Assessment of Cu, Pb and Hg Contamination in Bottom Sediments Of Surface Water in XuZhou

Abstract： Pollution of heavy metals Cu,Pb and Hg is assessed using geo-accumulation index in this paper. The result shows that the bottom sediments of surface water in Xuzhou is polluted by these heavy metals to deferent degrees, of which the Jinma River is the most serious, and then the Kuihe River, the abandoned Yellow River, and the Jinghang Canal. The Yunlong Lake has also been polluted by Hg. The three kinds of heavy metals in the order of concentration is Hg＞Cu＞Pb. The pollution degree and the type of element is closely related with industrial structure in Xuzhou. 作 者： 王曉    韓寶平    朱雪強(qiáng)   作者單位： School of Environment and Spatial Informatics, CUMT, Xuzhou, Jiangsu 221008,China  期 刊： 中國(guó)礦業(yè)大學(xué)學(xué)報(bào)(英文版)  ISTICEI   Journal： JOURNAL OF CHINA UNIVERSITY OF MINING AND TECHNOLOGY  年，卷(期)： 2004, 14(1)  分類(lèi)號(hào)： X13  Keywords： srface water    bottom sediment    heavy metal contamination    index of Geo-accumulation
