Roem，Melia Azedarach L.和Woodfordia Floribunda（L.）Kurz的均匀尺寸，年龄，蔓延和常见于公路两侧发生的研究。在今年的三个主要季节（下雨，冬季和夏季）估计所选植物叶片上的尘埃积累。从道路两侧从两个水平距离（0-5米和5-10米）收集样品。结果表明，叶片上的尘埃积聚在G. Optiva中的0.0083g m-2中的0.0083g m-2〜0.0597g m-2，并遵循下降阶G. Optiva> W.Floribunda> M.Azedarach> T.Ciliata。季节智慧被检查的植物物种随后冬季下降冬季>夏季>雨季。 Plants grown at a distance of 0-5 m accumulated higher dust on their leaves as compared to 5-10 m distance from the road. Due to surface characteristics of twigs, bark and foliage of the plants particulate matters are captured by them and remain there for extended time period. From the results of this study, it could be inferred that the air quality in urban/ arid areas can be improved by planting firstly the species G. optiva and W. floribunda along road sides of similar highways to national highway-22.
