Do we really know how to decide what is safe? Are assumptions on the “data” we use to declare something safe or not valid?

Check out this article in C&EN on “How to Define Safe Water”:

We have to check and re-check the assumptions we make when we make “scientific” declarations.  Bisphenol-A:  is it or isn’t it the cause of every adverse effect (including obesity) just because we can detect minute levels?  I don’t know.  Let the arguments continue – but make sure the best science is being done and reviewed.  Don’t let the uninformed emotion or administrative ease be the only basis for “the answer.”

PS – check out for great blogs on risk perception.
