Chemometric evaluation of trace metals in Prunus persica L. Batech and Malus domestica from Minićevo (Serbia).

The samples of spatial soils and different organs of Prunus persica L. Batech and Malus domestica were analyzed by methods such as inductively coupled plasma optical emission spectroscopy (ICP-OES), Hierarchical Cluster Analysis (HCA), One-way ANOVA, and calculation of biological accumulation factors (BAFs) with the aim of investigating whether these methods may help in the evaluation of trace metals in plants, as well as in the estimation of plant bioaccumulation potentials. ICP-OES provided accurate data on present concentrations of Cu, Zn, Pb, As, Cd, and Ni which showed that most concentrations were in normal ranges, except in some cases for Cu, Zn, and As. HCA illustrated nicely various specifics in the distribution of metals in both investigated systems plant-soil. One-way ANOVA pointed successfully on the existing statistical differences between metal concentrations. Calculated BAFs showed that both plants had very low accumulation rates for all elements; they acted as metal excluders.
