Qualitative and Quantitative Composition of Biodiversity in the Ponds Based on the Species Composition of Algae

Among the complex of anthropogenic factors, one of the leading places is occupied by the "water factor" associated with pollution of water sources, shortcomings in water purification and disinfection. Discharge of insufficiently treated and untreated wastewater into watercourses predetermines abnormal changes in their chemical composition and degradation of biocenoses. Municipal wastewater contaminated with organic and nitrogen-phosphorus-containing compounds, as well as bacteria and viruses, also contribute to the pollution of water bodies.
