Although soil erosion is associated with hazardous conditions in any form, the range of soil particles that can move in suspension or saltation in the air is very important in dust-related issues. In other words, regardless of erosion and its problems, familiarity with these particles and providing solutions to reduce their adverse effects can be very useful. In this study, which focused on dust sources in the southeast of the city of Ahvaz in Iran, 57 samples were tested in the dry state in a wind tunnel, and then concentrations of the produced dust were evaluated in four wind regimes. The results indicated that an exponential function (C = 6 × V3) was established between the wind velocity in the wind tunnel and concentrations of dust obtained from soil samples. In this function, C and V respectively represent the dust concentration in mg m−3 (6 cm above soil surface) and wind speed in meter per second (10 cm above soil surface). It was also found that the dust concentration has a direct relationship with sodium adsorption ratio, and with an increase in the sodium adsorption ratio of the soils, the dust concentration increases with a linear relationship (C = 54.147(SAR) + 23,107).
