RE: dioxin and hcb in ferric chloride

["Catalano, Dennis" <catalad@wdni.com>]

What are the units for the 0.162 TEQ?  If someone has money and the sample,
our lab would be glad to try to analyze this stuff.  I have never had the
opportunity to analyze this type of material, but if it is being added to
vitamins, it might be something that we should investigate.
