Chapter 9 is truly abbreviated, con sidering the ubiquity of lead pollu tion. It fails to describe t h e use of stable Pb isotope analysis (e.g., the e l e g a n t w o r k p e r f o r m e d by C l a i r P a t t e r s o n ) , which h a s g r e a t l y e n hanced our understanding of the glo bal environmental chemistry of this metal. In contrast, Chapters 10 (Hg) and 11 (As) are exhaustive in their p r e s e n t a t i o n s of cycling a n d i n t e r conversion of metal species; Chapter 11 strongly e m p h a s i z e s speciation analysis and exhibits the most cos mopolitan reference list. Chapter 12 (Tl) focuses on modern techniques and references only older methods or those less applicable to analysis a t e n v i r o n m e n t a l concen trations. Chapter 13 places the ana lytical chemistry of Cr in a broad en vironmental context and provides a vast range of references. Some repe tition of instrumental techniques ap p e a r s in C h a p t e r 14 (Co, Ni) a n d could easily have been omitted, but the section on electrochemical meth ods is outstanding. Chapters 14 and 15 (Al) m a k e excellent use of tables to present background information and recommended procedures.
Chapter 16 reads like the Analyti cal Chemistry biennial reviews, which may be appropriate considering the broad range of environmental con centrations of Se. Much of Chapter 17, which covers quality a s s u r a n c e a n d v a l i d a t i o n of r e s u l t s , reflects common sense, b u t t h e s e practices are essential for performing reliable analyses and for comparing results from different laboratories or tech niques. The organization and scope of the metals chapters are good, although a European slant to the book surfaces in t h e r e f e r e n c e s cited. However, given t h e large a m o u n t of environ m e n t a l work performed in Europe, this is not surprising. The reference lists for the c h a p t e r s are generally comprehensive through the late 1980s. Overall, many aspects of environ mental analytical chemistry are well described, and the reader is provided w i t h a b r o a d r a n g e of r e f e r e n c e s . This book will be a useful addition to t h e reference l i b r a r i e s of e n v i r o n m e n t a l scientists but may not be of widespread use as a graduate text in environmental analytical chemistry.

Complexation Chromatography. D. Cagniant, Ed. vii + 294 pp. Marcel D e k k e r , 270 M a d i s o n Ave., N e w York, NY 10016. 1992. $100 Reviewed by Jerome W. O'Laughlin, De partment of Chemistry, University of Mis souri, Columbia, MO 65211 In the preface to this text, the editor introduces three fundamental types of molecular interactions t h a t give rise to charge-transfer absorption or electron donor-acceptor (EDA) chro matography, argentation chromatog raphy, and ligand-exchange chroma t o g r a p h y (LEC). The t e x t r e v i e w s these t h r e e types of interactions in chromatography u n d e r the general heading of complexation chromatog raphy. Many of the applications discussed in this volume are taken from the lit e r a t u r e of the 1960s and 1970s, be fore capillary columns were as widely used as they are today and prior to t h e d e v e l o p m e n t of t h e efficient H P L C c o l u m n s now a v a i l a b l e . It might be questioned w h e t h e r many of the applications presented in the text would even be considered today.
