Research Status on the Influences of Pollutant Adsorption on Characteristics of Sediment Movement

The interaction of pollutants and sediment is very complex.On the one hand,sediment influences the behaviors of adsorption and desorption of pollutants,on the other hand,the surface morphology of sediment changes after adsorbing pollutants,and the mechanical movement characteristics of sediment change,so people pay more and more attention to the influences of pollutant adsorption on the characteristics of sediment movement.In the article,we summarized the research situations at home and abroad,such as the influences of surface features of polluted sediment particles and pollutants on the behaviors of sediment.Finally,the future research directions on environmental sediment were proposed,which were the researches of absorption phenomena of organic pollutants at the particles' surface from the microscopic scale,the researches in aspect of scouring and silting of environmental sediment,and the influences of new organic pollutants.
