Delhi’s air pollution level continue to remain very poor. The air quality, which has improved slightly compared to last few days, continue to remain in the category ‘very poor’.
The improvement in air quality was not significant as rainfall was not sufficient enough and wind speed was also moderate.
Yesterday on Thursday, according to the System of Air Quality and Weather Forecasting And Research (SAFAR), the air quality index (AQI) was recorded at 329.
For your information, an AQI between 0-50 is considered as good, 51-100 is marked as satisfactory, 101-200 is categorized as moderate, 201-300 is poor, 301-400 is very poor and 401-500 is severe.
The overall PM 2.5 (fine particulate matter in the air with a diameter of less than 2.5 micrometre) level in Delhi was recorded at 157 in the ‘very poor’ category while the PM10 (fine particulate matter in the air with a diameter of fewer than 10 micrometre) level was recorded at 265 in the ‘poor’ category on Thursday morning.
In winter season, Delhi’s are quality stays between ‘very poor’ and ‘severe’ quality.
SAFAR earlier predicted that the AQI would oscillate between ‘poor’ and ‘very poor’ range for a couple of days.
Other weather conditions remained more or less the same. High air holding capacity and moderate fog are working unfavorably for the air quality. Surface winds that were recorded at a speed of 3.3 kmph in the southerly direction are partially favorable for the dispersion of pollutants.
