Delhi’s air quality deteriorates to ‘very poor’ category, likely to worsen after festival

Delhi’s air quality worsened to “very poor” on Diwali, with levels expected to reach “severe” due to firecrackers. The city woke up to smog-filled skies, with Anand Vihar recording “severe” pollution. Last year saw clearer skies due to fewer stubble-burning incidents and rain. PM2.5 levels were high, posing health risks. Delhi has banned firecrackers, with 377 teams enforcing the ban. Unfavourable conditions, along with local pollution sources, contribute to poor air quality. Peak pollution is expected from Nov 1-15 due to stubble burning in Punjab and Haryana.
