The element contents in selected bee products from the Lower Silesian region


The quantitative investigation of the elements contents: cadmium, chromium, arsenic, and lead in multiflorous honey, propolis, and pollen (pollen loads) was executed using a plasma spectrometer method (ICP). The bee products were directly taken from colonies in apiaries situated in three regions: Opole, Wałbrzych, and Wrocław. 135 samples of biological material in total were investigated. The investigation results proved that products from the Opole region had the highest content of chromium: from 0.22 in honey to 1.50 mg/kg of dry matters in propolis. However, the arsenic products from the Wrocław region had a chromium content ranging from 0.17 in honey to 0.69 mg/kg of dry matters in propolis. Lead was stated to be a predominant metal in all bee products, its concentrations in propolis (the Wrocław region) reached the level of 18.40 mg/kg of dry matters. Generally it was stated that propolis showed the highest level of metals under investigation and it exceeded the admissible standard levels irrespective of the region of the bee products’ origin. The lowest (except for lead) element contents were found in the bee honey. As for the pollen, it contained medium amounts of trace metals.
