Ozone is the prime component of smog , the typical air pollution of urban areas. In Louisiana, ozone formation is largely dependent on summer weather. Health Effects of Ozone Ozone is associated with numerous health effects in humans. Eye irritation is characteristic of ozone pollution. Exposure to ozone can cause coughing, chest pain, and throat irritation.
Ozone can also increase susceptibility to respiratory infections.
In addition, ozone impairs normal functioning of the lungs and reduces the ability to perform physical exercise. Recent studies also suggest that even at lower ozone concentrations some healthy individuals engaged in moderate exercise for six to eight hours may experience symptoms. All effects of ozone are more severe in individuals with sensitive respiratory systems. In particular, studies show that exposure to moderate levels may impair the ability of individuals with asthma or respiratory disease to engage in normal daily activities. The potential chronic effects of repeated exposure to ozone are of even greater concern.
