in Punjab and Haryana had a lot to do with the grey, suffocating day that Delhi suffered on Wednesday. The particles released by the field fires constituted 35% of the PM2.5 pollutants that enveloped the city, the highest so far this season.
Last year too, most farm fires were reported in the period between October 26 and November 5, according to data submitted by the state
pollution
boards to the Prime Minister’s Office.
