GRAP Stage 4 Reimposed In Delhi-NCR As AQI Crosses 400 Mark Into Severe Category

On this news report, the focus is on the deteriorating air quality in the Delhi-NCR region, which has led to the reimposition of Stage 4 of the Graded Response Action Plan (GRAP). The air quality index (AQI) in the national capital has surged past the 400 mark, entering the 'severe' category, with PM 2.5 levels reaching 428 and exceeding 450 in several areas. The unidentified speaker notes that 'Curbs will include a complete ban on construction and demolition activities' and a ban on the entry of non-BS6 diesel trucks. The Commission for Air Quality Management (CAQM) has also ordered all schools to shift to hybrid mode to protect students. These emergency measures will remain in place until pollution levels subside to Stage 2 or 3. The sudden spike in pollution is attributed to recent changes in weather conditions across the region.
