Optimizing the Paks Method for Measuring Airborne Acrolein

Abstract: Airborne acrolein is produced from the combustion of fuel and tobacco and is of concern due to its potential for respiratory tract irritation and other adverse health effects. Active sampling with DNPH-coated solid sorbents has been widely used for sampling airborne carbonyls; however, it is not suitable for sampling acrolein. The Passive Aldehydes and Ketones Sampler (PAKS) is a diffusive, tube-type sampler, which utilizes a dansylhydrazine (DNSH)-coated silica-based bonded C18 sorbent to collect airborne carbonyls. The original PAKS method has been shown to have a collection efficiency of >60% and improved sample stability for acrolein, compared to the DNPH method. However, it is desirable to further increase the PAKS acrolein collection efficiency and improve sample stability.

This work has been funded in part by the US EPA under PO#2D-5806-NAEX. It has been subjected to Agency review and approved for publication.
