摘要: Abstract Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are detected in the environment and, more specifically, wildlife humans. The large variation reported biological half-lives for PFOA PFOS has remained unexplored. In this study, we aimed to evaluate their partition from serum bile cerebrospinal fluid (CSF) Four pairs of bile, 7 CSF were donated by patients. considering biliary excretion, median concentrations samples 3.8 23.2 ng/mL, respectively, whereas those 1.0 27.9 ng/mL, respectively. ratio (bile/serum: 0.60) was significantly higher than that PFOA, 0.21 (p
