The influence of soil acidification on soil solution content of Mn, Fe, Al, Zn, Cu, Cd, Pb in two soils (cambisol and podzol) taken from heavy industrialized Upper Silesia areas has been studied under laboratory experiment. In both soils decrease in soil pH down to 4.5 and 4.4 caused an increase in the content of studied elements. This increase was higher in podzol than cambisol soil. The highest percent of the element content in soil solution in studied pH range in relation to its total content in the soil showed Cd, then Zn, Cu and the lowest Pb.
