Abstract

Investigation of honey as a nutritive food material is considered as a bioindiactor of environmental pollution and reflects the status of the surrounding plants, soil and air, moreover its risk assessment is very crucial as it is widely used as a nutritive food substance and a therapeutic agent.
In the current study honey samples were collected from eight different districts in El-Minya province during spring and summer seasons in (2019-2020), they including (El Mahras in Mallawai center, Towa in El Minya center, Demshaw-hashem in Elminya center, Kom-Elloufy in Samalut center, Shosha in west of Samalut center, El-Qees in Beni mazar center, Manshyet menbal in Matay center, and Etledem located in Abu Qurqas center).
A total number of 48 samples were collected from investigated areas including different types of honey (clover, corn, sunflower, anise, marjoram, carawy and basil were collected (6 samples from each site). Samples were collected in dark plastic cubs using plastic gloves and wooden sticks then stored at 4C° till analysis. Samples were prepared for detection and estimation of the following heavy metals (Cu, Fe, Zn, Pb, and Cd) by using Atomic Absorption spectrophotometer. The potential health hazards assessment of heavy metal contamination in honey consumed from the investigated areas were determined through THQ, EDI, and PTWI.
The current results were revealed that that the concentration of the estimated heavy metals (Cu, Fe, Zn, Pb, and Cd) were significantly lower than the recommended permissible limits by the EOS, furthermore Cd element could not be detected. While in comparison the concentration of Pb to the standards of Codex Alimentarius Commission (0.3 ppm), the Pb content of honey samples of Manshet mnbal\ Matay reached to this level, and in comparison to the regulations of the European Commission (2015) (0.10 mg/kg) samples of El qees\Beni mazar, Manshet mnbal\Matay, and Etledem\Abu qurqas areas are considered polluted as the Pb concentration was (0.19, 0.3, 0.25 ppm) respectevly.
Regarding of the health risk assessment of heavy metals contamination in honey consumed, the calculated THQ of Cu, Fe, Zn, and Pb according to their RfDo indicates that there is no carcinogenic risks, moreover the consumption of 19 g honey from the investigated areas as an average daily consumption was reported to be safe for adult and children health in case of all the estimated metals in comparison to the recommended levels except the EDI of Cu was set to be unsafe for children in honey samples from ELmahras/Mallawi, Towa/ELminya, Demshaw hashem/ELminya, Kom ellofy/Samalut and Shosha El gabal/ Samalut, the values were (0.785, 0.633, 0.633, 0.76 and 0.519 5 µg/kg/day) respectevly which exceed the recommended levels (0.05-0.5 µg/kg/day).
In comparison the values of the EWI of the estimated heavy metals in the honey samples to the recommended PTWI we noticed that the values are greatly low in case of adults and children.
