Two soil samples polluted by sewage sludge or atmospheric deposition were mixed with hydroxylamine hydrochloride as reducing agent, in order to simulate anoxic conditions able to occur in natural medium, thus evaluating the reactivity of trace metals. Metal extractability in reducing conditions was...
