The Commission for Air Quality Management (CAQM) on Friday invoked Stage 3 curbs under Graded Response Action Plan (GRAP) owing to the deteriorating air quality in the national capital.

The average air quality index in the national capital was recorded at 371 on Friday. The commission said the AQI of Delhi was exhibiting an increasing trend. It crossed 350 on Friday morning and was recorded 371 at 4 pm owing to dense fog, low mixing height, variable winds and unfavourable meteorological conditions.
