Trace elements accumulating capacity of wild mushrooms are discussing in this paper. Metals such as Ag, Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, were determined using AAS techniques in samples of fruiting bodies of 30 wild-growing mushrooms species. The concentration factors of elements were calculated. Data analyses have shown that some species of mushrooms have a high selective ability to cadmium and silver despite of negligible concentration of these elements in the substrate. B.edilis accumulated cadmium and silver extremely. There were no obvious relationships between the contents of the observed metals in fruiting bodies and the contents of total metals in the upper layer of soil. But the mass fraction of metals depended of the distance from industrial plants and cities.Mots-clés Keywords trace elements, toxic metals, accumulation, wild mushrooms. RésuméLa capacité des champignons sauvages à accumuler les éléments traces est discutée ici. Des métaux tels que Ag, Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, ont été détectés par AAS dans des échantillons de 30 espèces de champignons sauvages (fructi cations). Les facteurs de concentration des éléments traces ont été calculés. L'analyse des données a montré que certaines espèces de champignons ont une capacité d'accumulation très sélective au cadmium et à l'argent, alors que la concentration pour ces éléments est négligeable dans le substrat. B.edilis accumule de façon importante le cadmium et l'argent. Il n'y avait pas de relations évidentes entre le contenu en métaux observés dans les organes de fructi cation des champignons et le contenu en métaux totaux dans la couche supérieure du sol. La fraction massique en métaux est toutefois proportionnelle à la distance aux industries et aux villes.
