Article Synopsis
- * Results indicate no increase in plutonium levels in fish after major discharges from 2018-2020, but grayling had significantly higher Pu concentrations due to their diet of benthic invertebrates, while larger pike showed increasing Pu levels.
- * High concentrations of radiocesium and potassium were found in pike, attributed to biomagnification, leading to potential ecological risk assessments and a foundation for future research on radionuclides in freshwater ecosystems.
MOX-fuel production and spent nuclear fuel reprocessing started recently at the Mining-and-Chemical Combine (MCC, Zheleznogorsk, Russia) have caused an increase in controlled releases of plutonium to the Yenisei River. In this study, we analyzed time-dependent trends of plutonium (Pu and Pu) in biota and bottom sediments of the Yenisei during 2008-2019, to estimate comparatively the potential of abundant representatives of biota as bio-monitors of contamination of the Yenisei by plutonium. Gamma-emitting radionuclides ( K; Co; Cs; Eu; Am) were measured in environmental samples of the Yenisei as well.
