Our Association's 1972 International Clean Air Conference was held here in Melbourne last month and in retrospect it is necessary to analyze whether it was successful from the point of view of the Association's aims. The source of a growing number of them was the Atmospheric Physics division of C.S.I.R.O., showing an interest in air pollution. A third feature of the conference was the trade show which was held in conjunction with the conference.
However, the most important thing from the Company's point of view has been the increasing recognition of the necessity to work for Clean Air and the important contribution that the Company has made to this. The third international clean air congress of the International Union of Air Pollution Prevention Association will be held in Düsseldorf in August. Furthermore, a state reception was held for the conference organizers and some of the overseas guests, where the Acting Prime Minister, Mr. Hamer, the Ministers for State Development, Health.
1972 INTERNATIONAL CLEAN AIR CONFERENCE MELBOURNE, 15th-18th MAY
All papers, except for some of these keynote addresses, were available at the beginning of the conference in the published papers. However, tall stacks are not sufficient for particulate matter and removal efficiencies in the order of 99% are needed. Unfortunately, the diversity of sources in cities is not amenable to this due to the large areas of modern cities.
Long-range effects of air pollution are also a problem, as sulfur dioxide can be carried over distances of the order of 100 to 1000 km. O'Brien was appointed early last year as Director of the Department of Environmental Protection. Michael Treshow, of the University of Utah, discussed the effects that air pollutants have had in the United States; sulfur dioxide from copper ore smelting, fluorides from aluminum production and ozone, PAN and NO.

In fact, the process that appears most promising is fuel oil gasification followed by removal of sulfur as hydrogen sulfide prior to combustion. Cortelyo it's decision time; advocates of the Western Australian Environmental Protection Authority and Council Minister for Environmental Protection, Mr. The administration will have a major responsibility in improving the quality of the environment and in controlling and, where possible, preventing any pollution to the environment.
Commissioner of Public Health (Dr. W. D. Davidson); Chief Engineer, Metropolitan Water Supply Board (Mr. R. Hillman); Commissioner of Town Planning (Mr. J. E. Lloyd); Surveyor-General (Mr. J. F. Morgan), and the Deputy Conservator of Forests (Mr. W. D. R. Stewart). Treshow, when the internal combustion engine is conquered or replaced, the vegetation of the world's ecosystems, crops and man will be completely destroyed. Environmental Protection Agency, which were respectively titled "New Systems for Air Pollution Control" and "The Old, the New and the Future in Air Pollution Instruments", were not available to the author at the time of writing this brief summary.
FEDERAL AIR QUALITY DATA
COLLECTION IN THE UNITED STATES
R. Mongan
These were mainly the uneven quality of the data collected and the surprising variety of forms (and formats) in which it appeared. The main flaws in the conceptual design of the NADIS system appear to have been as follows. A better approach, especially in light of the imprecise specification of data needs, would have involved collection.
The first step is to determine the uses that will be made of the collected data. The choice of mode of operation of the scanning electron microscope can limit, to some extent, the type of sample collection method that can be used.

In my opinion the above balance sheet and statement of operations of the Clean Air Society of Australia and New Zealand have been properly prepared to give a true and fair view of the state of affairs of the Society as at 31 December 1971 and of its income and expenditure for the year ending December 31, 1971. Part of the conference program will deal with the hazards and problems of asbestos and silica dust, dust concentrations in granite and other quarries, metalliferous and coal mines, and in mines dealing in radioactive materials . Other sessions focus on dust particles in iron and steel factories. Filters in foundries and aluminum smelters, filter tests and the development of instruments for concentration measurements also form the basis of the articles.
4 4th ANZAAS Congress Sydney, August The next ANZAAS Congress will be held at the University of New South Wales and the Congress Circular lists a number of sessions which will be of great interest to members of the Society and readers of Clean Air. Butler, Dean of Science, University of Sydney, and will discuss the biological and physical limitations on the carrying capacity of the global environment (Prof. L. C. Birch and Prof. R. M. May), World population growth (Prof. J. C. Caldwell) and population control (Prof .C.W.Emmens). Maiden, Vice-Chancellor of the University of Auckland and a Car Emissions Control Authority.
BOOK REVIEWS
- STRAUSS
- E. DRIVER Electrochemistry of Clean Air
- STRAUSS Air Pollution Control
- S. BASDEN
Bagg of the University of Melbourne, is a comprehensive review of 54 pages and a bibliography with 195 references. The subjects of the review cover the entire field of nitrogen oxides; namely: (i) formation kinetics; (ii) emissions from cars, diesel engines, combustion devices (on solid, liquid and gaseous fuels) and chemical plants; (iii) biological effects; (iv) the role of nitrogen oxides in photochemical reactions; (v) measurement;. Temple, of Aston University in Birmingham, is the fourth review; and to a certain extent complements it.
Furthermore, 34 of the 36 figures in the text are taken from copyrighted material held by major car and parts manufacturers, also indicating that they are relatively inaccessible in their original form. Nevertheless, the article is an excellent overview of the subject at the level of its development in late 1968. Also included in the overview are methods for measuring particle-fiber adhesion forces and a review of the relevant University of Melbourne (although the former author is now at Westinghouse R. and D. Center, Pittsburgh, Pa.) – includes 48 pages and 60 references.
1972 CLEAN AIR CONFERENCE PROCEEDINGS
This overview is particularly valuable because the majority of the references come from various Automotive Engineering Congresses of the Society of Automotive Engineers, and are accordingly relatively inaccessible. In a footnote in the article, the author points out that during the preparation of the article, most major car manufacturers made rapid progress in the development of control systems, and therefore much material could not be included without delaying publication. The author covers the subject in a very thorough manner, from Gilbert's observations in 1600 through to the relevant developments in the literature of 1968.
The topics covered can be summarized as follows: (i) fundamentals and historical origins; (ii) mechanisms of corona formation and current-voltage-field relationships; (iii) particle loading; (iv) particle collection and calculations of collection efficiency;. v) the aerodynamics of gas and particle flow through precipitators;. vi) precipitation under extreme conditions of temperature, pressure and particle resistance; (vii) various applications such as pilot plant and model studies, financial aspects, operation and maintenance, explosion hazards and industrial standards. The article is an excellent overview of the theoretical aspects of filtration, and deals with the mechanisms of particle separation from the entraining medium and adhesion to the fibers of the experimental results related to the same topic. Four of the papers have a Table of Notation appended to them, which is of great help to the casual reader; but one of these (attached to Review No. 6) gives no units or dimensions to the various symbols, which may be a slight handicap to a reader new to the field in question.
The third review, by Werner Strauss of the University of Melbourne, entitled "Control of Sulfur Emissions from Combustion Processes", comprises 79 pages and a bibliography of 114 references. As the authors point out, in the post-war years a considerable amount of work has been done in this area, but recently the literature on cleaning phenomena has declined significantly. The review deals with the topic of aerosol particles that are created by the condensation of vapors on them, and the effectiveness this has on cleaning performance by various mechanisms.
The review concludes with an excellent discussion of actual condensate scrubbers with numerical examples of calculations of various performance parameters. In any case, the reviews are excellent and should fulfill the goals stated in the preface, namely to provide a suitable background for engineers and scientists faced with particular air pollution control problems and for researchers in the field of control improvement. Although somewhat expensive at $20.95, the volume can be considered an essential text for postgraduate students in environmental and pollution control courses (especially those coming from an engineering or science-based background), and can be recommended as a reference book for students of in science or engineering who expect to work in pollution control after graduation.
