Delhi Awakens to Toxic Haze Post Diwali

Tuesday brought inhabitants of this heavily contaminated metropolis encountered breathing severely hazardous air that fell into the "alarming" category.

Extremely High Air Quality Measurements

Various sections of the capital registered an pollution measurement over 500, which equals a tenfold increase over the healthy threshold established by the WHO.

Certain monitoring stations, concentrations of toxic particulate matter hit highs of 1800, amounting to 15 to 20 times higher than acceptable standards.

Pyrotechnics Ban and Recent Developments

Beginning in 2020, authorities had enforced a comprehensive restriction on the distribution and bursting of fireworks during Diwali due to their substantial impact to the deadly pollution that covers the city as colder weather begins.

Yet recently, the current regional administration petitioned the supreme court to request a easing of the ban.

They proposed allowing "eco-friendly fireworks" – which have been doubted by conservation groups as being only about 30% lower impact – as a middle ground between "tradition and ecological concerns".

Legal Verdict and Implementation

Despite concerns of environmental and health activists, the court approved the request, mandating that eco-friendly pyrotechnics could be used during designated time windows throughout the festival.

Throughout the festival evening, there was widespread violation of the designated hours across the city, with insufficient enforcement regarding whether the fireworks being used were actually the more environmentally friendly variety.

Numerous monitoring devices throughout the capital registered contamination reaching highest levels around late evening to extremely hazardous levels seen during celebrations in at least three years.

Regional Implications

Extensive ignition of pyrotechnics during the celebrations also triggered a dispute with adjacent Pakistan, with authorities in Pakistani the Punjab region pointing to worsening atmospheric conditions in Lahore on pollutants coming from neighboring India following the festivities.

Chronic Pollution Issue

The dangerously high readings of air contamination in Delhi have continued as a serious issue for more than 15 years, with the problem gradually deteriorating.

Near Diwali, the levels of dangerous particles in the atmosphere has been observed to shoot up to 70% higher the worst records ever recorded in Beijing, which was once regarded as the planet's dirtiest city.

Multiple Contamination Factors

The problem in the capital is resulting from a mix of different contributors including heavy vehicle emissions, dust, development work, waste incineration and smoke from farm burning in neighbouring regions of farming communities.

Within these states, farmers routinely ignite agricultural waste to clear them quickly, creating toxic haze that becomes contained over the city as colder air descends.

Public Health and Economic Toll

Both financial and medical toll on the approximately 33 million residents living in the Delhi area is enormous, according to various studies.

The contaminated air results in increased incidence of nervous system, heart and circulatory and lung diseases, and can result in malignancies.

The pollution is projected to be accounting for ten thousand early fatalities each year in the capital.
