What is one of the health impacts of ozone exposure?

1. Improved respiratory function

2. Reduced air quality

3. Irritation of eyes, throat, and nose

4. Increased physical endurance

The correct answer is: Irritation of eyes, throat, and nose

Ozone exposure is known to have several adverse impacts on human health, and one of the most common effects is the irritation of the eyes, throat, and nose. Ozone is a reactive gas that can cause inflammation in the respiratory system, leading to symptoms that include coughing, throat irritation, and eye discomfort. This is due to its ability to penetrate tissues and disrupt cellular function, which ultimately results in these irritating sensations. Improved respiratory function is not associated with ozone exposure; instead, ozone can exacerbate existing respiratory conditions such as asthma, leading to decreased lung function. Reduced air quality is a broader environmental concern resulting from high levels of ozone but does not directly relate to specific health impacts. Increased physical endurance is also incorrect, as ozone exposure can actually decrease physical performance and endurance due to its harmful effects on the respiratory system. Thus, irritation of the eyes, throat, and nose aptly represents a specific health effect directly linked to ozone exposure.
