Ozone and Foliar Injury

	Portable Ozone Monitoring Station Importance / Issues Exposure to ozone above the National Ambient Air Quality standard may affect human health, causing acute respiratory problems, aggravation of asthma, temporary decreases in lung capacity in some adults, inflammation of lung tissue, and impairment of the body’s immune system. Ozone also affects vegetation in national parks. Research shows that some plants are more sensitive to ozone than humans, and effects to plants occur well below the National Ambient Air Quality standard. Ozone causes considerable damage to vegetation throughout the world, including agricultural crops and native plants in natural ecosystems. Preliminary Monitoring Objectives Use nearby, off-site state-operated ozone monitors as an estimate of the ozone levels at each Cumberland Piedmont park, or If no state-operated ozone monitoring station can provide good estimates for the park, monitoring on the park is preformed using a Portable Ozone Monitoring Station. In late sumer, conduct ozone injury surveys at two CUPN parks per year. For any remaining parks, if data from the nearby state-operated ozone monitor or the Portable Ozone Monitoring Station suggests that ozone-sensitive plants may be experiencing ozone injury, that park or the CUPN may conduct an ozone injury survey in late summer.	Management Applications Data on ozone levels and ozone injury assessment data are used to determine whether select species of park vegetation are being damaged by elevated ozone levels. This information is used for New Source Review, in the review of Prevention of Significant Deterioration of air quality permit applications.
