GREEN "Good" |
OZONE: None | CO: None | PM: None |
51 |
YELLOW "Moderate" |
OZONE:
Unusually sensitive individuals may experience respiratory symptoms. Unusually sensitive people should consider limiting prolonged outdoor exertion. |
CO: None | PM: Unusually sensitive people should consider reducing prolonged or heavy exertion. |
101 |
ORANGE "Unhealthy for Sensitive Groups" |
OZONE:
Increasing likelihood of respiratory symptoms and breathing discomfort in active children
and adults and people with respiratory disease, such as asthma. Active children and adults and people with respiratory disease, such as asthma should limit prolonged outdoor exertion. |
CO: Increasing likelihood of reduced exercise tolerance due to increased cardiovascular symptoms, such as chest pain, in people with cardiovascular disease. People with cardiovascular disease, such as angina, should limit heavy exertion and avoid sources of carbon monoxide, such as heavy traffic. | PM: Increasing likelihood of respiratory symptoms in sensitive individuals, aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly. People with heart or lung disease, older adults, and children should reduce prolonged or heavy exertion. |
151 |
RED "Unhealthy" |
OZONE:
Greater likelihood of respiratory symptoms and breathing difficulty in active children and
adults and people with respiratory disease, such as asthma; possible respiratory effects
in general population. Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion. |
CO: Reduced exercise tolerance due to increased cardiovascular symptoms, such as chest pain, in people with cardiovascular disease. People with cardiovascular disease, such as angina, should limit moderate exertion and avoid sources of carbon monoxide, such as heavy traffic. | PM: Increased aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly; increased respiratory effects in general population. People with heart or lung disease, older adults, and children should avoid prolonged or heavy exertion. Everyone else should reduce prolonged or heavy exertion. |
201 |
PURPLE "Very Unhealthy" |
OZONE:
Increasingly severe symptoms and impaired breathing likely in active children and adults
and people with respiratory disease, such as asthma; increasing likelihood of respiratory
effects in general population. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion. |
CO: Significant aggravation of cardiovascular symptoms, such as chest pain, in people with cardiovascular disease. People with cardiovascular disease, such as angina, should avoid exertion and sources of carbon monoxide, such as heavy traffic. | PM: Significant aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly; significant increase in respiratory effects in general population. People with heart or lung disease, older adults, and children should avoid all physical activity outdoors. Everyone else should avoid prolonged or heavy exertion. |
