Characteristics of dust deposited along a transect between central Iran and the Zagros Mountains

Auteur(s) et Affiliation(s)



Description :
The aim of this study was to identify the variations in physical, chemical, and mineralogical composition of dust particles deposited along an elevational transect lying between central Iran and the Zagros Mountains in the west. Dust samples were collected at 12 localities during September 2008 and July 2009 with and without transboundary dust storms, respectively. The findings, together with satellite images and patterns of wind frequency and direction, clearly indicate the major contribution of a transboundary dust storm, probably originating from iraqi arid land, to atmospheric deposition in the Zagros area and central Iran. If dust storms originating from outside the country continue to occur, not only will they influence the surface soil properties in the Zagros region but will also induce environmental problems in the region.
