Poultry litter is used on land as fertilizer; other litter disposal methods include combustion, anaerobic digestion, and composting. The litter is also dried and used as cattle feed. Little information is available on the emission of organic gases on drying poultry litter. In this study we report the emission (and identification with a gas chromatograph- mass spectrophotometer – GC/MS) of gases on drying (20 – 110C) poultry litter. The gas-chromatograms with a quality-match of over 90% with the NIST MS Library are included. A number of aldehydes (benzaldehyde, hexanal, nonanal, octanal), sulfur compounds (dimethyl disulfide, dimethyl trisulfide), ketones (2-decanone, 2-heptanone, 2-nonanone), alkanes (tridecane, hexadecane, nonadecene), 2-butyl-pyridine and 2-pentyl-furan were identified. The emission of these gases has also been reported from swine and mussel operations; these gases are flavoring agents and are non-toxic.
