Abstract
Inhalable airborne Particulate Matter (PM) has been linked to adverse effects in
the airways and cardiovascular system in humans leading indirectly to
hospitalization and possibly premature death. The need to monitor these on a
local level has recently been realized with the emergence of low cost tabletop
Scanning Electron Microscopes (SEM) with high magnification possibilities
offering a quick and easy way of analyzing PM down to 300 nanometres in size.
The ease of use of these instruments makes them suitable for an untrained person
to routinely monitor elemental constituents of individual particles and possibly
linking them to inherent health risks. In this study particles from outdoor air
were collected onto Polyamide filters and analyzed using tabletop SEM utilizing
Energy Dispersive Spectroscopy (EDS) to determine and identify their chemical
composition. 341 particles were successfully characterized and classified in
relation to their chemical identity and origin. The regional differences in the
samples could be related to the location of sample collection proving that
tabletop SEMs offers a possibility of air quality monitoring in relation to the
particle impurities.
