Özet

The use of milk as a bioindicator offers valuable insights into the extent of heavy metal exposure in livestock, reflects recent exposure to contaminants and has direct implications for food safety. The present study aimed to evaluate the amounts of heavy metals in water, soil and feed and milk samples of grazing goats and camels. The content of metals is determined using a Flame Atomic Absorption Spectrophotometer. The Copper (Cu) and Nickel (Ni) concentrations in water varied from 0.706 to 1.778 mg/L and 0.099–0.258 mg/L, whereas the values of Cu and Ni in soil collected from two different locations fluctuated between 15.453 and 27.353 mg/kg and 10.513–24.270 mg/kg. The average value of Cu and Ni was noticed in the range of 4.430–10.486 mg/kg and 4.680–12.326 mg/kg in fodder. The mean concentration of Cu and Ni in the goat milk ranged between 0.239 and 0.651 mg/L and 0.666–1.474 mg/L. The values of Cu and Ni in camel milk ranged from 0.457 to 0.934 mg/L and 2.085–3.558 mg/L. This study highlights significant Cu and Ni contamination in soil, water, fodder, and milk, posing potential risks to both animal and human health.
