Abstract
Hydrosphere collects and accumulates the most anthropogenic and natural pollutants released to atmosphere or lithosphere. Polluted water affects life activity of both individual organisms and the water ecosystems. For adequate estimating of natural waters state and quality, the different methods of research, including the study of physical, chemical, and biological processes that occur in the aquatic ecosystems were used. The kinetic approach was applied to study the complexity of redox processes in the aquatic medium, redox state of water, and its ability to self-purify both in the surface water objects of the Republic of Moldova and modeling systems. For this purpose, the redox active components in natural waters and their seasonal dynamics were studied by detecting the hydrogen peroxide, OH radicals, and inhibition capacity of natural waters.
