Abstract
This study was conducted to determine the residues of Lead (Pb), Cadmium (Cd), and Copper (Cu) in different types of raw milk and dairy products, and to estimate the dietary intake of such metals, as well as to evaluate the potential health hazards of these metals to peoplethrough consuming milk and dairy products. On the other hand, we made a trial to remove copper residues using the adsorption properties of the resin. Therefore, a total of 120 random samples of milk and dairy products, including 80 samples of raw milk of different species from different dairy shops, and farms in Sharkia Governorate, Egypt, in addition to 20 samples for each of UHT milk and Kariesh cheese, werecollected. Pb and Cu residues in the examined samples ranged from 1.85–2.78, 0.009–0.81ppm respectively, while Cd was detected only in raw goats' milk and kariesh cheese samples.Moreover, it is worth clarifying thatPb recorded the highest levels in the examined samples since most of the samples were over the permissible level of 0.1 mg/kg established by Egyptian Standard. Human health risk associated with consuming milk and other examined dairy products was identified using Target Health Quotient (THQ) showed that Pb is the most dangerous element measured in these products as its value was more than one in mostof the samples. In the present study, the performance of IMAC HP resin was assessedfor the firsttime for removal of Cu ions from artificially contaminated raw cows' milk, although it is used extensively to purify water from heavy metals. It was noticed that the removal efficiency of Cu ions increased with higher resin concentration, and increasing time, as the maximum removal percent (76.89%) was achieved by using 0.8 g/L. IMAC HP resin after 45 min. Finally, it was concluded that this type of resin is suitable for the adsorption of Cu ions from artificially contaminated raw milk.
