Under anaerobic conditions, organic compounds containing sulfur break down, forming intermediate sulfur-containing compounds that ultimately form hydrogen sulfide. The objectives of this project were to determine various sulfur-containing compound concentrations in collected air and liquid samples from stored swine and dairy manure and correlate these sulfur compound concentrations with each other. Three different manure-handling/storage methods (a batch study, a semi-batch study, and a field study) generated a total of 52 paired (air and liquid) samples. Of the 20 sulfur-containing compounds detectable by the analytical laboratory, six were detected in the air samples and seven were detected in the liquid samples. None of the compounds was significantly affected by specie (swine and dairy). Concentrations of hydrogen sulfide, dimethyl sulfide, and carbon disulfide changed significantly with time. Additional research is needed to further examine the biochemical pathways in the formation of hydrogen sulfide from anaerobically stored manure.
