| Abstract | A number of potentially toxic trace metal and organic species have been shown to be preferentially enriched on the surfaces of most types of anthropogenic particles which are emitted to the atmosphere. The use of several surface analytical techniques including ion microprobe mass spectrometry, Auger electron spectrometry, electron spectrometry for chemical analysis (ESCA), and time resolved solvent leaching for the study of such particles is discussed. Results are evaluated in terms of the information they provide about the processes of particle formation and transformation and about potential environmental impacts. In addition, the strengths and weaknesses of the different techniques are compared with emphasis on those directly related to particle surface analysis.
