摘　　要：用气相色谱法对吉林省中部土壤样品中有机氯农药的分析结果表明,吉林省中部土壤中有机氯农药以六六六(HCH)和滴滴涕(DDT)为主,艾氏剂、氯丹、狄氏剂、异狄氏剂和七氯等也有不同程度的检出。总DDT含量为0.02～69.35μg/kg,平均含量为3.01μg/kg;总HCH含量为0.47～13.47μg/kg,平均含量为2.00μg/kg。p,p′-DDE和p,p′-DDD为DDT的主要存在形式,主要为过去输入的DDT的降解产物,但近期仍有少量DDT的输入;HCH的4种异构体中以β-HCH为主,α-HCH与γ-HCH的比值较低,表明HCH在土壤中残留的时间很长。Organochlorinated pesticides in soils of the middle Jilin province were analyzed with gas chromatography, to understand the present content and composition. Hexachlorocyclohexane （HCH） and dlchlorodlphenyltrichloroethane（DDT） were the main kinds of organochlorinated pesticides in the area and aldrin, chlordane, dieldrin, endrin and heptachlor were also detectable to some extent. The total contents of DDT were between 0.02μg/kg and 69.35μg/kg, with the average of 3.01μg/kg. The total contents of HCH were between 0.47μg/kg and 13.47μg/kg, with the average of 2.00μg/kg. p,p＇-DDE and p,p＇-DDD were the main existing form of DDT and they were mainly the degradation product of DDT input in the past, but a little DDT was input recently. β-HCH was the major isomer of riCH and the lower ratios of α-HCH and γ-HCH indicated that HCH has stayed for long time in soils in this area.
