The purpose of this study was to compare the amount of dust deposited on the leaves surface of Fraxinus rotundifolia, Platanus orientalis, and Robinia pseudoacacia in urban areas of Kermanshah Province, west of Iran. Kermanshah, Ravansar, and Paveh regions with different climatic features were selected for sampling. Leaf samples were randomly collected from different heights of individual trees in four main directions and washed and dust particles of the solution were dried in an oven and weighed. The leaf area was measured by Image J software. The results indicated that the amount of dust per unit leaf area of P.orientalis (0.10 mg.cm-2) was significantly different with those of F.rotundifolia (0.045 mg.cm-2) and R.pseudoacacia (0.04 mg.cm-2) (F=66.703). Significant difference was observed between the amount of deposited dusts in Paveh (0.087 mg.cm-2) (F=16.624) and those of the other sites (Kermanshah: 0.041 mg.cm-2and Ravansar 0.053 mg.cm-2). The results of this study will open up an avenue for identifying suitable trees for dust filtration in the west of Iran. Biological activities are underlyingstrategies against dust storms. The leaves, because of the larger surface in comparison with other parts of plant organs, are considered important for atmospheric dust filtration.
