Abstract： Based on the ambient air quality data of fireworks and firecrackers prohibited and non-prohibited areas in Changzhou City from January 24 to 25， 2020， the effect of fireworks combustion on air quality was analyzed. The results show that concentrated discharge of fireworks and firecrackers will lead to a rapid increase of particulate matter concentration in the ambient air， which can lead to an increase of PM10 and PM2.5 by 7.1 times and 5.2 times， respectively. Therefore， banning fireworks and firecrackers can effectively improve the ambient air quality.
