Ozone (O₃), a gas composed of three oxygen atoms, occurs naturally in the Earth’s stratosphere, where it forms a protective layer that shields us from harmful ultraviolet (UV) radiation. However, at ground level, ozone is a harmful air pollutant.
When is Ozone a Problem?
Ground-level ozone is a significant issue during the warmer months, typically from late spring through early fall (May to September). This is because ozone forms when pollutants from vehicles, industrial facilities, and other sources react with sunlight and heat. The problem worsens on hot, sunny days with little wind.
How Does Ozone Affect People?
Breathing in high levels of ground-level ozone can cause serious health issues, especially for sensitive groups, including children, older adults, people with lung diseases (such as asthma or COPD), and those who are active outdoors. Effects include:
Respiratory Problems – Coughing, throat irritation, and shortness of breath
Worsening Asthma & Lung Diseases – Increased attacks and hospital visits
Reduced Lung Function – Harder to breathe deeply, especially during exercise
Increased Risk of Infections – More susceptibility to respiratory illnesses
How Can You Help Reduce Ozone Gas Emissions?
You can help reduce ozone emissions by:
Reducing driving and idling time
Lowering home energy usage
Fueling automobile before 10 a.m. or after 6 p.m.
Using public transit.
To Reduce Your Exposure to Ozone
Check Air Quality Reports – Look for ozone alerts in your area
Limit Outdoor Activities – Especially during the afternoon when ozone levels peak
