ABSTRACT=<p>In this study, we conducted an ecological study to examine their effects in the early phase of the pandemic (from December 2019 to February 2020) in China. We found that the associations between the average concentrations of NO<sub>2</sub>, SO<sub>2</sub>, and CO and the COVID-19 transmissibility are not statistically clear.</p>
