New Delhi: The air level in the capital turned very bad on Tuesday, ahead of Diwali according to Centre-run System of Air Quality and Weather Forecasting And Research (SAFAR).
According to the air bulletin of the Central Pollution Control Board, the Air Quality Index (AQI) in the capital stood at 303 on Tuesday. It is expected that for the next two days it will be very bad. On Tuesday, stubble pollution was only 6 percent. However, the cases of stubble burning have come down significantly as compared to Monday.
Indian Meteorological Department (IMD) too said that the air quality over Delhi-NCR is likely to remain in the lower end of the ''Poor'' to ''Very Poor'' categories on November 2 and November 3.
''The air quality is likely to deteriorate on November 5 and November 6 but remain in the "Very Poor" category,'' it added.
Blowing wind can help in getting relief from the air pollution despite the increase cases of stubble burning. Reportedly, on Tuesday, stubble was burnt at 1789 places but the stubble pollution was only 6 percent. However, the burning of stubble on November 4 will also affect the air of the capital as from the same date, the direction of the winds will turn north-westerly, due to which the stubble smoke will start reaching the capital.
