PFAS are special here because they are quite hard to get rid of. The C-F bond is the most resistant that chemistry can produce, it is very hard to destroy. They are also very hard to excrete from the body: half-life of PFOA (the oldest PFAS) in your blood is several years. As a consequence, the accumulate in the environment and in living organisms, including human beings.

Firefighters in this study are mildly contaminated (lucky them!). 95th percentile for PFOA in this study is 3.30 g/L. In France, the Esteban study reported 95th percentile for PFOA at 5.257 g/L. This is the general population, not firefighters.
