As Tuesday dawned citizens of the world's most polluted city found themselves exposed to severely hazardous air that was classified as the "alarming" range.

Extremely High Pollution Levels

Several parts of Delhi showed an pollution measurement exceeding 500, which equals 10x the safe level recommended by the global health authority.

In some locations, levels of dangerous airborne particles reached peaks of 1,800, amounting to 15 to 20 times above healthy levels.

Firecracker Ban and New Policy Shifts

Beginning in 2020, officials had enforced a total prohibition on the sale and use of firecrackers during Diwali due to their major role to the dangerous smog that covers the city as colder weather begins.

Nevertheless earlier this year, the newly elected local government approached the judicial authority to seek a easing of the ban.

They proposed allowing "green crackers" – historically criticized by environmentalists as being only roughly 30 percent lower impact – as a balance between "heritage and ecological concerns".

Legal Verdict and Reality

Much to the frustration of medical and ecological campaigners, judicial authorities agreed to the request, stipulating that green firecrackers could be ignited during limited time windows throughout the celebrations.

During the celebrations, there was considerable violation of the designated hours across the metropolis, with minimal monitoring regarding whether the firecrackers being used were actually the supposedly greener type.

Many monitoring devices throughout the capital registered air quality spiking around late evening to the most severe levels observed during Diwali in at least recent memory.

International Consequences

The widespread use of firecrackers during Diwali also initiated a dispute with neighbouring the neighboring country, with authorities in Pakistani Punjab pointing to worsening atmospheric conditions in the city of Lahore on hazardous particles traveling from across the border following the celebrations.

Chronic Pollution Issue

The dangerously high concentrations of atmospheric toxins in the city have continued as a serious problem for fifteen-plus years, with the condition continuing to worsen.

Around Diwali, the levels of toxic particulate matter in the environment has been found to spike to seventy percent above the most severe levels ever recorded in the Chinese city, which was formerly viewed as the world's most polluted city.

Multiple Contamination Contributors

This crisis in the city is caused by a combination of different contributors including transportation pollution, dust, development work, garbage fires and haze from crop residue ignition in neighbouring regions of Punjab and Haryana.

Within these states, farmers illegally ignite agricultural waste to clear them quickly, producing hazardous haze that remains stagnant over the capital as cooler air sets in.

Health and Financial Impact

The economic and health impact on the roughly thirty-three million people calling home the Delhi area is enormous, according to various research.

These hazardous conditions causes increased incidence of neurological, heart and circulatory and lung disorders, and can potentially cause cancer.

The pollution is calculated to be responsible for 10,000 premature fatalities annually in the city.
