The following chemical elements in sheep wool originating from Poland (Polish Mountain Sheep), Greece (Karagounico breed), and Syria (Awassi breed) were analysed: macroelements (Ca, P, Na, K, Mg, S), trace elements (Al, Ba, Co, Cu, Fe, Mn, Mo, Sr, Ti, Zn) and heavy metals (As, Cd Hg, Pb). Some statistically significant differences were observed between the content of the examined elements in sheep wool collected in the above countries.
