The megacity Awakens to Toxic Haze Post Diwali
On Tuesday morning citizens of the world's most polluted city found themselves breathing dangerously toxic air that registered in the "critical" level.
Alarming Pollution Levels
Multiple areas of Delhi registered an AQI over 500, which translates to ten times the healthy limit set by the World Health Organization.
In some locations, concentrations of toxic particulate matter soared to of eighteen hundred, amounting to fifteen to twenty times above safe standards.
Pyrotechnics Prohibition and New Changes
Since 2020, the government had enforced a comprehensive restriction on the distribution and bursting of firecrackers during Diwali due to their substantial impact to the hazardous pollution that covers the metropolis as colder weather approaches.
Yet in recent months, the current local administration appealed to the highest court to propose a relaxation of the prohibition.
Officials advocated for allowing "green crackers" – which have been doubted by environmentalists as being only roughly 30 percent lower impact – as a middle ground between "cultural practices and ecological concerns".
Judicial Decision and Implementation
To the disappointment of medical and ecological activists, judicial authorities approved the appeal, stipulating that eco-friendly pyrotechnics could be ignited during limited hours throughout the festival.
During the celebrations, there was considerable violation of the designated hours across the city, with insufficient monitoring regarding whether the firecrackers being used were actually the more environmentally friendly variety.
Numerous air quality sensors throughout Delhi registered air quality spiking around midnight to extremely hazardous readings seen during celebrations in at least recent memory.
Cross-Border Implications
Extensive ignition of pyrotechnics during the celebrations also initiated a controversy with neighbouring the neighboring country, with officials in Pakistan's Punjab province pointing to declining pollution levels in the city of Lahore on pollutants traveling from across the border following the celebrations.
Persistent Environmental Problem
Alarmingly severe levels of pollution in the capital have remained as a major issue for more than 15 years, with the situation gradually deteriorating.
Near the festival period, the levels of hazardous airborne contaminants in the atmosphere has been documented to spike to significantly exceeding the worst records ever measured in the Chinese city, which was once regarded as the world's most polluted city.
Diverse Pollution Factors
The situation in the capital is attributed to a convergence of various sources including heavy vehicle emissions, airborne particles, construction activities, waste incineration and pollutants from crop residue ignition in adjacent areas of farming communities.
In these regions, rural residents regularly set their fields on fire to prepare for next season, generating toxic pollution that then gets trapped over the city as colder air arrives.
Health and Economic Impact
Public health and economic toll on the approximately 33 million people living in the metropolitan zone is significant, according to various research.
This pollution leads to elevated rates of neurological, cardiovascular and respiratory diseases, and can result in oncological diseases.
Air quality crisis is estimated to be responsible for 10,000 untimely mortalities per year in the city.
