From page 9...
... Several hundred chemical contaminants are likely to be found in the closed-Ioop atmos there and recycled water of the space station. In 1992, the NRC provided NASA with guidelines for developing exposure guidance levels for airborne contaminants in Guidelines for Developing Spacecraft Maximum AZZowabZe Concentrations (SMACs)

From page 10...
... The 1-day SWEG is a concentration of a substance in water that is judged to be acceptable for the performance of specific tasks during rare emergency conditions lasting for periods up to 24 hours. The 1day SWEG is intended to prevent irreversible harm and degradation in crew performance.
