New approach to derive PFAS limit values

The EU scientific committee SCHEER has approved a method to use relative potency factors to calculate limit values for human intake of PFASs.

According to a scientific opinion of 18 August 2022, the European Commission’s Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) has endorsed the use of Relative Potency Factors (RPF) of the individual PFASs to set total limit values for mixtures of PFAS substances.

The decision has resulted in a heated debate among scientists and researchers, as there is often little or no data when it comes to risk assessment of the impact of PFASs on the environment and human health. However, SCHEER maintains that the RPF approach is currently the best available method for setting quality standards for PFAS substances.
