Title

SPATIO-TEMPORAL VARIATION STUDY OF AMBIENT AIR QUALITY IN NASHIK CITY AMID COVID 19 LOCKDOWN: A GIS APPROACH

Abstract

India placed countrywide limitations on individuals' freedom of travel during the final week of March 2020 to track the spread of the new coronavirus (COVID-19) (lockdown). India had a substantial drop in particulate matter (PM) concentrations despite its economy being shut down by regulations. In India, the concentration of air pollution and its consequent health impacts are quickly rising. This study was designed to analyse the spatial and temporal variations of particulate matter (PM2.5, PM10) concentrations in Nashik city, Maharashtra. The daily PM2.5 and PM10 concentrations monitored by the sensors at the different locations distributed in the study region were used for the analysis. The descriptive statistics indicate that the spatial mean of average PM2.5 concentrations ranged from 59.4524 μg/ m3 to 9.9034 μg/ m3 and average PM10 concentration ranged from 69.66 to 11.4906 μg/ m3. The maximum and minimum spatial variousness were observed in March 2021 (no lockdown) and June 2021 (fifth lockdown period). The study also analysed the PM2.5 and PM10 air quality index. The AQI value was determined according to the Government of India, Ministry of Environment, Forest and Climate Change. The result suggests that most of the area had the moderate to unhealthy category of PM2.5-AQI & PM10-AQI, which leads to severe breathing discomfort for people in the area. It was observed that the air quality level was worst during March 2021, when there was no lockdown and sound in June with the highly restricted lockdown. For the spatial analysis done with the help of QGIS, an Inverse Distance Weighted (IDW) interpolation technique is used. Furthermore, the overall result shows a decrement in the air quality index AQI during the lockdown compared to pre-lockdown.
