To investigate any impact of control measures taken by the government to reduce the spread of COVID-19 disease on daily
air pollution levels were investigated. Daily data of PM10, PM2.5, NO2, CO, SO2 and O3 measured at 14 ambient air quality
measurement stations in İzmir province between 1 January 2018 and 30 June 2020 were analyzed. In order to evaluate the
relationship between air pollution and COVID-19, each year was divided into three periods: the period before the pandemic
measures (January 1 - March 15), the period when strict measures were implemented (March 16 - May 31) and the normalization
period (June 1 - June 30). Changes in the air pollution level in 2020 was studied and compared to the values within the same
period in 2018 and 2019. It was observed that the decrease in air pollution levels in general was not reflected in PM10 and PM2.5
values. However, a decline in other pollutants both in the period when control measures are taken and during the normalization
period.
