Live Air Quality Index (AQI) and PM2.5 Levels in Australia
Currently, the Air Quality Index (AQI) in Canberra, the capital of Australia, is measured at a score of 53. According to the US EPA health standard, this air quality rating is categorized as Moderate. The current atmosphere in Canberra is influenced by a PM2.5 (fine particulate matter) concentration of 10.3 µg/m³ and PM10 levels recorded at 11.7 µg/m³.
