Air quality in Delhi deteriorated beyond the “severe” level: CPCB data
After ground level dust storm in western India, the air quality in Delhi has deteriorated beyond the “severe” level on Wednesday, the Central Pollution Control Board data showed.
PM10 (particles with diameter less than 10mm) level was beyond severe at 778 in Delhi-NCR area and 824 in Delhi particularly, showed CPCB data.
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.”
“Such dust storms accompanied by high-speed winds (30-40 kmph) do not last too long due to which the air quality will return to normal by this evening,” he added.
According to CPCB, the air quality index at several places in Delhi crossed the 500-mark, with east Delhi’s Anand Vihar area recording an AQI of 891.
