Leaves infusion solutions were prepared to mimic rain or dew water on leaves. Ozone reaction rates of these solutions were measured with a denuder reactor. Wheat infusions showed higher reaction rates than beech, oak and pine infusions. Ascorbate, VOC and ozonolysis products were measured in senescing wheat infusions. Senescing leaves showed large reaction rates likely due to out-leaching compounds.
