Phoenix, AZ – Air quality conditions across parts of Arizona have declined this week, prompting state environmental officials to urge residents to limit activities that contribute to pollution, especially vehicle emissions during peak daytime hours.
According to the Arizona Department of Environmental Quality (ADEQ), elevated ozone pollution has reached unhealthy levels, particularly during the afternoon and early evening when sunlight and vehicle exhaust combine to form ground-level ozone. These conditions can worsen respiratory issues and pose risks to children, older adults, and people with asthma or heart disease.
ADEQ officials are asking residents statewide to take several simple steps to reduce emissions and help improve air quality immediately. Recommended actions include limiting vehicle idling, reducing daytime driving when possible, refueling vehicles later in the day, and carpooling to cut down on the number of cars on the road.
Ozone pollution is most common during Arizona’s warmer months and often intensifies during high-pressure weather systems that trap pollutants near the ground. While the pollution may not always be visible, experts warn that breathing elevated ozone levels can cause coughing, throat irritation, shortness of breath, and increased emergency room visits.
Officials emphasized that even small behavior changes can make a measurable difference. Reducing driving during peak ozone hours—typically late morning through early evening—can help slow the buildup of pollution and protect vulnerable populations.
Residents are encouraged to check daily air quality forecasts and advisories through ADEQ’s official website at azdeq.gov/forecasting. The agency also provides color-coded alerts to help residents understand when air quality may pose a health risk.
Those living in Maricopa County and the greater Phoenix metro area are often among the most affected, but officials say ozone pollution can impact communities across the state.
