What is the main risk associated with ozone exposure over time?

The primary risk associated with long-term exposure to ozone is respiratory problems. Ozone, as a reactive gas, can cause a range of adverse effects on the respiratory system. It can irritate the airways, leading to symptoms such as coughing, throat irritation, and shortness of breath. Over time, chronic exposure can aggravate asthma and other pre-existing lung conditions, resulting in decreased lung function.

While the other options may reflect certain risks related to ozone, such as skin irritation or damage to materials like rubber, they do not encompass the most significant health concern that arises from extended ozone exposure. Vision impairment is also a consideration, but the evidence of ozone's respiratory impact is far more pronounced and significant in health assessments. Therefore, understanding the impact of ozone on respiratory health is critical, particularly for individuals who may be exposed to higher levels of ozone, such as those living in urban areas with heavy traffic or industrial activity.
