Classification | AQI | pm10 | pm2.5 | The health effects should be based only on 24-hour average values |
---|---|---|---|---|
Good | 1-50 | < 54 μg/m3 | < 9 μg/m3 | Air quality is considered satisfactory, and air pollution poses little or no risk |
Moderate | 51-100 | < 154 μg/m3 | < 35.4 μg/m3 | Air quality is acceptable; however, for some pollutants there may be moderate concern for a very small number of people who are unusually sensitive to air pollution |
Unhealthy for some | 101-150 | < 254 μg/m3 | < 55.4 μg/m3 | Members of sensitive groups may experience health effects, the general public is not likely to be affected |
Unhealthy | 151-200 | < 354 μg/m3 | < 125.4 μg/m3 | Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects |
Very Unhealthy | 201-300 | < 424 μg/m3 | < 225.4 μg/m3 | Health alert: everyone may experience more serious health effects |
Hazardous | ≥ 301 | > 424 μg/m3 | > 225.4 μg/m3 | Health warnings of emergency conditions, the entire population is more likely to be affected |
