ABSTRACT

Industry based township Asansol is always experiencing polluted environmental conditions in respect to the air quality. The present study is based on the measurement and analysis of air quality parameters to identify the intensity of pollution in this township. In this work, eight (08) stations of Asansol Township have been selected for measuring the air quality parameter through Temtop M2000C Air Quality Monitor. Data on PM2.5, PM10, Particles and CO2of the study sites were taken into consideration for the analysis. Temporal variation of CO2 was observed (p < 0.01) in a significant level but no statistically significant variation was noticed among these sites. ANOVA (Two ways) represents that the rate of CO2 and particles decreased significantly during the month of May’20 because of adopting lockdown that restricted human mobility. Besides this, all types of social, economic, industrial and urban activities suddenly paused that are the main sources of CO2 emission and its concentration in the atmosphere. Because of these, nature took adequate advantage and showed improvement in the ambient air quality during the outbreak of COVID-19. It has been observed that the vegetation cover in some areas of the township like Lahmeyer park, Nehru Park, Shatabdi Sishu, Udyan, Spandan Recreation Park, Gunjan Ecological Park, Vivekananda Park etc. did not allow the atmospheric CO2 level to have a deep dip as the previous CO2 level in these sites were not very high due to carbon storage potential of the floral species present. The aim of the present work is to analyse the different air quality parameters during the period of COVID-19 lockdown in Asansol Industrial Township and to find out the degree of improvement in the air quality of this area.
