BLUNDEN, JESSICA. Characterization of Non-Methane Volatile Organic Compounds at Swine Facilities in Eastern North Carolina. (Under the direction of Dr. Viney P. Aneja)
 

Summary: ABSTRACT
BLUNDEN, JESSICA. Characterization of Non-Methane Volatile Organic Compounds
at Swine Facilities in Eastern North Carolina. (Under the direction of Dr. Viney P. Aneja)
A total of 110 samples of volatile organic compounds (VOCs) were collected and
analyzed in a field study to characterize such compounds emitted at six swine facilities in
Eastern North Carolina between April 2002 and March 2003 as part of the Project OPEN
(Odors, Pathogens, and Emissions of Nitrogen). Two baseline sites employed
conventional lagoon and field spray technologies while four sites utilized various
alternative "Environmentally Superior Technologies" (ESTs) in an effort to substantially
reduce gaseous compound emissions, odor, and pathogens from these swine facilities.
More than 200 compounds, including various paraffins, alkynes, aromatics, esters, ethers,
monoterpenes, alcohols, aldehydes, ketones, monoterpenes, halogenated hydrocarbons,
phenols, and sulfides were identified and quantified by Gas Chromatographic/Flame
Ionization Detection (GC/FID) analysis as well as confirmed and/or verified by Gas
Chromatographic/Mass Spectrometry (GC/MS). GC/MS analysis of three particularly
complex samples collected at one site assisted in providing identification and retention
times for more than 20 sulfur type volatile organic compounds (VOCs) including methyl
mercaptan, dimethyl sulfide, dimethyl disulfide, and dimethyl trisulfide as well as many
other VOCs. Carbonyl sulfide and carbon disulfide were positively identified by GC/MS
analysis but were not identified by GC/FID due to their particular compound
