The quality of water in the centralized drinking water supply of the population, artesian water from the pump-rooms of Kiev and packaged non-carbonated drinking water produced by various companies was studied with the help of a complex of animals and vegetable test organisms. The criterion for assessing the quality of these waters was the integral index, the index of general toxicity, which allowed them to be classified as "non-hazardous" to "very dangerous".

 

Key words: biotesting, general toxicity index, drinking water categories, drinking water.

 

Introduction. In recent years, in connection with the intensification of anthropogenic pollution of the hydrosphere, the problem of quality drinking water has become a priority for mankind. Every year, tens of thousands of new pollutants add to the multimillion-dollar composition of pollutants of surface waters. Even when they are in very low concentrations in drinking water, they, as a result of the action of a known phenomenon of synergism, can have a toxic effect on the consumer. Determination of the chemical composition of water can not take this factor into account, and therefore does not give an objective assessment of the quality of drinking water. To solve this problem, the Institute of Colloidal Chemistry and Water Chemistry of the NAS of Ukraine for the first time used methods of complex biotesting of drinking water quality [1 - 3].

The purpose of this paper is to compare the results of the biotesting of waters of various origins obtained with the help of a complex of animals and plant test organisms. Comparative characteristics allow us to identify the safest waters consumed by humans. The quality of such drinking water is physiologically high, since it should not contain anthropogenic pollutants ...
