Lists the biological role (now badly outdated) and abundance of each element in the Earth's crust, Atlantic and Pacific oceans, surface and deep, and the amount of every element in human muscle, bone and blood, plus average daily intake and total mass in average person.

Although the nearly 20 essential trace elements in humans constitute a small fraction of total body weight (less than 4%), the effect of their presence on well-being is enormous. Shinohara A.

Department of Food and Nutrition, Kyoto Women's University, Japan. Food Addit Contam - 1996 Oct;13(7):775-786. Daily dietary intake of 28 trace elements (Al, As, B, Ba, Be, Bi, Cd, Co, Cr, Cu, Ga, Ge, Li, Mg, Mn, Mo, Ni, Pb, Sb, Sc, Se, Si, Sn, Sr, Ti, Tl, V and Zn) were estimated from the food intake records, taking advantage of recently published trace element composition tables for foods in Japan.

"The estimated daily loss of trace elements from normal skin by desquamation." Scand J Clin Lab Invest - 1976 Nov;36(7):679-682 The content of 21 elements (As, Au, Br, Ca, Cd, Co, Cr, Cs, Cu, Fe, Hg, K, La, Mo, P, Rb, Sb, Sc, Se, W and Zn) in normal epidermis has been determined with the aid of neutron activation analysis. The dermal loss of these elements via desquamation [flaking off] has been calculated in view of its possible importance in balance studies. For some of the trace elements, however, the loss may be appreciable. The daily loss of Fe by desquamation may be as much as one fourth of the daily urinary iron excretion.

The contents of Ag, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, P, Pb, Se, Sr, Th, Ti and Zn in 143 autopsied liver and kidney specimens from two Ontario communities (Kingston and Ottawa) were determined.

Concentrations of As, Ca, Cd, Cl, Co, Cr, Cu, F, Fe, Hg, I, K, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Se, Sn, V, and Zn were determined in human whole milk samples from Guatemala, Hungary, Nigeria, Philippines, Sweden, and Zaire.

The diseases involved range from multiple sclerosis, various cancers, arthritis, goitre, Down's Syndrome, and mental retardation.
