191 in the other industrialized countries, which have different laws, other rules, dissimilar labelling, diverging concepts regarding some of the risks, safeguards and controls. Finally, in the case of a few (not all!) of these sections, 95% of the general bibliography is pre-1960. It is hard to believe, that in an era of general technical upheaval, so little had to be added to some fields.

Air Pollution Reference Measurement Methods and Systems, edited by T. Schneider, H.W. de Konig and L.J. Brasser (Studies in Environmental Science Vol. 2), Elsevier, Amsterdam, 1978, 168 pp. Price: US$35.50: Dfl. 80.00. In the last few years, there has been a growing recognition of air pollution as a global problem. The International Workshop on Air Pollution Reference Measurement Methods and Systems (Bilthoven, The Netherlands, December 12--16, 1977) was convened with the assistance of the World Health Organization as co-sponsor, not only to review the current state-of-the-art in the field, but also to prepare a plan for further development of an International Air Pollution Reference Measurement System. Very few papers dealing with measurement methods, which strictly speaking are not reference methods, have also been included. This book reports the results of the workshop. There is an urgent need for the application of reference measurement methods in international programs. This work discusses a number of applications in the field of air pollution, with emphasis on mobile and stationary calibration systems. Reference measurement methods which are presently available are described. An outline is given of quality control procedures and techniques in data handling and data presentation. Finally, recommendations and follow-up projects are presented, including international projects that will contain and apply the reference principles discussed during the workshop. The book will serve as an up-to-date review of the status of air pollution reference methods and systems for technicians involved in air pollution and will also provide useful background information for those involved in air pollution activities in general. It is hoped that this work will stimulate greater international cooperation in the development of good reference systems.

Air Pollution Control Technology, by Robert M. Bethea, Van Nostrand Reinhold, Wokingham, 1979, 449 pp. Price: £22.30. Air pollution c o n t r o l seems a really crowded topic! This is the third book with approximately t h e same coverage reaching the reviewer within a few months. Although t h e r e may be more in the last year's crop, I consider the

192 sample representative. In the Preface, Professor Bethea states t h a t the book is the transcript of lecture tapes, therefore its direct style and its short sentences. Instead of the usual highbrow impersonal, he addresses t o reader as " y o u " . But sometimes, live lecture transcripts give an unusual, staccato style. For example: "Oxidation reactions are usually heterogeneous. Unfortunately, all heterogeneous catalysts deteriorate with use. Platinum is the m o s t widely used catalyst. Palladium is also common. The metal surface must be large to provide sufficient active sites on which the reactions o c c u r . . . " A bit like shorthand. This style is necessary to cover within one slim volume so m a n y subjects as: problem definition, engineering studies, evaluation of control devices, economic aspects, control system selection and implementation for particulate, gas and vapor control technology. The treatment is fully adequate for the undergraduate and graduate readership. It will even be useful in some instances to the plant engineer seeking quick reference either on venerable old methods outside his narrow field, or some basic information on advanced technologies as ionizing wet scrubbers, hot-side electrostatic precipitators, or techniques in adjusting particle resistivity for electrostatic precipitators, and so on. As I already mentioned at the beginning of this article, this is one of three books I reviewed recently. If the reader who cannot afford to b u y (or incite his librarian to order) three books on air pollution control would ask m y choice, I would not hesitate to recommend Industrial Air Pollution Handbook, edited by A. Parker (see m y review Sci. Total Environ., 11 (1979) 293--294). The second best would be Professor Bethea's volume discussed here. Only a very far runner-up would be Air Pollution Control and Design Handbook, edited by P. N. Cheremisinoff and R . A . Young, which I have also reviewed (Water, Air, Soil Pollut., 10 (1978} 499--500).

Sulfur in the Environment, Part 1: The Atmospheric Cycle, 464 pp., $32.40; Part 2: Ecological Impacts, 482 pp, $32.00. Edited by J. O. Nriagu. WileyInterscience Series of Texts and Monographs, New York, 1978. On the flap, this text is called " a comprehensive interdisciplinary volume of articles". To begin with, congratulations to the person who found this befitting four-word definition. I hesitated among such terms as "contesseration of monographs"; "limited scope encyclopaedia" (i.e. limited to the subject matter as announced in the title); "coace~'ation of topical papers" and so on, but neither is as good as the one on the flap, though each contains an element of truth. The coverage is indeed encyclopaedic. The primary focus has clearly been on the process of change and the ecological stresses stemming from environmental sulfur pollution. Part 1 includes papers on the sources (Chapters 1--3), behaviour (Chapters 8 and 9), and transport (Chapters 5--7) of sulfur • in the atmosphere. Chapter 4 on the costs and benefits of sulfur emission
