英文摘要: Seventeen soil samples were collected from a typical pesticide contaminated site in Henan Province, China. The concentrations and distribution of hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) in the soils were investigated. The concentrations of HCHs ranged from 0.17 to 84.26 mg/kg (average 8.82 mg/kg) and that of DDTs ranged from 0.19 to 751.82 mg/kg (average 80.09 mg/kg). Vertical distribution of pollutants in soil samples indicated that the pollutants were mainly concentrated in top soils rather than deeper soils. The contribution of beta-HCH was the highest among the four HCHs isomers, and the proportion of p,p'-DDT was the highest among DDTs isomers. The spatial distributions of HCHs and DDTs in top soils were calculated by a Kriging model, revealing that soils in the historical storage and production workshop were still seriously contaminated.
