Elemental analysis of size-segregated particulate samples for three rural Utah sites is presented and discussed. Daily samples were collected at each site in three size ranges (15-3.5 m, 3.5-0.5 m, 3.5-0.5 m, and 0.5-0.1 m) for a period of one year. Sulfur is shown to be important in the two smaller size ranges. There is no distinctive seasonal pattern in sulfur concentrations. Overall, the mass contribution of the soil related components to ambient particles is greatest. Soil related elements dominate in the two larger size ranges and are significant (amounting to about 50%) in the smallest size range. The soils show a distinctive seasonal variation with winter concentrations, about a factor of three smaller during the summer. Small particle soils may be a significant cause of visibility degradation.
