Tuesday brought citizens of the world's most polluted city encountered exposed to dangerously toxic air that fell into the "severe" category.

Extremely High Air Quality Readings

Multiple areas of the city showed an pollution measurement exceeding 500, which represents ten times the safe threshold recommended by the WHO.

In some locations, readings of toxic particulate matter reached peaks of 1,800, representing fifteen to twenty times above acceptable limits.

Pyrotechnics Prohibition and New Changes

Since 2020, officials had enforced a complete ban on the sale and use of fireworks during the Festival of Lights due to their significant contribution to the hazardous smog that blankets the city as winter approaches.

However recently, the current regional leadership petitioned the supreme court to seek a relaxation of the restrictions.

The suggestion was allowing "environmentally conscious pyrotechnics" – historically doubted by environmentalists as being only approximately one-third less polluting – as a balance between "tradition and ecological concerns".

Court Decision and Implementation

Despite concerns of medical and ecological campaigners, the court agreed to the request, stipulating that green firecrackers could be set off during designated periods throughout the celebrations.

Throughout the festival evening, there was extensive disregard of the time restrictions across the city, with minimal enforcement regarding whether the firecrackers being used were actually the eco-friendly version.

Several air quality sensors throughout the city recorded pollution peaking around late evening to extremely hazardous measurements seen during Diwali in at least recent memory.

International Implications

The widespread use of firecrackers during Diwali also triggered a blame game with neighbouring the neighboring country, with authorities in Pakistani Punjab province partly blaming deteriorating pollution levels in Lahore on hazardous particles traveling from neighboring India following the events.

Persistent Environmental Issue

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

During the festival period, the concentration of dangerous airborne contaminants in the air has been observed to spike to 70% higher the peak records ever recorded in China's capital, which was formerly considered as the planet's dirtiest city.

Multiple Contamination Sources

The problem in Delhi is caused by a mix of multiple factors including heavy vehicle emissions, airborne particles, building projects, waste incineration and haze from crop residue ignition in neighbouring regions of farming communities.

Within these states, agricultural workers illegally ignite agricultural waste to expedite field preparation, creating hazardous haze that remains stagnant over the capital as cooler air descends.

Health and Economic Consequences

The economic and health toll on the roughly thirty-three million people residing in the metropolitan zone is significant, according to numerous investigations.

This pollution leads to increased incidence of neurological, heart and circulatory and respiratory conditions, and can result in cancer.

Air quality crisis is projected to be responsible for 10,000 untimely mortalities each year in the city.
