This book deals with the sources, distribution, analytical methods, and monitoring of Polycyclic aromatic hydrocarbons (PAH) in the occupational environment. It is hoped that this book will make a contribution to understanding the formation and determination of PAH in work atmosphere and that it will make a particular contribution to occupational health projects. Much of the information given in this book has been generating in studies carried out in cooperation with the Norwegian aluminium industry.

This volume concerns sources of polycyclic aromatic hydrocarbons (PAH), their emission factors, and relative importance. It deals with exposure, uptake, metabolism, and detection of PAH in the human body. The volume contains an update of information in environmental and biochemical studies of PAH.

More than 10 years after the "First European Symposium on Organic Micropollutants in the Aquatic Environment," the "Sixth Symposium" was held in Lisbon (Portugal) from 22 to 24 May 1990. The Symposium was organised within the framework of the Concerted Action COST 641 * which is included in the Fourth R&D Programme on the Environment of the Commission of the European Communities expiring at the end of 1990. After restructuring the Concerted Action in 1984, particular attention has been devoted to fate and transformation of organic micropollutants in the aquatic environment. Therefore, a major aim of the Symposium was to review current studies and progress in these areas, besides more general aspects related to analytical methodologies and behaviour of pollutants during water treatment processes. This volume contains the plenary papers presented in the following sessions at the Symposium: - Multidisciplinary studies - Partitioning of organic micropollutants in the aquatic environment - Novel analytical techniques in environmental chemistry - Monitoring micropollutant - Degradation of organic micropollutants during field conditions - Reclamation of polluted ground water - Chemical and photochemical oxidation - Future of environmental chemistry. In addition, extended versions of posters are included, covering the four topics which are dealt within the four Working Parties forming the structure of the Concerted Action: 1. Analytical methodologies 2. Transport and distribution 3. Transformation reactions 4. Water treatment. We believe that the Proceedings give a good overview of current activities in these fields of research in Europe.

The "Fourth European Symposium on Organic Micropollutants in the Aquatic Environment" was held in Vienna (Austria) from 22 to 24 October 1985. The Symposium was organized wi thin the framework of the Concerted Action COST 641* which is included in the Third R&D Programme on the Environment of the Commission of the European Communities. The aim of the Symposium was to review recent scientific and technical progress in the area of organic micropollutants in the aquatic environment and to present relevant research papers related to analytical methodologies, transformation reactions and transport of organic micropollutants in water, and water treatment processes. A special session was devoted to theoretical aspects and future acti vi ties. Furthermore, special poster sessions were organized where original contributions were presented. This book presents the Proceedings of the Symposium including all review papers, presentations of research papers and extended versions of all posters. We believe that these Proceedings provide a good overview of the activities in this field in Europe. We are confident that it will constitute a valuable contribution to the understanding and solution of the problems posed by organic micropollutants in the aquatic environment. The Commission of the European Communi ties whishes to express its grati tude to the co-organizers of the Symposium, Bundesministerium fUr Gesundheit und Umweltschutz, Wien, and Der Osterreichische Wasserwirtschaftsverband.

This volume contains oral papers and posters presented at the "Fifth European Symposium on Organic Micropollutants in the Aquatic Environment" held in Rome (Italy) from 20 to 22 October 1987. The Symposium was organ- ised within the framework of the Concerted Action COST 641*) which is in- cluded in the Fourth R&D Programme on the Environment of the Commission of the European Communities. As for the previous symposia, the aim was to review current studies and technical progress in the area of organic micropollutants in the aquatic environment, particularly since the last symposium held in Vienna in October 1985. The programme consisted of review papers and posters re- lated to analytical methodologies, transport and transformation of or- ganic micropollutants in water, water treatment processes and mathemat- ical modelling. Special sessions were devoted to laboratory data treat- ment and environmental scenarios. These proceedings provide a good overview of the activities in this fieiu in Europe and constitute a valuable contribution to the understanding and solution of the problems posed by organic micropollutants in the aquatic environment. The Commission of the European Communities wishes to express sincere thanks to the co-organizers of the Symosium, in particular to Mr A. Liberatori and T. La Noce of the Consiglio Nazionale delle Ricerche, Istituto di Ricerca sulle Acque, Rome.

The Commission of the European Communities presents with this volume the proceedings and the conclusions of the second European Symposium on the analysis of organic micropollutants in water. This symposium has been organized within the framework of the Concerted Action "Analysis of Organic Micropollutants in Water." This research programme is jointly implemented by the European Communities and Norway, Portugal, Spain, Sweden, Switzerland and Yugoslavia within the framework of a COST (Cooperation Scientifique et Technique) agreement. The project, also known as COST Project 64b bis, aims at coordinating all relevant research in this field in the participating countries. An effort is made to improve methods and techniques for the identification and quantitative determination of organic compounds present in all types of water. The symposium permitted to review the results achieved during the past three years of research in the following areas: - Sampling and sample treatment - Gas-chromatography Separation of non-volatile compounds, in particular high performance liquid chromatography (HPLC) - Mass-spectrometry - Data processing - Specific analytical problems, in particular the analysis of organic halogens and phenolic compounds. The volume gives a rather complete overview of the activities in this field in Europe. We are confident that it constitutes a valuable contribution to solving the important problems posed by the huge number of already identified or yet unknown organic pollutants in water. The Commission of the European Communities wishes to express their sincere thanks to the co-organizers, the National Board for Science and Technology, Dublin and An Foras Forbartha, Dublin.

In this book, the proceedings of the Third European Symposium on "Analysis of Organic Micropollutants in Water," held in Oslo (Norway), from 19 to 21 September 1983, are presented. The symposium was organized within the framework of the Concerted Ac tion COST 64b bis *, which has the same name and is included in the Third R&D Programme on Environment of the Commission of the European Communi ties - Indirect and Concerted Actions - 1981 to 1985. The aim of the symposium was to review the progress and results achiev ed during the past two years, since the Second symposium, held in Killarney (Ireland) in November 1981. The programme of the symposium consisted of review papers covering dif ferent areas related to the analysis of the organic pollutants in water, in cluding sampling and sample treatment, gas and liquid chromatography, mass spectrometry and specific analytical problems for some types of compounds. We think that the volume gives a rather complete overview of these activities in Europe. Moreover, the paper presented by D. Hunt reviews the development of the new technique mass spectrometry - mass spectrometry in the United States of America. Some special sessions concerned the presentation of original contri butions in form of poster, the extended versions of which are published in this volume."
