Delhi Wakes Under Thick Smog After Diwali Fireworks

New Delhi woke under thick smog after Diwali fireworks added another layer of pollution to an already troubled skyline. By 9 a.m. on November 9, the city’s official air-quality reading was 370, in India’s “very poor” category, while some neighborhoods exceeded 400 and reached “severe” levels, Reuters reported.

The gray aftermath of the festival of lights was visible around India Gate and across city streets. For residents, it meant another day breathing air affected by fireworks, traffic, construction and smoke drifting in from nearby farmland.

The air was polluted before the fireworks

Delhi had already endured poor air for more than a week, according to Reuters. Authorities imposed new restrictions November 6 under a graded response plan and asked schools to conduct online classes.

The November 9 reading of 370 compares with an official “good” range of up to 50. Readings vary across neighborhoods and monitoring times, so one citywide number does not capture everyone’s exposure.

Diwali celebrations added smoke and fine particles on Sunday evening. Residents told Reuters that firecrackers continued late into the night despite court-imposed limits. Reuters TV footage showed smog around India Gate, near government offices and Parliament, placing the visible effects in one of the capital’s most recognizable central locations.

For Isyad, a resident interviewed by the Associated Press, the effects were immediate. “Because of the pollution there is irritation in the throat and itching in the eyes,” he said.

Lower-emission fireworks still produce pollution

India’s Supreme Court had allowed only approved lower-polluting firecrackers during specified hours over the Diwali weekend. AP reporting carried by NPR described three-hour windows on Saturday and Sunday.

Those products release fewer emissions than conventional firecrackers, but they are not pollution-free. The smoke arrives during a season when the atmosphere is already less able to disperse it.

The festival itself is observed by millions through lights, family gatherings and other traditions. Fireworks are one part of the celebrations and one additional source in a much larger seasonal problem.

Photographs showed familiar landmarks fading behind haze. The air-quality readings add information the images cannot: the problem was being measured across the city, not simply captured in one dramatic view.

Farm fires and winter weather add to the burden

After the rice harvest, farmers in Punjab and Haryana sometimes burn leftover stalks to prepare for the next planting season. Smoke can drift toward the capital and combine with local emissions.

Vehicles, industrial activity and construction dust contribute throughout the region. The timing becomes especially difficult in late October and November, when temperatures fall, winds weaken and stagnant air keeps pollutants from dispersing.

New Delhi and its metropolitan area are home to more than 30 million people, AP reported. That wider region extends beyond the city itself, which is why efforts to reduce pollution also involve neighboring jurisdictions.

The sources do not stop when the holiday ends. Fireworks intensify the episode, but traffic and industrial emissions continue, while weather determines how quickly accumulated pollution moves away.

Short-term restrictions meet a year-round problem

Authorities have limited construction activity and diesel generators as part of their response. These measures target particular emissions, but severe seasonal episodes have continued to return.

The disruption also reaches classrooms and daily routines. Reuters’ report of online-class instructions shows that the response is not limited to warnings about distant environmental damage; it changes how children attend school during the episode.

For people earning a living outside, including street vendors and construction workers, reducing time outdoors can be harder. Children, older residents and people with respiratory conditions face particular concerns during polluted conditions.

Public-health expert Shweta Narayan of the Global Climate and Health Alliance told AP that the response remained temporary and reactive. Environmental specialists called for cleaner energy and stronger vehicle-emission controls - measures aimed at the sources that will remain after the last firecracker has burned out.
