Risk Report on Perfluorooctanesulfonate (PFOS) as a Component of Mist Suppressants in Chrome-Plating Tanks

摘要

Perfluorooctanesulfonate (PFOS) is a synthetic perfluorinated surfactant recently discovered to be ubiquitous in the environment. Animal data suggest a high tolerance for PFOS, as does epidemiological analysis of workers in PFOS manufacturing plants. A suggested reference dose of 0.02 mg/kg/day is presented. This constitutes an unlikely exposure level in the application of interest, as a component of mist suppressant in chromium plating tanks.
