A laboratory study and three field studies were performed to evaluate the application of the SemiVOST (EPA sampling Method 0010, EPA sample preparation Draft Method 3542, and EPA analytical Method 8270) to the semivolatile halogenated organic compounds (approximately 80 compounds) listed in the Clean Air Act Amendments. A laboratory study was performed to assess the feasibility of the application of the SemiVOST methodology to the semivolatile nonhalogenated organic compounds listed in the CAAA (approximately 70 compounds). The remaining CAAA semivolatile organic analytes were grouped as acid/neutrals and base/neutrals and evaluated in the field using the guidance of EPA Method 301 for experimental design and statistical evaluation of the data. Quadruple SemiVOST trains were run in the field, with dynamic spiking of the semivolatile analytes from a methylene chloride solution of either acid/neutral or base/neutral compounds into two of the sampling trains. The bias and precision of the overall SemiVOST methodology (sampling, sample preparation, and analysis) applied to each of the semivolatile organic analytes were evaluated.
