The textural and mineralogical characteristics of the dust fallout along with the potential effect on human health were investigated at 12 locations in Kuwait City and suburbs during March 2006-February 2007. Mineralogically, the dust comprises mostly calcite and quartz with grain size ranging from 1 to 25 lm. Chemically, elements such as Ca, Fe, Mg, and Al are the dominant ones with the highest amount of average percentage concentration 12.89% for Ca. Results showed that humans in the 12 sites are being exposed to different ranges of average percentage concentrations of minerals such as calcite (15.00-51.80%), quartz (26.40-66.9%), albite (6.30-17.30%), dolomite (1.20-10.20%), and gypsum (0.00-6.4%), where site K3 recorded the lowest average concentrations for calcite, dolomite, and gypsum and the highest for quartz, and albite.
