Due to the COVID-19 pandemic, the precautions taken in the early period of the pandemic have had a significant impact on the reduction of air pollutants. In this research, the changes in the concentrations of some air pollutants (PM10, NO2, SO2, CO, O3) concentrations have been investigated and evaluated between March 15 - May 31, 2019 and March 15 - May 31, 2020 in Turkey. According to the results, PM10, NO2 and SO2 concentrations decreased by up to 75%, 80% and 77% respectively. However, there has been an increase in CO and O3 concentrations in many cities. Pearson’s correlation analysis showed that there is a strong relevance between NO2 - CO and O3 - CO concentrations in the lockdown period. In addition, with the precautions, the positive correlation between PM10 and NO2 and between SO2 and CO increased, and the negative correlation between PM10 and O3 decreased.

Covid-19 Kapanma Önlemlerinin Türkiye’deki Hava Kirleticilerine Etkisi

Öz

COVID-19 nedeniyle pandeminin erken döneminde alınan önlemler, hava kirleticilerinin azaltılmasında önemli bir etki yaratmıştır. Bu araştırmada, Türkiye'de 15 Mart-31 Mayıs 2019 ve 15 Mart31 Mayıs 2020 tarihleri arasında bazı hava kirletici (PM10, NO2, SO2, CO, O3) konsantrasyonlarındaki değişimler araştırılmış ve değerlendirilmiştir. Sonuçlara göre PM10, NO2 ve SO2 konsantrasyonları sırasıyla
%75, %80 ve %77'ye kadar düşmüştür. Ancak birçok şehirde CO ve O3 konsantrasyonlarında artış tespit edilmiştir. Pearson korelasyon analizi, kapanma döneminde NO2-CO ve O3-CO konsantrasyonları arasında güçlü bir ilişki olduğunu göstermiştir. Ayrıca alınan önlemlerle PM10 ile NO2 ve SO2 ile CO arasındaki pozitif korelasyon artmış, PM10 ile O3 arasındaki negatif korelasyon azalmıştır.
