Traffic, not stubble, behind daily pollution spikes in Delhi: Study
Even with farm fires at a multi-year low, Delhi-NCR's winter air remains suffocating. For most of October and November, pollution levels hovered between 'very poor' and 'severe', fuelled by a rising "toxic cocktail" of PM2.5, nitrogen dioxide (NO₂) and carbon monoxide (CO) emitted mainly from vehicles and other local sources. At least 22 air-quality monitoring stations in Delhi recorded carbon monoxide (CO) levels above permissible limits on more than 30 of the 59 days assessed, with Dwarka Sector 8 logging the highest number of breaches at 55 days, followed by Jahangirpuri and Delhi University's North Campus, both at 50 days, according to a new analysis by the Centre for Science and Environment (CSE).
