Delhi recorded its second highest pollution level of the year on Sunday and unfavourable meteorological conditions are likely to keep the air quality in the 'severe' category for the next couple of days, authorities said.
  
While the Central Pollution Control Board data showed the overall air quality index at 'severe' level of 446, the Centre-run System of Air Quality and Weather Forecasting  showed a higher level at 471.

This is the second highest pollution level of this year. The highest was recorded on November 8, a day after Diwali, when the AQI touched 571.

An AQI between 100 to 200 comes under the 'moderate' category, 201 and 300 is considered 'poor', 301 and 400 'very poor', while that between 401 and 500 is 'severe'.

According to experts, under the 'severe' category, even healthy people find it hard to breathe and doctors advise physical activity to be kept at a minimum.

On Sunday, 30 areas of the national capital recorded 'severe' air quality while it was 'very poor' in six, the CPCB said.
