Amid the persisting air pollution in the national capital from the last few weeks, the air quality index (AQI) remained in the ‘poor category’ in several parts across Delhi on Saturday, as per the Central Pollution Control Board (CPCB).
However, the city’s average AQI increased to 197, up from the 165 recorded a day earlier, according to the Central Pollution Control Board (CPCB).
Despite the rise, the AQI remained within the moderate range (101-200).
Out of the 38 monitoring stations across the city, 14 recorded ‘poor’ air quality, while the rest showed ‘moderate’ conditions. The AQI scale classifies readings as follows: 0-50 (good), 51-100 (satisfactory), 101-200 (moderate), 201-300 (poor), 301-400 (very poor), and above 400 (severe). Though the air quality showed improvement, the city continues to face challenges.
Earlier on Friday (December 6), the AQI rose to 186 at 8 am, up from 161 on Thursday, remaining within the “moderate” category for the third straight day, according to CPCB data. In light of the improved air conditions, the Centre’s air quality management body for Delhi-NCR withdrew pollution control measures under Stages III and IV of the Graded Response Action Plan (Grap).
Grap restrictions reduced to Stage II
With air quality improving to “moderate” for the first time this winter on Wednesday, authorities eased pollution control measures under Grap from Stage IV to Stage II on Thursday. Measures now in effect include banning coal and firewood in industries and commercial establishments, such as restaurants.
