During present investigations the range of most heavy metal residues (mg/L) in milk of cattle and goat have been found higher than their corresponding reported values. Similar trends were observed in meat (muscles and organs) of cattle and goat. The most values of heavy metal residues have been found higher: in goat than in cattle, in Area 1 than in Area 2 and in summer than in winter. Drastic measures are suggested to detoxicate and treat both the industrial and domestic effluents which are intended to be used for agriculture purposes.
