According with this ability, the mushrooms can be used to evaluate and control the level of environmental pollution, but also represent danger for human ingestion. We analyzed some macrofungi species from a wooded area to establish the heavy metal concentrations and ability of bioaccumulation and translocation for Zn, Cu and Sn in fruiting body. The metallic content was established by the Inductively Coupled Plasma-Atomic Emission Spectrometry method (ICP-AES). The minimal detection limits of method is 0.4 mg/kg for Zn and Cu and 0.6 mg/kg for Sn. Heavy metals concentrations in the fruiting body ranged between 6.98-20.10 mg/kg for Zn (the higher value was for Tapinella atrotomentosa); 16.13-144.94 mg/kg for Cu (the higher value was for Hypholoma fasciculare); and 24.36-150.85 mg/kg for Sn (the higher value was for Paxillus involutus). The bioaccumulation factor has important values (higher than 1) only for copper in all the analyzed species (between 1.30 and 8.86) and for tin in Paxillus involutus species (1.19). The translocation factor shows that zinc and tin were accumulated in higher concentrations in cap of mushrooms and the copper had higher concentrations in stipe. ER -
