Potassium, sodium, copper, cadmium, barium, nickel, manganese and strontium residues were determined in thirty eight samples of meat, fat, liver and kidney of both cattle and buffaloe slaughtered at Assiut Governorate during summer 1989-1990. The highest concentration of potassium found to be 21.50 and 21.60 ug/g and 21.60 ug/g dry weight in liver tissue of buffaloe and cattle respectively. Sodium concentrations were high in kidney tissues which reached 13.90 and 14.60 ug/g dry weight in buffaloe and cattle respectively. Copper levels in the livers of buffaloe and cattle were 0.27 and 0.30 ug/g tissue respectively. Cadmium shows the same pattern of distribution in fat, meat, liver and kidneys of both cattle and buffaloe. The highest contents of Nickel were found in fat, followed by kidney, liver and meat in declining sequence. Buffaloe meat, liver and kidneys show higher concentrations of Manganese than that of cattle. Barium and strontium are distributed more evenly among the various tissues of both buffaloe and cattle.
