Results of radioecological investigations of aquatic ecosystems carried out for 25 years after the accident at the Chernobyl NPS are given in the paper. Dynamics of radionuclide content in abiotic and biotic components of water bodies of the Chernobyl exclusion zone and of the Dnieper River and its reservoirs, and also the peculiarities of the formation of irradiation doses on hydrobionts and a wide spectrum of radiation effects in biosystems of different levels of organization, are analyzed.

Samples were taken at more than 80 stations located within the basin of the Dnieper River. The distribution of mollusks of the genus Unio, the frequency of their occurrence, and the density of their populations were investigated along with the study of hydrological and hydrochemical characteristics of sampling stations. The ecological spectra of mollusks were determined. The peculiarities of the distribution and ecology of these animals were compared with those given in literature.

The process of sulfate reduction in bottom sediments was studied in the Volga reservoirs and in Lake Nero. It has been found that in the places of industrial and household sewage release the intensity of this process increased. The maximal rate of sulfate reduction (143.6 mg S/(kg·day) and the maximal numbers of sulfate reducing bacteria (10 million cells/g) were observed in the Sheksna stretch of the Rybinsk Reservoir near the town of Cherepovets.

Total content of lipids and their fatty acids composition in the widespread seaweeds of the Odessa Bay of the Black Sea: Chlorophyta − Enteromorpha intestinalis (Nees) Link, Chaetomorpha aerea (Dillw.) Kütz., Bryopsis plumosa (Huds.) C. Ag., Cladophora vagabunda (L.) Hoek; Rhodophyta − Porphyra leucostica Thur., Polysiphonia elongate (Huds.) Spreng., Ceramium siliquosum var. elegans (Roth) G. Furmari; Phaeophyta − Scytosiphon simplicissimus (Clemente) Cremades and Punctaria latifolia Grev. was investigated. Seaweeds of the department Chlorophyta were characterized by maximal content of lipids and polyunsaturated fatty acids. In the seaweeds' lipids prevailed unsaturated fatty acids: oleic, linoleic and linolenic.

Prolonged effect of allochthonous nitrogen on blood of the two-year-old carps and grass carps has been studied. Increase of ammonia, nitrites and total protein content, as well as hemoglobin and methemoglobin content in blood was noted. Changes of fraction composition of proteins in the blood plasma were stated.

sensitivity
Infusorian Stylonychia mytilus shows elevated sensitivity to low (0.00005−0.001 mg/l) and high (from 0.50 mg/l) concentration of the amine-contained flotation reagent PA-14. Relative resistance to mediate (0.01−0.40 mg/l) concentration is explained by adaptation to toxic natural amines, which are contained in the surface water bodies in the same limits. Obtained results can serve as a basis to review established MPC (maximal permissible concentration) of PA-14 (0.003 mg/l) and methodology of MPC calculation on the whole.

On the base of literature date and author's own researches effects of heavy metals on chemoreception and behavior of crustaceans are reviewed. Elevated concentration of metals, as compared with background, was shown to disturb chemoreception and connected with it behavior of crustaceans. Modifications of the crustaceans' behavior occur under concentration and expositions significantly lower than LC50 in acute experiments.

Content of glycogen in mussels Mytilus galloprovincialis in different biotopes and sites with different water exchange rate and anthropogenic load has been studied. Glycogen content in the mussels' body was shown to characterize their state in connection with habitat peculiarities and serve as indicator of environmental conditions.

Impact of the crude oil and diesel fuel on activity of succinate dehydrogenase and cytochrome-c-oxidase in the gills and liver of fish has been studied. Activity of these enzymes was shown to increase under the effect of diesel fuel, and decrease under the effect of the crude oil. Conclusion has been made that row oil is more toxic for the energy metabolism of fishes.
