Abstract
The present study was conducted to estimate the level of concentrations of 12 trace metals and some other chemical element in Local Whey Cheese (LWC) samples, that locally manufactured in southern Iraq and to compare it with the guideline of the World Health Organization (WHO). LWC samples were taken randomly to be digested and the concentrations of dangerous trace metals (Arsenic, Beryllium, Bismuth, Cadmium, Cerium, Copper, Lanthanum, Lead, Nickel,Selenium, Uranium, and Vanadium) were measured using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) device in Zarazma Company for Mineral Studies Tehran – Iran. The results showed statistically significant differrence P <0.05 for the concentrations of the 12 trace metals and some other chemical element in LWC samples. All the studied trace metals and chemical elements recorded low concentrations, consistent with the guidelines of WHO in LWC used, where Selenium recorded the highest concentration (3.47 µg L−1), followed by Vanadium (2.3 µg L−1) and about ( 0.9 µg L−1) for Cadmium, Copper and Uranium. On the other hand, the concentrations of Bismuth, Nickel and Lead metals recorded very low values of (0.1 µg L−1).
