Abstract
A sampling system was developed for collecting 20 significant probable or possible atmospheric carcinogens from ambient air. The sampling system is based on a combination of solid sorbent materials consisting of Tenax-GC, Porapak R, and Ambersorb XE-340 arranged in series. Air samples are drawn through this system using a Nutech Model 221-1A pump. The system was evaluated in sampling trips to Los Angeles, Niagara Falls, and Houston. The results for the analyses for the 20 selected compounds as well as additional broad-scan data are presented. Analyses of the samples were accomplished using thermal desorption of the sorbent materials followed by capillary column gas chromatography/mass spectrometry (GC/MS). A sample collected in Houston was also analyzed using a multi-detector capillary column GC system having a conventional flame ionization detector, a N-P flame ionization detector, a photoionization detector and an electron capture detector. A comparison of the GC/MS and multidetector GC results was made.
