On Tuesday morning inhabitants of the world's most polluted city found themselves inhaling extremely polluted air that fell into the "critical" level.

Alarming Air Quality Levels

Various sections of the city showed an air quality index over 500, which translates to ten times the recommended limit set by the WHO.

In some locations, levels of toxic particulate matter soared to of eighteen hundred, representing fifteen to twenty times higher than safe standards.

Fireworks Prohibition and New Changes

Since 2020, authorities had enforced a total prohibition on the sale and use of fireworks during Diwali due to their substantial impact to the hazardous smog that blankets the metropolis as winter begins.

However in recent months, the current city government petitioned the supreme court to request a relaxation of the restrictions.

They proposed allowing "eco-friendly fireworks" – which have been doubted by conservation groups as being only approximately one-third less polluting – as a compromise between "cultural practices and environment".

Court Ruling and Implementation

To the disappointment of environmental and health activists, judicial authorities complied with the proposal, stipulating that green firecrackers could be ignited during limited hours throughout the festival.

On Monday night, there was considerable violation of the designated hours across the city, with minimal enforcement regarding whether the firecrackers being used were actually the eco-friendly type.

Numerous recording stations throughout Delhi recorded pollution spiking around late evening to some of the worst readings seen during the festival in at least the past three years.

Regional Implications

The proliferation of fireworks during the festival also sparked a dispute with neighbouring the neighboring country, with authorities in Pakistani Punjab partly blaming worsening atmospheric conditions in Lahore on hazardous particles originating in across the border following the events.

Chronic Pollution Issue

Extremely elevated concentrations of air contamination in the city have remained as a significant issue for over a decade and a half, with the problem showing no improvement.

Around the festival period, the levels of dangerous particulate matter in the environment has been found to shoot up to significantly exceeding the peak levels ever documented in Beijing, which was previously viewed as the world's most polluted city.

Diverse Contamination Sources

The problem in the city is attributed to a combination of different contributors including heavy vehicle emissions, construction debris, building projects, garbage fires and haze from crop residue ignition in nearby areas of neighboring agricultural zones.

Within these states, rural residents routinely ignite agricultural waste to prepare for next season, creating dangerous pollution that then gets trapped over the metropolitan area as colder air arrives.

Health and Economic Consequences

The economic and health consequences on the nearly 33 million inhabitants residing in the metropolitan zone is substantial, according to multiple studies.

These hazardous conditions causes high levels of nervous system, cardiovascular and lung diseases, and can result in malignancies.

Air quality crisis is calculated to be responsible for 10,000 untimely mortalities each year in Delhi.
