The contents and characteristics of ten heavy metals in surface sediments from Yangzonghai Lake in Yunnan, China were analyzed. Ecological risk index presented by Håkanson to assess the potential ecological risk of Yangzonghai Lake was utilized. The results showed that the average concentrations of titanium(Ti), manganese(Mn), zinc(Zn), vanadium(V), chromium(Cr), copper(Cu), nickel(Ni), cobalt(Co),...
The objective of this study was to evaluate the spatial distribution, pollution extent and sources of heavy metal in Nansi Lake. Twenty six surface sediments were selected for determination of the total metal content. High concentrations of heavy metals including Cu, Cd, Pb, Zn, Cr, Fe and Mn, ranged from 3.15 to 230000 mg/kg-dry weight (dw). Clustering analysis was used to classify the monitoring...
