The application of the concept of a “controlled environment” led to the identification of eight trace elements with a proven or postulated biol
trace elements is their lack of mutual interaction, which is the basis of Henry’s law of dilute solution. Major elements are the essential constituents of the crystal framework of minerals and rocks; trace elements substitute for or replace major elements. The concentrations of trace elements in...
