| 摘 要： | 对太湖各湖区采样点沉积物的重金属Zn、Cu、Mn、Cr、Pb及营养盐Fe-P、TP含量进行分析.结果表明,太湖重金属含量高于地壳中的背景值,Cr和Pb富集程度高于其他金属.几乎所有采样点的沉积剖面的Pb含量自底部向表层迅速增加,表明1950年以来太湖流域含Pb等污染物的工业废水大量排放.竺山湾的重金属及营养盐的污染程度...

| Abstract: | The concentrations of Zn,Cu,Mn,Cr,Pb,Al,Fe,iron-bound P(Fe-P) and TP in the sediments from Taihu Lake,a eutrophic shallow lake,China,were determined.The results show that the concentrations of heavy metals are higher than those in the earth crust.Particularly,enrichments of Cr and Pb are more conspicuous than other metals.Moreover,the Pb content in all the sample sites increase markedly from bottom to top,which related to the numerous run-off of Pb-containing wastewater and atmospheric precipitation since 1... |
