Air pollutants that cause environmental pollution put human beings and other ecosystems at risk. In many cities of our country, the problem of air pollution caused by industrial and heating has reached significant levels. In this study, the temporal and seasonal distribution of air pollutant parameters in the city center of Van province, its concentrations, and the relation of pollutant parameters with temperature are discussed according to the permissible limit values and recommendations for solution for the city are included. The winter season is harsh in terms of topographic and geographic location of the city and the average temperature of the city is lower than the country average. Therefore, pollutants from the fuels used for heating purposes have a large share in air pollution. However, industrial pollutants of industrial origin are found in very low concentrations in the city due to the fact that the city is one of the less developed industrial cities. Frequent use of low-energy high-sulfur coal derivatives for heating purposes and incorrect combustion techniques reveal the reason for the heavy pollution seen in the winter months. Therefore, the use of cleaner fuels such as natural gas is one of the most suitable solutions for this problem. With the provision of lines to the districts that do not reach the natural gas, the use of natural gas, which is considered as a safe and clean fuel, should be expanded. Furthermore, at the points where the line does not reach, the controls on the poor-quality fuel should be started from the sales points and the users should be informed and their losses should be explained.
