Delhi witnessed a marginal improvement in air quality on Friday, with the overall Air Quality Index (AQI) slipping into the ‘poor’ category. Official data showed the city’s average AQI at 292, offering limited relief after pollution levels had touched the ‘severe’ mark earlier this week.
The improvement comes days after Delhi recorded an AQI of 412 on December 23, placing air quality firmly in the ‘severe’ category. Over the last two days, pollution levels have shown a gradual decline across multiple monitoring stations in the national capital.
Some stations record moderate air quality
According to data from the Central Pollution Control Board’s Sameer mobile application, three locations reported ‘moderate’ air quality as of early morning. Lodhi Road-IITM recorded an AQI of 160, Lodhi Road-IMD stood at 194, while Najafgarh reported 188.
Several other parts of the city remained in the ‘poor’ category. Areas including Aya Nagar, CRRI Mathura Road, Dr Karni Singh Shooting Range, Dwarka Sector 8, IGI Airport Terminal 3, IIT Delhi, Jawaharlal Nehru Stadium and Mandir Marg recorded AQI values ranging between the low 200s and high 200s.
Very poor air persists in pollution hotspots
Despite the overall improvement, many parts of Delhi continued to struggle with ‘very poor’ air quality. Anand Vihar, Bawana, Jahangirpuri, Narela, Nehru Nagar, Sonia Vihar and Vivek Vihar reported some of the highest AQI readings, with values crossing 350 at several locations.
In view of the easing pollution levels, the Commission for Air Quality Management lifted Graded Response Action Plan (GRAP) Stage-IV restrictions across the Delhi-National Capital Region on December 24. Officials indicated that further relaxations could be considered if the downward trend in pollution continues.
Mixed air quality across NCR
Air quality in neighbouring NCR regions showed mixed trends. In Haryana, Bahadurgarh recorded a ‘very poor’ AQI of 301, while Gurugram’s overall AQI stood at 270, falling in the ‘poor’ category. One monitoring station in Gurugram’s Sector 51 reported ‘very poor’ air quality with an AQI of 375. Dharuhera also remained in the ‘poor’ range.
In Uttar Pradesh, pollution levels stayed elevated. Ghaziabad recorded an overall AQI of 344, with all monitoring stations reporting ‘very poor’ air quality. Greater Noida’s AQI stood at 362, while Knowledge Park-V and Knowledge Park-III recorded AQI levels of 386 and 337 respectively. Noida also remained in the ‘very poor’ category with an AQI of 334.
Authorities have restricted the entry of non-BS 6 vehicles into Delhi, a move that has blocked around 1.2 million older vehicles registered outside the city. Vehicular emissions remain a key contributor to winter pollution, with experts estimating that vehicles account for up to 40 per cent of particulate matter pollution in the NCR.
