The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go. So H2 and CH4 pass from the anus but these gases are also transported by the blood to the lungs and removed to the atmosphere.
Several factors affect gas formation: 1 amount and kind of fermentable substrate; 2 abundance, types, and location of microflora; and 3 psychic and somatic conditions that affect the gut.
We evaluated the first factor by studying men fed different diets and have also recorded influences of uncontrollable factors. One group of 6 men ate Gemini-type diet S and another received a bland formula F , for 42 days.
Breath and rectal gases were analyzed during the first and final weeks. Flatus gases varied widely within dietary groups but much more gas was generated with diet S than with F. In the first hour collection, subjects fed S passed 3 to ml ATAP of rectal H2 avg 52 and 24 to ml avg 69 from the lungs assuming normal pulmonary ventilation.
With F, these values were 0 to 3 ml avg 1 and 6 to 36 ml avg Subjects were calmer during the second test. Gas production was lower with S than initially; F values were unchanged. Methane differed idiosyncratically, presumably due to differences in flora. Computed from hour values, maximum potential daily H2 and CH4 are per man: for S, ml and ml; for F, 80 and ml. Volumes would be larger at reduced spacecraft and suit pressures. Register or Log In.
The Magazine Shop. The suits are also made of a synthetic fabric which allows some air movement. I never smelled myself, though there was one time that a coworker sitting about fifteen feet away heard me over the noise of the air handlers and machinery and laughed. Interesting but not quite what I meant by isolation suits. I am talking about these types of suits where a person is isolated from the room they are working in. Hold your nose. No…wait… Nevermind.
Wow that was pretty crappy coding on my part, here is the link. According to clean room rules, you get to rip another for the benefit of fellow employees, but only after removing the suit.
