Abstract
The applicability of the Proton Induced X-Ray Emission (PIXE) technique to multi-elemental analysis of PM10 aerosol samples collected on Whatman 41 cellulose fibrous filters is investigated using concurrent samples collected on teflon membrane filters as references. The elemental levels measured on the two types of filter samples are highly correlated and the ratio of the elemental levels is related to the deepness of penetration of particles inside the filter, which is calculated from the Fan Filter Model. Therefore, PIXE analysis can be used to describe urban aerosol samples collected on low impurity level porous filters such as Whatman 41.
