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.
