Book: Metals in Biochemistry

I love bioinorganic chemistry and the role of metal ions in biology. So, whenever I get the chance, I read a textbook, publication or even popular science articles about the metals in biology and medicine. As soon as I saw this book on abebooks.com , I bought it. It's a very short (75 pages) book about the a few metals in biology such s iron, cobalt, molybdenum, zinc etc. The one I have was published in 1980, so lots of things have changed since the publication of the book. But, as the foreword suggests, this book is not a textbook. It is just an introduction about several metal ions that are essential for life as we know it.
