采用气相色谱（GC －ECD ）方法分析了漳江口水产品中六六六（HCHs ）、滴滴涕（DDTs）的残留量，并对其残留水平、组成特征和人体健康风险进行了探讨与评价。结果表明：鱼类、虾类和贝类中HCHs残留量（以湿重计）分别为0.842 ng · g－1（未检出～1.42 ng·g－1）、0.374 ng·g－1（未检出～0.762 ng·g－1）、1.04 ng·g－1（未检出～1.59 ng· g－1）；DDTs残留量分别为96.3 ng·g－1（3.40～432 ng·g－1）、6.79 ng·g－1（1.53～12.1 ng·g－1）、37.0 ng·g－1（9.02～78.0 ng·g－1）。水产品中DDTs残留量鱼类＞贝类＞虾类，且其残留量均高于HCHs的残留量。与其它地区相比，漳江口水产品中HCHs、DDTs含量属于中等水平。组成特征显示研究区域近期无HCHs污染源输入，但局部区域近期有新DDT的输入，可能与三氯杀螨醇的使用有关。所采集的水产品中HCHs、DDTs残留量尚低于我国食品安全国家标准—食品中农药再残留限量（GB2763－2014），亦低于日本、欧盟等发达国家和地区相关的最大残留限量，HCHs、DDTs通过膳食的暴露暂时不会对该地区的人体健康产生危害。

The residues of Hexachlorocyclohexanes (HCHs ) and Dichloro - diphenyl - tricgloroethanes (DDTs)in aquatic products from Zhangjiang River Estuary were detected by using GC-ECD. The residues levels,compositions of HCHs and DDTs,as well as the human health risk assessment were discussed. The results showed that,the residues of HCHs in fishes,shrimps and shellfishes ranged from undetected to 1.42 ng·g-1 with an average of 0.842 ng·g-1,undetected to 0.762 ng·g-1 with an average of 0.374 ng·g-1, undetected to 1.59 ng·g-1 with an average of 1.04 ng·g-1 ,in wet weight respectively;and the residues of DDTs ranged from 3.40 ng·g-1 to 432 ng·g-1 with an average of 96.3 ng·g-1 ,1.53 ng.g-1 to 12.1 ng· g-1 with an average of 6.79 ng·g-1 ,9.02 ng·g-1 to 78.0 ng·g-1 with an average of 37.0 ng·g-1 ,in wet weight respectively. The DDTs residuals were in the order of fishes>shellfishes>shrimps,which were higher than HCHs residuals in aquatic products. Compared to other areas,the residues of HCHs and DDTs in aquatic products from Zhangjiang River Estuary were at the medium level. The composition characteristics of HCHs and DDTs showed that there was no new HCHs inputs in the survey area recently,however new DDT inputs in few area might be related to the recent usage of dicofol. The residual amounts of DDTs and HCHs in the collected aquatic products were still lower than the maximum residue limits for pesticides in food set by China (GB2763-2014),which were also lower than the maximum residue limits set by Japan,European U-nion and other developed countries and regions. Therefore,DDTs and HCHs did little harm to human health through dietary exposure in the Zhangjiang River areas.
