Eighteen honeys collected from various botanical and geographical sources in Tlemcen Province (north-western Algeria) were studied to determine the presence of the following fifteen trace elements and heavy metals: K, Na, Ca, Mg, Mn, Cu, Fe, Zn, V, Cr, Co, As, Cd, Pb and W. Element determination was performed by inductively coupled plasmamass spectrometry (ICP-MS), after digestion, by concentrated nitric acid using microwave mineralizer. The most abundant minerals were K, Ca, Mg and Na ranging within 153-989 mg/kg, 33.1-377 mg/kg, 69.1-162 mg/kg and 13.3-146 mg/kg, respectively. Fe was the most abundant heavy metal followed by Mn, Zn and Cu while Cr, Co, V, W, As, Cd and Pb were the lowest trace elements detected at level < 1 mg/kg in the honey samples surveyed. The variation in the mineral content in the honey samples studied is probably due to geochemical and geographical differences. Multivariate methods were used in order to classify honey samples according to their mineral c...
Determination of Heavy Metals and Potential Health Risk Assessment of Honey
Honey has been used as a bio monitor to determine environmental quality in the environments which are polluted by heavy metals, radioactivity and pesticides. The study sought to determine the levels of some heavy metals (Cd, Cr, Ni, Zn, Cu, Pb, As, and Mn) in honey and assess their potential health risk to consumers. Samples of honey were harvested from within 5km of the Tamale Metropolis of Ghana. A known weight (5g) of honey samples were digested using an oxi-acidic mixture of HNO 3 /H 2 O 2 and filtered into a 50ml volumetric flask. The contents of the minerals in the digests were analyzed using atomic absorption spectrophotometer (AAS). The analysis revealed that the concentrations of lead (79.815 ± 16.796 mg/Kg), nickel (15.785 ± 10.968 mg/Kg), copper (13.855 ± 10.213 mg/Kg) and manganese (8.215 ± 4.452 mg/Kg) in the samples exceeded the FAO/WHO maximum permissible limits. The elevated levels of these metals may be evidence of possible pollution agents (vehicular and industrial emissions, pollution of farm soils and pockets of water) in the study area. The Health Risk assessment (THQ< 1) showed no significant public health risk to consumers. However, we recommend regular monitoring of heavy metals from the natural environment of Tamale to mitigate possible future threats to public health.

The aim of the present study was to assess quality of East Gojjam honey with respect to physicochemical properties and levels of some heavy metals. Three honey samples were collected from Markets of East Gojjam Zone of Amhara Region, Ethiopia and analyzed for some major quality parameters such as pH, electric conductivity, moisture, Total solid, ash content, free acidity, reducing sugar, total sugar, non reducing sugar, total sugar, Hydroxymethylfurfural and color. The results were found to be 3.98-4.12, 0.35-0.65 mS/cm, 17.53-18.19%, 81.8- 82.38%, 0.09- 0.26%, 35.33-46.67 mg/kg, 45.09-63.79%, 61.40-68.11%, 4.30-16.51%, and12.12-23.98 mg/kg, 0.21-0.61 respectively. Significant differences (P<0.05) were observed in pH, moisture content, free acidity, electrical conductivity, ash content, reducing sugar and color of the honey samples from the three different areas. Some of the levels of heavy metal contents were determined by using flame atomic absorption spectrometry (FAAS). The optimized wet digestion method for honey sample analysis was found to be efficient for the metals determined and it was validated through the recovery experiment and a good percentage recovery was obtained (84.45 98.0%).Among the seven heavy metals analyzed for honey Cd and Pb were not detected, hence below the method detection limit. However, the concentration of Fe was found in highest amount with mean concentration ranging from (0.59 to 5.39 μg/g followed by Cr with mean concentration range of (0.22-0.46 μg/g, Cu (0.271-0.278 μg/g, Mn (0.008-0.33 μg/g and Ni (0.04-0.14 μg/g). Significant differences (P<0.05) were observed between Cr, Fe and Mn in all sample sites. The results obtained were in agreement with data reported in the literature and the metals content and the physicochemical properties investigated in honey samples were found within the ranges established by national and international standards, except non-reducing sugar content from Bichena. The slight excess value of sucrose content of honey from Bichena may be due to adulteration of the honey by addition of commercial sugar to honey.

Content of Heavy Metals in Different Types of Honey
International Journal For Research in Applied Sciences and Biotechnology, 2020
The industrialization of agriculture has led to the great use of pesticides, which leads to huge global problems, such as the production of safe food that is safe for humans and the environment. By heavy metals we mean elements whose relative density is above 5 g cm-3, heavy metals can be divided into essential trace elements (Fe, Cu, Zn, Mo, Mn, Ni) and toxic elements (Pb, Cd, Cr, As, Hg). Heavy metals are represented 25% in the soil, and the largest percentage is occupied by K, Fe, Mg, Ca, Al, Na. In addition to anthropogenic processes such as urbanization, traffic, industrialization, heavy metals can be a consequence of natural or pedogenetic processes, ie. inheritance from the parent substrate. The aim of this study was to determine the content of heavy metals Lead and Cadmium in the examined samples, to compare the obtained samples with the norms of the EU and BiH and the influence of the content of heavy metals on the quality of honey. Data collection was performed on the basis of honey analysis of four producers from the area of Tuzla, Lukavac, Živinice and Bihać. The analysis was performed on February 18, 2020. to 25.02.2020. years. The analysis of the processed data was performed in the statistical program IBM SPSS.

Levels of heavy metals in a multifloral Saudi honey
Environmental Science and Pollution Research, 2018
The presence of chemical pollutants, especially heavy metals, affects the quality of honey. The objective of this study was to determine the levels of eight heavy metals (As, Cd, Co, Cr, Cu, Ni, Pb, and Zn) in honey samples from Al-Baha region in Saudi Arabia, using inductively coupled plasma with optical emission spectroscopy (ICP-OES). The highest concentration was found for Zn (1707.93 μg kg −1), while the lowest was found for Co (3.04 μg kg −1). Cluster analysis and principal component analysis showed that two groups are recognized indicating two different metal sources. The first group includes only Zn and the second group includes the rest of the metals. In view of the recommended and established heavy metal intakes for humans, consumption of Saudi honey from Al-Baha should not be deemed a matter of concern for human health.
Determination of some heavy metals in honey from different regions of Ethiopia
Cogent Food & Agriculture, 2020
Honey is an important bee product of greater nutritional value. Ethiopia is one of the main producers of it. Honey is known to accumulate trace metals which are essential as well as toxic. Moreover, as bees collect nectar from flora of nearly in an area of around 100 km radius, the level of toxic metals in honey is an important indicator for environmental pollution by toxic metals. Thus, in this study, the qualities of 12 Ethiopian multi-floral honey samples were evaluated in terms of common physicochemical parameters, namely, moisture content, p H , free acidity, lactonic acidity, and total acidity. The values found were moisture content from 14.23 to19.2 %; p H from 3.4 to 4.8; free acidity from 30.6 to 97.6 meq Kg −1; lactonic acidity from 8.06 to 14.4 meqKg −1 , and Total acidity from 42.96 up to 107.4 meqKg −1. The analyzed samples showed proper maturity, absence of undesirable fermentation, and were in agreement with standard values (Codex Alimentarius

This study aimed to determine the levels and potential health risks posed by trace metals (Zn, Cu, Mn, Cd, Cr, and Pb) obtained in honey samples. The honey samples were from Sheko, Guraferda, Mizan Aman Town, Debub Bench, and Semien Bench in Bench Sheko Zone, Southern Ethiopia, and levels of trace metals were determined using atomic absorption spectroscopy (AAS). The levels of trace metals in honey samples across the provinces ranged as follows; Zn (1.78-4.02 mg/kg), Cu(1.85-2.35 mg/kg), Mn (0.75-1.25 mg/kg), Cd (0.011-0.038 mg/ kg), Cr (0.25-0.55 mg/kg), respectively. The level of Pb was not detected in all honey samples. The levels of trace metals obtained were lower than the maximum permissible limit set by WHO/FAO. Limit of detection (LOD) and quantification (LOQ) were ranged from 0.00045 to 0.005 and 0.0015 to 0.016, for the tested metals, respectively. The estimated recoveries of the method were ranged from 92.66% to 103.00% showed a good agreement of accuracy. The EDI values (mg/kg) of the investigated trace metals in all honey samples were less than the maximum tolerable daily intake (MTDI). The values of the target hazard quotient (THQ) and the hazard index (HI) were less than unity. The target cancer risk (TCR) values of Cd in all honey samples showed the lowest carcinogenic risks with values ranged from 3.34E-07 to 1.27E-06. However, the TCR value of Cr in all honey samples ranged from 1.03E-05 to 2.43E-05 and was in the moderate range. The P TCR value of Cd and Cr ranged from 1.15E-05 to 2.37E-05 and 1.23E-05 to 2.55E-05 for male and female adults, respectively, and were found in the moderate range. Therefore, there was no serious non-carcinogenic and carcenogenic risks to human health from exposure to trace metals through the consumption of this honey.
