In recent years, different aspects of dust storm, as one of the environmental problems, have been investigated by many researchers. One of the main goals in this regard is controlling of the dust and its subsequent hazards. The first step in the controlling process of dust or its hazards is detection of dust as well as determination of dust concentration. There are different methods and devices to determine dust concentration. In the present article, the presence methods and devices to measure the dust concentration in the environment have been presented and explained. Also, the potential application of image processing technique as a low cost method to determine dust concentration has been discussed.
