Also, the relationships between the air pollutants and meteorological variables during the three periods were investigated. The results showed that there was significant improvement in air quality during the lockdown. Compared to the pre-lockdown period, the concentrations of NO2, PM2.5, PM10, and...
This study concerns the relationship between air quality, economic wealth, and COVID-19 diffusion and mortality around the world. Using different data sources, we show that the level of air quality, in terms of particulate (PM 2.5) concentrations, does not significantly contribute to explain the...
Assessing whether long-term exposure to air pollution increases the severity of COVID-19 health outcomes, including death, is an important public health objective. Limitations in COVID-19 data availability and quality remain obstacles to conducting conclusive studies on this topic. At present, publicl...
To prevent the escalation of COVID-19 transmission, China locked down one-third of its cities, which strictly curtailed personal mobility and economic activities. Using comprehensive daily air quality data in China, we evaluated the impacts of these measures in terms of the Air Quality Index (AQI...
Only one study conducted in the North China Plain showed no significant change in air quality before and after shutdowns took place (Wang et al., 2020a). Although general COVID-related decreases in the concentrations of air pollutants have been shown in major US cities and around the world...
This study evaluates air quality during the partial lockdown of Shanghai, the largest city in China, and the broader Yangtze River Delta region. It was found that daily concentrations of PM2.5, PM10, SO2, NO2, and CO during the lockdown period were reduced by 9%, 77%, 31.3%, 60.4%,...
