Abstract

Abstract

Metal co mplexing ligands concent rations of the Huanghe Estuary,Qingdao coastal,Daya Bay and South Sea China waters were determined by the anodic stripping voltammetry(ASV)technique.The distribution regularity and the relationship with other parameters were discussed.The results ae as follows:Metal ligands concentrations of the South China sea waters are a little higher than those of other waters,and they are apparently higher than those of the ocean.Metal complexing ligands concentration shows the enrichment phenomenon in the sea surface microlayer.The metal complexing ligands concent ration profiles of the South China Sea show that the value of sea surface is the highest,then decreases with the depth accrueing,and a higher value appears at the bottom.Ligands concentrations of copper are higher than those of cadmium and lead.The property of ligands in each waters exhibits complicated.In short,the distribution regularity of metal complexing ligands concentration in China coastal waters is consistent with that of other regions in the world.Meanwhile,the positive relationship between copper ligands concent ration and BOD,COD,DOC and the viscosity are found obviously.
