In the Eastern United States, hourly ambient concentrations of ozone typically range from 30 to 50 part per billion, with events that may exceed 100ppb. Typical exposure levels can cause visible foliar injury to some plant species and have the potential to reduce tree growth by up to 10 percent per year, depending on species and environment.
