1. Is ozone good or bad?
A. Ozone is good! It protects us from the sun's ultraviolet rays.
B. Ozone is bad! It irritates our lungs and aggravates asthma.
C. Both! Ozone up high in the stratosphere protects us from ultraviolet radiation, but ozone at ground level is unhealthy to breathe.
Ozone pollution also harms plant life. Reducing ozone pollution levels will help protect Washington's most treasured sites, including Mount Rainier National Park.
2. Do human activities produce ozone pollution?
C. Yes and no.
3. What activity contributes the most to Washington's ozone pollution levels?
A. Backyard barbecues
C. Garden and lawn care
D. Using paints and solvents
E. VOC emissions from plants
Some VOCs that form ozone come from natural sources. Human activities, however, are by far the biggest source of ozone-forming chemicals that lead to unhealthy air during hot summer weather.
4. What can you do to reduce ozone pollution?
A. If you have an alternative, don't drive. Walk, bike, or use transit.
B. If you must refuel, do so at night. The gas pump emits those same VOCs that evaporate from your gas tank on a hot day.
C. Maintain your vehicle. A vehicle in good working order runs cleaner and emits less pollution.
D. A, B, and C.
Although motor vehicles contribute the most, some popular summer activities that contribute to forming ozone pollution include mowing the lawn, painting the house, and using the barbecue. Here are some more ways you can reduce ozone:
- Use an electric or push lawn mower, or wait for cooler weather to mow the lawn.
- Avoid using pesticides and synthetic fertilizers in your yard. Instead, try these natural yard care tips.
- Use low-VOC house paints.
- Don't use lighter fluid when you fire up the grill.
