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. Because wind can carry ozone and its precursors hundreds of miles, even residents far away from urban centers and sources of pollution can be at risk. 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. How Does Ozone Pollution Affect Ecosystems and the Environment? Ozone pollution can damage vegetation and ecosystems within and downwind of cities. Fo
