  • When is ozone damage most severe? Ozone damage accumulates over time will likely become worse throughout the growing season.
  • Do you see high ozone concentrations? Ozone concentrations typically peak during the afternoon and are considered unhealthy by the EPA above 70 ppb.
  • Do you see a connection between ozone concentrations and plant damage? Continual exposure to high daytime ozone concentrations (typically above 40 ppb) will contribute to visible damage on plant leaves.
  • Note: We cannot guarantee accuracy as AirNow data comes from several government agencies.
  • Ozone affects plants over long periods of time.
  • Try to look at long term changes instead of daily fluctuations.
