Pollution levels in the national capital are expected to drop on Tuesday due to an increase in wind speed even as air quality remained in the 'very poor' category in the morning.
According to the Meteorological (MeT) department, there is a possibility of strong winds in the next 24 hours.
At 9.44 am, Delhi's air quality index (AQI) was recorded at 365. The AQI at Vivek Vihar, Anand Vihar and ITO were registered at 410, 395 and 382 respectively.
On Monday, the city's average AQI stood at 370 at 8.30 pm due to a slight increase in wind.
An AQI between 0-50 is considered 'good', 51-100 'satisfactory', 101-200 'moderate', 201-300 'poor', 301-400 'very poor' and 401-500 'severe'. An AQI above 500 falls in the 'severe plus' category.
