P2017-RT

Per- and polyfluoroalkyl substances like PFOA and PFOS

PFOA and PFOS are compounds of the group of per- and polyfluroalkyl substances (PFASs). Due to the widespread use of PFASs and due to accumulation as a consequence of the persistency of the compounds, food can be contaminated with PFASs. The CONTAM Panel of EFSA established new values related to the tolerable weekly intake (TWI) of PFOA and PFOS in 2018. TWIs are 6 ng/kg bw per week related to PFOA and 13 ng/kg bw per week related to PFOS.

P2017-RT is focused on the quantification of selected PFASs in liver.

Parameters within the scope of P2017-RT are:

  • Perfluorobutanoic acid (PFBA)
  • Perfluoropentanoic acid (PFPeA)
  • Perfluorohexanoic acid (PFHxA)
  • Perfluorohepanoic acid (PFHpA)
  • Perfluorooctanoic acid (PFOA)
  • Perfluorononanoic acid (PFNA)
  • Perfluorodencanoic acid (PFDA)
  • Perfluorobutane sulfonic acid (PFBS)
  • Perfluorohexane sulfonic acid (PFHxS)
  • Perfluorooctane sulfonic acid (PFOS)

A homogenised liver, spiked with the parameters mentioned above is provided as test material. The corresponding unspiked homogenised liver is available as blank material.
