On our Air Quality Map you can check the data from state stations from all over the world! The Map shows Air Quality Index (AQI), whis is based on the level of six atmospheric pollutants, SO2, NO2, PM 10, PM 2.5, CO and O3 measured at monitoring stations in each city.
The higher the AQI value, the higher the level of air pollution and the greater the health risk. AQI is divided into six categories. Each category corresponds to a different level of health risk.
Good: Air quality is considered satisfactory, and air pollution poses little or no risk.
Moderate: Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for Sensitive Groups: Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy: Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Very Unhealthy: Health warnings of emergency conditions. The entire population is more likely to be affected.
Hazardous: Health alert: everyone may experience more serious health effects
