The contents of 16 minerals and trace elements (Ag, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Ni, Pb, Pt, Ti and Zn) were analyzed in edible mushrooms (Leccinum scabrum,Boletus edulisandBoletus badius) collected in southwest Poland. Content of Co, Ni and Pb was similar in all tested mushroom species, while content of Ag, Ca, Cd, Hg and Ti was significantly higher inB. edulisthan inL. scabrumandB. badius. The largest differences between these species were observed for Fe and Zn accumulation. The highest contents of these elements were noted inB. badiusbodies (202 ± 88 and 137 ± 24 mg kg−1dry matter, respectively), lower inB. edulis(131 ± 99 and 89 ± 26 mg kg−1dry matter, respectively) and lowest inL. scabrum.Differences in As, Cu and Cr content between tested species were observed mainly betweenL. scabrumandB. badiusfruiting bodies. Content of Pt was below 0.01 mg kg−1dry matter). In the case of Mg and Mn accumulation, differences betweenB. edulisandB. badiuswere not observed (478 and 440 mg kg−1dry matter for Mg and 23 and 19 mg kg−1dry matter for Mn), and the results showed significantly higher content of these elements than inL. scabrumbodies (312 and 10 mg kg−1dry matter, respectively). It is worth underlining that clear accumulation shown by the bioconcentration factor (BCF>1) observed for all three mushroom species was noted in the case of elements Ag, Cd, Co, Cu, Hg, Ni and Zn only.
