ELEMENTAL GEOCHEMISTRY OF SEDIMENTS IN THE LIAODONG BAY, THE BOHAI SEA

Great progress has been made in the past decades for the elemental geochemistry of sediments, especially the environmental geochemistry of heavy metals, in the northern, southern, estuarine and intertidal areas of the Liaodong Bay of the Bohai Sea. However, the study of elemental geochemistry of sediments in Liaodong Bay has been mainly focused on the distribution of heavy metals and the evaluation of contamination of the surface sediments in the northern part and estuary area of the Bay. Systematic elemental geochemistry studies,in particular,the studies of rare earth elemental geochemistry and elemental geochemistry in shallow strata need be further strengthened.
