HealthPhoto: MintDelhi Air Quality Drops to Very Poor Due to Farm Fire Smoke
Delhi's air quality index (AQI) worsened sharply from 117 on Saturday to 324 by Monday afternoon, reaching the "very poor" category for the first time this season. Analysis shows the primary cause is smoke from evening farm fires in Punjab and Haryana, not just weather conditions. PM2.5 levels on November 1 night averaged 194 micrograms per cubic metre, over three times the safe limit of 60.
