Pollutant Levels
Compared to WHO 24-hour guideline values
PM2.5
9.4μg/m³
Within WHO limits
WHO limit 15 μg/m³
Fine particles that penetrate deep into lungs. Main contributor to respiratory disease.
PM10
16.5μg/m³
Within WHO limits
WHO limit 45 μg/m³
Coarse particles from dust, pollen, and mould. Can irritate eyes and airways.
Ozone (O₃)
56.0μg/m³
Within WHO limits
WHO limit 100 μg/m³
Ground-level ozone formed by chemical reactions. Can cause breathing problems.
NO₂
24.5μg/m³
Within WHO limits
WHO limit 25 μg/m³
Nitrogen dioxide mainly from vehicle exhausts. Inflames airways and reduces immunity.
SO₂
1.5μg/m³
Within WHO limits
WHO limit 40 μg/m³
Sulphur dioxide from burning fossil fuels. Irritates the respiratory system.
CO
0.2mg/m³
Within WHO limits
WHO limit 4 mg/m³
Carbon monoxide from incomplete combustion. Reduces oxygen delivery to organs.

Air quality data facts
- PM2.5 (Fine particles): Tiny particles that penetrate deep into lungs. Main contributor to respiratory disease.
- PM10 (Coarse particles): Larger particles from dust, pollen, and mould. Can irritate eyes and airways.
- Ozone (O₃): Ground-level ozone formed by chemical reactions. High levels can cause breathing problems.
- Nitrogen Dioxide (NO₂): Mainly from vehicle exhausts. Inflames airways and reduces immunity.
- US AQI: Scale from 0 (Good) to 500+ (Hazardous). Higher numbers mean more health concerns.
- Pollen levels: Measured in grains per cubic meter. Higher counts affect people with allergies more severely.
