摘要：The metal content of fungi’s fruiting body is dependent on species, mode of nutrition and soil properties – pH and metal content. The pH influences the metal bioavailability in a direct way. The studied species are wild growing fungi from Dambovi.a County forestry, in the view of using them in environmental remediation biotechnologies. The sample with young mushroom exemplars from wild were grew in laboratory controlled condition for few days, until the egg mushrooms become a mature fruiting body. During this period the egg mushrooms were sprinkled with CuSO4 solution, 6% concentration and Pb acetate solution, 1% concentrate. By the treatment of mushrooms with CuSO4 and Pb acetate solutions, the concentration of Cu and other elements increase or decrease according with the synergic or antagonistic effect that can have Cu and Pb on the bioaccumulation of other elements. The sample of Boletus edulis treated with CuSO4 solution showed a concentration of Cu in fruiting body over 100 times higher comparing with the blank. For the sample of Russula foetens which was treated with Pb acetate, the Zn concentration increase 2 times, which highlight the synergic effect of lead in soil on the Zn bioaccumulation. The bioaccumulation of Fe, Cu, Zn, Mn and Ni in Cantharellus cibarius, Russula foetens and Lactarius piperatus species is influenced by the Cu and Pb concentration in soil and for Boletus edulis the accumulation is depending on the species metabolism.par
