湘江（长株潭段）表层沉积物Zn污染现状分析

摘要

In this paper, surface sediment has carried on the determination of zinc and other elements in the xiangjiang river ( changzhutan section)�We analyzed the correlation between zinc and other elements, it is concluded that the xiangjiang river ( changzhutan section ) zinc content in the surface sediments from zhuzhou decreasing�Pb, Cu and Zn has the highest correlation and higher than the background value, this is mainly related to the lead and zinc smelting in zhuzhou�We need to research the migration mechanism of zinc, and escort for the xiangjiang river drinking water safety.%本文对湘江（长株潭段）表层沉积物进行了Zn等多种种元素测定，并分析了Zn与其他元素的相关性，得出湘江（长株潭段）表层沉积物中Zn含量从株洲依次递减， Pb、 Zn和Cu的相关性最高且高于本底值，这主要与株洲地区的铅锌冶炼有关，今后还需进一步研究沉积物中Zn的迁移转化机理，为湘江饮水安全保驾护航。
