新冠疫情期间无锡市环境空气质量分析

Analysis of Ambient Air Quality in Wuxi During the Corona Virus Disease 2019

通过对无锡市区环境空气污染物的连续监测,对新冠疫情期间环境空气质量进行研究分析。结果表明,2月疫情期间,无锡市环境空气质量同比与环比均有明显好转,AQI指数在24~80,均为优良天。这可能与全社会生产、生活、活动有极大变动有关,可指导空气污染防治工作的努力方向。从单项指标看,除O_(3)以外的其他5项指标均有不同程度的好转。这可能与O_(3)的产生、消除机理不同,也可能与疫情期间大量消毒产品的使用有关,这值得我们下一步深入探讨。

Through the continuous monitoring of environmental air pollutants in Wuxi urban area,the environmental air quality during the corona virus disease 2019 was analyzed.The results showed that the air quality improved significantly in February,the AQI index changed from 24 to 80,and every day was good.This may be related to the great changes in the production,life and activities of the whole society,and this could guide the direction of efforts in the prevention and control of air pollution.In terms of individual indicators,all five other indicators except O_(3) showed varying degrees of improvement.This should be different from the mechanism of O_(3) production and elimination,and also could be related to the use of large numbers of disinfection products during the epidemic,which deserved our further in-depth discussion.
