Mumbai: No relief for northern states as they continue to witness severe air pollution, while the Air Quality Index (AQI) continues to oscillate between the ‘very poor’ and ‘severe’ category.
According to the System of Air Quality and Weather Forecasting And Research (SAFAR), as of 8 am Tuesday, the overall AQI improved and it was recorded in the ‘bad’ category. Particulate matter (PM) 10 was recorded at 154 and PM 2.5 at 96.
AQI between the range of 51 and 100 is called ‘satisfactory’, 101-200 is called ‘moderate’, 201-300 is considered ‘poor’, 301-400 falls in ‘very poor’ Category while 401-500 ard falls into the ‘dangerous’ category.
Delhi’s overall AQI has improved significantly since last week due to high wind speeds and boundary layer winds. However, the relief is likely to be short-lived and according to the SAFAR-forecasting model, winds are likely to be significantly slower.
Meanwhile, it has been reported that in the next 15 days the government will try and keep the dust down by using water.
Stubble burning in the neighboring states like Haryana, Punjab and Uttar Pradesh is considered one of the prime reasons for hazardous air quality in the national capital. It further deteriorates as it mixes with vehicular pollution and construction dust in the city.
