Air Quality Index (AQI) in Cambodia 🇰🇭
Live Air Quality Index (AQI) and PM2.5 Levels in Cambodia
Currently, the Air Quality Index (AQI) in Phnom Penh, the capital of Cambodia, is measured at a score of 56. According to the US EPA health standard, this air quality rating is categorized as Moderate. The current atmosphere in Phnom Penh is influenced by a PM2.5 (fine particulate matter) concentration of 11.9 µg/m³ and PM10 levels recorded at 13.3 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 6.3 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Cambodia 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 Takeo, Siem Reap, Battambang, Paoy Paet and Kampong Chhnang. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
