The possibilities of new approaches to assessing the physiological adequacy of drinking water using biotesting methods are disclosed. Biotesting of waters, both depleted and enriched with potassium, sodium, calcium and magnesium, was carried out according to the indicators of acute water toxicity on freshwater fish Brachydanio rerio , genotoxicity on its blood cells, and chronic toxicity on Ceriodaphnia affinis . It was found that water samples with the optimal content of K⁺, Na⁺, Ca²⁺, Mg²⁺ do not exhibit toxicity, while in the samples in which the content of these elements is outside the range of optimal concentrations, chronic toxic and genotoxic effects are found.
