Abstract
The present study was conducted to determine the contamination level of Pb, Cd, Cu,in different types of raw milk and milk products, and to assess their potential health hazards for people using target healthquotients (THQ). Finally, to investigate the removal of cu from artificially contaminated raw milk by using the adsorption properties of a novel chelating ion exchange (CIE) resin.
For the previous purposes, a total of 120 random samples of raw milk of different species and other dairy products (20 samples for each of raw cows’ milk, raw buffalos’ milk, raw sheep’s milk, raw goats’ milk, UHT milk, and kariesh cheese samples) were collected from different outlets and vendors in Sharkia Governorate. All samples were digested and analyzed by Atomic Absorption Spectrophotometer for detection of Lead, Cadmium, and Copper.
Cupper residues in different examined samples :
The concentrations of Cu in different samples varied from 0.009 to 0.81 ppm. The highest mean value of Cu in our work was found in UHT milk samples, while the lowest value was found in raw cows’ milk samples.On the other hand, the Cu residues were higher than the permissible limit (PL) of Cupper, where 65%, 75%, 65%, 75% and 80% of buffalos’ milk, sheep’s milk, goats’ milk, UHT milk, and kariesh cheeserespectively, were exceeded the PL, while no samples of cows’ milk exceeded the permissible limit.
Concerning of Cu, it could be concluded that the average daily intake of Cu from the consumption of different examined samples were relativelylow and represents a low percentage ofADI recommended by The Food and Drug Administration. Also, our results showed that milk.
