Abstract :In this study, atmospheric dust samples were collected via Partisol 2025 ID device working in EPA mode by using PM10 insert ignore into journalissuearticles values(Particulate matter less than 10 microns); filter during 2016-2017 from Sanliurfa, Turkey. The arrival direction and source detection of atmospheric dust was determined by the MODIS satellite view and HYSPLIT model. The structure of the samples was characterized by XRD insert ignore into journalissuearticles values(X-Ray Diffraction);, SEM insert ignore into journalissuearticles values(Scanning Electron Microscopy); combined with EDX insert ignore into journalissuearticles values(Energy Dispersive X-ray); and FTIR insert ignore into journalissuearticles values(Fourier Transformed Infrared Spectrum);. Results show that the major phases observed in the XRD spectrum of the samples are calcite, dolomite, gibbsite, anorthite, and sodium borate hydroxide. The compositions of dust samples were found to be Ca, Si, Al, Na, and Mg in a higher ratio than other elements via SEM-EDX analysis. Further, this study reveals the variability of PM morphological and elemental composition on different days at locations and highlighted the different probable sources associated with them.
