Aims. Synthesis of many years of experience with the features and problems of bioassays environmental components according to the certified methods and develop some solutions. Methods. With the test organisms of different trophic groups determined by the integral components of the toxicity of natural and industrial systems. We used the following organisms: Chlorella vulgaris, Daphnia magna, Ceriodaphnia affinis, Paramecium caudatum, Escherichia coli. Results. Interpretation of the results of bioassays, if possible, should take into account the natural "matrix", effects of stimulation, as well as organisms reactions, manifested before the death of individuals. Conclusion. In our opinion, requires better methodological framework, the creation of a data bank, reflecting the dependence of the "dose-effect", the effects of the combined action of pollutants, as well as integrated effect of factors.

Key words: bioassay, the integrated toxicity, natural and industrial systems.
