| Outline of Final Research Achievements |
In the current study, we quantified P compounds classes in sediment and suspended particles in a shallow eutrophic Lake Kasumigaura, Japan. We found that biogenic P classes are predominant in suspended particles and they change the particulate P (PP) concentrations. In sediment, organic P in the solid phase is the most important source for P in pore water, at least from December to April. From inflow river to the lake, we found that inorganic P is dominant in the inflow river whereas organic P is dominant in the inside of Lake Kasumigaura.
