In Turabah province of Saudi Arabia, infant formula and children′s food products were investigated todetermine the concentrations of essential trace elements, namely Mn, Ni, V and Si, and toxic traceelements, namely Al, Ba, Pb, Cd, and As, present in them. Their daily intake amounts were calculatedand compared with provisional tolerable daily intake (PTDI), which was calculated based on theprovisional tolerable weekly intake (PTWI), which was recommended by joint FAO/WHO. The resultsobtained were found to be below the PTDI levels. Some samples exhibited a large amount of Al. ThePTWI of Si and V is not established; however, their concentrations were compared with those reportedin other studies. In some samples, a high concentration of Si was observed. The method employed forevaluation was based on the limit of quantification (LOQ), limit of detection (LOD), and recoverypercent of 92.3–101.6%. Accuracy and precision were employed for evaluating the results
