“Pollution in the city rose to its highest levels since air quality data monitoring began last June. The System of Air Quality Weather Forecasting and Research (SAFAR), which has been taking readings at 10 locations in Mumbai, measured the air quality index (AQI) at 325, which falls in the ‘very poor’ category, on Friday morning. By evening, it rose to 341, which was equal to Delhi’s. The previous highest pollution level was recorded at 313 on the day after Diwali, November 12, 2015.” Hindustan Times
