Air quality in Delhi-NCR deteriorated sharply on Monday, with average AQI levels reaching 366 across the capital, according to environmental monitoring data. The pollution spike followed intensive firework displays during Diwali festivities over the weekend, with particulate matter and combustion emissions significantly degrading atmospheric conditions across the region.
Fifteen air quality monitoring stations recorded AQI readings exceeding 400, entering the hazardous category where health impacts become severe even for healthy individuals. Sonia Vihar emerged as the most polluted location, registering an AQI of 449—classified as severe and requiring immediate health precautions.
The combination of firecracker emissions and seasonal atmospheric conditions created thick smog blanketing numerous areas throughout the region. Visibility was notably reduced in multiple locations due to the dense haze, affecting traffic and daily activities Monday morning. Meteorological conditions, including stagnant air masses and temperature inversions typical of late autumn in north India, have exacerbated the pollution situation.
Environmental authorities have urged residents in affected areas to limit outdoor exposure and adopt protective measures. Schools and offices in several districts implemented health advisories, while hospitals reported increased respiratory complaints Monday.
