Investigation of the levels of some element in edible oil samples produced in Turkey by atomic absorption spectrometry

The element contents (Fe, Mn, Zn, Cu, Pb, Co, Cd, Na, K, Ca and Mg) in edible oils (olive oil, hazelnut oil, sunflower oil, margarine, butter and corn oil) from Turkey were determined using atomic absorption spectrometry after microwave digestion. The concentrations of trace element in the samples were found to be 291.0-52.0, 1.64-0.04, 3.08-1.03, 0.71-0.05, 0.03-0.01, 1.30-0.50, 84.0-0.90, 50.1-130, 174.2-20.8 and 20.8-0.60 mu g/g for iron, manganese, zinc, copper, lead, cobalt, sodium, potassium, Calcium, and magnesium, respectively. Cadmium was found to be 4.57-0.09 mu g/kg. The high heavy metal and minerals accumulation levels in the samples were found in olive oil for Cu, Pb, Co, margarine for Fe, K, corn oil for Zn, Mn, butter for Na, Mg, sunflower oil for Ca and hazelnut oil for Cd, respectively.
