Delhi's air pollution level dipped slightly Saturday but remained in the 'very poor' category due to poor dispersion of pollutants and stagnant meteorological conditions, authorities said.

The overall Air Quality Index of Delhi was recorded at 346, which falls in the 'very poor' category, according to data of the Central Pollution Control Board.

Wazirpur recorded 'severe' air quality, while 34 other areas recorded 'very poor' air quality, according to the CPCB data.

The PM2.5 level was recorded at 175. Fine particulates can be a matter of serious health concern than PM10 (particles in the air with a diameter of less than 10 micrometres).

As per the data by the Centre-run System of Air Quality Forecasting And Research, the PM10 level in Delhi stood at 302.

An AQI between 0 and 50 is considered 'good', 51 and 100 "satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.

The Indian Institute of Tropical Meteorology said the contribution from biomass fire is likely to be marginal on Friday and further for the next two days.

"Because of poor dispersion and stagnant meteorological conditions, no significant improvement is likely for the next two days," the IITM said.

The Centre-run System of Air Quality Forecasting And Research has said no deterioration is expected till November 5.

However, the authorities said there could be 'severe' deterioration from November 5 due to unfavourable meteorological conditions.
