Toxic smog blankets New Delhi as Diwali firecracker smoke worsens air quality

New Delhi is experiencing severe air pollution due to toxic smog from firecrackers used during the Diwali festival. The air quality index has dropped into the "severe" category, with particulate matter levels reaching seven times the World Health Organization's safety limit. Despite a ban on traditional firecrackers since 2017, many residents continue to use them, worsening the pollution crisis. New Delhi, with over 33 million people, is often ranked among the world's most polluted cities, especially during winter when crop burning and cooler temperatures trap smoke. The air quality issues are compounded by emissions from industries and coal use for electricity. Studies suggest that air pollution contributes to over a million deaths in India each year, with tiny particles posing serious health risks.
