ICP Vegetation: Risk of ozone damage to ecosystems

 Risk of ozone damage to ecosystems low in arctic region  Risk highest in central Europe and parts of southern Europe, where

zone concentrations are higher and/or climate conditions

conducive to high ozone uptake by vegetation

POD = Phytotoxic Ozone Dose

Forest Grassland

ICP Vegetation: Global assessment of evidence of O3 damage to vegetation

Collating data on field evidence of visible leaf injury and beneficial effects of filtering

zone out of the air
