Abstract:
The heavy metals (Zn, Fe) content of some wild mushrooms (Amanita caesarea, Rusulla virescens, Rusulla
cyanoxantha, Rusulla vesca, Rusulla alutacea, Rusulla foetens, Lepiota procera, Lepiota excoriata, Armillaria mellea,
Cantharellus cibarius, Boletus edulis, Pleurotus ostreatus, Hydnum repandum, Lactarius piperatus, Lactarius
vellereus) of four sites from Dambovita county Romania, were analyzed. Elements concentrations were determined by
Energy Dispersive X-ray Fluorescence spectrometry (EDXRF). In fruiting body of these mushrooms, the highest mean
concentration of macroelements was found for Zn and Fe. Hydnum repandum species accumulated zinc at a level three
times higher than average concentration of species of fungi studied, 248 mg/kg and Cantharellus cibarius species
concentrate the metal values of two times higher than average concentration. Rusulla cyanoxantha species
concentration values of iron is four times higher, respectively Chantarellus cibarius, Lactarius piperatus species have
values three times higher than average concentration of this metal. We can say that these three species of this metal are
good bioaccumulation, developing normally, even at high concentrations of iron.
Peroxidase activity of fungi was determined in order to find correlations between the size of oxidoreductase activity and
concentration of heavy metals. Enzymatic activity was enhanced by higher concentrations of metals accumulated in
most species studied macromycetes.
