On Tuesday morning inhabitants of the world's most polluted city were faced with inhaling extremely polluted air that fell into the "critical" category.

Extremely High Pollution Measurements

Several parts of the city showed an air quality index over 500, which translates to ten times the recommended limit set by the World Health Organization.

Particular areas, concentrations of dangerous airborne particles soared to of eighteen hundred, equating to 15 to 20 times higher than safe standards.

Pyrotechnics Ban and New Changes

Beginning in 2020, authorities had enforced a comprehensive restriction on the distribution and bursting of firecrackers during Diwali due to their substantial impact to the deadly haze that blankets the metropolis as colder weather begins.

However recently, the recently formed regional leadership approached the judicial authority to seek a modification of the prohibition.

The suggestion was allowing "environmentally conscious pyrotechnics" – historically doubted by environmentalists as being only about 30% reduced emissions – as a balance between "cultural practices and public health".

Court Verdict and Enforcement

Much to the frustration of environmental and health campaigners, judicial authorities approved the request, stipulating that green firecrackers could be used during specific time windows throughout the celebrations.

During the celebrations, there was considerable violation of the regulated periods across the capital, with little regulation regarding whether the pyrotechnics being used were actually the supposedly greener variety.

Many recording stations throughout the capital registered contamination reaching highest levels around midnight to some of the worst levels recorded during celebrations in at least three years.

Cross-Border Effects

The widespread use of firecrackers during Diwali also initiated a dispute with adjacent Pakistan, with representatives in Pakistan's Punjab province pointing to worsening atmospheric conditions in their urban centers on hazardous particles coming from India following the celebrations.

Long-Standing Pollution Issue

Extremely elevated readings of atmospheric toxins in the city have remained as a serious problem for fifteen-plus years, with the condition showing no improvement.

Around celebratory seasons, the concentration of dangerous particulate matter in the atmosphere has been observed to shoot up to significantly exceeding the worst records ever documented in Beijing, which was previously regarded as the globally most contaminated urban center.

Diverse Pollution Factors

This crisis in the city is caused by a mix of different contributors including heavy vehicle emissions, dust, development work, rubbish burning and haze from agricultural fires in neighbouring regions of Punjab and Haryana.

Throughout these areas, agricultural workers regularly set their fields on fire to clear them quickly, producing dangerous haze that then gets trapped over the metropolitan area as winter air descends.

Medical and Economic Toll

Both financial and medical toll on the roughly thirty-three million people residing in the metropolitan zone is substantial, according to various studies.

These hazardous conditions leads to elevated rates of nervous system, heart and circulatory and breathing conditions, and can even lead to malignancies.

Air quality crisis is calculated to be responsible for 10,000 premature mortalities per year in the capital.
