| Abstract: | The chemical analysis of urban Toronto airborne particulate matter (PM), size segregated into respirable PM10/2.5, is presented.
The characterization of PM by use of proton-induced X-ray emission analysis (PIXE), and inductively coupled plasma-atomic
emission spectrometry revealed elemental information; a newer laser ablationionization mass spectrometry approach has the
potential to expand the chemical information from PM by analyzing both the inorganic and organic species. These PM analytical
approaches will be continued in the future for studying (1) emission source identification, (2) inhalation health hazards,
and (3) urban smog chemistry. |
