Bee Pollen Loads Studied for Heavy Metal Content

Concentration of Chosen Trace Elements of Toxic Properties in Bee Pollen Loads
Polish Journal of Environmental Studies, Vol. 18, No. 2 (2009), 265-272

The aim of this study was to determine the rate of bioaccumulation of chosen heavy metals (As, Pb, Cd, Hg) in fresh pollen obtained in the form of pollen loads. The research material were samples of fresh pollen obtained in stationary apiaries located in two regions: agricultural woodland and a former military airfield. Samples were collected in a period of July – August 2005 and 2006. Samples were mineralized by microwave method. Quantitative analysis of examined metals (arsenic, lead, cadmium and mercury) was done using plasma spectrometry (ICP)…

Mercury and arsenic appeared to be metals of toxic properties that do not cause any toxicological problems in pollen from the agricultural woodland and airfield regions since their concentration was very low. High concentration of cadmium in pollen from the agricultural woodland deserves attention. Differences in concentrations of analyzed elements between regions may be used as bioindicators of environmental contamination with elements of toxic properties.
