1.1 This part of ISO 15202 specifies a number of suitable methods for preparing test solutions from samples

of airborne particulate matter collected using the method specified in ISO 152021, for subsequent determination

of metals and metalloids by ICPAES using the method specified in ISO 152023. It contains information about

the applicability of the methods with respect to the measurement of metals and metalloids for which limit values

have been set. The methods can also be used in the measurement of some metals and metalloids for which limit

values have not been set but no information about its applicability is provided in this case.

NOTE The sample preparation methods described in this part of ISO 15202 are generally suitable for use with

analytical techniques other than ICPAES, e.g. atomic absorption spectrometry (AAS) by ISO 8518[5] and ISO 11174[10]

and inductively coupled plasma mass spectrometry (ICPMS) by ISO 30011[11].

1.2 The method specified in Annex B is applicable when making measurements for comparison with limit

values for soluble metal or metalloid compounds.

1.3 One or more of the sample dissolution methods specified in Annexes C through H are applicable when making

measurements for comparison with limit values for total metals and metalloids and their compounds. Information on

the applicability of individual methods is given in the scope of the annex in which the method is specified.

1.4 The following is a non-exclusive list of metals and metalloids for which limit values have been set (see

References [15] and [16]) and for which one or more of the sample dissolution methods specified in this part of

ISO 15202 are applicable. However, there is no information available on the effectiveness of any of the specified

sample dissolution methods for those elements in italics.

Aluminium Calcium Magnesium Selenium Tungsten

Antimony Chromium Manganese Silver Uranium

Arsenic Cobalt Mercury Sodium Vanadium

Barium Copper Molybdenum Strontium Yttrium

Beryllium Hafnium Nickel Tantalum Zinc

Bismuth Indium Phosphorus Tellurium Zirconium

Boron Iron Platinum Thallium

Caesium Lead Potassium Tin

Cadmium Lithium Rhodium Titanium

ISO 15202 is not applicable to the determination of elemental mercury or arsenic trioxide, since mercury

vapour and arsenic trioxide vapour are not collected using the sampling method specified in ISO 152021.
