Abstract

Cilj ovog rada bio je odrediti koncentraciju kadmija u gljivama Tricholoma spp. (T. columbetta, T. portentosumi i T. terreum) i supstratu tla, usporediti raspodjelu kadmija u anatomskim dijelovima klobuku i stručku, utvrditi prikladnost istraživane vrste gljiva kao bioakumulatora kadmija te procijeniti potencijalne zdravstvene rizike povezane s konzumacijom gljiva roda Tricholoma kontaminiranih kadmijem. Uzorkovanje gljiva vrste Tricholoma spp. i supstrata (tla) provedeno je na devet lokaliteta u Hrvatskoj, od čega pet lokaliteta u središnjoj regiji (Brezova gora, Medvednica, Petrova gora, Maksimir, Dugi dol – Karlovac), a četiri lokaliteta u primorskoj regiji (Ravna gora, Otok krk, Labinština, Skrad). Koncentracija Cd određena je pomoću induktivno spregnute plazme–optičke emisijske spektroskopije (ICP–OES). Najveća prosječna koncentracija kadmija (mg kg-1) utvrđena je u vrsti T. portentosum (0,838), zatim T. columbetta (0,834) i T. terreum (0,791). Vrijednost faktora biokoncentracije veće od 1, ukazuju da odabrane vrste Tricholoma spp. imaju potencijal za nakupljanja kadmija. Utvrđene su veće koncentracije kadmija u klobucima nego u stručcima u sve tri vrste gljiva. Dnevni unos kadmija (DIC < 0,5) i indeks zdravstvenog rizika (HRI < 1) pokazali su da ne postoji potencijalni zdravstveni rizik povezan s konzumacijom odabranih vrsta Tricholoma spp. Rezultati ovog istraživanja korisni su za razumijevanje ponašanja akumulacije Cd kod samoniklih jestivih gljiva Tricholoma spp. prikupljenih iz Hrvatske.

Abstract (english)

The aim of this work was to determine the cadmium concentration in mushrooms of the genus Tricholoma spp. (T. columbetta, T. portentosumi, and T. terreum) and in the soil substrate, to compare the distribution of cadmium in the anatomical parts of the cap and stipe, to determine the suitability of the studied mushroom species as a cadmium bioaccumulator, and to evaluate possible health risks associated with the consumption of Tricholoma mushrooms contaminated with cadmium. Sampling of Tricholoma spp. mushrooms and substrate (soil) was performed at nine sites in Croatia, five of which were located in the central region (Brezova gora, Medvednica, Petrova gora, Maksimir, Dugi dol - Karlovac) and four in the coastal region (Ravna gora, Krk island, Labinština, Skrad). Cadmium concentration was determined by inductively coupled plasma optical emission spectroscopy (ICP-OES). The highest average cadmium concentration (mg kg-1) was found in the species T. portentosum (0.838), followed by T. columbetta (0.834) and T. terreum (0.791). The value of bioconcentration factor were higher than 1, that indicates the selected species of Tricholoma spp. have the potential to accumulate cadmium. Higher cadmium concentrations were found in the caps than in the stpe of all three mushrooms species. The daily cadmium intake (DIC < 0.5) and health risk index (HRI < 1) indicated that consumption of selected species of Tricholoma spp. do not pose a potential health risk. The results of this study are useful to understand the behavior of cadmium accumulation in wild edible mushrooms Tricholoma spp. from Croatia.
