Assessment and Characterization of Heavy Metals and Nutrients in Sediments from Taihu Lake
太湖重金属和营养盐污染特征分析

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...
