STUDY OF CHANGES IN CONCENTRATION OF VARIOUS POLLUTANTS CAUSED BY ANTHROPOGENIC FACTORS IN ATMOSPHERIC AIR (CASE STUDY)

Background: One of the major global environmental challenges is atmospheric air pollution. Consequently, there has been a concerning increase in the incidence of pulmonary and respiratory diseases worldwide. It is critical to recognize that primary pollutants released into the atmosphere can undergo a series of secondary and tertiary chemical reactions influenced by various environmental factors. Aims: The presented paper is a review of the research conducted on changes in air quality during social protests, holidays, or natural events in the Georgian capital in 2023-2024. Methods: The research was carried out through sensors installed in different districts of Tbilisi. The investigation was carried out within the NATO SPS program project REACT. Results: Atmospheric air pollution was monitored at four stationary sensor sets on K. Cholokashvili, Nutsubidze Street, Chavchavadze Avenues, and the Old Tbilisi area. The change in air quality due to the shooting of fireworks and the earthquake that occurred was investigated. The results are presented in the article in the form of tables. Discussion: The concentration of all primary pollutants increases sharply against the background of anthropogenic activity. The concentration of particulate matter increases in the period leading up to the earthquake. Conclusions: The Case Study proved the great influence of anthropogenic factors and Natural phenomena on increasing the concentration of pollutants in the atmospheric air.
