Sažetak
The aim of this work was to determinate the concentrations of chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), cooper (Cu), zinc (Zn) and lead (Pb) from samples of adult bees and bee pupas. Sampling was carried out in apiary located in inhabited destination with intensive agricultural production and main transit roads. All samples were analyzed by Energy Dispersive X- Ray Fluorescence (EDXRF) using MINIPAL4 spectrometer. The presence of heavy metals was found in all examined samples. Mean values concentrations of heavy metals found in adult bees were: 4.609, 21.698, 180.738, 1.366, 16.594, 87.185 and 0.809 ppm, and in samples of bee pupas: 1.351, 7.623, 146.495, 1.222, 7.470, 67.955 and 0.635 ppm for Cr, Mn, Fe, Ni, Cu, Zn and Pb, respectively. Concentrations of iron were the highest, while lead was the least present element in each sample. The high concentrations of heavy metals were determinate in adult bee samples comparing to the samples of bee pupas. That is probably caused by high absorption of pollutants into adult bee bodies during pasturage. The obtained results indicated that heavy metals originated from persistent contaminations of examined area and that a honey bees and bee brood can be useful organisms for monitoring of environmental pollution.
