| 摘 要： | 2008年麦收期间以网格布点法采集了聊城市137个土壤表层样品，利用ASE萃取技术，采用GC-ECD方法测定了样品中六六六（BHCs）、滴滴涕（DDTs）、六氯苯、艾氏剂、狄氏剂、异狄氏剂和七氯的检出率和残留量，并对土壤质量状况做了评价。结果表明，土壤中DDTs的检出率高达94.1％，其他6种有机氯农药（OCPs）均有不同程度检出。OCPs总残留量平均值为145.35μg／kg，其中DDTs占88.58％，是残留OCPs的主要成分。全部样点中BHCs的单因子污染指数Pi最大值为0.1，土壤未受BHCs污染；95％的样点中DDTs的Pi值小于1，土壤中DDTs含量未超标，而3％的样点Pi值小于2，土壤属轻度污染，2％的样点Pi值大于2，土壤属重度污染。

| Abstract: | 137 surface soil samples were collected in Liaocheng city using lattice method during wheat harvest season in 2008.The samples were extracted by accelerated solvent extraction(ASE)and the detectable rates and residual amounts of 7 kinds of organochlorine pesticides,including BHCs,DDTs,hexachlorobenzene,Aldrin,Dieldrin,Endrin and heptachlor,were analyzed using GC-ECD,and conducted an assessment on soil environment quality.The results showed that the detectable rate of DDTs reached for 94.1%,and other 6 kinds... |
