Abstract :
Aim: Particulate matters are among the most important air pollutants in urban environment which cause heart and respiratory diseases. Plants play a major role in aerosol removal. In this study, some of important shrub species of urban green space were investigated for their ability of reducing air particulate matter pollutants.Material and Methods: In present study, effect of five shrub species (including privet, oleander, barberry, cotoneaster, Spindle tree), which most planted in Tehran city and their roles to aerosol sedimentation, was investigated. Therefore, leaf surface pollutants were collected and weighed and evaluated relative to the leaf surface. Results: The results showed that barberry collects pollutants more than other mentioned plants, while the efficiency of oleander is less than other species. Conclusion: It seems that the morphology of plant leaves is effective in pollutant absorption. In addition, the amount of aerosol in air can affect the efficiency and absorption of suspended particles.
