“…Mushrooms are effective in bioconcentration in fruiting bodies of various metallic elements, semimetals, and radionuclides absorbed by mycelium from soil substrata (Baeza et al 2005; Falandysz et al 2007, 2011, 2014; Kalač 2001; Kojta and Falandysz 2016; Marzano et al 2001), and many species can be highly contaminated by accumulated 137 Cs which was deposited onto forests localized close or more distantly from the source of emission (Grodzinskaya et al 2003, 2013). …”

This study, for the first time, presents the results of activity concentration determinations for 137Cs and 40K in a high number (21 species, 87 composite samples, and 807 fruiting bodies) of mushrooms of the genus Boletus from across Yunnan in 2011–2014 and Sichuan (Boletus tomentipes) using high-resolution high-purity germanium detector. Activity concentrations of 137Cs demonstrated some variability and range from <4.4 to 83 ± 3 Bq kg−1 dry biomass in caps and from <3.8 to 37 ± 3 Bq kg−1 dry biomass in stipes, and of 40K, respectively, from 420 ± 41 to 1300 ± 110 and from 520 ± 61 to 1300 ± 140 Bq kg−1 dry biomass. No significant variations were observed regarding 137Cs and 40K activity concentrations among the same Boletus species from different sampling sites. No activity concentrations from 134Cs were detected in any mushrooms. Internal dose rates estimated were from intake of 1 kg of mushrooms per annum for 137Cs range for species and regions from around <0.0031 to 0.047 ± 0.003 μSv, while those for 40K were from around 0.22 ± 0.04 to 1.2 ± 0.1 μSv. The overall intake of 137Cs was low since low contamination was found in Boletus species.

“…The nuclear weapon tests and Chernobyl accident caused a long-lasting accumulation of the radionuclides with long half-lives in soils and mushrooms. An especially high accumulation was observed for 137 Cs (Bakken and Olsen 1990; Baldini and Nyatemu 1990; Bulko et al 2014; Falandysz et al 2015a; García et al 2015; Grodzinskaya et al 2003, 2013; Mietelski et al 2010). Mushrooms absorb both natural and artificial radionuclides originating from fallout and from soil substrata, and 137 Cs is often a major contaminant but because of species-specific accumulation some other radionuclides can also highly matter for some mushrooms and regions (Steinhauser et al 2014; Kirchner et al 1998).…”

Activity concentrations of 134Cs and 137Cs have been determined in 23 species of mushrooms of the genus Cortinarius (59 individual samples) collected from the Reggio Emilia in Italy 1992–1999 and in 4 species (16 composite samples and 413 individuals) from the Pomerania region in Poland from 1996 to 2015. Across all the Cortinarius species from the Reggio Emilia, the activity concentrations were relatively high in Cortinarius alboviolaceus, Cortinarius duracinus, Cortinarius orellanus, Cortinarius rapaceus, and Cortinarius subannulatus, in which 137Cs was at 10,000 ~ 100,000 Bq kg−1 dry biomass (db) in 1994. Smaller activity concentrations were found in Cortinarius bivelus, Cortinarius bulliardii, Cortinarius cotoneus, Cortinarius largus, Cortinarius lividoviolaceus, Cortinarius purpureus, Cortinarius rufo-olivaceus, Cortinarius torvus, and Cortinarius venetus with levels at 1000 ~ 6000 Bq kg−1 db from 1992 to 1994, and further in Cortinarius anserinus, Cortinarius auroturbinatus, C. largus, Cortinarius praestans, Cortinarius purpurascens, Cortinarius scaurus, Cortinarius sebaceous, Cortinarius talus, and Cortinarius variecolor with activity concentrations at 100 ~ 600 Bq kg−1 db in 1994. All the data were calculated for dehydrated fungal material corrected back to the exact date samples of collection. The greatest activity concentrations of 137Cs both in Italy (1992–1999) and Poland (1996–2010) were found in the popular Cortinarius caperatus, confirming its very high capacity of radiocaesium accumulation. Besides 137Cs, the isotope 134Cs was detected in some species from the Reggio Emilia. An average calculated ratio of activities of 134Cs to 137Cs referenced to 1986 was equal to 0.38 in mushrooms from the Reggio Emilia, and this value slightly differ from that specific for Chernobyl fallout, which was 0.54. It was calculated that 137Cs originating from Chernobyl accident constituted about 68 % of the total activity concentration of the isotope in Reggio Emilia in 1986, while as much as 32 % of 137Cs in mushrooms were from the global fallout from nuclear bomb testing.

“…Emuh (2009) reported that mushroom grows in the presence of heavy metals, secretes enzymesand detoxify such contaminants.Mushrooms are hyper accumulators of heavy metals and radioactive metals thatare toxic to consume and are thus eliminated from the environment. These are bio concentrated in solid forms in the mushroom (Wasser et al, 2003). Lentinula squarrosulusis a wild edible mushroom found in Southeastern Nigeria.…”
