Forum: Heavy metal content and dioxin in comercial binders
Published:December 14, 2009
By:Dr O’Flannegan
Good day, Lately many binders like bentonites are being banned around the world. The organic binders have not experimented changes for the last 8 years, its absorption in Aflatoxin and Zea is good, contrary with T2 and other mycotoxins. Aluminosilicates present ambivalent results concerning dioxin and heavy metal contamination, which make absorption more difficult, cause they occupy the place where this process is developed. Clinoptilolite-Heulandite zeolites contrast in these parameters, cause are heavy metal and dioxin free, and are authorized by the EU. Shouldn’t be off the market? Greetings Dr O’Flannegan
Not all clay based toxin binders conatin dioxin. If the mines are supervised properly, one can get superior clay based toxin binder at a very reasonable and affordable price as we manufacture at our facility.

Dr. O’Flannegan,
We are aware of no country that has banned bentonites for use in animal feed or human feed. Calcium and sodium bentonite binders are inorganic compounds and vary greatly in their purity and how they are processed – two factors which greatly affect their binding of different mycotoxins. Bentonite is authorized as a feed additive in the EU as E558, and like all feed additives are subject to maximum limits for undesirable substances such as dioxin and heavy metals.
There are nearly fifty different naturally-occurring zeolites known to exist. To suggest that each and every one is free of dioxin and heavy metals, regardless of where they are mined or how they are processed, is erroneous. Zeolites do not have “chemically active” binding sites such as bentonites and are used in many industries to physically trap contaminant molecules within their internal pores. These same pores could physically entrap dioxin and heavy metal molecules no different than the pores found in bentonites.
As long as minerals meet established safety regulations and provide value to end users, they should be on the market.
