[Dioxin-l] Re:Reply

[Tony Tweedale]

Some posts from these people have been logical, others not.  A couple days
ago one asked us to assume PVC (~50% of Cl use, and climbing) is a social
need; a 'must have'.  This assumption was quietely made, and followed by
the presumed main argument about controlling incinerator emissions.  People
have got to recognize bad logic!  Other posts from these people have
similarly been couched in reasonable sounding arguments but were actually
quite radical arguments--eg that dioxin in the env is safe if at a certain
level, or that drinking water disinfectn w/ Cl is another irreducible need
for Cl.  Other radical points have also been made that don't come to mind.
This is disingenious.  Always question assumptions.

BTW, on the disinfection q., I posted a short p'graph in a post on another
subject, so not all may have seen it.  Cities as Cincinatti and many others
use filtration and perhaps ozone.  O3 is a much more powerful oxidant than
Cl, and giardia cysts do not resist it the way they do Cl.  Residual
disinfection through to the point of use could be accomplished w/ far far
less Cl, if any, depending on the desire to manage risk and think.

Does anyone know hy so many dugs are compounded w/ HCl, and why this is
such a critical use of Cl (tho an infinitesmal one)?
