Data on the current content of major dose-forming radionuclides (90Sr, 137Cs and 241Am) in abiotic and biotic components of aquatic ecosystems were obtained. A retrospective analysis of the dose rate was evaluated and the current absorbed dose rate for higher aquatic plants of different ecological groups due to external and internal radiation sources was calculated. Preliminary data on cytogenetic and hematological effects of long-term effects of ionizing radiation on aquatic biota have been obtained. Disturbances of the axial skeleton of young fish were determined, as well as meristic, plastic and anatomical and morphological parameters of fish, benthic invertebrates and higher aquatic plants and their reproductive parameters were studied.
