Abstract

Quantitative PIXE analysis was performed on several single aerosol particles collected with cascade impactor by the scanning proton microprobe of Debrecen. The cascade impactor samples were collected at an urban location in Debrecen and in a speleotherapeutic cave situated under Budapest during the winter of 1998. The aerosol samples have already been analysed by bulk PIXE technique. Elemental concentrations for 23 elements and also the size of the particles were determined. Cluster analysis was carried out to identify the different particle groups. The contribution of the different types of particles to each size fraction were investigated with special regard to the smaller size fractions which are interesting from the point of view of the speleotherapy. Traces of anthropogenic pollution were also shown in the cave aerosol, and the possible composition of particles containing these pollutants is given. Comparison of the urban and cave aerosol particles is also discussed.
