Abstract
Abstract The present study investigates the effect of lockdown on ambient air quality of 16 Indian cities constituting the major hotspots for COVID-19 cases. The COVID-19 lockdown resulted in cleaner air in India. Significant reduction of nearly 62%, 52% and 69% are observed in PM10, PM2.5 and NO2 levels as compared to preceding years. However, there is no significant effect of lockdown on other gaseous pollutants (SO2 and O3). The lockdown in India was found to be an effective way to restrict the virus spread rate and measure control ambient air pollutant levels.
期刊介绍：
The Environmental Claims Journal is a quarterly journal that focuses on the many types of claims and liabilities that result from environmental exposures. The ECJ considers environmental claims under older business insurance policies, coverage and claims under more recent environmental insurance policies, as well as toxic tort claims. Exposures and claims from all environmental media are considered: air, drinking water, groundwater, soil, chemicals in commerce and naturally occurring chemicals. The journal also considers the laws, regulations, and case law that form the basis for claims. The journal would be of interest to environmental and insurance attorneys, insurance professionals, claims professionals, and environmental consultants.
