<p>This International Standard specifies sampling, cleanup and analysis procedures for the determination of polycyclic</p>
<p>aromatic hydrocarbons (PAH) in ambient air. It is designed to collect both gas-phase and particulate-phase PAH</p>

<p>This International Standard describes a procedure for sampling and analysis for PAH that involves collection from</p>
