![]() Ketones, indoles, phenols, nitrogen-containing compounds, sulfurcontaining compounds, and other compounds (Schiffman et al.,Ģ001). Volatile organic compounds identified in and around swine operations can be classified into different chemical groups including acids,Īlcohols, aldehydes, amines, volatile fatty acids (VFAs), hydrocarbons, Related to swine manure and swine operations is presented in Table 1. Comparison of sampling locations, methods, and VOCs That has been published with 324 compounds being tentatively List of VOCs and fixed gases in air around swine production facilities Recognition and identification of odorous VOCs from swine manure. (1997) and Clanton and Schmidt (2000) have also reported Odorous compounds were identified by Kai and Schafer (2004). In the research conducted by Yasuhara et al. More than 30 VOCs were identifiedĪs being responsible for malodor in fresh and rotten swine manure Schaefer (1977) identified 20 VOCsįrom liquid swine manure. Of studies have attempted to determine the relationship between A number of studies have been conducted to identifyĬompounds emitted from swine manure. Is microbial degradation in the anaerobic environment of manure Groups have investigated odor emissions from swine operations Including NH3, H2S, and methane (NRC, 2003). Organic compounds (VOCs), particulate matter, and other gases Wine operations are sources of aerial emissions of odors, volatile Without permission in writing from the publisher.

Known had an estimated atmospheric lifetime <24 h.Ĭopyright © 2008 by the American Society of Agronomy, Crop Science The compounds for which reaction rates with OH Seventy one compounds had a distinct odor. With molecular weights ranging from 34 to 260 were identified. Odor impact of separated compounds was evaluated by a trained The isolation, separation, and identification of compounds. With a system of valves allowing transfer of samples betweenĬolumns (heartcutting). MDGC-MS-O system was equipped with two columns in series Polydimethylsiloxane (PDMS) 85-μm SPME fibers. Were extracted from manure headspace using Carboxen/ Phase microextraction (SPME) and novel multidimensional gasĬhromatography–mass spectrometry–olfactometry (MDGCMS-O) system were used to simultaneously identify VOCsĪnd related odors emitted from swine manure. Organic compounds (VOCs) and other gases that can affectĪir quality on local and regional scales. Swine manure is associated with emissions of odor, volatile Jenks, and Hongwei Xin Iowa State University Multidimensional Gas Chromatography–Mass Spectrometry–Olfactometry Simultaneous Chemical and Sensory Characterization of Volatile Organic Compounds and SemiVolatile Organic Compounds Emitted from Swine Manure using Solid Phase Microextraction and
