It was determined that the higher aquatic plants and fish from the rwater-bodies of the Chernobyl exclusion zone in conditions of prolonged exposure to ionizing radiation show increased sensitivity to additional acute irradiation by sublethal doses compared to hydrobionts from ponds with background levels of radionuclide contamination. In particular, the seed sprouts of common reed from polluted waters are characterized by low rates of germination and growth rates, which are significantly reduced with additional acute irradiation compared to the control. Fish from contaminated waters, which are characterized by altered WBC and a wide range of morphological abnormality of red blood cells, respond to additional acute irradiation significantly higher levels of pathogenesis of peripheral blood formed elements. The foregoing indicates a lack of adaptive radiation processes studied indicators of aquatic organisms from living in a gradient of radionuclide contamination of water bodies of the Chernobyl exclusion zone. For the cooling ponds of Chernobyl and Khmelnitsky NPP was investigated the process of change of the dominant species in the contour konsortivnye groups. It was found that, together with the effects of naturalization of Dreicena Bug k phenomena of "kontyrization" in the ecosystem is almost not observed. There were obtained tchangesin the range of phytoplankton species, namely, the proportion of diatoms and reduce - the blue-green, but the latter passed the dominance by biomass.
