Technical Abstract: Three methods of extracting volatile organic compounds (VOC's) adsorbed on the airborne dust in a swine finishing building were investigated. Airborne dust was collected in pre-baked glass fiber filters (GFF's) and the compounds were extracted by solvent extraction using dichloromethane, solid phase microextraction (SPME) using carboxen/polydimethylsiloxane (CAR/PDMS) and PDMS fibers, and purge and trap methods. Solvent extraction was not sensitive enough to extract detectable amounts of compounds, except for some high boiling point fatty acids. The SPME and purge and trap methods were effective in extracting the more volatile compounds adsorbed in the airborne dust. The SPME CAR/PDMS fiber extracted the low to mid boiling point compounds like the fatty acids, phenols and indoles, while the PDMS fiber extracted more of the mid boiling point compounds, specifically the aliphatic hydrocarbons. Purge and trap method extracted compounds with low to mid boiling points. Most of these compounds are also present in the air of swine buildings. The major compounds identified were carboxylic acids, aldehydes, alcohols, ketones, hydrocarbons, phenols, indoles, phthalates, and esters.
