Feces titanium

In a very recent study, van Wijnen et al ( ) reported the results of a study of 2-4 year old children wherein the feces were analyzed for titanium, aluminum, and acid soluble residue (air). The results showed that the data were approximately normally distributed. Estimates of 105 mg/day for nursery school children and 49 mg/day for the hospitalized children were obtained. Even with the limited number of samples In the study (n = 24), the difference between the two populations was significant (p < 0.01). If the value for the hospitalized... 

Animals and humans excrete the majority of ingested titanium via the feces (Table 24.5). Feces of cattle contained 50 to 365 mg kg DM (Tblgyesi and Nagy 1990). Fecal excretion of ingested titanium amounted to 85% or less in non-lactating women with a mixed diet, to 74-83% in ovo-lacto-vegetari-ans, and to 70% or less in nursing women.
