The study was aimed to compare concentrations of trace elements in the wool of Merino ewes grazing on the pastures polluted and unpolluted with industrial emissions. As, Ba, Cd, Cu, Co, Cr, Fe, Mn, Mo, Pb, Si, Sr, Ti and Zn were examined. Significant differences concerned 11 elements: As, Ba, Cd, Co, Fe, Mn, Mo, Pb, Si, Ti and Zn. Manganese in polluted and unpolluted environment amounted respectively to: 3.682 and 0.059 mg.kg-1 dry matter; Pb 6.937 and 0.495; Fe 21.661 and 2.563; Cd 0.543 and 0.074; Co 0.186 and 0.046; Ti 2.353 and 0.640; Mo 0.125 and 0.048, Si 111.30 and 55.86, As 0.047 and 0.029, Zn 224.73 and 140.21 and Ba 4.687 and 2.996; Cu 7.23 and 4.33, Sr 9.303 and 8.179, Cr 0.047 and 0.046. According to a descending order of the values in both groups Zn and Si occupied the same first and second position and As the 14th one.
