Human Health Risk Assessment to the Consumption of Medicinal Plants with Melliferous Potential from the Romanian South-Eastern Region

This study presents the impact on human health by consuming medicinal herbs with high melliferous potential (HMPs) from botanical areas with different pollution levels. First, the bioaccumulation of the plants’ parts has been determined. The study assessed the potential health risks associated with the ingestion of various mineral species (macroelements—K, Ca, Mg, Na; microelements—Fe, Mn, Cu, Zn, and one trace element Cd) from three types of HMPs (Sambucus nigra (SnL), Hypericum perforatum (Hp), and Tilia tomentosa (Tt)). The average concentrations of these elements were not similar even in the same type of HMPs. Nevertheless, all samples contained detectable levels of the studied elements. The average concentrations of the studied elements were very low (significantly lower than the legal limit set by the WHO). The study’s findings indicated that the potential health risks associated with ingesting the elements in HMPs were within acceptable limits for children and adults. The hazard quotient (HQ) for Fe, Mn, Cu, Zn, and Cd and the hazard index (HI) for the minerals from HMPs were significantly lower than the acceptable limit (HQ and HI = 1). Similarly, the carcinogenic risk for chemical substances ([Formula: see text]) were lower than or close to the acceptable limit (1 × 10(−4)).
