Abstract

Methods have been developed to sample and quantitate vapor-phase nitrogen heterocyclic bases in ambient air. A high-volume sampling procedure which employs Florisil as an adsorbent is used to trap azaarenes. The analytical procedure provides simple and reproducible determinations of trace levels of the two- and three-ringed nitrogen-containing compounds. The procedure involves carefully controlled evaporative concentration of eluates from Florisil and a ″mini″ acid - base extraction. The data obtained from the analysis of ambient air indicate that vapor-phase levels of azaarenes are many times higher than those previously reported based only on particulate matter.
