Binding of Per- and Polyfluoroalkyl Substances (PFAS) to Serum Proteins: Implications for Toxicokinetics in Humans
Science
3 Jan 2024 | Environ Sci Technol
PFAS binding to major blood serum proteins is thought to affect toxicity, transport, and half-lives in the body. This study found shorter-chain PFAS showing a stronger binding to human serum albumin and longer-chain PFAS displaying a greater affinity for globulins, emphasizing the significance of understanding these interactions for more precise assessments of PFAS impact on human health in epidemiological studies.
