Abstract |
The Covid-19 blockade is playing an important role in reducing air pollutants across the country. The present work aims to analyze air pollutants such as particulate matter (PM10), Sulphur dioxide (SO2), Nitrogen dioxide (NO2) at Bilaspur Chhattisgarh in 3 Phases Pre-Lockdown phases, During Lockdown and Post-Lockdown in the same time frame i.e., (March 1st - May 31st). All data was taken from the Chhattisgarh Environment Conservation Board (CECB) (https://www.enviscecb.org/) and compared the data of pre, during, and post lockdown to check for increases and decreases in air quality. For these, we used different types of Air Quality Index (AQI) to conclude on quality of air, such as Indian AQI, Oakridge AQI, and Average AQI. Vyapar Vihar Bilaspur Air quality indexwas 56 but during the lockdown (March 1, May 31, 2020) it was reduced to 47, a decrease of 16% and after the lockdown (March 1, May 31, 2021) increases by approximately 9% i., 51. A global study suggests that during the blocking phase (March 1, May 31, 2020) it shows declination, but when the unblocking process begins the main pollutant shows gradually increasing. The current review demonstrates that implementing unlimited air contamination measures can bring immediate air quality benefits. |
