Reports On Astronomy

118,59€ + 10% CARD

 volume XIX A of IAU Transactions contains the reports by Presidents of Commissions, covering the period July 1981 - June 1984. The topics of IAU Commissions deal with all of contemporary astronomy and the present volume therefore constitutes an exhaustive and unique record of astronomical research during this interval. It is particularly useful for astronomers and other scientists who want to gain an overview of a certain field, not necessarily near their own research area. Each Commission President was requested, by early 1984, to begin prep arations for the compilation of his/her Commission report. All members of Commissions were asked to supply details about their individual research pro grammes. The ensuing, very substantial task of concatenating was undertaken in late 1984 by the Presidents, often supported by a team of authors, all recog nized authorities in their fields. In order to preserve some measure of uni formity - which is in any case very difficult with so many authors - editorial guidelines were sent to Presidents, including the number of pages allotted to each Commission.

Primary Productivity In The Sea

118,59€ + 10% CARD

 Primary productivity in the sea accounts for ~30% of the total global annual production. Holistic understanding of the factors determining marine productivity requires detailed knowl edge of algal physiology and of hydrodynamics. Traditionally studies of aquatic primary productivity have heen conducted hy workers in two major schools: experimental laboratory biology, and empirical field ecology. Here an attempt was made .to hring together people from both schools to share information and con cepts; each author was charged with reviewing his field of exoer tise. The scope of the Symposium is broad, which we feel is its strength. We gratefully acknowledge financial support from the Depart ment of Energy, the United States Environmental Protection Agency, the National Oceanic and Atmospheric Administration, including the NMFS Northeast Fisheries Center and the MESA New York Bight Project. Thanks are due to Mrs. Margaret Dienes, with out whose editorial skills this volume could not have been pro duced, and to Mrs. Helen Kondratuk as Symposium Coordinator. Finally, we wish to record our indebtedness to Dr. Alexander Hollaender for his tireless efforts and valuable advice in sup porting all aspects of this Symposium.

Environmental Education - Principles, Methods, And Applications

by Trilochan S. Bakshi e Zev Naveh

59,61€ + 10% CARD

 The environmental movement of the 1960s made educationists in some parts of the world aware of the significance and importance of ecology in curricula at all levels of education, from kindergarten to post-secondary. A great deal of progress was made in the early 1970s in incorporating environmental awareness programs into educa tional systems go that what was once considered a fad was gradually becoming a part of formal education in a number of institutions, especially in Canada and the U.S.A. It was therefore appropriate that an international scientific body devote some time to the issue of ecology in education. Early in 1976, I suggested to the International Association for Ecology (Inteco1) that a symposium on Environmental Education be included in the program of the Second International Congress of Ecology scheduled to be held in Jerusalem in September 1978. In the first draft program of the Congress, the topic was included as a poster session. I considered this inadequate and appealed to the Congress Steering Committee to focus greater attention on environ mental education. The first draft program contained phrases like "utilization of resources", "conservation problems", "environmental moni toring", and "irreversible changes". These phrases more or less assumed that people in general understood ecological principles. Literature on environmental education seems to suggest that a wide gap separated most of the professional ecologists from a large portion of mankind primarily because we the ecologists have paid scant attention to the ecological education of world''s citizens.

Hydrocarbons And Halogenated Hydrocarbons In The Aquatic Environment

59,61€ + 10% CARD

 This volume contains papers selected from those presented at the International Symposium on the Analysis of Hydrocarbons and Halogenated Hydrocarbons in the Aquatic Environment, May 23-25, 1978. The Symposium was organized by the National Water Research Institute of Environment Canada and the Institute for Environmental Studies of the University of Toronto. The purpose of the Symposium and of this volume was to bring together information on the analyses, behaviour and effects of hydro carbons and halogenated hydrocarbons on the aquatic environment. This class of contaminants presents many difficult analytical pro blems, and to a large extent our ability to identify environmental problems and assess their severity, depends on the availability of proved analytical techniques. By exposing workers in this field to the techniques and results of others we hope that progress can be made towards solving the many problems caused by these substances. The papers in this volume are divided into five categories: two plenary session addresses given by J.P. Bruce and O. Hutzinger, 11 papers describing quantitative analytical results, 12 papers on analytical methods, 9 papers on incidence, monitoring and pathways; and finally, 13 papers on drinking water, health and biological effects. We were fortunate in having the support of the many organizations and individuals listed after this preface. In particular we thank B.F. Scott and R. Knechtel for their help in organizing the Symposium, S. Paterson, C. Straka, B. Reuber, A. Bobra, R. Wan, S. Austin, G.E.

Biological Control By Augmentation Of Natural Enemies - Insect And Mite Control With Parasites And Predators

59,61€ + 10% CARD

 The protection of agricultural crops, forest, and man and his domestic animals from annoyance and damage by various kinds of pests remains a chronic problem. As we endeavor to improve pro- duction processes and to develop more effective and acceptable tactics for achieving this protection, we must give high priority to all potentially useful techniques for the control and management of insects. Pest control is recognized as an acceptable and necessary part of modern agriculture. Methods employed vary greatly and tend to reflect compromises involving 3 determining factors: technological capability, economic feasibility, and social acceptability. How- ever, these factors are also subject to change with time since each involves value judgments that are based on available information, cost, benefit considerations, the seriousness of the pest problem, and the political climate. Whatever method is chosen, energy resources continue to dwindle under the impact of increasing popu- lation, and it is inevitable that greater reliance must be placed upon renewable resources in pest management. One alternative is the use of a pest management method that uses the energy of the pest's own biomass to fuel a self-perpetuating control system. The use of biological control agents for the control of pests has long been an integral part of the pest management strategy in crop production and forestry and in the protection of man and animals. The importance and unique advantages of the method are well recognized; numerous treatises deal with accomplishments and methodologies.

Pesticides In Aquatic Environments

59,61€ + 10% CARD

 Water covers about two-thirds of the surface of earth, but only 0.627 percent of this water is the sweet surface and subsurface water available for the survival of freshwater organisms including man (1,2). Some of this fresh or sweet water lies in practically uninhabitable regions (rivers: }1ackenzie in Canada; Amazon in Central America; Ob, Yenesey, and Lenta in Siberia, etc.). Also, most of the major rivers (the Mississippi in U.S.A., the Rhine in Europe, the Volga in U.S.S.R., the Ganges in India, etc.), because they flow through agricultural land or urban and industrial areas, have become highly contaminated with chemicals (3). This leaves us with shrinking resources of sweet surface water. In the United States, the dependable supplies of this water are already dwindling in cities like New York and Los Angeles and states like New Mexico and Texas (3).

Environmental Dynamics Of Pesticides

by V. Freed

59,61€ + 10% CARD

 Pesticides have played a significant role in increasing food production, and in view of growing worldwide food demand we can expect the use of these chemicals to increase. However, some of them have found their way into the biosphere and have been classi- fied as persistent toxic chemicals. This has resulted in serious concern about environmental contamination. Since we are going to continue using chemicals, we should learn more about such aspects as their transport in the environment, the relationship of their physical-chemical properties to transport, their persistence in the biosphere, their partitioning in the biota, and toxicological and epidemiological forecasting based on physical-chemical properties. Environmental chemodynamics is the name given to a subject which deals with some of the above topics, utilizing the principles of such disciplines as chemistry, physics, systems analysis, modelling, engineering, and medical and biological sciences. To ensure the safety of the environment, we must know more about the chemodynamical behavior of pesticides and related chemi- cals. The purpose of the symposium "Environmental Dynamics of Pes- ticides" was to explore the concept of chemodynamics as applied to pesticides and thus may help in developing the emerging field of environmental chemodynamics. The symposium was held during the l37th National American Chemical Society Meeting at Los Angeles, California, during April, 1974. The three sessions in the sym- posium were chai'red by Drs. V.H. Freed, D.G. Crosby, and R. Haque.

Acid Rain Economic Assessment

59,61€ + 10% CARD

 This volume, Proceedings of the Conference ACID RAIN: Economic Assessment, is meant to present the areas of agreement which economists have established and the uncertainties which they have discovered in their attempts to use the methodology of economics to better understand the nature of the acid rain issue. Scientific articles about acid rain initially appeared in 1972. The public turned its attention to the issue in the mid-1970s. In April 1979, the first acid rain bill was introduced in the Senate, authored by New York's Senator Daniel P. Moynihan. The bill sought to establish a federal research program dedicated to filling the gaps in understanding of the phenomena of long-range transport of air pollutants and their environmental, health and economic impacts. 'The bill was passed into law in 1980. Since then, tens of bills have been proposed to control emissions of S02 and NO , x thought to be the precursors of acid rain. And yet, in contrast with the pattern set by the majority of environmental issues, where legislation followed very quickly on the heels of public anxiety and involvement, by July 1985 not a single federal acid rain control bill had been passed.

Short-Term Bioassays In The Analysis Of Complex Environmental Mixtures Iv

59,61€ + 10% CARD

 With this proceedings of the fourth symposium on complex mixtures, we continue to revise and extend our knowledge of genetic methods for the evaluation of chemical mixtures in the environment. The early chapters of this volume are devoted to new bioassay techniques that are directly applicable to the monitoring of environments contaminated with genotoxic chemicals. Microbiological methods have been further refined to meet the special needs of atmospheric monitoring so that very small samples may now be efficiently tested. New in situ methods utilizing green plants actually avoid many of the usual difficulties of sample collection and preparation and offer special advantages in monitoring wastewater, sludges, and hazardous wastes. Insects also are being employed very effectively in the evaluation of gaseous air pollutants in controlled laboratory investigations. Increased emphasis has been placed on a comprehensive assessment of the potential of complex mixtures t9 cause various kinds of genetic damage. New assays for chromosome structural and numerical aberrations in mammalian cells in vitro have been developed and are being applied in laboratory studies. Efforts to link tests for gene mutation and cell transformation in vitro with assays for tumorigenesis in vivo are contributing to the validation of the short-term testing approach. Studies comparing in vitro and in vivo data on a coal conversion by-product, on polycyclic aromatic hydrocarbons, and on mineral fibers are reported in separate papers. Later chapters are devoted to investigations on the fractionation and biological evaluation of specific chemical components within complex mixtures.

Produced Water - Technological/Environmental Issues And Solutions

118,59€ + 10% CARD

 This book represents the proceedings of the first major international meeting dedi- cated to discuss environmental aspects of produced water. The 1992 International Pro- duced Water Symposium was held at the Catamaran Hotel, San Diego, California, USA, on February 4-7, 1992. The objectives of the conference were to provide a forum where scientists, regulators, industry, academia, and the enviromental community could gather to hear and discuss the latest information related to the environmental considerations of produced water discharges. It was also an objective to provide a forum for the peer review and international publication of the symposium papers so that they would have wide availability to all parties interested in produced water environmental issues. Produced water is the largest volume waste stream from oil and gas production activities. Onshore, well over 90% is reinjected to subsurface formations. Offshore, and in the coastal zone, most produced water is discharged to the ocean. Over the past several years there has been increasing concern from regulators and the environmental commu- nity. There has been a quest for more information on the composition, treatment systems and chemicals, discharge characteristics, disposal options, and fate and effects of the produced water. As so often happens, much of this information exists in the forms of reports and internal research papers. This symposium and publication was intended to make this information available, both for open discussion at the conference, and for peer review before publication.
