On Tuesday morning inhabitants of the planet's dirtiest urban center were faced with inhaling severely hazardous air that registered in the "alarming" category.
Various sections of Delhi showed an air quality index exceeding 500, which represents ten times the recommended level set by the WHO.
In some locations, readings of dangerous airborne particles soared to of 1800, amounting to 15-20x above acceptable limits.
Since 2020, officials had implemented a comprehensive restriction on the sale and use of pyrotechnics during the Festival of Lights due to their significant contribution to the hazardous haze that covers the capital as winter sets in.
Yet recently, the recently formed local administration appealed to the supreme court to request a modification of the restrictions.
Officials advocated for allowing "eco-friendly fireworks" – which have been criticized by environmentalists as being only approximately one-third lower impact – as a middle ground between "tradition and ecological concerns".
To the disappointment of environmental and health campaigners, judges approved the appeal, specifying that environmentally conscious fireworks could be set off during designated hours throughout the celebrations.
Throughout the festival evening, there was extensive disregard of the regulated periods across the metropolis, with little regulation regarding whether the firecrackers being used were actually the supposedly greener type.
Several monitoring devices throughout the city registered contamination reaching highest levels around midnight to the most severe readings observed during the festival in at least the past three years.
Extensive ignition of firecrackers during the festival also sparked a controversy with bordering the neighboring country, with officials in Pakistan's the Punjab region partially attributing deteriorating pollution levels in their urban centers on contaminants traveling from India following the events.
Alarmingly severe levels of pollution in the city have remained as a significant problem for fifteen-plus years, with the condition showing no improvement.
Near the festival period, the levels of dangerous particulate matter in the atmosphere has been documented to shoot up to significantly exceeding the peak readings ever measured in Beijing, which was once regarded as the globally most contaminated urban center.
The situation in Delhi is resulting from a convergence of different contributors including transportation pollution, construction debris, construction activities, rubbish burning and smoke from farm burning in adjacent areas of farming communities.
Throughout these areas, farmers illegally set their fields on fire to prepare for next season, generating toxic pollution that then gets trapped over the city as colder air arrives.
The economic and health toll on the approximately 33 million residents calling home the Delhi area is significant, according to multiple research.
This pollution results in elevated rates of neurological, cardiovascular and respiratory diseases, and can result in oncological diseases.
The pollution is calculated to be responsible for 10,000 untimely mortalities per year in the city.
