The Basic Theory of P-process at Sediment/Water Interface (SWI) in Lake
Abstract
Element distributions in porewater provide the considerable information about the intensities of physical, chemical, and biological processes in sediments, while sediments are the principal sink/sources for metals, sulfide, or phosphorus in lake. In many studies, the sediment/water exchange has been proved to play a dominant role in the ecological cycle of phosphorus (P), sulfide (S), or metal. The measurement method for contaminants in sediments, and the assessment of P-release risk or sediment reactivity using DGT technique have been researched for the objectives of the determination of the extent to which the sediments are either a source or a sink for contaminants or the evaluation of the effects of these contaminants on the eutrophic status of water body.
