On Tuesday morning citizens of this heavily contaminated metropolis found themselves exposed to dangerously toxic air that was classified as the "severe" category.

Alarming Air Quality Levels

Multiple areas of the city registered an pollution measurement over 500, which translates to ten times the safe level established by the global health authority.

Particular areas, levels of dangerous airborne particles reached peaks of 1,800, amounting to fifteen to twenty times above healthy levels.

Firecracker Ban and New Changes

For the past four years, authorities had implemented a complete ban on the sale and use of firecrackers during the Festival of Lights due to their major role to the dangerous smog that covers the capital as colder weather sets in.

Yet recently, the current regional administration approached the highest court to seek a modification of the ban.

Officials advocated for allowing "green crackers" – which have been questioned by conservation groups as being only approximately one-third reduced emissions – as a balance between "cultural practices and environment".

Legal Verdict and Reality

To the disappointment of environmental and health advocates, the court approved the request, mandating that environmentally conscious fireworks could be used during limited time windows throughout the celebrations.

Throughout the festival evening, there was widespread flouting of the designated hours across the metropolis, with minimal enforcement regarding whether the pyrotechnics being used were actually the more environmentally friendly variety.

Many recording stations throughout the city showed pollution peaking around the night hours to the most severe measurements observed during the festival in at least recent memory.

International Consequences

The widespread use of fireworks during Diwali also triggered a blame game with neighbouring the neighboring country, with representatives in Pakistani Punjab province pointing to deteriorating air quality in Lahore on contaminants traveling from across the border following the events.

Persistent Pollution Crisis

Extremely elevated readings of atmospheric toxins in the capital have remained as a major challenge for over a decade and a half, with the problem showing no improvement.

During celebratory seasons, the concentration of toxic particles in the atmosphere has been observed to increase dramatically to significantly exceeding the most severe readings ever documented in China's capital, which was once viewed as the planet's dirtiest city.

Diverse Contamination Factors

The problem in the city is caused by a mix of various sources including automobile exhaust, airborne particles, development work, garbage fires and smoke from agricultural fires in adjacent areas of neighboring agricultural zones.

Within these states, rural residents routinely burn crop residue to prepare for next season, generating toxic haze that then gets trapped over the city as colder air sets in.

Health and Economic Toll

The economic and health toll on the nearly 33 million people living in the metropolitan zone is enormous, according to numerous studies.

The contaminated air results in high levels of neurological, heart and circulatory and lung conditions, and can result in cancer.

Air quality crisis is projected to be accounting for ten thousand premature deaths annually in the city.
