On Tuesday morning citizens of the world's most polluted city were faced with inhaling dangerously toxic air that was classified as the "severe" level.

Extremely High Pollution Measurements

Various sections of Delhi registered an AQI over 500, which represents ten times the safe limit set by the WHO.

In some locations, readings of dangerous airborne particles soared to of 1,800, amounting to 15-20x exceeding acceptable levels.

Fireworks Prohibition and Recent Changes

Beginning in 2020, officials had maintained a comprehensive restriction on the purchase and ignition of pyrotechnics during celebrations due to their significant contribution to the deadly haze that blankets the city as the cold season sets in.

Yet recently, the recently formed local government petitioned the judicial authority to propose a relaxation of the restrictions.

Officials advocated for allowing "eco-friendly fireworks" – previously doubted by environmentalists as being only about 30% less polluting – as a balance between "tradition and ecological concerns".

Legal Decision and Enforcement

Much to the frustration of medical and ecological campaigners, the court complied with the proposal, stipulating that environmentally conscious fireworks could be used during limited time windows throughout the celebrations.

During the celebrations, there was extensive violation of the designated hours across the metropolis, with minimal regulation regarding whether the fireworks being used were actually the eco-friendly type.

Many recording stations throughout the capital recorded contamination peaking around the night hours to some of the worst levels recorded during the festival in at least three years.

Regional Consequences

The widespread use of fireworks during the celebrations also initiated a blame game with adjacent the neighboring country, with representatives in Pakistani the Punjab region partially attributing deteriorating air quality in their urban centers on contaminants traveling from neighboring India following the events.

Persistent Pollution Issue

The dangerously high concentrations of atmospheric toxins in Delhi have continued as a major problem for over a decade and a half, with the problem continuing to worsen.

Around Diwali, the concentration of hazardous particles in the environment has been found to shoot up to 70% higher the peak records ever measured in Beijing, which was once viewed as the globally most contaminated city.

Multiple Pollution Sources

The problem in Delhi is resulting from a mix of different contributors including transportation pollution, airborne particles, development work, waste incineration and pollutants from farm burning in adjacent states of neighboring agricultural zones.

Within these states, rural residents regularly set their fields on fire to prepare for next season, producing dangerous smog that then gets trapped over the metropolitan area as winter air sets in.

Health and Financial Consequences

Public health and economic consequences on the roughly thirty-three million people residing in the Delhi area is significant, according to multiple research.

These hazardous conditions causes increased incidence of neurological, heart and circulatory and lung conditions, and can result in malignancies.

The pollution is calculated to be responsible for 10,000 premature fatalities annually in the city.
