Abstract
This work is made of 5 parts. The first chapter presents the regulatory aspects relative to the polluted sites and soils in France and in Europe in order to allow a better understanding of the stakes of this study. Chapter 2 proposes, first, a bibliographic synthesis of the hydro-mechanical and physico-chemical mechanisms controlling the transfer of pollutants in soils, and then, and exhaustive review of the laboratory tests that allow to evaluate the mobility of pollutants in soils. Chapter 3 is devoted to the experimental study of the interaction between a natural soil and 4 metals (As, Cr, Pb, Zn). It comprises the study of the adsorption-desorption kinetics and the implementation of adsorption-desorption isotherms. This chapter also introduces the notion of speciation (sequential extractions) and shows off the role played by the various constituents of the soil. An experiment of lead-humic acid equilibrium setting-up is proposed to evaluate the phenomenon of complexation on organic matter. Chapter 4 proposes to apply the selected laboratory tests to the previous natural soil artificially polluted in order to characterize the parameters necessary to obtain a mobility scale. The procedures are performed first, on a recently polluted soil and on the same soil after several
