RE: dioxin and hcb in ferric chloride

[Jamie Harvie <Jamie.Harvie@WLSSD.Duluth.MN.US>]

I have only seen a reference to a  German study (Heindl and Hutzinger
1986) that found 0.162 TEQ TCDD/F  in ferric. I have not seen the study
to know what the derivation of the ferric was. In talking to our US
manufacturers it seems the majority is from reprocessed pickle liquour.
I did sample for HCB and found 41 ppb. Very frightening if your
pre-natal vitamin exposure holds up. I will contiue to pursue. None of
the folks I spoke to sampled for dioxin/f but I will if I can't get any
info.\

Any data on

		I was told once by a processor of pickle liquor in
Michigan from this 
		type of process that precipitated ferric chloride (they
		use refridgeration of pickle liquor to get it to
precipitate 
		out of solution) is not only used as a feedstock for 
		magnetic media manufacture but also as a feedstock for
		human vitamin/mineral supplements as ferric chloride 
		addition.   This means it might also end up as ferric
chloride
		supplements typically taken by pregnant women as 
		a pre-natal supplement.

		Is there firm information on TCDD/F TEQ equivalent
content of 
		pickle liquor and ferric chloride derived from this
source??
