The megacity Awakens to Dangerous Pollution Following Festival of Lights

On Tuesday morning citizens of the world's most polluted city were faced with inhaling severely hazardous air that registered in the "severe" category.

Extremely High Air Quality Readings

Various sections of the capital showed an AQI over 500, which represents 10x the safe limit recommended by the World Health Organization.

In some locations, levels of toxic particulate matter reached peaks of 1800, amounting to 15-20x above healthy limits.

Firecracker Prohibition and New Developments

For the past four years, officials had enforced a complete ban on the purchase and ignition of pyrotechnics during celebrations due to their substantial impact to the dangerous haze that engulfs the capital as winter sets in.

However earlier this year, the recently formed city leadership approached the supreme court to propose a relaxation of the restrictions.

The suggestion was allowing "eco-friendly fireworks" – historically doubted by environmental experts as being only about 30% reduced emissions – as a compromise between "tradition and environment".

Judicial Decision and Enforcement

Despite concerns of medical and ecological activists, judicial authorities complied with the request, stipulating that environmentally conscious fireworks could be used during limited time windows throughout the Diwali.

On Monday night, there was widespread flouting of the time restrictions across the city, with minimal regulation regarding whether the fireworks being used were actually the supposedly greener variety.

Several recording stations throughout the capital recorded air quality spiking around the night hours to some of the worst measurements seen during celebrations in at least three years.

International Implications

The widespread use of fireworks during the celebrations also triggered a controversy with neighbouring the neighboring country, with authorities in Pakistani the Punjab region partially attributing declining air quality in Lahore on hazardous particles coming from across the border following the celebrations.

Persistent Environmental Problem

Alarmingly severe readings of pollution in the capital have remained as a serious issue for fifteen-plus years, with the situation gradually deteriorating.

During celebratory seasons, the concentration of dangerous airborne contaminants in the environment has been documented to shoot up to 70% higher the worst readings ever documented in the Chinese city, which was previously considered as the world's most polluted city.

Multiple Contamination Contributors

The problem in the city is resulting from a convergence of various sources including heavy vehicle emissions, construction debris, building projects, rubbish burning and haze from crop residue ignition in adjacent states of farming communities.

In these regions, farmers routinely burn crop residue to expedite field preparation, producing hazardous smog that then gets trapped over the city as colder air arrives.

Health and Economic Impact

Both financial and medical consequences on the roughly thirty-three million residents living in the metropolitan zone is enormous, according to multiple research.

These hazardous conditions causes increased incidence of neurological, heart and circulatory and respiratory disorders, and can result in malignancies.

Air quality crisis is projected to be causing approximately 10k premature deaths each year in the capital.
