TRACE ELEMENTAL ANALIYSIS IN EDIBLE OILS BY USING ATOMICABSORPTIONSPECTROSCOPY (AAS)

ABSTRACT In this research work, a dependable method for the examination of follow componentswas used and concentration ofTrace Elements in the three edible oils samples (Sunflower, Omaar and Hayat edible oils) were obtained by FAASmethod.The samples of the three oils werecollected from the local market and analyzed by FAAS. The accuracy of the reading was determined by spiking experiment and an acceptable percentage recovery was obtained in the range of 92.5 % - 99.50 %. The Cr, Cd, Pb, Zn, Cu and Fe Concentrations were determined in the Sunflower edible oil (0.048, 0.045, 1.932, 2.99, 0.03, and 3.84)mg/kg, in Omaar edible oil (0.067, 0.04, 1.315, 3.265, 0.035, and 2.99) mg/kgand in Hayat edible oil (0.35, 0.37, 2.315, 4.03, 1.182, and 4.44) mg/kg respectively. The results obtained shows that the concentrations of all six trace metals were Maximum in Hayat edible oil sample relative to in the Sunflower and Omaar edible oil samples.Estimated daily and weekly intake of the six trace elements in the three oil samples were less than guidelines provided on the intake of trace element by humans. However estimated daily and weekly intake of Pb and Cd trace element in the Hayat edible oil sample were close to the guidelines provided on the intake of trace element by human. This shows that Cd and Pb might be accumulated through a time in the body of human from continuously use of the studded Hayat edible oil.
