Abstract
The most important fraction of aerosols with respect to human health i s the respirable fraction, which has particles less than 10 mu m in eq uivalent aerodynamic diameter (EAD), the so called PM10 fraction. The collection of these respirable particles and the determination of thei r trace element composition is the focus of an IAEA Go-ordinated Resea rch Programme (CRP). ?he IAEA Laboratory participated in this Programm e and established collection sites for the air particulate samples on the grounds of the Atominstitute of the Austrian Universities in Vienn a and the IAEA Laboratories, Seibersdorf, representing an urban reside ntial site and a rural site. The collected samples as well as samples of simulated air filters (used also for blind controls) and control ma terials were analyzed sequentially and/or in sections by X-ray fluores cence (XRF), proton induced X-ray emission (PIXE), instrumental neutro n activation analysis (INAA), and atomic absorption spectrometry (AAS) . Results demonstrate the applicability of the PM-10 sampling approach , provided PIXE and/or. INAA are used in the determinations. Reliable results can be obtained that will lead in comparable air pollution dat a for many regions in the world through CRP.
