Assessing the risk of foliar injury from ozone on vegetation in parks in the Northern Great Plains Network
2004. Assessing the risk of foliar injury from ozone on vegetation in parks in the Northern Great Plains Network
This introduction provides an overview of the risk assessment process and the data used. The risk assessment is based on a Triad model that holds that the response of a plant to ozone is the result of the interaction of the plant, the level of exposure and the exposure environment. While interactions among the three variables determine the response, the state of any one of them can serve to accentuate or preclude the production of foliar injury. The response is greatest when all three variables and their interactions are optimized relative to the conditions that foster injury. The optimized states are: the species of plants are highly sensitive to ozone, the exposure levels of ozone significantly exceed the thresholds for foliar injury, and the environmental conditions foster gas exchange and the uptake of ozone by plants.
