Sulfur Hexafluoride as a Surrogate for Volatilization of Organics from Indoor Water Uses

Degradation of indoor air quality by potentially toxic volatile organic chemicals is of growing concern. It has been shown that the use of contaminated potable water indoors, such as in showers and baths, can release these chemicals and cause inhalation exposures to the inhabitants that may be substantially higher than those from the direct ingestion of that water. In this paper, they describe a system for delivering controlled concentrations of SF/sub 6/ into water devices and present initial results of SF/sub 6/ volatilization studies with a full-size shower.
