The concentrations of minor and major (Cd, Cr, Cu, Fe, Mn, Pb, Zn, Ca, K, Na and Mg) elements were determined in six apple varieties (Florina, Golden Delicious, Idared, Jonathan, Prima and Starkrimson). The apple samples were collected from an orchard located in the North-West region of Romania, Cluj County, during September 2011. The analytical method for the determination of selected elements in apple consists in microwave acid digestion followed by inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma optical emission spectrometry (ICP-OES) measurement. In all samples, of all the investigated minor elements, iron was found to be the dominant element (4.64 mg/kg). The increasing order was: Mn
