Abstract
The aim of this study was to determine the heavy metals (As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn) from honeys (acacia, sunflower, tilia, and polyfloral) from different counties (Suceava, Botosani, and Vaslui) of the northeast region of Romania. The data were analyzed using principal component analysis and linear discriminate analysis in order to achieve useful models for classification of honeys according to their botanical and geographical origin using the heavy metals content. The heavy metals content can be used as a suitable tool for the classification of honeys according to their botanical origin (80.8% were correctly classified), but not for the geographical origin (only 21.2% were correctly classified). None of the 10 heavy metals analyzed exceeded the maximum allowable level.
