A 27-day experiment was conducted to determine mans contribution to trace contaminants in a sealed environment. An environmental test cell was maintained at a total pressure of 760 mm. Hg throughout the 27 days, with the first 13 days being unmanned and the last 14 days being manned. Four subjects were utilized during the 14-day manned portion of the test. During the 27 days, 97 compounds were identified and quantified 21 of these compounds were noted only during the manned portion of the study. Direct contaminant analysis of the sealed environment was not adequate for this type of comprehensive survey. Cryogenic fractionation and concentration, however, provided samples with sufficient concentration of contaminants for analysis by means of gas chromatography, infrared spectroscopy and mass spectroscopy. Carbon monoxide and carbon dioxide were compounds that were produced by man and identified in this experiment and that would require removal during the 14-day period.
