Delhi Faces Severe Air Pollution Crisis Post-Diwali With AQI Exceeding 500 Amid Firecracker Use and Construction Dust

Delhi is facing a worsening air pollution crisis exacerbated by multiple factors including the use of firecrackers during Diwali, construction activities, and regional agricultural stubble burning. Despite Supreme Court restrictions on firecracker usage, residents largely ignored the rules, causing PM2.5 levels to spike to hazardous levels. Experts have noted that even "green" firecrackers contribute significantly to particulate matter, while meteorological conditions like stagnant winds worsen pollution. Construction contributes substantially to the problem by releasing dust and emissions, with construction-related activities accounting for 25-30% of Delhi's total PM10 load during winter. Authorities have initiated measures such as drone-based photogrammetry surveys to revamp parks and improve urban green spaces, which may help mitigate pollution effects in the long run. Political tensions have also risen, with accusations between Delhi and Punjab governments regarding sources of pollution, highlighting enforcement challenges and public disregard for health advisories.
