The Brihanmumbai Municipal Corporation (BMC) on Monday said that Mumbai’s air quality has shown significant improvement over the past two days, thanks to several measures taken to control pollution across the city and its suburbs.
According to Mumbai civic body, these measures include strict action against private construction sites and government projects that fail to follow pollution-control guidelines. Notices have already been issued to a number of sites, and the BMC has said that action will continue.
