摘要

This paper represents a benchmark study that compares trace toxic elemental concentrations in honey products fromvarious countries to establish a set of guidelines against which subsequent honey analyses could be referenced. Honey isa popular food item, widely consumed as part of a dietary regimen. Honey products originating from nine differentcountries were analyzed for toxic trace elements following microwave digestion in mild acid media (3% HNO3). Acomparative study of this nature has not been previously reported and could provide useful data particularly from anenvironmental and nutritional perspective. High-performance ICP-MS was employed to examine the levels of a range ofnoxious elements in aqueous samples. The performance of the instrument was validated using certified referencestandards. Minor fluctuations in performance were adjusted by use of an internal standard. Sixteen elements wereselected for investigation and the mean concentration ranges are summarized as follows: Li, Be, Ag, Cd, Sb, Hg, Tl, Bi,Th, U occurred in the range 1-25 ?g/L; Pb, Se V, Ni, Cr, Al were observed in the interval 0.1- 4 mg/L. These toxins tendto originate from natural flora associated with the honey or from the chemical processes linked to the production ofhoney. In some samples a€?spikesa€? or elevated elemental levels were observed, which could be used to identify ora€?fingerprinta€? the country of origin of the corresponding honey sample. Our work could be considered a valuable sourceof reference data, and could contribute to environmental, food and forensic science.
