each symbol in the diagram means are not given. These details are not needed by the practicing process engineer, but for those of us who are not in the area need some explanation is needed. Although chemical precipitation is discussed, the details of metal ion precipitation are not stated. This is one topic that needs significant explanation as heavy metals are probably the most common of all industrial wastewater contaminants. Again, on a positive note, the author’s Žpresumed. chemical engineering background shows when he discusses reaction time and mixing Žhorsepower. requirements. Missing was any treatment of oil removal Ža topic of particular interest to this reviewer.. This omission was surprising as industrial wastewaters are contaminated with oil about as often as they are with heavy metals. I looked for oil removal in the chapter of flotation — but it was missing. The author dealt solely with solids removal. Moreover, he only discussed DAF Ždissolved air flotation., ignoring IAF Žinduced air flotation. and NAF Žnozzle air flotation. systems. He provided a number of references Ž13 in all. but none more recent than 1992. The second volume in the series, Biological Processes, dealt with the different biological processes in separate chapters on activated sludge systems, lagoons, fixed-film processes, aerobic digestion and anaerobic waste treatmentranaerobic sludge digestion. The book ends with a chapter on sedimentation. The final book on the series is entitled Specialized Treatment Systems. It could really have been Žfor the most part. entitled‘‘Advanced Wastewater Treatment Technology’’ containing, as it does, chapters on adsorption, ion exchange, stripping, filtration and membrane technology. Other Žnon-conforming to the title. chapters deal with dewatering and hazardous industrial waste incineration. The last topic seems to be the‘‘odd-man-out’’ in a book dealing with wastewater. More conventionally, the author could have discussed Žsewage. sludge incineration among other topics of sludge disposal. While sludge disposal is not thoroughly covered, sludge dewatering is in the last chapter of this volume. In conclusion, despite the minor criticisms above, I can only complement Celenza on his writing this excellent series of books. Time and again I was impressed by his knowledge of the field and practical suggestions. The detailed numerous examples he calls Case Studies, numbering 33 in the three texts, adds immeasurably to the book’s utility. Adding a few student problems at the end of each chapter would make these books attractive as texts for a university course. GARY F. BENNETT PII: S0304-3894Ž00.00262-4

material in an encyclopedia-type format, i.e., an overview of the field. In comparison to the other volume dealing with water pollution, this book appears to be more up-to-date in its treatment of the topic Žbased on a review of the dates of the referenced articles.. Air Pollution addresses the sources and results of air pollution and how pollutants influence the environment. It surveys all aspects of management, including dispersion modeling, emission measurements, air quality and continuous emission monitoring, remote sensing, and stack sampling. In addition, the book explores methods of reduction and control, with particular attention to gaseous emission controls and odor control. This volume has six chapters titled as follows: Ø Ø Ø Ø Ø Ø

Pollutants: Sources, Effects, and Dispersion Modeling; Air Quality; Pollutants: Minimization and Control; Fugitive Emission: Sources and Controls; Odor Control; and Indoor Air Pollution.

Written by a series of 13 contributors, the coverage of air pollution seems quite complete, beginning with sources of air pollution and ending with a discussion of indoor air quality. Even radon, its source, impact and control are covered. Another current topic was biofiltration control of air pollutant emissions. But like its companion volume Žon water., the material is dated. I could find no discussion of PM 10 and PM 2.5 Žsmall particles. nor of emission trading; both are recent Žbut not too recent. air pollution problemsrsolutions. The theory underlying air pollution Ždispersion modelling. and its control Ždevices. is discussed. Appropriate equations are presented, but only rarely is their use illustrated Ži.e., mathematical examples given.. My overall analysis of the book is that it is well written and complete Žin its topic coverage., but lacking in depth and not as up-to-date as I would like. GARY F.

Measuring and modelling investigation of environmental processes R. San Jose ŽEd..; ISBN 1-85312-5660, WIT Press, 1999, 361 pages, price £110 This book grew from the proceedings of the First International Conference on Measurements and Modelling in Environmental Pollution, held in Madrid in 1997, when selected authors were given the opportunity to prepare extended papers of greater depth and detail. The result is a set of 12 papers of about 30 pages each, arranged fairly
