Summary: A novel coronavirus has impacted the global economy, environment, and social life. During the lockdown period, the concentration of volatile organic compounds (VOCs) significantly decreased, especially for benzene, toluene, ethylbenzene, and m-xylene. Furthermore, the closure of non-traffic sources during the lockdown resulted in improved air quality. However, the lifetime cancer risk for benzene exceeded the prescribed value in the pre- and post-lockdown periods.
