Delhi Awakens to Hazardous Pollution Post Diwali

Tuesday brought citizens of the planet's dirtiest urban center were faced with breathing severely hazardous air that registered in the "severe" range.

Extremely High Air Quality Readings

Multiple areas of the capital recorded an AQI exceeding 500, which represents 10x the recommended threshold recommended by the World Health Organization.

In some locations, levels of PM2.5 and PM10 hit highs of 1,800, equating to fifteen to twenty times higher than acceptable standards.

Pyrotechnics Ban and Current Policy Shifts

Beginning in 2020, authorities had implemented a complete ban on the purchase and ignition of fireworks during the Festival of Lights due to their significant contribution to the deadly smog that engulfs the capital as colder weather begins.

Nevertheless in recent months, the newly elected city administration petitioned the judicial authority to request a relaxation of the restrictions.

The suggestion was allowing "eco-friendly fireworks" – which have been doubted by conservation groups as being only about 30% reduced emissions – as a compromise between "tradition and environment".

Court Ruling and Enforcement

Despite concerns of environmental and health advocates, judges approved the request, specifying that environmentally conscious fireworks could be ignited during designated hours throughout the celebrations.

During the celebrations, there was widespread flouting of the regulated periods across the capital, with insufficient enforcement regarding whether the firecrackers being used were actually the eco-friendly type.

Numerous recording stations throughout the city registered pollution reaching highest levels around the night hours to some of the worst levels recorded during Diwali in at least three years.

Regional Implications

The widespread use of firecrackers during the celebrations also initiated a blame game with neighbouring the neighboring country, with representatives in Pakistani Punjab province partly blaming deteriorating air quality in their urban centers on contaminants originating in across the border following the festivities.

Long-Standing Pollution Issue

Alarmingly severe levels of air contamination in Delhi have continued as a significant problem for fifteen-plus years, with the condition gradually deteriorating.

Around Diwali, the amount of toxic particulate matter in the environment has been found to shoot up to significantly exceeding the peak levels ever measured in China's capital, which was formerly regarded as the world's most polluted metropolis.

Diverse Contamination Sources

The situation in Delhi is resulting from a mix of various sources including transportation pollution, construction debris, development work, waste incineration and haze from crop residue ignition in adjacent states of Punjab and Haryana.

Within these states, rural residents regularly ignite agricultural waste to clear them quickly, producing toxic pollution that remains stagnant over the capital as cooler air descends.

Health and Financial Impact

Both financial and medical toll on the nearly 33 million people residing in the Delhi area is significant, according to numerous research.

The contaminated air causes high levels of nervous system, cardiovascular and respiratory diseases, and can result in malignancies.

Air quality crisis is projected to be accounting for approximately 10k untimely deaths annually in the capital.
