The COVID-19 pandemic, which spread primarily from the Wuhan city to other provinces of the People's Republic of China and then to other countries in the world, has created great changes in people daily life. In line with the measures taken by countries against this virus, practices such as using masks, not using public transport, staying isolated at home, semi-curfews and lockdowns have been observed. Although the loss of life caused by COVID-19 raises concerns around the world, the harms of air pollution to human health are much more frightening. Curfew practices, measures, and restrictions have been taken around the world to prevent the spread of COVID-19 have an extremely important effect on air quality. In Türkiye, where curfews and various travel restrictions are also implemented, human behaviours and living habits, which have a direct impact on pollutant concentrations in the atmosphere, are changed due to the COVID-19 Pandemic. Türkiye has followed different policies such as tightening the measures during the pandemic process and relaxing the measures when the number of cases decreased and starting the normalization periods. In this study, it is aimed to determine, analyse, and evaluate pollutant concentrations (PM₁₀, SO, NO) in 5 following periods representing the duration of implementation of curfew and other measures in Türkiye. While 16thMarch-31stMay represents the first curfew, 1stJune-31stOctober represents the normalization period, 1stNovember-15thMarch represents the second curfew period in which cases increase, 16thMarch-17thMay represents the third wave of coronavirus, and 18thMay-30thJune represents the period of gradual normalization and the removal of bans. In addition, these periods are also considered for the same dates in 2019 and 2020 to see relative changes. In Türkiye, an average of 2.08% increase in PM₁₀ concentrations in the curfew periods and 6.15% in the normalization periods is observed compared to the previous year. In SO, an average increase of 7.56% is observed in the curfew periods and an increase of 32.01% in the normalization periods. In NO, an average of 5.19% decrease was observed in the curfew periods and a decrease of 1.92% in the normalization periods
