Abstract

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 of2.8 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.
