Phosphorus Release from Different Sediments of Urban lakes

Sediments have a significant influence on the overlying water, and phosphorus (P) release from sediments is an important source for the lake eutrophication, particularly in shallow ones. To better understand the mechanisms of eutrophication, lakes impacted by urbanization at varying levels were investigated. The results showed TP increased continuously from the sediments of eutrophic lake, and released more with higher temperature. While phosphorous could process adsorption and desorption from sediments of mesotrophic lake. It suggested that the sediments of eutrophic lake could be the inner source of phosphorous.
