    ABSTRACT: Soil samples in contaminated site of a historical HCH plant were collected and the levels and the distribution of HCH were analyzed and studied. The highest level of SigmaHCH was 271.72 mg kg(-1). The contamination of HCH was mainly in 0 - 40 cm depth of soil, while the concentration of HCH in 0 - 40 cm depth of soil was much more than that in 40 - 150 cm depth of soil. The concentration of beta-HCH was much more than other three kinds of isomers. The distribution of HCH in 0 - 20 cm depth of soil was calculated by Kriging model. The induration of the surface soil, which stopped the rainwater infiltrating, made theconcentration of HCH reduce with depth and made the depth of contaminated soil shallow.
