Delhi's air quality returns to a 'very poor' category with AQI at 303

Air quality in Delhi-NCR remains a concern, with several key areas in the national capital classified as 'very poor' and notable fluctuations in pollution levels

This report has been updated  Delhi’s air quality remains in the ‘very poor’ category, with an Air Quality Index (AQI) of 303 at 6 am today (Nov 28), as per the Central Pollution Control Board (CPCB). This follows a brief dip to ‘poor’ on Tuesday. Key locations like Mundka and Anand Vihar recorded AQI levels over 350. The city is experiencing reduced visibility and a persistent layer of smog, particularly around landmarks like India Gate. Schools continue hybrid operations to reduce children's exposure, as PM2.5 and PM10 levels pose significant health risks.

 

Air quality index in different parts of Delhi

 

Air quality continues to be a significant concern, with several key locations across the city reporting ‘very poor’ conditions and notable fluctuations in pollution levels. As of 8.30 am today, the Central Pollution Control Board recorded the following AQI levels: ITO at 291, Chandni Chowk at 308, Major Dhyan Chand National Stadium at 299, Patparganj at 330, Mandir Marg at 297, Lodhi Road at 255, and Anand Vihar at 362.

 

AQI levels: What they mean for your health

 

Air Quality Index is the measure of pollution levels. AQI values between 0 and 50 indicate ‘good’ air quality, posing minimal health risks, while levels from 51 to 100 are considered ‘satisfactory,’ with minor pollution and negligible effects. AQI values between 101 and 200 are categorised as ‘moderate,’ which may cause discomfort for sensitive individuals, such as those with respiratory issues.

 

Levels from 201 to 300 are classified as ‘poor’, potentially affecting vulnerable groups like children and the elderly. ‘Very poor’ air quality, with AQI values between 301 and 400, poses significant health risks, particularly for individuals with pre-existing conditions. AQI readings from 401 to 450 fall into the ‘severe’ category, affecting a broader population and causing respiratory distress. Anything above 450 is classified as ‘severe plus’, representing extremely hazardous conditions with serious health implications for all. Recognising these levels is essential for taking precautions during high-pollution periods.

 

Restrictions under Graded Response Action Plan

 

The Supreme Court has upheld Stage-IV restrictions under the Graded Response Action Plan (Grap), enforcing several anti-pollution measures. Due to severe air pollution, the Commission for Air Quality Management (CAQM) earlier ordered all schools in Delhi and the National Capital Region (NCR) to adopt a hybrid format for classes up to grade 12, combining physical and online sessions.
