[Determination of microelements in placenta I. Commun.: spectrophotometric determination of copper content of human placentas (author's transl)].
The copper content of human placenta determined by means of the Bathocuproinemethod lies at 1,21 +/- 0,18 ppm in the fresh and 7,06 +/- 1,04 ppm in the dried material. Furthermore an improved generally applicable method for decomposition of biological materials that prevents the volatilization of trace elements is described.
