摘　　要：目的探讨野生达乌尔黄鼠肌肉组织中六六六(HCHs)、滴滴涕(DDTs)、七氯、环氧七氯、狄氏剂等13种有机氯农药含量及分布特征。方法在黑龙江省哈尔滨市周边地区人工捕获野生黄鼠共50只,每只黄鼠称取2 g腿部肌肉组织,搅碎加入环己烷:乙酸乙酯(1:1)萃取,净化定容至1 mL进气相色谱检测。结果各地区所捕获黄鼠中β-六六六和p.p'-滴滴滴均未检出,HCHs和DDTs含量范围分别为1.617 8～6.030 4和10.031 5～25.896 6μg/g,七氯、环氧七氯、异狄氏剂、狄氏剂和艾氏剂的含量范围分别为4.641 3～10.319 0、0.034 6～1.203 7、0.812 2～47.480 7、0.036 2～3.358 6、0.050 3～1.725 3μg/g。结论哈尔滨市仍然存在历史残留的有机氯农药污染。Objective To explore the content and distrubution of hexachlorocyclohexane（HCH）,dichlorodiphenyltrichloroethane（DDT）,heptamul,heptachlor epoxide,dieldrin,endrin,and drinox in muscle of Citellus dauricus.Methods We captured a total of 50 wild ground Citellus dauricus in Harbin city and 2 grams thigh muscle were collected from each Citellus dauricus.Cyclohexane and ethyl acetate（1∶ 1） were used to extract the pepticides.Then the extractions were purified and fixed to 1 ml for gas chromatography detetction.Results β-HCH and p.p’-DDD were not detected in the samples.The contents of HCH,DDT,heptamul,heptachlor epoxide,dieldrin,endrin,and drinox were 1.617 8-6.030 4 μg/g,10.031 5-25.896 6 μg/g,4.641 3-10.319 0 μg/g,0.034 6-1.203 7 μg/g,0.812 2-47.480 7 μg/g,0.036 2-3.358 6 μg/g,and 0.050 3-1.725 3 μg/g,respectively.Conclusion There are still pollutions of organochlorine pepticide residues in the area of Harbin city.
