Title Volatile organic contaminants found in the habitable environment of the space shuttle: STS-26 to STS-55
Bibliographic information Sep. 1994, Vol.65, No.9, Section I, p.851-857. Illus. 20 ref.
Abstract Analysis of spacecraft respirable air during 28 space shuttle missions indicated that the major contaminants were relatively nontoxic alcohols, ketones, alkanes, halocarbons and siloxanes. Occasionally more toxic contaminants such as methanol, acetaldehyde and tetrachloroethene were present at low concentrations. Toxicity assessments showed that air quality was consistently in line with current guidelines. While the usual airborne load of volatile organic contaminants poses little risk to crew health, accidental contamination of the air, especially through pyrolysis of polymeric material, is a recurring problem.
