摘　　要：对华北某从事滴滴涕加工的农药厂周边的土壤和植物样品进行了取样分析,利用气相色谱/电子捕获检测器(GC/ECD)法测定了样品中的滴滴涕含量。结果表明,在生产区域下风向900m内采集的土壤样品中的滴滴涕超过《土壤环境质量标准》规定的三级标准(1.0mg/kg);植物样品中的滴滴涕均大于0.2mg/kg,超出《粮食、蔬菜等食品中六六六、滴滴涕残留量标准》的相关限值。Soil and foliage samples were taken around a pesticide plant of DDT processing in northern China. Gas chromatography-electronic capture detector （GC/ECD） was employed to determine the concentration of DDTs in these samples. DDTs in all soil samples taken from the area within 900 meters in the leeward direction were over 1.0 mg/kg, exceeding the criteria listed in ＇Environmental quality standard for soil＇ （GB 15618-1995）. DDTs in all foliage samples were over 0.2 mg/kg, exceeding the related criteria in ＇ Hygienic standards for BHC and DDT residues in grains, vegetables and other foods＇ （GB 2763- 1981 ）.
