Delhi chokes: AQI 324, plunges to ‘very poor’; Stage-II GRAP invoked

The Capital’s air quality index climbed dramatically over a two‑day period, moving from a moderate rating of 117 on October 31 to a very poor level of 324 on November 1, according to data released by the Central Pollution Control Board. This rapid rise triggered the activation of Stage‑II measures under the Graded Response Action Plan, a protocol that requires additional restrictions on industrial activity, construction work, and vehicular movement. The GRAP sub‑committee highlighted that the spike was driven by a combination of stagnant weather conditions and increased emissions from traffic and small‑scale industries.

Health officials warned that the deteriorating air could exacerbate respiratory problems, especially for children, the elderly, and those with pre‑existing conditions. Hospitals in the city reported a noticeable uptick in patients seeking treatment for asthma and other breathing difficulties. The board advised residents to limit outdoor activities, use masks that filter fine particles, and keep windows closed during peak pollution hours. Schools were urged to consider temporary closures or shift to online classes if the air quality does not improve within the next 24‑48 hours.

The episode adds to a pattern of seasonal air‑quality challenges that Delhi faces each winter, prompting calls for longer‑term solutions such as expanding green cover, improving public transport, and enforcing stricter emission standards for vehicles and factories. For citizens, the immediate concern is personal safety, while policymakers will need to balance economic activity with public health priorities. The next few days will reveal whether the emergency measures can bring the index back to safer levels.
