The aim of our research was to compare the levels of pollution in different habitats based on the concentrations of heavy metals found in pollen and the organisms of Osmia bicornis L. bees in three habitats: orchards, berry plantations, and urban habitats (near by power plant, landfill, residential areas, and heavy vehicle traffic). The concentration of Ag, Cd, Cu, Fe, Mn, Ni, Pb and Zn were determined. Samples were quantified using flame atomic absorption spectrophotometry (AAS), with evaluations being carried out three times for each sample. Bee nests were also analyzed concerning reproduction and the presence of parasites. There were no significant differences in the content of heavy metals Ag, Cd, Cu, Fe, Mn, Ni, Pb and Zn in pollen samples between the three habitat types. Bee samples differed only in their Zn content, which was significantly higher in orchards (2.67 mg/kg) than urban habitats (0.80 mg/kg) and berry plantation (0.94 mg/kg). Habitat type had no effect on most bee reproductive parameters (percentage of occupied nest tubes, population growth). Our results show that bees pollinating crops in, for example orchards or berry plantations are exposed to heavy metals to a similar extent to those urban areas.
