Description:
The availability of reliable, accurate and precise monitoring methods for to:':ic volatile organic compounds (VOCs) is a primary need for state and local agencies addressing daily monitoring requirements related to odor complaints, fugitive emissions, and trend monitoring. The canister-based monitoring method for VOCs is a viable and widely-used approach that is based on research and evaluation performed over the past several years. his activity has involved the testing of sample stability of VOCs in canisters and the design of time integrative samplers. he development of procedures for analysis of samples in canisters, including the procedure for VOC preconcentration from whole air, the treatment of water vapor in the sample, and the selection of an appropriate analytical finish has been necessary. he canister-based method was initially summarized in the EPA Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air as Method TO-14. odifications and refinements are being added to the Method TO-14 in order to obtain a Scope of Work for the Superfund Contract Laboratory Program for Air. This paper discusses the developments leading to the current status of the canister-based method and provides a critique of the method using results obtained in EPA monitoring networks.
