ENVIRONMENTAL CHEMODYNAMICS: MOVEMENT OF CHEMICALS IN AIR, WATER AND SOIL (2ND EDITION)

LouisJ. 'rhil~c~lt.aux, John Wiley & Sons. Inc.. Yew York. hY (1996) 593 Pages [ISBN No.: 0-17 1-61295-21 IJ.S. List Price: $69.95

The First Edition of Ihvironmental Cliemdynmiics made an ciutstanding con- tribution to chemical engineers practicing in the Ixirgconing envirc,nniental arena. The First Edition addressed the important features of tlierniodynaiiiics, especially applied to interfacial equilibria, intraphase transport processes (diffusion), and inter- phise exchanges in formiilation and solu- tion o f environmental ergineering prob- lems. However. the participation of chemi- cal engineers evolved rapidly in the d e ~ i d e s of the 1980s and 1990s. The Sec- ond Edition of the hook Fails to reflect the explosion of knowledge in environmental engineering and science, and does not do justice t o thc contributiocs of the chemical engineering profession to this growth.

Chapter One includes a welcome state- ment of go;ils and objeciives. The discus- sion of 1 h i t i and Noniericlature is meticu- lous: it correctly points out the subtle prob- lems of units and quantification. especially as rehted tc) "trace" constituents of environ-

mental media. The entry-level chemical engineer may be more awed than educat- ed; in short, the book serves as a function for formal teaching rather than self-guided instruction. The initial Example and the Problems are important teaching tools but rely too heavily on classic, overly simplistic models of in-stream assimilation and reac- tion processes. Teaching and References values would be enhanced by citation of recent approaches to stream quality analy- sis and regulation, e.g., health-oriented ver- sus technology-oriented options for justifi- cation of industrial discharge limits.

Chapters Two and Three are nicely for- niulated approaches to the application of chemical engineering fundamentals to envi- ronmental problems. The Thermodynamics discussion is clear and concise. The defer- ential citation of Hougen et al. [page 361 is a mark of the author's great respect; it could be improved by additional references to other important works in applied thermodynanlics, e.g., Denbigh, Putzer and Brewer, Sandier, etc. The early incorpora- tion of data on seawater, soils. and rocks is outstanding: most chemical engineers. regardless of academic achievement, have little exposure to geology or soil science. The text creates an awareness of the role played by natural (prototypical) substances. The citation of Brddy is excellent: the early chapters of Brady's book are suited to self- study on the physical and chemical charac- teristics of rocks and soils.

The reference to conditional equilibrium on page 58, relative to Figure 2.1-4, requires emphasis. It is all too often true that paltition coefficients are site specific and cannot be transferred. A brief discussion of weathering, i.e., the kinetics of environmental aging, octanol/water partition relative to natural organic matter, and the extensive recent liter- ature on solution mechanics (especially the work of Rao at the University of Florida) would illustrate this problem. The acronym "ATE"' used on pages 78 and 79 will be mis- understood to mean Adenosine TriPhos- phate by most biochemical engineers. The author does an outstanding job in Section 2.1K; Henry's Law is commonly misused, misunderstood, and misinterpreted by non- chemical engineers. Chapter Three contin- ues the admirable bridge to the environmen- tal from chemical engineering fundamentals; the References and Discussion establish a common ground, Bird et al., Danckwerts, Treybal, Schlicting, Stumm, etc., are time- proven sources of information and ideas.

Chapters Four and Five address aidwater and waterisolid interfaces. Both are instructive but rely too heavily on clas- sic sources. The reader should be warned that this material is intended t o integrate fundamentals with common receiving water management strategies. Practicing engineers engaged in water quality man- agement activities must be aware of State/Federal regulatory attitudes and moni- tor/control methodology research. These chapters are not self-sufficient resources for water quality analysis and design.

Chapter Six is an excellent review of transport in the lower atmosphere and in the vaclose zone in saturated systems. This material is essential and is foreign to most chenlical engineers. As with previous chap- ters, reliance on historic sources of models and data renders the material presented insufficient for transport and remediation analyses; the reader must be aware of this situation. It is wise of the author not to attempt to incorporate recent develop- ments in the text. Practitioners must consult the current literature. Books that attempt to provide guidance for practitioners tend to be short-lived. Material reprinted from Brady is generally good. Figure 6.3-3 is overly simplistic and the statement that the role of "bound" water is not significant is questionable; see page 401. Appendices A through E are well done; readers will find these appendices very useful.

In summary, this book provides a review of chemical engineering fundamen- tals within the context of geologic, atmos- pheric, and soil system processes that are generally unfamiliar to many of the authois students and colleagues. It is outstanding reading, in parallel with current literature, for environmental engineers. It will outlast other recent books that stress legislation, regulation, design, and monitoring prac- tices too heavily. in lieu of fiindnnientals.
