Delhi records AQI above 400 in multiple areas on Diwali eve; health advisory issued as PM2.5 spikes, GRAP measures and crackle-ban urged to curb pollution.
Delhi’s air turned dangerously toxic on Diwali eve as multiple monitoring stations reported AQI readings in the severe category, with several pockets of the city crossing the 400 mark. City and central pollution monitors showed a sharp PM2.5 spike linked to calm winds, low temperature inversion and festival-related emissions. Authorities activated graded response actions (GRAP) and public health advisories urging residents — especially children, elderly and those with respiratory conditions — to limit outdoor exposure and use N95 masks when necessary.
Traffic curbs, bans on open burning and restrictions on dusty construction were among measures rolled out in the affected zones. Experts warned that fireworks and vehicle emissions can rapidly push local AQI from “very poor” into “severe,” elevating short-term cardiovascular and respiratory risks and exacerbating chronic illnesses. Short-term protective steps include using indoor air purifiers, avoiding outdoor exercise, sealing windows in the evening and seeking medical help for breathing difficulty.
