The effect of two manganese dioxides on the uptake of lead, cobalt, nickel, copper and zinc by subterranean clover

Abstract

The uptake of lead, cobalt and to a lesser extent nickel by subterranean clover grown in pots on lead-contaminated soils was reduced by the addition of two varieties of manganese dioxide, while there was little or no effect on the uptake of copper and zinc. The results were consistent with the previously determined distribution of these elements between the manganese and iron oxides in soils.
