Used the ratio of PFOS toxicity values between marine and freshwater as a surrogate for the ratio of PFOA toxicity values between marine and freshwater. This method is based on the data-bridging approach for aquatic toxicity (USEPA, 2010). • PFOS concentrations in effluents have been reported that approach indicative target values derived from available aquatic toxicity data. PFOA has been found to be weakly carcinogenic. This review shows the importance of the perfluoroalkylated substances for the environment and the necessity to fill the current gaps in knowledge of their environmental fate and effects.

In order to assess the adverse health effect potential of these chemicals, this research will characterize the reproductive and developmental toxicity of PFOS in laboratory rodent models; ascertain whether the toxic effects are dependent on the windows of exposure during development; construct a pharmacokinetic (PK) model for PFOS; elucidate the modes and/or mechanisms of actions for PFOS that 2021-04-08 · PFBS has been used as a replacement chemical for PFOS. PFOS is a chemical that was voluntarily phased out by the primary U.S. manufacturer by 2002. PFBS has been identified in environmental media and consumer products, including surface water, wastewater, drinking water, dust, carpeting and carpet cleaners, and floor wax.
