Abstract: The study was conducted during the period from March 2017 to February 2018 at three locations rural, urban and industrial to monitoring deposition of dust on monthly basis in Kerbala, Iraq. The results of this study revealed that the rate of dust falling ranged 9.66-96.04 g/m2 with average 36.47 g/m2 in the rural and areas industrial, respectively. The morphological analysis of dust using the scanning electron microscope showed that the dust particles are not homogeneous, particularly the urban area, most of which are of different and irregular shapes and the sizes of dust particles ranged from 13.22-30.80 μm. The 16 elements in dust were found using energy dispersive x-ray analysis five of them were heavy metals (Cu, Cr, Ni, Cd and Pb). X-ray diffraction analysis showed that calcite (42.6%) and quartz (26.1%) were the dominant minerals in the dust. It appears from the collection and analysis of the results that the sites of study have a significant effect on the concentration, shapes, sizes and contents of dust particles.
