Dynamics of quantitative and weight-dimensional characteristics of mussels Mytilus galloprovincialis Lam. and mytilaster Mytilaster lineatus Gmel. in the bottom settlements and periphyton of the concrete traverses in three coastal areas of the Odessa bay (nearby the Lanzheron cape, northwest section of the Black Sea, Ukraine) has been studied. These habitats were to a different extent isolated from the open sea by hydrotechnical coast-protective constructions. On the basis of density, weight-dimensional structure and individual biological characteristics of these mollusks in the considered habitats, filtration potential of their settlements under anthropogenic transformation of the coastal zone have been calculated.

Paper deals with nutrition and trophic relations of juvenile of the aboriginal fishes in the Sula bay, where the main portion of the spawning and fattening areas of the Kremenchuk reservoir are located. Trophic competition by zooplankton between juvenile bream, roach and silver bream, caused by low biomass of zooplankton communities, was revealed.

Anthropogenic impact on the water bodies leads to destruction of aerobic bacterial communities in the bottom sediments and formation of anaerobic ones. As a result bottom sediments become a source of secondary pollution and emission of methane into the atmosphere.

The process of sulfate reduction in bottom sediments of 23 lakes of different trophic levels was investigated. It has been found that in summer in fresh water bodies the numbers of sulfate reducing bacteria, the rate of the process of sulfate reduction, and the content of hydrogen sulfide varied over a wide range increasing from oligotrophic to eutrophic lakes. The main ecological factors influencing the process of sulfate reduction were revealed.

The influence of the Ariel detergent in the concentrations of 0.1, 1, and 10 mg/L on the dynamics of the numbers, chlorophyll a and carotenoids content, and on the oxygen productivity of the microalgae Dunaliella salina (Chlorophyta) and Plagioselmis prolonga (Cryptophyta) was investigated. It has been found that P. prolonga is more sensitive to the influence of the detergent as compared to D. salina. The activity of the toxicant increased with increasing its content in the medium.

Protein composition of the blood serum of the most widely distributed freshwater fishes of the West Podillya (carp, crucian carp, perch and pike) has been studied. Interspecific differences of albumins, a, β and γ-globulins content in the blood serum of the considered fish species have been studied. Certain differences in relation of the protein fractions in fishes from different small rivers have been revealed. Variation of the fraction protein composition as fish response to the environmental impact has been considered. Such variations may be used for biomonitoring of the aquatic ecosystems.

The peculiarities of the accumulation of 90Sr and 137Cs by higher aquatic plants of the Kiev Reservoir since 1991 until 2008 are analyzed in the paper. The specific activity of both radionuclides decreased. However, in recent years the specific activity of 137Cs decreased more rapidly than that of 90Sr, as a result of which the ratio between 90Sr and 137Cs increased. The right bank section of the Kiev Reservoir is more contaminated by 90Sr and 137Cs than its left bank section.

Results of the study of the coexisting forms of aluminum in surface water bodies of different types (reservoirs, lakes, and rivers) are discussed in the paper. It has been found that the distribution of Al(III) among suspended and dissolved forms depends not only on the content of suspended matter in the water, but also on its nature (mineral or organic suspended matter). Relationship between the mass of suspended matter and the content of aluminum in the composition of suspended matter was not established. The concentration of Alsusp increased in the case of a predominance of mineral suspended matter, which was observed on the example of river waters. The dissolved forms of aluminum were represented mainly by its complex compounds with dissolved organic matter of various chemical nature and molecular mass. The content of aluminum labile fraction varied over a wide range and increased from spring until summer. Either anionic, or neutral compounds predominate among the complexes of Al(III) with dissolved organic matter, which depends on the peculiarities of the component composition of organic matter in water bodies. The complexes of Al(III) with dissolved organic matter are formed mainly at the expense of the compounds with a rather low molecular mass (≤ 2 kDa).
