Description / Abstract:
This part of ISO 15202 specifies a method for collecting samples
of airborne particulate matter for subsequent determination of
metals and metalloids using inductively coupled plasma — atomic
emission spectrometry (ICP-AES). Samples obtained using the method
described herein can also be subsequently analysed for elemental
composition by other instrumental methods, such as atomic
absorption spectrometry (AAS) or inductively coupled plasma mass
spectrometry (ICP-MS).
The method is not applicable to the sampling of mercury, which
is present in air in the vapour phase at ambient temperatures;
inorganic compounds of metals and metalloids that are permanent
gases, e.g. arsine (AsH3); or inorganic compounds of
metals and metalloids that are present in the vapour phase at
ambient temperatures, e.g. arsenic trioxide
(As2O3).
NOTE Although the method does not describe a means of collecting
inorganic compounds of metals and metalloids that are present in
the vapour phase, in most instances this is relatively easily
achieved by using a back-up filter which has been pre-treated to
trap the compound(s) of interest, e.g. a back-up paper pad
impregnated with sodium carbonate is suitable for collecting
arsenic trioxide (see ISO 11041[2]).
The method is applicable to personal sampling of the inhalable
or respirable fraction of airborne particles, as defined in ISO
7708, and to static sampling.
