Gypsum in animal slurry systems enhances generation of hydrogen sulphide and increases occupational exposure hazard.


Hydrogen sulphide gas (H2S) produced by sulphate reducing bacteria (SRB) in stored animal slurry is highly toxic and, if emitted into poorly ventilated confined spaces, can build up to concentrations capable of causing asphyxiation. Therefore it is important to understand factors influencing H2S emission from slurry. Powdered gypsum (hydrated calcium… (More)
