Farm fires top pollutant list
November 08, 2024
|Hindustan Times
Despite fewer farm fires in Punjab and Haryana so far this year compared to 2023, they still accounted for over 20% of Delhi's total PM 2.5 (particulate matter with a diameter of less than 2.5 microns) in Delhi over the past three days, according to the Centre's Decision Support System (DSS).
It estimated the transport sector as the next biggest contributor at over 11% over the past two days.
Calculating the actual contribution of stubble smoke by factoring in the fire count recorded a day earlier, DSS said it accounted for 22.77% of Delhi's PM 2.5 on Wednesday, 20.38% on Tuesday and 23.3% on Monday a key factor that has kept Delhi's air quality index reading above 350 ("very poor") during this period.
At the same time, though transport-level winds, which blow at a height of over lkm are northwesterly and strong, surface-level winds in Delhi, which blow below 100 metres in height, have largely remained calm.
