THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 802:149829. [PMID: 34464794 DOI: 10.1016/j.scitotenv.2021.149829] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 08/17/2021] [Accepted: 08/18/2021] [Indexed: 06/13/2023]
Abstract
A considerable amount of data has been published on the accumulation of radiocaesium (134Cs and particularly, 137Cs) in wild fungi since the first anthropogenically influenced releases into the environment due to nuclear weapon testing, usage and subsequently from major accidents at nuclear power plants in Chernobyl (1986) and Fukushima (2011). Wild fungi are particularly susceptible to accumulation of radiocaesium and contamination persists for decades after pollution events. Macromycetes (fruiting bodies, popularly called mushrooms) of the edible fungal species are an important part of the human and forest animal food-webs in many global locations. This review discusses published occurrences of 134Cs and 137Cs in twenty four species of Tricholoma mushrooms sourced from the Northern Hemisphere over the last five decades, but also includes some recent data from Italy and Poland. Tricholoma are an ectomycorrhizal species and the interval for contamination to permeate to lower soils layers which host their mycelial networks, results in a delayed manifestation of radioactivity. Available data from Poland, over similar periods, may suggest species selective differences in accumulation, with some fruiting bodies, e.g. T. portentosum, showing lower activity levels relative to others, e.g. T. equestre. Species like T. album, T. sulphurescens and T. terreum also show higher accumulation of radiocaesium, but reported observations are few. The uneven spatial distribution of the data combined with a limited number of observations make it difficult to decipher any temporal contamination patterns from the observations in Polish regions. When data from other European sites is included, a similar variability of 137Cs activity is apparent but the more recent Ukrainian data appears to show relatively lower activities. 40K activity in mushrooms which is associated with essential potassium, remains relatively constant. Further monitoring of 137Cs activity in wild mushrooms would help to consolidate these observations.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:10.1007/s11356-021-12433-8. [PMID: 33625702 PMCID: PMC8241671 DOI: 10.1007/s11356-021-12433-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 01/07/2021] [Indexed: 06/12/2023]
Abstract
B. edulis, collected from 33 forested or woodland sites across Poland over 25 years since 1995, were analysed for radiocaesium. The results (137Cs activity range: 25 to 10,000 Bq kg-1 dry weight) provide a good indication of artificial radioactivity in this food material. The relatively higher levels detected in the earlier years, mostly in easterly location, is consistent with depositions from the projected Chernobyl incident (1986) fallout plumes. Nevertheless, the 137Cs concentrations during 1995-2010 were, on average, higher than those reported by other studies for Polish B. edulis over the period 1986-1994. The data concurs with the general hypothesis and observations that deposited 137Cs permeates slowly over time to deeper soil horizons which host the mycelial networks. This delay in availability shows that (apart from hotspots) higher contamination of fruiting bodies occurred around 10 to 20 years after the incident. Local consumers and recreational mushroomers were undoubtedly exposed, although reported 137Cs concentrations suggest that serious breaches of regulated levels were uncommon.

Abstract
Studies have been conducted in some southern Iraqi governorates to measure the radioactive contamination in the soil and have revealed that these areas are contaminated with radioactive materials. In these test sites, where many military operations have been conducted and that may have been affected by the Chernobyl accident, pollution and its impact on the truffle crop have been examined. Truffles are fungi that grow in the ground and can be contaminated by radiation from polluted soil. Uranium, thorium, potassium, and cesium activities were analyzed in truffles collected from the desert of Samawah governorate in the southern part of Iraq, and the results were compared with global values. The radionuclide activities were measured with a high-purity germanium detector. The average activities of 238U, 232Th, 40K, and 137Cs were 3.9500, 2.5300, 260.36, and 1.7800 Bq kg-1 dry biomass, respectively. These results indicate that radionuclide activities are low and that desert truffles are suitable for human consumption.

Abstract
The activity concentrations of (137)Cs and (40)K in mushrooms of the genus Cantharellus (Cantharellus cibarius, Cantharellus tubaeformis, and Cantharellus minor) collected across Poland from 1997 to 2013 and in Yunnan province of China in 2013 were determined using gamma spectrometry with an HPGe detector, respectively. Activity concentrations of (137)Cs in C. cibarius from the places in Poland varied from 64 ± 3 to 1600 ± 47 Bq kg(-1) db in 1997-2004 and 4.2 ± 1.2 to 1400 ± 15 Bq kg(-1) db in 2006-2013. In the Chinese Cantharellus mushrooms, the activity level of (137)Cs was very low, i.e., at a range <1.2 to 1.2 ± 0.6 Bq kg(-1) dry biomass. The natural radionuclide (40)K was at similar activity level in C. cibarius collected across Poland and in China, and fluctuations in levels of (40)K over the years and locations in Poland were small. In C. cibarius from diverse sites in Poland, content of (137)Cs highly fluctuated in 1998-2013 but no clear downward trend was visible (Fig. 1). Published activity levels of (137)Cs in fruitbodies of Cantharellus such Cantharellus californicus, Cantharellus cascadensis, C. cibarius, Cantharellus cinnabarius, Cantharellus formosus, Cantharellus iuteocomus, Cantharellus lutescens, Cantharellus minor, Cantharellus pallens [current name C. cibarius], Cantharellus subalbidus, Cantharellus subpruinosus, and C. tubaeformis collected worldwide were compared. In the Polish cuisine, mushrooms of the genus Cantharellus are blanched before frying or pickling, and this kind of treatment, and additionally also pickling, both very efficiently remove alkali elements (and radioactivity from (134/137)Cs) from flesh of the species.

Abstract
Mushrooms and soils collected from pine forests in Izmir, Turkey were measured for radiocesium and stable Cs in 2002. The ranges of (137)Cs and stable Cs concentrations in mushrooms were 9.84+/-1.67 to 401+/-3.85Bqkg(-1) dry weight and 0.040+/-0.004 to 11.3+/-1.09mgkg(-1) dry weight, respectively. The concentrations of (137)Cs and stable Cs in soils were 0.29+/-0.18 to 161+/-1.12Bqkg(-1) dry weight and 0.14+/-0.004 to 1.44+/-0.045mgkg(-1) dry weight, respectively. Even though different species were included, the concentration ratios of (137)Cs to stable Cs were fairly constant for samples collected at the same forest site, and were in the same order of magnitude as the (137)Cs to stable Cs ratios for the organic soil layers. The soil-to-mushroom transfer factors of (137)Cs and stable Cs were in the range of 0.19-3.15 and 0.17-12.3, respectively. The transfer factors of (137)Cs were significantly correlated to those of stable Cs.

Abstract
Concentrations of some radionuclides, including 137Cs, in desert truffles in Kuwait were studied and compared with similar samples from other countries in the Middle East, namely Iran, Egypt, and Tunisia. In addition, sand samples from Kuwait were assayed to calculate the transfer factor of the radionuclides under consideration. The measured concentrations of 40K, 226Ra, and 137Cs show that 137Cs is much higher in Egyptian samples, whereas 40K is much lower in samples from Tunisia. The average effective dose equivalent calculated for the Kuwaiti population according to their diet habits was found to be in the range 0.14-0.23 microSv/a. The results are compared with values from other countries.
