CONTENT OF SOME TRACE ELEMENTS IN FRESH HONEYBEE POLLEN

The aim of the study was to determine the content of arsenic, lead, cadmium and mercury in fresh honeybee pollen. Samples of fresh pollen were collected in a stationary apiary in July and August 2005 and 2006. The samples were to mineralized by microwave method and plasma spectrometry was applied for determination. An average content of the elements was as follows: lead – 0.910 and 0.490; cadmium – 0.239 and 0.265; arsenic – 0.069 and 0.025, and mercury – 0.004 and 0.0036, respectively (in mg/kg dry mass). Lead concentration exceeded permissible standards (0.50 mg/kg dry mass) in 19 samples (n=29) in 2005 and in 10 samples (n=29) in 2006. Concentration of cadmium was high and only in three samples did not exceed the permissible standard (0.05 mg/kg). Concentrations of mercury and arsenic were very low.
