The monitoring of metals and other chemical elements in the basic sources of diet, mainly for children, is very important for preventing health issues. The aim of this work was to determine the concentration of selected essential (Ca, K, Mg, Mo, Na, Zn) and non-mutagenic elements (Ag, Al, Ba, Li, Sb, Sr) in ewe milk from the Orava region in northern Slovakia. Twenty milk samples were analysed in June and August using an inductively-coupled plasma optical emission spectrometry. The differences in elements concentration between the seasonal periods were not significant (p < 0.05), except for lithium (p < 0.05). The essential elements concentration was within the recommended levels, while the non-mutagenic and potentially toxic metals consist was under the permissible limits. However, there were found very strong and significant relationships between the elements which may suggest the synergistic / additive or antagonistic effects of some elements.
