The megacity Rises to Hazardous Pollution Following Celebrations

Tuesday brought inhabitants of the planet's dirtiest urban center were faced with breathing severely hazardous air that was classified as the "critical" range.

Record-Breaking Air Quality Measurements

Several parts of the city showed an air quality index above 500, which represents 10x the safe level recommended by the WHO.

Certain monitoring stations, readings of dangerous airborne particles hit highs of eighteen hundred, representing fifteen to twenty times higher than safe levels.

Fireworks Restrictions and Recent Policy Shifts

For the past four years, authorities had implemented a complete ban on the sale and use of pyrotechnics during the Festival of Lights due to their major role to the hazardous pollution that engulfs the capital as winter sets in.

However in recent months, the current local government petitioned the supreme court to propose a modification of the restrictions.

They proposed allowing "eco-friendly fireworks" – previously doubted by environmentalists as being only about 30% reduced emissions – as a balance between "heritage and environment".

Legal Decision and Implementation

Despite concerns of environmental and health campaigners, judicial authorities agreed to the request, stipulating that green firecrackers could be ignited during designated periods throughout the Diwali.

Throughout the festival evening, there was extensive disregard of the time restrictions across the capital, with minimal regulation regarding whether the firecrackers being used were actually the more environmentally friendly variety.

Many monitoring devices throughout Delhi registered pollution spiking around midnight to the most severe levels recorded during the festival in at least recent memory.

Regional Implications

The widespread use of fireworks during the festival also initiated a blame game with neighbouring the neighboring country, with representatives in Pakistani Punjab partially attributing declining pollution levels in the city of Lahore on hazardous particles originating in across the border following the celebrations.

Persistent Environmental Problem

Extremely elevated levels of pollution in Delhi have remained as a serious problem for fifteen-plus years, with the condition showing no improvement.

Around Diwali, the levels of hazardous particulate matter in the atmosphere has been documented to shoot up to significantly exceeding the worst readings ever recorded in Beijing, which was once viewed as the world's most polluted urban center.

Various Pollution Contributors

The problem in the capital is attributed to a combination of various sources including transportation pollution, construction debris, development work, rubbish burning and pollutants from agricultural fires in neighbouring areas of neighboring agricultural zones.

Within these states, rural residents regularly ignite agricultural waste to prepare for next season, creating hazardous pollution that remains stagnant over the metropolitan area as winter air arrives.
