The capital’s air‑quality index jumped from a moderate 124 to a hazardous level above 400 in just four days, prompting urgent alerts.
Delhi’s air‑quality index (AQI) climbed sharply from 124 to more than 400 in a span of 96 hours, moving the city into the hazardous pollution bracket. The rapid escalation was recorded over three consecutive days, pushing the AQI beyond the threshold that health officials consider dangerous for the general public.
Health agencies have issued advisories urging residents to limit outdoor activities, especially those with respiratory conditions, and to use masks when venturing outside. Schools and workplaces in heavily affected zones have been advised to monitor indoor air quality and consider remote arrangements where feasible.
City officials confirmed that monitoring stations across Delhi captured the spike and that a detailed investigation is underway to identify the drivers behind the sudden deterioration. While the exact causes remain under review, authorities have pledged to keep the public informed and to take corrective measures as soon as actionable data become available.
The unprecedented rise in AQI underscores the city's ongoing struggle with air‑pollution challenges, prompting renewed calls for stricter emission controls and coordinated regional efforts to improve air quality.
