Delhi Rises to Dangerous Smog After Diwali

Tuesday brought inhabitants of the planet's dirtiest urban center were faced with inhaling extremely polluted air that was classified as the "severe" range.

Record-Breaking Pollution Measurements

Various sections of Delhi registered an air quality index above 500, which translates to 10x the healthy level recommended by the WHO.

In some locations, readings of PM2.5 and PM10 hit highs of 1800, amounting to 15 to 20 times exceeding safe levels.

Pyrotechnics Restrictions and Recent Changes

For the past four years, authorities had implemented a total prohibition on the distribution and bursting of firecrackers during the Festival of Lights due to their substantial impact to the deadly pollution that covers the metropolis as colder weather sets in.

Nevertheless recently, the recently formed city leadership petitioned the supreme court to propose a relaxation of the ban.

Officials advocated for allowing "green crackers" – historically doubted by environmentalists as being only roughly 30 percent lower impact – as a middle ground between "tradition and public health".

Legal Verdict and Enforcement

Despite concerns of public health and environmental campaigners, judicial authorities approved the proposal, mandating that eco-friendly pyrotechnics could be ignited during limited periods throughout the celebrations.

During the celebrations, there was extensive disregard of the designated hours across the capital, with minimal monitoring regarding whether the pyrotechnics being used were actually the eco-friendly version.

Several air quality sensors throughout the capital showed air quality peaking around the night hours to the most severe levels recorded during the festival in at least three years.

Cross-Border Consequences

The widespread use of firecrackers during Diwali also initiated a blame game with neighbouring the neighboring country, with representatives in Pakistan's Punjab province pointing to worsening pollution levels in their urban centers on pollutants traveling from across the border following the events.

Chronic Environmental Problem

The dangerously high concentrations of atmospheric toxins in the city have remained as a major challenge for over a decade and a half, with the condition gradually deteriorating.

Near the festival period, the levels of hazardous particulate matter in the air has been observed to increase dramatically to 70% higher the worst readings ever documented in the Chinese city, which was formerly considered as the planet's dirtiest metropolis.

Various Contamination Factors

This crisis in the capital is resulting from a combination of multiple factors including heavy vehicle emissions, dust, development work, rubbish burning and haze from agricultural fires in nearby states of farming communities.

In these regions, agricultural workers illegally burn crop residue to expedite field preparation, generating dangerous smog that remains stagnant over the metropolitan area as cooler air sets in.

Public Health and Economic Impact

The economic and health consequences on the roughly thirty-three million people calling home the capital region is substantial, according to various research.

The contaminated air results in elevated rates of neurological, cardiovascular and lung conditions, and can even lead to cancer.

Air quality crisis is estimated to be causing ten thousand premature fatalities annually in the capital.
