dc.descriptionBecause of their vast surface distribution, external particle reactivity, and leaf characteristics, urban trees can contribute as biofilters, reducing PM pollution. Leaves of trees permit PM to be accumulated, depending on their leaf traits. The impacts of several leaf characteristics on PM accumulation capabilities, such as surface roughness and leaf morphology, have been studied. The change in relative humidity (RH) caused by leaf gas exchanges of urban trees also can be highly related to the removal efficiency of PM because the hygroscopic growth of particle is closely related to PM deposition. Nevertheless, the impacts of leaf gas exchange parameters including stomatal conductance and transpiration rate on PM deposition ability still remain unidentified. The effects of PM pollution on urban plants’ photosynthesis are also not well understood. In this study, we analyzed the correlation between PM accumulation and photosynthesis (Pn), stomatal conductance (gs) and transpiration (Tr) of all the tested urban trees under approximately 300 μg/m3 of fly ash emitted condition and evaluated the increased effect of leaf gas exchange parameters on PM deposition. We also studied whether the inhibiting impacts on the ability of leaf gas exchange is occurred by the blockage and closure of the stomata by using scanning electron microscopy (SEM). The purpose of our research was to better understand the interaction between particulate matter (PM) adsorption and leaf gas exchange characteristics of urban trees. Furthermore, the findings of this study can be used to provide scientific data about the suitability of tree species for urban forests.
