Are there any non-health related problems associated with ozone?
High ozone levels can damage leaves on trees and crops, reducing growth rates and crop yields. Ground-level ozone damages plant life and is responsible for $500 million dollars in reduced crop production in the United States each year. Q: What is an Ozone Action Day? A: An Ozone Action Day occurs when ozone levels are forecasted to be a Code Orange, Red or Purple. On these days, ozone concentrations are predicted to exceed the proposed federal standard of 0.08 parts per million averaged over an 8-hour period. When the NCDAQ expects ground-level ozone concentrations to reach or exceed the standard in one of the forecast areas, a forecast for an Ozone Action Day is issued, indicating the expected color code as well as the numerical AQI value.
