The megacity Wakes Up to Toxic Haze Post Festival of Lights
On Tuesday morning inhabitants of the world's most polluted city found themselves inhaling dangerously toxic air that registered in the "alarming" level.
Record-Breaking Air Quality Levels
Various sections of the capital showed an pollution measurement above 500, which equals 10x the recommended limit recommended by the World Health Organization.
Certain monitoring stations, concentrations of dangerous airborne particles hit highs of 1,800, equating to 15-20x higher than healthy levels.
Pyrotechnics Restrictions and Recent Policy Shifts
Beginning in 2020, authorities had enforced a total prohibition on the sale and use of firecrackers during the Festival of Lights due to their significant contribution to the dangerous pollution that engulfs the city as colder weather sets in.
Nevertheless in recent months, the current local leadership appealed to the highest court to propose a modification of the prohibition.
The suggestion was allowing "eco-friendly fireworks" – which have been questioned by conservation groups as being only about 30% reduced emissions – as a balance between "heritage and ecological concerns".
Judicial Decision and Reality
To the disappointment of medical and ecological advocates, the court approved the request, stipulating that environmentally conscious fireworks could be ignited during limited periods throughout the Diwali.
On Monday night, there was considerable violation of the regulated periods across the capital, with insufficient enforcement regarding whether the firecrackers being used were actually the eco-friendly variety.
Several monitoring devices throughout Delhi showed pollution reaching highest levels around late evening to extremely hazardous readings observed during celebrations in at least recent memory.
International Effects
The widespread use of pyrotechnics during the festival also initiated a dispute with bordering Pakistan, with representatives in Pakistani Punjab partially attributing deteriorating air quality in the city of Lahore on pollutants traveling from India following the events.
Long-Standing Pollution Crisis
Alarmingly severe readings of air contamination in Delhi have remained as a significant issue for more than 15 years, with the problem showing no improvement.
Around Diwali, the levels of dangerous airborne contaminants in the air has been observed to shoot up to 70% higher the worst levels ever measured in Beijing, which was once viewed as the world's most polluted urban center.
Diverse Contamination Contributors
The problem in Delhi is caused by a mix of various sources including automobile exhaust, construction debris, construction activities, waste incineration and smoke from agricultural fires in adjacent regions of Punjab and Haryana.
Within these states, agricultural workers routinely burn crop residue to expedite field preparation, generating hazardous pollution that then gets trapped over the metropolitan area as cooler air sets in.
Medical and Economic Toll
Both financial and medical toll on the nearly 33 million people calling home the metropolitan zone is enormous, according to various investigations.
This pollution leads to elevated rates of nervous system, heart and circulatory and respiratory diseases, and can potentially cause malignancies.
The pollution is estimated to be responsible for ten thousand early fatalities each year in Delhi.
