| Significance and Use | |||||

5.1 Polycyclic aromatic hydrocarbons (PAH) as defined by this test method are compounds made up of two or more fused aromatic rings. 5.2 Several PAH are considered to be probable human carcinogens. 5.3 PAH are emitted in the atmosphere primarily through wood or fossil fuel combustion. 5.4 Two- and three-ring PAH are typically present in urban air at concentrations ranging from 10 to several hundred nanograms per cubic metre (ng/m3); those with four or more rings are usually found at concentrations of a few ng/m3 or lower. 5.5 PAH span a broad spectrum of
vapor pressures (for example, from 1.1 × 10–2 kPa for
naphthalene to 2 × 10–13 kPa for coronene at 25°C).

5.5.1 The distribution between
phases depends on ambient temperature, humidity, types and
concentrations of PAH and particulate matter, and residence time in
the air. PAH, especially those having vapor pressures above
10–8 kPa, may vaporize from particulate filters during
sampling. Consequently, a back-up vapor trap must be used for
efficient sampling.
5.6 Separate analyses of the filter and vapor trap will not reflect the original atmospheric phase distributions and should be discouraged.
1.1 This test method2 specifies sampling, cleanup, and analysis procedures for the determination of polycyclic aromatic hydrocarbons (PAH) in ambient air.
1.2 This test method is designed to collect both gas-phase and particulate-phase PAH and to determine them collectively.
1.3 This test method is a high-volume sampling (100 to 250 L/min) method capable of detecting PAH at sub-nanograms per cubic metre (ng/m3) concentrations with sampling volumes up to 350 m3 of air.
1.4 This test method has been validated for sampling periods up to 24 h.
1.5 Precision and bias under normal conditions can be expected to be ±35 to 50 %.
1.6 This test method describes a sampling and analysis procedure for PAH that involves collection from air on a combination fine-particle filter and sorbent trap and subsequent analysis by gas chromatography/mass spectrometry (GC/MS).
1.7 The range of this test method is approximately 0.05 to 1000 ng/m3 of air sampled.
1.8 The values stated in SI units shall be regarded as standard.
1.9 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.
