A thick blanket of smog has engulfed India's capital, New Delhi, following Diwali celebrations that saw widespread use of firecrackers. Despite restrictions on fireworks, residents lit up the skies on Sunday evening, releasing smoke and fine particulate matter into the atmosphere. This has compounded the city's dangerously high pollution levels, intensifying the seasonal air pollution crisis that grips New Delhi every year.
The air quality index in several parts of the capital exceeded 350 on Monday morning, reaching the severe category and posing significant health risks. Monitoring stations across the city recorded similarly alarming levels, while visibility deteriorated as a gray haze blanketed streets and high-rise buildings. The Supreme Court had sought to limit Diwali pollution by restricting conventional firecrackers and allowing only approved "green firecrackers" under specified conditions.
However, even the approved green firecrackers produce fewer emissions but are not pollution-free, still releasing particulate matter and other pollutants. This adds to the city's already hazardous air, taking a toll on residents' health. Isyad, a New Delhi resident, said the worsening smog was causing irritation in his throat and itching in his eyes.
New Delhi and its metropolitan region, home to over 30 million people, regularly rank among the world's most polluted areas during winter. The problem worsens as Diwali fireworks coincide with cooler weather and smoke from crop-residue fires in neighboring states of Punjab and Haryana. Farmers often burn leftover stalks to clear their fields for the next planting season, and the smoke drifts toward New Delhi.
The city's pollution crisis becomes particularly acute in late October and November, when cooler temperatures, low wind speeds, and stagnant atmospheric conditions prevent pollutants from dispersing. The result is a thick haze that can linger over the capital and surrounding areas for days. Authorities have implemented measures to curb pollution, including limits on construction activity and restrictions on diesel generators.
Environmentalists say long-term solutions, such as cleaner energy and stricter controls on vehicle emissions, are needed to prevent the annual crisis. Shweta Narayan, a public health expert at the Global Climate and Health Alliance, described the government's response so far as "knee-jerk" and "temporary." She believes that more sustained efforts are required to address the root causes of the pollution.
The annual pollution crisis in New Delhi highlights the need for a comprehensive approach to address the city's environmental challenges. While short-term measures may provide temporary relief, the city's residents and authorities must work together to develop and implement effective long-term solutions to mitigate the effects of pollution and ensure a healthier future for its citizens.
