Concentrations and contamination trends of heavy metals in the sediment cores of Taihu Lake, East China, and their relationship with historical eutrophication

To assess the contamination trends and potential bio-availability of sediment-bound heavy metals, concentrations of heavy metals in acid-leaching fraction and in bulk sediments from the two typical bays （the Meiliang Bay and Xuhu Bay） of the Taihu Lake, East China, were studied. Pb and Zn showed ele...
