As an individual, you can donate blood regularly. There was a study done that found that repeated whole blood or plasma donations were both effective at reducing PFAS levels over time.
It never occurred to me that blood removal would be an effective method, but there is a certain logic to it. Although it also seems like you'd have to do it an awful number of times to make a difference.
I don't know, I'm definitely no expert in this area, and haven't looked for any similar studies for other toxins, so I'm not sure if other similar research has been done.
