These changes are attributed to a combination of meteorological conditions and emission reductions, primarily from transportation sources. Regional differences in the sensitivity of PM2.5 to emission sources are demonstrated in this work.

Air Quality Improvement during COVID-19 Lockdown in Bangkok Metropolitan, Thailand: Effect of the Long-range Transport of Air Pollutants

Parichat Wetchayont et al.

Summary: The study explores the impact of COVID-19 outbreak and long-range pollution on air quality in Bangkok Metropolitan, Thailand. The results show that there were decreases in PM2.5, O-3, and CO concentrations during the lockdown period, while NO2 and SO2 concentrations showed increasing trends. The study also indicates a positive effect of the COVID-19 lockdown on surface air pollution.

Air pollution impacts of COVID-19-related containment measures

Guillaume P. Chossiere et al.

Summary: The COVID-19 outbreak led to a significant decrease in anthropogenic emissions globally, resulting in reduced NO2 concentrations and avoided premature mortalities. However, there were no corresponding reductions in PM2.5 and ozone levels. Targeted air quality policies are needed to reduce the global burden of air pollution, especially related to secondary pollutants.

Analysis of Air Quality during the COVID-19 Pandemic Lockdown in Naples (Italy)

Alessia Sannino et al.

Summary: The lockdown measures in Naples resulted in a significant reduction of NO2 pollution in both urban and suburban areas, with CO and SO2 showing greater reductions in urban or industrial districts. Particulate matter at ground level was also affected to a lesser extent, and there were interesting variations in atmospheric aerosol composition.

Impacts of the COVID-19 lockdown on air quality and its association with human mortality trends in megapolis Mexico City

Gurusamy Kutralam-Muniasamy et al.

Summary: The study found that concentrations of NO2, SO2, and PM10 decreased during the lockdown period in Mexico City, while CO, PM2.5, and O-3 concentrations increased. Compared to the average of 2015-2019, some air pollutants showed a reduction in concentration during the lockdown.

Does the COVID-19 lockdown improve global air quality? New cross-national evidence on its unintended consequences

Hai-Anh H. Dang et al.

Summary: This study provides an early assessment of the impacts of COVID-19 on air quality using cross-national data, finding that global concentrations of NO2 and PM2.5 decreased by 5% and 4% respectively. The decrease in air pollution may be attributed to mobility restrictions following lockdowns.
