The theory, practice, and methodology of bioindication and assessment of the ecological state of aquatic ecosystems were elaborated on the basis of long-term investigations of continental water bodies and watercourses of the countries of the Former Soviet Union and of the other countries of Europe, Asia, and Middle East. The ecological state of aquatic ecosystems was assessed in terms of abiotic and biotic components. Original indices and system of ecological mapping were put forward. The methods of the indication of the influence of climatic changes on the diversity of algae, and also integral tables essential to classify water quality from the ecological point of view, are presented.

Composition of humic substances and enzymatic activity of peloids of hyperhaline water bodies of the north-west coast of the Sea of Azov were studied. Considered peloids are characterized by low content of humus (0.53−1.54%), humic acids (0.18−1.39%) and humin (1.06−2.72%), very low and low enzymatic activity, except invertase (moderate activity).

microcystins
The effect of octyl- and nonylphenols on growth, photosynthesis and toxin production by the bloom-forming Cyanobacteria Planktothrix agardhii was investigated. Alkylphenols were shown to inhibit growth of algae, at this inhibition rate decreases over cultivation. One of the reasons is decrease of alkylphenols concentration because of abiotic and biological processes. Growth inhibition of P. agardhii by alkylphenols is accompanied by increase of photosynthetic pigments synthesis. Considered culture P. agardhii was shown to produce several microcystins, the main of which is demethylated microcystin-RR (dm-RR). Under alkylphenols-induced stress toxins production is stimulated and concentration of extra-cellular dm-RR increases.

Paper deals with data on forming of the systems of the secondary concentric membranes in the cells of Lemna minor L. from the Zbruch River under contamination of water by heavy metals. Correlation between the heavy metals content and cells' radius is established, as well as between their content and rate of membranes' duplication.

aldolase activity
Activity of aldolase in tissues of Mytilus galloprovincialis with different shell color has been studied. Mussels' shell color was measured by photographing and computer processing of digital pictures using Adobe Photoshop CS-3. Four color groups were identified: black, intermediate, dark and light brown. It has been shown that in gill of intermediate and dark brown mussels aldolase activity was lower than in black and light brown. This correlation is described by parabolic function. Aldolase activity in podium and hepatopancreas of differently colored mussels was similar. Reasons of this difference are discussed.

The peculiarities of the formation of radionuclide contamination in the above the ground and underground phytomass of Phragmites australis, Typha angustifolia, and Glyceria maxima were investigated. It has been found that in the underground organs of the studied plants 137Cs specific content was 9−15 times higher than that in their above the ground organs. In this case, 74−87% of the total content of 137Cs was registered in plant roots.

natural waters.
Results of the study of arsenic in natural waters of various types are generalized and considered in the paper. It has been shown that in the non-contaminated surface water bodies its content accounts for several micrograms per L. A high concentration of arsenic in surface and soil waters is typical for the regions of non-ferrous metals mining. Contamination of soil and well waters as sources of drinking water supply by this chemical element is a serious hazard to human health. Considerable attention is paid to the study of arsenic coexisting forms responsible for its toxicity for living organisms, including human beings. The main factors and processes influencing the state of arsenic in natural waters are considered. It has been shown that not only chemical factors (oxidation − reduction potential, pH, oxygen and organic matter content, and the presence of oxidizing and reducing agents), but also biological components of aquatic ecosystems (phytoplankton, higher aquatic plants, and bacteria) significantly influence transformation of its compounds. A comparative assessment of the toxicity of arsenic inorganic forms and products of its methylation is given in the paper. The significance of their determination from the ecological point of view is underlined.
