摘要

研究了葫芦岛市3条具有不同污染源类型河流的沉积物中Hg，Pb，Zn的分布特征，应用相关性、富集系数以及首次引人富集系数比（R）来表征不同污染类型河流沉积物重金属间的相对污染程度及来源。结果表明：源于氯碱厂Hg污染的五里河沉积物中Hg，Ph，Zn含量平均值分别超过区域沉积物背景值662，2．21，4．51倍；受锌冶炼厂废水污染的茨山河沉积物中Hg，Ph，Zn含量平均值超过区域沉积物背景值188863．89，123．6倍；受土壤污染的连山河沉积物中Hg，Pb，Zn含量平均值超过区域沉积物背景值10．43，2．50，2．88倍。五里河沉积物中Hg来源与Pb，Zn不同；茨山河沉积物中Hg，Pb，Zn来自于同一污染源。

Abstract

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

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

and the source of Hg

Zn in sediment of Cishan River is the same one.
