Ozone Pollution Alert Issued for North Texas
An ozone pollution alert is active for North Texas on Wednesday.
Dallas Fort Worth, TX, September 22, 2026 — An ozone pollution alert has been issued and is active for the North Texas region on Wednesday. The alert indicates that ozone levels are expected to reach unhealthy concentrations, particularly for sensitive groups.
Ozone, a gas that is a major component of smog, is formed when pollutants from cars, trucks, power plants, and industrial facilities react with sunlight. Ground-level ozone, unlike the ozone layer in the upper atmosphere which protects us from UV radiation, is harmful to human health. Hot, sunny days are typically when ozone pollution is most severe.
The specific agency or authority issuing the alert was not detailed in the summary. Similarly, the expected peak ozone levels or the exact time frame the alert will be in effect beyond Wednesday were not provided. Residents in North Texas are advised to be aware of the air quality conditions.
Health effects from breathing air with high ozone levels can include coughing, throat irritation, chest pain, and difficulty breathing. It can worsen bronchitis, emphysema, and asthma. Sensitive individuals, including children, the elderly, and people with lung diseases, are at higher risk. These groups may want to limit prolonged outdoor exertion or strenuous activity during periods of elevated ozone levels.
Further information regarding specific actions to take or details about air quality monitoring can typically be obtained from local environmental agencies. The alert serves as a notification for residents to be mindful of air quality throughout the day.
