The air quality in the Delhi-National Capital Region (NCR) has further deteriorated, with five monitoring stations registering an Air Quality Index (AQI) exceeding 300. According to data from the Central Pollution Control Board (CPCB), Anand Vihar recorded the highest AQI at a staggering 345.
Other areas also reported alarming AQI figures: DU North Campus and CRRI Mathura Road each recorded 307, while Dwarka Sector 8 and Wazirpur reported 314 and 325, respectively.
**Pollution Response: GRAP Stage-1 Activated**
In response to the worsening air quality, the Commission for Air Quality Management (CAQM) has activated Stage-1 of the Graded Response Action Plan (GRAP) across Delhi-NCR. This comes as AQI levels have fallen between 200 and 300, categorized as “poor.”
Stage-1 implementation mandates strict preventive measures, including the deployment of anti-smog guns and dust suppression activities at construction sites to control pollution sources.
**Pollution Sources: Transport Emissions Lead**
Data from the Decision Support System (DSS) identifies transport emissions as the largest contributor to Delhi’s pollution, accounting for 19.8% of total emissions. On Tuesday, the city recorded an AQI of 201, falling under the “poor” air quality category.
For reference, the CPCB classifies AQI as follows:
– 0-50: Good
– 51-100: Satisfactory
– 101-200: Moderate
– 201-300: Poor
– 301-400: Very Poor
– Above 400: Severe
**Weather Impact**
The India Meteorological Department (IMD) noted that Delhi’s minimum temperature on Wednesday was 18.3°C — slightly below the normal of 19.6°C. This marks the fifth consecutive day with minimum temperatures under 20°C for the 2025-26 winter season. The maximum temperature hovered around 33°C.
Meanwhile, relative humidity was high at 89% as recorded at 8:30 am, factors that could further affect air quality levels.
Residents are advised to take necessary precautions as the air pollution situation remains critical.
