Introduction des polluants dans le milieu fluvial sous l'angle du ruissellement des sols

Abstract : Pollutants in the environment are distributed between a particulate "phase" and a "phase" in solution, which can be observed in the soil between organo-mineral particles and interstitial water and, during runoff, between suspended sediment and water. Special attention is given to the different physiochemical processes such as adsorption and degradation, in soils and rivers. Adsorption to soil or sediment particles is particularly important for pollutants are retained, thereby limiting their loss through leaching, though increasing the risk of transfer by erosion. A study of adsorption shows a considerable discrepancy between values established by standard laboratory methods and those measured in situ. This may be due to variable conditions during transport. It is not only the rates of suspended particles and organic matter which are involved ; their composition, size distribution and interactions are also pertinent factors.
