3 Apr 2021 | Environ Res

Pregnant women may be a group that is vulnerable to hypertensive disorders associated with PFAS exposures which should be considered by policymakers setting PFAS exposure limits.

The last straw: Characterization of per- and polyfluoroalkyl substances in commercially-available plant-based drinking straws

31 Mar 2021 | Chemosphere

The presence of 21 PFAS in plant-based drinking straws demonstrates that they are not fully biodegradable, contributing to the direct human ingestion of PFAS and to the cycle of PFAS between waste streams and the environment.

Sea turtles across the North Pacific are exposed to perfluoroalkyl substances

31 Mar 2021 | Environ Pollut
