Abstract
  • This project was initiated to find a practical way of identifying the volatiles and monitoring their relative concentrations. Special attention was given to the identification of the organic acids. Volatile compounds produced in a swine confinement building were trapped by porous polymers, Porapak Ω and Tenax GC, and identified by combined gas-liquid chromatography and mass spectrometry. GLC outputs were used as the basis for estimating concentrations. The odorous gases responsible for the nuisance are principally released during anaerobic and faculative decomposition of manure. The amines, mercaptans, sulfides, organic acids, and heterocyclic nitrogen compounds are generally regarded as being of greatest importance in odorous air. About 30 compounds were positively identified by the trap method, including the organic acids acetic, propionic, butyric, and valeric. The concentration of these acids was found to be in. the 10 ⁻⁶ μg/1 range.
