Elements were determined using inductively coupled plasma emission atomic spectrometry. Theconducted research showed that the meat of compared breeds differed in the concentrations of Cu, Zn, Fe, Seand K. The meat from Limousin bulls had significantly lower Zn (P<0.001) and Cu (P<0.05) contents thanthat of Red Angus and Salers bulls. Moreover, the meat of Red Angus bulls was characterized by a significantly(P<0.001) lower K content and significantly (P<0.05) higher Fe content compared to those in the Limousinand Salers bulls as well as significantly (P<0.05) higher Se content in comparison with the Salers bulls. Nobreed differences in the concentrations of Pb and Cd were found; however, the Pb concentration in meat washigher than the recommended standards. In the meat of all three breeds, the significant strong positive correlationswere observed between the contents of Pb-Cd, Pb-Ni, Cd-Ni and K-P. The correlations between other elementswithin each of the breeds separately were also found. %U https://ijer.ut.ac.ir/article_785_5a06d47693a1aebb55f076158d51d4d1.pdf
