“…Emphasis is frequently given on long-lived 137 Cs that polluted the surface of the Earth due to global radioactive fallout after testing of nuclear weapons and from nuclear power plant accidents, but some others as well as naturally occurring radionuclides are also intensively studied in mushrooms (Horyna and Řanda 1988; Bakken and Olsen 1990; Tsvetnova and Shcheglov 1994; Dahlberg et al 1997; Kirchner and Daillant 1998; Rühm et al 1997; Skwarzec and Jakusik 2003; Strandberg 2004; Baeza et al 2004a, b; Kostiainen 2007; Vaartamaa et al 2009; Mietelski et al 2002, 2010; Taira et al 2011; Vinichuk et al 2011; Castro et al 2012; and many others).…”

“…Radiocesium ( 137 Cs) is the nuclide on which public interest is mainly focused and it is widely studied in wild-grown mushrooms (Kirchner and Daillant 1998; Baeza et al 2004b, 2005; Mietelski et al 2002, 2010; Kostiainen 2007; Taira et al 2011; Castro et al 2012; and many others). The 137 Cs and other nuclides deposited from fallout are further absorbed by fungi from soils (decaying litter and organic and inorganic soil layers—elements diffused into soil solution), and there is no discrimination between decaying and stable isotopes of a particular element undergoing uptake by mycelia.…”

This article reviews and updates data on macro and trace elements and radionuclides in edible wild-grown and cultivated mushrooms. A huge biodiversity of mushrooms and spread of certain species over different continents makes the study on their multi-element constituents highly challenging. A few edible mushrooms are widely cultivated and efforts are on to employ them (largely Agaricus spp., Pleurotus spp., and Lentinula edodes) in the production of selenium-enriched food (mushrooms) or nutraceuticals (by using mycelia) and less on species used by traditional medicine, e.g., Ganoderma lucidum. There are also attempts to enrich mushrooms with other elements than Se and a good example is enrichment with lithium. Since minerals of nutritional value are common constituents of mushrooms collected from natural habitats, the problem is however their co-occurrence with some hazardous elements including Cd, Pb, Hg, Ag, As, and radionuclides. Discussed is also the problem of erroneous data on mineral compounds determined in mushrooms.Electronic supplementary materialThe online version of this article (doi:10.1007/s00253-012-4552-8) contains supplementary material, which is available to authorized users.

“…These values, when compared to those reported in the present study (B. edulis with 88.1 765.4 Bq kg À 1 dw and C. cibarius with 73.4 7119 Bq kg À 1 dw), were found to be significantly lower. Castro et al (2012) analyzed edible mushrooms in Sao Paulo (Brazil), concluding that the minimum detectable activity concentration (MDC) of 137 Cs was 7.3 Bq kg À 1 . This activity concentration of 137 Cs varied from 1.45 70.04 to 10.6 7 0.3 Bq kg À 1 (dry weight), from 1.77 0.1 to 6.0 70.2 in the case of L. Edodes, and from 3.6 70.1 to 6.7 70.2 in P. ostreatus.…”

“…Different fungal species also exhibit widely varying degrees of 137 Cs contamination; however, saprophytic mushrooms tend to have lower TF of 137 Cs than symbiotic mycorrhizal fungi (Yamada, 2013). Bazała et al (2008) and Castro et al (2012) state that the longevity and the wide mycelium of mushrooms make them excellent environment bioindicators. 40 K,137 Cs,226 Ra and 228 Ra are among those radionuclides that can be accumulated by mushrooms.…”

This study pres ents the con cen tra tions of radionuclides and heavy met als in twenty-six ta ble ol ive (Olea europaea L.) sam ples, and an as sess ment of the health risks as so ci ated with their con sump tion. The sam ples were col lected from dif fer ent towns in the Med i ter ra nean re gion of Tur key, one of the ma jor ol ive-pro duc ing coun tries in the world. The av er age ac tiv ity concen tra tions of 226 Ra, 232 Th, 40 K, and 137 Cs in the ed ible parts of the ta ble ol ive sam ples were found as 37.9 ± 4.1, 7.1 ± 0.5, 274.6 ± 14.7, and 7.2 ± 0.7 Bqkg (dw), re spec tively, by us ing a gamma ray spec trom e ter. The ef fec tive ra di a tion dose due to the in take of these radionuclides through in ges tion of ol ive sam ples var ied from 3.4 to 22.7 mSv with an av er age value of 11 ± 1 mSv. The av er age con cen tra tions of Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, and Pb in the ed ible parts of the ta ble ol ive sam ples were de ter mined as 2.04, 11.08, 166.60, 0.20, 10.29, 13.81, 14.34, 4.50, and 4.55 mgg-1 , re spec tively, by us ing an in duc tively cou pled plasma op ti cal emis sion spec trom e ter. Based on the mea sured con tent of the radionuclides and heavy met als, the re sults im ply that ta ble ol ives are safe for hu man con sump tion.
