The megacity Rises to Dangerous Pollution Following Diwali

As Tuesday dawned citizens of this heavily contaminated metropolis encountered breathing extremely polluted air that was classified as the "alarming" level.

Alarming Pollution Levels

Various sections of Delhi recorded an air quality index exceeding 500, which translates to a tenfold increase over the healthy limit set by the WHO.

Certain monitoring stations, readings of toxic particulate matter hit highs of 1800, equating to 15-20x exceeding safe limits.

Fireworks Ban and Current Developments

Since 2020, officials had maintained a complete ban on the distribution and bursting of pyrotechnics during Diwali due to their major role to the hazardous haze that engulfs the capital as the cold season begins.

However earlier this year, the recently formed regional leadership petitioned the judicial authority to propose a relaxation of the restrictions.

They proposed allowing "green crackers" – historically criticized by environmentalists as being only approximately one-third less polluting – as a compromise between "heritage and public health".

Judicial Ruling and Enforcement

Despite concerns of environmental and health campaigners, judicial authorities agreed to the request, stipulating that eco-friendly pyrotechnics could be set off during limited time windows throughout the festival.

On Monday night, there was extensive violation of the regulated periods across the city, with minimal regulation regarding whether the firecrackers being used were actually the supposedly greener version.

Several air quality sensors throughout the capital recorded air quality peaking around the night hours to extremely hazardous levels recorded during Diwali in at least the past three years.

International Implications

The proliferation of pyrotechnics during the celebrations also initiated a blame game with adjacent the neighboring country, with representatives in Pakistan's Punjab partially attributing worsening air quality in their urban centers on pollutants coming from neighboring India following the festivities.

Long-Standing Environmental Problem

The dangerously high concentrations of pollution in Delhi have remained as a major challenge for fifteen-plus years, with the situation gradually deteriorating.

Around the festival period, the amount of dangerous particulate matter in the air has been found to spike to 70% higher the worst records ever measured in the Chinese city, which was formerly viewed as the planet's dirtiest city.

Various Contamination Contributors

This crisis in the city is resulting from a combination of multiple factors including automobile exhaust, dust, construction activities, rubbish burning and pollutants from agricultural fires in nearby states of farming communities.

In these regions, agricultural workers routinely ignite agricultural waste to expedite field preparation, generating toxic pollution that then gets trapped over the capital as winter air arrives.

Health and Economic Toll

Public health and economic toll on the approximately 33 million residents calling home the Delhi area is enormous, according to various investigations.

This pollution leads to elevated rates of neurological, cardiovascular and lung disorders, and can even lead to malignancies.

Environmental contamination is calculated to be causing approximately 10k early fatalities annually in Delhi.
