Air Quality Index (AQI) in Ireland 🇮🇪
Live Air Quality Index (AQI) and PM2.5 Levels in Ireland
Currently, the Air Quality Index (AQI) in Dublin, the capital of Ireland, is measured at a score of 12. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Dublin is influenced by a PM2.5 (fine particulate matter) concentration of 2.2 µg/m³ and PM10 levels recorded at 5.3 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 3.7 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Ireland 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 South Dublin, Cork, Limerick, Galway and Tallaght. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
