What do we know about ozone and health? EPA’s Integrated Science Assessment (ISA) ● Assessment of the current scientific studies and knowledge about the effects of ozone on public health ● Scientific basis for the establishment of the most current national air quality standards for ozone ● New ISA coming out in 2020 7 https://www.epa.gov/isa/integrated-science-assessment-isa-ozone-and-related-photochemical-oxidants

What do we know about ozone and health? ● Causal relationship between short-term ozone exposure and respiratory health effects ● People most likely to experience health effects caused by ozone include: Children ○ Older adults ○ People with asthma, emphysema, or other lung diseases ○ People who exercise or work outside ○ ● Health effects can include: Cough, shortness of breath, wheezing, throat irritation ○ Asthma symptoms and increased need for asthma medication ○ Healthcare visits for respiratory symptoms ○ ● Varying levels of evidence for effects on other organ systems and effects of long-term exposure 8 https://www.epa.gov/ground-level-ozone-pollution/health-effects-ozone-pollution https://www.cdc.gov/air/ozone.html

8-hour Average Ozone (ppb) Category EPA-Recommended Actions 0-54 Good None 55-70 Moderate There may be a small number of people who are unusually sensitive to this level of ozone. Those people should consider reducing prolonged or heavy outdoor exertion. 71-85 Unhealthy for People with lung disease (such as asthma or emphysema), children, older adults, and sensitive groups people who are active outdoors should reduce prolonged or heavy outdoor exertion. 86-105 Unhealthy People with lung disease (such as asthma or emphysema), children, older adults, and people who are active outdoors should avoid prolonged or heavy outdoor exertion. Everyone else should reduce prolonged or heavy outdoor exertion. 106-200 Very Unhealthy People with lung disease (such as asthma or emphysema), children, older adults, and people who are active outdoors should avoid all outdoor exertion. Everyone else should reduce outdoor exertion. 9
