Delhi air quality shows slight improvement, 10 stations record 'severe' AQI

Despite a slight dip in AQI, Delhi continues to grapple with dangerously high pollution levels, with dense smog reducing visibility across the city

Delhi saw a marginal improvement in air quality on Tuesday morning, though pollution levels remained alarming in the capital. The Central Pollution Control Board (CPCB) recorded an average Air Quality Index (AQI) of 377 at 8 am, placing it in the ‘very poor’ category. This was a slight improvement from December 15, when the AQI had reached 427 in the ‘severe’ category around 4 pm.

 

Earlier on Monday, most monitoring stations in the city had reported ‘severe’ AQI, with some stations hitting the maximum index value of 500. On Tuesday, out of 39 CPCB stations, ten remained in the ‘severe’ range, two reported ‘poor’ AQI, and the remaining 27 recorded ‘very poor’ levels. Anand Vihar station recorded AQI at 406, remaining in the ‘severe’ category.

Actionable recommendations to curb emissions are expected in future sessions.

 

Meanwhile, with air quality reaching dangerous levels, the Delhi government has issued a circular directing schools to shift to online classes for students up to grade five until further notice. This follows the imposition of stage IV restrictions under the Graded Response Action Plan (Grap) to limit pollution in the city.
