Sekundarni naslov:	Cd, Hg, Pb, and As in European species of wild growing forest landscape fungi
Sekundarni povzetek:	Metals, which originate from anthropogenic and natural activities, frequently occur in forest landscape with habitats of many European species of wild growing fungi. The presented review focuses on cadmium (Cd), mercury (Hg), lead (Pb), and arsenic (As) levels in fruiting bodies of wild growing European species of fungi of forest landscape. Furthermore, a comparison with studies of this kind performed in Slovenia was made with the aim to assess themetals levels in fungi from differently polluted areas in Slovenia (the Upper Meža Valley, the Šalek Valley, the Poljana Valley). The usual reported levels for most species grown in unpolluted areas are in the following ranges:Cd: < 0,5 mg/kg - 5 mg/kg dry weight (dw), Hg: < 0,5 mg/kg - 10 mg/kg dw, Pb: < 0,5 mg/kg - 5 mg/kg dw, As: < 0,5 mg/kg -1 (2) mg/kg dw (As), respectively. The presented data reveal that cadmium (Cd) and mercury (Hg) have probably been the most detrimental trace elements in fruiting bodies, which can reach increased levels even in unpolluted areas. It is evident for all analyzed trace elements that values can considerably increase in fungi picked in severely polluted areas. According to data regarding Slovene studies and comparison with other European studies, it is obvious that the Šalek Valley is enriched with Cd and As, while the Upper Meža Valley is considerably polluted with Pb and Cd.

Povzetek (ePrints):	Kadmij (Cd), živo srebro (Hg), svinec (Pb) in arzen (As) so kovine, ki se naravno ali kot posledica človekove dejavnosti pojavljajo v okolju, tudi v gozdni krajini, kjer so rastišča številnih evropskih vrst gliv. Namen članka je bil pripraviti pregled vrst in količin izbranih kovin v trosnjakih gliv ter primerjati lastne raziskave, opravljene v različno onesnaženih območjih v Sloveniji (Zgornja Mežiška, Šaleška in Poljanska dolina), s podatki evropskih raziskav. Vsebnosti kovin v trosnjakih gliv iz neonesnaženih območij praviloma najdemo v naslednjih intervalih: < 0,5 mg/kg do 5 mg/kg suhe teže (Cd), < 0,5 mg/kg do 10 mg/kg suhe teže (Hg), < 0,5 mg/kg do 5 mg/kg suhe teže (Pb) in < 0,5 mg/kg do 1 (2) mg/kg suhe teže (As). Na podlagi pregleda vsebnosti izbranih kovin v trosnjakih gliv ugotavljamo, da sta problematični kovini predvsem Cd in Hg. Omenjeni kovini lahko dosegata velike vsebnosti celo v glivah, ki rastejo v neonesnaženih območjih. Za vse analizirane kovine je značilno, da v trosnjakih gliv iz močno onesnaženih območjih dosegajo velike, celo ekstremne vsebnosti, ki nekajkrat prekoračujejo vsebnosti iz neonesnaženih območij. Upoštevaje primerjavo z evropskimi raziskavami ugotavljamo, da je Zgornja Mežiška dolina obremenjena s Pb in Cd, Šaleška dolina pa s Cd in As.
