摘　　要：对白洋淀水体、底泥及鲫鱼肌肉中的ＤＤＴ及其衍生物和ＢＨＣ的残留量进行了测定研究，分别给出含量范围．研究表明，鱼体肌肉中ＢＨＣ的４种异构体的含量顺序（δ＞α＞γ＞β）与其在水和底泥中的含量顺序（α＞γ＞δ＞β）略有不同．鱼体肌肉中ＤＤＴ主要以代谢物Ｐ，Ｐ′ＤＤＥ形式存在．两种农药的污染具有明显的地域差异，位于府河入淀口及村庄附近的水体、底泥及鱼体肌肉中ＤＤＴ及其衍生物，ＢＨＣ含量较高，与１９７５—１９７７年检测结果相比，鲫鱼肌肉中ＤＤＴ及其衍生物残留量下降了５４２％，ＢＨＣ下降了８６９％．DDT derivative, BHC, and their metabolites were analyzed in water, sediments and fish(Carassius auratus) muscles from six sampling stations in Baiyangdian Lake. None of the specimens monitored exceeds relevant national standards. The mean concentrations of total DDT derivatives and BHC are 0.25μg/L and 1.4μg/L in water. Total DDT derivatives and BHC range 0.56—2.26μg/kg and 0.59—2.26μg/kg (dry wt.) in sediment and range 9.2—19.4 μg/kg with mean value of 14.1μg/kg and 14.1—30.9 μg/kg with mean value of 20.9μg/kg(wet wt.) in Carassius auratus muscle, respectively. Relatively high residue levels of total DDT derivatives and BHC were detected in Dongxiangyang, Wangjiazhai and Guolikou areas of the lake. Compared with historical data, decreases of 54.2% in total DDT and 86.9% in BHC in fish muscle were demonstrated.
