| Abstract: |
| The Inductively Coupled Plasma Optical Emission Spectrometer was used to analyze sediment samples collected from the Hangzhou Bay to determine major and trace elemental concentrations. Based on these concentrations, the study area can be classified into three geochemical provinces. Province I covers the northern Hangzhou Bay area and contains high concentrations of Al2O3, Fe2O3, MgO, Na2O, K2O, MnO, Cr, Cu, Ni, Pb, V, Co and Zn. Province Ⅲ is located in the western Hangzhou Bay, near the Qiantang River mouth, and contains high concentrations of SiO2, Na2O, P2O5, TiO2, Cr, Sr, Zr. Province Ⅱ is located in the middle and eastern Hangzhou Bay, with the medium concentrations of major and trace elements. The results also demonstrate that the grain size is the dominating factor controlling the spatial variations of elemental concentrations, and the Changjiang River (Yangtze River) and Qiantang River sediments play an important role in the distribution of these elements. Anthropogenic impact on heavy metal concentrations (especially Cr, Sr and Zr) can be detected in the surface sediments near the Qiantang River mouth. |
