Base metals (Cu, Zn and Pb) as the main resources of the Lower Silesian copper deposits have significantly been influenced by different enviromentalfactors. In this paper, changes in metal concentrations on the surface in relation to deeper layers of the sediments were examined. The concentration ofmetals in the whole sediment, and in selected grain fractions was studied. The contents of these metals in the soils of areas adjacent to the deposit are diverse and are in the range of: 3.0-1082.9 mg/kg Cu; 3.5-106.1 mg/kg Pb; 27.6-49.3 mg/kg Zn, and 1.33-23.0 mg/kg Ni in the old deposit district and Cu 0.91-1655.0 mg/kg Pb; 10.0-1792.0 mg/kg Zn; 3.38-1129.0 and 0.47-32.7 mg/kg Ni in the new deposit district. The increase of metal concentration in the finefractions has been observed. Moreover, the decrease in the metal content with depth was observed in all investigated profiles.
