Outside the Safe Operating Space of a New Planetary Boundary for Per-and Polyfluoroalkyl Substances (PFAS)
Science
2 Aug 2022 | ES&T
PFAS have been detected at unsafe levels in rain globally, leading to the conclusions that the spread of PFOS, PFOA, PFHxS, and PFNA in the atmosphere has exceeded levels of concern for chemical pollution and that PFAS uses and emissions should be rapidly restricted.

Effect of Plasma and Blood Donations on Levels of Perfluoroalkyl and Polyfluoroalkyl Substances in Firefighters in Australia: A Randomized Clinical Trial
Science
12 Apr 2022 | JAMA Netw Open
Regular blood or plasma donations result in a significant reduction in serum PFAS levels for participant firefighters with a baseline PFOS level of 5 ng/mL or more; plasma donations reduced levels more quickly than blood donations.
