Workplace air — Determination of metals and metalloids in airborne particulate matter by inductively coupled plasma atomic emission spectrometry — Part 1: Sampling (ISO 15202-1:2020)
This document specifies a method for collecting samples of airborne particulate matter for subsequentdetermination of metals and metalloids using inductively coupled plasma — atomic emissionspectrometry (ICP-AES). Samples obtained using the method described herein can also be subsequentlyanalysed for elemental composition by other instrumental methods, such as atomic absorptionspectrometry (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 atambient 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 atambient temperatures, e.g. arsenic trioxide (As2O3).NOTE Although the method does not describe a means of collecting inorganic compounds of metals andmetalloids that are present in the vapour phase, in most instances this is relatively easily to achieve by usinga back-up filter which has been pre-treated to trap the compound(s) of interest, e.g. a back-up paper padimpregnated with sodium carbonate is suitable for collecting arsenic trioxide (see ISO 11041[2]).The method is applicable to personal sampling of the inhalable, thoracic or respirable fraction ofairborne particles, as defined in ISO 7708, and to static sampling.This document excludes sampling of surfaces or bulk materials. Guidance on collection of samples forsurfaces may be found in ASTM D7659[7].
