Air pollution in Santiago (Chile) as studied by nuclear and other techniques. Appendix 6

The elemental characterization of the urban aerosol in Santiago and of a rural area using different non-destructive analytical techniques such as PIXE, NAA and XRF was performed. In addition, AAS was used for selected samples and intercomparison purposes. The distribution of selected elements on membrane filters was studied using XRF. To assure adequate quality of the analytical data, an analytical quality control exercise was planned and carried out. Furthermore, different analytical techniques were used for the determination of the same elements in the same sample as further quality control procedure. (author)
