  • 摘要: 分析了新疆孔雀河9个表层沉积物样品中22种有机氯农药(OCPs)含量,其主要OCPs含量的顺序为:六六六异狄氏剂醛滴滴涕艾氏剂硫丹Ⅱ异狄氏剂氯丹.研究表明,近期有γ-HCH输入到孔雀河,其最可能的来源是博斯腾湖的补给或孔雀河附近的农业回流水.滴滴涕的组成特征分析表明,DDTs主要源于施用的农药在好氧环境土壤中的分解,产生DDE等主要产物.风险评价表明,污染物的风险较低,所有被评估的OCPs的风险值均小于风险评价高限(ERM).
    Abstract: Nine sediment samples collected from the Peacock River in Xinjiang,were analyzed for twenty-two pesticides.The mean concentration order of the major OCPs was ∑HCH Endrin aldehyde∑DDTAldrinEndosulfanⅡEndrin∑chlordane(TC+CC).The ratio of α-HCH/γ-HCH showed new input of γ-HCH(lindane)to the Peacock River.The most possible source was the water flowing from Bosten Lake and/or the agricultural tailing water that was returned directly into the Peacock River.The compositive characteristics of DDTs indicated that the DDT compounds in sediments might be derived from DDT-treated aged and weathered agricultural soils.The degradation condition for DDT was aerobic,and the main byproduct was DDE.The risk assessment for some OCPs by effects range-low and effects range-median showed that the risk was very low.All the concentrations of evaluated OCPs were below the ERM guideline values.
