Investigation of some heavy metals with ICP–MS in afyon buffalo kaymak and skimmed milk

According to industrial development heavy metal pollution affects milk and milk products directly and indirectly. It was aimed to evaluate occurrence of heavy metal in kaymak and skimmed milk, produced from boiled water buffalo milk and obtained from Afyonkarahisar, measurement performed by means of ICP-MS. Totally 50 milk samples were collected from 5 different regions of Afyonkarahisar. To get kaymak and skimmed milk, samples were boiled in beakers under laboratory circumstances. Samples were dissolved according to wet digestion method afterwards quantity of heavy metals were determined by ICP-MS and obtained results were compared with literature values. In the study, average values of chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), molybdenum (Mo), silver (Ag), cadmium (Cd), barium (Ba) and lead (Pb) were determined in clotted cream: 0,36 mg/kg, 0,56 mg/kg, 2,72 mg/kg, 0,08 mg/kg, 0,65 mg/kg, 0,09 mg/kg, 8,27 mg/kg, 0,14 mg/kg, 0,94 mg/kg, 0,00 mg/kg, 0,00 mg/kg, 0,00 mg/kg, 0,17 mg/kg, 0,01 mg/kg; in skimmed milk: 0,02 mg/kg, 0,13 mg/kg, 0,52 mg/kg, 0,02 mg/kg, 0,12 mg/kg, 0,02 mg/kg, 2,37 mg/kg, 0,04 mg/kg, 0,17 mg/kg, 0,04 mg/kg, 0,00 mg/kg, 0,00 mg/kg, 0,13 mg/kg, 0,01 mg/kg respectively. Milk samples of water buffalo collected from different regions of Afyonkarahisar province to get kaymak and skimmed milk had no contamination in terms of heavy metals that may be harmful to human health.
