Covid-19 pandemic has adversely affected all the aspects of life in adverse manner; however, a significant improvement has been observed in the air quality, due to restricted human activities amidst lockdown. Present study reports a comparison of air quality between the lockdown duration and before the lockdown duration in seven selected cities (Ajmer, Alwar, Bhiwadi, Jaipur, Jodhpur, Kota, and Udaipur) of Rajasthan (India). The period of analysis is 10 March 2020 to 20 March 2020 (before lockdown period) versus 25 March to 17 May 2020 (during lockdown period divided into three phases). In order to understand the variations in the level of pollutant accumulation amid the lockdown period, a trend analysis is performed for 24 h daily average data for five pollutants (PM2.5, PM10, NO2, SO2, and ozone).

关于 Covid-19 大流行期间封锁对拉贾斯坦邦(印度)污染最严重城市空气质量影响的警句研究

Covid-19大流行以不利的方式对生活的各个方面产生了不利影响;然而,由于封锁期间人类活动受到限制,空气质量有了显着改善。本研究报告了印度拉贾斯坦邦七个选定城市(阿杰梅尔、阿尔瓦尔、比瓦迪、斋浦尔、焦特布尔、哥打和乌代浦尔)的空气质量比较。分析期为 2020 年 3 月 10 日至 2020 年 3 月 20 日(锁定期前)与 2020 年 3 月 25 日至 5 月 17 日(锁定期分为三个阶段)。为了了解封锁期间污染物积累水平的变化,对五种污染物(PM2.5、PM10、NO2、SO2 和臭氧)的 24 小时日平均数据进行趋势分析。Fig. a Graphical abstract 图形摘要
