,但PAHs的种类没有差异。对比其他研究区域水体中PAHs的含量,本区域表层海水中PAHs的含量处于中等水平,属于轻污染。异构体比值结合该区域现状分析初步判断,研究区表层海水中PAHs来源于石油污染和煤、生物质等的燃烧。应用风险商值法(RQ)对研究区域表层海水中PAHs的生态风险进行评价,结果表明该海域存在低生态风险,需采取措施控制PAHs的污染。
