Efficacy of Trophic Transfer of Radioactive and Stable Isotopes of Metals to Zoobenthos-Feeding Fish of the Yenisei River
Accumulation of radioactive and stable isotopes of metals in trophic chain of the Yenisei River leading to zoobenthivorous fish species, dace (Leuciscus leuciscus baicalensis) and grayling (Thymallus arcticus), have been investigated. Concentration factors (CF) of radionuclides and metals in trophic...
