AbstractGases other than formaldehyde and hydrocarbons emitted by seven samples of four makes of urea formaldehyde foam insulation (UFFI) have been sampled, identified, and their concentrations estimated. Results by capillary column gas chromatography/mass spectrometry (GC/MS) of 80 degrees C head space UFFI gases are compared to results by atmospheric pressure chemical ionization tandem mass spectrometry (APCI/ MS/MS) of UFFI gases purged at 23 degrees C. Estimates of the reproducibility of the two apparatus at the test conditions were made. Twenty components of UFFI gases from these foams were identified and their concentrations estimated by GC/MS. Twenty-two were identified and the concentration of twelve estimated by APCI/MS/MS. Seven were common to both. Results are compared to threshold limit values, or their estimates in order to select the gases that should be monitored in houses and to define the required range and sensitivity for such methods. In both sets of measurements, acetic acid, dioxane, ethylene glycol, and methyl furfural were found in quantities that approached or exceeded a TLV/100 or 0.01 TLV that was established as a ` benchmark' or reference level. The APCI measurements also indicated that acetaldehyde and formic acid were of similar concentrations. The GC/MS results indicated that at a higher temperature, dibutylphthalate, dichlorobenzene, 2- furyl methanol, and naphthalene emitted in quantities that exceed their respective reference concentrations by factors of between 5 and 240. Common household gases appeared to have been stored on UFFI and to be released during tests.
