Abstract

BCR three stage sequential extraction procedure was applied to examine the spatial occurrence characteristics and relative ratio of the speciation of Cr, Ni, Cu, Zn, As, Cd, Hg and Pb in the sediments from Danjiangkou reservoir, and meanwhile their stability and pollution assessment were discussed. All types of metals had obvious spatial heterogeneity; their high value was grouped in the middle of the reservoir, the west of tributaries and the northwest of Danjiang reservoir. Most metals mainly existed in residue state except for Pb and Cd, the reducible Pb and acid soluble Cd respectively accounted for 54.91% and 42.19% of the total content. The stability of eight studied metals was in the order of Cr >Pb >As >Ni >Cu >Hg >Zn >Cd. Cd was unstable in most studied sites, and there was higher risk of quick desorption and release.

Key words： Danjiangkou Reservoir sediment heavy metal speciation stability sequential extraction
