Trace elements found in the human body are iron, manganese, zinc, copper, iodine, cobalt, molybdenum, selenium, chromium, silicon, fluorine, vanadium, nickel, arsenic, and tin. See also elements, biological abundance.
Because living things serve to locally concentrate trace elements, accumulations of these elements in rocks serve as biomarkers which astrobiologists will be able to use in their search for extraterrestrial life.
