Delhiites breathed easy yesterday as pollution levels in the national capital reduced significantly owing to gusty winds and rainfall in neighbouring areas.
The overall air quality index (AQI) fluctuated between 128 and 157, which falls in the moderate category, according to the Central Pollution Control Board's data.
Kuldeep Srivastava, a senior scientist at the Indian Meteorological Department said, rainfall in Punjab, Haryana, and nearby areas due to a western disturbance reduced the effect of stubble burning on the city's air quality.
He added, winds clocking 20-25 kilometres per hour will continue to blow in Delhi for the next two to three days, which is favourable for air quality. But, the direction will completely change to northwesterly October 21 onwards.
The Ministry of Earth Sciences' air quality forecast and research service, SAFAR data showed the share of smoke from stubble burning in neighbouring states on Delhi's PM2.5 concentration was nil on Saturday. It will increase to five per cent today and to 15 per cent tomorrow. (AIR)
