Experts believe that the air quality is likely to deteriorate marginally on Friday. The national capital witnessed six 'severe' air days on the trot from November 4 to November 9, according to Central Pollution Control Board data. According to reports, a change in the wind direction - from north westerly to north-north easterly - was the reason behind the dip in pollution levels as it reduced the contribution of stubble burning significantly, experts said.
