Uršulin-Trstenjak N., Levanić D., Primorac L., Bošnir J., Vahčić N., Šarić G. (2015): Mineral profile of Croatian honey and differences due to its geographical origin. Czech J. Food Sci., 33: 156-164.The proportions of twelve minerals were determined in 200 samples of the black locust honey from five Croatian regions during two seasons. The average proportions were dominated by that of K (205.57-428.05 mg/kg), followed by Ca (33.53-329.00 mg/kg) and Na (23.34-218.04mg/kg), which was in percentages as follows: K 31.69-81.34%, Ca 6.51-35.56%, and Na 7.36-23.65%. Melissopalynological and physico-chemical analysis of honey confirmed its general quality requirements and botanical origin. One-factor analysis of variance showed a significant differences between the regions in each season based on the average proportions of macro and micro elements except for Mn and Cd in season 2 (P < 0.05). t-Test enabled an insight into the significance of differences between the seasons within each region based on the average proportions of macro and micro elements. Principal components analysis (PCA) showed that Al (Bjelovar-Bilogora), Fe (Bjelovar-Bilogora and Istria), Cu (Eastern Croatia), and K (Istria) could present mineral substances typical for the black locust honey of each region.

“…Honey is the result of a bioaccumulation process useful for the collection of information related to the environment where bees live. Honey has been recognized as a biological indicator of environmental pollution (Celli & Maccagnani, 2003;Rashed & Soltan, 2004;Muñoz & Palmero, 2006). As a food stuff used for healing purposes, honey must be free of any objectionable content and should contain only small amounts of pollutants, such as heavy metals (Jarić, 2011).…”

Trace elements and heavy metal residues in honey samples originating from different regions of Bangladesh were determined. High mineral contents were observed with Ca, and Fe being the most abundant. The concentrations of the trace elements were within the recommended limits, indicating that the honeys were of good quality. Pb was present in trace amount which is not harmful for consumption where Arsenic was absent. Clostridium perfringens spores were not found in the analyzed honey samples.

“…A distinct strategy for the analysis of metals through electrochemical techniques was proposed by Muñoz and Palmero [54]. Specifically, honey samples were diluted in hydrochloric acid, a solution to which gallium nitrate was then added to decrease any interferences that could complicate adequate zinc measurements.…”

“…This method provided better results not only for zinc, but also for cadmium and lead in the assessed honey. The primary advantage of the technique proposed by Muñoz and Palmero [54] is that digestion through H 2 O 2 was not used. Nevertheless, this technique was unable to measure elements such as copper, thus limiting its widespread application.…”

Metals are pollutant residues detectable in honey and in fact account for most of the inorganic pollutants found in this food product. Metal pollutants can be accumulated through the food chain and, at levels exceeding safe thresholds, can be toxic to humans and even damage physiological functions. During the honey-making process, bees can transport pollutants to the beehive following contact with polluted botanic species or from drinking contaminated water. Detecting very low concentrations is a persisting challenge to accurately measure these elements in honey. Additionally, since honey is a complex organic matrix, treatments are needed prior to applying any classical chemical methods for metal determination, such as inductively coupled plasma and atomic absorption spectroscopy. Therefore, optimal results are dependent on adequate sample conditioning prior to heavy metal content analyses. Chemical pretreatments include calcination processes and/or acid digestion. Regarding execution, the last steps of any metal detection methodology are the primary determinants of result quality, where any loss of mass is reflected by unreliable values.
