Study of Heavy Metal Speciation in Surface Sediments of Lugu Lake, China

The speciation of the heavy metals Cu, Cr, and Pb in surface sediment samples collected from Lugu Lake in China was analyzed by European Community Bureau of Reference (BCR) sequential extraction methods. Heavy metal bioavailability was assessed by risk assessment code. This study demonstrates that B...

Summary:The speciation of the heavy metals Cu, Cr, and Pb in surface sediment samples collected from Lugu Lake in China was analyzed by European Community Bureau of Reference (BCR) sequential extraction methods. Heavy metal bioavailability was assessed by risk assessment code. This study demonstrates that BCR sequential extraction methods and risk assessment code can be used as valuable tools to assess heavy metal mobility, bioavailability and eco-toxicity. The distribution of Cu, Cr, and Pb in the surface sediment of Lugu Lake showed that all three metals were mainly present in the reducible fraction. The bioavailability of the heavy metals in the surface sediment was in the order Cu > Cr > Pb.
