Metals Contents in Honey, Beeswax and Bees and Human Health Risk Assessment Due to Consumption of Honey: A Case Study from Selected Districts in Khyber Pakhtunkhwa, Pakistan.

Beeswax, honey, and live in-hive worker bees were collected in this study from eight districts in Khyber Pakhtunkhwa, Pakistan. The concentration of seven essential elements (copper, calcium, zinc, iron, nickel, chromium and manganese) and two non-essentials (lead and cadmium) were determined. All of the samples were found to have a random distribution of metal concentrations. The plentiful metals with high concentrations in the gathered samples were discovered to be calcium, iron, and zinc. The health concerns related with metal intake in honey were assessed using the Average Daily Dose (ADD), Hazard Quotients (HQs) and Hazard Index (HI) models. Children were found to have higher estimated health risk values for the components assessed in all samples than adults. All of the computed ADD values were lower than the matching reference (RD) values. The matching HI values of metals in various honeys were found to be less than one, implying that honey consumption in the studied area has no non carcinogenic risk. Cancer risks (CR) was also calculated for intake of Pb, Cr, Ni and Cd in honey in the selected districts. The CR values for Cr and Cd exceeded 1E-4 in various districts such as Karak, Kohat, Nowshera, Bajur, Dir Upper, and Mohmand Agency, signifying that there was a small danger involved. In the case of Karak, the Ni CR value was greater than the allowed limits. As a result, it is important to keep an eye on the concentration of these metals in honey because anthropogenic input could raise their concentration in the future, posing a health danger.
