India's capital Awakens to Toxic Smog After Diwali

On Tuesday morning citizens of the world's most polluted city encountered inhaling extremely polluted air that was classified as the "critical" category.

Alarming Pollution Measurements

Various sections of the city showed an air quality index exceeding 500, which equals a tenfold increase over the recommended threshold recommended by the WHO.

Particular areas, readings of PM2.5 and PM10 hit highs of 1,800, amounting to 15-20x higher than healthy limits.

Fireworks Prohibition and New Developments

For the past four years, the government had implemented a complete ban on the distribution and bursting of pyrotechnics during celebrations due to their substantial impact to the hazardous haze that covers the capital as colder weather sets in.

Yet earlier this year, the current city government appealed to the highest court to seek a modification of the ban.

Officials advocated for allowing "environmentally conscious pyrotechnics" – previously doubted by conservation groups as being only approximately one-third less polluting – as a compromise between "heritage and environment".

Court Verdict and Enforcement

To the disappointment of medical and ecological advocates, the court approved the proposal, stipulating that environmentally conscious fireworks could be set off during designated time windows throughout the festival.

Throughout the festival evening, there was widespread violation of the designated hours across the capital, with little regulation regarding whether the fireworks being used were actually the eco-friendly variety.

Several recording stations throughout Delhi registered contamination peaking around the night hours to some of the worst measurements recorded during the festival in at least the past three years.

Cross-Border Effects

The proliferation of firecrackers during Diwali also sparked a controversy with neighbouring the neighboring country, with representatives in Pakistan's Punjab province partially attributing declining pollution levels in Lahore on contaminants traveling from India following the events.

Long-Standing Pollution Crisis

Extremely elevated readings of atmospheric toxins in the capital have remained as a major issue for more than 15 years, with the situation gradually deteriorating.

Near Diwali, the concentration of toxic particulate matter in the air has been documented to shoot up to seventy percent above the worst readings ever measured in Beijing, which was once considered as the world's most polluted metropolis.

Various Contamination Sources

The problem in Delhi is caused by a convergence of different contributors including automobile exhaust, airborne particles, development work, rubbish burning and haze from agricultural fires in neighbouring states of Punjab and Haryana.

In these regions, agricultural workers routinely set their fields on fire to expedite field preparation, creating dangerous smog that then gets trapped over the metropolitan area as cooler air sets in.

Health and Financial Impact

The economic and health impact on the roughly thirty-three million inhabitants living in the metropolitan zone is significant, according to various studies.

This pollution results in elevated rates of nervous system, cardiovascular and respiratory conditions, and can even lead to malignancies.

Environmental contamination is projected to be causing 10,000 premature fatalities per year in the city.
