While it is still early days for this research, the feasibility of blood donation as a longterm, scalable solution is still questionable, as Lennquist explains: "For specifically exposed persons, like firefighters, it may be an option to empty the contaminated blood and let your body produce new blood. That requires that you will not be exposed again. For the average person the exposure is quite constant and I do not see that it could be a solution for the general population. But it definitely points to the urgency to do something about PFAS."
