摘　　要：采用气相色谱-质谱法定量测定桑沟湾海域水体中有机磷农药残留,分析了其组成与分布特征。2009年4月(春季)和10月(秋季)桑沟湾海域水体中8种有机磷农药的含量测定结果表明:桑沟湾有机磷农药的总浓度水平是春季小于秋季,有机磷农药的总浓度范围为0.001～0.265μg/L,均值为0.061μg/L。该海域水体中共检出6种有机磷农药,马拉硫磷和对硫磷是桑沟湾水体中主要的有机磷农药污染物。有机磷农药分布特征大致呈现春季表层水体中近岸高,离岸低,由湾口向湾内递减,底层水体中在湾口处浓度最高;秋季表层水体中由西北岸、东北湾口向湾中央渐增,底层水体中呈现由湾内向湾口递增的趋势。本研究提供的数据可为了解该海域的有机磷农药污染分布情况提供参考。Organophosphorus pesticides （OPPs） of composition and distribution characteristics in the sea waters of Sanggou Bay have been studied by Gas Chromatography-Mass Spectrometry （GC-MS）. Eight OPPs in the seawaters of Sanggou Bay were determined by using GC-MS with the external standard quantitative method in the Spring and Autumn of 2009. The range of concentration of ∑OPPs in the bay was 0. 001 - 0. 265 μg/L with an average of 0. 061 μg/L. Six different types of OPPs were detected with the main pollutants being malathion and parathion. The distribution of OPPs from the survey in Sanggo concentration of OPPs is higher in the centre, lower u Bay are presented in this paper. The results show that the far from the shore and decreasing from the outside to the inside of the bay at the surface water body, with the highest concentration at the bottom water body near the mouth of the bay in Spring. The concentration of OPPs increases from northwest and northeast outside of the bay to inside at the surface water body and increases from inside to outside at the bottom water body in Autumn. The results provide some references for the distribution characteristics of OPPs in this region.
