The megacity Rises to Dangerous Haze Following Diwali

As Tuesday dawned residents of the planet's dirtiest urban center encountered inhaling extremely polluted air that registered in the "alarming" level.

Extremely High Pollution Readings

Multiple areas of Delhi showed an AQI exceeding 500, which translates to 10x the recommended threshold recommended by the global health authority.

In some locations, concentrations of toxic particulate matter hit highs of 1,800, representing 15-20x above acceptable limits.

Pyrotechnics Prohibition and Current Developments

Since 2020, the government had enforced a total prohibition on the sale and use of pyrotechnics during celebrations due to their major role to the dangerous smog that engulfs the city as winter sets in.

Nevertheless recently, the newly elected local government petitioned the judicial authority to propose a relaxation of the ban.

Officials advocated for allowing "green crackers" – previously questioned by environmentalists as being only about 30% reduced emissions – as a compromise between "tradition and public health".

Judicial Decision and Reality

Despite concerns of environmental and health activists, judicial authorities agreed to the request, specifying that environmentally conscious fireworks could be used during specific time windows throughout the festival.

On Monday night, there was considerable flouting of the designated hours across the city, with insufficient regulation regarding whether the fireworks being used were actually the supposedly greener version.

Several air quality sensors throughout the city showed air quality spiking around the night hours to extremely hazardous levels recorded during Diwali in at least three years.

Regional Effects

Extensive ignition of pyrotechnics during the celebrations also sparked a blame game with bordering Pakistan, with officials in Pakistani Punjab province partly blaming worsening pollution levels in their urban centers on contaminants coming from India following the festivities.

Persistent Environmental Crisis

The dangerously high levels of pollution in Delhi have continued as a major issue for fifteen-plus years, with the situation gradually deteriorating.

Around Diwali, the levels of dangerous particles in the air has been observed to increase dramatically to 70% higher the peak levels ever documented in Beijing, which was once viewed as the world's most polluted urban center.

Various Pollution Factors

The situation in Delhi is caused by a convergence of various sources including heavy vehicle emissions, construction debris, construction activities, waste incineration and smoke from agricultural fires in neighbouring states of Punjab and Haryana.

Within these states, agricultural workers routinely ignite agricultural waste to prepare for next season, creating hazardous smog that becomes contained over the capital as winter air arrives.

Health and Economic Impact

The economic and health toll on the nearly 33 million inhabitants residing in the metropolitan zone is enormous, according to multiple research.

This pollution causes elevated rates of neurological, cardiovascular and respiratory diseases, and can potentially cause oncological diseases.

The pollution is projected to be accounting for ten thousand premature mortalities each year in the city.
