How is good stratospheric ozone formed?
Stratospheric ozone. Stratospheric ozone is natu- rally formed in chemical reactions involving ultraviolet sunlight and oxygen molecules, which make up 21% of the atmosphere. In the first step, sunlight breaks apart one oxygen molecule (O2) to produce two oxygen atoms (2 O) (see Figure Q2-1).
What of the following is a health risk associated with ground level ozone?
Breathing ground-level ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ozone also can reduce lung function and inflame the lining of the lungs. Repeated exposure may permanently scar lung tissue.
Can I be allergic to ozone?
Exposure to ozone, a component of smog, can irritate the lungs and worsen asthma and allergy symptoms.
How do you detect ozone?
Once inside an instrument, ozone can be measured by its absorption of ultraviolet (UV) light or by the electrical current produced in an ozone chemical reaction. The latter approach is used in the construction of “ozonesondes,” which are light- weight, ozone-measuring modules suitable for launching on small balloons.

How can we prevent ozone?
On Days when High Ozone Levels are Expected, Take these Extra Steps to Reduce Pollution:
- Choose a cleaner commute – share a ride to work or use public transportation.
- Combine errands and reduce trips.
- Avoid excessive idling of your automobile.
- Refuel your car in the evening when its cooler.
How can we reduce chlorofluorocarbons?
Buy air-conditioning and refrigeration equipment that do not use HCFCs as refrigerant. Buy aerosol products that do not use HCFCs or CFCs as propellants. Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage.
How can we reduce ozone in home?
Your best option might be to keep the windows closed, especially on warm and sunny days with little or no wind. Running an air purifier that can remove ozone in your home, either with a carbon filter or using PECO technology, may help lower ozone levels indoors.
