The current state of the hydroecological problems of the inland water bodies of Ukraine has been elucidated. Results of application of the European approaches to solution of the main rivers' basins (the Dnieper, the Danube etc.) hydroecological problems, based on the actual methods of the aquatic ecosystems assessment and determination of their ecological status have been presented. Information is given on investigation within the frames of some international programs realization (TACIS, UNDP GEF etc.). Conclusion is made about tendency to “ecologization” of the hydrobiological studies.

The study of water bodies of the Kiliya Delta of the Danube River, including the Anankin, Gniloy, Limba, Maly Lazarkin, Delyukov, and Potapov bays and lakes, has shown that the qualitative and quantitative characteristics of phytophilous complexes of aquatic invertebrates depend on the type of a water body and on the intensity of development of macrophytes.

anthropic influence
monitoring
A total of 56 taxa of zooplankton, 108 taxa of zoobenthos, and 26 species of fishes was found in the middle reaches of the Lena River. Contamination of the river resulted in the decrease in biological diversity, and also in changes in the structure of zoocenoses. Anomalies were registered in the structure of the organs of fishes. In addition, they were characterized by a rather high content of heavy metals. Results of the study of hydrobionts suggest that the middle reaches of the Lena River are assigned to slightly contaminated water courses.

Results of experimental investigations on the influence of ultraviolet radiation on the peculiarities of lipid peroxidation in algae of various taxonomic groups, including Chlorophyta (Scenedesmus obtusus Meyen and Desmodesmus brasiliensis Bohl.), Cyanophyta (Anabaena cylindrica Lemm. and Phormidium autumnale f. uncinata (Ag.) Kondrat.), Euglenophyta (Euglena gracilis Klebs), and Bacillariophyta (Navicula atomus (Näg.) Grun.), are given in the paper. It has been found that the studied species differed in the peculiarities of free radical oxidation of polyunsaturated carbonic acids involved in the composition of lipid structures of algae cells.

Resistance rate of three mobile algae species of the genus Chlamydomonas (Chlorophyta) - Ch. reinhardtii, Ch. aculeata, Ch. pitschmannii to the presence of the most toxic six-valency chromium (taking K2Cr2O7 as an example) was estimated using the method combination (microscopic analysis, spectrophotometry and laser-Doppler spectrometry). Protective mechanisms of the algae cells providing their surviving under the unfavorable effect of the chemical factors of the aquatic environment have been discussed. Among protective responses of the studied algae the following should be noted: appearance of the big toxic-resistant cells in suspension, rise of velocity and energy inputs to the cells movement, as well as formation of the oil drops in the cells.

The test responses of Lepidium sativum L. to the toxic influence of the water of small rivers of the town of Chernivtsi in the places of sewage release were compared and analyzed. The following indices were taken into account: energy of seed germination, germinating capacity, and the length of the main root. The most dangerous sources of surface waters contamination were revealed.

Results of parasitological studies of more than 3000 specimens of gammarids from the water bodies and streams of the north-east Poland are presented. Microsporidians (Pleistophora muelleri, Nosema pontogammari) and gregarines (Cephaloidophora sp., Uradiophora ramosa) were registered in four (Gammarus fossarum, G. pulex, Obesogammarus crassus, Pontogammarus robustoides) of 12 investigated species of gammarids, which belong to the native Boreal, Ponto-Caspian and North American faunistic groups. Infestation rate did not exceed 3%. All indicated species of microparasites were regustered in Poland for the first time. Transition of parasites of the Ponto-Caspian hosts to the hosts of native fauna was not registered.

Paper deals with data on metals migration (Mn, Al, Cu, Zn, Pb, Cr) within the system “bottom sediments − water” depending on the oxygen regime of the water bodies. Oxygen saturation rate in the surface layer of the Kaniv reservoir in the investigation period amounted to 48.7−84.7%, and in the near-bottom layer oxygen deficit was observed (0.4−0.9 mg/dm3). In the Telbin Lake the surface layer was over-saturated by oxygen (119−206%), whereas in the near-bottom layer oxygen content during some months was at zero level. This fact caused intensive manganese migration from the bottom sediments. Its concentration in the near-bottom layer increased about 25 times in the Kaniv reservoir and 50−60 times in the Telbin Lake. Migration of other considered metals was incommensurably less. Data on relation of the suspended and dissolved metals forms, as well as their free (hydrated) ions and complex compounds with dissolved organic matters (DOM) are considered. Chemical nature of complexes and peculiarities of the metals fixation by different DOM fractions in the studied water bodies are discussed
