“…A book dealing with the analysis of foods has been published: the most recent text in the Food Bioactive Ingredient series, “Analytical Methods in the Determination of Bioactive Compounds and Elements in Food”, contains a substantial chapter on elemental speciation 15 and a chapter devoted to the “Two Sides of Selenium: Occurrence and Determination of Selenium Forms in Food and Environmental Samples Using Analytical Methods”. 16 Two texts devoted to toxicology have appeared, one of which is devoted to the toxicology of metals. The fifth edition of the two-volume “Handbook on the Toxicology of Metals” contains a well-written introductory chapter in the first volume (General Considerations 17 ) and a second that discusses the relevant chemistry of metals, sampling, analytical methods, and speciation.…”
