Any info on Fluoridated Dioxins & Furans?

[Mike Ewall <catalyst@envirolink.org>]

Anyone have info on whether dioxins and furans can be fluoridated?  Are the
produced in the same way (incineration)?  Would they still be refered to as
dioxins and furans?

If dioxins and furans are fluoridated rather than chlorinated, how does
their toxicity, persistance and bioaccumulation compare?

Are there as many toxic varieties of fluoridated dioxins and furans (and
perhaps biphenyls) as their are chlorinated varieties?

Any info on the sources of these chemicals?  

I'd imagine that some of the fluoridated pharmaceutical residues present in
human and non-human animal wastes would be a large source of these
chemicals if/when these wastes are burned.  Any insight on the prevalence
of halogens in pharmaceuticals (particularly in those fed to
factory-produced animals) would be appreciated.
