Regards to the extent of the As pollution in the world and its impact on human health, the processes controlling its dynamic had to be investigated, especially in wetlands, recently recognized as potential As source for groundwater. The objective of this work was to study the oxidation products of a wetland and the associated As speciation. In a first part, natural oxidation products collected in a wetland soil (Naizin-Kervidy, France) were studied. The solids analyzed by XAS showed that As was partially oxidized. The As (III) persistence was explained by the control exercised by MO on the Fe bearing phases of As responsible also for its oxidation. Iron formed nano-oxides, small polymers or monomers complexed to organic molecules. The small...
