Ozone Action Season 2026

Ozone that is part of the Earth's upper atmosphere is helpful to us; it shields us from ultraviolet radiation. But ozone that accumulates at ground level is dangerous. Ozone at ground level damages lung tissue in people, and new research shows that it also damages growing plants and can affect agriculture. Breathing ozone can worsen bronchitis, emphysema, and asthma. "Bad" ozone (ground-level ozone) also can reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue. Healthy people also experience difficulty breathing when exposed to ozone pollution.

Ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. Because ozone forms in hot weather, anyone who spends time outdoors in the summer may be affected, particularly children, outdoor workers and people exercising. Children are especially vulnerable because of their developing lungs. Millions of Americans live in areas where the national ozone health standards are exceeded.

Ground-level ozone also damages vegetation and ecosystems. It leads to reduced agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased susceptibility to diseases, pests, and other stresses such as harsh weather. In the United States alone, ground-level ozone is responsible for an estimated $500 million in reduced crop production each year. Ground-level ozone also damages the foliage of trees and other plants, affecting the landscape of cities, national parks and forests, and recreation areas.

On a long, summer day:

1. Mix Volatile Organic Compounds (VOC’s) released from gasoline, paints, and solvents. Evaporate.
2. Stir in Nitrogen Oxide gases (Nox) released from cars and factories that burn fossil fuels.
3. Bake in heat and sunlight to trigger a chemical reaction to transform the emissions into ozone.

Half of the hydrocarbons that lead to ozone come from the actions of individuals — driving cars, maintaining a home, using chemicals like paint or lighter fluid. This means that individuals can have a significant effect on reducing ozone through conscious efforts.

People can reduce their exposure to ozone by changing the time of their activity or simply taking it easier on days when ozone levels are expected to be high. For example, a runner could run in the morning when ozone levels are lower, instead of in the afternoon when conditions tend to be more favorable for ozone formation. During the hottest time of the day, children and people with asthma or breathing problems should spend more time in air-conditioned areas.

Join Lake Erie West in taking action against ozone by applying some simple changes to your lifestyle and daily routine.

Reduce Ozone: 10 Tips for Individuals

1. Modify driving habits: Drive less, drive more slowly, share a ride, chain trips, walk or bike, or take public transportation.
2. Thoughtfully refuel: Refuel your car or gas cans in the morning or after 6 p.m., and avoid spilling gas or releasing vapors. Don't overfill your tank; stop at the first click.
3. Conserve energy in your home: Hang clothes outside to dry rather than operate a dryer, and set your thermostat to reduce air conditioner use.
4. Maintain your vehicle: Get a regular tune up and inflate your tires to the correct pressure.
5. Turn your car off: Park the car and walk into the building instead of using the drive through.
6. Change mowing habits: Mow the lawn less frequently or mow earlier in the morning or in the evening.
7. Maintain your home: Insulate and weather-strip your home.
8. Wash efficiently: Run the dishwasher and washing machines only when fully loaded.
9. Conserve electricity: Turn off lights and appliances when not in use.
10. Reduce fumes: Apply paint with rollers and brushes instead of sprays to cut down on fumes and save paint.
