Health risk assessment and micro determination of trace elements content in Egyptian olive oil using ICP-OES

Abstract

Abstract Inductively coupled plasma optical emission spectroscopy (ICP-OES) was applied to investigate multi elements (Zn, Cu, Pb and Cd) of Egyptian olive oil collected from different regions in Egypt. This process involves digestion using 10% nitric acid. The data showed that the concentration ranges were 0.6486-2.4166 μg/g, 0.0092-0.6919 μg/g, 0.0185-0.1026 μg/g and 0.0009-0.0186 μg/g for Zn, Cu, Pb and Cd, respectively. The results indicated that the highly toxic metals content did not exceed that recommended by FAO/WHO. The proposed method exhibited an excellent accuracy, adequate selectivity and high sensitivity. For the first time, this method described the direct determination of the previously mentioned elements and investigated the effect of both temperature and time for different samples in Egyptian olive oil.
