ABSTRACT
The irritating, sensitizing, and toxic effect of water produced by the method of carbon dioxide hydration was examined in animal experiments and human observations. It was found that before and after decontamination this water did not cause skin irritation or organism sensitization, did not have a toxic effect on the CNS, liver, kidneys or blood morphology, and did not deteriorate adaptive capabilities of the animal or human body.

Influence of electrolysis gaseous oxygen (EGO) mixed with nitrogen (1:4) on the living organism was studied in a 30-day 24-hour experiment on guinea pigs. A preliminary conclusion states, that EGO, obtained in the system with a solid polymeric electrolyte out of moist materials of different chemical composition, can be recommended for the formation of artificial gas atmosphere in hermetic objects in the mixture with gaseous nitrogen in the ratio 1:4.

The authors evaluated the problems of hygienic aspects of oxygen obtained by the method of electrolytic decomposition of water with a different content of chemical substances in the system with a hard polymere electrolyte. On the basis of sanitary-chemical qualities and toxicological properties electrolysis gaseous oxygen may be recommended for use in creating an artificial gaseous atmosphere in hermetically sealed compartments in mixture with gaseous nitrogen (ratio 1:4).

It has been shown that gaseous oxygen produced in a system containing a solid polymer electrolyte from distilled water and two water samples containing different concentrations of chemicals meets on the whole USSR Standard 5583-78 and iso standard 2046. This oxygen underwent toxic evaluations on 60 white noninbred male rats. When mixed with gaseous nitrogen (1:4), electrolytically produced oxygen exerted no unfavorable effects on the animals.
