The biochemical method and procedure to assess toxicity of sea water and biocides standard solutions using the diatom species Phaeodactylum tricornutum and the green alga Dunaliella salina as test-organisms are proposed. The intensity of the lipid hydroperoxidations is a test-reaction. Solution toxicity criterion is a content of these substances in culture liquid in comparison with control cultures.

The article deals with the mathematical models which can be used for description of the processes of changes in surface and underground waters quality under intensive anthropogenic loading. A possibility of construction of the universal mathematical model is shown. Results of numerical experiments are presented graphically.

Investigations of periphytic algae vegetating in the cooling pond of the Chernobyl Nuclear Power Station (NPS) after the accident have been carried out. It has been found that periphytic algae occurred widely, were highly diverse in their species composition and abundant in the cooling pond. A total of 128 species of periphytic algae belonging to five divisions was found in the cooling pond in 1995. Community dominants were blue-green, filamentous green algae, and diatoms. Periphytic algae with morphological anomalies have been found.
Microphytobenthos of the Southern Bug Lower Reaches

Microphytobenthos of the Southern Bug lower reaches, as well as quantitative indices and production of benthic algal communities, have been studied depending on different factors (type of bottom sediments, depth, phytoplankton development etc.). Trophic status of the Southern Bug lower reaches has been determined in terms of the level of microphytobenthos development.

Macrozoobenthos of the Danube water bodies has been studied. It has been found that abundance of the macrophytobenthos severely decreased in recent years. Species belonging to the Caspian faunistic complex gradually disappear from the macrozoobenthos composition, the structure of benthic cenoses is simplified, their production-decomposition indices are lower than those in the Danube River and the Sasyk reservoir. Total degradation of aquatic ecosystems is conditioned by the integrated ecologically unjustified economic utilization of aquatic and biological resources of these water bodies.

In the vicinity of three underwater mountains in the Indian Ocean, myctophid fishes, despite the dispersed type of their distribution, can occur in aggregations (at least by night) consisting of fishes belonging to the same species and similar in size. Different indices of aggregation were calculated for four mass species. Distance between fishes in aggregations, as well as distance between aggregations were calculated using the above mentioned indices.

The estimation of water quality of Lake Hanka (Far East) on the basis of four ecological-sanitary indices (content of chlorophyll a for plankton, phytoplankton biomass, chemical oxygen absorption, and sediment concentration) has been done by hydrooptical methods. A possibility of qualitative waters separation based on dissolved organic matter by some coefficients of diversity has been considered. The area of dispersed phase (boundary "suspended matter/water") per a unit of water volume was estimated.

The magnesium requirement of the alga Oscillatoria Vauch. is strongly determined of each concrete density of light flow, and increase with down-fall of light intensity within the interval 275−0 μ;E/m2·sec−1. The highest values of growth and biomass are observed at the highest values of light intensity and C:Mg ratio in nutrient solution. The increasing of algae magnesium requirements in the interval 275−26 μ;E/m2·sec−1 is connected with need of dark respiration and photosynthesis stimulation at down-fall of light flow.

Positive effect of the irreplaceable amino acids mixture (leucine, isoleucine, arginine, histidine, lysine, cysteine, methionine, treonine) on the carp larvae viability, growth and development has been established. The complex of amino acids from blue-green algae has also increased the silver carp larvae viability. The larvae survival was 86.6% at the dose of 5.0 mg/l in experiment, and 58.4% in control.

Chronic low radioactivity (silt as its source) has the effect of changes in fractional composition and physico-chemical properties of cytosol proteins of blastodermal cells in carp' embryos. Metalthyoneines are synthesized in the blastoderm as a response to contamination of water environment with radionuclides and metal compounds. Due to SH-ligands, they form complexes with radionuclides and cations of metals, and in that way protect the embryo's organism against the irradiation damage.

Results of radioecological monitoring of Lake Yezerishche (Vitebsk region, of Byelarus) performed during 1988−1992 are presented. In 1988 fairly high values of Cs-137 specific activity in the lake water reached 1.74−3.48 Bq/l; this, as further control has shown, was connected to shore contamination in 1986 and following years. Distribution of Cs-137 and Sr-90 in the components of the lake ecosystem for monitoring years had been also analyzed.
