Kelly, T. AND M. Holdren. APPLICABILITY OF CANISTER SAMPLING FOR HAZARDOUS AIR POLLUTANTS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/A-94/239 (NTIS PB95155404).
Description:
The report evaluates the applicability of sampling with evacuated canisters for volatile organic compounds listed among the 189 Hazardous Air Pollutants (HAPS) in the 1990 US Clean Air Act Amendments. early 100 HAPs have sufficient vapor pressure to be considered volatile compounds. f those volatile organic HAPS, 52 have been tested previously for stability during storage in canisters. he published HAP stability studies are reviewed, illustrating that for nearly all of the 52 HAPs tested, canisters are an effective air sampling approach. owever, the published stability studies used a variety of canister types and test procedures, and generally considered only a few compounds in a very small set of canisters. omparison of chemical and physical properties of- the HAPs has been conducted, to evaluate the applicability of canister sampling for other HAPS, for which canister stability testing has haver been conducted. f 45 volatile HAPs never tested in canisters, this comparison identifies 9 for which canister sampling should be effective, and 17 for which canisters are not likely to be effective. or the other 19 HAPs,-,no clear decision ban be reached on the likely applicability of canister sampling.
