title: Lithium and boron in human blood.
abstract: A new method for determination of lithium and boron in biologic material has been developed. It uses neutron irradiation and subsequent measurements of helium 3 and helium 4 in a static mass spectrometer. Concentrations of lithium and boron in blood from seven apparently healthy donors were in rather narrow ranges (Li = 2.64 +/- 0.94 ng/gm dry weight, B = 97 +/- 22 ng/gm dry weight), and these concentrations also appeared to be correlated at the 0.05 level of significance.
