The goal of our study was to research polluting substances of atmospheric air. Atmospheric air and exhaust gas analysis in Tbilisi area. Determining concentration of nitrogen oxides In Tbilisi ambient air. In recent years, air pollution and related problems attract more and more attention. The ambient air has an essential role among other components of biosphere and its importance is invaluable for all living organisms. Ambient air pollution has become a crytical problem with industrial development over the world. Amount of harmful exhausts in the atmosphere increases as a result of technological progress and the concentrations of certain components significantly exceed their permissible thresholds. Scientifically confirmed, that the atmosphere pollutants, such as carbon, nitrogen oxides (NOX), dust particles, volatile organic compounds at high concentrations has negativ impact on human health and material values, causes various diseases, including cancer. Increasing air pollution adversely affects the environment, destroys ecosystems, air pollutants influence the climate, cause negative processes in the protective ozone layer increase ozone contamination in low troposphere and contribute to the greenhouse effect. Air pollution in Georgia is associated with auto transport, energy sectors, industrial and agricultural sectors. The main source of pollution is the road transport and energy. Dust and nitrogen oxides are the basic pollutants that are scattered from the industrial sector in the atmosphere. Thus, the main purpose of our study was to assess the level of pollution in Tbilisi atmospheric air. Namely the determination of nitrogen oxides concentrations and their monitoring in Tbilisi atmospheric air. The work was performed on the basis of SMART | AtmoSim_LAB. The laboratory investigates air pollution in Tbilisi.
