India's capital Awakens to Hazardous Smog Post Festival of Lights

As Tuesday dawned inhabitants of the world's most polluted city found themselves inhaling dangerously toxic air that fell into the "critical" level.

Alarming Air Quality Readings

Several parts of the city recorded an air quality index exceeding 500, which translates to a tenfold increase over the healthy level established by the WHO.

In some locations, levels of toxic particulate matter hit highs of 1,800, equating to 15-20x exceeding safe standards.

Fireworks Prohibition and Current Policy Shifts

For the past four years, the government had enforced a comprehensive restriction on the sale and use of pyrotechnics during celebrations due to their major role to the hazardous haze that blankets the capital as colder weather begins.

However recently, the current regional leadership petitioned the highest court to request a relaxation of the ban.

They proposed allowing "environmentally conscious pyrotechnics" – historically questioned by conservation groups as being only approximately one-third reduced emissions – as a balance between "heritage and environment".

Legal Verdict and Enforcement

Despite concerns of public health and environmental activists, judges complied with the request, mandating that environmentally conscious fireworks could be ignited during limited time windows throughout the Diwali.

On Monday night, there was extensive disregard of the regulated periods across the metropolis, with little regulation regarding whether the fireworks being used were actually the more environmentally friendly version.

Numerous recording stations throughout Delhi showed contamination reaching highest levels around late evening to extremely hazardous readings seen during celebrations in at least three years.

Cross-Border Implications

The widespread use of fireworks during Diwali also triggered a dispute with adjacent the neighboring country, with officials in Pakistani Punjab partially attributing worsening air quality in Lahore on contaminants originating in neighboring India following the festivities.

Chronic Pollution Issue

Alarmingly severe readings of pollution in the city have remained as a significant issue for fifteen-plus years, with the problem showing no improvement.

Around the festival period, the amount of dangerous particles in the air has been observed to spike to significantly exceeding the peak records ever measured in the Chinese city, which was once regarded as the globally most contaminated city.

Multiple Pollution Factors

This crisis in the capital is caused by a mix of different contributors including heavy vehicle emissions, construction debris, construction activities, waste incineration and smoke from farm burning in nearby states of farming communities.

Within these states, farmers routinely burn crop residue to prepare for next season, creating hazardous smog that becomes contained over the metropolitan area as cooler air arrives.

Medical and Financial Toll

Public health and economic consequences on the nearly 33 million inhabitants calling home the Delhi area is enormous, according to numerous research.

This pollution results in increased incidence of nervous system, heart and circulatory and lung conditions, and can result in malignancies.

Air quality crisis is estimated to be accounting for 10,000 premature mortalities annually in the capital.
