The increasing production of industrial goods, heat, and energy, as well as traffic, has led to the release of considerable amounts of toxic trace metals to the atmosphere. The result is elevated concentrations of toxic metals in local populations and eco systems. Recently the problem of atmospheric long-range transport of trace metals has also been recognized. Significant amounts of these pollutants are disposed and deposited both on regional and global scales. In the atmosphere they may influence the chemical reactions. Of particular interest is their catalytic effect on the oxidation prosesses taking place in water droplets or on the surface of wet particles (e. g. the oxidation of sulphur dioxide to sulphate), however, the main environmental impact starts when the atmospheric trace metals are deposited on ground and vegetation and subsequently brought into the water circulation. During the later years significant progress has been made in the development of equipment to reduce and control the atmospheric emissions of toxic trace metals. This particularly applies to electrostatic precipitators and wet scrubbers for the collection of fine particles. The main objective of the workshop was to survey present knowledge concerning the sources, atmospheric fluxes, sinks and chemical impact of the atmospheric trace metals, and to review the developments of emission control equipment and the perspectives to reduce the potential risks from toxic metals. During the first two days of the meeting, 15 invited review papers were presented.

Under current U.S. EPA guidelines, particularly the Clean Air Act Amendments, stack gasses and the solid products of combustion require specialized treatment for removal of trace metals. This book presents a data-intensive assessment of the fate of trace metals during combustion. The data are derived from actual operating combustion systems, and the text emphasizes case studies that document trace metal fate control. Issues covered include metal volatility, metal reactions, and trace metal management through the enhancement or inhibition of specific chemical reactions.

This volume discusses major areas of primary concern for the understanding of the complexity associated with ecological trace element research. These include sources and fates of trace elements; analytical techniques; and the distribution of trace elements in biota and soil and sediment reservoirs. Case studies, field work and laboratory studies intensively discussed in this volume are useful to enhance our knowledge about processes related to the biological response of trace metal stress under realistic environmental conditions.

In 1949, when the North Atlantic Treaty was ratified, one of its articles explicitly noted '1hat member countries should contribute towards the further development of peaceful and friendly international relations." Specific problems related to the human environment were addressed by the Committee of Challenges of Modern Society (CCMS) of NATO, established in 1969. This provided a framework within which a series of International Technical Meetings (ITMs) on Air Pollution Modelling has been held. This volume documents the proceedings of the 18th meeting in this series. Science, like the arts and sports, provides an ideal vehicle for "developing peaceful and friendly international relations". National boundaries have never been barriers to the movement of air pollution, and fortunately this has also proved true of scientists studying the transport of air pollution. It is thus satisfying to record that since the mid-seventies it has been commonplace to find Eastern European scientists among attendees at the ITMs which have (in a very modest way) participated in a precursor to the process which has led to historical changes in Europe and which will undoubtedly lead to a tremendous increase in personal and intellectual exchange on a worldwide basis.

Air pollution has historically been viewed as a local or regional scale problem with attention focused on acute episodes such as the sulphur dioxide and smoke smogs of London in the 1950s and 1960s and the photochemical smogs of southern California first recognized by Haagen Smit in the early 1950s. In recent years, however, it has become apparent that human activity has, and still is, changing the chemical composition of the atmosphere on a global scale. The composition of the atmosphere has seen enormous changes due to natural processes since the formation of the planet. Data obtained from air bubbles trapped in polar ice are beginning to reveal information about these changes over the last tens of thousands of years and geochemical models of the evolution of the Earth give us insights into the changes over much longer periods of time. Perhaps the crucial differences between these natural changes and those now being induced by man are their rel ative rates of change. The magnitude of present day fluxes of some com pounds released as air pollutants is in some cases much larger than those arising naturally. In other cases, for example carbon dioxide, the an thropogenic emission rates are small compared with that of the natural cycle, but the kinetics of the system are such that the steady state concent rations of the compounds in the atmosphere are now being perturbed.

In the early 1980s, forest decline became a matter of public and scientific concern when forest stands with Norway spruce (Picea abies [L. ] Karst. ) showed evident damage on a large geographical scale throughout Europe. The causes of the observed symptoms could not be elucidated on the basis of the state of knowledge at that time. Therefore, several research projects were launched both in Germany and in some other countries in order to identify the relevant pathogenic factors. In 1985, the Federal Ministry for Research and Technology decided to include the site "Postturm", forest district Farchau/Ratzeburg, in the spon sorship of the research on forest decline as a site typical for lowlands and a sphere of anthropogenic urban influence. The investigation area is situated about 40 krn east-northeast of the city of Hamburg. Since spruce trees in particular showed severe decline, emphasis was laid on this species. The programme started in 1986 and extended to 1992, with some activities con tinuing beyond this time. Working groups from 13 institutions took part in the overall project.
