摘要：
Metal contents of surface sediments were analyzed temporally and spatially in Lake Chaohu, China. No obvious temporal variations were observed, which probably due to physio- and bio- mixing, e.g. wind and microbes, in this lake. Enrichment factor of some metals were generally greater than 1.0, suggesting significant anthropogenic impact on metal levels. Significantly positive correlations between concentrations of nutrient and metals indicated that the nutrients transported to this lake contributed, to some extent, to the enrichment of metals. The correlation between trace metals concentrations indicated the co-contamination of anthropogenically derived metal enrichment in surface sediment of Lake Chaohu.
