In addition to the already known fixed gases, CO2, CO, H2S, NH3, CH4, etc., the environment within a confinement swine unit was found to contain a complex mixture of volatile organic intermediates. These intermediates are important in the characteristic odor resulting from the storage of manure and are suspected as being important in animal and building performance. Consideration of physical, as well as organic, biochemical phenomena indicated that the important intermediate products of anaerobic manure decomposition include organic acids, amines, amides, alcohols, carbonyls and sulfides. Qualitative chemical analysis confirmed the present of these homologous groups, except for organic acids that were decomposed upon formation by the high pH maintenance withinthe manure storage pit. To identify individual compounds within the swine environment, concentration of the volatile gases was required. Selective absorption, liquid salting and selective condensation were eachused in an effort to separate and concentrate the homologous series. Once separated, the series were subjected to chromatographic analysis for separation and identification. Table 1 summarizes the compounds isolated to date from the atmosphere within a swine unit. |
