Results of the statistical analysis showed that there was a significant differences ( p˂0.05) in levels of Cadmium (Cd) and Lead (Pb) among the studied animals, the highest level of Cadmium and Lead were (0.251 and 0.801) mg /L respectively for sheep milk and the lowest values (0.098 and 0.311) mg / L respectively for cow's milk, and also shown significant difference (P<0.05) among different regions where the highest level of Cadmium and Lead were (0.184 and 0.624) mg / L respectively for AL-Hamza district and the lowest level were (0.144 and 0.507) mg / L respectively for AL-Daghara region.
