Delhi Sees Worst Diwali Air Pollution in Five Years, AQI Stations Offline

Delhi experienced its most severe air pollution during Diwali, with particulate matter levels spiking to alarming levels across the city. The spike is attributed to widespread fireworks and vehicular emissions that accompany the festival. Several air quality monitoring stations failed to report AQI data, raising concerns about the reliability of real‑time pollution metrics.

Environmental officials have urged residents to limit outdoor activities and to use protective masks. The government has also announced plans to activate additional monitoring sites and to enforce stricter emission controls on fireworks vendors.

Health experts warn that prolonged exposure to such high pollution can exacerbate respiratory and cardiovascular conditions, especially among vulnerable groups. Citizens are advised to stay indoors during peak hours and to keep windows closed.
