Abstract
Safe and quality of food are of primary importance for food industry. The aim of this study was to measure the heavy metals concentration in the raw milk in Mitrovica, a region with a rapid industrial development. Trepca complex, for example is one of the key sources of heavy metal contamination of the region. The purpose of this paper, initially, was to understand the role of food contaminants that until recently were considered as antidote for heavy metals. Samples were prepared in the oven combustion and the remained calyx was treated with nitric acid. Samples were analysed at the atomic absorber and the concentrations of three heavy metals in milk were measured. The results demonstrate that the milk from this area was contaminated with Pb and the highest concentration of this heavy metal was detected during the summer (LV = 2,048 mg/l). The concentration of Zn, one of the essential metals in milk, was reduced to ZD = 0.1506mg/l during winter time. The concentration of Cd, a toxic heavy metal, resulted to be high in all areas, reaching the highest level (BV= 0.1152) in summer.
