The 10th International Symposium on Solubility Phenomena was held at the Home of Scientists "Frédéric Joliot Curie" in the Sts. Constantine and Helen resort complex north of Varna in Bulgaria on the Black Sea, from 21 to 26 July 2002. Unlike previous symposia which consisted of invited lectures and papers given in non-overlapping sessions, this symposium was accompanied by a Workshop on Solubility Phenomena– Application for Environmental Improvement, whose sessions were held in parallel with the symposium, except for one joint session. One hundred-eighty participants from 37 countries took part. Of the scientific participants, 50 were from Bulgaria and 117 from elsewhere.

The new Subcommittee on Solubility and Equilibrium Data of the IUPAC Analytical Chemistry Division met over the two days prior to the symposium, with Professor Heinz Gamsjäger (Austria) as the chair. The symposium and workshop were chaired by Professor Christo Balarew, with Dr. Stefka Tepavitcharova as scientific secretary; both are from the Bulgarian Academy of Sciences.

The symposium and workshop were organized by the Bulgarian Academy of Sciences, the Subcommittee on Solubility and Equilibrium Data, and the International Centre of Black Sea Studies. IUPAC was the majorsponsor of the symposium as part of the IUPAC program to provide financial support for international symposia in developing and economically disadvantaged countries. Support was also received from the Bulgarian Academy of Sciences; the UNESCO Regional Bureau for Science in Europe, Venice; and the U.S. Army Research Development and Standardization Group, UK. Sponsors for the Workshop, in addition to the Bulgarian Academy of Sciences and UNESCO, were the International Centre of Black Sea Studies, Athens; the European Commission, Directorate General Research; Intergovernmental Oceanographic Commission, Paris; International Ocean Institute, Malta; Cesum-BS, Centre of Excellence, Varna; Chernomorski Solnizi AD, Burgas; and Black Sea Technological Campany, Varna. The symposium and workshop received good coverage in the local Varna press and on Bulgarian radio.

The opening ceremonies were presided over by Professor Balarew, symposium chair. Professor Ivan Gutzow (Bulgaria) gave the opening plenary address on "Solubility and Crystallization in Biological Fluids and the Problems of Life and Health," a topic that served as an excellent introduction to both the symposium and workshop.

The Symposium was organized in 12 sessions divided among the four sections: Quantitative Structure-Solubility Relationships; Solubility Diagrams, Phase Relationships, and their Application; Application of Solubility Data for Environmental Improvement of Polluted Waters and Soils; and Application of Solubility Data in Marine-Type Solutions and Industrial Waste Treatment. Fourteen plenary lectures and 21 contributed papers made up these sessions, and 47 posters were presented during two evenings. The contributions themselves covered a wide spectrum of solubility phenomena, from fundamentals of dissolution processes through new data and modelling of solubility processes to many applications.

The workshop was organized in six sessions divided among the three sections: Pollution Level and Pollution Sources of Danube, Dnieper, Dniester, Bug, and Other Rivers Flowing into the Black Sea; Black Sea Fluxes, Monitoring of the Black Sea (including a roundtable discussion); and Reinforcement of Regional Participation in Integrative European Programmes for Solving Ecological Problems (with a roundtable discussion on regional cooperation). Three plenary lectures, 25 contributed papers, and 28 posters were presented. The plenary lectures given at both the symposium and the workshop are to be published in Pure and Applied Chemistry under the editorship of David Shaw (USA).

The extensive participation of delegates from countries with Black Sea coastlines, as well as of those from countries that have historical, economic, and political connections with the Black Sea, was a noteworthy feature of the workshop. The workshop thus provided a valuable forum for scientific workers to meet one another and to learn of the several national and international programs that are addressing the many problems connected with the ecological health of the Black Sea.

Participants enjoyed a half-day excursion to Balchik, followed by a memorable dinner at the Ethnographic Complex "Chiflika" in the village of Chukurovo in the Dobrich region.
