Two methods for the collection of ambient organic vapors at the ng/m/sup 3/ to ..mu..g/m/sup 3/ level were utilized in field sampling at a residential site in Portland, OR, during the winter and spring of 1983. The methods were adsorption/solvent extraction with polyurethane foam plugs (ASE/PUFP) and adsorption/thermal desorption with Tenax-GC cartridges (ATD/Tenax-GC). ASE/PUFP was used with a single sample flow rate in a single channel of the sampler. ATD/Tenax-GC was used with two different sample flow rates in two separate channels. Each method was found to be well suited to the analysis of compounds in a specific range of volatility. Some intermediate-volatility compounds were determined with all three sampling channels. The coefficients of variation for the three channels pooled over seven events were 9-36% for compounds in the range of volatility between acenaphthene and pyrene. The low sample volumes used with ATD/Tenax-GC for determinations at the ng/m/sup 3/ level make it an attractive method for many applications.
