1.1 This test method specifies a procedure for collection, sample preparation, and analysis of airborne particulate matter for the content of metals and metalloids using inductively coupled plasma-atomic emission spectrometry (ICP-AES).
1.2 The method is applicable to personal sampling of the inhalable or respirable fraction of airborne particles and to area sampling.
1.3 This method specifies a number of alternative methods for preparing test solutions from samples of airborne particulate matter. One of the specified sample preparation methods is applicable to the measurement of soluble metal or metalloid compounds. Other specified methods are applicable to the measurement of total metals and metalloids.
1.4 The following is a non-exclusive list of metals and metalloids for which one or more of the sample dissolution methods specified in this document is applicable. However, there is insufficient information available on the effectiveness of dissolution methods for those elements in italics.
1.5 The method is not applicable to the sampling of elemental mercury, or to inorganic compounds of metals and metalloids that are present in the gaseous or vapor state.
1.6 This test method contains notes that are explanatory and are not part of the mandatory requirements of the method.
1.7 The values stated in SI units are to be regarded as the standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
