Who is sensitive to ozone?

Children, the elderly, and those with pre-existing lung problems, such as asthma, are sensitive to the health effects of ozone. Even healthy adults involved in moderate or strenuous outdoor activities can experience the unhealthy effects of ozone.

How does ozone affect human health?

Ozone is a major element of urban smog. Ozone can limit the ability to take a deep breath, and it can cause coughing, throat irritation, and breathing discomfort.
