“…The radiation dose on the organisms, first by the radionuclides contained in water and bottom sediments, is an important integral criterion of the radioactive pollution effect on the aquatic biota [80,84,85]. At this, the organisms are able to concentrate the radionuclides in organs and tissues, which can result in a notable increase in the dose load owing to internal irradiation [86][87][88]. At the same time, average levels of internal irradiation of aquatic organisms from the radionuclides near nuclear power plants are much lower than irradiation from radionuclides occurring in the environment [79,80].…”

The inheritance of historic human-induced disruption and the fierceness of its impact change aquatic ecosystems. This work reviews some of the main stressors on freshwater ecosystems, focusing on their effects, threats, risks, protection, conservation, and management elements. An overview is provided on the water protection linked to freshwater stressors: solar ultraviolet radiation, thermal pollution, nanoparticles, radioactive pollution, salinization, nutrients, sedimentation, drought, extreme floods, fragmentation, pesticides, war and terrorism, algal blooms, invasive aquatic plants, riparian vegetation, and invasive aquatic fish. Altogether, these stressors build an exceptionally composite background of stressors that are continuously changing freshwater ecosystems and diminishing or even destroying their capability to create and maintain ongoing natural healthy products and essential services to humans. Environmental and human civilization sustainability cannot exist without the proper management of freshwater ecosystems all over the planet; this specific management is impossible if the widespread studied stressors are not deeply understood structurally and functionally. Without considering each of these stressors and their synergisms, the Earth’s freshwater is doomed in terms of both quantitative and qualitative aspects.

The paper deals with analysis of hematological parameters of the common rudd (<i>Scardinius erythrophthalmus </i>L.) and Prussian carp (<i>Carassius gibelio</i> Bloch) from the most radionuclide-contaminated water bodies of the Chernobyl Exclusion Zone. Data on absolute and relative leukocyte composition and morphological disorders of erythrocytes in peripheral blood were obtained. The leukocyte fraction of both fish species similarly responded to the absorbed dose rate. In the doses' range of 5.1-54.1 μGy/h, reactive changes of the compensatory nature were recorded with increase of the leukocytes content at the expense of lymphocyte and granulocyte fractions. Under the higher doses (up to 84.5 μGy/h), hematopoiesis was damaged with sharp decrease of the leukocytes' content and significant changes in leukograms, which was also confirmed by the hematological indices' values. The morphological disorders in erythrocytes increased along with absorbed dose rate.

The structural indices of the communities of benthic and phytophilous invertebrates were studied in water bodies differing in the levels of external radiation dose rate within the Chornobyl exclusion zone. The macrofauna of invertebrates of all studied water bodies was characterized by low species richness, numbers, and biomass. The obtained results suggest that the benthic and phytophilous invertebrate fauna of the cooling pond of the Chornobyl Nuclear Power Plant differs in its structure from the fauna of other water bodies of the Chornobyl exclusion zone more significantly than these water bodies differ from each other in terms of dose load levels on the biota. We consider the main reason for these differences to be the succession processes in the ecosystem caused by the transformation of the cooling pond of the Chornobyl Nuclear Power Plant. There is no reason to claim that the influence of external ionizing radiation determines the change in the structural indices of the communities of benthic and phytophilous invertebrates in water bodies of the Chornobyl exclusion zone.
