Open publisher page 2 citations

Abstract

The quantity of phosphorus that can release to water in sediment of East Lake, Wuhan is 439.4t with the excessive loading of phosphorus as assessment index. Determination about the release of phosphorus in sediment showed that the rate of P release is 9.47mg/m2·d. The proportion of phosphorus in water sourcing sediment reaches to 25%. Internal loading of phosphorus would maintain higher level of P in water in 20 years without any external loading.
