Abstract

Various studies have shown the positive impact COVID-19 had on the environment, but findings on different countries have yet to be reviewed together. The purpose of this paper is to perform a meta-analysis to provide a cross-country comparison of the impact of COVID-19 lockdown on air quality. 9 papers were chosen, providing data on at least 3 of the 6 major pollutants of some high-income and middle-income countries. A meta-analysis is then conducted to pool the results of multiple studies together to see if there is an overall trend. Data analysis demonstrates that the concentrations of PM2.5, PM10, NO2, SO2, and CO decreased and the concentration of O3 increased in most countries. Lockdown reduced air pollution significantly in many countries, especially in middle-income economies. Research on what caused the more significant air pollution reduction in middle-income economies could be an interesting topic for further studies.
