Abstract |
The second field method evaluation test was conducted to validate the performance of a draft method for determining high concentrations (20-100 ppm) of phenol and the cresols in stationary source emissions. The draft method is based on a modification of the EPA Reference Method 5 sampling train with high performance liquid chromatography (HPLC) for analysis. The Method 5 train was modified by replacing the condensation trap and water impingers with three impingers containing 200 mL each of 2N NaOH solution. The modified train was tested in the laboratory and in a field method study at a fiberglass manufacturing plant. This second field tests was conducted at a phenol/formaldehyde resin manufacturing plant to demonstrate that the draft method is not industry-specific. The field test, designed according to the guidelines of EPA Method 301, used quadruple sampling trains with dynamic spiking in two of the trains. The statistical evaluation of the data showed no significant bias for phenol and o-cresol, but did show a significant bias with a correction factor of 1.04 (acceptable according to Method 301 criteria) for m-/p-cresol. Precision of spiked and unspiked trains was also acceptable according to Method 301. The results from the second field test are consistent with the results obtained from the first field test. |
