Quantification of mineral and toxic elements in milk of dairy cows by ICP-MS

Abstract

Milk is an important component of mammalian metabolism which included micro and macronutrients. The objective of this study was to survey the concentrations of minerals and toxic elements in cow milk samples by inductively coupled plasma-mass (ICP-MS). In this study, it was analyzed the content of sodium, magnesium, potassium, calcium, titanium, chromium, manganese, iron, cobalt, nickel, copper, zinc, selenium, arsenic, cadmium, thallium, lead in cow milk samples (n=25) collected from Kahramanmaraş province of Turkey. The highest levels recorded for potassium, calcium and sodium with average concentrations of 1587.36, 1157.98, 643.34 mg L-1, respectively. The results revealed that there was no toxic element contamination in cow milk samples. Regular element analysis of cow's milk, which is the most widely used milk in dairy industry, is important for health.
