New Delhi: Delhi's air quality continues to be a major concern, with several areas recording hazardous pollution levels three days after Diwali celebrations. The Central Pollution Control Board (CPCB) reported that Anand Vihar recorded an Air Quality Index (AQI) of 428, falling into the 'severe' category. Other areas, including Akshardham (350) and India Gate (353), were classified as 'very poor'.

On Wednesday, the city was shrouded in dense smog, with the CPCB recording an average AQI of 345, also categorized as 'very poor'. Early morning readings in Ashok Vihar, Bawana, and Dilshad Garden reached 380, while parts of Delhi such as DTU, IGI Airport, and Lodhi Road remained in the 'poor' category, with AQI levels below 300.

Authorities have activated Stage II of the Graded Response Action Plan (GRAP) for Delhi-NCR, following forecasts from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM), warning that pollution levels may worsen in the coming days. Transport emissions accounted for 15.6% of Delhi’s pollution on Monday, while industries and other sources contributed 23.3%, according to the Decision Support System (DSS).

Residents have reported breathing difficulties and eye irritation due to the persistent smog. Health experts advise vulnerable groups, including children, the elderly, and those with pre-existing respiratory conditions, to limit outdoor activities and use protective measures such as N95 masks.

The ongoing pollution underscores the need for sustained efforts to address the city's air quality challenges, especially during and after major festivals.
