    Snippet: Meanwhile, although the air quality improvement during this period was unprecedented, the air pollution levels during the lockdown remained high. For example, the PM2.5 concentration in locked down cities was still more than four times higher than WHO considers safe (10 µg/m 3 for the annual mean) (WHO, 2005) , even though almost all non-6 For example, the morbidity cost of air pollution is found to be around two-thirds of mortality costs in Chi.....
