Based on the experiment of the phosphorus forms and the effect factors of phosphorus release from sediment in the urban shallow lake (taking Lake Xuanwu as a example), the results showed that when the water body had higher pH value during the excess alga period, phosphorus in the sediment was released deeply and the total dissolved phosphorus (TDP) was increased from 0.049 mg/L to 3.255 mg/L as 66...
After water storage of Laohutan reservoir, nitrogen (TN), total phosphorus (TP) and ammonia nitrogen (NH3-N) are the main pollutants. In the first month of water collection, the vertical distribution of TN, TP and NH3-N concentrations is increased distinctly from the surface layer to the bottom layer. It shows that the reservoir water quality is affected by pollutants released from submersed soil...
