This study aims to determine the concentration of some essential and toxic mineral elements from four plum varieties harvested from the orchard of the Lugoj area. The metallic elements were determined by the atomic absorption spectrometry method in flame. Phosphorus was determined in the form of molybdenum blue by spectrophotometric method. The obtained results show that the analysed plum varieties ('Record’, 'Vinete românești’, 'Čačanska lepotica’ and 'Stanley’) contain important quantities of essential elements unevenly distributed: 898 - 1.897 mg/kg K, 165 - 429 mg/kg Ca, 119 - 315 mg/kg Mg, 216 - 497 mg/kg P, 3.353 - 4.233 mg/kg Fe, 0.306- 0.726 mg/kg Mn, 0.306 - 1.488 mg/kg Zn, 0.780 - 2.088 mg/kg Cu, 0.032 - 0.198 mg/kg Cr and very small amounts below the lead limits. No significant amounts of Ni and Cd were detected. The results obtained following evaluation of the mineral intake show that, in the present conditions, the degree of coverage of the daily mineral requirement varies in wide limits, depending on the variety of fruit, consumer and the nature of the mineral element.
