inorganic molecules and polyatomie ions are never discussed in spite of the promise stated a t the bottom of page 49. Electronegativitvisineorrectlvdefined o n 0 72. Thedefinition given is for electron affinity. Electronegativity is a measure of the ability of an atom in a molecule to attract bonding electrons to itself. On p 83, the authors state that hydrogen must (book authors' italics) he attached to F, 0 , or N in order for hydrogen bonding t o occur. This statement may seem overly dogmatic t o those chemists who investigate weak hydrogen-bonding interactions involving hydrogen with other electronegative elements. In Chapter 5, the brief description of the Kinetic Molecular Theory neglects to mention that its postulates are for an ideal gas. The concept of an ideal gas or the ideal gas law is never discussed. A few minor points further illustrate problems that are encountered throughout the book. On p 145, the statement is made that "dissolved nitrogen is physiologically inert; it does not do any harm while dissolved in the blood."

T h e use of these units is no longer appropriate. Overall the authors have done a reasanable job of presenting these three areas of chemistry in a compact space. However, rigor has been sacrificed, and because of this lack of rigor this reviewer cannot recommend this teat for those students in the health and life sciences curricula.

The author claims to present 15 to 20 weeks of classical quantitative analysis, plus an introduction to instrumental methods, suitable for a wide variety of students. Unfortunately, he tried to address too many audiences. A five-page introduction t o oreanic is inconsistent with the inclusion of chromatography chapter. Chapters start with learning goals and end with a programmed summary, questions, and problems, all of which seem to be tailored to the needs of the nonmajor.

of halides. Another extracts iron (111) into ethyl acetate then hack into water, with neither separation from another metal nor a recommended measurement. The last is a determination of "total salt" using ion exchange and neutralization. The only instruments employed are the balance and pH meter! The ever popular Spectronic 20 rated barely a page of text and no experiment. Analytical chemists will object to use of a buret to dilute a sample before titration (p 117), numerous drawings of digital pH meters displaying unrealistic values (pp 290, 291, 292, 296, e t al.), titration of 200 mL of anslyte with 100 mL of titrant f p 341) and failure t o mention Class A volumetric ware. Neutralization theory is spotty and the impo~tanceof buffers and equivalence point pH is not convincing; only a t the end of C h a ~ t e 5r does it become apparent that DI! DOH = 14. Bv contrast.-Che influence of cumplexing un solub:lity and cslrulnrion of e q u i u l e m t p i n t potential were well done. H w t v r r , the nurhur overlooked sewrnl opportunities to emphasize competitive equilibria, particularly in precipitation methods, indicator action and masking in EDTA titrations. Oxidation-Reduction Equilibria is easily the worst of the classical chaoters. The summaticm uf hulf-reactimi l i discusred but tvalancing of hnlf-react~unuby thp ion-electrcm methud is ignorcd. Stoichiometry is nor mentioned as a primary reason for using the change of oxidation state method. Introduction of the Nernst equation (p 294) intermixes real and hypothetical examples. The early chapters contain many cross references, unnecessarily long examples (often without units), and too much redundancy. Chapter 12, on Oxidation-Reduction Titrations, is the only one to discuss reagents and applications. Twice t h e equivalent weight of a primary standard is calculated (pp 344, 352) without mention of its utility or the importance of its magnitude. T h e introductory chapters (analysis, techniques, treatment of data) are traditional; the nonaqueous solvents chapter could have been omitted so that precipitation titrations and precipitation from homogeneous solution might be presented more adequately. This hook includes most of the topics found in modern instrumental texts, but many received such a superficial treatment that they should have been omitted altogether. Often a topic appears in two chapters (emission spectroscopy, pp 559, 597; fluorescence, pp 549, 568, 584; and ion exchange, pp 463,508). Such fragmentation is confusing and repetitious. Few references are cited and most instrument manufacturers are not credited (e.g., Fisher, p 123; PAR, p 402; Waters, pp. 516, 520). These chapters contain very few prablems and examples. The uninitiated reader will have difficulty puttingthe instrumental chapters into perspective. This text is adequate for a nonmajors course,hut most instrumental chapters will go unused. Majors will need greater coverage than these 267 pages offer and should have broader quantitative analysis experience than afforded by the other portions of this text. Frank A. Guthrie

Chemists and biologists must often work with potent carcinogens, either because they are studying carcinogenicity or because the carcinogens are uniquely suited for other purposes. Sooner or later they must deal with the troublesome problems of cleaning up spills and disposing of contaminated waste or unused carcinogens. This manual provides them with practical guidance for the tasks. Physical, chemical, and physiological data are given for 76 carcinogens and classes of carcinogens (e.g., aflatoxins, nitrosamines). There are directions for dealing with soills of each carcinoeen and for detoxifvinn and disnosine of it or of waste contam.,~.. inated with it. Theauthors have tested most of the disposal methods for completeness of reaction. Others have been tested in studies sponsored by the International Agency for Research on Cancer, in which some of the authors participated. Blaine C. McKusick ~~~~~~
