This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 characteristics. The results of these samples were subsequently used as a source fingerprint to identify and/or verify these compounds in all other samples collected. Overall, the highest VOC concentration levels measured at each of the sites were in close proximity to the hog barns. The total measured VOCs at the hog barns were typically dominated by ethanol, methanol, acetaldehyde, and acetone. The combined overall contribution of these compounds in relation to total measured VOCs generally ranged from 46-94%. The highest concentration levels of both dimethyl.

Download or read book Simultaneous Chemical and Sensory Characterization of VOCs and Semi-VOCs Emitted from Swine Manure Using SPME and Multidimensional Gas Chromatography-mass Spectrometry-olfactometry System written by Yin-Cheung Miranda Lo and published by . This book was released on 2006 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swine operations are associated with emissions of odor, volatile organic compounds (VOCs) and other gases. One of the major sources of VOCs and odor is the manure. However, relatively little is known about VOCs and gases emitted and their relationship to the malodor. It is critical to characterize swine manure VOCs and malodorous gases to improve the understanding of the environmental impact of swine operations. This knowledge is also needed to develop and evaluate odor and gas emission strategies and technologies. In this research, solid phase microextraction (SPME) and multidimensional gas chromatography-mass spectrometry-olfactometry (MDGC-MS-O) system were used to identify VOCs and other gases emitted from swine manure. This analytical system enabled simultaneous chemical and sensory analyses of air samples. Manure was collected and transferred into individual vials in the laboratory. Gas samples were extracted from vial headspace using Carboxen/Polydimethylsiloxane (PDMS) 85 [Mu]m SPME fibers and were analyzed using the MDGC-MS-0 system. Twenty-four-hour SPME extractions were used to improve the detection limits for semi-volatile organics and compounds with small affinity to SPME fiber coating. The MDGC-MS-0 system was equipped with two columns in series with a system of valves allowing transfer of samples between columns (heartcutting). Thirty-second-wide heartcuts were used to maximize the isolation, separation and identification of compounds emitted from swine manure. The odor impact of separated compounds was evaluated by a trained panelist using the sniff port and Aromatrax odor characterization software. Odor was evaluated for character and intensity. A total of 295 compounds with molecular weights ranging from 34 (H2S) to 260 (1-chloro-hexadecane) were identified using analytical software BenchTop/PBM and MS ChemStation. One hundred and thirteen were positively confirmed with pure standards. Seventy one of the 295 compounds had a distinct odor/aroma and several had a strong impact on the characteristic swine odor. The correlations between compounds emitted from swine manure and their physicochemical properties were studied. Carbon number, boiling point, vapor pressure, water solubility, octanol-water partitioning coefficient (logK[subscript ow]), atmospheric lifetime ([Tau]) based on reactions with OH· radicals, gas-phase molecular diffusion coefficient (D[subscript g]), liquid-phase molecular diffusion coefficient (D1), Henry's law constant (H[subscript c]) and odor characteristics were summarized.

This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
