Classification Index pm2.5 The health effects should be based on 24 hours average values only.
 Good  1-50 < 12 μg/m3 Air quality is considered satisfactory, and air pollution poses little or no risk
 Moderate  51-100 < 35.4 μg/m3 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  101-150 < 55.4 μg/m3 Members of sensitive groups may experience health effects. The general public is not likely to be affected.
 Unhealthy  151-200 < 150.4 μg/m3 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
 Very Unhealthy  201-300 < 250.4 μg/m3 Health warnings of emergency conditions. The entire population is more likely to be affected
