A. The use of Ammonium sulphide is highly relevant to ostomy output simulation: when exposed to air it hydrolyzes and produces hydrogen sulphide and ammonia which gives the rotten egg smell . Suarez et al (GUT 1999) found that malodour (in flatus) significantly correlated with hydrogen sulphide concentration. They also concluded that sulphur containing gases are the major, but not only, malodorous component of human flatus.
