The article presents the results of a set of biological testing methods (bioassays) in order to select the most effective for determining toxic and genotoxic properties of the various categories of water. The set of bioassays were included techniques using as test objects of representatives of major trophic links of the aquatic ecosystems - bacteria, ciliates, crustaceans, mollusks, fish, plants, and also Drosophila flies, which are a classic bioassay for determining of the genotoxic and mutagenic effects.
First assessment is carried out with using a specially developed criteria which allow obtain a comprehensive characteristic of bioassays. The testing results of bioassays were identified effective methods of biotesting for toxicological evaluation, standardization and quality control of waste, surface and drinking water. The most sensitive for the action of a large range of chemical substances and effective for using in water conservation practice was bioassay on Ceriodaphnia affinis.
