Ground-level ozone is the type of ozone harmful to human health.
While ozone in the stratosphere (the upper atmosphere) protects us from the sun's harmful ultraviolet rays, ground-level ozone, also known as tropospheric ozone, is a pollutant formed when emissions from vehicles, industrial facilities, and other sources react chemically in the presence of sunlight. This reaction creates what we often recognize as smog.
Ground-level ozone can cause a variety of health problems, including:
- Respiratory Issues: It can trigger coughing, throat irritation, and airway inflammation.
- Reduced Lung Function: Ozone exposure can decrease lung capacity and make it difficult to breathe deeply.
- Aggravation of Existing Conditions: It can worsen chronic respiratory diseases such as asthma, emphysema, and bronchitis.
- Increased Susceptibility to Infections: Ozone can make individuals more susceptible to respiratory infections.
Certain groups are particularly vulnerable to the harmful effects of ground-level ozone, including:
- Children: Because they are often active outdoors and their lungs are still developing.
- The Elderly: Because they are more likely to have pre-existing respiratory or cardiovascular conditions.
- People with Lung Diseases: Such as asthma, emphysema, and chronic bronchitis.
- Outdoor Workers: Anyone who spends a significant amount of time outdoors, especially during periods of high ozone levels.
Therefore, it is crucial to monitor ozone levels and take precautions during ozone action days to protect your health.
