Ozone and the pollutants that cause it can be transported long distances…..
OZONE
VOC
NOx
Ozone pollution • Comes from many sources,
including–
Ozone is linked to:• shortness of breath
• chest pain when inhaling deeply
• wheezing and coughing and
• increased susceptibility to respiratory infections.

Public Health RisksAre SignificantPublic Health RisksAre Significant
Exposure to ozone increases…
• risk of premature mortality• pulmonary inflammation• the risk of asthma attacks• the need for medical treatment and for
hospitalization of persons with asthma• aggravation of COPD
And increasing evidence that it can• induce (cause) asthma
Who are at risk from ozone?
• Children with Asthma
• Adults with Asthma
• People w/ chronic lung diseases
• Seniors
• Children 18 & under

For 100 years, the American Lung Association has been the lead organization working to prevent lung disease and promote lung health. Lung disease death rates continue to increase while other leading causes of death have declined. The American Lung Association funds vital research on the causes of and treatments for lung disease. With the generous support of the public, the American Lung Association is “Improving life, one breath at a time.”
