Water bodies differing in their origin were classified in terms of phytoplankton diversity. The following indices were taken into account: phytoplankton species and taxonomic (at the level of orders and genera) diversity, the Sorensen coefficient of community, frequency of occurrence, and the Shannon index.

A total of 287 species of algae represented by 309 infraspecific taxa, including those containing nomenclatural types of species, of nine divisions was found in the fouling of solid inorganic substrata in the cooling pond of the Chernobyl Nuclear Power Station (NPS) as a result of long-term investigations. Bacillariophyta, Cyanophyta, and Chlorophyta were highly diverse in their species composition. In the section of the cooling pond subjected to considerable heating, the number of periphyton algae species was 1.5 times higher than that registered in the section with the minimum heating. A total of 255 indicator species was found in phytoperiphyton of the cooling pond of the Chernobyl NPS. Facultative thermophilic species prevailed in the section of the cooling pond subjected to considerable heating. The average values of saprobic index ranged from 1.8 to 2.7.

The introduction of the European Water Framework Directive (WFD) in Ukraine is under discussion during few years and that has led to an increased interest in such approach. This article shows ways of practical performance of three key methods that can be applied to assess the ecological status of small rivers. There are the classification of water quality (here: the aspect of organic load), river habitat assessments and monitoring of organic pollutants. The approach mentioned above was applied to assess the ecological state of small rivers in the territory of the city of Kiev. For the water quality classification, the saprobic indices have been related to reference conditions for sandy lowland rivers. The classification of results of the river habitat assessments was also based on a method usually applied in Germany. To detect organochlorine compounds, the use of the AOC method for first screenings is recommended here.

A comparative analysis of structural pattern of macrozoobentos communities as bioindicators of water quality (WQ) in water bodies of the Berezina River basin was carried out. Two types of metrics were analyzed: those based on species richness and diversity and based on the ratio of abundance of tolerant (intolerant) species and common abundance. The first was characterized by lesser sensitivity to the changes in WQ in gradient of sites studied. Multimetric indices calculated for the first type of metrics give a more accurate assessment of WQ.

The method of separate cultivation of Scenedesmus quadricauda (Turp.) Bréb. cenobia, which made it possible to establish relationship between resting, dead, and multiplying cells in the model population of the alga, was elaborated. The contribution of resting cells to the total numbers of the alga at all stages of the growth of its population accounted for 45−70%. The highest contribution of multiplying cells (up to 45%) to the total numbers of the alga was observed at the exponential stage of its growth. At all stages of the alga growth, the contribution of dead cells was not more than 20%. Dead cells were decomposed for 2−3 hours.

In a series of experiments, when the oil concentrations in the bottom sediments were < 0.10−0.17 g/kg of dry silt, the microbial communities are still capable of keeping their natural structure and are resisting the incoming pollution.

It is determined that the chronic influence of excessive quantity of allochthonous nitrogen in water has both direct and indirect influences on the vital functions of carp yearlings. The intensity of biosynthetic processes and supply with high-energy phosphoric compounds are changed, and processes of peroxide oxidation of lipids are increased under the influence of nitrogen. It is shown that increased growth of experimental fish takes place against the background of substantial deviations in the balance of accumulation processes, utilization and reservation of plastic and energy substances that may have an adverse effect subsequently, during wintering.
