摘  要：
为了解有机氯农药企业搬迁遗留场地土壤的污染状况,采用气相色谱法定量分析了北京市原某农药厂表层土壤中的有机氯农药(六六六和滴滴涕)。结果表明,土壤中HCHs的浓度在1mg·kg-1到440mg·kg-1之间,DDTs的浓度在5mg·kg-1到966mg·kg-1之间。通过对污染物组成的分析发现,HCH异构体中β-HCH,DDT异构体和代谢产物中DDD含量相对较高。结果说明,从1981年此农药厂停止生产农药产品至今,经过20多年的降解,厂区土壤污染依然非常严重。通过克立格插值方法绘出的等值线图可以看出,厂区中部农药生产车间和南部农药存放场地土壤污染最为严重,污染物浓度要高于土壤需要进行修复的调解值。

摘  要：
Organochlorine pesticides(HCH and DDT) in the topsoils of a former pesticide site in Beijing were quantitatively analyzed in order to understand the soil pollution situation of the former organochlorine pesticide manufacturing enterprise.The results showed that the concentrations of HCHs in the soils were in the range from 1 mg·kg-1 to 440 mg·kg-1,the contents of DDTs in the site ranging from 5 mg·kg-1 to 966 mg·kg-1.The contents of β-HCH among HCH isomers and of DDD among DDT isomers and metabolites were relatively higher through the analysis of the pollutants compositions.The results demonstrated that the soil pollution in the site was still very severe although the production of these pesticides had been prohibited for more than 20 years since 1981.The most serious soil pollution occurred in the manufacturing area located in the middle of the site and the storage sites in the south area through the contour lines drawn by Kriging interpolation method.The contents of the pollutants were higher than the intervention values of the soil remediation.
