As air quality in the capital deteriorated to the ‘severe’ level for the first time this season on Monday, Environment Pollution (Prevention and Control) Authority chairperson Bhure Lal said measures such as vehicular regulation and strict anti-dust measures will have to be taken if the situation persists.
Meanwhile, the Ghaziabad administration ordered a temporary halt to construction activities in the region. The air quality index value in Delhi was recorded at 401, while it was 451 in Ghaziabad
Vehicular regulation and road-rationing schemes such as odd-even and stopping the entry of trucks in Delhi are part of the Graded Response Action Plan (GRAP), notified two years ago. Both restrictions are imposed if the ‘emergency’ pollution levels extend over 48 hours at a stretch.
Bad air quality at this time of the year is concentrated in Delhi-NCR and parts of Uttar Pradesh. Of the 70 cities where air quality is monitored by the Central Pollution Control Board, eight recorded ‘severe’ air quality (AQI value of more than 400) Tuesday.
