| Summary: | Background: Honey is a beekeeping product with high nutritional value, considered a bio-indicator of environmental pollution. The aim of this study was to determine the mineral content in honey by analyzing toxic metals in accordance with EU regulations and evaluating the intake of microelements through honey consumption. Methods: Honey samples of different floral origins were subjected to ICP-MS analysis for the determination of toxic metals and metalloids (Cd, Pb, As) as well as microelements (Cu, Zn, Se, Fe, Mn, Co, and Al). The data were considered significant for <i>p</i>-values < 0.05. Results: All analyzed minerals were detected above the limit of detection (LOD) in every sample. Among toxic metals, lead (Pb) levels exceeded the maximum residue limit (MRL) of 0.1 mg/kg, as established by EU Regulation 2023/915, in most samples. However, these levels corresponded to a small percentage of the Provisional Tolerable Weekly and Daily Intake. The concentrations of microelements significantly contributed to the Recommended Daily Allowance (RDA). Conclusions: This study documents the presence of toxic metals in the analyzed honey, with lead (Pb) levels exceeding the MRL. The microelement content provides adequate nutritional intake through honey consumption. Therefore, studying the mineral profile can be used to monitor environmental pollution in the areas where the apiaries are located and to assess the safety of honey. |
