摘要：Distribution and speciation of heavy metals (Cd, Cr, Cu, Zn, Pb and Ni) in sediments collected from Donghu Lake were investigated in this work. Compared with background concentrations in the soils of surrounding the lake, Cd had the highest levels of contamination, followed by Zn. The concentrations of the remaining heavy metals (Cr, Cu, Pb, and Ni) were comparable with these background values. In all three sampling sites, Cd, Cu, and Zn had the highest bioavailability and, therefore, posed a higher ecological risk than the other metals studied. Cr, Zn and Pb clearly show significant correlations in the sediments (p
