New Delhi, June 15: A total of 11 flights arriving or departing from Chandigarh Airport has been canceled due to poor visibility, ANI reported on Friday. In a fresh development, all IndiGo domestic flights and 5 more flights arriving or departing have been canceled due to poor visibility. At least 33 flights including three international were canceled on Thursday as well after dust storm hit the city.

For last three days, the air quality in Delhi has 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 showed. The authorities also warned that dusty conditions were likely to prevail for another 3-4 days and advised people to avoid staying outdoors or long hours.

The air quality deteriorated because of dust storms in western India, particularly Rajasthan, which increased coarser particles in the air, the Central Pollution Control Board said.

The CPCB data showed that the PM10 (particles with a diameter less than 10mm) level was beyond “severe” at 778 in Delhi-NCR area and 824 in Delhi particularly, leading to hazy conditions and limiting visibility.

The CPCB said the pollution of this season was very different from that of last year. In November last year, both PM2.5 and PM10 had spiked which was posing a serious health hazard. However, the current increase in levels of pollution is mainly due to a drastic increase in coarse particles in the air which has caused a spike in PM10 level but PM2.5 is not as high as that of last year.
