Air pollution has been increasing rapidly because of the human-based activities, such as mining, construction, industrial work, which have accelerated since the industrial revolution. This acceleration is caused by not only the high demand for vehicles but also the existence of a high quantity of factories in order to meet people’s requirements. As a result, the concentration of pollutants, such as particular matter (PM10), nitrogen monoxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon dioxide (CO2), and ozone (O3), in the atmosphere have been increased by the consumption of fossil fuels. The presence of these pollutants in the atmosphere provides valuable information about air pollution. It is revealed by studies that air pollution has negative impacts on both the species and their habitat in terms of health and sustainability. In addition, the high rise of global mean temperature and acidic rains are related to air pollution directly. The purpose of this study to examine, analyze and provide graphical data about the level of NO, NO2, NOx on the scale of Turkey by separating into regions : Black Sea region, Marmara region, Aegean region, Mediterranean region, Central Anatolia region, East Anatolia region and Southeast Anatolia region. In this study, 2010-2018 was taken as a period, and the evaluation was made on the basis of Turkey's provinces. According to this study, it has been revealed that the quantity of nitrogen dioxide and their variations (NOx’s) has been decreasing over the years on the scale of Turkey.
