摘要: The Bohai Sea (BS) and Yellow (YS), which are adjacent to the most urbanized industrialized areas in China, facing a variety of environmental problems. Two cruises were conducted investigate pollution status toxic metals BS YS sediments. They generally presented decreasing trend from near shore offshore. In addition, two high concentration observed central south north Shandong Peninsula. results multiple regression analyses suggest that Hg is mainly controlled by anthropogenic loading, whereas for Cr, Cu, Ni, Pb Zn, sediment properties, especially Fe oxides content, play more important role. For As Cd, contribution loading properties comparable. risk assessment indicates Hg, As, Cd Ni should be listed as primary contaminant YS.
