What Health Effects Are Associated with Ozone Exposure?

Exposure to ambient ozone, even at low levels, may trigger a variety of health problems, especially in vulnerable populations such as children, the elderly, and those with pre-existing respiratory disease.

There are specific health effects associated with ozone exposure. The specific health effects include:

• Ozone can irritate lung airways and cause inflammation;
• Repeated exposure to ozone pollution for several months may cause permanent lung damage;
• Even low-level exposure can result in aggravated asthma, reduced lung capacity, and increased susceptibility to respiratory illnesses; and
• Studies have linked hospital admissions and emergency room visits to ground-level ozone exposure.

Ozone pollution can harm urban trees and other vegetation.
