Air pollution had always been a serious concern on human health. With growing population and expanding industrialization air quality has deteriorated drastically in recent years. But the COVID-19 Lockdown which had halted the entire world from the developmental sector did have a considerable improvement on the environmental rejuvenation wherein air quality has improved to greater extent. Studies on air quality improvement were necessary to assess the level of impact. Tiruchirappalli district was chosen for this study and the Air Quality Index records were taken for five spells during 2020 and 2021. The AQI of 2020 lockdown period in the different stations recorded values ranging from 61 to 42 during the pre-lockdown period, the similar ranged from 52 to 33, 26 to 8 and 42 to 21 during the 1st lockdown 2nd lockdown and 3rd lockdown periods respectively. The mean values for all the five CAAQM stations of Trichy district during 2021 revealed that the AQI fell sharply from 50.8 to 16.1. The AQI fell gradually from 24.3 to 7.5, 40 to 22 and 51.3 to 32.7, respectively for the three periods of 4th lockdown, 5th lockdown and 6th lockdown periods. The sharp decline in the AQI values indicated that the level of pollution had been down phased, and the air has become cleaner in the lockdown period than before.
