“…Thus, sometimes, a relatively elevated concentration of stable Pb observed in mushrooms is due to the high degree of substrate soil pollution [31,32,34]. This does not apply to 210 Pb that typically occurs at low activity concentration levels in mushrooms, as seen in this and other studies [27,[35][36][37].…”

“…studied in other countries. For example, 210 Po and 210 Pb activity concentrations in Finnish mushrooms ranged from 1.38 to 1174 ± 248 Bq•kg −1 db; in German mushrooms, from 1.0 to 640 Bq•kg −1 db; in Norwegian mushrooms, from 4.7 to 198 Bq•kg −1 db; in Chinese mushrooms, from 1.66 to 308 Bq•kg −1 db; while in other Polish species, the range was 0.23 to 36.4 Bq•kg −1 db [12,[21][22][23][24][25][26][27].…”

210Po and 210Pb occur naturally and are the most radiotoxic isotopes of the uranium (U) decay chain. Samples of Boletus edulis and related mushroom species, including B. pinophilus, B. reticulatus, B. luridus and B. impolitus, collected from Poland and Belarus were investigated for the activity concentrations of these isotopes and also for their potential health risk through adult human consumption. The results showed that spatially, the occurrence of 210Po and 210Po was heterogeneous, with activities varying from 0.91 to 4.47 Bq∙kg−1 dry biomass and from 0.82 to 5.82 Bq∙kg−1 db, respectively. Caps and stipes of the fruiting bodies showed similar levels of contamination. Consumption of boletes foraged in Poland could result in exposure to a combined radiation dose of 10 µSv∙kg−1 db from both isotopes. This dose is not significant compared to the total annual effective radiation dose of 210Po and 210Pb (54–471 µSv∙kg−1) from all sources, suggesting that these mushrooms are comparatively safe for human consumption.

“…Thus, weaker uptake and lead (Pb) accumulation from the soil, atmospheric deposition, and higher selenium (an analog of polonium) accumulation influence the value of 210 Po/ 210 Pb activity ratios (Borovička and Řanda, 2007;Vaaramaa et al, 2009;Gwynn et al, 2013). However, higher lead concentrations have been observed in the saprophytic species than the mycorrhizal ones (Ángeles García et al, 2009;Strumińska-Parulska et al, 2021). Some specific geochemical and environmental conditions in the Yunnan soil, e.g., polymetallic soils, hydrology, atmospheric fallout, may also influence the ratio.…”

The dried sclerotium of the fungus Wolfiporia cocos is edible and has medicinal value. This study aimed to understand the accumulation of radioactivity arising from the alpha 210Po, and beta-emitting 210Pb, in the sclerotium’s shell and core and assess a potential effective dose for consumers. Sclerotia were collected in the wild and from cultivars in China’s Anhui and Yunnan provinces. The mean values of 210Po activity concentration levels were 0.36 Bq kg−1 dry weight in the core and 12.0 Bq kg−1 dw in the shell; 210Pb activities were 0.43 and 9.84 Bq kg−1 dw, respectively. The potential effective radiation doses from core layers (as a major raw material of the sclerotium) ranged from 0.13 to 3.43 µSv kg−1 dw from 210Po decay and from 0.11 to 1.52 µSv kg−1 dw from 210Pb decay. Corresponding values for shell ranged from 0.80 to 42.4 for 210Po and from 0.53 to 13.6 µSv kg−1 dw for 210Pb. In general, the intake of W. cocos sclerotia varies between consumers, but this would not significantly change the effective radiation doses from 210Po and 210Pb isotopes. The consumption thus appears to be safe from a radiological protection point of view. Graphical abstract

“…It can be considered as a potential food contaminant due to its prevalence. In the case of Cs and mushrooms, the major problem seems to be due to ongoing contamination with radioactive caesium ( 137 Cs) [ 50 , 76 , 77 , 78 ], rather than with the stable isotope Cs ( 133 Cs) [ 79 , 80 ].…”

“…In B. edulis harvested away from local (anthropogenic) sources of emission, trace elements can be found both of a beneficial and toxic nature in terms of human health, i.e., essential, toxic, radiotoxic, or non-essential elements [ 15 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ]. The artificial radioactive isotopes of caesium ( 134 Cs and 137 Cs) are bio-concentrated by ectomycorrhizal mushrooms and were found at high activity concentrations in the young, button maturity stage, fruiting bodies of B. edulis as well as Amanita muscaria many years after the major contamination events [ 52 , 53 ].…”

The occurrence and associations of Ag, As, Ba, Bi, Cd, Co, Cu, Cs, Hg, Ni, Pb, Rb, Sb, Sr, Tl, U, V, W, and Zn, including data that have not been previously reported on Be, Hf, In, Li, Mo, Nb, Sn, Ta, Th, Ti and Zr, and the sum of (14) rare earth elements (ƩREE), were studied in a spatially diverse collection of the B. edulis caps, stipes, and whole fruiting bodies using a validated procedure with measurement by quadrupole ICP-MS. Toxic Cd and Pb were in B. edulis at concentrations below limits set by the European Union in regulations for raw cultivated mushrooms, while Ag, As, Hg, Sb, Tl, and U, which are not regulated, were at relatively low or typical levels as is usually found in mushrooms from an unpolluted area. The elements Be, Bi, Ga, Ge, Hf, In, Nb, Ta, Th, and W, and also ƩREEs, were found at relatively low concentrations in B. edulis, i.e., with levels from below 0.1 to below 0.01 mg kg−1 dw, and for Ʃ14 REEs, the median was 0.31 mg kg−1 dw. The composite samples of caps showed Ag, Cd, Cu, Cs, Ga, Ge, Hg, Mo, Ni, Rb, Sb, Ti, and Zn at higher concentrations than stipes, while Ba, Co, Hf, Sr, Tl, and Zr were found at higher concentrations in stipes than caps (p < 0.05). Mushrooms were characterized by a low coefficient of variation (CV) of below 20%, between sites for concentrations of As, Cu, Ge, Hg, Ni, V, and Zn, while substantial differences (CV > 100%) were found for Ba, Bi, Co, Hf, Zr, and ƩREEs, and an intermediate variation was found for Sr, W, and U. Principal component analysis performed on mushrooms allowed differentiation with respect to 13 collection sites and separation of a consignment that was specifically contaminated, possibly due to a legacy pollution, with significantly higher levels of Ba, Co, Ga, Li, Nb, Ni, Sr, Th, Ti, Y, Zr, and ƩREEs, and another due to possible recent pollution (Pb-gasoline and also Ni); two due to geological contamination because of the Bi, In, Sc, Sb, Sn, Ta, V and W; and one more, the Sudety Mts. site, which was considered as “geogenic/anthropogenic” due to Ag, As, Be, Cd, Cs, Ni, Pb, Rb, Tl, and U.
