A comparison of methods for measuring hazardous air pollutants from lumber dry kilns

NCASI Methods 98.01 and 105 for measuring the emissions of hazardous air pollutants (HAPs) from lumber dry kilns were compared by taking 56 matched samples from kiln gas while several species were dried. Spike tests were also evaluated. Both
the direct comparisons and the spike tests indicate that Method 105 may provide lower values for formaldehyde emissions than Method 98.01. The values for methanol emissions were slightly lower for Method 105, but spike tests did not support a difference. The spike results for other HAPs are provided. The results should be of interest to facilities that are close to being a major source and to individuals needing to select a test method.
