Assessment of the Impact of Metals in Wild Edible Mushrooms from Dambovita County, Romania, on Human Health

Summary

This study examined 18 types of wild mushrooms commonly eaten in Romania for their metal content and potential health risks. Researchers found that while mushrooms contain valuable nutrients like iron and zinc, some species accumulate toxic metals like lead and cadmium. Adults who eat these mushrooms generally face acceptable risks, but children are more vulnerable due to their smaller body size and higher food intake per kilogram of body weight.

Background

Wild edible mushrooms are widely consumed in Romania as a traditional food and are important sources of essential minerals including iron, copper, zinc, and manganese. However, mushrooms can accumulate toxic metals from soil that may pose health risks to consumers. This study investigates metal content and potential health impacts of wild mushroom consumption in Dâmbovița County, Romania.

Objective

To assess the concentrations of essential and potentially toxic metals (Fe, Cu, Zn, Mn, Ni, Cr, Pb, Cd) in 18 wild edible mushroom species from Dâmbovița County, Romania, and to evaluate non-carcinogenic and carcinogenic health risks associated with their consumption in both children and adults.

Results

Metal concentrations varied significantly among species, with Fe ranging 6.309-88.745 mg/kg, Cu 0.679-3.480 mg/kg, Zn 5.115-25.942 mg/kg, and Mn 0.236-32.025 mg/kg. Adults showed acceptable non-carcinogenic risks but certain species posed elevated carcinogenic risks from Cu, Cr, and Cd. Children demonstrated significant non-carcinogenic risks with hazard indices exceeding safety thresholds for nine mushroom species.

Conclusion

Consumption of wild mushrooms from Dâmbovița County presents variable health risks depending on species and age group. While adults generally face acceptable non-carcinogenic risks, children are more vulnerable to metal accumulation. The results highlight the need for regional-specific compositional data and consumer awareness regarding safe mushroom consumption practices, particularly for vulnerable populations.
