COVID-19 PANDEMIC STAY HOME PRACTICE: ITS EFFECT ON KÜTAHYA AIR QUALITY

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.

COVID-19 PANDEMİSİ EVDE KAL UYGULAMASI: KÜTAHYA HAVA KALİTESİNE ETKİSİ

Abstract

Bu çalışmada COVID-19 salgını nedeniyle “evde kal” ve toplumsal hareket kısıtlama uygulamasının hava kalitesine etkisinin incelenmesi amaçlanmıştır. Bu tanımlayıcı kesitsel araştırmada Kütahya il merkezinde 11 Mart-25 Mayıs 2019 ve 11 Mart-25 Mayıs 2020 tarihleri arasındaki PM10, PM2,5 ve SO2 değişkenlerine ait ölçüm değerleri Türkiye ve Dünya Sağlık Örgütü’nün (WHO) hava kirliliği kriteri olan PM10, PM2,5 ve SO2 değerlerinin 24 saatlik ortalama sınır değerleri ile karşılaştırılmıştır. 11 Mart 2019-25 Mayıs 2019 tarihleri arasında PM10 ortalaması 62,17±33,36 μg/m3, PM2,5 ortalaması 11,34±10,43 μg/m3, SO2 ortalaması 18,18±13,98 μg/m3, hava sıcaklığı ortalaması 11.14±4.58°C’dir. 11 Mart 2020-25 Mayıs 2020 tarihleri arasında PM10 ortalaması 42,25±26,20 μg/m3, PM2,5 ortalaması 16,69±8,77 μg/m3, SO2 ortalaması 6,93±5,36 μg/m3, hava sıcaklığı ortalaması 13,27±6,00°C’dır. Kütahya’da önceki yıl aynı dönem ile karşılaştırıldığında PM10 ve SO2 konsantrasyonlarında azalma olduğu görülürken PM2,5 konsantrasyonlarında artış görülmektedir.
