Abstract
Koncentracija željeza, cinka i bakra utvrđivana je u 10 vrsta jestivih gljiva na području Parka prirode Medvednica. Sličnost između analiziranih vrsta ustanoveljena je klaster analizom temeljenom na koncentraciji već spomenutih metala u klobuku i stručku. Analize teških metala provedene su metodom X - ray fluoroscentne spektrometrije. Najviša koncentracija željeza (153.96 mg/kg) utvrđena je u vrsti Tricholoma portentosum, a najviša koncentracija cinka (90.60 mg/kg) u vrsti Tricholoma terreum. Najviša koncentracija bakra utvrđena je u vrsti Macrolepiota procera (78.18 mg/kg). Koncentracije cinka i bakra bile su značajno različite (p <0,05; p< 0,001) između istraživanih saprofitskih i ektomikoriznih gljiva. Znatno viša koncentracija analiziranih elemenata pronađena je u klobuku u odnosu na stručak u svih vrsta gljiva. Sve vrste gljiva okarakterizirane su kao slabi bioakumulatori za željezo. Klaster analiza izvedena na temelju akumulacije proučenih metala pokazala je veliku sličnost vrsta gljiva koje pripadaju istom rodu i djelomičnu sličnost vrsta iz iste ekološke pripadnosti.

The concetration of Fe, Zn and Cu in ten edible mushrooms in Medvednica Nature Park was determined. The similarity between the studied species was determined by cluster analysis based on concentrations of the aforementioned metals in the fruit bodies. The analyses of heavy metals were carried out by X-ray fluorescence spectormetry. The highest concentrations of Fe (153.96 mg/kg) was determined in Tricholoma portentosum, and the highest concentration of Cu was determined in Macrolepiota procera (78.18 mg/kg). The concentrations of Zn and Cu significantly differed (p< 0,05; p< 0,001) between examined saprophytic and ectomycorrhizal mushrooms. A considerably higer concentration of the analysed elements was found int he cap than in the stipe for all mushrooms 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 mushrooms species belonging to the same genus and partial similarity of species of the same ecological affiliation.
