On Diwali, Delhi's air quality deteriorated sharply, with more than 24 monitoring stations reporting an AQI exceeding 400, indicating hazardous pollution levels across the capital.
The Economic Times reported that Delhi woke up to a toxic air situation on Diwali, with the Air Quality Index (AQI) crossing the hazardous mark at numerous locations. Over 24 monitoring stations across the city logged AQI values above 400, a level that poses serious health risks to the public.
Such extreme readings are driven by a combination of firecracker emissions, stagnant weather conditions and already high baseline pollution in the capital. The surge in particulate matter and nitrogen oxides has pushed the air quality into the 'severe' category, prompting health officials to advise residents, especially children, the elderly and those with respiratory ailments, to limit outdoor exposure.
Authorities have urged citizens to use masks, keep windows closed and avoid unnecessary travel. The city’s pollution control board is expected to issue further advisories as the situation evolves, while environmental groups continue to call for stricter regulation of fireworks during festivals.
The episode underscores the recurring challenge Delhi faces each winter season, where festive celebrations often coincide with unfavorable meteorological patterns, amplifying the health impact of air pollution.
