India's capital Wakes Up to Toxic Haze Post Festival of Lights

On Tuesday morning inhabitants of the world's most polluted city found themselves exposed to extremely polluted air that was classified as the "severe" range.

Alarming Pollution Readings

Multiple areas of the city recorded an pollution measurement above 500, which represents a tenfold increase over the safe limit recommended by the World Health Organization.

Particular areas, concentrations of dangerous airborne particles soared to of 1,800, equating to 15 to 20 times exceeding acceptable levels.

Pyrotechnics Restrictions and Current Policy Shifts

Beginning in 2020, the government had maintained a total prohibition on the purchase and ignition of pyrotechnics during celebrations due to their significant contribution to the deadly smog that covers the capital as colder weather begins.

However earlier this year, the current local leadership petitioned the judicial authority to request a modification of the prohibition.

The suggestion was allowing "eco-friendly fireworks" – which have been criticized by environmental experts as being only about 30% less polluting – as a compromise between "heritage and public health".

Court Decision and Implementation

Much to the frustration of medical and ecological advocates, judicial authorities agreed to the proposal, specifying that environmentally conscious fireworks could be used during limited periods throughout the Diwali.

During the celebrations, there was extensive flouting of the regulated periods across the city, with insufficient monitoring regarding whether the fireworks being used were actually the supposedly greener type.

Several recording stations throughout Delhi recorded pollution reaching highest levels around late evening to some of the worst readings recorded during the festival in at least recent memory.

International Consequences

The proliferation of firecrackers during the celebrations also initiated a blame game with adjacent the neighboring country, with officials in Pakistan's the Punjab region partly blaming worsening pollution levels in their urban centers on pollutants traveling from across the border following the celebrations.

Long-Standing Environmental Problem

The dangerously high levels of pollution in the capital have continued as a significant issue for over a decade and a half, with the condition showing no improvement.

During the festival period, the amount of toxic particles in the air has been found to spike to 70% higher the most severe records ever documented in the Chinese city, which was formerly viewed as the globally most contaminated city.

Diverse Contamination Sources

The situation in the city is attributed to a convergence of different contributors including automobile exhaust, construction debris, development work, waste incineration and haze from crop residue ignition in neighbouring areas of Punjab and Haryana.

Within these states, agricultural workers routinely set their fields on fire to expedite field preparation, creating hazardous smog that remains stagnant over the metropolitan area as winter air descends.

Medical and Economic Impact

The economic and health impact on the nearly 33 million residents living in the metropolitan zone is substantial, according to various research.

These hazardous conditions leads to high levels of neurological, heart and circulatory and respiratory diseases, and can result in cancer.

The pollution is projected to be accounting for approximately 10k early fatalities per year in Delhi.
