Ozone Season Upon Us

Southern Arizona is now entering the time of the year when levels of the air pollutant ground-level ozone begin to climb. Fortunately, during most days from April to September, the air quality in Pima County is in the good or moderate range.

However, there are days when the air we breathe can be unhealthy, especially for those who are sensitive to ozone. Inflamed airways, difficulty breathing, coughing, and increases in asthma attacks are some of the health effects that can occur by breathing elevated levels of ozone air pollution.

Some of the best ways to minimize ground-level ozone include maintaining our vehicles, refueling in the evening, driving and idling our vehicles less, sharing rides, choosing one day a week to work from home (if you aren't already doing so), and reducing the use of gas-powered lawn and garden equipment.
