Bangladesh Air Quality Index (AQI) — Real-Time Pollution Map
Track real-time air quality (AQI), PM2.5, PM10, and NO2 levels across all 64 districts of Bangladesh. Get health advisories based on WHO standards.
Nationwide 64-District Atmospheric Telemetry Analysis
Current national average AQI stands at 76 with mean PM2.5 concentration of 12.7 µg/m³. Industrial kiln emissions, dry road dust, and vehicle exhaust maintain Moderate condition across key urban corridors.

US EPA Air Quality Index (AQI) Standard Scale
| AQI Range | Air Quality Category | Health Impact Description |
|---|---|---|
| 0 - 50 | Good | Air quality is satisfactory; poses little or no risk. |
| 51 - 100 | Moderate | Acceptable quality; minor risk for unusually sensitive individuals. |
| 101 - 150 | Unhealthy for Sensitive Groups | Members of sensitive groups may experience health effects. |
| 151 - 200 | Unhealthy | Everyone may begin to experience health effects; sensitive groups affected more severely. |
| 201 - 300 | Very Unhealthy | Health alert: everyone may experience more serious health effects. |
| 301 - 500 | Hazardous | Health warning of emergency conditions. The entire population is likely affected. |
Dynamic Level-Aware Health Guidance
ModerateAir quality is acceptable; no health risks for the general public.
Unusually sensitive individuals with severe asthma should limit prolonged heavy outdoor exertion.
Ventilate indoor spaces during non-peak traffic hours.
Stay hydrated and maintain routine daily activities.
Scientific Health Impacts of Fine Particulate Matter (PM2.5)
PM2.5 refers to microscopic ambient particles under 2.5 micrometers in diameter. Due to their minute scale, PM2.5 bypasses nasal cilia, penetrating deep into pulmonary alveoli and arterial blood vessels. High PM2.5 concentrations in urban Bangladesh from brick kilns and vehicular emissions require continuous public health monitoring.
