Trace elements and heavy metal contents in West Algerian natural honey

Abstrakt

Analysis of trace elements and heavy metals in honey is essential for honey quality and safety and also monitoring environmental pollution. Tis study aimed to evaluate the composition of thirty-seven honey samples of diferent botanical origins (14 multiforal and 23 uniforal) obtained from beekeepers located in the west region of Algeria. Inductively coupled plasma-mass spectrometry (ICP-MS) and atomic absorption spectroscopy (AAS) methods were used to determine the levels of 19 elements in honey (K, Na, Ca, Mg, Mn, Cu, Fe, Zn, V, Cr, Co, As, Ru, Rh, Cd, W, Pt, Au, and Pb). Ru, Rh, Pt and, Au were not detected in any of the tested honey samples. Te most abundant minerals were K, Ca, Na, and Mg ranging within 153.00–989.00 mg/kg, 33.10–502.00 mg/kg, 13.30–281.00 mg/kg, and 20.80–162.00 mg/kg, respectively. Fe, Mn, Zn, and Cu were the most abundant heavy metals while Pb, V, Cr, W, Co, and Cd were the lowest ones (<1 mg/kg) in the honey samples surveyed. Several honey types, lavender, rosemary, mild white mustard, thyme, milk thistle, carob tree, orange tree, Euphorbia, Eucalyptus, camphor, jujube tree, sage, and harmal, were studied, and the statistical analysis was carried out using principal component analysis (PCA) and hierarchical cluster analysis (HCA) techniques to evaluate the data. Te results showed that the analyses of mineral content were sufcient to determine the foral origin and their variability may be related to geochemical and geographical diferences. On other hand, all elements detected were at levels below safe thresholds.
