"That term does not refer to how long they stay in your body." I didn't assert that. I did state that after 70 years of only getting to some vague level of trace amounts its still likely there and that something of that nature is a "forever chemical" indeed. You haven't cancelled that. You do realise that PFOS actually does have a half-life when in the body and that the body does break them down? Slowly. My point is that even at 5.3 years or anything around that half-life the stuff is in your body. Basically forever... until you're likely very old or dead. You want to quibble about "forever" in a human being only 70 years. Ok. That's excessively pedantic however I'm not going to exhaustively iterate over every detail to do so. Your link is year-on-year PFOS concentrations. Seems that the exposure from the environment is increasing. Sure. How does that cancel out what I wrote? I fail to see where you've cancelled out my simulation at all. https://www.foodandwaterwatch.org/insight/these-chemicals-are-forever-water-contamination-pfoa-pfos-and-other-pfas https://www.foodandwaterwatch.org/insight/these-chemicals-ar...
