[en] Highlights: • Sources of the 90Sr inflow into the salt lakes of the Crimea were identified. • Solubility of 90Sr is largely dependent on the level of salinity of water of the lakes. • Main content of 90Sr was in water column of the salt lakes of the Crimea. • Redistribution of 90Sr between the hydrobionts and bottom sediments was insignificant. • Absorbed doses received by hydrophytes from ionizing radiation of 90Sr had no noticeable impact on hydrobionts. - Abstract: At the first time for the period after the Chernobyl NPP accident the nature of the redistribution of the 90Sr concentrations in components of the ecosystems of the salt lakes of the Crimea were identified and described. Concentration of 90Sr in water of the salt lakes depends on the sources of the inflow this radionuclide into aquatic ecosystems and salinity level of lakes water. Until April 2014 the flow of the Dnieper river water through the Northern-Crimean canal was more important factor of contamination of salt lakes of the Crimea by 90Sr, than atmospheric fallout of this radionuclide after the Chernobyl NPP accident. Concentrations of 90Sr in water of the salt lakes of the Crimea exceeded 2.4–156.5 times its concentrations in their bottom sediments. The 90Sr dose commitments to hydrophytes, which were sampled from the salt lakes of the Crimea have not reached values which could impact them during entire the after-accident period.
