Answer:
*Who is at Most Risk from Ground-level Ozone?*
While everyone is exposed to ozone at some level, several groups of people are more sensitive. If you or someone you know is at risk, consult your physician to learn more about precautions to reduce or prevent exposure to ozone.
1. People with existing lung diseases can be particularly sensitive to ozone due to it being in the air we breathe. The effects of ozone on lung diseases may include increased medication use, doctor and emergency room visits, and hospital admissions. These lung diseases may include asthma and chronic obstructive pulmonary disease or “COPD”, which includes chronic bronchitis and emphysema.
2. Children, including teenagers, have lungs that are still developing and are more likely to have asthma. In addition to these sensitivities, they are generally outdoors more often. Outdoors, especially during warmer weather, have higher levels of ozone.
3. Older adults are more likely to have pre-existing lung disease and are therefore more sensitive to ozone.
4. Active people outdoors, of all ages, are more sensitive to ozone. As mentioned previously, the outdoor air contains higher levels of ozone. Those who participate in physical activity tend to breathe faster and deeper, drawing more ozone into the body. These people include both those who exercise outdoors or do physical work outdoors.
5. People with reduced intake of certain nutrients are also more susceptible to ozone. Those with a reduction or deficit of vitamins C and E are at a greater risk from ozone exposure.
6. Some healthy people may be more sensitive to ozone even without any of the risk factors that the other sensitive groups have. This category applies to those who may experience health effects at lower ozone levels than the average person
