Understanding the biogeochemical behaviour of selenium in the biosphere is of major concern in ecotoxicology [1] but also in radioecology due to its presence as a long-lived radionuclide (79Se) in the nuclear wastes. In moderately oxidizing conditions like surface soils, selenium exists as selenite (Se(IV)) which can react with mineral particles [2] but also with microorganisms [3]. This study investigated the role of abiotic and biotic processes in the control of Se(IV) mobility in soils.
