Since the discovery by J. E. Lovelock, R. J. Maggs and R. A.
Rasmussen, in 1972, of its ubiquity in sea water, dimethyl sulphide
(DMS) , a biologically produced sulphur compound, has been the
subject of continuously increasing interest by the scientific
community. DMS was immediately recognized as an important component
of the biogeochemical sulphur cycle, and is now indicated as the
second most important source of sulphur in the atmosphere, after
anthropogenic so emission from fossil fuel combustion and 2
industry. DMS reacts rapidly in the atmosphere where it is oxidized
to condensable acidic sulphur products; in fact, rainwater
acidification, observed in remote areas, is attributed to DMS
emissions. The hypothesis of a climatic role of DMS was made
already in 1983 by B. Shaw, and by B. C. Nguyen, B. Bonsang and A.
Gaudry. In 1987, a study appeared in Nature, in. which R. J.
Charlson, J. E. Lovelock, M. O. Andreae and S. G. Warren suggested
the possibility of a partial control of the climate by the
biosphere through a chain of processes, linking production of DMS
by marine phytoplankton with changes in clouds albedo. The
publication of this paper triggered a strong debate and stimulated
new efforts to describe the various aspects of the DMS cycle in the
environment. The paper was timely and added to the discussion on
the relative roles of atmospheric sulphur and greenhouse gases in
the Earth's radiative budget.

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.
Le rassemblement sur la zone industrielle de FOS-BERRE d'une
densite importante de mesures meteorologiques et physioo-chimiques,
per- met de proposer, dans Ie cadre de notre action COST 61 a bis,
l'utilisa- tion de ces mesures pour initialiser et verifier divers
types de modeles. L'objectif initial de cette campagne est
l'intercomparaison d'instruments de teledetection. II s'agit d'une
des campagnes effectuees periodiquement, en des sites differents a
l'initiative des Communautes europeennes. Ces campagnes comportent
deux phases: la premiere est l'inter- calibration des instruments
au m@me point, et la seconde est l'estimation des flux de polluants
sur la zone etudiee. Effectuee en general a l'aide de moyens
mobiles de teledetec- tion, cette estimation ne peut @tre assuree
que si lion connatt Ie champ de vent et Ie profil vertical de
temperature (et, bien sOr, les caracte- ristiques des sources
polluantes). L'Etablissement d'Etudes et de Recherches
Meteorologiques de la Meteorologie Nationale (EERM) et Ie Service
Etudes et Recherches de l'E- lectricite de France (EDF) sollicites
pour fournir l'assistance meteoro- logique correspondante, ont
propose, du fait de la presence de moyens im- portants sur Ie site,
une campagne mesometeorologique. Ce deuxieme objec- tif a permis
d'obtenir des donnees tres completes, que les modelisateurs
europeens devraient pouvoir utiliser. II - Aspects meteorologigues,
reconstitution des champs Le site de FOS-BERRE se caracterise par
sa geographie tourmen- tee: presence de la mer, de l'Etang de Berre
et de reliefs. Toutefois, Ie mecanisme engendrant les fortes
pollutions reste en gros Ie m@me que sur site homogene.
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 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.
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."
