Abstract:Heavy metals pollution is a major concern on a global scale. The present work evaluated the cadmium (Cd) and copper (Cu) concentrations in water, soil, forages (Avena sativa, Brassica campestris, Medicago sativa, Pennisetum glaucum and Trifolium alexandrinum), milk and hair samples of cows.
