| 摘 要： | 调查了大沽排污河沉积物中持久性有机氯农药(OCPs)的残留状况。在所选取的7个断面的沉积物样品中均有大量六氯环己烷(BHC)及其衍生物和双对氯苯基三氯乙烷(DDT)及其衍生物检出。数据表明,OCPs残留物可能主要来自农田土壤的残留,近期基本无新的污染源输入。与国内外部分河流表层沉积物中BHC和DDT的含量相比,大沽排污河沉积物中有机氯农药含量较高。

| Abstract: | The residual amounts of organochlorine pesticides(OCPs) in the sediments of Dugu Drainage River were studied.A total of 7 surficial sediment sites were selected along the river.The frequency of detection of BHC and DDT in all sediment samples were up to 100%,which illustrated that the contamination of BHC and DDT was serious in Dugu Drainage River.Results indicated that the residue of organochlorine pesticides may mainly comes from the farmland,and there are not new pollution sources recently.For the contents of OCPs in surficial sediments of some rivers,the values in Dugu Drainage River were higher. |
