摘　　要：于2008年3月-5月对遵义地区土壤中有机氯农药残留进行了调查。结果表明，15种有机氯农药在所有样品中都有不同程度的检出。HCHs、DDTs类物质的检出率分别为90．7％、45．7％。∑HCH残留量为未检出～12．7μg／kg，平均值为1．6μg／kg；2DDT残留量为未检出-239．7μg／kg，平均值为2．8μg／kg；总有机氯杀虫剂平均残留量为4．51μg／kg，同国内其他地区相比，其残留水平偏低。The organochlorine pesticide residues were investigated on the soils of Zunyi during the period from March to May in 2008. 15 kinds of organochlorine pesticides in soil were detected out in different levels. The detectable rates of HCHs and DDTs were 90.7% and 45.7% separately. The range of HCHs content was ND - 12.7 μg/kg with average value of 1.6 μg/kg,and the range of DDTs content was ND -239.7 μg/kg with average value of 2.8 μg/kg. The average concentration of the total organochloride pesticides was 4.51 μg/kg and the residual levels was lower than that of other Chinese region.
