摘要
以辽东湾表层海水中多环芳烃为研究对象,利用气相色谱-质谱联用仪对2014年5月和8月16个站位表层海水中优先控制16种多环芳烃进行分析,并对多环芳烃的分布特征、组成、污染水平和主要来源等方面进行了探讨。结果表明,5月和8月辽东湾表层海水16种多环芳烃平均含量分别为367.4ng/L和138.2ng/L,季节变化明显;海水中多环芳烃主要以低环为主,高值区主要分布在辽东湾西南部海域,以及金州湾和普兰店湾附近海域,高值区的分布可能受到了石油平台和石化园区等因素影响;5月海水中多环芳烃主要来源于石油源和燃烧源的混合来源,8月主要来源于石油源。
Sixteen samples were analyzed in surface seawater at sixteen stations from Liaodong Bay using Gas Chromatography-Mass Spectrometer（GC-MS）in May and August of 2014 and the distribution,composition,pollution level and main sources of PAHs were discussed.There was average PAHs concentrations of 367.4ng/L in May and 138.2ng/L in August,with significant seasonal change in PAHs in surface seawater.Low-molecular weight PAHs had larger percentage than high-molecular weight PAHs.The high concentration areas of PAHs were usually in the southwest of Liaodong Bay,the sea area of Jinzhou Bay and Pulandian Bay.The distribution patterns were affected by the oil platforms and petrochemical industry garden.The PAHs was derived primarily from the mixed sources of petroleum source and combustion source in May,and petroleum sources were the main sources of PAHs in August.
