摘  要:
为了系统研究和探讨长江中下游地区湖泊重金属污染状态和趋势,分析比较了巢湖、洞庭湖、墨水湖、太湖和鄱阳湖等湖泊沉积物重金属污染,并讨论了重金属的具体来源,提出了相应的防治对策。结果表明,污染状况最为严重的是墨水湖,Cr、Pb、Cu和Zn都超标,而东洞庭湖沉积物中的Cd含量高出其他湖泊很多。治理情况最良好的属太湖,2001~2011年Pb、Zn和Cu含量均大幅降低。

摘  要:
In order to study pollution status and trend of heavy metals in lakes of the middle and lower reaches of Yangtze River,the status of heavy metals in sediments of Chaohu,Dongtinghu,Moshuihu,Taihu and Poyanghu were analyzed and compared,the specific sources of heavy metals were discussed,and corresponding countermeasures were put forward.The results showed that Moshuihu was the most seriously polluted lake among the above lakes.The contents of Cr,Pb,Cu and Zn all exceed.The content of Cd in Dongtinghu was higher than that in other lakes.A good governance appeared in Taihu with significantly reduction of Pb,Zn and Cu from 2001 to 2011.
