Trace metal contents and quality parameters (physicochemical properties) such as pH, electrical conductivity and ash content of four Ethiopian honeys were determined using flame atomic absorption spectrometry, pH-meter, conductivity meter and ashing, respectively. The optimized wet digestion method for honey analysis was found efficient for the metals determined and it was validated through the recovery experiment and a good percentage recovery was obtained (93-104%). Fe was found in highest amount with mean concentration ranging from 5.37 to 12.4 μg/g followed by Ni with mean concentration range of 0.80 to 4.46 μg/g, Cr (1.20-4.33 μg/g), Zn (1.92-4.22 μg/g), Co (0.60-1.17 μg/g), Mn (0.16-0.89 μg/g), Cd (ND-0.69 μg/g) and Cu (0.09-0.47 μg/g). The toxic metal Pb was not detected. The ranges of physicochemical properties determined were summarized as: pH 4.11-4.33, electrical conductivity of 0.10-0.29 mscm-1 and ash content 0.17-0.46%. The metals content and the physicochemical properties investigated in honey samples were found within the ranges established by national and international standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
