Abstract: | Concentrations of Fe, Mn, Zn, Pb, Cu and Cd in soil solutions taken in the vicinity of a sulphur mine range from 354 to 9080
μM L−1, and exceeded the concentrations measured in solutions from light acid arable soils. The content of each metal was a negative
function of either the solution pH or of Ca concentration.
Reclamation of S-contaminated soil by an application of 2000 tonnes of limestone per hectare did not significantly affect
the solubility of trace metals, whereas equilibration of soil samples with CaCO3 in the laboratory decreased solubility of metals, especially in the soil under moist conditions.
Sulphur deposition may modify the natural cycling of metals in soils. |
