In the present paper we investigated contents of heavy metals (As, Pb, Cd and Hg) and health damaging substances (nitrates and nitrites) in fruits of apple Idared grown on different localities in the Čačak region. The cultivar dominates local commercial apple plantings and is the leading apple cultivar produced for both export and domestic markets. Therefore, control of sanitary and health status of produced apple fruits is of key importance. Arsenic (As) content in apple fruits varies among localities, ranging from 0.0035 mg/kg to 0.0071 mg/kg, variation coefficient being from 4.51% to 36.82%. Lead (Pb) content ranged from 0.0035 mg/kg to 0.0807 mg/kg, its variation coefficient being 4.51-11.44%. Cadmium (Cd) and mercury (Hg) contents were within the range 0.0028-0.0059 mg/kg and 0.0058-0.0076 mg/kg, respectively, their variation coefficients varying by localities between 6.11% and 37.10% and 6.03% and 23.67%, respectively. Nitrates and nitrites content in all samples was bellow 3mg/kg of fresh fruit weight. The established contents of heavy metals, nitrates and nitrites were considerably lower than prescribed by Regulation. The obtained results infer that the growing region above is very suitable for commercial apple production in the studied parameters.
