Dust is considered as one of the atmospheric phenomena that inappropriately influences the environment. Falling dust contains particles with the size of 100 microns or less, which falls from atmosphere on the surface of the earth. This study aimed at determining the Pb concentration in falling dust samples in order to investigate the urban pollution caused by this element. To investigate the quantitative changes in falling dust lead and its spatial analysis, sampling was performed using 30 sediment traps for 3 months in the winter of 2014. These traps were installed in 30 stations on the roofs of some buildings in Zahedan which were about 1.5 meters high. As the results indicated the Cumulative average of lead concentration was 97.32±5.4 mg/kg in the winter. Correspondingly, scrutinizing lead zoning map revealed that the lowest lead level was measured at the Azadegan station in the winter, whilst the Behdasht station received the highest lead level.
