Delhi Rises to Toxic Haze After Celebrations

On Tuesday morning inhabitants of the world's most polluted city encountered exposed to extremely polluted air that was classified as the "critical" level.

Alarming Air Quality Levels

Various sections of Delhi recorded an pollution measurement above 500, which translates to 10x the safe level recommended by the WHO.

In some locations, concentrations of toxic particulate matter soared to of 1,800, equating to 15 to 20 times exceeding safe levels.

Firecracker Prohibition and Recent Changes

For the past four years, officials had enforced a comprehensive restriction on the purchase and ignition of fireworks during Diwali due to their significant contribution to the deadly pollution that engulfs the capital as colder weather approaches.

Yet earlier this year, the current local government appealed to the judicial authority to request a relaxation of the prohibition.

They proposed allowing "environmentally conscious pyrotechnics" – historically doubted by conservation groups as being only approximately one-third lower impact – as a middle ground between "tradition and environment".

Court Verdict and Enforcement

To the disappointment of environmental and health activists, the court complied with the appeal, specifying that green firecrackers could be set off during specific hours throughout the Diwali.

During the celebrations, there was extensive violation of the time restrictions across the capital, with insufficient regulation regarding whether the pyrotechnics being used were actually the eco-friendly type.

Many monitoring devices throughout Delhi registered air quality reaching highest levels around midnight to extremely hazardous readings observed during Diwali in at least three years.

Regional Consequences

The proliferation of fireworks during the celebrations also sparked a dispute with bordering Pakistan, with authorities in Pakistani Punjab partly blaming declining pollution levels in the city of Lahore on pollutants originating in across the border following the celebrations.

Persistent Pollution Problem

The dangerously high readings of atmospheric toxins in Delhi have continued as a serious problem for over a decade and a half, with the condition showing no improvement.

During the festival period, the levels of toxic airborne contaminants in the environment has been observed to increase dramatically to 70% higher the peak levels ever measured in the Chinese city, which was previously viewed as the planet's dirtiest urban center.

Diverse Contamination Sources

The situation in Delhi is resulting from a mix of multiple factors including heavy vehicle emissions, airborne particles, development work, waste incineration and pollutants from farm burning in nearby regions of neighboring agricultural zones.

In these regions, farmers illegally burn crop residue to prepare for next season, producing toxic haze that becomes contained over the city as colder air descends.

Public Health and Financial Impact

The economic and health toll on the approximately 33 million residents calling home the Delhi area is substantial, according to multiple research.

This pollution leads to elevated rates of nervous system, cardiovascular and lung conditions, and can even lead to cancer.

The pollution is estimated to be accounting for approximately 10k early deaths per year in Delhi.
