Delhi Rises to Dangerous Haze Post Diwali

Tuesday brought inhabitants of the world's most polluted city found themselves inhaling dangerously toxic air that fell into the "severe" category.

Extremely High Pollution Measurements

Several parts of Delhi registered an air quality index above 500, which represents a tenfold increase over the recommended level established by the World Health Organization.

Certain monitoring stations, readings of toxic particulate matter reached peaks of 1800, equating to 15 to 20 times exceeding healthy levels.

Pyrotechnics Prohibition and New Changes

Since 2020, authorities had enforced a comprehensive restriction on the purchase and ignition of pyrotechnics during celebrations due to their substantial impact to the deadly pollution that engulfs the metropolis as the cold season sets in.

Nevertheless in recent months, the current local leadership approached the highest court to propose a modification of the prohibition.

The suggestion was allowing "eco-friendly fireworks" – previously criticized by environmentalists as being only about 30% reduced emissions – as a compromise between "tradition and public health".

Judicial Ruling and Reality

To the disappointment of medical and ecological activists, the court approved the appeal, mandating that eco-friendly pyrotechnics could be ignited during limited periods throughout the Diwali.

Throughout the festival evening, there was extensive flouting of the regulated periods across the city, with minimal regulation regarding whether the fireworks being used were actually the more environmentally friendly type.

Several recording stations throughout Delhi registered air quality spiking around late evening to some of the worst measurements seen during Diwali in at least the past three years.

Cross-Border Consequences

Extensive ignition of fireworks during the celebrations also triggered a controversy with neighbouring Pakistan, with officials in Pakistani Punjab partially attributing worsening atmospheric conditions in Lahore on pollutants coming from neighboring India following the events.

Persistent Pollution Issue

Extremely elevated concentrations of atmospheric toxins in the city have persisted as a major issue for fifteen-plus years, with the problem continuing to worsen.

During Diwali, the levels of hazardous airborne contaminants in the environment has been observed to shoot up to seventy percent above the most severe levels ever measured in Beijing, which was formerly viewed as the globally most contaminated urban center.

Diverse Contamination Contributors

The situation in Delhi is attributed to a convergence of multiple factors including transportation pollution, construction debris, development work, rubbish burning and pollutants from farm burning in nearby states of farming communities.

Throughout these areas, rural residents illegally ignite agricultural waste to expedite field preparation, generating dangerous haze that then gets trapped over the metropolitan area as cooler air descends.

Medical and Economic Consequences

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

The contaminated air leads to increased incidence of nervous system, heart and circulatory and lung diseases, and can potentially cause oncological diseases.

The pollution is calculated to be causing 10,000 early mortalities per year in Delhi.
