Bee Products as Potencial Bioindicators of Heavy Metal Contamination

摘要

The aim of the study was to determine the bioaccumulation level of Zn.Cu,Pb,Ni and Cd in honey and bee pollen collected from two regions characterized by different degrees of environmental contamination.The samples of each apiary products were collected from stationary apiaries located in industrialized (IN)and non-industrialized (N-IN)areas of Southwest Poland.Quantitative analysis was performed by using Varian ICP-AES plasma spectrometer with controlled mass detection,and CETAC-5000 AT ultrasonic nebulizer.The results showed higher level of all examined heavy metals in both types of bee products in samples from industrialized area in comparison with non-industrialized region.In bee pollen and honey samples from IN area zinc showed the highest concentration: 36.95 mg·kg-1 and 4.58 mg ·kg-1,respectively.Whereas the lowest level was determined in case of cadmium: pollen 0.56 mg·kg-1 and honey 0.14 mg-kg-'.The same tendency was observed in samples from NIN region (bee pollen:Zn 33.63 mg·kg-1,Cd 0.41 mg·kg-1 ; honey: Zn 4.85 mg·kg-1,Cd 0.09 mg·kg-1 ).All heavy metals showed higher concentration in pollen samples in comparison with honey samples.The results of the presented research lead to conclusion that both subjected bee products could be used as bioindicators.It seems however that bee pollen is better bioindicator than honey in respect to environmental contamination.
