Studies of chosen toxic elements concentration in multiflower bee honey
Roman, A., Wrocław University of Environmental and Life Sciences, Wrocław (Poland) | Popiela, E.
The aim of the study was to determine the bioaccumulation level of chosen toxic elements (Zn, Cu, Pb, As and Cd) in multiflower honey collected from Brzeg area. Biological material (honey) was mineralized using the microwave technique at an elevated pressure in the microprocessor station of pressure in the type Mars 5. Quantitative analysis of elements (As, Cd, Cu, Pb and Zn) was performed by plasma spectrometry method using a Varian ICP-AES apparatus. The presence of toxic elements was determined in examined biological materials. The elements fallowed the fallowing decreasing order with respect to their content of honey: Zn more than Cu more than Pb more than As more than Cd. The average concentrations of studied elements observed in multi-flower honey were as follows: 6.24 mg per kg of zinc, 2.75 mg per kg of copper, 0.53, 0.071, 0.042 mg per kg of lead, arsenic and cadmium, respectively. Lead was the most problematic in bee honey because its average content exceeded the maximum acceptable concentration. Additionally, this metal concentration was 60% higher in studied samples than allowable standard of lead content.
