Indice de qualité de l'air (AQI) à Brésil 🇧🇷
Indice de qualité de l'air (IQA) en direct et niveaux de PM2.5 en Brésil
Currently, the Air Quality Index (AQI) in Brasilia, the capital of Brésil, is measured at a score of 28. 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 5.0 µg/m³ and PM10 levels recorded at 5.5 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 14.8 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Brésil 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 et 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.

Comprendre les niveaux de qualité de l'air
Air is fresh and healthy. Safe for all outdoor activities.
Acceptable air quality, though sensitive groups should monitor comfort.
Vulnerable groups (children, elderly) should limit outdoor exertion.
Everyone begins to experience health effects. Stay indoors where possible.
Significant health impact for entire population. Emergency conditions.
Serious health alert: everyone may experience serious life-threatening effects.
Fine particles are at minimal, safe levels. Air is optimal.
Acceptable air, but haze may be present in urban areas.
Individuals with heart or lung disease should limit activity.
Particulate levels high enough to cause respiratory irritation.
Heavy haze. High risk to cardiovascular health for the public.
Lethal particulate concentrations. Critical neurological and lung risk.
Low levels of dust and coarse particles. Environment is safe.
Coarse particles may trigger coughing in sensitive groups.
Visible dust pollution. Sensitive groups should avoid heavy labor.
Widespread respiratory impacts likely for the population.
Dangerous dust and debris levels. Significant warnings issued.
Extremely high concentrations. Stay inside with filtration.
Surface ozone levels are within a safe, natural range.
Acceptable air, but sensitive individuals may feel chest tightness.
Rising ozone can trigger airway inflammation in active children.
Avoid heavy outdoor work during the hottest part of the day.
Serious lung function reduction likely across the public.
Emergency ozone levels. Risk of permanent lung tissue damage.
Nitrogen levels are optimal. Safe for everyone.
Typical background levels for high-density urban areas.
Increased risk of respiratory infections for vulnerable groups.
Significant airway inflammation likely near traffic zones.
