Who is likely to be affected by exposure to ozone, and why?
People with respiratory disease, children, older adults, and people who are active may be most affected when ozone levels are high. Sensitive people who experience effects at lower ozone concentrations are likely to experience more serious effects at higher concentrations. Active children are the group at highest risk from ozone exposure because they spend more time outdoors. Ozone can aggravate symptoms for children with asthma. Active adults who exercise or work vigorously outside have a higher level of exposure to ozone than people who are less active.
