137Cs activity concentration in mushrooms from the Bobrůvka river valley

Abstract

In the 2017-2018 mushrooming seasons at the (Bohemian-Moravian Highlands near Dolní­ Roží­nka) a total of 505 mushrooms belonging to 9 species were collected, and analyzed by gamma spectrometry for 137Cs activity. The maximum 137Cs activity of 575 Bq.kg-1 was detected in Boletus edulis species, what in native state, is just below the allowed limit. In contrast, in mushroom Imleria badia, which is reported to be associated with the highest cumulative capability from all fungi species, detected activity level was only 316 Bq. kg-1. However, differences in mean contamination values were not significant due to high variability. It was shown, that activity concentration is not dependent on the weight (size) of Imleria badia. Our results also confirmed generally well known lower 137Cs activity in the Russula species representatives belonging to the group of gills or lamella bearing mushrooms.

“…Currently, despite more than 36 years since the Chornobyl disaster, radioactive contamination of macromycetes attracts the attention of researchers in Europe: Italy [1], Czech Republic [2], Slovakia [3], Poland [4,5], Bulgaria [6], Turkey [7]. After the accident at the Fukushima Nuclear Power Plant, the radioecology of macromycetes obtained a new development in Asia -Japan [8,9] and China [10].…”
