Part of the concern for those living in highly contaminated areas is that PFAS chemicals persist in bodies, dropping by half in blood serum only after a period of years — if exposure falls. If high PFAS levels in the immediate environment keep exposure elevated, the chemicals accumulate faster than the body can excrete them — raising risks of many associated health problems (see graphic). PFAS cross the placenta and enter breast milk so mothers risk passing the compounds they have accumulated on to their children.
