title: [Volatile metabolites in expired air of humans during 5-day dry immersion].
abstract: Both gas chromatography and mass-spectrometry were used to analyze make-up of air expired by 7 human subjects in a dry immersion (DI) experiment simulating some of the effects of microgravity. It was found that 5-d DI produces significant increases in expired amines, chiefly butylamine, 2-cyanacetimide, some aldehydes (isobutyl aldehyde, benzaldehyde), polyols (ethylene glycol, butyldiol), phenol, phenyl acetylene, ketones (methyl-ethyl-ketone), butylacetate and a significant decrease in fatty acids.
