摘要
用气相色谱方法对新疆奎屯河流域五个采样点的土壤样品中残留的HCH进行分析,结果表明:天北新区葡萄园HCH残留量最高,HCH s达2 415.46μg/kg,远远超过了无公害农产品粮食类产地土壤质量指标(≤500μg/kg)。其次是古尔图镇北11 km棉地,125团西侧2 km弃耕地,古尔图镇北6 km棉地,苏来曼克斯套林场。HCH在土壤剖面中的纵向分布总体上是随着土壤剖面的加深而降低。HCH各异构体中以γ-HCH残留最大,可能是使用林丹粉(主要成分是-γHCH)的缘故。
The distribution of HCH in soil samples of Kuitun River Basin in Xinjiang area was studied by the gas chromatography （GC ）. The result shows that the highest concentration of HCH can be found in the New District Grapery of Tianbei. The amount of HCHs reaches 2 415.46 μg/kg this area, which has far exceeded the index （≤500 μg/kg） of the soil quality of nuisanceless agricultural products. Concentration in the cotton field located in the 11km north of Guertu Town is the next. Then the concentrations from the highness to the low lever are the derelict land in the west of the 125th Regiment, the cotton field located in the 6km north of Guertu town and the Sulaimankesitao Forest Farm. The concentration of HCH decreased with the depth as a whole. The concentration of γ-HCH is the highest among the HCH isomers. Using Lindane powder（γ-HCH is the chief component） maybe the main reason.
