Metal Ions in Biological Systems

The articles published in this volume are based on the papers del ivered at a conference on the Role of Metal Ions in Biological Systems held November 20 and 21, 1972, at Argonne National Laboratory. The purpose of the conference was to present to an interdiscipl inary audience of physical scientists some recent developments illustrating the chemical and environ­ mental participation of the heavy metal ions in the biological system. The invited speakers at the conference are special ists in the
