Delhi Awakens to Dangerous Pollution Following Festival of Lights

Tuesday brought inhabitants of the world's most polluted city encountered breathing extremely polluted air that fell into the "critical" range.

Extremely High Air Quality Readings

Multiple areas of Delhi showed an air quality index exceeding 500, which translates to 10x the healthy limit set by the World Health Organization.

In some locations, readings of dangerous airborne particles hit highs of 1800, representing 15 to 20 times exceeding healthy limits.

Fireworks Prohibition and Current Policy Shifts

For the past four years, the government had maintained a complete ban on the distribution and bursting of fireworks during celebrations due to their major role to the hazardous haze that engulfs the city as winter begins.

Nevertheless earlier this year, the current local leadership petitioned the supreme court to request a modification of the prohibition.

Officials advocated for allowing "environmentally conscious pyrotechnics" – previously criticized by environmentalists as being only approximately one-third lower impact – as a balance between "cultural practices and public health".

Judicial Verdict and Reality

Much to the frustration of environmental and health activists, judges complied with the appeal, mandating that green firecrackers could be set off during designated time windows throughout the festival.

On Monday night, there was widespread disregard of the designated hours across the capital, with little enforcement regarding whether the pyrotechnics being used were actually the supposedly greener version.

Several air quality sensors throughout Delhi showed pollution reaching highest levels around midnight to some of the worst measurements seen during Diwali in at least the past three years.

Cross-Border Implications

The widespread use of fireworks during Diwali also triggered a blame game with adjacent the neighboring country, with officials in Pakistan's Punjab province partly blaming worsening atmospheric conditions in their urban centers on contaminants originating in neighboring India following the festivities.

Long-Standing Environmental Problem

The dangerously high readings of atmospheric toxins in the city have continued as a serious issue for over a decade and a half, with the condition continuing to worsen.

Near the festival period, the concentration of toxic airborne contaminants in the atmosphere has been found to shoot up to seventy percent above the most severe readings ever measured in the Chinese city, which was previously regarded as the world's most polluted city.

Various Contamination Contributors

The problem in Delhi is caused by a combination of multiple factors including transportation pollution, airborne particles, construction activities, garbage fires and pollutants from crop residue ignition in neighbouring regions of Punjab and Haryana.

In these regions, farmers routinely ignite agricultural waste to clear them quickly, creating hazardous pollution that becomes contained over the metropolitan area as colder air sets in.

Public Health and Economic Consequences

Public health and economic impact on the approximately 33 million people living in the capital region is enormous, according to numerous studies.

This pollution causes elevated rates of neurological, heart and circulatory and lung diseases, and can result in malignancies.

Air quality crisis is calculated to be causing ten thousand early deaths per year in the city.
