“…As the activities, discoveries, and uses of energy have manifested in the form of urbanization, green revolution, industrialization, communication, transport, and the comfortable mode of living, the generation of a variety of waste products particularly air pollutants takes place [ 2 ]. Along with these, desertification of soil also leads to air pollution due to increased amount of dust in air [ 3 – 5 ]. Air pollution is more complex than most other environmental challenges.…”

In the whole world, most of the air polluted cities were normalized during the COVID-19 lockdown but after the lockdown, the air pollution is continuously increasing day by day. In the present study, we assessed the air quality at the selected sites of Jaipur city after the COVID-19 lockdown from October 2020 to February 2021 to quantify the enhancement in air pollution. The obtained data was processed using air quality index (AQI), principal component analysis (PCA) and pearson correlation matric (PCM). The obtained data were also compared with National Ambient Air Quality Standards (NAAQS). Values of particulate matter (PM 10 , PM 2.5 ) were found beyond the limits of NAAQS (100 µg/m 3 , 60 µg/m 3 ) while the values of gaseous pollutant such as SO 2 , NO 2 , and CO was found below the limits of NAAQS (80 µg/m 3 , 80 µg/m 3 , 4.0 mg/m 3 ). Based on AQI, air quality of site 1 (114.80) and site 2 (110.48) was found severely polluted while air quality of site 3 (70.47) was found moderately polluted. Based on PCA, the highest loading factor was declared to PM 10 and the lowest loading factor was SO 2 . The study concludes that by adopting the control measures of particulate matter and periodical transport lockdown, air pollution can be minimised.
