The concentrations of cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) were determined in five (Nettle, Linseed, Pumpkin seed, Sesame, and Chamomile) herbal oil samples, using inductively coupled plasma atomic emission spectrometry (ICP OES) after ultrasonic extraction (UE), wet digestion (WD), and the three- phase emulsion method (TPE). The concentrations for Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn were found to be 0.037-0.064, 0.014-0.085,0.735-1.243, 2.105-19.487, 0.104-0.592, 0.105-1.582, 0.025-0.125, and 1.024-2.583 mg kg1, respectively. The highest concentrations in the herbal oils were Cr, Fe, Mn, and Zn, in linseed oil, Cd and Pb in sesame oil, Cu in nettle oil, and Ni in chamomile oil, respectively. The three sample preparation methods investigated were compared and it was found that the results of TPE and WD are comparable. The statistical results show that the TPE and WD methods usually give similar results.
