Pollution Characteristics and Source Analysis of Contaminants in Bed Sediments from Shiwuli River, Chaohu Lake

  • 摘要: 在巢湖十五里河河道上采集15个沉积物柱样,按10 cm厚度分层,得到85个沉积物样品. 通过实验室分析得到沉积物中w(TN),w(TP),w(TOC),w(Cu),w(Zn),w(Pb),w(Cd),w(Cr)以及w(Al). 在此基础上,对十五里河沉积物中营养元素和重金属污染特征及来源进行分析. 结果表明,沉积物中w(TN),w(TP)和w(TOC)存在显著相关性;w(TOC)与w(Cu),w(Zn),w(Pb),w(Cd)和w(Cr)等均具有较强的正相关关系. 由富集系数分析判定,表层沉积物中Cd和Cu为中度污染,Zn,Pb和Cr为轻度污染. 人为贡献率分析表明,Cd受人为活动影响最大. 根据多变量分析结果,结合流域主要污染源情况,初步断定化肥企业生产排污是十五里河沉积物营养元素和重金属的最主要来源,而农田水土流失和生活污水排放也是不可忽视的重要因素.
