Abstract :Milk and various dairy products are among the basic foods used in nutrition. However, milk and dairy products can contain many environmental pollutants such as pesticides, detergents, drug residues, heavy metals that may pose technological risks and are dangerous for human health. The aim of this study is to reveal the change of the amounts of essential elements and heavy metals in sheep`s milk and yoghurt, buttermilk and butter which produced from the same milk. For this purpose, yoghurt, buttermilk and butter were made from sheep`s milk. Then, in milk and dairy products, Sodium insert ignore into journalissuearticles values(Na);, Magnesium insert ignore into journalissuearticles values(Mg);, Potassium insert ignore into journalissuearticles values(K);, Manganese insert ignore into journalissuearticles values(Mn);, Copper insert ignore into journalissuearticles values(Cu);, Zinc insert ignore into journalissuearticles values(Zn);, Arsenic insert ignore into journalissuearticles values(As);, Selenium insert ignore into journalissuearticles values(Se); );, Cadmium insert ignore into journalissuearticles values(Cd);, Lead insert ignore into journalissuearticles values(Pb); amounts were examined by ICP-MS. The amount of As, Cd, Pb in all samples were determined under the limit of detection insert ignore into journalissuearticles values(LOD);. The amounts of Na, Mg, K, Mn, Cu, Zn, Se in milk were determined as 785, 92, 1537, 30.8, 73.5, 2683.5, 381.5 ppb, respectively. The amounts of Na, Mg, K, Mn, Cu, Zn, Se in yogurt were determined as 554.5, 121.5, 1516.5, 29.3, 71.5, 3692, 405 ppb, respectively. The amounts of Na, Mg, K, Mn, Cu, Zn and Se in ayran were determined as 40175, 56.5, 553.5, 111.5, 1230, 2506.5, 447 ppb, respectively. The amounts of Na, Mg, K, Mn, Cu, Zn, Se in butter were determined as 98.2, 31.7, 223.1, 10.1, 24.6, 203.5, 282.5 ppb, respectively. According to these data, changes in the amount of essential elements were observed when milk was transformed into its products. It was determined that there were no heavy metals in sheep milk and products grown in this region.
