                                      Old and Young

                          Young children whose lungs are developing, and
                        seniors and people with chronic disorders of the lungs
                                    and heart are more sensitive.



                                      Healthy People

               Everyone who works outside or engages in vigorous outdoor exercise for
                   prolonged periods during smog episodes is at increased risk of
                        experiencing adverse health effects caused by smog.

Health Risk:

• diminished lung growth in high ozone regions

• exacerbations of lung disease

• increased heart attacks and stroke
