Evaluation of the Importance of Some East Asian Tree Species for Refinement of Air Quality by Estimating Air Pollution Tolerance Index, Anticipated Performance Index, and Air Pollutant Uptake

摘要: Potentials of tree species as biofilters depend on appropriate selection based their tolerance to air pollution, which is usually evaluated by the pollution index (APTI) and anticipated performance (API). Thus, these values need a means scientific understanding assess role urban trees for better greenspace planning/management mitigate impacts gaseous such ozone (O3) sulfur dioxide (SO2). O3 exposure Chionanthus retusus, Pinus densiflora, Ginkgo biloba showed higher stomatal flux than others, finally resulting in both favoring movement maintaining carbon fixation. In contrast, despite whole enhanced SO2 uptake under excess exposure, assimilation capacity was only found Taxus cuspidata Zelkova serrata consequence no sluggishness. On basis API, P. densiflora Prunus × yedoensis were good performers developing greenspace, while Z. G. moderate performers; however, C. retusus T. estimated be poor very performers, respectively, reducing quality injury caused pollutants. The present study suggests that an integration APTI API absorption needed selecting sound tree-species planning/construction control pollutions.
