| Abstract: | BCR three stage sequential extraction procedure and ICP-AES were applied to examine the speciation and concentration of heavy metals in sediment of Taihu lake to determine the bioavailability of these heavy metals.Results show that Mn had relatively higher bioavailability than other heavy metals of Taihu lake.The northern part of Taihu lake had the highest ecosystem risk compare to the other parts.The relationship between TOC and speciations of heavy metals in the sediments was also explored. |
