Using recent analytical data, the total body content of several trace elements for the 70 kg Reference Man has been reevaluated. The evaluation leads to the following conclusions. For Al, Ba, Cu and F, the present estimates show an increase; for Br, Cs, I, Pb and Zn the average values for the total body content derived from the present evaluation have remained close to the 1975 estimates; for As, Cd and Rb, the total contents have declined; for B, Co and Mn the uncertainty of the 1975 evaluations have been reduced; and for Au and Cr the 1997 estimations are far below the 1975 estimates. Provisional estimates for Ni (4–6.5 mg), Se (14–21 mg) and Si (2000–3000 mg) are proposed for the first time. With respect to dietary intakes, in contrast to the earlier estimates intakes of trace elements were found to be decreased by factors of 2 for Cu, 2–5 for Cr, 5–10 for Cd, Hg and Pb, and >10 for Ag, As, Co, Li, Sb and V.
