Even healthy individuals who are exercising or working outdoors can be damaged by high levels of ozone. Ozone Sensitivity Groups of people that are most likely to be ozone-sensitive include children and adults who are active outdoors and people with compromised respiratory systems such as asthmatics. People who show sensitivity at low ozone concentrations are more likely to experience serious side effects if exposed to a higher concentration of ozone. Principle of Operation Ozone test strips are chemically treated to react with ozone. After 10 minutes, compare the test strip with the color scale on the test strip package.
Results display in four distinct colors from light yellow to dark yellow.
Each represents a certain level of ozone concentration. Ranging from 0.045 ppm to over 0.105 ppm. The EPA has determined that high exposure levels of ozone over an eight-hour period may cause negative health effects in sensitive people.
