India's capital Awakens to Hazardous Haze After Diwali

On Tuesday morning inhabitants of the planet's dirtiest urban center found themselves breathing extremely polluted air that registered in the "severe" range.

Extremely High Air Quality Readings

Various sections of Delhi registered an air quality index over 500, which translates to 10x the safe threshold set by the WHO.

Certain monitoring stations, concentrations of PM2.5 and PM10 soared to of 1800, amounting to 15 to 20 times above healthy standards.

Pyrotechnics Prohibition and New Developments

For the past four years, authorities had maintained a comprehensive restriction on the sale and use of pyrotechnics during celebrations due to their major role to the hazardous pollution that engulfs the capital as winter sets in.

Nevertheless earlier this year, the recently formed city administration appealed to the judicial authority to seek a modification of the ban.

Officials advocated for allowing "eco-friendly fireworks" – previously doubted by environmental experts as being only roughly 30 percent lower impact – as a compromise between "heritage and ecological concerns".

Judicial Decision and Enforcement

Despite concerns of public health and environmental advocates, judicial authorities complied with the appeal, stipulating that green firecrackers could be set off during specific hours throughout the celebrations.

Throughout the festival evening, there was extensive flouting of the designated hours across the capital, with little regulation regarding whether the firecrackers being used were actually the more environmentally friendly version.

Numerous monitoring devices throughout Delhi registered pollution spiking around the night hours to extremely hazardous levels seen during Diwali in at least recent memory.

Cross-Border Implications

The widespread use of fireworks during the festival also triggered a blame game with adjacent the neighboring country, with authorities in Pakistani Punjab province pointing to worsening air quality in their urban centers on hazardous particles traveling from India following the events.

Chronic Pollution Issue

Alarmingly severe levels of pollution in the capital have remained as a major issue for more than 15 years, with the situation gradually deteriorating.

Around the festival period, the amount of toxic particles in the air has been observed to increase dramatically to seventy percent above the peak readings ever measured in Beijing, which was previously viewed as the globally most contaminated urban center.

Multiple Contamination Sources

This crisis in Delhi is caused by a combination of multiple factors including transportation pollution, dust, development work, rubbish burning and pollutants from crop residue ignition in adjacent regions of Punjab and Haryana.

In these regions, agricultural workers routinely set their fields on fire to prepare for next season, producing hazardous pollution that becomes contained over the metropolitan area as cooler air arrives.

Medical and Financial Consequences

The economic and health impact on the approximately 33 million inhabitants residing in the capital region is significant, according to various research.

This pollution leads to high levels of nervous system, heart and circulatory and breathing conditions, and can result in malignancies.

The pollution is estimated to be responsible for approximately 10k untimely mortalities each year in Delhi.
