Dust is an atmospheric phenomenon that has a negative impact on the environment. Less noticed, the dust particles cause respiratory and cardiovascular health problems in the citizens of western and southern regions of Iran. One of the actions could be to plant trees that are compatible with the climate of these regions. To investigate the role of woody plants in identifying and controlling dust centers, the leaves of four tree species (Albizia lebbeck, Eucalyptus camaldulensis, Conocarpus erectus and Cordia myxa) were sampled in four regions representing 9 geographical directions (center, main and secondary regions) in Ahvaz city, Iran. Leaf area and dust concentration were spatially analyzed in the laboratory for three seasons, i.e., spring, summer and autumn 2021. The Inverse Distance Weighted (IDW) interpolation method was used to map pollution. The results showed that C. erectus and C. myxa had the highest dust binding efficiency with average values of 1.066 and 0.976 mg/cm2, respectively, followed by A. lebbeck and E. camaldulensis with average values of 0.290 and 0.478 mg/cm2, respectively. The results of dust distribution zones showed that domestic dust sources were significantly high in the southwestern and southeastern regions with average values of 1.880 and 0.869 mg/cm2, respectively. Planting trees such as C. erectus, A. lebbeck and C. myxa in urban environments was suggested as an efficient method for dust control in the region
