Abstract
The presence of some essential and non-essential trace elements in stingless bee honeys raises public health concerns, even though research evaluating these honeys is scarce. A comparison was made of the concentrations of 11 potentially toxic trace elements in honey samples from five stingless bee species collected in two states in Brazil. Trace elements were quantified by ICP-OES. The average concentrations (mg.kg−1) of trace elements were: Al (1.728), Mn (1.301), Zn (1.071), Cu (0.471), Sn (0.372), Sr (0.366), Ba (0.299), Sb (0.245), Ni (0.047), Co (0.013) and Cd (0.008). The results indicated that honey from Paraná (South region) contained higher levels of Ba and Co, while honey from Rondônia (Amazon region,) had the highest concentration of Sb. The variation in the results may not be related to the bee species’ behaviors, but rather to their foraging territory to collect nectar/pollen and the type of plants and flowers visited. This observation allows considering honey as a good indicator for monitoring environmental contaminants. The results of the health risk assessment based on the consumption of the honey samples collected in the two evaluated states did not indicate carcinogenic risk due to lifetime consumption of the products.
期刊介绍:
The Journal of Food Composition and Analysis publishes manuscripts on scientific aspects of data on the chemical composition of human foods, with particular emphasis on actual data on composition of foods; analytical methods; studies on the manipulation, storage, distribution and use of food composition data; and studies on the statistics, use and distribution of such data and data systems. The Journal''s basis is nutrient composition, with increasing emphasis on bioactive non-nutrient and anti-nutrient components. Papers must provide sufficient description of the food samples, analytical methods, quality control procedures and statistical treatments of the data to permit the end users of the food composition data to evaluate the appropriateness of such data in their projects.
The Journal does not publish papers on: microbiological compounds; sensory quality; aromatics/volatiles in food and wine; essential oils; organoleptic characteristics of food; physical properties; or clinical papers and pharmacology-related papers.
