“…contaminates the global environment and is efficiently accumulated by many "soil" mushrooms. Certain species were found to be particularly efficient at accumulating this contaminant resulting in high and possibly hazardous/toxic, to human, levels of radioactive Cs in the fruiting bodies [1,18,19,45]. At typical concentration, stable Cs levels in foods are nontoxic and, as mentioned, it forms a minor mineral constituent of fruiting bodies.…”

In an attempt to enrich the fruiting bodies with Lithium (Li), this study cultivated mushrooms using growing sets that were fortified with Li2O at 1.0, 5.0, 10, 50, 100 and 500 mg·kg−1 dw. Compost fortification up to 100 mg·kg−1 dw induced a dose-dependent increase in Li accumulation with resulting median mushroom concentrations of 2.0, 8.6, 16, 29 and 38 mg·kg−1 dw, respectively, relative to the unfortified control at 0.087 mg·kg−1 dw. The dose dependency appears to level off as Li2O addition approaches 100 mg·kg−1, suggesting that there is a limit to the ability of the species to accumulate/tolerate Li. Mushrooms did not grow at the 500 mg·kg−1 dw fortification level. At the highest viable level of fortification (100 mg·kg−1 dw), the fruiting bodies were around 440-fold richer in Li content than the control mushrooms. Additionally, the fortification at all levels up to 100 mg·kg−1 dw showed very low, if any, effect on the co-accumulation of the other, studied trace mineral constituents, with concentrations occurring at the lower range of those reported for commercial A. bisporus mushrooms.

“…To obtain an insight into the 210 Po and 210 Pb distribution within the fruitbody, some mushroom samples were separated into cap and stipe during preparation (samples/pools id. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. For these, the results of 210 Po and 210 Pb activity concentrations in the whole specimens were calculated based on the activity concentration and biomass (caps and stipes) percentage share in the fruiting bodies (Table 1).…”

“…The value of Q C/S index > 1 (sometimes also called as distribution ratio, DR) shows that an element is preferentially accumulated in the caps [2][3][4][5][6][7]11,18,19]. The pattern of 210 Po and 210 Pb allocation in the morphological parts may change while ageing (maturing) [20], although mushrooms are generally not consumed when they reach this stage.…”

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.

“…Parameters such as hardness, cohesion and wateriness that are typical for mushroom species can be the major factors determining the leaching rate of radionuclides and other mineral constituents during culinary processing of the fruiting bodies but this aspect has been little studied so far. The typical moisture (water, humidity) content of fresh fruiting bodies of the firmer fleshed B. edulis that are most suitable for consumption is close to 90.0% (Falandysz et al 2021a). Similar values have been reported in other studies (Jaworska and Bernaś 2009;Kenigsberg et al 1996), and this is also the consensus value for wild edible mushrooms, in general.…”

The effects of blanching, blanching and pickling and maceration on the leaching of 137Cs and 40K from the flesh of three edible bolete mushroom species—Boletus edulis, Leccinum scabrum and Leccinum versipelle—were investigated. Significant (p < 0.05) decreases in activity were observed but varied depending on the treatment. Relative to fresh mushrooms, blanching decreased the activity concentration of 137Cs by 15 ± 13%, and of 40K, by 16 ± 7%, but blanching and pickling (vinegar) reduced activity more effectively, by 55 ± 8% and 40 ± 20% respectively. The corresponding losses of 137Cs and 40K through maceration of dried, powdered mushrooms were 38 ± 11% and 35 ± 14% ww, respectively. These results indicate that traditional domestic processing methods may not be as efficient at excluding 137Cs radioactivity as shown in some other studies. The activity concentration of 137Cs in a typically sized (100 g) portion of a processed mushroom (sourced from nearshore regions of the southern Baltic Sea coast near Gdańsk in 2015) meal was projected to be low, i.e. in the range of 0.51 to 12 Bq kg−1 ww. The corresponding effective dose of 137Cs from blanched, blanched and pickled and macerated mushrooms per capita was also assessed to be low, from 0.001 to 0.010 μSv. Nutritionally, the median concentration of potassium (330 mg) in 100 g portions of blanched or pickled mushrooms would account for around 7% of the adequate adult daily intake. Graphical abstract
