Stubble burning share in Delhi's pollution rises to 26% as farm fires rise

The share of stubble burning in Delhi PM2.5 pollution rose to 26 per cent on Sunday, the highest this year so far, amid an increase in farm fires and favourable conditions for transport of emissions to Delhi-NCR. On Saturday, farm fires accounted for 21 per cent of the PM2.5 pollution in the national capital. PM2.5 are fine particles that are 2.5 microns or less in diameter and can travel deep into the respiratory tract, reaching the lungs and entering the bloodstream. The contribution of stubble burning to Delhi's PM2.5 pollution remained low (up to 7 per cent) till Friday due to a prolonged rain spell in early October and slow transport-level winds which were not strong enough to carry smoke from farm fires to the national capital. On Diwali (October 24), stubble burning contributed five to eight per cent to the total PM2.5 pollution in Delhi. The share of farm fires in Delhi's PM2.5 pollution was 25 per cent on Diwali in 2021, 32 per cent in 2020 and 19 per cent in 2019. The I
