The megacity Rises to Hazardous Pollution Post Festival of Lights
On Tuesday morning residents of the planet's dirtiest urban center encountered breathing severely hazardous air that fell into the "severe" range.
Extremely High Pollution Levels
Several parts of the capital recorded an air quality index over 500, which equals a tenfold increase over the safe limit set by the global health authority.
In some locations, readings of dangerous airborne particles soared to of 1800, amounting to 15 to 20 times exceeding safe limits.
Firecracker Prohibition and Recent Changes
Beginning in 2020, authorities had maintained a total prohibition on the distribution and bursting of firecrackers during celebrations due to their major role to the dangerous pollution that covers the city as winter sets in.
Yet in recent months, the recently formed city administration appealed to the supreme court to request a easing of the ban.
They proposed allowing "green crackers" – which have been criticized by environmental experts as being only roughly 30 percent less polluting – as a middle ground between "tradition and environment".
Judicial Decision and Reality
Despite concerns of medical and ecological advocates, the court complied with the proposal, stipulating that eco-friendly pyrotechnics could be set off during limited periods throughout the celebrations.
On Monday night, there was considerable flouting of the regulated periods across the metropolis, with insufficient enforcement regarding whether the firecrackers being used were actually the supposedly greener type.
Several monitoring devices throughout Delhi recorded air quality reaching highest levels around late evening to the most severe levels recorded during the festival in at least the past three years.
International Effects
The widespread use of pyrotechnics during the celebrations also sparked a controversy with neighbouring the neighboring country, with officials in Pakistani Punjab province partly blaming declining air quality in Lahore on pollutants traveling from across the border following the events.
Long-Standing Environmental Crisis
The dangerously high readings of air contamination in the city have remained as a major challenge for over a decade and a half, with the problem continuing to worsen.
Around celebratory seasons, the levels of hazardous particles in the air has been documented to increase dramatically to significantly exceeding the most severe levels ever recorded in Beijing, which was once viewed as the planet's dirtiest city.
Multiple Contamination Contributors
This crisis in the capital is attributed to a convergence of different contributors including automobile exhaust, airborne particles, development work, garbage fires and haze from agricultural fires in nearby states of Punjab and Haryana.
Within these states, farmers routinely burn crop residue to prepare for next season, generating hazardous smog that then gets trapped over the capital as colder air arrives.
Health and Financial Impact
The economic and health impact on the approximately 33 million residents calling home the Delhi area is substantial, according to multiple investigations.
The contaminated air causes high levels of neurological, heart and circulatory and respiratory conditions, and can even lead to oncological diseases.
The pollution is estimated to be accounting for 10,000 premature mortalities per year in Delhi.
