THE SIX LEVELS OF HEALTH CONCERN:  
 
GOOD (GREEN): AIR QUALITY IS CONSIDERED SATISFACTORY, AND AIR POLLUTION  
POSES LITTLE OR NO RISK.  
 
MODERATE (YELLOW): AIR QUALITY IS ACCEPTABLE, HOWEVER, FOR SOME POLLUTANTS  
THERE MAY BE A MODERATE HEALTH CONCERN FOR A VERY SMALL  
NUMBER OF PEOPLE. FOR EXAMPLE, PEOPLE WHO ARE UNUSUALLY  
SENSITIVE TO OZONE MAY EXPERIENCE RESPIRATORY SYMPTOMS.  
 
UNHEALTHY FOR SENSITIVE GROUPS (ORANGE): MEMBERS OF SENSITIVE GROUPS MAY  
EXPERIENCE HEALTH EFFECTS. THIS MEANS THEY ARE LIKELY  
TO BE AFFECTED AT LOWER LEVELS THAN THE GENERAL PUBLIC.  
FOR EXAMPLE, PEOPLE WITH LUNG DISEASE ARE AT GREATER RISK  
FROM EXPOSURE TO OZONE, WHILE PEOPLE WITH EITHER LUNG  
DISEASE OR HEART DISEASE ARE AT GREATER RISK FROM EXPOSURE  
TO PARTICLE POLLUTION. THE GENERAL PUBLIC IS NOT LIKELY TO  
BE AFFECTED WHEN THE AQI IS IN THIS RANGE.  
 
UNHEALTHY (RED): MEMBERS OF SENSITIVE GROUPS MAY EXPERIENCE MORE SERIOUS  
HEALTH EFFECTS.  
 
VERY UNHEALTHY (PURPLE): EVERYONE MAY EXPERIENCE MORE SERIOUS HEALTH EFFECTS.  
 
HAZARDOUS (MAROON): THE ENTIRE POPULATION IS MORE LIKELY TO BE AFFECTED.
