Sažetak
The concentration of Fe, Zn and Cu in ten edible mushrooms in Medvednica Nature Park was determined. The similarity between the studied species was deterimend by cluster analysis based on concentrations of the aforementioned metals in the fruiting bodies. The analyses of heavy metals were carried out by X – ray fluorescence spectormetry. The highest concentration of Fe (153.96 mg kg-1) was determined in Tricholoma portentosum, and the highest concentration of Zn (90.60 mg kg-1) was determined in Tricholoma terreum. The highest concentration of Cu was determined in Macrolepiota procera (78.18 mg kg-1). The concentrations of Zn and Cu significantly differed (p<0.05 ; p<0.001) between examined saprophytic and ectomycorrhizal mushrooms. A considerably higher concentration of the analysed elements was found in the cap than in the stipe for all mushroom species. All mushrooms species were bio-exclusors of Fe in relation to the underlying soils. Cluster analysis performed on the basis of the bioaccumulation of the studied metals revealed great similarity of mushroom species belonging to the same genus and partial similarity of species of the same ecological affiliation.
