Sažetak
Honey is a natural supersaturated sugar solution composed of a complex mixture of carbohydrates. The composition and properties of honey depend on the plants that bees visit and the climatic characteristics of the area from which the honey originates. Honey contains important micro and macro elements, but may also contain potential contaminants. The concentrations of individual metals in different types of honey depend on the presence of elements in the flowers, which is associated with the botanical and geographical origin. Samples of honey from different locations were collected for analysis. In this research, honey samples were analysed for the presence of certain metals. Samples were destroyed by a microwave oven using nitric acid and hydrogen peroxide. The concentrations of elements were determined by inductively coupled plasma mass spectrometry (ICP-MS). The obtained results showed that the concentrations of Cr, Cu, Ni, Cd, and Pb in the analysed samples were less than 1 mg/kg. Concentrations of the other elements were found in the following ranges (mg/kg): Na 64.5-273.5 ; Mg 7.0-71.9 ; Al 34.1-73.8 ; K 265.0-1780.0 ; Ca 40.3-177.0 ; Mn 0.163-1.47 ; Fe 0.71-3.45 ; Zn 0.454-1.49 ; Rb 0.372-2.56 ; Sr 0.086-0.519. Comparing the obtained results on the presence of metals in honey at different locations, it is noticeable that there are differences between the measured concentrations of individual metals, but also between the samples from different locations. From the aforementioned it can be concluded that honey can serve as an indicator of environmental pollution and its geographical origin can be determined by the content of metals.
