Hydrogen sulfide gas is one of hundreds of known odor-producing compounds emitted from livestock facilities. The smell of hydrogen sulfide is best described as a "rotten egg" smell. Hydrogen sulfide gas is heavier than air and tends to be in highest concentrations at the surface of manure storage containments. However, unlike other gases produced in livestock operations, it can be deadly if high concentrations (more than 100,000 parts per billion) are present. Generally, this only occurs when anaerobic deep pits beneath swine confinement buildings are agitated during manure removal and adequate ventilation is not provided. Low levels of hydrogen sulfide can cause ...
