    Abstract:

    Investigations on residues of organochlorine pesticides (OCPs) in soils in Huizhou, China were conducted. A total of 42 soil samples were collected from sites representative of the region for analysis of contents of OCPs. And with the aid of multi-variate geostatistics and GIS, residue and spatial distribution of 17 types of OCPs were analyzed. Results show that the 17 OCPs were detected, various in content in all the soil samples. HCHs and DDTs residues were detected, but below the criteria of the national standards for soil environment quality. Residue content of β-HCH was the highest among HCHs, which implied some recent input of HCH to soils, while for DDT, no sign of new input was found. Compared with other regions in the country, Huizhou city was lower in soil HCH and DDT content. Principal component analysis demonstrated that the abovesaid 17 OCPs in the soil may have 5 major contributors, corresponding respectively to industrial use of HCH, natural factors, use of lindane, use of heptamul and use of Drinox. By means of ordinary Kriging interpolation, spatial distribution of OCPs was studied with results indicating that the 17 OCPs variaed greatly in spatial distribution between types.
