【摘要】：通过以Fe为归一化的富集因子、首次使用的富集因子比(R)和相关矩阵,研究了不同污染源污染的葫芦岛市3条河流沉积物中汞、铅、锌的分布特征。受氯碱污染的五里河沉积物中Hg、Pb、Zn的平均含量分别是区域沉积物背景的663、3.21、5.51倍。锌冶炼厂污染的磁山河分别是区域沉积物背景值的1 889、64.89、124倍。污染土壤污染的连山河分别是区域沉积物背景值的11.43、3.50、3.88倍。五里河沉积物中Hg的来源与Pb、Zn不同，而Pb、Zn的来源不同。磁山河沉积物中Hg、Pb、Zn来源相同。
Here,the distribution characteristics of mercury,lead,zinc in the sediment of three rivers of Huludao City,China contaminated by different pollution sources were investigated by enrichments factors using Fe as a normalizer,the ratio of enrichment factors(R) which was used firstly and correlation matrices.The Hg,Pb,Zn average contents in sediment of Wuli River which was contaminated by chlor-alkali were 663,3.21,5.51 times as high as the regional sediment background value,respectively.Those of Cishan River which was contaminated by zinc smelting plant were 1 889,64.89,124 times as high as the regional sediment background value,respectively.Those of Lianshan River which was contaminated by contaminated soil were 11.43,3.50,3.88 times as high as the regional sediment background value,respectively.The source of Hg in sediment of Wuli River is different from Pb,Zn,and the source of Hg,Pb,Zn in sediment of Cishan River is the same one.
