Popis: The aim of this study was to evaluate the mineral composition of different artisanal and commercial honeys from 7 states in Venezuela, considering a simultaneous analysis of major and trace elements by Inductively Coupled Plasma Optical Spectroscopy (ICP-OES), and a comparison among sample pre-treatments including calcination, acid digestion, and dilution. Significant differences were found in the element concentrations between honeys depending on sample pretreatment. Acid digestion was the method selected for the analysis of all honey samples, which proved to be effective and reliable for a simultaneous multi-elemental determination using ICP-OES. The order of average concentration founded for elements in artisanal honeys was: K > P > Mg > Ca > Na > B > Fe > Mn > Ba > Zn > Sr, while for commercial honeys was: K > Na > Mg > P > Ca > Fe > B > Mn > Zn > Sr > Ba. Minerals as As, Cd, Pb, and Hg were not detected in honey samples. The method showed good precision (
