Delhi Awakens to Hazardous Haze After Diwali

As Tuesday dawned residents of this heavily contaminated metropolis encountered inhaling dangerously toxic air that registered in the "severe" range.

Extremely High Air Quality Readings

Several parts of the city recorded an pollution measurement above 500, which represents a tenfold increase over the safe limit recommended by the global health authority.

Certain monitoring stations, readings of dangerous airborne particles reached peaks of 1800, amounting to 15 to 20 times above safe limits.

Firecracker Ban and Current Developments

Since 2020, the government had implemented a total prohibition on the sale and use of firecrackers during the Festival of Lights due to their significant contribution to the hazardous pollution that covers the capital as winter sets in.

However in recent months, the current city government appealed to the highest court to seek a modification of the prohibition.

The suggestion was allowing "green crackers" – historically criticized by conservation groups as being only approximately one-third less polluting – as a compromise between "tradition and environment".

Legal Ruling and Implementation

Despite concerns of medical and ecological activists, the court complied with the proposal, specifying that green firecrackers could be ignited during specific time windows throughout the celebrations.

During the celebrations, there was considerable violation of the regulated periods across the city, with little enforcement regarding whether the firecrackers being used were actually the eco-friendly variety.

Several monitoring devices throughout Delhi registered air quality spiking around the night hours to some of the worst measurements observed during the festival in at least the past three years.

Regional Consequences

The proliferation of firecrackers during Diwali also triggered a controversy with adjacent Pakistan, with authorities in Pakistan's Punjab province partly blaming deteriorating pollution levels in their urban centers on contaminants originating in neighboring India following the celebrations.

Long-Standing Environmental Issue

Extremely elevated concentrations of pollution in the city have remained as a major issue for fifteen-plus years, with the condition gradually deteriorating.

Near celebratory seasons, the levels of hazardous airborne contaminants in the air has been found to spike to significantly exceeding the most severe records ever measured in the Chinese city, which was once viewed as the world's most polluted metropolis.

Various Pollution Sources

The situation in Delhi is resulting from a convergence of various sources including automobile exhaust, construction debris, building projects, garbage fires and pollutants from farm burning in neighbouring states of farming communities.

In these regions, rural residents illegally burn crop residue to expedite field preparation, creating toxic haze that then gets trapped over the city as colder air sets in.

Public Health and Economic Consequences

The economic and health consequences on the approximately 33 million residents living in the metropolitan zone is substantial, according to multiple investigations.

These hazardous conditions results in high levels of nervous system, cardiovascular and breathing diseases, and can result in cancer.

Environmental contamination is calculated to be responsible for 10,000 untimely mortalities annually in Delhi.
