The megacity Rises to Dangerous Haze Post Festival of Lights

Tuesday brought inhabitants of the world's most polluted city were faced with exposed to extremely polluted air that registered in the "alarming" range.

Record-Breaking Pollution Levels

Various sections of the capital showed an AQI over 500, which equals a tenfold increase over the healthy limit set by the World Health Organization.

Particular areas, concentrations of dangerous airborne particles hit highs of 1,800, amounting to 15-20x exceeding acceptable levels.

Firecracker Prohibition and New Policy Shifts

Beginning in 2020, the government had implemented a total prohibition on the purchase and ignition of fireworks during Diwali due to their significant contribution to the deadly haze that covers the city as winter sets in.

Yet earlier this year, the newly elected city administration appealed to the supreme court to propose a modification of the ban.

They proposed allowing "environmentally conscious pyrotechnics" – which have been doubted by environmentalists as being only about 30% less polluting – as a balance between "cultural practices and public health".

Judicial Ruling and Reality

Much to the frustration of environmental and health campaigners, judges complied with the proposal, stipulating that environmentally conscious fireworks could be used during designated hours throughout the festival.

On Monday night, there was considerable violation of the designated hours across the city, with little monitoring regarding whether the pyrotechnics being used were actually the more environmentally friendly version.

Numerous air quality sensors throughout Delhi recorded contamination reaching highest levels around midnight to some of the worst readings observed during celebrations in at least recent memory.

Cross-Border Consequences

The widespread use of fireworks during the celebrations also sparked a controversy with neighbouring the neighboring country, with authorities in Pakistani the Punjab region pointing to deteriorating atmospheric conditions in the city of Lahore on pollutants traveling from India following the festivities.

Chronic Environmental Issue

Alarmingly severe readings of air contamination in the capital have continued as a major challenge for more than 15 years, with the problem continuing to worsen.

During the festival period, the amount of toxic particles in the environment has been found to shoot up to seventy percent above the most severe readings ever measured in Beijing, which was formerly viewed as the globally most contaminated metropolis.

Various Pollution Sources

The situation in the city is caused by a mix of multiple factors including transportation pollution, dust, building projects, garbage fires and haze from agricultural fires in adjacent regions of farming communities.

Within these states, agricultural workers regularly ignite agricultural waste to clear them quickly, producing hazardous haze that remains stagnant over the metropolitan area as winter air descends.

Health and Economic Consequences

Both financial and medical toll on the nearly 33 million inhabitants residing in the metropolitan zone is enormous, according to numerous studies.

These hazardous conditions results in high levels of nervous system, heart and circulatory and lung disorders, and can result in malignancies.

Environmental contamination is estimated to be accounting for ten thousand untimely deaths annually in the capital.
