Interpretive Summary:

Technical Abstract: Reduced sulfur compounds are emitted from waste handling at animal agriculture operations. These sulfur compounds are responsible for odor production as well as participating in atmospheric chemistry. We have adapted a chromatographic method for providing 10 minute online monitoring capability of reduced sulfur compounds. Field testing of the instrument has taken place at a swine facility that composts waste under the house and at a poultry processing facility that uses an anaerobic lagoon to generate methane for recycled energy use. Atmospheric concentrations of sulfur compounds at the swine facility show bursts of ambient concentrations upon mixing of compost. Not all sulfur compounds have the same temporal profiles with dimethyldisulfide peaking at the low ppb level several hours after mixing. At the poultry processing facility, high concentrations of hydrogen sulfide generated by the lagoon were caused corrosion of surrounding buildings and potential problems with the generator. Condensation traps were utilized to reduce sulfur from the gas phase (air) and convert into the liquid phase.
