Abstract:The aim of this study was to evaluate the content of Lead (Pb), Cadmium (Cd), Copper (Cu) and Iron (Fe) in raw cow’s milk of traditional and industrial sites from 4 different places in Beni Suef Province, Egypt. A total of 72 samples (24 milk samples, 24 feed stuff samples and 24 water samples) were collected from four dairy farms in different cities representing Beni Suef Province, Egypt via subjective sampling method. Samples were prepared, digested then detection and estimation of Lead (Pb), Cadmium (Cd), Copper (Cu) and Iron (Fe) were carried out by using UNICAM 969 Atomic Absorption Spectrophotometer (AAS). There were significant increase in the mean values of Lead, Cadmium and Iron while there was no significant difference in the mean values of Copper in all milk samples of all Districts in comparison with the permissible limit. The comparison of the concentrations of those toxic heavy metals and trace elements in water and feed in different Districts were estimated. In conclusion: High Lead and Cadmium contents of some milk samples from this region might be potentially hazardous to consumers. Further, none of the other tested metals crossed permissible levels.
