The megacity Awakens to Toxic Haze Post Diwali

On Tuesday morning inhabitants of the world's most polluted city were faced with inhaling severely hazardous air that fell into the "critical" range.

Record-Breaking Air Quality Levels

Several parts of Delhi showed an air quality index above 500, which represents a tenfold increase over the recommended level set by the global health authority.

Particular areas, concentrations of toxic particulate matter soared to of eighteen hundred, representing 15-20x higher than healthy standards.

Fireworks Prohibition and Recent Changes

For the past four years, officials had implemented a total prohibition on the purchase and ignition of pyrotechnics during Diwali due to their major role to the deadly pollution that blankets the city as the cold season begins.

Nevertheless recently, the recently formed local leadership petitioned the highest court to seek a easing of the restrictions.

The suggestion was allowing "environmentally conscious pyrotechnics" – historically questioned by conservation groups as being only about 30% less polluting – as a balance between "cultural practices and public health".

Judicial Decision and Reality

To the disappointment of public health and environmental advocates, judicial authorities approved the request, mandating that green firecrackers could be set off during designated time windows throughout the celebrations.

On Monday night, there was extensive disregard of the time restrictions across the metropolis, with minimal monitoring regarding whether the fireworks being used were actually the eco-friendly type.

Several air quality sensors throughout the capital registered air quality reaching highest levels around late evening to the most severe measurements seen during celebrations in at least recent memory.

International Consequences

The proliferation of pyrotechnics during the celebrations also triggered a controversy with neighbouring the neighboring country, with authorities in Pakistan's Punjab province partially attributing deteriorating air quality in their urban centers on pollutants originating in neighboring India following the celebrations.

Persistent Environmental Crisis

The dangerously high levels of pollution in the capital have continued as a serious challenge for over a decade and a half, with the condition continuing to worsen.

Near Diwali, the amount of dangerous particulate matter in the atmosphere has been found to increase dramatically to significantly exceeding the worst levels ever recorded in Beijing, which was previously considered as the world's most polluted city.

Multiple Contamination Contributors

The problem in Delhi is resulting from a mix of various sources including automobile exhaust, construction debris, building projects, waste incineration and smoke from farm burning in nearby areas of farming communities.

Throughout these areas, agricultural workers routinely burn crop residue to prepare for next season, producing toxic smog that then gets trapped over the capital as cooler air descends.

Health and Financial Impact

Both financial and medical impact on the approximately 33 million residents residing in the capital region is enormous, according to various research.

This pollution causes elevated rates of neurological, cardiovascular and breathing disorders, and can even lead to malignancies.

Environmental contamination is calculated to be causing approximately 10k untimely fatalities per year in the capital.
