After Kolkata’s air pollution level surged past that of Delhi for the past seven days in a row, environmentalists and experts have called for a wider network of automatic air quality monitoring stations, news agency IANS reported. Experts and environmentalists suggested monitoring stations should be functional in the densely populated and traffic-heavy areas to capture a more accurate picture of the city’s air quality. 

Green technologist and environmentalist Somendra Mohan Ghosh said that Kolkata needed at least 20 automatic air quality monitoring stations across the metropolitan area to obtain reliable, real-time data.
