“…The health risk associated with the consumption of PTE contaminated A. bisporus by the consumers of Uttarakhand State, India was computed using the Target Hazard Quotient (THQ) approach. By using THQ, a health risk index (HRI) is developed, which is used to assess the occurrence of health hazards [ 31 , 32 , 33 ]. An HRI value above 1 indicates a potential health risk in consuming the contaminated mushroom [ 34 ].…”

This study presents a spatial assessment of eight potentially toxic elements (PTE: Cd, Cr, Cu, Fe, Pb, Ni, Mn, and Zn) in white button (Agaricus bisporus J.E. Lange) mushroom samples collected from the local vegetable markets of Uttarakhand State, India. Fresh A. bisporus samples were collected from thirteen districts and fifteen sampling locations (M1-M15) and analyzed for the concentration of these PTE using atomic absorption spectroscopy (AAS). The results revealed that A. bisporus contained all eight selected PTE in all sampling locations. Based on the inverse distance weighted (IDW) interpolation, principal component (PC), and hierarchical cluster (HC) analyses, the areas with a plane geographical distribution showed the highest PTE concentrations in the A. bisporus samples as compared to those in hilly areas. Overall, the decreasing order of PTE concentration in A. bisporus was recognized as Fe > Zn > Mn > Cr > Cu > Ni > Cd > Pb. The Kruskal–Wallis ANOVA tests displayed a highly significant (p < 0.05) difference among the sampling locations. However, the concentration of PTE was below permissible limits, indicating no potential hazard in consuming the A. bisporus. Similarly, the health risk assessment studies using the target hazard quotient (THQ) also showed no significant health risk associated with the consumption of A. bisporus being sold in the local mushroom markets of Uttarakhand, India. This study is the first report on state-level monitoring of PTE in A. bisporus mushrooms, which provides crucial information regarding the monitoring and occurrence of potentially toxic metallic elements.

“…Edible species that grow in the wild were considered as a potentially significant source of human dietary exposure to radiocaesium ( 134/ 137 Cs) from the atmospheric fallout of radioactivity from nuclear weapon testing in the atmosphere and nuclear power plant accidents (Daillant et al 2013;Kiefer et al 1965;Rantavaara 2003). In particular, the incident at the Chernobyl nuclear power plant in 1986 led to 137 Cs contamination of wild mushrooms in surrounding European regions (Betti et al 2017;Daillant et al 2013;Tucaković et al 2018). Similarly, the incident at the Fukushima-Daichi nuclear power plant in 2011 caused 137 Cs contamination of locally foraged mushrooms (Cui et al 2020), without showing any noticeable effect on the wild species collected in continental Asia and Europe (Falandysz et al 2018;Prand-Stritzko and Steinhauser 2018).…”

This study aimed to get an insight into the effects of household processing on the leaching behaviour of 137Cs and 40K from fresh, frozen and dried Boletus edulis (King Bolete) mushrooms. Three processes were investigated—blanching, blanching and pickling, and drying followed by grinding and soaking. The activity concentrations of 137Cs and 40K in the fresh unprocessed mushrooms were 270 Bq kg−1 dry biomass (27 Bq kg−1 whole weight) and 590 Bq kg−1 db (59 Bq kg−1 ww), respectively. Blanching of fresh mushrooms decreased 137Cs activity by 55%, and 40K activity by 34%, and blanching of deep-frozen mushrooms caused a reduction of 52% and 44% (db) (equivalent to whole weight reductions of 37% and 8.5%, and 67% and 22%, respectively). Blanching and pickling of fresh mushrooms decreased 137Cs activity by 83% and 40K activity by 87%, while blanching deep-frozen mushrooms resulted in decreases of 88% and 80% (db) (whole weight decreases of 77% and 81%, and by ~ 84% and 72%, respectively). This study confirms earlier reports that blanching of fresh or frozen mushrooms alone is not as efficient at removing 137Cs as blanching followed by pickling. The study also shows that the initial rate of fruiting body disintegration and pre-preparation (comparing fresh, deep-frozen, or dried and ground) can have an impact on the leaching rate of the water soluble fraction of metallic elements.

“…As an example of an organic food matrix, mushrooms were chosen. They are known to highly accumulate both 134,137 Cs , and Ag. ,, Shiitake mushrooms (Lenitula edodes) were grown on wood shavings incubated with Shiitake mycelium. The substrate (500 g) was homogeneously contaminated with 900 Bq 108m Ag and 100 kBq 137 Cs.…”

Separation of Ultratraces of Radiosilver from Radiocesium for Environmental Nuclear Forensics

et al. 2020

The presence of environmental radiosilver and the investigation of the 108m Ag/ 110m Ag isotopic ratio in the aftermath of a nuclear power plant accident provide valuable information on the condition of the control rods of pressurized water reactors. However, the detection of minute amounts of the γemitting radiosilver isotopes is often thwarted by the presence of concomitant and dominating γ emitters, primarily 137 Cs, which results in increased detection limits in the γ spectra. We developed a rapid and robust separation protocol for trace silver extraction in the presence of overwhelming activities of 137 Cs via the autodepostion of silver on a copper plate. This method achieved a quantitative removal of interfering 137 Cs in the deposition product and proved to be very efficient (yields >70% for aqueous samples), rapid (results within 4 h), and robust with respect to varying salinities and composition of the water samples. The autodeposition approach is also applicable for organic samples after acidassisted microwave digestion. By applying the established sequential extraction protocols for soil, the fate of freshly deposited radiosilver and radiocesium in soil was investigated. Silver showed a high affinity to the soil with a pronounced (>90%) accumulation in the residual fraction after the sequential extraction, whereas radiocesium exhibited higher mobility, allowing for the extraction of major fractions in the first extraction steps. The composition of the aqueous contamination matrix (CaCl 2 or Ca(NO 3 ) 2 ) had a significant influence on the binding properties of cesium on soil.
