Delhi air pollution
The Air quality across several parts of Delhi remained in the "severe" category on Friday morning, November 15, with a thick layer of smog once again blanketing the National Capital Region, including Noida, Ghaziabad and Gurugram
The deteriorating air quality index or AQI prompted the Commission for Air Quality Management (CAQM), the central pollution watchdog, to invoke restrictions under the third stage of the graded response action plan (GRAP), including a ban on construction activities and plying vehicles on BS-III petrol and BS-IV diesel vehicles in the city and NCR. The restrictions will come into force at 8am on Friday. The Delhi government also announced that due to the alarming levels of pollution, physical classes for primary schools will not be held till further orders, but online classes can continue. According to the Central Pollution Control Board (CPCB) data, the AQI in Delhi's Anand Vihar was 441 at 6am on Thursday.
