摘　　要：通过分析测试吉林省中部农业土壤中α—HCH、β—HCH、γ-HCH、δ-HCH4种异构体和HCB的含量，对该地区HCH和HCB的残留情况进行了讨论。结果表明，在吉林省中部农业土壤中HCH4种异构体均有不同程度的检出，其中β-HCH和γ-HCH为主要的残留物。EHCH残留量介于0．42～44．96ng／g之间，平均值为5．09ng／g；EHCH残留量在不同类型土壤和不同利用方式下土壤中差异不明显。农业土壤中α-HCH／γ-HCH比值均接近于1，指示该地区土壤环境已经发生变化，也可能有新的污染源存在。土壤中HCB平均值为5．51ng／g，总体残留水平比较低，且在水田中的残留量高于在旱田中的残留量。The residual characteristics of hexachlorocyclohexane （HCH） and hexachlorobenzene （ HCB ） were discussed based on analyzing the contents of 4 isomers of HCH （α-HCH、β-HCH、γ-HCH、δ-HCH4）and HCB in agricultural soils in the central part of Jilin Province. The results showed that the four isomers of HCH were detected at different levels in its soils, of which β-HCH and γ-HCH were its major residues. The average concentration of total HCH was 5.09 ng/g with the range from 0. 42 to 44.96 ng/g in its soils. The total HCH residues had no obvious difference in the different soil types within the different soil uses. The ratio of α-HCH to γ-HCH was nearly 1, which indicated that the soil environment in this area had been changed or there might be some new pollution sources. The average concentration of total HCB was 5.51 ng/g in its soils, which the total residual concentration of HCB was lower and the residual level in the paddy fields was higher than that in the glebe fields.
