“…For example, the transfer factors (TF) for radiocesium in mushrooms were reported to be 2.6-21 in several culture tests (Muramatsu et al 1991 ;Ban-nai et al 1994 ). However, the radiocesium activity ratio in mushrooms relative to the soil in a fi eld study were rather low and the ratio was often <1 (Heinrich 1992 ).…”

High concentrations of radionuclide contamination of wild mushrooms occurred near the Fukushima Daiichi nuclear power plant and along the path of radioactive plumes. This is a serious problem for the forest ecosystem and commercial wild mushroom production. Radioactivity in wild mushrooms collected from low-level contamination forest areas throughout Japan was measured approximately 6 months after the accident. In general, the radioactivity in mushrooms did not exceed those in the neighboring forest litter. However, further accumulation of 137 Cs is expected in mushrooms; therefore, continuous monitoring is necessary even in low-contamination areas. We also found that residual 137 Cs radioactivity due to nuclear weapons tests, mainly in 1950s, besides fallout from the Fukushima nuclear accident still remained in soil and was accumulated by mushrooms.

Abstract. As the chemical behavior of radiocesium is expected to be almost identical to that of stable Cs, analyses of stable Cs and related stable elements should be useful to understand the long-term behavior of radiocesium and its equilibrium distribution in forest ecosystems. In this study, the concentrations of stable Cs and related alkali and alkaline earth elements in mushrooms, plants and soils were determined by inductively coupled plasma-mass spectrometry (ICP-MS) or inductively coupled plasma-atomic emission spectrometry (ICP-AES). Samples were collected in forests with different contamination levels in Japan. Germany, Finland, Italy, Ireland and Belarus. Vertical distributions in soils, and concentrations in mushrooms and plants were summarized for radiocesium and related stable elements. Relationship between radiocesium and stable Cs in mushrooms and plants, and transfer from soil to vegetation were also discussed. The results indicated that the ratio between radiocesium and stable Cs is useful for judging the equilibrium of deposited radiocesium in different parts of a forest ecosystem. The stable Cs analyses might be also useful to predict the long-term radiocesium contamination of mushrooms and plants.

“…With regard to S. granulatus, the effects of litter addition (36), the determination of mercury (37), radiocesium, and potassium (38), the amino acid composition (39), the genetic diversity, and interrelationships with other common European Suillus species (40) have been previously reported.…”

The organic acids and phenolics compositions of nine wild edible mushrooms species (Suillus bellini, Tricholomopsis rutilans, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Suillus luteus, and Suillus granulatus) were determined by HPLC-UV and HPLC-DAD, respectively. The antioxidant potential of these species was also assessed by using the DPPH • scavenging assay. The results showed that all of the species presented a profile composed of at least five organic acids: oxalic, citric, malic, quinic, and fumaric acids. In a general way, the pair of malic plus quinic acids were the major compounds. Only very small amounts of two phenolic compounds were found in some of the analyzed species: p-hydroxybenzoic acid (in A. rubescens, R. cyanoxantha, and T. equestre) and quercetin (in S. luteus and S. granulatus). All of the species exhibited a concentration-dependent scavenging ability against DPPH • . T. rutilans revealed the highest antioxidant capacity.
