[Hygienic evaluation of moisture and carbon dioxide absorbers recommended for purifying the atmosphere of hermetically sealed chambers].

This paper presents hygienic evaluation of carbon dioxide absorbers (zeolites KA-SM and M-11) and water absorbers (silica gel KCM-6B). It has been shown that these agents contain no toxic components, produce smell of no more than 1-2 scores at normal and high temperature, exert no stimulating effect on atmospheric microorganisms, and are safe for man. In view of this, the above absorbers can be used to purify an enclosed atmosphere.
