Abstract

Scientists from Ancient Rome and Greece wrote about the possibility of using living organisms as indicators of certain natural conditions. According to modern concepts, bioindicators are organisms, the presence, quantity or developmental features of which serve as indicators of natural processes, conditions or anthropogenic changes in the environment. The ability of ecosystems of surface water bodies to self-purify is used by anthropogenic activities as a mechanism for wastewater treatment, but given the huge role of microalgae in the self-purification of the Kugart River, this article is devoted to the study of the ecological, indicator ability of the algal flora of the studied object. The ecological condition of the Kugart River was examined, indicating the ecological forms of algae, as well as the qualitative and quantitative composition of indicator species of algae downstream from the discharge of wastewater.
