"Active" speciation

Element Speciation in Bioinorganic Chemistry S. Caroli, Ed. John Wiley & Sons 605 Third Ave. New York, NY 10158 1996, 474 pp.. $95

other chapters cover chromium and selenium, arsenic, milk, and aluminum and silicon; and technique-based chapters focus on neutron activation, "new methods", nonchromatographic methods, and quality control. Why is chromium discussed with selenium in one chapter? Well, the methods applied to these two elements are not particularly successful for either, so there is some relationship—but that is a cynic's view. On the whole, the book is well-written and thoroughly referenced. The blurb on the back of the book stating that it is "a

The book contains an excellent chapter on electrochemical methods.

Knowing more about sensors

Handbook of Chemical and Biological Sensors Richard F. Taylor and Jerome S. Schultz, Eds. Institute of Physics Publishing 150 South Independence Mall West Suite 1035 Philadelphia, PA 19106 1996, 603 pp., $279

The word "speciation" can be used in an active sense (i.e., the work of an analytical chemist who is speciating a sample) or a passive one (i.e., the chemical species in which an element occurs). This book deals mostly with the active sense: It is Interest in developing miniature chemical about methods.

physical sensors but is useful for understanding chemical sensor transduction discussed in later chapters. Some transduction methods are not covered in the early chapters but are described in the second section of the book, which primarily deals with examples and applications. Thus, readers who do not read this book cover to cover or who do not closely read the table of contents may not gain a good overview of the entire field. All of the significant transduction techniques are covered, including optical, electrochemical, piezoelectric mass detection, and calorimetric methods. In all cases, the authors do a good job of covering the basic theory of the transduction mechanisms. References are provided for those wanting to obtain more detailed information. The later chapters in the first section of the book describe chemical and biological methods of analyte recognition and how it can be linked to transduction. The supporting topics of microfluidics and sensor calibration are also included. The calibration chapter is particularly informative because of its discussion of zero-, first-, and secondorder sensor systems. The analyterecognition descriptions provide a comprehensive overview but do not include in-depth coverage of any particular area. Again, ,eferences point the reader to greater detail. The final chapters describe current and potential applications for chemical and biochemical sensors, and numerous examples illustrate the various combinations of sensor recognition and transduction. Some material that appears in earlier chapters is repeated, but this redundancy highlights important areas and does not detract from the work. One chapter discusses potential markets for commercial sensors—a topic not often covered in scientific books. If it is safe to assume that many readers of this book will be working for commercial interests then the discussion of markets sppms

This book presents material from the December 1995 symposium "Environmental Biomonitoring and Specimen Banking" held at Pacifichem. It contains an overview chapter, eight chapters on monitoring, six chapters on exposure assessment, four chapters on biomarkers, and five chapters on specimen banking. Most of the references are from the 1990s. Author, affiliation, and subject indexes are included.
