What are some of the health effects from exposure to ozone? Ozone is very harmful to the lungs. Exposure to ozone can make breathing difficult, inflame the lungs and lining of the respiratory tract, lead to permanent lung damage, and make it harder for the body to fight respiratory diseases. Symptoms to watch for include coughing, shortness of breath, and chest tightness/chest pain.
Ozone is a gas that is naturally present in Earthâs. atmosphereâone that has markedly different effects. depending on its location. At Earthâs surface, where. ozone comes into direct contact with life forms, it primarily displays a destructive side. Because it. reacts strongly with biological systems, large con-. centrations of ozone near the ground prove toxic to. living things.
