城市工业区湖泊重金属污染状况——以武汉墨水湖为例

Heavy Metal Pollution in Lakes in the Industrial Park ——A Case Study of Lake Moshuihu,Wuhan

选择具有代表性的城市工业区湖泊———武汉墨水湖为研究对象,通过研究其湖水、底积物以及生物样品(鱼样)中重金属元素Hg、Cd、As、Pb、Cu、Cr、Ni、Zn的含量特征,得出结论:墨水湖湖水及生物(鱼)中重金属元素未构成污染危害;墨水湖沉积物污染严重,8种重金属元素均高出环境背景值和生态效应临界值(TEL),其中 Pb、Zn、Cr、Ni已超过生态效应必然浓度值(PEL);重金属污染是人类活动影响的结果,Ni受人类活动影响不明显。

Lake Moshuihu in Wuhan is a representative lake in the industrial park.According to the research of the contents of eight kinds of heavy metal, Hg,Cd,As,Pb, Cu, Cr,Ni and Zn, in lake water,sediment and biological samples in Lake Moshuihu,we find that the contents of lake water and biological samples have not exceeded the upper limit,but the sediment is seriously polluted. The contents of all the eight kinds of heavy metal exceed the environmental background and threshold effect level(TEL).Among them, the contents of Pb,Zn,Cr and Ni exceed probable effect level(PEL).Heavy metal pollution is the aftereffect of human activities, while Ni pollution does not show the obvious influence of them.
