Residents of India's capital witnessed a slight reprieve as the air quality in Delhi showed a marginal improvement on Friday, November 21, 2025. However, the situation remains a significant cause for concern as the overall Air Quality Index (AQI) continues to languish firmly in the 'very poor' category.
Understanding Delhi's Current AQI Status
According to the latest data from the Central Pollution Control Board (CPCB), the air quality, while showing a minor positive shift, has not managed to escape the hazardous 'very poor' band. The CPCB's comprehensive scale categorizes air quality based on the AQI reading. An index between 0 and 50 is considered 'good', while 51 to 100 is 'satisfactory'. When the AQI rises to 101-200, it is labeled 'moderate'. The situation becomes worrisome from 201 to 300, which is 'poor', and critically deteriorates in the 301-400 range, classified as 'very poor'. The most severe category is 401-500, termed 'severe'.
What the 'Very Poor' Category Means for Public Health
The persistence of the 'very poor' air quality poses serious health risks to the city's inhabitants. Health experts consistently warn that prolonged exposure to such polluted air can lead to a host of respiratory and cardiovascular problems. The air is considered hazardous for sensitive groups and can cause breathing discomfort to the general population on prolonged exposure.
A Look Ahead for the National Capital
The minor improvement, though a positive sign, underscores the persistent and deep-rooted nature of Delhi's annual air pollution crisis. The city's struggle with smog, especially during the winter months, is a complex issue driven by a combination of factors including vehicular emissions, industrial pollution, and seasonal agricultural burning. Continuous monitoring and stringent measures are required to push the AQI into safer categories and safeguard public health.
