Lung-Wen Antony Chen, Lung-Chang Chien (both Environmental and Occupational Health), and Ge Lin (Epidemiology and Biostatistics) recently published an article, "Nonuniform Impacts of COVID-19 Lockdown on Air Quality over the United States," in Science of the Total Environment.

This paper analyzes data from long-term air quality monitoring stations across the U.S. and estimates reductions of criteria air pollutants during the first phase of lockdown in March-April 2020, due to the COVID-19 pandemic. Findings can inform future modeling studies that attempt to capture policy outcomes by simulating statewide emission reductions. Such information is also important for the post-pandemic air quality management.
