摘  要:
2004年5月和6月采集了安徽、江苏、湖南、湖北省5个茶园的38个土壤表层样品,利用ASE萃取技术,使用GC/MS方法测定了样品中的六氯苯、氯丹、总滴滴涕(DDE、DDD和DDT)、艾氏剂、狄氏剂、异狄氏剂、七氯和灭蚁灵等八种有机氯杀虫剂。5个茶园的六氯苯、总滴滴涕的检出率都为97.4%,是茶园土壤中普遍存在的两类持久性有机污染物(POPs)。艾氏剂、狄氏剂、异狄氏剂、七氯等未检出。总有机氯杀虫剂含量平均为17.4!g kg-1,总滴滴涕占总有机氯杀虫剂含量的97.9%,是茶园土壤中有机氯杀虫剂残留的主要成分。六氯苯的残留量很低,没有对茶园土壤质量造成危害。

摘  要:
38 soil samples of Tea gardens were collected in Anhui,Jiangsu,Hunan,and Hubei provinces during May to June in 2004.The samples were extracted by accelerated solvent extraction(ASE).Using GC/MS,8 kinds of Organochloride pesticides were analyzed.Compounds were comprised Hexachlorobenzene(HCB),Chlordane,∑DDT(DDD,DDE and DDT) Aldrin,Dieldrin,Endrin,Heptachlor and Mirex.Detection ratio of HCB and ∑DDT were 97.4 percent.While,Aldrin,Dieldrin,Endrin and Heptachlor were less than the quantification limit in all samples.The total amounts of organochloride pesticides were 17.4μg kg-1.∑DDT was the primary compound in soil samples,in 97.9% of the total organochloride pesticides.The concentration of HCB was so low that made little harm to soils in all tea garden.
