摘要: Abstract Trace chemical contaminants generated by human metabolism is a major source of contamination in spacecraft crew module. In this research, types and generation rates pollutants from were determined the Chinese diets. Expired air, skin gas, sweat 20 subjects analyzed at different exercise states simulated The designed according to basic activities orbit astronauts. Qualitative quantitative analyses metabolic performed with gas chromatography/mass spectrometry, chromatography UV spectrophotometer. Sixteen compounds sources found. With increase physical load, concentrations expired air correspondingly increased. species offgassing are among Chinese, Americans Russians due differences ethnicity dietary customs. This research provides data aid design, development operation China's long duration space mission.
