“…The mean zinc levels (0.87 and 1.17 μg g -1 w.w.) were lower than those found for Córdoba (Argentina) honeys [25] and Lazio honeys [24] and comparable to those found for San Luis – La Pampa honeys (middle Argentina) [34]. The mean copper levels for our samples (0.18 and 0.29 μg g -1 ) are lower than those of Lazio honeys [24] while Cu was not detected in the Còrdoba (Argentina) honeys [25].…”

BackgroundThe levels of 19 elements (As, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Se, Tl, U, V, Zn) from sixteen different Argentine production sites of unifloral [eucalyptus (Eucaliptus rostrata), chilca (Baccharis salicifolia), Algarrobo (Prosopis sp.), mistol (Ziziphus mistol) and citric] and multifloral honeys were measured with the aim to test the quality of the selected samples. Typical quality parameters of honeys were also determined (pH, sugar content, moisture). Mineral elements were determined by using inductively coupled plasma mass spectrometer (ICP-MS DRC). We also evaluated the suitability of honey as a possible biomonitor of environmental pollution. Thus, the sites were classified through cluster analysis (CA) and then pattern recognition methods such as Principal Component Analysis (PCA) and discriminant analysis (DA) were applied.ResultsMean values for quality parameters were: pH, 4.12 and 3.81; sugar 82.1 and 82.0 °brix; moisture, 16.90 and 17.00% for unifloral and multifloral honeys respectively. The water content showed good maturity. Likewise, the other parameters confirmed the good quality of the honeys analysed. Potassium was quantitatively the most abundant metal, accounting for 92,5% of the total metal contents with an average concentration of 832.0 and 816.2 μg g-1 for unifloral and multifloral honeys respectively. Sodium was the second most abundant major metal in honeys with a mean value of 32.16 and 33.19 μg g-1 for unifloral and multifloral honeys respectively. Mg, Ca, Fe, Mn, Zn and Cu were present at low-intermediate concentrations. For the other 11 trace elements determined in this study (As, Be, Cd, Co, Cr, Ni, Pb, Se, Tl, U and V), the mean concentrations were very low or below of the LODs. The sites were classified through CA by using elements’ and physicochemical parameters data, then DA on the PCA factors was applied. Dendrograms identified three main groups. PCA explained 52.03% of the total variability with the first two factors.ConclusionsIn general, there are no evidences of pollution for the analysed honeys. The analytical results obtained for the Argentine honeys indicate the products’ high quality. In fact, most of the toxic elements were below LODs. The chemometric analysis combining CA, DA and PCA showed their aptness as useful tools for honey’s classification. Eventually, this study confirms that the use of honey as biomonitor of environmental contamination is not reliable for sites with low levels of contamination.

Summary The assessment of geographical origin of honey is economically important for producers and consumers as every region may present particular quality characteristics. In this study, honeys from the seven different regions of Buenos Aires province (Argentina) were characterised by their antioxidant capacity (DPPH, FRAP), total phenolic content (TPC), mineral composition, colour and ash. Honeys showed significant differences among their antioxidant capacity (DPPH), ash, colour and mineral content (P ≤ 0.05). Besides, a good antioxidant activity and low amounts of Cu and Zn (<1.0–1.5 and 0.7–1.8 mg kg−1, respectively) were found in the samples. Significant Pearson's correlations (P ≤ 0.05) among the different parameters were found. Moreover, the linear discriminant analysis allowed the classification of honeys in their original groups with a prediction success of 98%. The present results suggest that honeys could be correctly classified by their geographical origin through their TPC, colour, ash and mineral concentrations.

“…Numerous studies deal with the determination of macro, micro and toxic elements' content in apicultural products (Tuzen et al, 2007;Pohl et al, 2011;Van der Steen et al, 2011;Meli et al 2015), often in order to use them as bioindicators (Jones 1987;Saunier et al 2013;Krakowskaa 2015), to certify their geographical origin (Bilandzic et al 2011;Batista et al, 2012;Bonvehí and Bermejo, 2013;Pellerano 2012;Conti et al, 2014), or to assess the quality of honey (Devillers et al, 2002;Lachman et al, 2007;Pisani et al, 2008). Other studies focus on the use of apiary products for biomonitoring of other environmental contaminants (Balayiannis and Balayiannis, 2008;Bargańska et al, 2016).…”

In the present study, four beehive matrices (honey, propolis, pollen and bees), sampled from thirteen apiaries from Northern and Western Greece, were analyzed for the presence of Cr, Cu, Mn, Fe, Zn, Mg, and Ca. The proposed method involved microwave digestion with H2O2 and HNO3, dilution with water and direct determination by flame atomic absorption spectrometry. The results showed that the levels of elements in all apicultural products present the following order: Ca > Mg > Zn ≈ Fe > Mn > Cu. Cr was detected at LOD level (0.3 μg g ) in pollen and propolis. It was also demonstrated that all detected elements are accumulated at higher concentrations in pollen, propolis and bees and to a much lesser extent in honey. Dependence of the content of Mg in honey and of the content of Zn and Cu in pollen, on the geographical origin of samples was identified.
