BOOKS The first section discusses challenges i n h e r e n t i n e n v i r o n m e n t a l analyses, including appropriate sampling and sample storage (e.g., Chapter 2) as well as long-term specimen banking (Chapter 3). Chapter 4 describes wine as an example of specimen banking and is mostly of historical interest. Chapter 5 is of major importance because it a l e r t s t h e r e a d e r to t h e common pitfalls of sample treatment. It comprehensively covers identification and avoidance of systematic err rors as well as ways to minimize (or eliminate) sample loss and contamination during sample processing, using detailed examples for a variety of sample types. A rather general but thorough survey of currently available analytical and i n s t r u m e n t a l m e t h o d s is provided in Chapter 6. Chapter 7, which emphasizes the use of wet chemistry to evaluate the environmental mobility of metals, is particularly interesti n g . A l t h o u g h some s e c t i o n s a r e rather elementary, providing only a cursory look at metal speciation and transformations in t h e environment, the chapter is replete with specific

broadly, although a discussion of tin is noticeably absent. Because of the diverse professional backgrounds of t h e chapter authors, t h e r e a d e r will find t h e t e c h n i c a l content somewhat inconsistent. Some a u t h o r s do a splendid j o b of describing the relevant environmental c h e m i s t r y of each m e t a l in t h e context of its analytical chemistry. A few focus purely on t h e analytical aspects, and others present material in a manner similar to that of the biennial reviews in Analytical Chemistry. The organization of the book leads to a certain amount of repetition in t h e description of a n a l y t i c a l techniques. Certain a u t h o r s discuss t h e specifics of instrumental techniques in too much detail. The editor might have eliminated some of t h e r e d u n dancy by encouraging authors to refe r e n c e o t h e r t e x t s or t o r e f e r to Chapter 6. Chapter 8 (Cd) is a good compilation of methods in a variety of matrices. I t is t h o r o u g h , provides good background information, and includes a helpful section on speciation. However, very little environm e n t a l geochemistry is p r e s e n t e d .
