Abstract

The paper presents data on biomonitoring the pollution state of aquatic environments through the development of microalgae. The presented results are based on the correlation of basic parameters of the aquatic environment state. This includes the determination of microalgae species composition, quantitative characteristics of abundance and biomass, as well as a number of hydrochemical parameters. Additionally, integral indices of biodiversity such as Serens-Cherkanovsky, Margalef, Shannon-Weaver, Simpson, and Pielou were calculated and cluster analysis of the basic aquatic environment state was performed. The comparison of trends revealed that the studied water bodies possess unique characteristics. Overall, these water bodies are able to handle anthropogenic stress, which is demonstrated through self-purification processes. However, this phenomenon is slowed down in the case of the Nizhnekalmius reservoir.
