errors, but none appear to impair the under- standing seriously. The emphasis on the use of Fortran may date the text if Pascal or subsequent generations of structured lan- guages are adopted widely by chemists. The exclusive use of Fortran in the text is not necessarily a flaw, however, since the nu^

merieal methods, once mastered, can be programmed in the newer languages as de- sired. The level af the text is suitable for

Re- searchers who encounter problems requiring numerical methods with which they are not familiar will fmd the text to he a useful refer- ence.

Introduction t o Environmental Studles Jonathan Turk, W. 5. Saunders, Philadel- phia, 1980. vii + 329 pp. Figs, and tables. 19.5 X 26.5 cm.

The author has written an outstanding introductory text for this field, and it should be considered carefully for all serious envi- ronmental studies courses, especially in chemistry. In the author's own words, "in- terrelated problems of ecological disruptions, growth of human populations, land use, en- ergy, nuclear power, food supplies, pesticides, air and water pollution, solid waste, and noise are all eovered."The discussions are readable, current, extensively illustrated, and would be especially interesting to the serious envi- ronmental studies student. The chemical, biological, physical, social, and legal impli- cations of each problem are considered along with attempts a t solution from each of these aspects.

This will be a particularly challenging bmk far the non-seience major attempting that first science course. Nonetheless, it has great flexibility and would he a valuable learning aid for both of the above types of student. There is ample lecture material for a full~year sequence, with ideas for field trips and the laboratory. Selective use of topics would adapt it well to a one-semester course also.

Six general units are organized into fifteen chapters covering specific environmental ~roblems in greater depth. Most chapters include each of the following: an actual case history, a concise summary, a list of key words, take-home experiments with practical everyday applications, problems with a wide

Many environmental science teats are written a t the introductory level and are aimed at freshman who possess little or no knowledge of ehemistry. Although notes on the back cover of this text suggest that this book requires little background in science, the level of presentation is actually fairly sophisticated, and the problem solutions are beyond the capabilities of the average fresh- man. In addition, the use of line structural diagrams for polynuelear aromatics, pesti- cides, and insect pheremones would be meaningless to thaae who had not already had an introduction to organic chemistry. As a result this text would be more suitable for a special topics eourse at the advanced under- graduate level. Each chapter is concluded with an extensive list of references to more specialized books and the state of the art as reported in Science, Chemical and Engi-

ternative energy sources. Those emphasized include coal, nuclear (both fission and fu- sion), and solar. The authors are clearly anti nuclear. The discussion on nuclear power is introduced with. "Since the erim dawn ofthe

also several errors are present. Minor alter- native energy sources briefly noted include wind, ocean thermal gradients, organic wastes, and tides. Thermal pollution is also treated here, although i t would seem more logical to put it in the hydrosphere section.

Part 11, "Atmosphere," is the strongest section of the book. Here the authors discuss the earth's radiation balance, the greenhouse effect, atmospheric layering, the atmospheric chemistry of small molecules including

oxide, nitrogen dioxide, and hydrocarbon automobile emissions. The chemistry of a typical internal combustion engine is pre- sented and contrasted with the chemistry of the Hondaa stratified charge engine. Finally, particulate air pollution is examined.

Part 111, "Hydrosphere," covers acidity due to acid rains and mine effluent, water hard- ness, soaps and detergents, detergent for- mulation and eutrophication, the oceans, sewage treatment (primary, secondary, and tertiary), drinking water treatment, and ag- ricultural pollution.

Part IV, "Biosphere," presents relation- ships between chemicals and living things. Here one finds the nitrogen cycle, the use of fertilizers, the importance of amino acids in nutrition, types of insecticides (their modes of action and persistence in the environ- ment), inadvertent contamination by toxic (industrial) chemicals, tonicity of heavy metals (lead, mercury, and cadmium), and environmental links to cancer.

The two authors have engaged in an am- bitious undertaking. The difficulty of envi- ronmental science lies in its interdisciplinary diversity in contrast to the high degree of specialization normally found in most pro- fessionals. In this case the authors have created a well-organized, interesting, read- able teat.

Its strength lies in its examination of sev- eral ~ * p w I$ ~~i ~ n v i r ~ m n ~ n t ~ t l h w a i q ~ r v in dcplh.

For instance, current toxic waste disposal practices, a growing concern due to problems arising from past practices, are omitted entirely. Figures and tables abound, hut several are never discussed in the main body of the text. While the knowledgeable reader will teadily comprehend, the student will need some help. This problem is parti& offset by the many references. The net result is a stimulating text for a one-quarter or one-semester course, but one which some- times merely whets the reader's appetite for more information.

Students will appreciate the fact that this text is available in an inexpensive ($6.95) paperback edition.

The authors of this book provide the sei- entifie public with a broad overview of the field of enzymology. The topics covered in- clude enzyme isolation, kinetics, classifica- tion, specificity, mechanisms, inhibition and activation, cofactors, structure, biosynthesis, and biology. At the end of the book, an atlas of crystalline enzymes and a table of enzymes is provided. Together these constitute ap-
