23 +This is just for fun.

25 +More than 99% of the volume of flatus is composed of non-smelly gases. These include oxygen (O,,2,,), nitrogen (N), carbon dioxide (CO,,2,,) hydrogen (H) and methane (CH,,4,,). Keep in mind, methane is a colorless, odorless gas and nitrogen is not produced in the gut, but it is a component of environmental air. The remaining trace (<1% volume) compounds give flatus its smell which comes from a combination of volatile sulfur compounds. Hydrogen sulfide (H,,2,,S), methyl mercaptan (CH,,4,,S), dimethyl sulfide (C,,2,,H,,6,,S), dimethyl disulfide (C,,2,,H,,6,,S,,2,,), and dimethyl trisulfide (C,,2,,H,,6,,S,,3,,).

31 +Hydrogen sulfide is a poison that affects nervous system the most. The toxicity of H2S is comparable with that of carbon monoxide as it binds with iron and it prevents cellular respiration.
32 +
33 +== ethyl mercaptan (CH,,4,,S)==
34 +
35 +It is a colorless but flammable gas with an extremely strong and repulsive smell (rotten egg). At very high concentrations it is highly toxic and affects the nervous system. It is used as an additive in natural gas in order to detect leakage.
36 +
37 +== dimethyl sulfide (C..2..H..6..S) ==
38 +
39 +It is flammable and an eye and skin irritant. It has an unpleasant odor at even extremely low concentrations.
