ISO 15202-1:2012 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). 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.

<p> La méthode n'est pas applicable à l'échantillonnage du mercure, qui est présent dans l'air en phase vapeur aux températures ambiantes, des composés inorganiques de métaux et métalloïdes qui sont des gaz permanents, tel l'arsine (AsH3) ou des composés inorganiques de métaux et métalloïdes qui sont présents en phase vapeur aux températures ambiantes, tel le trioxyde d'arsenic (AS2O3) -NOTE: Bien que la méthode ne décrive pas de mode opératoire de collecte de composés inorganiques de métaux et métalloïdes présents en phase vapeur, dans la plupart des cas ceci est relativement facile à effectuer en utilisant un tampon de support qui a été pré-traité pour capter le(s) composé(s) intéressant(s), tampon en papier imprégné de carbonate de sodium par exemple pour recueillir le trioxyde d'arsenic (voir ISO 11041).La méthode est applicable à l'échantillonnage individuel pour la fraction inhalable ou alvéolaire de particules en suspension dans l'air, selon la définition de l'ISO 7708, et à l'échantillonnage à point fixe. </p>
<p>This document 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).</p> <p>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 (AsH<sub>3</sub>); or inorganic compounds of metals and metalloids that are present in the vapour phase at ambient temperatures, e.g. arsenic trioxide (As<sub>2</sub>O<sub>3</sub>).</p> <p>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 to achieve 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<sup>[2]</sup>).</p> <p>The method is applicable to personal sampling of the inhalable, thoracic or respirable fraction of airborne particles, as defined in ISO 7708, and to static sampling.</p> <p>This document excludes sampling of surfaces or bulk materials.
