| Abstract: | The biogeochemical features of heavy metals(Fe,Mn,Cu,Zn,Ni,Co,Pb,Cd)is dis-cussed based on the survey data from the Jiulong River Estuary and Western Xiamen Har-bour during March,1987 and December,1988.The distribution of heavy metals in the areasare under the influence of the Jiulong River runoff.In the mixed process between river andseawater,the tranfer of heavy metals in suspended particles clearly occurs in correspondencewith the deposition and sedimentation of particulate phosphorus.In this mixed process Fe,Mn,Co and Zn are disadsorbed from the suspended particulate matters,as well as phospho-rus,but Cu may be enriched. There is a significant correlation between heavy metals andphosphorus in suspended particles respectively.The positive correlations between heavy met-als in suspended particles and those in phytoplankton are found in the areas.Fe and Cu areenriched on the phytoplankton with larger enriching coefficient. |
