Abstract
In this study, it was aimed to investigate the effect of the applications of “stay home” and social movement restriction due to COVID-19 outbreak on air quality. In this descriptive cross-sectional study, measurement values of PM10, PM2.5, and SO2 variables in Kütahya province between 11th March and 25th May in 2019 and in 2020 were compared with 24-hour PM10, PM2.5 and SO2 mean limit values that are the air pollution criteria for Turkey and the World Health Organization (WHO). Between 11th March and 25th May in 2019, mean PM10 was 62.17±33.36 μg/m3, mean PM2.5 was 11.34±10.43 μg/m3, mean SO2 was 18.18±13.98 μg/m3, and mean air temperature was 11.14±4.58°C. Between 11th March and 25th May in 2020, mean PM10 was 42.25±26.20 μg/m3, mean PM2.5 was 16.69±8.77 μg/m3, mean SO2 was 6.93±5.36 μg/m3, mean air temperature was 13.27±6.00°C. Compared to the same period of the previous year, there is a decrease in PM10 and SO2 concentrations in Kütahya province while an increase is observed in PM2.5 concentrations.
