The Dilemma of Perfluorooctanoate (PFOA) Human Half-life
Science
25 Aug 2021 | Regul Toxicol Pharmacol
Based on information from both human observational studies and clinical data, we proposed a range for the half-life for PFOA of 0.5 to 1.5 years, which would likely raise many existing regulatory safe levels if all other parameters stayed the same.
