Delhi's air quality exceeds 50‑fold WHO safe level as firecracker ban ignored

Air pollution in Delhi surged to more than 50 times the World Health Organization’s safe limit after residents ignored the Supreme Court’s 10 p.m. deadline for firecrackers on Deepavali night. At 11 p.m. on November 8, the Delhi Pollution Control Committee recorded a PM2.5 concentration of 760.99 µg per cubic metre in Akshardham, about 50.73 times the WHO 24‑hour permissible level of 15 µg. In Anand Vihar the same hour saw 767 µg per cubic metre, roughly 51.13 times the limit, while Jawaharlal Nehru Stadium registered 702 µg, about 46.8 times higher. The city’s overall air quality remained in the “very poor” category, with many areas classified as “severe”. PM2.5 particles are fine enough to enter the lungs and bloodstream, causing respiratory and other health problems. Winter in the Indo‑Gangetic Plains typically brings higher pollution because lower wind speeds and dropping temperatures trap pollutants. Stubble burning in October‑November adds a fresh plume of smoke, and the usual emissions from vehicles and dust combine with firecracker smoke to worsen the haze.

Context

Winter air‑quality spikes in Delhi are common due to weather that limits dispersion and agricultural burning in nearby states. The WHO limit is set to protect public health, and levels this high can trigger severe health advisories.
