HealthPhoto: Hindustan TimesFarm Fires in Punjab and Haryana Cause Delhi's Smog Surge
Smoke from farm fires in Punjab and Haryana caused a sharp rise in Delhi's pollution, pushing air quality into the 'very poor' range on Monday. Fires were mostly lit after NASA's satellite passed, which tracks stubble burning. Delhi's air quality index rose from 117 on Saturday to 324 by Monday afternoon, marking the season's first very poor reading amid still weather and low wind.
