India's capital Rises to Hazardous Haze Post Celebrations

As Tuesday dawned inhabitants of this heavily contaminated metropolis found themselves breathing extremely polluted air that registered in the "critical" range.

Alarming Air Quality Measurements

Several parts of Delhi showed an pollution measurement exceeding 500, which translates to ten times the healthy limit set by the WHO.

Certain monitoring stations, readings of PM2.5 and PM10 soared to of 1800, equating to fifteen to twenty times higher than healthy levels.

Fireworks Ban and Recent Changes

Beginning in 2020, officials had maintained a total prohibition on the distribution and bursting of firecrackers during celebrations due to their major role to the hazardous haze that engulfs the metropolis as winter begins.

However in recent months, the newly elected local government petitioned the highest court to request a modification of the prohibition.

The suggestion was allowing "green crackers" – historically criticized by environmentalists as being only approximately one-third lower impact – as a balance between "cultural practices and ecological concerns".

Judicial Decision and Implementation

Much to the frustration of environmental and health advocates, judges agreed to the appeal, stipulating that environmentally conscious fireworks could be ignited during limited time windows throughout the Diwali.

Throughout the festival evening, there was extensive violation of the designated hours across the city, with little regulation regarding whether the fireworks being used were actually the eco-friendly version.

Many air quality sensors throughout Delhi showed air quality spiking around late evening to some of the worst levels observed during celebrations in at least three years.

International Implications

The proliferation of pyrotechnics during Diwali also sparked a dispute with adjacent Pakistan, with authorities in Pakistan's Punjab partially attributing declining pollution levels in the city of Lahore on pollutants originating in across the border following the festivities.

Long-Standing Pollution Issue

Extremely elevated concentrations of pollution in the capital have remained as a serious challenge for more than 15 years, with the situation gradually deteriorating.

Around celebratory seasons, the levels of dangerous airborne contaminants in the air has been found to increase dramatically to 70% higher the worst records ever recorded in Beijing, which was previously considered as the world's most polluted city.

Multiple Contamination Factors

This crisis in Delhi is resulting from a convergence of multiple factors including transportation pollution, dust, building projects, rubbish burning and pollutants from crop residue ignition in adjacent regions of Punjab and Haryana.

In these regions, farmers illegally ignite agricultural waste to expedite field preparation, producing dangerous pollution that remains stagnant over the capital as cooler air arrives.

Medical and Economic Impact

Both financial and medical impact on the roughly thirty-three million people calling home the capital region is significant, according to various investigations.

These hazardous conditions causes elevated rates of nervous system, cardiovascular and lung diseases, and can potentially cause cancer.

The pollution is calculated to be causing 10,000 premature fatalities per year in Delhi.
