As Tuesday dawned residents of this heavily contaminated metropolis encountered exposed to severely hazardous air that was classified as the "alarming" level.

Alarming Air Quality Measurements

Several parts of the city showed an AQI over 500, which translates to a tenfold increase over the healthy limit recommended by the WHO.

In some locations, levels of dangerous airborne particles reached peaks of 1,800, representing fifteen to twenty times exceeding healthy limits.

Pyrotechnics Prohibition and Recent Developments

For the past four years, authorities had maintained a complete ban on the distribution and bursting of firecrackers during the Festival of Lights due to their substantial impact to the hazardous haze that blankets the metropolis as colder weather sets in.

Yet recently, the recently formed regional administration appealed to the supreme court to seek a easing of the prohibition.

They proposed allowing "environmentally conscious pyrotechnics" – historically criticized by conservation groups as being only approximately one-third reduced emissions – as a compromise between "tradition and ecological concerns".

Legal Ruling and Implementation

To the disappointment of public health and environmental campaigners, the court complied with the proposal, stipulating that environmentally conscious fireworks could be set off during designated hours throughout the celebrations.

On Monday night, there was considerable flouting of the designated hours across the metropolis, with insufficient regulation regarding whether the firecrackers being used were actually the supposedly greener version.

Several air quality sensors throughout the capital recorded air quality peaking around the night hours to the most severe measurements recorded during the festival in at least recent memory.

International Consequences

Extensive ignition of fireworks during the festival also initiated a dispute with neighbouring the neighboring country, with representatives in Pakistani Punjab province partially attributing deteriorating air quality in their urban centers on hazardous particles coming from across the border following the events.

Chronic Pollution Issue

The dangerously high readings of atmospheric toxins in Delhi have persisted as a serious issue for fifteen-plus years, with the problem showing no improvement.

Around Diwali, the concentration of toxic particles in the atmosphere has been documented to increase dramatically to 70% higher the most severe levels ever measured in the Chinese city, which was previously regarded as the globally most contaminated urban center.

Diverse Contamination Sources

The problem in the city is caused by a combination of various sources including heavy vehicle emissions, construction debris, construction activities, rubbish burning and smoke from farm burning in adjacent states of Punjab and Haryana.

Throughout these areas, farmers regularly ignite agricultural waste to prepare for next season, creating toxic smog that remains stagnant over the metropolitan area as colder air descends.

Health and Financial Impact

Both financial and medical toll on the nearly 33 million residents calling home the capital region is significant, according to multiple studies.

The contaminated air causes increased incidence of neurological, heart and circulatory and breathing conditions, and can result in oncological diseases.

Environmental contamination is calculated to be accounting for ten thousand premature fatalities each year in Delhi.
