US EPA publishes final toxicity assessment for GenX chemicals

Sets maximum daily intake limit of 3 ng/kg body weight/day for hexafluoropropylene oxide (HFPO) dimer acid and its ammonium salt; final value is much lower than first suggested in earlier 2018 draft assessment, also lower than set reference dose for the hazardous chemical PFOA it was developed to safely replace
