Delhi’s air quality deteriorated further during the day, breaching the 400 mark, forcing the Commission for Air Quality Management (CAQM), the anti-pollution panel, to impose GRAP 4 restrictions in the national capital and its adjoining areas from tonight.
This comes hours after CAQM imposed GRAP 3 during the day when the air quality was hovering over 300. During the day, the panel said measures in the stage III of the Graded Response Action Plan (GRAP) have been implemented following “highly unfavourable meteorological conditions, including calm winds and very low mixing height”.
