Possible Interaction: Fluorides and Iron, Dietary

“In addition, a combination of iron and fluoride reduced the incidence of dental caries in our rats.”

“The presence of iron and vitamins affect the bioavailability of fluoride as measured by the area under the time-plasma fluoride concentration curve.”

“Since a similar phenomenon has been previously observed with respect to the fluoride concentration … the same fishes (Suga et al., 1981a), it is speculated that the concentrations of iron … fluoride , which have originally no chemical correlation, have some special biological … and distribution pattern of their deposition are completely different.”

“The extraction of lead is based on the complexing properties of ethylenediaminetetra‐acetic acid (EDTA), the iron being masked with fluoride ions.”

“Except for beryllium to some extent, combinations of cadmium, cobalt, iron , manganese, tin and zinc with fluoride were not as effective as aluminium in inhibiting the ATPase activity.”

“Strikingly, soils of similar depth and horizonation from the same soil order but … soil series exhibited markedly different susceptibility to Al loss in the presence of fluoride , possibly a combined result of differences in the mechanism … sorption, soil mineralogy, reactivity of the surficial Al and Fe , and soil … chemistry.”

“The most serious interference is from iron ; this can be prevented by adding fluoride or pyrophosphate.”
