Krebs*, K A., V R. De Jesus*, V. de Jesus, M A. Mason*, AND X. Liu. SOURCE CHARACTERIZATION OF AIR FRESHENERS. Presented at Indoor Air Quality Problems and Engineering Solutions Symposium, Research Triangle Park, NC, July 21 - 23, 2003.
Description:
The paper discusses research in which five air fresheners of two styles were analyzed for their constituent volatile organic compounds. Both styles were refills to be inserted into heated electric plug-in units; one refill released the fragrance from a gel pack insert and the other from a wick/liquid reservoir insert. The analysis followed the protocol of EPA Method 311. Data are presented identifying specific compounds and concentrations in the air freshener inserts. Identifications were made using gas chromatography/mass spectrometry with authentic standards or mass-spectral library search routines. The prominent compounds include limonene, a-pinene, b-pinene, and camphene. One of these air fresheners was selected for emissions testing in the EPA's large chamber facility. Weight loss data for individual compounds obtained from analysis of the air fresheners before and after testing are presented.
