Quackery springs eternal! As if bloodletting was not dismissed long ago! What a laughable article! However, this study was published in the prestigious Journal of the American Medical Association!
Why would you even consider donating supposedly toxic blood for use in transfusions to other recipients? This study is a little bizarre!
Those poor 185 Australian firefighters that were the guinea pigs of this clinical trial!
"... That being said, PFAS are known to be potentially carcinogenic, and exposure to PFAS has been associated with “low fetal weight, impaired immune response, thyroid function abnormalities, obesity, increased lipid levels, liver function alterations, and, potentially, an increased risk of some malignant neoplasms ...
So far, the team says that these substances are already “ubiquitous” and that “no threshold has been identified that poses an increased risk to recipients of donated blood components”. In other words, potential recipients are overwhelmingly likely to already harbor some PFAS in their bloodstream and we don’t have any data to suggest that receiving blood contaminated with the compounds exposes them to any additional risks. ..."

From the abstract:
"Importance Elevated levels of blood perfluoroalkyl and polyfluoroalkyl substances (PFASs) have been associated with a range of adverse health outcomes. Firefighters have been exposed to PFASs in firefighting foams and have previously been shown to have higher PFAS levels in blood samples than the general population. No interventions have been shown to reduce PFAS levels.
Objective To examine the effect of blood or plasma donations on PFAS levels in firefighters in Australia. ...
Analysis between groups indicated that plasma donation had a larger treatment effect than blood donation, but both were significantly more efficacious than observation in reducing PFAS levels.
Conclusions and Relevance Plasma and blood donations caused greater reductions in serum PFAS levels than observation alone over a 12-month period. Further research is needed to evaluate the clinical implications of these findings."
