Even though there's been little rainfall, moisture in the air has helped prevent them, she said. According to a fact sheet available online from the bureau, the Environmental Protection Agency sets standards for ozone and other air pollutants. For each pollutant, there are two standards. The primary standard is set to protect health, regardless of the cost. The secondary standard protects public welfare.
Public welfare includes effects on soil, water, property, animals and visibility.
When the ground level ozone level is high, it can cause eye soreness and irritation of the respiratory tract, headaches and dryness of the mouth and throat. Children, the elderly, and people with pre-existing lung disease such as emphysema, asthma and chronic bronchitis are especially susceptible to ground level ozone. All others, especially children, should limit outdoor exertion. Re-energize your workouts and your body with variety. And nowhere is that more true than exercise.
