Air Quality

• No health effects are expected.
  

• Unusually sensitive individuals may
  experience respiratory effects from
  prolonged exposure to ozone during outdoor
  exertion.
  

What can I do to protect my health?

• When ozone levels are in the “moderate”
  range, consider limiting prolonged outdoor
  exertion if you are unusually sensitive to
  ozone.

• If you are a member of a sensitive
  group,⁽¹⁾ you
  may experience respiratory symptoms (such as
  coughing or pain when taking a deep breath)
  and reduced lung function, which can cause
  some breathing discomfort.
  

What can I do to protect my health?

• If you are a member of a sensitive
  group,⁽¹⁾
  limit prolonged outdoor exertion. In
  general, you can protect your health by
  reducing how long or how strenuously you
  exert yourself outdoors and by planning
  outdoor activities when ozone levels are
  lower (usually in the early morning or
  evening).
   
• You can check with your State air agency
  to find out about current or predicted ozone
  levels in your location. This information on
  ozone levels is available on the Internet at
  
  
  http://www.epa.gov/AIRNow.

• If you are a member of a sensitive
  group,⁽¹⁾ you
  have a higher chance of experiencing
  respiratory symptoms (such as aggravated
  cough or pain when taking a deep breath),
  and reduced lung function, which can cause
  some breathing difficulty.
   
• At this level, anyone could experience
  respiratory effects.

What can I do to protect my health?

• If you are a member of a sensitive
  group,⁽¹⁾
  avoid prolonged outdoor exertion. Everyone
  else-especially children-should limit
  prolonged outdoor exertion.
   
• Plan outdoor activities when ozone
  levels are lower (usually in the early
  morning or evening).
   
• You can check with your State air agency
  to find out about current or predicted ozone
  levels in your location. This information on
  ozone levels is available on the Internet at

• Members of
  sensitive groups⁽¹⁾
  will likely experience increasingly severe
  respiratory symptoms and impaired breathing.

   

• Many healthy
  people in the general population engaged in
  moderate exertion will experience some kind
  of effect. According to EPA estimates,
  approximately:
  – Half will experience moderately reduced
  lung function.
  – One-fifth will experience severely reduced
  lung function.
  – 10 to 15 percent will experience moderate
  to severe respiratory symptoms (such as
  aggravated cough and pain when taking a deep
  breath).

   

• People with asthma
  or other respiratory conditions will be more
  severely affected, leading some to increase
  medication usage and seek medical attention
  at an emergency room or clinic.
  

What can I do to
protect my health?

• If you are a
  member of a sensitive group,⁽¹⁾
  avoid outdoor activity altogether. Everyone
  elseespecially childrenshould limit
  outdoor exertion and avoid heavy exertion
  altogether.

   

• Check with your
  State air agency to find out about current
  or predicted ozone levels in your location.
