Effect of nutrient concentration of overlying water on nitrogen and phosphor release from sediment in Lake Baiyangdian was studied in this paper. The results indicated that nutrient levels of overlying water impacted the release rate significantly. The average release rates were negatively correlated to the nutrient levels of overlying water. The release curves of absolute amount for total nitrogen...
Chemical sequential extraction was employed to analyze the phosphorus species in surface sediments in the representive five sites of Lake Baiyangdian. The results showed that exchangeable phosphorus(Ex-P) was the lowest fraction and had little effect to eutrophication of Lake Baiyangdian. The ironbound phosphorus(Fe-P) was the main fraction. The release of Fe-P in sediment was an important process...
The pollutants, which were brought by the living and producing of the village in Lake Baiyangdian, would have some effects on surrounding water quality. During May 2009 to March 2010, the research evaluated and analyzed the eutrophication state of five selected sampling points. Experimental result indicated that, the water around the village appeared eutrophication phenomenon overall, fish and poultry...
