1. This study explores the association between ambient air pollutants (PM2.5, NO2, SO2, CO, and O3), meteorological factors (average temperature, diurnal temperature range, relative humidity, wind velocity, air pressure, precipitation, and hours of sunshine), and their interaction on confirmed case counts of COVID-19 in 120 Chinese cities.
2. Positive associations were found between the number of confirmed cases of COVID-19 and CO, PM2.5, relative humidity, and O3 after controlling for population migration. Negative associations were also found for SO2 and wind velocity both with and without controlling for population migration.
3. Air pollutants and meteorological factors had interactive effects on COVID-19 after controlling for MSI.
This article is a well-researched piece that provides an in-depth analysis of the interactive effects of ambient air pollutants-meteorological factors on confirmed cases of COVID-19 in 120 Chinese cities. The authors have used a negative binomial regression analysis to account for potential migration effects by including the migration scale index (MSI) from Wuhan to each of the 120 cities included in the model. The results show positive associations between the number of confirmed cases of COVID-19 and CO, PM2.5, relative humidity, and O3 after controlling for population migration as well as negative associations between SO2 and wind velocity both with and without controlling for population migration. Furthermore, it was found that air pollutants and meteorological factors had interactive effects on COVID-19 after controlling for MSI.
The article is reliable as it has been published in a reputable journal (Environ Sci Pollut Res Int.) which follows rigorous peer review processes before publication to ensure accuracy and validity of research findings presented in articles published therein.
