Delhi Faces Severe Air Pollution and Worst Diwali Eve Smog in Ten Years

Delhi Encounters Record-Breaking Pollution Levels

Residents in India's capital encountered dense smog and poor visibility on Sunday morning following a night that recorded the worst air quality for a Diwali eve in a decade. Official metrics from India's Central Pollution Control Board documented a very poor air quality index reading of 362 on Saturday, while separate reports noted levels approaching the severe threshold at 383.

Understanding the Causes Behind the Smog

Environmental data indicates that vehicular emissions and agricultural stubble burning across the neighboring states of Punjab and Haryana heavily contribute to the persistent haze. Furthermore, traditional festive celebrations involving the widespread ignition of firecrackers significantly intensify the ongoing pollution across the urban center.

Government Response and Official Forecasts

In anticipation of the worsening conditions surrounding the Hindu festival of lights, regional authorities directed local educational institutions to transition to online learning formats. Officials also strongly advised local workers to operate remotely from their residences.

Forecasters anticipate that the air quality will deteriorate further into severe categories as festivities continue. Meanwhile, independent monitoring organizations such as Swiss evaluator IQAir designated the capital as the most heavily polluted major city globally on Saturday.
