“…Therefore, stomatal uptake through stomata could possibly be influenced by drought stress, which the standard i-Tree Eco model neglects, assuming sufficient water availability or irrigation for the street and park trees. In fact, the stomatal closure has been shown to considerably reduce pollution removal in dry periods and alternative model formulations have been suggested [80,81]. Consequently, surface deposition was found to strongly depend on leaf structure [82,83], which determines both velocity and deposition capacity.…”

“…Mechanisms behind the chemical quenching at the soil surface are not completely understood but findings from several flux partitioning studies emphasized the soil as an important sink for O 3 in forests (Lamaud et al, 2002;Dorsey et al, 2004;Fares et al, 2014;Zhou et al, 2017) as well in ecosystems with smooth surfaces (Sanchez et al, 1997;Meszaros et al, 2009;Stella et al, 2013). The fact that low ground water levels favored O 3 uptake suggested that the depth or soil volume available for O 3 to diffuse in the soil pores constituted a limiting factor for uptake in the soil Vuolo et al, 2017).…”

“…At eCO 2 , stomatal conductance (Gs) is reduced, accompanied with an enhanced photosynthetic rate because plants do not need widely open stomata for getting CO 2 (Paoletti and Grulke, 2005;Fares et al, 2014). A reduction in Gs would decrease xylem sap flow via a reduced transpiration.…”
