Perhaps I did not phrase the original question that well. The above formula
makes perfect sense, of course, but do you have any knowledge of estimates
or even guesstimates of the concentration of dioxin in toilet paper. I know
this depends on which brand, etc, but I was hoping that there might be some
info on non-chlorine paper, or chloinated paper somewhere.Thanks
