[Analysis of the trace contaminants in the atmosphere formed by the life-support environment of the closed system of man-higher plants-lower plants-microorganisms].
Trace contaminants in the air of a biological life support system which was continuously complicated were examined. Air samples were taken by cooled traps and analyzed by gas chromatography. Changes in the air of the biological life support system as a function of its structure were compared using Hamming distance and composition similarity measures. Matrices of the measures were obtained and a graph whose structure corresponded to changes in the biological life support system was constructed. During prolonged experiments trace contaminants remained relatively stable and changed when a mineralization component was attached. It is concluded that the composition and variations in the organic components of the atmosphere can be used as an integral indicator of the function of the biological life support system as a whole.
