Determination of the integral toxicity of water in terms of biotesting with a multisensor system sensitive to individual toxicants.

Possibility of applying a multisensor potentiometric system of the type of the 'electronic tongue' as a method for evaluating the toxicity of a water medium is considered. The multisensor system is preliminarily calibrated against samples with a known toxicity, determined by the biotesting method with the use of living organisms. It is shown that the thus obtained system is suitable for evaluating the quality of water samples in terms of the response of various test objects without direct use of living organisms.
