Data on the content of the labile fraction of dissolved metals in surface water bodies located in different regions of the world are generalized in the paper. This fraction includes primarily free (hydrated) metal ions, their hydroxycomplexes, and complexes with inorganic ligands. This fraction can include some portion of metals in the composition of unstable complexes with organic ligands. The lability of metals can be considered as the main characteristics of their potential bioavailability. In turn, it depends on a set of processes occurring in aquatic ecosystems, including mainly hydrolysis, complexation involving dissolved organic matter (DOM), and adsorption on suspended matter and bottom sediments. Methodical approaches to the determination of the labile fraction of metals are discussed. It has been known that only some methods can be used for this purpose. The combined methods of its extraction and detection are often used. Data on the firmness of metal complexes with various groups of dissolved organic matter of surface waters responsible for the lability of metals are also generalized.

Paper deals with data on distribution and new findings of several species of cladocerans of gen. Diaphanosoma Fischer, 1850 (Crustacea: Cladocera) in the water bodies and water courses of Ukraine. Issues of their habitat sites in Ukraine regarding their main areals are discussed. Beside widely distributed Diaphanosoma brachyurum (Lievin, 1848) in Ukraine occur three more species: D. dubium Manuilova, 1964, D. orghidani Negrea, 1982 and D. mongolianum Ueno, 1938. The latter of them was found for the first time in the waters of Ukraine. Finding of D. dubium in Ukraine indicates expansion of its areal westward.

macrozoobenthos
taxonomic composition
Taxonomic composition of macrozoobenthos of the Danube lakes was studied over the years 2006-2012. Totally 196 taxa were revealed, among them 174 were identified to the species level. Dominating groups were: Chironomidae - 29, Gastropoda - 28, Oligochaeta - 26, Odonata - 22, Amphipoda - 14 species. All species occurred in the lake littoral, and in the sublittoral - 82 species. Maximal number of species (183) was registered in the Yalpug Lake, minimal (66) - in the Kytay Lake in 2006-2009. Owing to deterioration of ecological situation in the lake in 2012, their number dropped to 23. The number of Ponto-Caspian species in the lakes decreased from 43 that in the mid-twentieth century up to 20 species nowadays.

adaptation mechanisms
On the whole, 17 species of small-sized centric diatoms were revealed using the methods of light and scanning electron microscopy. Among them, five species (Aulacoseira subarctica, Cyclotella ocellata, Handmannia comta, Stephanodiscus minutulus, and Conticribra weissflogii) were found in water bodies of various urban agglomerations (Kiev and Zhitomir) for the first time. Their electron microphotographs, brief morphological description, and ecological and geographic characteristics are given in the paper. It has been found that the number of new species of Centrophyceae did not depend on the type of urban agglomeration. The presence of small-sized centric diatoms, and also of brackishwater species of the genus Thalassiosira Cl., in plankton of urban water bodies is one of the mechanisms of phytoplankton adaptation to anthropogenic load.

Spatial and seasonal distribution of heterotrophic and phosphate mobilizing bacteria in bottom sediments of the northwestern part of the Black Sea (the Odessa region) was analyzed in 2009-2012. It has been found that in bottom sediments the numbers of heterotrophic and phosphate mobilizing bacteria were several times higher than those in water column, whereas the concentration of phosphorus compounds in pore solutions was one order of magnitude higher than that in water column. The maximal concentration of heterotrophic and phosphate mobilizing bacteria in the upper layer of bottom sediments was observed in the coastal zone of Odessa Bay and in the sections subjected to the most intensive anthropogenic load. Relationship was established between the numbers of heterotrophic and phosphate mobilizing bacteria in bottom sediments and hydrochemical indices.

indices of trophic level and water quality
microcystins
The paper is dealt with the assessment of the modern trophic status and water quality of Lake Kroman in terms of physico-chemical parameters and in terms of the indices of phytoplankton development and functioning (temperature, gas and hydrochemical regime, nutrients, species composition and quantitative indices of phytoplankton development, chlorophyll content, potential photosynthesis, decomposition, BOD5, seston concentration, ChOD, dissolved and suspended forms of organic matter, and the presence of microcystin producing Cyanoprokaryota). The response of lake ecosystem to the increase in the intensity of anthropogenic load conditioned by the influence of the "Kroman" tourist complex is discussed.

Modern ideas on physiological-biochemical status and responses of the lipid system of algae under the impact of metal ions have been analyzed. It was shown that stress-adaptation syndrome of algae to the metal compounds both individual and modified by other environmental factors comprises: changes of structure and lipid composition of the cell membranes, changes of direction and intensity of the lipid and associated energy metabolism, changes of ratio of the lipids' classes, modification of the lipids peroxidation, general metabolism modification aimed at forming of new level of the adaptive status under the stress.

Paper describes experience of application of the method of identification of contaminants' class, which cause the bottom sediments toxicity for the benthic and planktonic invertebrates owing to the secondary water pollution. The method consists in study of the test-organisms responses to adding of the substances capable of binding of contaminants of the certain chemical class. This enables identification of the contaminants' class in a series of experiments. Possibility to use Chironomus riparius larvae and Daphnia magna juveniles for identification the freshwater sediments toxicity was substantiated.
