Based on GIS,nitrogen and phosphorus load were calculated and displayed as spatial maps.

The effects of periodic starvation on nitrogen and phosphorus budgets of Litopenaeus vannamei and environmental N&P loading were discussed in this paper.

② Spatial variations of N and P pollution were observed, as the creeks in different places accepted different types and amounts of pollutants.

Contribution of pollution load of storm runoff in urban areas of Hanyang, Wuhan City on the receiving water;

Sorption-desorption behaviors of Cd~(2+) and Pb~(2+) in different pollution load soils;

Water pollution load in coastal zone of Xiamen:Estimation and forecast;

On the basis of the social, economical and investigated environmental monitoring data, the results revealed that the pollutant load of Yangtze River in Jiangsu province contains 210 997.

Current and future water quality condition of Dapeng Bay was simulated using Delft 3D model on the base of pollutant sources investigation and pollutant load estimation.

The relationship among rainfall,the soil N content in the watershed and N pollutant load at the exit of the watershed was analyzed by mathematic model in the paper,using the soil N moving law in order to reveal the mechanism how N pollution works.

Sources and quantities of main water pollution loads released into Three-Gorge Reservoir of the Yangtze River;

The researches on decreasing the pollution loads in rainfall runoff with PAM and functional materials of zeolite to improve the soil was accomplished using the simulated set.

The paper studied the characteristics and pollution loads of the enzymatic and chemical deinking effluent,the cumulative pollutant of deinking effluent which is recycled several times.
