Delhi's Air Quality Remains "Poor," Says Government Agency
New Delhi: Delhi's air quality continues in the "poor" category this morning but is likely to improve slightly due to the favorable wind speed, as per the government agencies.
In Delhi, the air pollution had hit an eight-month high on Thursday but has reduced slightly on Friday with the favorable wind speed helping in the dispersion of the pollutants, even as the contribution if the stubble burning to Delhi's PM2.5 concentration rose to 18 percent.
The city recorded an air quality index (AQI) of 263 at 10 am. The 24-hour average AQI was 239 on Friday and 315 on Thursday, the worst since February 12 (AQI 320).
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'.
Whereas a senior scientist at the India Meteorological Department said that the maximum wind speed was 10 kilometers per hour on Friday. Today the wind direction is expected to be north-north westerly, which is likely to increase the impact of the stubble burning on Delhi's air quality.
As per the System of Air Quality and Weather Forecasting and Research, the contribution of the farm fires to Delhi's PM2.5 concentration rose from around 6 percent on Thursday to 18 percent on Friday.
On Friday the Central Pollution Control Board had said that the meteorological conditions in Delhi have been "extremely unfavorable" for dispersion of pollutants since September as compared to last year.
As per an analysis by the Council on Energy, Environment and Water, a Delhi-based think tank, transportation contribute the most - 18 to 39 percent - to Delhi's air pollution.
The road dust is the second-largest sources of air pollution in the city followed by industries (2 to 29 percent), thermal power plants (3 to 11 percent), and construction (8 per cent)
