The Air Quality Index (AQI) in the national capital was at its lowest this year on Sunday, with PM 2.5 levels at 56.
The air quality has remained in the “satisfactory category” during the first week of July, according to data from the Central Pollution Control Board (CPCB), PTI reported.
AQI, which was under 100 for seven days in June, has further improved due to changing wind patterns and improved weather across the national capital.
An AQI of 51 to 100 is considered “satisfactory”, while 101 to 200 is ranked as “moderate” and 201 to 300 is ranked as “poor” as per air quality standards of CPCB. Numbers between 301 to 400 are considered as”very poor”, and 401 to 500 are ranked as “severe”.
Anything beyond “moderate” air quality causes breathing discomfort to people with lung diseases, asthma and heart diseases.
