Lublin municipal waste water effluent treated in two stages (mechanical and biological) was used in the monoliths filled with loess soil of an undisturbed structure taken from different erosion zones: W – top (grey-brown podzolic soil): D – bottom of the valley (deluvial soil); N – northern slope (brown soil – weakly eroded), S – southern slope (calcareous soil – strongly eroded). Control objects were the monoliths treated with equal amounts of water and nutrients: N, P, K, Mg. In the soils treated with sewage and water and mineral salts, a similar increase in the content of soluble metal forms (Zn, Cu, Mn, Ph, Cd, Ni) was observed.
