Title: Book1 Author: Joy Created Date: 1979-03-01 Message: I found several webpages, all of which cited the same list, reprotedly from the now-defunct U.S. Bureau of Chemistry and Soils. The original list shows elemental composition of the human body by weight, not including the trace elements: manganese, zinc, copper, aluminum, cobalt, selenium, chromium, etc.Using hydrogen as a standart, I converted this table into elemental composition by We identified major differences in elemental concentrations between sperm and seminal plasma and that higher sperm copper, sulfur and calcium are quantitatively associated with poorer semen quality and increased frequencies of genomic sperm defects.

Article Text; Article info; Citation Tools; Share; Responses The elemental composition of the human body can be looked at from the point of view of either mass composition, or atomic composition. To illustrate both vie A review is presented of the elemental composition of human and animal milk with special reference to trace elements. Literature data are discussed and tabulated in 50 separate tables (one for each element) mainly for the period after 1950. Each table uses a standard format comprising 10 columns indicating (1) source of milk.
