Delhi Wakes Up to Hazardous Haze Post Diwali
As Tuesday dawned citizens of the planet's dirtiest urban center were faced with breathing dangerously toxic air that registered in the "critical" level.
Alarming Air Quality Levels
Various sections of the city registered an air quality index over 500, which equals ten times the safe threshold established by the World Health Organization.
In some locations, readings of toxic particulate matter reached peaks of 1800, amounting to 15 to 20 times above safe levels.
Fireworks Prohibition and Recent Policy Shifts
Since 2020, officials had implemented a comprehensive restriction on the sale and use of fireworks during the Festival of Lights due to their major role to the dangerous smog that engulfs the metropolis as the cold season approaches.
Yet earlier this year, the newly elected city administration petitioned the supreme court to seek a relaxation of the restrictions.
The suggestion was allowing "environmentally conscious pyrotechnics" ā historically criticized by environmentalists as being only approximately one-third reduced emissions ā as a middle ground between "heritage and environment".
Legal Verdict and Reality
To the disappointment of public health and environmental campaigners, judges approved the proposal, mandating that green firecrackers could be ignited during specific time windows throughout the celebrations.
On Monday night, there was considerable disregard of the designated hours across the city, with insufficient regulation regarding whether the firecrackers being used were actually the supposedly greener version.
Many air quality sensors throughout the capital registered air quality spiking around midnight to some of the worst readings recorded during celebrations in at least three years.
Regional Implications
The widespread use of pyrotechnics during Diwali also triggered a controversy with adjacent Pakistan, with authorities in Pakistan's Punjab pointing to declining air quality in their urban centers on hazardous particles traveling from across the border following the events.
Persistent Environmental Crisis
The dangerously high levels of pollution in Delhi have remained as a significant problem for more than 15 years, with the condition gradually deteriorating.
During the festival period, the levels of toxic airborne contaminants in the air has been observed to shoot up to seventy percent above the most severe records ever documented in the Chinese city, which was previously viewed as the world's most polluted city.
Various Pollution Factors
The problem in the city is resulting from a mix of various sources including transportation pollution, dust, construction activities, rubbish burning and haze from farm burning in neighbouring areas of neighboring agricultural zones.
In these regions, agricultural workers illegally set their fields on fire to clear them quickly, producing hazardous haze that then gets trapped over the metropolitan area as cooler air descends.
Public Health and Financial Consequences
Public health and economic consequences on the nearly 33 million inhabitants calling home the Delhi area is substantial, according to multiple research.
This pollution results in increased incidence of neurological, heart and circulatory and respiratory disorders, and can potentially cause malignancies.
Environmental contamination is projected to be causing ten thousand early fatalities per year in the capital.
