The city of Kırıkkale, which gained importance with the industrial facilities established in the Republican period, began to receive immigration from the surrounding regions and beyond in the 1920s and 1930s. The ever expanding industrial facilities that were on the outskirts of the city at the time became part of the urban area as the city grew bigger. The city, trapped in a valley topographically, was developed in the east-west direction as it has a defective structure in the north and south. The density and severity of air pollution occurring in the low-lying city is high compared to its surroundings. The change in air pollution in the city of Kırıkkale between 2018 and 2019 was investigated based on the number of dwellings, population size and density, fuel type, industrial facility presence and traffic. This study is important because it is the most up to date of its kind. While the amount of SO2 and PM10 was high in 2018, CO values increased in 2019 as well. The number of lost data is high in 2018 and 2019. The reasons for this include failure of the measuring devices due to the lack regular maintenance; power cuts…etc. In order to fully measure the air pollution and air quality of the city, measurement stations should be installed at different points, supported by mobile measurement tools, fossil fuel consumption without standard features should be reduced and people should be kept informed about air pollution values in certain parts of the city.
