Abstract:The distribution of heavy metal (Cr, Cu, Cd, Pb, Zn and Ni) speciations in surface sediments from the typical ecologically sensitive regions of Yantai coastal zone were analyzed by the Tessier sequential extration method. The results showed that the concentrations of heavy metals (Cr, Cu, Zn and Ni), especially Cd, were quite high in the estuary region and sewage outlet region. The concentrations of heavy metals in the mariculture region were basically consistent with the first class standard of Marine Sediment Quality of China. The heavy metals of Cr, Cu, Pb, Zn and Ni in research regions were mainly existing in residual fraction. However, the extractable phase proportion of Cd in the estuary region and sewage outlet region were up to 90% and the bioavailability of Cd was highest among these heavy metals.
Keywords:Yantai coastal zone  ecologically sensitive regions  surface sediment  heavy metal  speciation
