该文研究了杭州经济技术开发区地表水表层沉积物中有机氯农药的残留特征，采用GC-ECD法测定8种有机氯农药浓度。结果表明，沉积物中有机氯农药总量为15.77-206.05ng/g，不同采样点的污染程度存在比较大的差异；与国内外多数地区相比，下沙地表水沉积物中有机氯农药含量偏高。 DDTs和HCHs组成特征表明，近期可能仍然有新的含DDT农药成分的物质和林丹γ-HCH输入。沉积物风险评估值比较，下沙地表水沉积物的生态风险较高，可能对水体环境造成危害。

This paper studied the residues features of organochlorine pesticides in the surface sediments of Xiasha, Hangzhou.Concentrations of 8-organochlorine pesticides were determined by GC-ECD.The result showed that the concentration of OCPs in sediments was in the range of 15.77-206.05 ng/g, there was a big difference in the pollution of different sampling sites .Compared with other region , the contamination level of OCPs was a little high .Analysis of distribution characteristics of components showed that , DDTs and HCHs residues were related to input of DDTs components and Lindane γ-HCH in near term .Compared with the de-posit risk evaluation value , the surface sediments were in certain ecology risk and it was likely to cause certain harm to the environment of water .
