The paper deals with content of certain lipid groups (triacylglycerols (TAG), diacylglycerols (DAG), non-etherified fatty acids (NEFA) and phospholipids (PhL)) in body of the freshwater mollusks Lymnaea stagnalis (Linnaeus, 1758), and Unio pictorum (Linnaeus, 1758), which differ in anatomical and morphological structure, ecological features, nutrition spectra and motor activity. The lipid composition of the mollusks is species specific and significantly varies in the considered organs. The lipid content in U. pictorum organs differed in males and females.

Changes of cortisol, triiodothyronine, and thyroxine content in the blood plasma of perch, ruff, rudd and bleak under the impact of agricultural runoff from the adjacent territories to the water bodies were studied. Under the long-term exposure to the contaminated water, the weight and size of fish their growth rates specimens significantly decreased. The hormonal responses to the polluted waters impact are species-specific and partly depend on the ecological features of the species. Under the chronic impact of the polluted water, the cortisol content in blood plasma decreases and triiodothyronine content increases as compared to the control. The fishes occurring in the surface water layers create the thyroxine reserve in blood, and fishes which prefer the near-bottom layers use it to increase the triiodothyronine content. After treatment of the fields close to the reservoir with pesticides, the ruff and rudd develop the active stress reaction, the cortisol and thyroxine content in blood significantly increases. According to the considered indicators, the bleak is the most resistant to agricultural runoffs or possesses the ability to avoid toxic water pollution.

The spread of crustaceans of the order Cumacea in the Dnieper reservoirs is analyzed in the paper. It is thought that these crustaceans could get into the newly formed reservoirs along with the introduced Gammaridae, Mysidae, and Mollusca. In all reservoirs of the Dnieper cascade, except for the Kyiv Reservoir, where they have not been found till now, 4-5 species of Cumacea have been registered. Pterocuma pectinata (Sow.) dominates in terms of the quantitative indices of its development. During the period of investigations, the numbers and biomass of Cumacea accounted for respectively 25-131 specimens/m2 and 0.06-0.13 g/m2. The highest quantitative indices of Cumacea development were observed at the depths of 2-7 m on sands and silted sands.

The study is based on long-term observations (1998-2021) over the species richness and cenotic activity of macrophytes of floodplain water bodies of the Chornobyl exclusion zone. During this period, the species composition of macrophytes of the studied water bodies remained almost unchanged. The lists of species found in 1998 differ from those registered in 2021 only by three species, including Nymphaea alba, Trapa natans (registered only since 2007), and Utricularia minor (found only in 1998, whereas in subsequent years was not observed at all). In the studied water bodies, macrophytes are not diverse in their species composition; their cenotic structure is simple, whereas overgrowing intensity of water surface is high. The presence of rare species of the boreal complex, including primarily Hottonia palustris, Potamogeton acutifolius, and Callitriche cophocarpa, makes these water bodies objects of protection and research. In 1998, a common feature of the vegetation cover of all studied floodplain water bodies was a predominance of macrophyte communities, in which the species of river and lake ecosystems, as well as indicator species of increased water logging processes, were registered. At the present time, natural structure of macrophyte communities of floodplain water bodies of the Prypyat River, which was deteriorated as a result of the construction of flood-protection hydraulic structures, is gradually recovered. The peculiarities of the distribution of macrophytes at the present time are indicative of the improvement of water exchange in floodplain water bodies. The chronic ionizing radiation influencing the biota of the studied water bodies for more than 30 years did not result in significant changes in the floristic and cenotic composition of macrophytes. Certain changes are conditioned by changes in hydrological and hydrochemical regime of the floodplain of the Prypyat River.

The readaptation of the crucian carp after some generations of successful adaptation in the reservoir contaminated by inorganic nitrogen compounds and its return to favorable environmental conditions was investigated. After the 3-month adaptation to standard conditions, all considered physiological parameters (organ indices and Fulton fatness) reached the control values. At the same time, biochemical parameters did not return to the initial physiological state. According to the hormones (cortisol, T3 and T4) and glucose content in blood plasma, it can be stated that the experimental specimens had the energy-saving metabolism. The experimental specimens developed somewhat other way of the excess ammonium nitrogen excretion from the organism. Thus, content of protein as the basis of ammonia transport, in the blood plasma was lower than in control. Over the readaptation period, the experimental specimens had the increased hemoglobin content in blood. Thus, within three months complete readaptation of carp did not take place, the biochemical state was the most revealing.

The significance of preventing an adverse effect of various detergents and sanitizers used for the treatment (sanitation) of dairy farm equipment while maintaining its proper sanitary conditions on water bodies is underlined in the paper. Probable release into the environment of the tested sanitizing agents, including alkaline (Desmol, San alkaline, and Basix) and acidic (CircoSuper SFM, Tigma-K, and Biolight ST-2) products, from the farm per 1000 cows is predicted. Water environment toxicity at different concentrations of these sanitizers was assessed by the method of bioassay in terms of the survival rate of various hydrobionts, including Tetrahymena pyriformis, Daphnia magna, Lymnaea stagnalis, Dendrocoelum lacteum, and Poecilia reticulata. The zone of toxic effect of the studied agents, which forms the basis of the ecological passport of substances based on their influence on hydrobionts (LC0, LC50, and LC100) was determined.

Trace metal concentrations with regard to certain life stages and sex of mysid species, Mesopodopsis orientalis, from the Cochin estuary were studied during monsoon and pre-monsoon seasons. Spatially varying heterogeneous patterns of trace metal loads were apparent within the mature males, immature males, spent females, brooding females, immature females and juveniles of M. orientalis for the region. The concentration ranges of trace metals like Fe, Mn, Zn, Pb, Cu, Cd, Ni, Cr and Co in M. orientalis were: 590.5 to 1554.9 mg/kg, 4.1 to 15.1 mg/kg, 42.0 to 126.5 mg/kg, 2.5 to 17.0 mg/kg, 12.8 to 61.9 mg/kg, 0.2 to 2.3 mg/kg, 7.6 to 25.5 mg/kg, 8.8 to 33.4 mg/kg and 0.2 to 2.2 mg/kg, respectively. Higher metal concentrations were noted for the life stages of M. orientalis during the monsoon season than in the pre-monsoon season. Mature males, immature males, spent females, brooding females, immature females and juveniles of M. orientalis showed large variability in bioaccumulation for specific metals probably associated with distinct physiological processes. Juveniles and immature stages of M. orientalis showed higher metal concentrations than adult organisms. High metal bioaccumulation and its spatial and seasonal variability with regard to animal life stages and sex suggest the importance of M. orientalis as a biomonitor for tracing metal contamination in estuarine environments.

The structure of the communities of epiphyton algae was studied in the water bodies of the «Oleksandriya» State Dendrological Park (the town of Bila Tserkva, Ukraine). It has been found that the ponds located in the Western ravine were characterized by an essentially higher level of complex anthropogenic contamination (by inorganic compounds of nitrogen and phosphorus, chloride, sulfate, and organic substances) compared to the water bodies of the Middle and Eastern ravines. Respectively, the types of the communities of epiphyton algae (syntaxa) distinguished in the water bodies differing in the level of contamination also differed in the composition, number, and ecological characteristics of diagnostic taxa, in the species richness of epiphyton algae on the whole, in the average number of species in individual communities, in their taxonomic structure, in the quantitative indices of algae development, and in the complex of dominant species. It has been found that the communities of epiphyton algae registered in the ponds of the Western ravine belong to the association Gomphonemo parvuli-Nitzschietum paleae, whereas the communities of epiphyton occurring in the Middle and Eastern ravines - to the association Cocconeo placentulae-Naviculetum tripunctatae. The obtained data on the communities of epiphyton algae can be used for synbioindication of the state of water bodies differing in the level of contamination in performing ecological monitoring.

The communities of benthos invertebrates occurring in various biotopes of the water bodies, watercourses, and coastal zone of the Kiliya delta of the Danube River were distinguished based on the similarity of their species composition. It has been found that mainly water salinity is responsible for the formation of their physiognomy and hierarchic organization in the Kiliya delta of the Danube River, whereas the types of bottom sediments and the types of water bodies are responsible for the formation of their components. The levels of hierarchic organization of benthos communities are as follows: the lowest level is formed by primary mosaic communities occurring in various water bodies and on various types of bottom sediments, the next level is formed by the united communities distributed on various types of bottom sediments in fresh or brackish water bodies, whereas the highest level is formed by the communities of the Kiliya branch and the Danube River delta on the whole. It has been shown that the discreteness and continuality of benthos communities in the Kiliya delta of the Danube River are formed due to the development of both fresh and brackish species.
