[Composition of the water obtained after its sanitary and hygienic use by men and women].

The composition of wash water used by men and women was investigated. The results were exposed to multifactorial statistical analysis using the method of principal components. The investigation allowed the following conclusions to be made: 1) wash water used by men and women is comparable in composition; therefore the sex of the crewmembers of space vehicles can be disregarded when designing water reclamation systems; 2) three parameters, viz. oxidizability, electric conductivity and chloride content, can be adequately used to assess the quality of utilized wash water; 3) the composition of wash water is largely dependent on the health status of its users.
