Key pollutants measured in the Dubai air quality index
The Dubai air quality index is calculated using multiple pollutants that are known to affect health. Each pollutant contributes to the overall AQI Dubai value.
1. PM2.5 (Fine Particulate Matter)
PM2.5 consists of microscopic particles that can travel deep into the lungs. Elevated PM2.5 levels are a major contributor to poor AQI in Dubai, especially during dusty or stagnant weather conditions.
2. PM10 (Coarse Particulate Matter)
PM10 includes larger dust and sand particles. These are common in the Dubai air pollution index during construction activity and sandstorms and can irritate the eyes, nose, and throat.
3. Nitrogen dioxide (NO₂)
NO₂ is produced mainly by vehicle emissions and industrial activity. Higher NO₂ levels can worsen respiratory conditions and raise the air quality index of Dubai.
4. Carbon Monoxide (CO)
Carbon monoxide is a colorless, odorless gas released during fuel combustion. At elevated levels, it reduces oxygen delivery in the body and negatively affects the AQI Dubai.
5. Sulfur Dioxide (SO₂)
SO₂ comes from fuel burning and industrial processes. It may cause breathing discomfort and contribute to higher AQI values in Dubai.
6. Ozone (O₃)
Ground-level ozone forms when sunlight reacts with emissions. High ozone levels are a known factor in elevated Dubai air quality index readings, particularly during the hot summer months.
How is the AQI in Dubai calculated?
The AQI Dubai number shown on this page is calculated by measuring the concentration of individual pollutants in the air. Each pollutant is converted into a standardized index value based on health thresholds. The highest contributing pollutant determines the overall Dubai air quality index at that time. This approach ensures that the air quality index of Dubai reflects the most significant health risk present. By presenting air quality as a single number, the Dubai air pollution index allows residents to understand current conditions quickly without technical expertise.
