Air Quality Index (AQI) in Vietnam 🇻🇳
Live Air Quality Index (AQI) and PM2.5 Levels in Vietnam
Currently, the Air Quality Index (AQI) in Hanoï, the capital of Vietnam, is measured at a score of 146. According to the US EPA health standard, this air quality rating is categorized as Sensitive. The current atmosphere in Hanoï is influenced by a PM2.5 (fine particulate matter) concentration of 53.7 µg/m³ and PM10 levels recorded at 54.5 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 38.4 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Vietnam 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 Ho Chi Minh City, Da Nang, Haiphong, Biên Hòa and Cần Thơ. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
