West Lake sediment poses threat to water quality, releasing excess phosphorus.
The study looked at phosphorus in the sediment of West Lake in Fuzhou. They found that most of the phosphorus in the sediment is inorganic. This means there is a high potential for phosphorus to be released into the water. When there is less pressure from outside sources, like pollution, the sediment can release a lot of phosphorus into the water, which can affect the lake's water quality.
