The aim of the study was to estimate copper (Cu) accumulation efficiency in whole-fruiting bodies of 18 edible and non-edible wild growing mushrooms collected from 27 places in the Wielkopolska Voivodeship. Mushrooms were collected each time from the same places to estimate the diversity in Cu accumulation between tested mushroom species within 3 consecutive years of study (2011–2013). The study results revealed various accumulation of Cu in the whole-tested mushroom fruiting bodies. The highest mean accumulation of Cu was observed inMacrolepiota procera(119.4 ± 20.0 mg kg−1dm), while the lowest was inSuillus luteusandRussula felleafruiting bodies (16.1 ± 3.0 and 18.8 ± 4.6 mg kg−1dm, respectively). Significant differences in Cu accumulation between mushroom species collected in 2011 and in the two following years (2012 and 2013) were observed. The results indicated that sporadic consumption of these mushrooms was not related to excessive intake of Cu for the human body (no toxic influence on health). [ABSTRACT FROM PUBLISHER]

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.

The aim of this study was to evaluate Cd, Co, Cu, Hg, Ni, Pb, Sr and Zn accumulation in six edible mushroom species and to assess their risk and benefits to human consumers. Mushrooms (Leccinium aurantiacum, Xerocomus badius, Lactarius deliciosus, Boletus edulis, Cantharellus cibarius and Suillus luteus) were collected from selected regions of Poland during 1990–2010. The highest diversity between studied mushroom species was observed in terms of Cu and Zn accumulation. Significant differences in the accumulation efficiency were found among the six mushroom species examined. The most efficient were Boletus edulis (Cd and Hg), Suillus luteus (Cu and Sr), and Lactarius deliciosus (Pb and Zn). In the case of Co and Ni, the most effective were Xerocomus badius and Leccinium aurantiacum, respectively. The calculated bioconcentration factor (BCF) values of Cd, Cu, Hg, Sr and Zn were > 1 for all species in this study while Co, Ni and Pb usually were bioexcluded (BCF < 1). Additionally, based on the calculated daily intake rates of trace elements determined it can be concluded that occasional consumption of fruiting bodies of L. aurantiacum, X. badius, L. deliciosus, B. edulis, C. cibarius and S. luteus collected in Poland is safe and this finding largely agrees with results from recent studies by other authors.
