PFAS exposures in childhood are negatively associated with overall bone mass density, with the strongest association seen for PFNA amongst 5-year-olds.
Biota-Sediment Accumulation Factors (BSAFs) for Per- and Polyfluorinated Substances (PFAS)
18 Nov 2022 | Environ Toxicol Chem
A summary of biota-sediment accumulation factors is given for many PFAS, and the largest research gap identified is understanding the effects of concentration and mixtures upon bioaccumulation from sediments.
First Evidence of Prenatal Exposure to Emerging Poly- and Perfluoroalkyl Substances Associated with E-Waste Dismantling: Chemical Structure-Based Placental Transfer and Health Risks
18 Nov 2022 | Environ Sci Technol
Electronic waste dismantling contributes to adult and fetal exposure to PFAS, with 6:2 FTSA, 6:2 Cl-PFESA, and PFOPA identified as major emerging PFAS with trans-placemental transfer efficiencies higher than that of PFOS.
