Delhi-NCR AQI: GRAP IV imposed as air quality slips into ‘severe+’ category

According to the Decision Support System for Air Quality Management, Delhi’s pollution load was led by the transport sector, which contributed 14.2 per cent, followed by Delhi and peripheral industries at 6.8 per cent. Construction activities accounted for 1.8 per cent, while residential sources contributed 3.6 per cent.

GRAP Stage IV is the highest level of restrictions imposed to curb pollution in the capital. The restrictions under Stage IV come in addition to the measures imposed in Delhi under Stages I, II and III of the action plan.

Among the monitoring stations recorded in the morning hours, 21 were in the ‘severe’ category with AQI readings of above 400, according to the CPCB.

Issuing guidelines, CAQM advised children, elderly citizens and those with chronic diseases to avoid stepping outside. The management also advised people to wear masks whenever stepping out.

In its official notice, the management also said that under GRAP IV, the entry of truck traffic into Delhi will also be restricted to curb pollution caused by vehicular movement, if the AQI worsens further.
