Delhi's air quality plummets to 'very poor' as Diwali begins

Delhi's air quality index hit 391 on Friday. It was classified as 'very poor.' Millions were starting Diwali festivities.

Millions across India are celebrating Diwali. This Hindu festival of lights marks the triumph of good over evil.

But Northern India faces dangerous air pollution at the same time. Delhi's air quality index reached 391 on Friday.

This placed it firmly in the 'very poor' category. Mumbai's index hit 322 in late October.

Seasonal weather, crop burning, and Diwali firecrackers combine to worsen the pollution. Authorities warn levels could rise further as celebrations continue.

India's Supreme Court permitted certified 'green' firecrackers in Delhi for a limited period. These produce about 20 to 30 per cent fewer emissions than standard firecrackers.

But critics question whether green firecrackers will make a real difference. They worry conventional ones still come in from nearby states.
