Аннотация: Gas exchange between man and plants in a closed ecological system based on atmosphere regeneration by plant photosynthesis is made consistent by attaining the equilibrium of human CO2 discharge and the productivity of the gas consuming bioregenerator. In this case the gas exchange might be, however, qualitatively disturbed from the equilibrium in terms of oxygen making it accumulate or decrease continuously in the air of the system. Gas exchange equilibrium in terms of O2 was attained in long-term experiments by equality of the human respiration coefficient and the plant assimilation coefficient. Varying the ratio of these parameters it is possible to control the oxygen concentration in the atmosphere to be reclaimed.

Man as a component of a closed ecological life support system / J. I. Gitelson, U - Okladnikov YuN // Life support & biosphere science : international journal of earth space. - 1994. - Vol. 1, Is. 2. - P73-81 . - ISSN 1069-9422

Аннотация: Material support of all manned space flights so far has been provided from a prestored stock of substances or replenished from the Earth's biosphere. Exploration of space will, however, become real only when man is able to break away from Earth completely, when he will be accompanied by a system providing everything necessary to sustain full-valued life for an unlimited time. The only known system to date meeting this requirement is the Earth's biosphere. To break away from his cradle, as K.E. Tsiolkovsky called Earth, it is necessary to devise a life support system functionally similar to the natural biosphere. This need not be similar in structure to the vast diversity of trophic relationships available on Earth, but requires the solution of a multitude of various problems of an ecological, physiological, engineering and social-psychological nature. Human life-support systems based on biological regeneration of environments in small volumes have been studied at the Institute of Biophysics (Siberian Branch of the Russian Academy of Sciences) over many years. This work has resulted in the design of Bios-3, a biologically-based self-sustained human life support system.
