Abstract: This study aims to assess and analyze the effect on air pollutants (PM10, PM2.5, SO2, NO2, NH3, Ozone) during different lockdown phases in Dewas, M.P. India. These different lockdown phases are classified as pre-lockdown (01 Jan – 24 Mar), lockdown (25 Mar – 31 May) and post lockdown (1 Jun – 31 Dec). The air pollutants dataset was acquired from the CPCB website from the duration of 2018 to 2022. A comparative analysis was employed to evaluate the distribution of air pollutants throughout the year including the lockdown phase. Furthermore, hypothesis testing was conducted using a z-test to ascertain the facts obtained through comparative analysis. Consequently, the outcomes revealed that the concentration level of particulate matter along with gaseous pollutants significantly reduced except for ozone during the lockdown phase.
