THE ATMOSPHERIC TRANSPORTED DESERT DUST OVER SANLIURFA (TURKEY) AND ITS STRUCTURAL PROPERTIES

In this study, atmospheric dust samples were collected via Partisol 2025 ID device working in EPA mode by using PM10 (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 (X-Ray Diffraction), SEM (Scanning Electron Microscopy) combined with EDX (Energy Dispersive X-ray) and FTIR (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.
