Abstract

Abstract:

Using the horizontal section, the vertical section sampling and the indoor testing methods,geochemical change of HCH and DDT in soils, the representative industrial crop base on the suburbs of Xiangfan,has been analyzed.The results indicate that, in the vertical direction, the ratios of α-HCH to γ-HCH, DDE to DDD in the 20 cm place have the obvious boundary. Increasing along with the depths of soil, the sum of four isomer HCHs reduces gradually. In the horizontal direction,either the ratio of α-HCH to γ-HCH of the surface soil 〖BF〗(0-5 cm)is higher than that of the deep soil (5-20 cm) or they have the same ratios.

Key words: soil, organochlorine pesticide, geochemistry, Xiangfan
