| Abstract: | To examine the impact of Corbicula fluminea on sediment properties and phosphorus dynamics across sediment-water interface in lake,the microcosm experiment was carried out with sediment and lake water from the estuary of Dapu River,a eutrophic area in Taihu Lake.Rhizon samplers were used to acquire pore water,and soluble reactive phosphorus(SRP) flux across sediment-water interface and sediment properties were determined.The activity of C.fluminea destroyed the initial sediment structure,mixed sediment in d... |
| Keywords: | bioturbation soluble reactive phosphorus phosphorus fraction ferrous iron Taihu Lake |
