A laboratory study and two field studies were performed to evaluate the application of the Volatile Organic Sampling Train (VOST, EPA Method 0030) to the volatile halogenated organic compounds (approximately 35 compounds) listed in the Clean Air Act Amendments (CAAA) of 1990. Subsequently, a laboratory study was performed to assess the feasibility of the application of the VOST methodology to the volatile nonhalogenated organic compounds listed in the CAAA (approximately 20 compounds). Several of the volatile organic compounds were eliminated from consideration as VOST analytes because they could not be analyzed successfully by gas chromatography/mass spectrometry (GC/MS), and others were eliminated because of poor analytical system response. The remaining CAAA volatile organic analytes (benzene, toluene, carbon disulfide, 2,2,4-trimethylpentane, and hexane) were tested in the field using the guidance of EPA Method 301 for experimental design and statistical evaluation of the data. Quadruple VOST trains were run in the field, with dynamic spiking of the volatile analytes from a certified cylinder into two of the sampling trains. The bias and precision of the VOST sampling and analytical methodology applied to each of the volatile organic analytes were evaluated. 8 refs., 1 fig., 3 tabs.
