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.

Abstract (english)

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.
