Delhi air quality 'severe' after Diwali as firecracker ban defied; PM2.5 hits 879 micrograms per cubic meter, nearly 59 times WHO limit

Delhi's air quality has plunged into the 'severe' category post-Diwali, with PM2.5 levels reaching 879 micrograms per cubic meter—nearly 59 times the WHO limit—after residents defied a firecracker ban, exacerbating the city's chronic pollution crisis, according to reports from local monitoring stations.

Delhi's air quality has deteriorated significantly following the Diwali celebrations, with the Air Quality Index (AQI) in several areas classified as 'severe'.2

PM2.5 levels soared to 879 micrograms per cubic meter, exceeding the World Health Organization's recommended limit by nearly 59 times.4

Residents are choking on smoke and fine particulate matter as the firecracker ban imposed by India's Supreme Court was largely ignored during the festivities.

New Delhi is one of the world's most polluted capitals, grappling with pollution from vehicular emissions, crop-residue burning, and industrial activities.

Millions celebrate Diwali with fireworks, releasing harmful particles into the air, worsening the already critical pollution levels.

Last month, the Supreme Court had restricted conventional firecrackers, permitting only 'green firecrackers' designed to minimize pollution. However, these still emit 65 to 70% of the pollution produced by traditional firecrackers.

The situation highlights the ongoing struggle against air pollution in the capital, particularly during the winter months when smog is prevalent.

Key Insight
“IQair, citing a government station, recorded PM2.5 levels at 879 micrograms per cubic meter in Mandir Marg, almost 59 times the WHO safe limit. Parts of Delhi-NCR surpassed the WHO's 24-hour average by over 50 times, underscoring the health hazard.”
