The concentrations of 6 metallic elements (Pb, Hg, Zn, Mn, Cu, and Fe) were determined in fruiting bodies of 8 mushrooms species and underlying soil samples from Wkrzanska Forest in northwestern Poland. The study included the following species: Russula rosea, Paxillus involutus, Amanita citrina, Boletus badius, Amanita excelsa, Amanita phalloides, Pluteus cervinus, and Hygrophoropsis aurantiaca. The total content of Hg was determined using an AMA 254 Mercury Analyzer. The total content of other elements was determined using an F-AAS iCE 3000 atomic absorption spectrometer. The highest level of bioaccumulation in analyzed species was observed for Zn and Cu, especially in Boletus badius (170.7; 77.81 mg·kg-1 dry weight). Amanita citrina accumulated Pb at the highest level (5.48±3.43 mg·kg-1 dw. in caps). The maximum value of Hg was observed in Boletus badius caps (0.46 mg·kg-1 dw.). Bioaccumulation factors revealed bio-exclusion of Mn, Pb, and Fe (BCFs<1.0). A few positive and statistically significant (p≤0.05) Spearman correlation coefficients of metal-to-metal bioaccumulation in studied caps of macrofungi were observed.
