渤海辽东湾沉积物的元素地球化学

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

几十年以来,渤海辽东湾沉积物的元素地球化学研究取得了长足的发展,尤其对辽东湾北部、南部、河口和潮间带沉积物重金属环境地球化学的研究取得了显著成果。目前,辽东湾沉积物元素地球化学的研究多集中在辽东湾北部和河口等地区表层沉积物的重金属分布和污染评价方面,对于辽东湾沉积物系统地元素地球化学,特别是稀土元素地球化学和浅地层元素地球化学研究仍有待加强。

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.
