Biota-Sediment Accumulation Factors (BSAFs) for Per- and Polyfluorinated Substances (PFAS)
Science
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.

Developing an Exposure Burden Score for Chemical Mixtures Using Item Response Theory, with Applications to PFAS Mixtures
Science
2 Nov 2022 | Environ Health Perspect
A novel exposure burden score method for chemical mixtures was developed and applied to estimate the exposure burden of PFAS mixtures and resulted in stronger estimated associations with cardio-metabolic outcomes in the general U.S. population compared to summed PFAS concentrations.
