Dust storms in arid and semi-arid regions have harmful impacts on the environment, the economy, and the health of local and global communities. In this study, the frequency of annual dust events in twenty-five stations and five climatic variables including rainfall, maximum annual wind speed, average annual wind speed, maximum annual temperature, and average annual temperature in arid regions o...

 Background: The phenomenon of dust is a serious environmental problem in dry and semi dry regions. It has a destructive effect for the residents of such regions. Over two-thirds of Iran is in areas of dry and semi-dry climate conditions. Methods: In this research, dust fall measurements were taken in 41 stations across Yazd city using a marble dust collector (MDCO) located in diffe...

Extended Abstract Introduction: Dust storm is a major weather event that plays an important role in the Earth’s atmosphere and ocean surfaces. Dust storms affect marine phytoplankton, soil physical and chemical characteristics in entrainment and deposition areas, climate and radiative forcing, economic loss, and human health. They mostly originate from Introduction: Dust storm is a major weath...

Dust is one of the environmental problems in Kerman city. Due to the major aspect of mineralogy in environmental studies, mineralogy and chemical studies of dust in different regions of the city performed by microscopic thin sections, x ray diffraction (XRD) and ICP-MS. In all areas of the city, minerals such as calcite, quartz, feldspar, pyroxene, micas, Jaffeite, gismondine and clay mineral w...
