Determination of Algae Concentrations in Some Water Bodies in the Voronezh Region Using an «Algae Tarch» Fluorometer

Abstract

The purpose is to determine the dynamics of blue-green and green algae concentration during the season in different water bodies of the Voronezh region and to identify the factors influencing it. Materials and methods. Concentrations of blue-green and green algae were determined using an Algae tarch fluorometer in the following water bodies: a pond in the Central Park of Voronezh, a pond near the natural monument "Square by the Lake", Tambovskoye and Takhtarka Lakes in Pavlovsky district, the Don River in Verkhnemamonsky district. Results and discussion. Measurements of blue-green algae concentration and total algae concentration in a number of water bodies in the Voronezh region were carried out using an Algae tarch fluorometer. The influence of climatic conditions in 2020, as well as of the ongoing lake reconstruction works on the algae concentration was determined. The dynamics of algae concentration in the Don River from June to September 2020 was revealed. Conclusions. The dynamics of blue-green algae concentration from May to September has been revealed. It was determined that the drought conditions of 2020, as well as reconstruction work in the reservoirs of the Voronezh region affect the eutrophication of water bodies.
