“…The most important property of a natural system is the ability to maintain its original state or flow to another state, while maintaining internal bindings (inertia, plasticity). Stability of such systems is achieved by physical, mechanical and chemical transfer processes, dilution, sorption and migration of the substance [9]. This approach to definition of ecological well-being of the Shershnevskoe reservoir in Chelyabinsk region is used in our research [10].…”

In this article a “well-being” degree of the water supply source of a major industrial center (Chelyabinsk, Russia) is determined in compliance with criteria of the sustainable development goal 6 “Clean water and sanitation” (SDG 6). It is demonstrated that the Shershnevskoye reservoir corresponds to the main water quality indicators recommended by the SDG 6 and is the “good-quality” water body according to the national standards for maximum permissible concentrations for drinking water use during the entire period of the reservoir existence. The dynamics of pH level, mineralization, dissolved oxygen, nitrogen, phosphorus and heavy metals content in the water of the reservoir for the period from 1975 to 2020 was analyzed. Stable neutral-alkaline conditions in the reservoir water were revealed; a statistically significant decrease of mineralization, increase of dissolved oxygen content and a strong trend of mineral phosphorus growth are observed, which characterizes strengthening of photosynthetic processes and increase of productivity and anthropogenic eutrophication level of the water body. The risk factor for the reservoir ecological well-being is heavy metal content, especially iron, manganese and copper.

The issues of external influence on biological objects have interested mankind since ancient times. It can significantly affect vital activity of yeast cells. Their use for bioindication and quantitative determination of the rate of gas emission depending on composition of culture liquid makes it possible to use this process for bioindication of environment. In the article, on the basis of a developed machine for measuring the rate of carbon dioxide emission by yeast fungi, which makes it possible to use it in laboratory and field conditions, the values of the effect of mercury on the process of fermentation of culture medium by yeast are given. A method for express bioindication by yeast fungi of environmental pollution with mercury has been worked out. It serves as the basis for development of guidelines for identifying and controlling sources of chemical hazards during emergency response. The experiments have shown that the maximum effect on bioactivity of yeast is exerted by the HgCl2 salt with different concentrations, which leads to a decrease in the rate of CO2 emission and deterioration of yeast vital functions.
