A total of 45 samples of vegetable oils including soybean and sunflower mixture, sunflower and corn oils (15 each) were examined for detection of the levels of lead (Pb) and cadmium (Cd) before and afler frying. The oil samples were evaluated according to their safety for human consumption based on provisional tolerable weekly intake (PTWI). The olptained nwults revealed that the lead concentrations before frying were ranged fiom 0.0254 - 0.0885, 0.0326 - 0.0577 and 0.0463 - 0.0491 mg/kg for the examined samples, respectively. The cadmium levels before frying were ranged from below detectable limits (BDL) - 0.0016, 0.0007 - 0.0014 and 0.0015 - 0.0029 mg/kg for the examined samples, respectively. Moreover, the results pointed out that a significant decrease in the levels of metals in the examined oil samples afier frying. The concentrations of lead and cadmium were within the maximum permissible limits (MPL). The. results also illustrated that PT WI of the examined samples not exceeded the pCl'II1lSSlbl6 limit fixed for lead and cadmium. The source of metals contamination and public health significance were also discussed.
