Ground-level ozone and carbon dioxide – exposure and effects
Short description
Since several decades, we investigate effect of different gases on crops and forests, in particular elevated carbon dioxide concentrations and the regional air pollutant ground-level ozone. Earlier, much of the work was experimental, but now we focus on derivation of response functions and meta-analyses.
Crop quality and chemical composition of plant tissue under elevated carbon dioxide and ozone form important parts of our research. Another focus is the variation of air pollutants, in particular ozone, in time (influence by weather patterns such as heat waves) and space (small scale variation in relation to local climate and topography). Our research contributes to model development and risk assessment for ozone effects on vegetation, e.g. by contribution to the work of ICP Vegetation, an international programme investigating the impacts of air pollutants on crops and semi-natural vegetation associated with the Convention on Long-Range Transboundary Air Pollution (LRTAP).
