Abstract

Abstract

The variation of colloidal phosphorus with salinity in esturary was studied,which was compared with that of particle and truly dissolved phosphorus with the purpose of finding out the similarities and differences between behaviors of them. Distribution patterns of phosphorus in particle,colloidal and truly dissolved phase under different salinities and their relationships with suspended particulate matter were also researched to understand the transformation and transportation of colloidal phosphorus in estuarine area. The result shows that the concentrations of total colloidal phosphorus,organic colloidal phosphorus and inorganic colloidall phosphate all descend from river-end to sea-end,illust rating their terrigenous source1 Ratios of organic to total colloidal phosphorus decreased with salinity,indicating that organic phosphor us was influenced by scavenge process of colloid more significantly compare with inorganic phosphate. Both of the phosphorus variation tendencies and the proportion between organic and inorganic phosphorus in colloidal phase were similar with that in truly dissolved phase while different from that in particle phase.
- truly dissolved phase,
- colloidal phosphorus,
