Abstract:Ambient aerosol particles were studied by XPS (ESCA) and electron probe microanalysis energy‐dispersive X‐ray spectrometry (EPMA‐EDX) in a non‐destructive way. For sampling, polytetrafluoroethylene (PTFE) samplers were used in Battelle‐type cascade impactors.
Sampling locations and times were: Visonta (North Hungary), at a coal‐fired power plant at two sites, 23 September 1992; Debrecen city centre, in 3 h periods as a function of daytime, 11 November 1992.
From XPS the chemical states of the compounds of the … Show more
