Summary Recently, 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 critical 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 negative 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. The goal of our study was to research polluting substances, such as carbon and nitrogen oxides in atmospheric air in Tbilisi area, namely Chavchavadze avenue and Varazis Khevi during relatively free traffic times. Thus, the main purpose of our study was to assess the level of air pollution in selected areas, namely the determination of nitrogen and carbon oxides concentrations and their monitoring in Tbilisi atmospheric air. Collected samples were analyzed using Picarro G2401 CRDS (carbon oxides, methane) and Eco Physics CLD 780 TR (nitrogen oxides). The study was performed on the basis of SMART|AtmoSim_LAB.
