Freshwater lakes are severely threatened, due largely to excess inputs of nutrients and other contaminants. Phosphorus (P) is receiving renewed attention due to recent increases in toxic cyanobacteria blooms in lakes worldwide. We investigated groundwater seepage for its role in P loading dynamics ...
The surface waters of Rathbun Lake watershed in southern Iowa are impacted by agricultural sources of sediments and nutrients, including phosphorus (P). Because stream sediments often play an important role in regulating P concentrations in stream water, we investigated sediment-water column P relation...
The accumulation of rainfall had the greatest impact on surface runoff TP loss, with the correlation coefficient reaching 0.994 (P < 0.01), while surface runoff particulate phosphorus loss was mostly affected by the average rainfall intensity. (3) Modifying the forest structure in water source ...
Soil Test Phosphorus and Clay Content Effects on Runoff Water Quality Dissolved phosphorus (P) in runoff increases with an increase in soil test P, but slopes found for this relationship vary by an order of magnitude. A diffe... FR Cox,SE Hendricks - 《Journal of Environmental Quality》 被...

We assessed the prevalence and causes of sediment phosphorus (P) release within urban stormwater ponds, a process that may reduce P removal by sedimentation. Data collected from surface water of 98 urban stormwater ponds in Minnesota showed that nearly 40% had median summer total P concentrations ...
Prediction on pollution contribution of N and P from agricultural non-point source pollution in Poyang Lake watershed Non-point source pollution from agriculture is a major cause of water quality problems, above all, nutrients such as Nitrogen (N) and Phosphorus (P) from v... P Li,B Zheng,...
