Радиоактивность и радиоактивные элементы в среде обитания человека : материалы VI Международной конференции, 20-24 сентября 2021 г Т. 2. С. 50-54Abstract: The features of different stages of ontogenesis of the background amphibian species, the Moor frog Rana arvalis (Ranidae, Amphibia), in the area influenced by the Siberian chemical combine (SCC, Tomsk Region) were studied. In 1993–1994, multiple embryogenesis disorders and pathology of larvae and juvenile individuals, accumulation of lanthanides and actinides by organisms, were found. The results indicate an ecological disadvantage in the areas around nuclear fuel cycle enterprises. Over the next 20 years, some of SCC's manufacturing facilities were closed and repurposed. In 2014–2015, in repeated studies, radioisotopes and heavy metals were not detected in the Moor frog R. arvalis embryos. The results indicate the usefulness of amphibians as bioindicators of aerial global and radioactive fallouts and accidental releases, and during long-term radioecological monitoring. Bioindication of technogenic impacts at the embryonic and histological levels should be considered the most promising approach.
