Patterns of Elemental Excretion in Long Term Balance Studies

Systemic contact dermatitis after oral exposure to nickel: a review with a modified meta‐analysis

“…The doses used in the studies vary from 0.3 mg to 5.6 mg nickel (Table 1), while normal daily dietary nickel intake has been found to vary from 0.02 mg to 0.48 mg nickel (21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32). However, some studies have shown that an exposure dose equivalent to the maximal nickel exposure through the diet (0.9 mg nickel per day) (21) can induce systemic reactions in some nickel-sensitive individuals (6,8,9,13,20).…”

Baseline risk assessment of ground water contamination at the uranium mill tailings site near Durango, Colorado. Revision 1

“…Based on the geochemical models for the Durango site, all of the molybdenum exists in the form of well absorbable molybdate in ground water ('Tables 3.1 1 through 3.14). Human absorption rates of 40 to 70 percent have beon observed for the soluble forms of molybdenum (Tipton et al, 1969;Robinson et al, 1973;Alexander et al, 1974 …”

Baseline risk assessment of ground water contamination at the uranium mill tailings sites near Rifle, Colorado. Revision 1

“…Inorganic hexavalent forms such as molybdenum trioxide, sodium molybdate, and ammonium molybdate are readily absorbed from both food and water, whereas molybdenite is not. Human absorption rates of 40 t o 70 percent have been observed for the soluble forms of molybdenum (Tipton et al, 1969;Robinson et at., 1973;Alexander et at., 1974).…”

“…data (from three individuals) have suggested that as much as 10 percent of a repeated oral dose may be absorbed (Proescher et al, 191 7;Tipton et al, 1969). Soluble vanadium compounds that are inhaled and deposited are more …”
