Due to the lack of central heating and chemical industry, in addition to the emissions from coal-fired enterprises such as power plants and the pollution transported from surrounding rural biomass burning activities, vehicle emissions are responsible for the most important pollution source affecting the air quality and public health in Wuhan (Daoru Liu, J o u r n a l P r e -p r o o f 5 2020). Compared with the corresponding periods, the rate of good days (AQI < 100) increased by 37.4%, which means that during the lockdown, the air quality in Wuhan had no significant effect on human health, and only some pollutants may have had a weak impact on the health of a small number of unusually sensitive people.	./cache/cord-344423-jhdfscyw.txt	./txt/cord-344423-jhdfscyw.txt
