| Abstract: | Scanning electron microscope energy dispersive X ray analysis system (SEM EDX) is able to provide analytical data for each single particle. Hundreds of particles are usually analyzed for an aerosol sample. Both physical and chemical characterization can be performed in terms of particle size and particle class compositional data, respectively. Mineral dusts such as aluminosilicates and quartz particles as well as sea salt particles featured coarse fractions. Fine fractions were dominated by various sulfur containing and carbonaceous particles. |
