Summary
This research examined how Parasol Mushrooms, a popular wild edible mushroom, accumulate various minerals from soil. The study found that these mushrooms can concentrate both beneficial and potentially harmful minerals in their caps, even when growing in unpolluted areas. While they are good sources of essential minerals like potassium and copper, they can also accumulate concerning levels of toxic metals like cadmium, mercury and lead.
Impacts on everyday life:
• People who frequently collect and eat wild mushrooms should be aware of potential toxic metal accumulation
• Moderate consumption of Parasol Mushrooms can provide beneficial dietary minerals
• Environmental pollution can be monitored through mushroom mineral content analysis
• Local food safety guidelines may need to consider wild mushroom consumption patterns
• Understanding mineral uptake by mushrooms helps assess environmental quality
Background
Wild mushrooms can contain various mineral constituents including essential nutrients and potentially toxic metals. The Parasol Mushroom (Macrolepiota procera) is an edible wild mushroom species that grows in woods and pastures. Documentation of trace element composition in wild food is important to understand intake rates and environmental pollution trends.
Objective
To investigate the mineral content, composition and bioconcentration of mineral constituents in Parasol Mushroom growing in Northern Poland. The study aimed to assess contamination status, mineral intake rates, nutritional significance and potential risks to consumers.
Results
The mushrooms showed high bioconcentration of certain elements, particularly K, Ag, Cu, Rb and P in caps with bioconcentration factors between 45-500. Cd, Zn, Mg and Na showed moderate bioconcentration (BCF 3.3-44) while Al, Ba, Ca, Co, Cr, Mn, Ni, Pb and Sr were excluded (BCF < 1). Caps generally contained higher concentrations than stipes. Some toxic metals (Cd, Hg, Pb) were found at levels that could be concerning if large quantities of caps are consumed frequently.
Conclusion
Parasol Mushroom demonstrates high potential to bioconcentrate certain metals from soil into its fruiting bodies, even in pristine areas. While it contains beneficial minerals, the elevated concentrations of Cd, Hg and Pb in caps could pose health risks if consumed in large quantities (300-500g) frequently during mushroom season. Careful consideration should be given to consumption amounts and frequency.
