Abstract

The work provides a comprehensive environmental assessment of the eutrophic biogenic load on a water body using the example of the Gulf of Taganrog of the Sea of Azov. This study is carried out with the aim of a deeper understanding of the ecological state of the waters of the Gulf of Taganrog, the processes of its eutrophication. The assessment of the biogenic load on the water area is carried out. The conducted researches showed that the eutrophication of the Gulf of Taganrog northeastern part depends on the salinity, water temperature, ammonium, and nitrate and phosphate concentrations. The level of the internal and external loads of phosphorus in the waters of the Gulf of Taganrog is approximately equal.

Summary

Introduction

Waters eutrophication is a complex process, characterized by the nutrients enrichment, and the algae number increase This leads to undesirable changes in the waters quality of the water body, its biological diversity and the disruption of the sustainable water use. Waters eutrophication is a peculiar phenomenon of the ecosystem, which is achieved by enrichment with nutrients, which, as a rule, stimulates the growth and flowering of algae, and this, in turn, leads to a deterioration in the quality and condition of natural waters. In recent decades, this has become a global environmental problem. To develop measures to reduce eutrophication of the water area, first, it is necessary to understand how its processes
