摘　　要：采集北湖地区土壤样品分析测试土壤中持久性有机物有机氯农药,利用气相色谱仪（GC-ECD）和美国EPA8080A关于有机氯农药含量的检测方法,对滴滴涕、六六六、艾氏剂等23种有机氯农药进行定量分析.结果表明：土壤样品中有机氯农药的浓度范围为1.86~23.86 ng/g,远低于《土壤环境质量标准》（GB15618-1995）的一级标准限量值50 ng/g;说明该区域受有机氯农药六六六和滴滴涕污染程度较低,土壤中有机氯农药的污染有可能是通过大气传输过来的.This article analysed organochlorine pesticides of persistent organic pollutants By means of collecting soil samples in North Lake region.The Experiment used the gas chromatography（GC-ECD） and a detection method called EPA8080A to analyze 23 types of organochlorine pesticides.They were DDT,HCH,Aldrin,etc.The results showed the content of organochlorine pesticides in the soil ranged from 1.86-23.86ng/g which was much lower than the ＂soil environmental quality standard＂（GB15618-1995）,and it limits the quantity being worth 50 ng/g.It showed that the region affected by organochlorine pesticides DDT and HCHs were in the low-level contamination.The organochlorine pesticides contamination in soil may be transmitted from the atmosphere.
