In October 1979 the First European Symposium on Physico-Chemical Behaviour of Atmospheric Pollutants was held In Ispra (Italy); 83 scientists attended the conference contributing 44 papers. Ten years later, the Fifth European Symposium on Physico-Chemical Behaviour of Atmospheric Pollutants, organized as for the previous Symposia In the framework of the Concerted Action *COST 611, was held in Varese (Italy) from 25 to 28 September 1989. This Volume contains the oral papers and the posters presented at this Symposium. Participation at this Conference Is more than doubled of that In 1979 In terms of scientists (185) and contributed papers (110). This simple comparison demonstrates once more the growing attention of the scientific community to the problems related to the pollution of the atmosphere. During these years, Important new Issues have arisen (global pol lutlon/cl Imatlc changes) whl Ie old ones have been reviewed due to new experimental evidence (depletion of stratospheric ozone). The Symposium offered the best opportunity for a review of the current studies and technical progress achieved In the various sectors of the Concerted Action since the Fourth Symposium held In Stresa (Italy) In September 1986. In 1987 the scientific programme and the operational structures of the COST 611 Project were revised. The Project Is now structured into three Working Parties: 1. Development of Analytical Methods to measure Trace Components of the Atmosphere. 2. Atmospheric Chemical and Photochemical Processes. 3. Field measurements and their Interpretation.

The "European Experiment on the Transport and Transformation of Environmentally Relevant Trace Constituents over Europe" (EUROTRAC) was established in 1986 to tackle the scientific problem and combine the expertise, knowledge and resources in Europe, in order to apply them over a large region covering the greater part of the continent. EUROTRAC is a coordinated multidisciplinary scientific research project involving field measurements, laboratory studies, instrument development and development of comprehensive computer models for the simulation of the physical and chemical processes in the lower atmosphere.

As the regional models required to understand and control the generation, distribution and deposition of air pollutants become more precise, the need to understand the detailed effects of hilly and mountainous terrain becomes more acute. The Alpine regions and the mountainous Mediterranean coasts have large effets on the way the pollutant burden is spread in their areas. Similarly an understanding of the effects of chemical and physical processes controlling pollutant deposition and the emission of biogenic compounds is essential to the correct modelling of the coastal regions which surround so much of Europe. The results from two projects on these problems are presented in this volume: one involved a series of field campaigns in the Alps and in the Rhine valley, the other involves ships and platforms in the North Sea and also in the Mediterranean.

Dimethylsulphide (DMS), emitted by marine phytoplankton, is the second most important source of atmospheric sulphur, after anthropogenic SO2. In the atmosphere, DMS is transformed into condensable acidic sulphur products and, through gas-to-particle conversion, it becomes the most important natural source of atmospheric sulphate aerosols. Possible climatic effects have been suggested, linked to the negative radiative forcing due to scattering of solar radiation and especially to modification of cloud albedo over oceans by sulphate aerosol particles. These effects occur in addition to those deriving from the superimposed anthropogenic component of the atmospheric sulphate. Understanding the cycle of DMS in the marine troposphere and its interaction with the aerosol budget and cloud properties has become a key research target in these last years. Our knowledge of the many processes involved is still fragmentary, however. This book, which updates the state of our comprehension of the marine DMS cycle with special regard to its climatic impact, will be of interest to marine biologists, atmospheric chemists, aerosol physicists and climatologists, and to scientists concerned with changes in the Earth's climate.

The end result of policy-related experimental and theoretical scientific work on the abatement of atmospheric emissions is a hierarchy of computer models that can be used to analyse and predict the behaviour of pollutants on urban, local regional and global scales. Such models are required to simulate an extremely complex natural situation in which a non-linear chemistry must be included together with the vagaries of the meteorology and the terrain. This book describes recent advances in the development and application of models on all scales, and in the techniques for the estimation and verification of emissions. It includes reviews of recent work together with detailed results and provides a useful picture of the field in a European context.

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.

Interest in the occurrence and behaviour of volatile organic compounds (VOCs) is increasing due to their adverse effects on the environment and human health. It is essential that information is made available on the various aspects of research on VOCs to enable better understanding and control of the various environmental and human health threats. The information in this book will be used to improve communication and understanding of the various approaches. In particular the potential and limitations of the described analytical methods will be essential in defining environmental studies and interpreting the results.

Our understanding of the quantitative aspects of free radical chemistry and the involvement of radicals in such areas as biology, medicine, the environment, etc., has developed spectacularly over recent years, yet the various topics are commonly discussed separately, in specific meetings and specialised publications. Free Radicals in Biology and Environment draws together two important areas of free radical chemistry, using as a bridge the fundamental physical chemistry of free radicals (spectroscopic detection of free radicals, evaluation of absolute rate constants, elucidation of mechanisms of free radical reactions and catalysis, photochemical and radiation processes, etc.). The most relevant topics covered are the EPR detection of radicals in biochemical systems and in pollutant formation and degradation, oxidation processes in biology and in the troposphere, radiation and induced damage, and atmospheric pollutants arising from incomplete combustion. Also covered are the chemistry and biochemistry of nitric oxide and peroxynitrite, the chemistry and biochemistry of DNA radicals, the role of radicals in myeloperoxidase, lignineperoxidase, radicals and cardiovascular injury, radiation and the fragmentation of cells and tissues.

Oxidation and removal of atmospheric constituents involve complex sequences of reactions which can lead to the production of photo-oxidants such as ozone. In order to understand and model these complex reaction sequences, it is necessary to have a comprehensive understanding of reaction mechanisms and accurate estimates of kinetic parameters for relevant gas-phase atmospheric reactions. This book presents recent advances in the field and includes the following topics: e.g. the oxidation of simple organic compounds, NOx kinetics and mechanisms, OH radical production and rate constants for the OH attack on more complex organic compounds, peroxy and alkoxy radical reactions, photo-oxidation of aromatic and biogenic compounds, and the interaction between radical species.
