BACKGROUND: We aimed to investigate the relation between environmental air pollutants such as Particulate Matter 10 (PM10), Particulate Matter 2.5 (PM2.5), Sulfur Dioxide (SO2) on daily cases and deaths associated with SARS-CoV-2 infection.
METHODS: The ecological research examined the correlations of the air quality metrics and the data of COVID-19 cases and deaths from March 1, 2020 to March 1, 2021 in the central District of Tekirdağ Province in Türkiye.
RESULTS: During the study period, the average PM10 concentration was 32.57±17.86 μg/m3, PM2.5 was 20.68±11.31 μg/m3, SO2 was 11.28±13.42 μg/m3, and NO2 was 19.07±7.26 μg/m3. The SARS-CoV-2 case fatality rate in the study area during this period was 3.2%. Correlation analyses between air pollutants and SARS-CoV-2 cases and deaths revealed significant positive associations between SARS-CoV-2 cases (r=0.220 for PM10, P<0.001; r=0.290 for PM2.5, P<0.001; r=0.218 for SO2, P<0.001) and deaths (r=0.203 for PM10, P<0.001; r=0.289 for PM2.5, P<0.001; r=0.278 for SO2, P<0.001). Moreover, regression analysis revealed that ambient sulfur dioxide (SO2) levels significantly predicted both COVID-19 incidence and mortality.
CONCLUSION: PM10, PM2.5, and SO2, key parameters for assessing air quality, exhibit a positive relationship with the increasing number of daily SARS-CoV-2 cases and daily deaths in the study area.
