Abstract
Aviation turbine oil, motor gasoline, and diesel fuel oil produced in Saudi Arabia were analyzed for concentrations of cadmium and lead. Microemulsion inductively coupled plasma mass spectrometry (ICP/MS) was used in the analysis. Results indicated that the Pb concentration in gasoline, which reached 901 mu g/g, was higher than permitted international values. Lead concentrations in aviation turbine and diesel fuel oil were 0.16 and 0.35 mu g/g, respectively. Cadmium levels in aviation turbine oil, gasoline, and diesel fuel oil were 0.17, 0.085, and 0.01 mu g/g, respectively. Microemulsion ICP/MS proved to be an effective analytical technique for the determination of Pb and Cd in the petroleum products.
