Live Air Quality Index (AQI) and PM2.5 Levels in Brazil
Currently, the Air Quality Index (AQI) in Brasilia, the capital of Brazil, is measured at a score of 25. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Brasilia is influenced by a PM2.5 (fine particulate matter) concentration of 4.5 µg/m³ and PM10 levels recorded at 5.3 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Brazil based on industrial output, traffic density, and local weather patterns. Real-time pollution data and respiratory health alerts are also being actively monitored in cities like São Paulo, Rio de Janeiro, Belo Horizonte, Salvador and Fortaleza. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
