Mineral dust particles are considered one of the most important types of aerosols in the atmosphere which can be lifted to high altitudes and transported widely. It can mix with polluted air masses during transport and become coated with soluble chemical substance. Thereby, it can contribute to the radiative forcing and the precipitation formation. For this article, we have collected airborne Saharan dust by gravitational settling on a clean surface during sand storms events over Egypt on spring 2010 on 10 May the sample of mineral particles was taken from Port said, Dabaa, Elarish, 6 October, Aburdees and Kaha Cities. We collected six samples of airborne mineral dust which had been carried by the winds from the Sahara desert to sampling different points which are located and analyzed by Ion chromatography. It was found that the airborne Saharan dust samples had accumulated soluble coatings during transport by interaction with air pollutants. Cation and Anion are (Na+, NH+4 , K+, Ca2+, Li+ , Mg2+, No-2 , No-3 , Cl- , Br-, F-, SO2-4) on May 2010. Possible source regions of airborne mineral dust particles were determined by using the air mass back - trajectories model and the aerosol optical depth (AOD) through Deep Blue AOD in the range 550 nm.
