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 64. 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 16.1 ยตg/mยณ and PM10 levels recorded at 16.9 ยตg/mยณ. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 9.9 ยตg/mยณ.

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.

Cambodia Air Quality: Major Cities Index

* Air Quality Index (AQI) data for Cambodia is calculated using the US EPA standard. Information is processed from multiple monitoring stations detecting PM2.5, PM10, and gaseous pollutants to ensure accuracy for respiratory health planning.

Understanding Air Quality Levels

Good (0-50)

Air is fresh and healthy. Safe for all outdoor activities.

Moderate (51-100)

Acceptable air quality, though sensitive groups should monitor comfort.

Unhealthy (Sensitive) (101-150)

Vulnerable groups (children, elderly) should limit outdoor exertion.

Unhealthy (151-200)

Everyone begins to experience health effects. Stay indoors where possible.

Very Unhealthy (201-300)

Significant health impact for entire population. Emergency conditions.

Hazardous (301+)

Serious health alert: everyone may experience serious life-threatening effects.

Good (0-12)

Fine particles are at minimal, safe levels. Air is optimal.

Moderate (12-35)

Acceptable air, but haze may be present in urban areas.

Sensitive (35-55)

Individuals with heart or lung disease should limit activity.

Unhealthy (55-150)

Particulate levels high enough to cause respiratory irritation.

Very Unhealthy (150-250)

Heavy haze. High risk to cardiovascular health for the public.

Hazardous (250+)

Lethal particulate concentrations. Critical neurological and lung risk.

Good (0-54)

Low levels of dust and coarse particles. Environment is safe.

Moderate (55-154)

Coarse particles may trigger coughing in sensitive groups.

Sensitive (155-254)

Visible dust pollution. Sensitive groups should avoid heavy labor.

Unhealthy (255-354)

Widespread respiratory impacts likely for the population.

Very Unhealthy (355-424)

Dangerous dust and debris levels. Significant warnings issued.

Hazardous (425+)

Extremely high concentrations. Stay inside with filtration.

Good (0-54)

Surface ozone levels are within a safe, natural range.

Moderate (55-70)

Acceptable air, but sensitive individuals may feel chest tightness.

Sensitive (71-85)

Rising ozone can trigger airway inflammation in active children.

Unhealthy (86-105)

Avoid heavy outdoor work during the hottest part of the day.

Very Unhealthy (106-200)

Serious lung function reduction likely across the public.

Hazardous (201+)

Emergency ozone levels. Risk of permanent lung tissue damage.

Good (0-53)

Nitrogen levels are optimal. Safe for everyone.

Moderate (54-100)

Typical background levels for high-density urban areas.

Sensitive (101-360)

Increased risk of respiratory infections for vulnerable groups.

Unhealthy (361-649)

Significant airway inflammation likely near traffic zones.

Very Unhealthy (650-1249)

Acute respiratory distress potential. High-risk groups stay indoors.

Hazardous (1250+)
