Determination Of Level Of Some Heavy Metals In Honey Collected From Different Regions Of Ethiopia

The qualities of 12 Ethi opian multiflora l honey samples were evaluated in terms ofrncommon phys icochem ical parameters namely: mo isture content, pH, free acidity, lactonicrnac idity and total acidity. The values for studied quality parameters were moisture content,rn14.23-19.2%; pH, 3 A-4 .8; free ac idity, 30.6-97.6 meq/Kg; lactonic ac idity, 8.06-rn14Ameq/Kg and total acid ity, 42.96-107Ameq/Kg. The analyzed samples showed properrnmaturity, absence of undesirable fermentation «20% of moisture content), and were 111rnagreement with standard values (Codex Alimentricus) and reported literatures.rnThe concentrations of trace heavy metals (Cd, Cr, Cu, Mn, Ni, Pb and Z n) in the 12rnmultifloral honey samples collected from different regions of Ethi opia were also eva luatedrnusing flame absorption spectrometry after wet di gestion. The accuracy of the method wasrnassessed by spiking honey samples with known amounts of standard meta ls, andrnexamining recovery. Trace heavy metal contents in the honey samples were found to be inrnthe range of NO-O.O 17 flg/g (Cd), NO-0.15 J.lg/g (Cr), 0.02-1.15 J.lg/g (Cu), NO-7.29 flg/grn(Mn), NO (Ni), NO-2.53 J.lg/g (Pb) and 9.96- 16.03 J.lg/g (Zn). Results obtained were inrnagreement with data reported e lsewhere in literatu re.rnKeyword': Honey, physicochemical parameters, Ethiopia, wet digesti on, ato mic absorptionrnspectrometry, trace e lements
