NEW DELHI : The national capital's air quality turned "poor" on Sunday as wind direction changed to northwesterly, increasing the contribution of smoke from stubble burning in neighbouring states to the pollution in the city. However on Sunday, pollution levels in Delhi shot up by around 100 points at air quality index (AQI), the Central Pollution Control Board data showed. The Ministry of Earth Sciences' air quality forecast and research service, SAFAR, said, "The overall air quality of Delhi is back in the poor category. Despite a ban on stubble burning in Punjab and Haryana, farmers continue to defy it amid lack of financial incentives. The Delhi government has on several occasions attributed the dip in the air quality to rampant stubble burning in neighbouring states.
