Abstract
The probable mechanism of dredging on effectively controlling sediment internal P release to overlying waters is primarily to the removal of surface sediments rich in TP and/or OM combined with inactivation of P to iron (Fe) (hydr)oxides in the upper 20 mm active layer sediments. Variations of SRP and soluble Fe (II) (a, c) measured by HP-Peepers and labile P and Fe (b, d) measured by DGT with depths in non-dredged and post-dredged sediments at the end of experiment. The location of the sediment-water interface is represented by zero. Values are means ± SD of three replicates. Variations of adsorption isotherm parameters with sediment depths using the nonlinear form of the Langmuir equation in non-dredged and post-dredged sediment profiles at the end of experiment.201
