"Indeed such compounds do not have a half life. They can only continue to increase in concentration in everyone’s body over time" Wrong. https://www.foodandwaterwatch.org/insight/these-chemicals-are-forever-water-contamination-pfoa-pfos-and-other-pfas https://www.foodandwaterwatch.org/insight/these-chemicals-ar... "PFASs can concentrate in the bodies of humans and animals over time through a process known as bioaccumulation. For example, as a result of PFOA’s tendency to bioaccumulate and its long half-life in humans, PFOA’s presence in the body can persist even after exposure stops. PFOA’s half-life (the length of time it takes for a substance to decrease to half of its original value) in humans is anywhere from over two to nearly four years, while other PFASs have been shown to have a half-life of over eight years. There is also evidence that some PFASs can biomagnify, or increase in concentration, up the food chain."
