Air Quality Index (AQI) in Dominican Republic 🇩🇴

Live Air Quality Index (AQI) and PM2.5 Levels in Dominican Republic

Currently, the Air Quality Index (AQI) in Santo Domingo, the capital of Dominican Republic, is measured at a score of 46. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Santo Domingo is influenced by a PM2.5 (fine particulate matter) concentration of 8.2 µg/m³ and PM10 levels recorded at 11.5 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 9.4 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Dominican Republic 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 Santiago de los Caballeros, Santo Domingo Oeste, Santo Domingo Este, San Pedro de Macorís and La Romana. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
