Samples were wet-digested using 3 mL HNO3 and 1 mL HClO4 for 2:15 hours at 210 o C. Selected metals (Mg, Ca, Fe, Mn, Cu, Al, Zn, Cr, Co, Ni, Cd and Pb) were determined by microwave plasma-atomic emission spectroscopy. The validity of optimized procedure was evaluated by the analysis of spiked samples and recoveries were in 90.8-106% range. The mean concentration range (mg/kg) of metal in fruit samples were Ca (1065-36275, 1013-36143), Mg (27- 153, 78.3-139), Fe (103-276, 123-241), Mn (13.5-13.7, 11.5-16.3), Cu (5.13-6.56, 4.11-12.6), Al (77.8-129, 52.5-89.6), Zn (41.3-73.6, 47.4-54.4), Cr (6.15-10.04, 6.57-7.14), Co (6.57-7.14, 1.70-2.35), Ni (1.33-2.37, 1.43-7.66), respectively. Cd and Pb were not detected. Analysis of variance showed significant difference (p = 0.05) in the levels of Cu, Al and Co among sampling sites in green apple fruit while all the other metals did not show significance difference. Red apple fruit showed a significance difference in the levels of Fe, Mn, Cu, Zn, Cr and Co metal while the other metals showed insignificance differences. Pearson correlation coefficients indicated strong, moderate and weak correlation between different pairs of metals in both the green and red apples. © 2021 International Scientific Organization: All rights reserved.

Its fruits mature on shoots that are more than two years old. They mature in late summer or autumn depending on the variety. Apple trees are cultivated worldwide. Apple is a king of all fruits. It is a sweet and edible fruit. It is one of the most favorite and popular fruits ever known. Fruits are essential part of modern diet in almost every society. Fruits and fruit products are known to be good source of nutrients such as minerals and vitamins (Nahar et al., 1990).
