Toxic air enveloped Delhi for the fifth consecutive day, making it the most polluted city across the planet and prompting the authorities to hold an emergency meeting.
The air quality index (AQI) of Delhi was at '372', in the 'very poor' category at 8 am, according to the state-run System of Air Quality and Weather Forecasting And Research (SAFAR). Readings below 50 are considered safe, while anything above 300 is considered hazardous or 'severe'. Levels surged after people violated a ban on bursting firecrackers on Diwali last week and stubble burning by farmers spiked in areas adjoining Delhi.
