On Wednesday, the air quality in Delhi had deteriorated beyond the ‘severe’ level because of a ground-level dust storm in western India which increased coarser particles in the air, the Central Pollution Control Board data said. The data showed that the PM10 (particles with diameter less than 10mm) level was beyond ‘severe’ category at 778 in Delhi-NCR area and 824 in Delhi particularly, leading to hazy conditions and limiting visibility.

Gufran Beig, a scientist at the Centre-run System of Air Quality and Weather Forecasting and Research institute, said “There was a ground-level dust storm in the western part of the country that increased drastically coarser particles in the air, causing a spike in pollution levels in Delhi.” An AQI between 0-50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor’, and 401-500 ‘severe’.
