This study was conducted to determine the residues of Lead (Pb), Cadmium (Cd), and Copper (Cu) in raw milk of different species 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 humans through consuming milk and dairy products. On the other hand, we made a trial to remove copper residues using 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, were collected. Pb and Cu residues in the examined samples were ranged from 1.85-2.78, 0.009-0.81ppm, respectively, while Cd was detected only in raw goat's milk and kariesh cheese samples. However, it is worth to clear that Pb was recorded the highest levels in the examined samples, since most of 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 66.7% of samples. In the present study, performance of IMAC HP resin was assessed for the first time for removal of Cu ions from artificially contaminated raw cow's 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 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.

“…According to the results of the present study, the consumers in Sharkia Governorate will be exposed to a potential health hazard from consuming these products because of the presence of Pb residues, as THQ values of (Pb) >1 through the consumption of all examined samples except, kariesh cheese.While THQ values for Cd and Cu did not exceed one in any of the examined samples. These results were in agreement withthose detected by (Meshref et al, 2014 andGhafari andSobhanardakani, 2017).

“…Milk or milk products can also get contaminated when dairy animals consume contaminated food or graze in industrialized areas or areas with heavy traffic [35, 36]. Some studies have reported serious contamination of some brands of butter and cheese with Pb in Iran [37].…”

BackgroundHeavy metals may be carcinogenic and have serious health effects in humans. In this study, levels of lead (Pb) and cadmium (Cd) in human milk samples from Kerman, Iran were evaluated.MethodsOne-hundred breast milk samples were collected from mothers visiting 20 maternal and child care centers. Demographic, diet and smoking data was collected for each mother. Samples were analyzed by Graphite Furnace Atomic Absorption Spectrometry. Statistical analysis was done in Minitab15, through non-parametric methods, Spearman’s correlation and chi-square.ResultsThe mean ± sd of Pb and Cd was 53.6 ± 64.9 and 8.01 ± 15.5 μg/L respectively. The median (25–75 percentiles) of Pb and Cd was 34.00 (4.00–81.75) and 5.00 (4.00–7.00) μg/L; 6 and 17% of infants were receiving higher than recommended levels of lead and cadmium respectively. Mothers who took fat off their meat before eating and mothers who had a vaginal delivery had higher levels of Cd than others (p value = 0.04, 0.002). Non-primiparous mothers and those who consumed more yogurt had higher levels of Pb (p value = 0.011, 0.025).ConclusionLead and cadmium contamination was considerable among mothers’ in Kerman, Iran. There is a need for decreasing the current levels in food, air, water and other consumer products such as cosmetics.
