ABSTRACT
Natural and anthropic patterns can create reductive conditions in soils, which can lead to the dissolution Fe and Mn oxyhydroxydes, possibly releasing associated other heavy metals. Laboratory batch experiments were conducted with a polluted soil as a function of pH, in the presence and in the absence of hydroxylamine as reducing agent. Pb and Cd are solubilized under mildly reductive conditions but Pb is efficiently removed from solutions by remaining solids.
