The Bioaccumulation of Some Heavy Metals in the Fruiting Body of Wild Growing Mushrooms

Due to their effective mechanism of accumulation of heavy metals from sod, the macrofungi show high cocentrations of metals in their fruiting body 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 04 mg/kg for Zn and Cu and 06 mg/kg for Sn Heavy metals concentrations in the fruiting body ranged between 6 9820 10 mg/kg for Zn (the higher value was for Tapinella atrotomentosa),16 13-14494 mg/kg for Cu (the higher value was for Hypholoma fasaculare). and 24 36-150 85 mg/kg for Sn (the higher value was for Paxillus involutus) The bioaccumulation factor has important values (higher than I) only for copper in all the analyzed species (between 1 30 and 8 86) and for tin in paxillus involutus species (I 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 stye
