ABSTRACT
The presence of essential elements in milk is vital for the nutrition of human beings and also all mammalians, particularly infants. The aim of this study was to determine the concentrations of copper in cow’s and sheep’s milk by inductively coupled plasma-mass spectrometer (ICP-MS) after microwave-assisted digestion with nitric acid and hydrogen peroxide. Between February 2017 to July 2017, 21 cow’s milk samples and 40 sheep’s milk samples were gathered from two different regions of Harran lowland. The mean concentration of copper in cow’s milk samples were 97.21 ± 6.33 ppb and in sheep’s milk samples were 135.13 ± 31.05 ppb, respectively. It was seen that there was a statistical difference between the levels of copper in cow’s and sheep’s milk. The data revealed that copper levels in sheep’s milk were higher than the cow’s milk. ICP-MS method of this study could provide a sensible alternative for the element characterization of milk samples.
