ABSTRACT

The COVID-19 pandemic has caused unprecedented disruptions worldwide, including the implementation of lockdowns and travel restrictions. This study examines the impact of COVID-19 lockdowns on ambient air quality in different countries. The study analyzes air quality data from various monitoring stations in different countries before, during, and after the lockdowns. The results indicate that the lockdowns have led to a significant reduction in air pollution levels, mainly due to reduced vehicular traffic and industrial activities. The study finds that the largest reductions in air pollution levels were observed in highly industrialized countries such as China and India, where air pollution levels are typically high due to heavy industries and transportation. In contrast, the impact of lockdowns on air quality was less pronounced in less industrialized countries with relatively lower levels of air pollution. Overall, this study highlights the effectiveness of lockdowns in reducing air pollution levels, providing evidence for policymakers to consider long-term strategies to maintain a cleaner environment.
