![]() Multiple studies have been conducted to determine the mechanism behind ozone's harmful effects, particularly in the lungs. Acute and chronic exposure to ozone has been shown to cause an increased risk of respiratory infections, due to the following mechanism. These changes lead to shortness of breath, wheezing, and coughing which may exacerbate lung diseases, like asthma or chronic obstructive pulmonary disease (COPD) resulting in the need to receive medical treatment. Inhaled ozone causes inflammation and acute -but reversible- changes in lung function, as well as airway hyperresponsiveness. Because ozone is gas, it directly affects the lungs and the entire respiratory system. Early death and problems in reproductive health and development are also shown to be associated with ozone exposure.Īcute ozone exposure ranges from hours to a few days. Ozone has been shown to affect the respiratory, cardiovascular and central nervous system. Hundreds of studies suggest that ozone is harmful to people at levels currently found in urban areas. ![]() For the last few decades, scientists studied the effects of acute and chronic ozone exposure on human health. ![]()
