Trace metals distribution in huanghe (Yellow River) estuarine sediments

Huanghe River and estuarine sediments were analyzed to determine Fe, Mn, Pb, Cu, Zn, Cr, Ni, Al, etc. The results show that the concentrations of these elements are relatively lower than in most of large world rivers/estuaries. The heavy metal distribution in Huanghe River estuary is mainly controlled by the natural sedimentary dynamics processes and most likely poorly affected by anthropogenic contamination. Despite an important sedimentation occurring near the river mouth, a large amount of suspended matter is transported north-eastwards and along the coast line in winter. A significant resuspension of surface sediments occurs during storm periods and plays an important role in the particulate heavy metal distribution in the Huanghe River estuary.
