Based on observation data of three successive years,water pollution condition of five Yilan monitored cross sections of Songhua River was evaluated with methods of single pollution index,synthetic pollution data,shared rate of pollution load and deviation estimation of historical mean value,and a scientific evaluation conclusion has been reached.

This paper discusses the method for classifying surface water pollution and giving it a main title as well as a subtitle according to pollution share rate.

Delphi - AHP method for allocation of waste loads in a region;

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.
